Is this it?

Yeah, it looks like there's another entrance, but it's the closest one.

The spirits taught me to dive in through the openings and then descend temporarily before Crowe's eyes.....

"... the inside is surprisingly large."

Ah, that's why Giddo is a candidate for the dungeon.

I thought so from Gid's story, but the cave in question looked like a cloister cave. --I dared to say no because Crowe couldn't tell if the rock quality was limestone... but it looked like a cloistered cave anyway.

And... when it comes to the belly cave...

In the river.

Ah, it's an underground river.

― ― It was a groundwater current.

(Hmm... if you look at the water flowing, is it a clock cave still growing? If it were the same as the Earth's clock cave, would there be karst topography on the ground?

Crowe checks the condition of the cave as he tries to check later.

There is so much groundwater flow that you will not be inconvenient to the water source, but on the other hand, the inside is slightly wet. It will be possible to modify it with a dungeon magic, but that could destroy the cavernous biological phase that is now in place. Crowe wanted to avoid it.

(... then... this is the main dungeon of the trap too?... No, wait... I don't think there was a human trail?

Also (in the first place) Crowe looked at this place as a candidate site for a new dungeon core. This is because there was an opinion that the new dungeon core was overloaded with various kinds of loads. Initially, the "Cave of the Hundred Demons" was a candidate, but it was impossible to entrust the eighty-seven hierarchical dungeon to the newborn paper, and the proposal was defeated. Instead, a dungeon monster named "Hundreds of Demons Cave" appeared in the cave.

I'm temporarily wondering if this clock cave is suitable for the core of the paper, and the other reason is....

(... I thought it would be a destination for Dungeon Monsters in the "Unreturned Labyrinth"...)

The "Labyrinth of Return" and "Labyrinth of Flowing Sand", which have been designated as dangerous dungeons, continue to be lacking in adventurers trying to challenge them for the moment. After all, dungeon monsters were also entrusted with the mourning of meat.

Recently, a Theodrum detective arrived, so we succeeded in removing gas by conducting field tests using them, but it has not yet reached a fundamental solution.

So - I was thinking of building a new dungeon as a place for dungeon monsters....

(... if you're in a place where humans don't come, your plans are suspicious...)

If you succeed, you may be questioned about your management skills as a dungeon road.

(But... why is there no human trail?

According to the knowledge of Crow Marunagayuki, ancient caves have been used as dwellings for humans and animals, as hidden places. There is also plenty of water here. Temperature changes should be small in the cave. It's not a difficult environment to live in, is it?

Crowe, who was suspicious, asked everybody,

"Well, Crowe, I don't think people usually live in mountains. Mountains belong to monsters.

Sure, it's fascinating to have water... but the humidity is too high for the base, and it seems bad for the health of the soldiers.

If you don't go deep enough to use it as a campsite, there's no flat space.

Extremely...

"There's no such thing as a drunken adventurer diving into a cave that's not a dungeon."

It was Grandpa's point.

Although Crowe did not seem to know, it is said that only near the entrance of the cave were the caves used by cavemen in the global world, and there are few examples of using the back of cool and humid caves as dwellings.

But then....

If you think this is a dungeon, why are the adventurers coming?

"... if you don't stretch out and make a noisy dungeon..."
