The B-class quest area [Liesthinge's Underground Labyrinth, Dungeon] is a ruin located in the northwest of the commercial city of Hafenfeld.

　Incidentally, it is a common case that monsters live in ruins and turn them into quest areas.

　The extermination of monsters in such places is a much-needed step in archaeological research.

　This is one of the major roles that adventurers play in the world, regardless of their level.


　Heeheen! ......


　When I arrived in front of the dungeon, I left the Black King's Maru at the adventurer's stable and went to the hut marked 'Adventurer's Guild dungeon front office'.

　In some cases, guilds set up 'sub-branches' like this in front of the quest areas of ruins and structures.


''It's Eiga's territory.

　I said and handed the license from the counter to the lady at the reception desk.

"Huh? Isn't this a Class C license? This dungeon is a Class B quest area, right?

'I was promoted to Class B as of yesterday. I haven't issued my license yet, but it should be on the new report list.

'Well, Master Aega's Domain ...... Oh, there is indeed one.

'Right? Then we'll pass.

　This is how I tried to go about it.

Wait a minute.

　And the woman at the front desk grabbed my arm.

"What?

For someone who claims to be in Aega's territory, you seem to be the only one.

I'm resting my lords today.

So shouldn't you be resting too?

　Well, you're a pretty outspoken office worker.

That's up to us. It's not a violation of the quest to have someone absent from the party.

It's our guild's job to prevent any adventure that is too outrageous, whether it's a violation or not.

Rash?

Yes. It's too dangerous to sneak into this dungeon by yourself.

Hey, hey, hey. ......

　As I was arguing with her in this way, a 40 man who looked like a superior came out from the back and said

'Mary-kun. Speaking of Eiga Janes, isn't she a former member of the [Miracle Five]? You have nothing to worry about.

'The warden ....... But even in that brave party, I've heard that he, Eiga Janies, was the only one 'not very strong'. It's still dangerous.

　Well, this clerk seems to be saying it in all seriousness and not in a bad way.


　Pfft (laughs) Couscous: ......


　But you can't help but feel bad about the laughter of the adventurers around her as they giggle in response to her words.

　Many of them are happy to mock the weaknesses of those who are stronger and more famous than they are, even though they are not strong themselves, and feel as if they are a step above the rest. ......

　Nonsense.


'I'm sorry, but let me go.'

'Wait! I don't care if those people laugh at me. They say there's a species worth living for, don't they?

...... I don't care about that stuff separately. Thanks for worrying about it.

　I laughed and said that, then took the clerk woman's hand and gently put it back in my lap.



　◇



　Cuts and Jobs, Cuts and Jobs: ......


　The entrance to the dark dungeon.

　As I descended the stone stairs alone, I awakened my "ego" from my heart after a long time.


　That's right.

　Just for today, no one's training matters.

　How much can I personally fight right now .......

　You're going to be the only one who has the power to do that, and the only one who can win the battle.

　Katsunn, Katsunn: ......

　Soon, the sunshine behind me faded away and I felt myself melting into the darkness of the underground dungeon.


　The first underground floor.

　The basics of the dungeon are to find the "stairs" to the lower floors.

　However, the lower you go down, the stronger the monsters that appear and the more complicated the structure of the labyrinth becomes.

　And the Dungeon Master's 【Boss】 will be waiting for you at the lowest level.

　This entire length of the 10-story underground labyrinth 【Dungeon of the Liesthinge Underground Labyrinth 【Dungeon】】 was no exception to this rule.


　That's why the monsters that appeared were still weak in the first underground level.

　It was only a hair's breadth away from appearing in the "West side of the Domain" in Distant Cloud.

　I defeated all the monsters that appeared with a single blow of my sword while searching for the stairs.


　Catsun, Catsun, Catsun......


　But still, this is a magnificent man-made underground space.

　The aesthetic decorations on the cobblestone floors and walls reveal not only the technical level of the ancient people, but also the high level of culture.

　Shubo ......!

　I light up a cigarette as I walk away.

　Huw ......

　I'm sure you'll be able to find a way to make it work.

　I'm sure you'll find that this is an ephemeral thought, and I'm sure you'll find that your cigarette smoke is mixed with a sigh of relief.


Oh, the stairs!

　After walking around for a while, the light from the lighting magic 【Light】 illuminates the stairs to the basement second floor.

　I bent down a little bit to avoid hitting my head on the upper wall and descended it.


　Zazza Zazza......


　And then.

　The underground labyrinth gets a little more complicated as you progress through the second, third, and fourth floors, and the strength of the monsters reaches the level of Le Monde Forest.

　Eventually, on the 5th and 6th floors, the monsters in the B-class quest area began to appear here and there, and there were cases where even I couldn't defeat them in a single physical attack.


! ......

　And it was about the time we went down the stairs to the seventh basement floor for a while.

'Wow, help me out!

　Suddenly, I see a party of three people being chased by a huge boulder that rolls all over the dungeon corridor, running towards where I am.


　Rumble rumble ......

　That rock is a monster called [Rock Rock].

　If I don't do anything, I'm going to be flat broke too.


Down!

　While shouting this, I quickly unleashed a level 3 explosive magic as soon as possible.


　QUEEN: ...... bang! Bang! Bang!


　The rock rock rock was shattered by the explosive magic.

　Parapara Parapara: ......

Hi, hi. ......

　Meanwhile.

　The party of three is lying down with their heads in their hands.

　They all seem to be safe.

Good grief!

　I sighed and squatted down in front of them.

'Hey. Isn't this floor still too hard for you guys?

'Yes, yes ....... I think so.

You'd better get out of there.

Huh. But I don't have any magic left.

What?

　I scratched my head and continued.

It's all right. I'll cast a breakaway spell for you.

Really?

Yeah. In return, I'll give you the items I've acquired so far, and you can wait on the ground until I return?

　By the time you get to this point, the items you acquire are quite bulky and get in the way of battle.

Oh, my God!

　So I entrusted the luggage to them and sent the party of three to the ground with breakaway magic.

　You may think that you will escape with your luggage, but in such a case, treachery loses the trust of the adventurer community, and since we show each other our licenses, this is not the first thing that happens.

　This is how I proceeded to the seventh, eighth, and ninth floors, rescuing several 'fallen parties'.

You'll have to consider your abilities as you progress through the dungeon. It's because there are people like you who are reckless that that clerk lady is worried about you.

'Sorry ......'

　With that said, I was sending the 'wayward party' back with a breakaway magic as I went along, but that was only until the 9th floor.

　When you get to the lowest level, the 10th floor, you won't see any other parties at all.

"Everyone didn't make it this far: ......

　I was walking on the tenth floor while muttering this, but suddenly I stopped.


　Jari......

　I stepped down hard on the soil with my thumb ball.

　The sound of the soles of my shoes rubbing against the stone wall.

　Then, the hamstring and gluteus maximus muscle of the left leg, which is the axis, instantly emits force to the musculature and rotates the waist at high speed, swinging the copper sword while using the interlocking power of the shoulder and elbow!


　Whoa!


　That's when!

　Just as the 【Lion Cat】 that was lurking behind the wall was attacking, the swing of the sword 《Tsurugi》 occurred, and the blade 《Yaiba》 ate into the monster beast's throat.

　It's a formidable ......!

　Did you do it?

　However, taking advantage of that attack move, another lion cat bit me on my right leg.

It's a good idea to have a good idea of what to expect.

　I immediately crush the monster's head with my elbow and knee as if to pinch it between my elbow and knee.


　Geeeeeeeeeeeeeeeeeee!


　We're off! Now!

　I unleashed a level 3 fire magic with my left and right hands and stabbed the two of them in the end.


''Ouch, tete-tete ......''

　After the battle.

　He immediately applies a recovery spell to the right leg that was bitten by the lion-cat while kenning one leg.

　Paaaahhhh. ......*

　If you linger, you'll be too late to deal with the next monster that comes at you.

　Recover sooner rather than later, you know.


　Tattattitta: ......

　Once I finished recovering, I immediately started running.


　I heard that there was a boss [Green Dragon] on this tenth underground floor.

　That guy was the one I was after for today's 'test of strength'.

　That's why I wanted to get to the 'Boss Room' as soon as possible before the normal monsters reduced my strength.

　Seeing as how the Lion Cat suddenly appeared, it seems that this 10th floor has a few strong normal monsters as well.

　Gah! ...... squeak! Basava Sabassa......

　While I was running, the bat bats appeared next.

　You can take this thing down with a single physical blow, but it's troublesome that they attack in packs.

　If you don't take down each and every one of them completely, you'll take terrible damage.

　Bishi! Bash! ......

　But you're awfully blind.

　It's a good thing that you're able to keep up with the swift speed of Koumo Libad despite the dark place.

　Is it because I was surrounded by greenery in the countryside of Tohun?

　Pishun! Psi! Huh!

　I defeated 13 of 【Bat Bat】's 13 animals in a row and started running again.


　Then I encountered 【Spider Man】, 【Dark Krampus】, 【Red Orc】, 【Stone Doll】, etc., all of which are decently strong monsters for an 'intermediate' category with a combat power of 15,000 to 25,000.

Hahahahahaha ......

　This is how I defeated the 43 monsters on the bottom 10 floors of the lowest level, and finally reached the boss's room.


　◇


　Gogogogogo: ......

　I recovered as much as I could with the recovery pills I had on hand, filled up my magic power with demon ore, and opened the door to the 'Boss Room'.

　Geez!

　The double bass sounds like a muffled cacophony.

　A green-skinned dragon now lies like a serpent on the magnificent throne on which the ruler of the site would have once hung.

　Dosun......Dosun......

　Even the high ceiling of the Royal Chamber could be bumped against the head of the Green Dragon when he stood up.

　Ooh! Guruuru: ......

　Big mouth, fangs.

　And then, as his red eyes gleamed, the Green Dragon spat out flames from his big mouth!

　Whoa! ......

' ......

　As soon as I could, I jumped in front of his feet and dodged the flames.

　Galling! ......

　At the same time, he thrust his sword into the air and immediately attacked.

　Although the green dragon's skin is hard, he struck with all his might and the entire figure was blown off.

　Whoa! ......

　But at the same time.

　The dragon's whip-like tail struck my flank and I couldn't dodge it.

''Gosh! ......

　At the moment, I was shocked to the point of almost fainting.

　I wanted to recover, but the enemy that was struck by the stone wall has an opening, so attack first.

''Uuuh...... Fyordi!

　I unleash a level 3 ice-based magic, but the green dragon spits flames too, and the technique is canceled out (so sai).

　Tatta tatta: ......

　However, it had a blinding effect, and this allowed me to close the gap with him again.

　I jumped up and brought my sword down, but ......

　The Green Dragon also responds to this and points its fangs at me.

　Gakkien!

　The dragon's fangs attacked in front of me, but I tried to force a physical attack with my sword, minimizing the damage by deploying a localized defensive magic "defense", while I tried to force a physical attack with my sword "Tsurugi".

　is ......

　Whoa!

　He suddenly shakes his head with tremendous force, and the centrifugal force blows my body to the other side of the room.

''Hahahahahaha ......''

　The distance between them became so great that they were staring at each other, so I used my recovery magic to regain my position for now.

　Paaaaaahhhh ......☆

　The damage done to the enemy is still minimal.

　...... ...

　............


　Three hours later.

　How much did they hit each other?

　After attacking and recovering, recovering and attacking ...... repeatedly, they continued to inflict a little bit of damage, and finally the Green Dragon began to weaken.

''Oraaah!

　

　Finally, when the copper sword plunged into his gums, he suffered uncommonly and finally fell down.

　Dosun......

　Thus, the Green Dragon turned into a ball of light and passed through the underground ceiling.



　I'm tired.

　Anyway, let's get out of this dungeon with breakaway magic.


　Twinkle, twinkle, twinkle, twinkle!


Oh, there's Mr. Eigha.

Aega!

Mr. Eigha, how many floors have you been to since then?


　When I returned to the ground, the 'stranded party' that I had rescued earlier came running up to me.

''Never mind that, give us the items you've been entrusted with that you've acquired.

Oh, I'm sorry.

This way.

　Thus, when I am getting the items acquired from them back.

'That ...... Mr. Eiga Janies.

　I turned around to see that it was the lady at the reception desk of the sub-branch.

I'm sorry. I'm sorry I said earlier that I wasn't very strong at .......

Hey, sweetheart. What's going on?

　'What do you mean?' asked one of the deadbeat party members.

'I just received a report ...... that Eiga-san has reached the tenth floor underground and has beaten the dungeon boss.

Na!

The boss in here is a green dragon, okay?

And all by yourself?

What a guy. ......

　The adventurers in the area who are in an uproar.


　d*mn it ...... shut up.

　I got a little annoyed.

Just go! Don't be long in giving me that prize you've been working on!

　I yelled at him.

'Ha, yes (sweat),'

Now!


　Kacha Kacha, Kacha Kacha ......


　I strap the items I've acquired to the Black King Maru and step into the stirrups and quickly become a man on horseback.


''Hey, Eiga-san. Eiga-san, why are you in a bad mood? We even beat the boss.

Come on.

　I heard a whispering voice behind me, but I let the horse run on.
