Chapter 7 [The Cave Mechanism of Leveling Up]

Since returning from the cave to the apartment, my body has strangely been in good condition. It's not a bad thing, but I wonder what the cause is... Let's brace myself and try to appraise it.

[Individual Name] Nagayuki Karasumaru

[Species] Human? Dungeon Core? Dungeon Master?

In the shock of moving from another world to this one, he coincidentally fused with a Dungeon Core. The skills gained were few due to the immature Dungeon Core, but as a result of repeated movements, his body accumulated immense distortions, allowing him to possess extraordinary magical power. However, at this point, he hasn't acquired magic skills related to magical power release, so the use of magic is limited.

[Status] Dungeon Aberration

[Level] 4

[Unique Skill] "Broken Dungeon" Level 2

He can set up a dungeon within a fifteen-meter radius of himself. The size of the dungeon that can be set up depends on the level. Additionally, he can instantly move within the dungeon he set up. By setting a Dungeon Gate between dungeons he created, he can freely move between dungeons. He can arbitrarily change the internal structure of the dungeon.

[Skills] Language Understanding, Appraisal, Subordinate Magic, Familiar Strengthening, Telepathy

The level is increasing without doing anything. It might be because of traveling between worlds, but I feel like that's not the only reason. Thinking about the level up of my child - the familiars - the suspicious thing is the boar I ate over there. If they level up by eating things from Earth, maybe I'm leveling up by eating things from that world. If that's the case, this is a significant advantage. I'll diligently have meals over there and focus on leveling up.

In that case, let's prepare some seasonings. I should have "sugar, salt, vinegar, soy sauce, miso." Miso is troublesome to store, so instead, I'll bring spices like pepper to the other world. With just these, meat should taste delicious.

...

Now that I've understood the mechanism of leveling up, I should investigate my skills. Regular skills seem somewhat straightforward. The issue lies with the unique skill, "Broken Dungeon."

Moving dungeon walls—I tried that during the Keen boar incident. What does it mean to be able to set up a dungeon around myself? I can't test it inside the cave over there—it seems it's already become my dungeon. Trying it out in the apartment is also risky. Whether magic works on Earth, its effectiveness, and if it matches the power in the other world—all these are uncertain. It would be troublesome if someone saw or noticed.

I might have to try it after leaving the cave in the other world... or not?

When I focus my consciousness deep within, the nature of this skill vaguely comes to mind. Essentially, a dungeon is a magical accumulation, and a dungeon seed germinates and grows with magic, creating it. The seed transforms the surroundings into a dungeon using its magic, and the grown seed becomes a dungeon core. I, ignoring the conditions, can construct a dungeon even in an imperfect form. Ah, that's why it's called "Broken Dungeon." To construct a dungeon in its perfect form, you need both skill level and magic, but for an imperfect dungeon, you can create it with a low skill level and without consuming magic.

However, what's the use of an imperfect dungeon... wait.

Oh, I tried it on a whim, and I could generate dungeon walls here too. I used potting soil as a material, and it looks just like dungeon walls. If I can freely shape this and... yes, it worked. A knife made of indestructible dungeon wall. No, no, no, no, this is not a joke.

...Let's calm down a bit. Put this back into the soil to erase the evidence. Yeah, there was no dungeon wall. It's just my imagination.

Moving between dungeons is a skill used by Dungeon Masters who dominate multiple dungeons to move between them. Do they open something called a Dungeon Gate? If I can use this skill even with an imperfect dungeon... can I use it to leap to a place marked with an imperfect dungeon? In essence, if I mark a place I've been once, I can move there instantly at any time. It's convenient, but the initial first move is the drawback.

This skill seems quite useful. Since it might become my lifeline, I want to level it up as much as possible. Based on what I read in light novels, repetitive practice seems to be the best way to improve a skill. Let's aim for skill improvement by using it as much as possible. I'll rely on meals for increasing magical power. Bring seasonings, spices, and cooking utensils, and let's ravage the meat and nuts over there. Well, let's try various things anyway. This is exciting.
