It had already been three days since Isuzu and the others had challenged the 'Raglander's Company'.
　Each day's challenge lasted less than three hours each time.
　They were so exhausted that they couldn't stay in the dungeon.
　Of course, it's not enough to stay in the dungeon for a long time, but it's a problem to stay in the dungeon for such a short time. I'd only managed to complete 4 or 5 battles.

　There is no choice but to repeat the training.
　Rundel House had concluded that forcibly, but there was no way he could earn enough experience in a mere four or five battles. Every time it became a melee or a confusing battle, they would wear out their MP and mental power and then retreat. This is the repetition of this process.

　Right now, Isuzu is changing into her normal clothes instead of her leather armor.
　It was because she would get tired if she had to wear heavy gear until she returned to camp.

　Isuzu and the others, who have rounded up the entire morning because the upper party dives into the dungeon for about six hours every day, had nothing to do and were left with nothing to do.

　If they took an hour's rest outside the dungeon, they could recover their HP and MP.

　That being the case, we can enter the dungeon again in the afternoon, and if we did so, we could gain a little more experience, but this was forbidden by Nyanta and Naotugu and others. I don't know why, but they strongly told me to, and as expected, I can't disobey them.

　There was no choice, and Isuzu and the others would do chores such as picking up firewood and carrying water, and also pass the time by taking a walk.

　It was probably three o'clock in the afternoon, judging from the angle of the sun.
　Isuzu was heading to a nearby pond.

　It's not a big pond, but it is cool and clear thanks to the stream flowing into it from the stream, and the group gets their water for drinking from here. We didn't try it because we might get an upset stomach if we used it as drinking water, but Isuzu's intuition tells us it was safe.

　Naturally, there is no such thing as a hot tub in the mountains.
　It's not that anyone said this, but Isuzu and the others take turns coming to this pond to bathe in the water.

The first thing you need to do is to take a bath.　--Ha!
　A compressed exhalation leaks from deep in the forest.
　Who could it be?
　Isuzu quietly turned around in that direction.

　It was Rundell House, exercising violently in the forest. The figure, wearing a mage's cloak over a wisteria-colored, wisteria-colored outfit that looked like the uniform of some prestigious boarding school, was drenched in sweat.
　I don't know how long he had been moving like that, but if the black stain on the ground was sweat, he might have been training long after escaping the dungeon.

　Rundelhaus thrust out his left hand and created a huge mass of fire, which he just barely compressed into a fist-sized fireball. The process may require a great deal of concentration, and sweat was drenched in sweat on the face of a supposedly fashionable person.

　Throwing the fireball at him, he quickly formed a mark and fixed it in the air before it hit the trees. This time, he created the same mass of ice and cold air and ejected it to annihilate the flames that should have been fired by himself versus the flames.

　The magic power converted into flame and ice collides in the trees of the forest, giving off intense steam. While avoiding its splashes, which at times are like boiling water, Rundel House continues to move without stopping for a moment.

　It must be training for real battles.
　Isuzu found two lines drawn underneath Rundel House's feet. At first, Isuzu didn't understand what the lines were for, but after watching Rundel House's movements for several minutes, she suddenly understood.

It's a dungeon, a passageway.

　On the dirt of the ground, two lines, only drawn, represent the dungeon's pathways. Rundell House is fighting against a swarm of invisible skeletons coming from beyond.
　They are moving back and forth incessantly, but they do not move across the line to the left or right. They can't move. This was because there was a "wall of passage" there.

　How long did I move?
　It seems like a long time, but probably only about five minutes. Rundelhaus let out a huge breath as he knelt on the ground. He was in an almost vomiting position, desperately sucking in air from his pathetic sounding throat.

'Is it okay...?'
　From behind the trees, Isuzu called out hesitantly.
　It was because she remembered a classmate of hers with asthma who had these symptoms when she was at her most distressed.

　However, Rundelhaus seemed to be truly surprised by the voice. He stood up in an instant, as if it were a spring-loaded device, and turned toward Isuzu with an electric gesture.

''Hi, Miss Isuzu. ........Hey, what's going on here?
　With a princely smile, Rundelhaus ruffles his bangs in a refreshing manner.
　But in reality, his sweat-covered bangs end up sticking to his forehead in a sticky way.

'No need to push yourself, okay?'
　Isuzu will say that while holding back a laugh. However, it doesn't seem to have gotten through to Rundelhaus. On the contrary, he is more than a little flustered and mended.

''What are you forcing me to do?　I don't think so. I was just taking an afternoon stroll in the woods to listen to the harmony of the birds and the nymphs.
　Just by speaking that much dialogue, Rundelhaus turns purple in the face.

You're right, of course. You're so oxygen-deprived that you can't even get a word in edgewise, and you do the prince's line. I'll get cyanosis...

　Isuzu thought so, but the princely smile of the Rundel House didn't break even as her face turned purple. As expected, I decided to look away and give her a pathetic look and turn her back to him as well.

''Oh, I see.''

　When I call out to him over my back, I hear a coarse breathing sound at my back.
　In the middle of a forest where there is no one around and it's just a man and a woman, the sound of a man's coarse breathing is a sure sign that a pervert is out there, but from Isuzu's point of view, Rundelhaus is a very frivolous man, and he's in the mood to show the mercy of a warrior.

(Hmm, is that weird, or am I weird?)

　If you think about it, Isuzu and Rundelhaus are on the same level. I'm not sure of their ages, but Rundelhaus looks to be in his early twenties, so I wouldn't call him younger than Isuzu. I'm not sure how old he is, but he's not a man, and he's not very carefree.
　It's not just a matter of time before you'll be able to get your hands on one. Isuzu is a support person and Rundelhaus is a pure attacker, but their offensive power is more than five times greater than that of Isuzu.

　Therefore, there is no point in Isuzu treating Rundel House as a petty person.

　However, Isuzu seems to feel a sense of superiority over Rundelhaus on a completely different level than the meaning of her abilities and conditions. It was a state of mind that I don't understand.

''Miss Isuzu - well. What is she doing here?
I'm going to have a bath. Oh, yeah. Mr. Rundelhaus will join us.
　Would you like to go?　I did not say. This is unusual, considering the usual Isuzu. The feeling of restraint towards the Rundel House has been completely removed.

'Bathing!　I have no taste for watching ladies bathing!　Let's have you not spoil it!
No one said anything about going in with you or showing you.
　Isuzu keeps her back to me and does it back with an angry laugh. It feels good to hear Rundelhaus coughing, still not breathing properly.

''It's not good to let a lady walk alone in the forest, is it?
　Isuzu blushes a little. It's kind of terribly embarrassing to call herself a lady. To be honest, it's an outrageous statement. However, you can't retract that which has once come out of your mouth.

I'm not sure if that's true. I'm sure you'll be able to find it.
　Rundelhaus' voice regained its strength.
'Then I shall send you on your way. There is a fountain, is there not?　Which one is it?

　Isuzu spun around and turned around.

　There's Rundelhaus, who looks a bit amused, "Mm, show me around. Though drenched in sweat, his blonde hair never faded, and in this way, he's still handsome. If he were on real Earth, it's not a bad line to make him the star of a shoujo manga.

(I don't feel much pressure to do so. ........maybe it's another inter-dimensional effect)

Over there, Mr. Rundelhaus.
　The young man calls out to Isuzu as he walks along the beast path to the pond, craning his neck.

'Miss Isuzu. You can call me Rudy. That's what my parents call me.
　Isuzu listened to his voice with a ticklish feeling.



　◆



　The place they were brought to was deep in the "Old Court of Eternal Ice", a section that Shiroe and the others had never heard of before.
　In this area, deep inside the court, the silence and cold air was strong even though it was summer. Just as the cool air was about to go from 'cool' to 'chilly', they were confronted by a huge, carved, metal door.

Now, here's my roost. Come in, come in.

　Li-Gun, who calls himself a sorcerer, pushes open the door and invites you in, and inside is a study that seems to contain thousands of books. In the center of this space, which at first glance appears to be nothing more than a huge passage with a high ceiling, there are several tables and sofas installed.

　Surrounding it are piles of books piled up like small mountains.
　The walls of the huge corridor are flanked by stacks of books twice as tall as Shiroe, who feeds off of his own food in the form of calligraphy. Scribblings and scrolls overflowed, so much so that they caused a small avalanche in places.
　And the scene continues into the back of the room until the vision sinks into darkness.

　Speaking of that Li-Gun, he is stirring around the table and desk, wondering, "Hey, that's funny," "Where did he go?" and so on. Shiroe and Akatsuki took over one of the sofas without permission. Although that required adding some of the books that were on the couch to the pile on the floor.

'No, sorry. I believe there was a pot for drinks available somewhere.
　To a horrified Li-Gun, Shiroe shook her head and said, "That's fine. He then takes out several glasses and a large bottle of black rose tea from the bag he wears.
　This standardized drink tastes like a thicker version of hojicha, but with less astringency and is drunk with honey and sugar. The one Shiroe carries around with her is the iced type, cooled with fresh water and sweetened with syrup.

　Shiroe poured it into her, Li-Gang's and Akatsuki's glasses as well. Li-Gang's face lights up as he drinks the tea. He was a strange man, a skinny little man, but there was something charming about him.
　At least in terms of apparent age, he looks not much older than Shiroe.

'Thank goodness. I'm not at all good at finding things.
--It's Dazanegh's Magic Bag, isn't it?
Yes. I've had it made before.
　Shiroe nodded honestly at the question.

''Hmm. I've studied that bag before........ You need the purple flame crystal and the pterodactyl's skin for magic circuit crystallization, right?''
'Yes. So I got the item and had it made to order.
　Shiroe is impressed. It seems that this sorcerer Li-Gun has a pretty accurate grasp of the content of the quest 'Get the Magic Bag' that you can receive when you reach level 45. The amount of knowledge that you can't believe that he is an earthling.

''I beg your pardon. I'm sorry. My name is Li-Gun. I called myself a sorcerer earlier, and I can also use magic, but to be precise, I'm a magician.
A magician?
'Yes, you're a researcher who studies magic. I can also teach general magic, but I'm more of a researcher.
In here?
''Yes. It's been 30 years since I lived in this 'Ancient Court of Eternal Ice'. This used to be my master's laboratory, but he passed away more than ten years ago. Since then, I have been studying here following my master's work. I am sorry for my poor appearance.
Myral Lake. ...the wise man of Miral Lake, is it?
　Shiloe remembers Li-Gan's name and huffs at the name.

　The Wise Man of Miral Lake.
　It was information he had heard in several quests, rumors in the city, and books during the Elder Tail era. For example, the key item in the large-scale battle of the "Ninth Prison of Halos" is said to have been made by the Wise Man of Miral Lake.
　But I didn't pay much attention to it because I thought it was just a game and background information to enhance the story.

I'm sure you're not the only one. I've rarely called myself that, though. I'm still not out of the woods yet. I can only think of you as a master.
Are the Wise Men of Miral Lake hereditary?
It will be. Please call me Li-Gun.
　It was a very low profile greeting for a man who inherited his name. There is almost no intimidating feeling that is associated with the word "wise man".

　A silence passes between the two of them.
　Slowly quenching his thirst with black rose tea, Shiroe continued to think at high speed. His appearance at the Free City Alliance Eastal's Lords Meeting was partly due to the other party's request, but more importantly, it was the result of his focus on gathering information on the current situation. Attending this Council of Lords would allow him to gain acquaintance with the ruling class of this world, or at least the political class. If that happened, he had expected to obtain information that was far more extensive than the rumors in the city.
　But I didn't expect such a big name to fall for it.

　It had been three months since the catastrophe.
　Various knowledge of this world is slowly but surely being brought to Shiroe and the others. At the very least, we now have what we need to know to survive in this world. Shiroe and the others in Akiba have access to food, clothing, and shelter from the rain and dew.
　But the more knowledge they acquired, the more they realized that they didn't know anything.

　If Shiroe was the only one, there was no problem.
　Or, if she's just living with a few friends, most of her problems can be solved. Regardless of what the Daichijins think or the reality of this world, Shiroe and the others are capable of surviving in this world. They have the ability to survive, whether it's traveling or setting up a base somewhere deep in the mountains.

　However, Shiroe is not in a position to think about such things right now, nor does he want to. There are fifteen thousand people in Akiva's city. In all, there are nearly 30,000 adventurers (players) on this server.

　With this many adventurers, they couldn't just travel and live in secret, hiding from the Daichijin. They cannot live their lives in secret, nor can they hide from the Earthlings.

　In this Japan Server Management Area, where the population is probably only about a million, Akiba's population of fifteen thousand is too large. The mere act of taking any action would have too much of a ripple effect on this world. In fact, new methods of item creation are having a huge impact on this world.
　--Of course, even if Nyanta hadn't discovered that level of ingenuity, a few months later someone would have discovered it and spread the word. That was a psychological breakthrough that was taken advantage of because of the panic and discouragement caused by the 'catastrophe'.
　Therefore, Shiroe is not responsible for the spread of that new item creation method. However, he only needed to be aware of the fact that that knowledge had affected the world.

　And such a situation would have to happen in the future. No matter how you look at it, these adventurers are foreign to this other world. To steer the outcome in as gentle and non-destructive a direction as possible, a deep knowledge is needed. The current Shiroe and the others were overwhelmingly lacking in that knowledge, by far.

(This conference......... Probably more important than the Lords Conference)

　Li-Gan looks at Shiroe, his expression tightening, with interest, and begins to speak.

It's not just a matter of time before you'll be able to get your hands on a new one. It is a huge range. I specialize in the study of world class magic.
World class.
　Hearing the unfamiliar words, Shiroe nodded with a hand to her chin.

''Yes. It's a way of classifying magic by the scale of its effects. It's the movement level, combat level, operational level, tactical level, strategic level, national defense level, continental level, and world level. Of course, these classifications are one-dimensional. In addition to classifying by size, it is also possible to classify them by characteristics such as those that deal with energy, those that change the state of things, and those that deal with summoning, as well as by the ability of the magician.

　Shiroe listens to the conversation and continues to think.
　It's certainly an unfamiliar concept. I'm sure that the type of magic, for example, that deals with energy, is that of a "sorcerer". I'm sure you'll be able to find a way to make it work. It's understandable that they are treated as such. It's an easy way to understand.
　It is also understandable that they are divided according to the ability of the wizard. I'm not going to be the only one who's been in the same boat for a while," he said.

The classification by scale is a way of classifying magic in terms of its scale, phenomenology, and purpose.
　The action class represents the extent to which a single action can be substituted by magic. For example, a magician wields a sword to wound a demon. If the magic does this by magic, it is the action class. This is because the effect of "wounding a few monsters" can be done with a single action. So most of the magic used by the magicians is of the action class. Even if the attack power is increased, the action class is only action class.

　The basic attack spell Shiroe uses, the Mind Bolt, is a motion grade spell. It's a spell that uses magic power to create a mental damage shockwave, but its effect is almost the equivalent of shooting a bow and arrow. There are damage and blessed effects, but they are only incidental.

The battle grade is the magic that determines the outcome of a single battle. It's a magic that can determine the fate of the enemy platoon or a friendly platoon by using that one magic.
　Apparently, this classification by magic scale is quite profound. For example, the hypnosis spell Shiroe uses, Astral Hupuno, is an "action class" in its own right. However, depending on how it's used, it has the power to bring all enemies of a platoon size to the brink of death. In that case, it could be classified as a "battle-class" weapon.

''An operational grade is a magic that is large enough to affect two to three battles together. It is said that the great magic wielded by the legendary battle magicians of this world can be classified in this category.
　Multiple battles, and if so, would it be a powerful ability-granting sorcery?　Even if Shiroe searched all of his magic arts, he could only find one speciality that reached this rank.

''The tactical level is the stage above that. For a day or a few days, in terms of a group of enemies, it would be a magic that is large enough to influence a fortress, a tower or a mansion in a single blow.

　Having come this far, Shiroe was beginning to exceed the limits of his imagination.
　If it was a simulation game, Elder Tail was an RPG in which the player was the sole player. If the adventurer as an individual has that kind of destructive power, then there is no need for cooperation between the players. That's an overwhelmingly destructive force.

The rest is just a rush. The strategic level is a single magic that can influence a single war. You're going to be able to get the most out of it. The continental level is the magic that can affect an entire continent, even if it's viewed on a map. And the world class is...
A magic that can affect the survival of the world, its laws, its destiny...?
That's right.

　I understand the concept.
　If it's a subject of study, I can understand it. But is this kind of magic really real?　No, it's Shiroe, who is on the fringes of the Elder Tail world as a sorcerer himself, an enchanter. It's ridiculous to doubt the existence of magic, but the scale of the story is so large that it didn't make sense to me.

''Well......... Excuse me, but it's more like an assumption. I can understand the classification itself. Does such magic actually exist?　Is this a theoretical subject for your research?
　Li-Gan denied Shiroe's question with a smile.

It exists. It's not just a matter of time before you're ready to go. I'm sure you'll be pleased to know that this magic is called the World Fraction.
It's not within the reach of the earthlings or adventurers, but a volcanic eruption caused by a spirit of fire, or a major earthquake caused by an earth spirit - these are all ways in which national defense-class magical disasters can occur.

　I'm not sure if this is a good idea or not, but I'm sure it's a good idea to have a good idea of what you're talking about. I'm not sure I've ever heard of it. It's true that it makes sense if you think of it that way.
　This skinny researcher named Li-Gun has a vision that goes beyond the magic used by individuals. Indeed, he is not a 'magician' but a 'magic researcher'. His ambition is not to expand his abilities, but to uncover the mysteries of the world. It is tantamount to an ambition to unravel the structure of the world.

"You call what happened in May a 'catastrophe', don't you? The Daichijin simply call it the 'revolution' or the 'May Incident,' but I call it the 'Third Great Transformation. The purpose of inviting you to speak with me this time is to learn whatever information you have on the 'forest transformation'. As a researcher, I am interested in knowing everything that you have.
　Li-Gan's eyes seemed sincere, though they glittered with curiosity.

(Talking is fine. There's little we know about it anyway. But.........)

Did you say "the third one"?　-- which means that there are traces of world class magic being used in this world before. Can I tell you that story?　We adventurers don't have much information on the Catastrophe. I'll tell you about it. But we need to know as much as we can about the Catastrophe.



　You're not going to be able to do that.



　Li-Gan took a beat at Siloe's words by taking a drink.
'That's fine, but this story is going to be a long one. Would you still like to?'

Yes, please.
　Shiroe makes sure that the Akatsuki next to her nods silently before replying to Li-Gun. Akatsuki also seems to be listening to the conversation with a nervous look on his face.

''I suppose so. Where shall I begin to explain? I'm sure you'll find that you'll be able to find out what's going on in this situation. No, in fact, it would be fair to say that I don't understand almost anything.
　Therefore, it's terribly easy to just say, 'It happened a long time ago', but I don't think that would be enough to explain it. That's fine. From the roots as far as I can tell. ....Let's start with the old story.

　Shiroe nodded deeply as she repositioned herself on the couch.
　That was something Shiroe would have liked to see, given the circumstances in the first place.

'About 350 years ago now. They say that this world was much more prosperous than it is now. Of course, there is no comparison to the 'old world' that has sunk into the depths of legend, but the human population was three to five times larger than it is today. Humans were mainly active on the continents, and their influence was widespread and extended to the ends of the earth.
What's a continent?
Yeah, it's your neighbor Yuled.

　Eurasia. It's a continent that includes China, Middle Eastern countries and Europe," said Shiroe, nodding his head. I'm sure you'll be happy to know that this is the largest continent in this other world.
　I'm sure you'll be able to find a way to make it work. According to Elder Tail's game-like background legend, this world was the reconfiguration of the Old World, with its highly-evolved scientific civilization, torn apart and reconfigured. The only thing I saw on the official site was that the reconfiguration was followed by a long period of darkness, so my impression was that the Old World was reconfigured, and then the Elder Tail game began.

　However, the buildings and roads in the Old World have fallen into such a state of decay. Come to think of it, something must have happened during those blanks. Or maybe that's the dark period.
　Is it that dark period that Li-Gun is talking about?　I had always thought it was a blank period without any events such as the Dark Ages, so I was caught off guard.

'The world was inhabited by four races: humans, alves, elves and dwarves. They glorified each other and the nations were peaceful and rich. Many of the high-performance magic items that can still be found deep in the dungeons today are from this era. Also, magical ruins like the 'Old Court of Eternal Ice' where we are now, clearly belong to a different lineage than the 'Old World', right?　These ruins were created by Arv during this era.
　Yes, Arv was the inventor of magic and the pioneer of a powerful magical civilization. It is said that they created all sorts of magical instruments and revealed the mysteries of this world.

　Arv. It was described as "an ancient race that has already been destroyed," according to the official explanation. Although Shiroe is a distant descendant of the Half-Arv, she has never felt any kind of history in her play. I'm not sure if it's a good idea for me to say that they are a race with high magical ability and aptitude for using magic tools.

I won't bore you with this since it's not relevant to the main storyline, but it was pioneered by an apprentice. I'm not sure if it's a good idea, but I think it's a good idea to have a good idea of what you're talking about. The number of people didn't increase, and the Arv kingdoms here and there were all small in size.
　And the Arv-based kingdoms were being destroyed one by one by a coalition of other tribes that resented the fact that such a small number of tribes had a monopoly on magic technology.
　--It was the downfall of the Arvic kingdoms. The glorious history of the Arvic kingdoms came to an end.

　Since the Arv tribe is extinct, is such a thing possible?
　Although Shiroe himself is a descendant of that Arv, that tragedy did not incite Shiroe to ethnicity. It's also a setting like that, or that's the extent of my understanding.

Shiroe-sama is 'Half-Arv', isn't he? "You're a Half-Arv, aren't you, Half-Arv, and you don't know why the Half-Arv have survived the extinction of the Arv?
　In other words, that is what the end of the Arv system is all about. The numerous kingdoms of the Arv tribe were destroyed, and the most valuable thing was the knowledge of magic, followed by high-performance magical tools. And next to them were the Arvs themselves. The Arvu became slaves to the world. Everywhere and everywhere - in the kingdoms of men, of elves, and of dwarves - the Alves were bought and sold. Their blood was raped and their blood was diluted to make them the Half-Arv that we know today. But nowadays, it's only possible for them to be born from human parents in a haphazard fashion.... Oh, but I digress. I shouldn't get off topic.
　It's a good thing that you're not the only one who's been in a position to do this.

Six Tilt Princess...?
　It was an unfamiliar word. Li-Gan traced the letters on the table with his fingertips. Six, six, I suppose. Leaning, princess. Leaning, princess.

There are many theories as to the identity of the Six-Tilt Princess. In this case, the identity of the Six Tilt Princesses is more a matter of individual names and origins. But what we do know for sure is that they were the princesses of a number of Arubian kingdoms across the continent.
　Incidentally, the name Six Tilt Princess was given to them by a later historian, and they themselves were neither acquainted nor in cahoots with each other.
　Like the majority of Arvites, they were enslaved by the human world. They must have been lucky not to have been executed, since they were of royal origin. According to history, they were loved like jewels because of their excessive beauty. She was held as the lapdog of the royalty, tycoons and rulers of the various nations of the time, and was kept in six different countries.
　But these women did not end up as slaves. Some were enslaved by their magic. Some led the enslaved people of Arv, while others cajoled royalty to rule their societies from the shadows and wage war against all of humanity.

　I'm sure you'll be happy to know that I'm not the only one. I'm not going to be able to say that I'm not the only one, but I'm also going to be able to say that I'm more of an Arubian.
　I'm sure you'll be able to find a way to make it work. It's not a good idea to be outraged just because they were attacked by a counterattack.

It's a good thing that you're not the only one who has the ability to do this. Thus began a tremendous muddle of battles.
　The reason why it became a quagmire is because of humans and dwarves. Humans and elves. The Elves and Dwarf nations began to fight each other.
　The Six Tilt Princess was not a hero. She was an avenger. They were intent on outwitting humanity by outwitting, confusing and misleading the public mind. It is said that many human beings died in these battles. If the records are correct, the death toll is comparable to that of all the humans in this world today.
　However, the Six Tilt Princess was also hunted down. They are, after all, of the Aruv lineage. Their weakness comes from their weak fertility and their low numbers. Even if they are hiding in the shadows of vengeance, they are vulnerable if they are discovered. Just when the Six Tilt Princess was about to be struck down, the First Morula Transformation was launched.

The first...
　Shiroe bites down on the appearance of the main topic of the story.
　I noticed that Akatsuki, who is standing next to Shiroe, also seemed to be completely listening to the story.

''Yes. There is a fairly high probability that this is thought to be a high-level ritual magic used by the Alv system. Of course there are numerous mysteries that remain. Especially in terms of technology, there are so many mysteries that even the basic principles are unknown, let alone reproducing them.
　But anyway, the Forest Transformation happened.
　The effect is the generation of subhumans. ...There were no subhumans in this world until about three hundred years ago.

　-- there was no sub-human.
　That was a word I hadn't even imagined. But if that was the case, then it was understandable that human society, including the Arv system, had prospered dozens of times more than it does now. This is exactly what the earth belongs to mankind.

I don't think this is a matter of cross-breeding or biochemistry, although you talk about the emergence of sub-humans. This is the research that my master was doing, and my current hypothesis is that this 'forest transformation' may have something to do with a 'soul'.
　At least at that time, the world was overflowing with a great deal of soul material. It was because the world's population had been drastically reduced to nearly half due to repeated wars. And that soul material was used as the material for sub-human development.
　The human race, which had been reduced by the war, was put into a tight spot at once by the sub-humans that boiled up like a cloud haze from all over the place. Many cities have fallen, and an army that was supposed to be invincible has been destroyed. Most of the country has been dismantled.
　Right now, this archipelago, to use an ancient name, is called the Yamato. Of all the nations in the archipelago, only the ancient dynasty of Westarande remains from 300 years ago. The cities and capitals of the Alliance of Free Cities Ystal were nothing more than small villages in the countryside.
　With the emergence of the sub-humans, the world has changed drastically to the present-day scenario of humanity desperately defending its narrow civilized sphere while fighting the invasion of sub-humans. The world was closed to darkness. In the end, the humans defeated the Six Tilt Princess, but I think it is safe to say that their revenge was successful.

　The Six Tilt Princess was defeated.
　The Morinara Transformation was activated.
　A mass outbreak of sub-humans using souls as materials.

This is the Dark Ages. As I mentioned earlier, all over the world, sub-human species such as goblins, kobolds, orcs, ogres, troglodytes, knolls, safagins, and lizardmen were screaming at the top of their lungs. These cruel and disgusting life forms invaded the human civilization. Humanity gradually darkened its life.
　Nowadays, research has progressed, and defensive magic and warding techniques - which are also the heritage of the Arv system - have been developed. However, in those days, those aids
　So, according to the game's specifications, when you kill a monster, it will return a certain amount of time later. It provides the player with new prey. Otherwise, the player with superior combat skills will hunt down all the monsters in a matter of minutes.

'Humanity was frightened, desperate, and hoping for a miracle. During this period, the world seemed to be really dark. Sixty years had already passed since the overthrow of the Six Tilt Princess and the invocation of the First Morula Transformation. During those sixty years, humanity was plunged into despair, poverty, starvation and fear.
　Most of humanity was trapped in armed settlements and fortresses, spending their days in fear of attacks by sub-humans and hexenbiests. Princess Six Tilt's revenge seemed to have succeeded.
　What happened there was the 〈Second Forest Luo Transformation〉. We don't have enough data on this event to discuss it clearly, as we did with the first one. It is likely that humanity was in a dark period, and there was no more room for documentation.
　The few written records document the use of the Sacred Summoning Technique, which mobilized humans, elves, dwarves, and many of the Hokage. Some scriptures clearly describe it as 'divine salvation'.... Anyway, the happened again.
　Exactly 240 years ago. --Exactly 240 years ago, the Adventurers appeared.

　240 years ago.
　The adventurers came into being.

What follows is not much to tell. The history of the Adventurers has left little to be desired. The Deadly Gara Incident, the Underworld Incident, and the Dragon's Throne Incident. Various dangers plagued Yamato, but the Adventurer overcame them all. This world was not at peace for about 240 years, of course, but it had finally gained some stability and was slowly on the road to recovery.

And that brings us to the present.

An adventurer? ........Come to think of it, Mr. Li-Gun knew my name, didn't he?　Why was that?
　Shiroe suddenly became curious and asked.

"Shiroe-sama is a great magician. I figured that you have a good knowledge of affairs among the Adventurers.
The Great Magician...?
　Shiroe twisted his head. 'I don't remember running a high ranking quest that would earn me such a reputation.

'Shiroe-sama first appeared in history about 98 years ago. Of course there are other long-lived adventurers, but based on the frequency of his activities, there is no doubt that Shiroe-sama is a great magician. Isn't that right?

(In '98!　........)

　Shiroe's brain begins to spin its circuits as if it were on fire all at once. The time of this world. The history of this world. .........then, what was the Second Morinara Transformation that occurred 240 years ago?

...the open beta has begun.
