"No, and the Atmosphere is amazing. I never thought I'd be able to use it like this."

"Here you go, boy."

"That's right, old man. Now Vulcania is a new, 8-km square city surrounded by walls 50 meters high. Besides, the Atmosphere will have acquired the defense of the Iron Wall."

"Hmm? What do you mean? By the Atmosphere?

"Oh. I told you I tamed the land with the magic of Atmosphere, the labyrinth nucleus. That means that the Vulcanian walls and things have become part of the labyrinth. So, maybe, but the Atmosphere works to auto-repair those things."

"... Huh? Auto repair? What do you mean, kid? You gonna fix the wall on your own?

"That's right. I mean, I worked for the Atmosphere to be like that. I asked him to fix it with the magic of the Atmosphere if the walls and sewers collapsed or broke."

"Oh, come on, that's true. I mean, can you even have a conversation with that giant rock..."

"No, because that atomosphere was said to be a spiritual stone. I've always wondered if I could make a deal with the Spirit like Kyle. Every night, he touched the Atmosphere and sent magic to try to have a conversation."

"Heh. So, you could even talk to the Spirit?

"No, I couldn't. But I noticed when I was sending magic to the Atmosphere. I'm manipulating magic like this urban expansion to trap Balkanian land. And it kind of feels like it, but this time I asked him if he could fix it automatically if he broke a wall or something that he built, and apparently, this is what happened."

"Hmm. It's a bit of an incredible story, but I guess that's what a kid would say. There will be no one but the boy who can use the nucleus of the labyrinth that far."

"Ha ha. From now on, you can call me Dungeon Master, old man."

Atmosphere is so great.

The amount of magic contained in the atmosphere was increasing just because it was there.

For this reason, at first I thought that there would be more people in the land with a lot of magic in the future just because the Atmosphere is in Vulcania.

But that wasn't the only effect of the Atmosphere.

Over time, Atmosphere's magic power didn't just penetrate the atmosphere, it penetrated to the ground.

And I realized I could use that magic by dealing with the Atmosphere every day.

He is responsible not only for this urban expansion, but also for its maintenance as the nucleus of the labyrinth.

This is true for my senses, but I also tried to actually attack the wall deliberately and collapse some of it to confirm it.

As a result, the collapsed walls had been repaired on their own over time.

Somehow, isn't this genuinely labyrinthine?

Maybe the fact that spiritual stones are mined in Atmos is because Atmos warriors appreciated and worshipped spiritual stones.

There is no certainty at all, but does it feel that the spirit stone could have been mined because there was an atomosphere in Atmos, and that the subject was replaced by a hardened brick in Vulcania?

One of these days I dream that the outer walls of Vulcania will make me look like an indestructible object of a dungeon like it's a story.

If so, you must be able to make a name for yourself in history as a fortified city with absolutely no offense.

"But then you can use it in other ways, can't you, kid?

"What, other uses? Have you come up with anything else on how to make use of the Atmosphere, old man?

"Oh. I'm not sure how it works, but anyway, I guess that means the kid made that wish come true because he wanted Atmosphere to keep repairing the wall, right? Then I thought you might want to do me another favor."

"What other favors? I wonder if I have a good favor to ask."

"If the walls fix on their own, how about you always want to keep the same nutritious land as when you [soil improvement]? A small area in the Balkans is fine, so if you have a land where abundance has been promised, you can self-sustain your food even if there are things like cages when you have to?

"... I see. Even if you don't use magic, you mean whether you can continue to maintain as much soil as you did after [soil improvement]. That might be interesting. Then let's do that with some of the Atmos district and the ranch district"

My old man came up with some pretty funny ideas.

If you have the ability to fix walls on your own, does that mean it's not weird to have the ability to undo the state of the soil on your own?

The ranch district is currently grazing goats and valkyries.

This land sometimes has horns and grazing, and Valkyrie is doing [soil improvement] on their own so that Hatka can grow and feed it, and goats eat it too.

but if the nutritional status of the land can be maintained on its own due to the influence of the Atmosphere, it may be possible to do so without Valkyrie.

And we decided to try to separate parts of the Atmos district again and make it agricultural land.

This place could be like a food plant when it comes to things.

I'd rather not have such a future if I could, but I'll make sure I can be self-sufficient internally in case I'm going to cage in Vulcania.

Thus, the city of New Vulcania, where the labyrinth nucleus exists, gained an entirely new defense capability than ever before.
