Currently, it was said that the octopus-like monsters had overflowed from the Sides Cave and were now heading towards the city in a horde.

　As soon as they received the report, the guards began to move briskly.

　Some rang the bells with a can-can-can to announce the state of emergency, others headed to the armory with their colleagues, and others headed to the Adventurer's Guild to ask for help - all of them.

　In the midst of a major crisis, none of them panicked and did their part to protect the city.

　I can't stay bonkers, either.
　I heard that the monster was created by an ancient civilization, but I need some more information.
　I asked Charu about it and this is what he said.

'I don't know much about it either, but I think it was called the Devilpath.

　Devil (devil) + Octopus (octopus) = Devilpath .......
　In a way, it's an easy name to understand.

The Devilpath is a magical creature created for counter-disaster and has a powerful self-regeneration ability. A cyborg?　And if there's anything left of it, it will be back in just a few seconds or ......

　I guess that's what cyborg ...... cells are for.
　Wouldn't it be too cheesy to be able to regenerate your entire body from that level?

''So the devil path is immortal?''
'No, there must have been a limit to the number of views. One of the developers was an acquaintance of mine, and he said, 'It's easier than defeating a high-ranking undead', so .......
"Easier than the high-ranking undead, or .......

　When I heard those words, something flashed in my mind.
　In my battle against the Great Sage Mobius, I defeated a large army of undead.
　Dullahan Lord, Elder Rich, and Wyvern Zombie .......
　All of them have passed the danger level A rank and are designated as S rank.

　The souls of the undead were all stored in the item box by my [Soul Absorption], every single one of them.
　Using the dark magic Necroearth, I can summon them at any time.

　...... Let's try using the undead this time.

　I use 【Auto Mapping】 to quickly check the map of the surrounding area.
　This area is just the knees of the royal capital, so there are a number of city roads running through it.
　It's not good to use Destroy Golem to reap everything like the last battle.
　It feels good to blow up the enemy, but it's going to cause a mass production of burnt out areas and craters.
　The monster could be defeated, but if the roads collapse and the royal capital is in an economic crisis ...... you can't be responsible for the situation.

　Of course, if we have no other means, we won't quit moving the mechanical dragons as well as the black dragons, not to mention the Destroying Golem, but we can bump up a large army of undead first.
　Then, just to be sure, I'll have to deploy the Guardian Golem and protect the city with wards.

　As I was thinking about this, the guard chief called out to me.

''《Dragon Slayer》Dono, may I have a moment, ......?
Yeah, I'll be fine.
'I'm very sorry to be so rude to you earlier, but would you be willing to help in the defense of the city ......?

　Rude?
　What the hell am I talking about?
　...... Oh, I remember.
　I remembered that when I caught a mercenary guild leader in this city, the guards mistook it for a fight.
　It was too small of a trouble, so I had forgotten all about it.

''Chief Guardsman, don't worry about what happened earlier. The misunderstanding was quickly cleared up, and in the first place, it's proof that the guards are doing their job properly that they are rushing to a fight in the back alley.
''Oh, thank you. ''You have a big heart, [Dragon Slayer] lord, ugh, my tears. ......''

　No, no, no, I don't want you to cry about this .......
　I'm not sure what kind of hardships the chief of the guard has to go through on a daily basis, but this is an inn town by the royal capital, and since there is a lot of traffic, there are probably a lot of complaints and problems.
　I want you to live strong.

''Anyway, I'll help you defend the city. You can rest assured. ...... or is it just about defense?
What?
I have an idea. Listen to me.

　* *

　This city ...... Fife is a reasonably large city, but by placing the four Guardian Golems in the north, south, east, west, and north of the city, they were able to completely cover it with wards.
　The wards have even played off the black dragon's fireballs, and this would be a perfect defense.

　Now we'll leave four Destroyer Golems as a fighting force, just in case.
　I decided to leave the command of a total of 8 units to Iris for now.

"Hey Ko, do you think I'm going to be staying at home?
'If something unforeseen happens, be flexible. Iris is an A-ranked adventurer and she's trustworthy. You're in good hands.
"Yeah, yeah, I get it. I can trust you, ....... That's nice.

　Iris gives an embarrassed smile.
　A short distance away, Lily and Charu said, "Iris-san is being rolled ...... by Ko-san. It's a colo-colo ......" and "Iris-chan, you used to be so crisp ......" were muttered.

　On a side note, at this time I was activating the 【Brave Person】 skill.
　This is because the people in the city were in a bit of a panic.
　Since the city is in danger, well, it's only natural.

The [Brave] skill brings about positive changes in people's minds depending on what they say and do while it's active.
　According to what I heard later, after I used the Guardian Golem to set up a ward in the city, the residents seemed to have gained a great sense of relief and the panic was put to rest.
　It's quite a useful skill, 【Brave man】.

　Aside from that, as soon as I finished my preparations, I headed to intercept the Devil Pass.
　I left Iris and Lily in the city and let Charu accompany me.
　When the battle is over, I'm going to go straight through the cave and ride into the underground city.

''Ko-sama, can you tell me more about that golem after the battle is over?
'You mean the Guardian Golem and the Destroyer Golem?'
'I was involved in the development of the Orihalcon Golem 5000 years ago. I was really interested in how Master Ko modified the golem: ......

　Charu is quiet and literate, but apparently she was a science girl.
　This is a bit unexpected.
　If that's the case, I'd like to hear all kinds of stories on my own.
　It would be interesting to hear the secret story of the development of the Orihalcon Golem.

　Well, anyway, it's after the battle is over.
　First, let's check the enemy's position.
　I activated 【Energy Radar and Convergence】.
　Since I'm level 91, 91 x 10 x 4 = 3640m.
　Although the range is limited to the front, it is possible to search for enemies up to 3.6km away.

The results of the search for the enemy were displayed in a flash on the [Auto Mapping] map in his brain.
　The swarm of Devil Pass was closing in on them at 1km away.
　There didn't seem to be that many on the scale.
　It was roughly estimated to be around a thousand of them.

　However, devilpas have the ability to self-regenerate.
　In that sense, they might be one of the most troublesome.

　After leaving the city for a while, I saw a creeping shadow in the distance.
　Not just one, but two, three, four--.
　They were crawling on the ground, approaching us.

''Ko-sama, they're coming!

　Char speaks up.

'That's the Devil's Pass!
Okay. ...... Okay, let's get started.

　I open the item box and select the Diabolos Armor.
　A jet-black, disastrous armor appeared.
　The added effect, 《Darkness King S+》, is activated, and my aptitude for dark magic is raised to the extreme.

Using the [Sage] skill's no-chanting, he tried to activate Necroearth while remaining silent.
　At that time, a voice echoed in my brain.

''Specific conditions have been met. The [Creation] internal sub-skill [Magical Evolution] will be released.''

　I was surprised.
　I didn't expect a new sub-skill to be added at this time.

【Magic Evolution】, as the name implies, seems to be a skill that evolves magic to a higher level.
　However, the magic that can be evolved is limited, and the magic from which it evolved needs to be used several times.

　Necroearth's evolution condition was three activations, and this was already fulfilled.
　Since it's so important, I'll make it [Magical Evolution].

''Dark Magic Necroearth has evolved into Dark Magic NecroDark.''

　The earth has changed to dark.
　In terms of characters alone, it only differed by two letters, but its effect was greatly improved.
　In Necro-Earth, the body of an undead was made from earth, but in Necro-Dark, the dark magic was materialized as it was.
　As a result, its body seemed to be much more enhanced than normal.


　　

　Alright, let's try it.
　I activate the Necrodark.

　Then, an abyss-like darkness spread out around my feet.
　An ominous presence is in the air, as if it continues deep into the underworld.
　The range was quite large.
　Perhaps a radius of about 100 meters.

　One after another, armies of the dead crawled out from the depths of the deep darkness.

　...... When I think about it calmly, I'm not very brave right now, am I?

　I feel like leading a horde of undead and fighting them, or rather the word demon king is more appropriate.
　Apparently Charu was thinking the same thing as I was, and spoke to me with a surprised expression.

''Ko-sama, did you also acquire the [Demon King] skill ......?
No, I don't have one.
It is ....... It's a good thing that you're able to get a good idea of what's going on in the world.

　I see.
　It seems that Char is the owner of a middle-aged mind.
　At first I thought she was a quiet and quiet woman, but her unexpected side is coming out more and more.

　I'd like to chat with her a bit more, but the situation is the situation.
　Let's take care of the Devil's Pass.
