Dungeons for the Devil, Dungeons for the Core (Book Version Title: A Different World Dungeon Made with the Devil)

"Infrared photos..."

What Christmas City suggested was how about detecting the heat emitted by an object (infrared) and creating a heat distribution map. If an area with high emission calories is viewed as an area where human activity is active, the degree of human activity can be seen from a heat distribution map superimposed with the map. In the Earth world, infrared imagery was obtained by satellite or aircraft altitude shooting, but we can fly Christmas City here, so there's no problem there. The problem is...

'But... where do you procure infrared cameras from?

There is no such thing as infrared cameras in this world. Well, it's not that easy to get in the Earth world either. No, to be precise, it is not impossible to obtain a handy-sized one, but it is not something that can be used to obtain thermal images from high degrees. The type for drone mounting has also been on sale lately, but at an altitude sufficient for drones for civilian use to be able to fly, the thermal images intended for crows are difficult to obtain.

"Isn't that admiral (admiral) dungeon magic and everything?

"... Oh, so you (Christmas City) were a dungeon too..."

A special example - there is no other example of a dungeon flying around freely and shelling itself against enemies outside the dungeon - so I tend to lose sight of it, but Christmas City is a historical (refreshing) dungeon whose exterior hits the walls of the dungeon. Beyond being a dungeon, it can be modified or enhanced with Crowe's Dungeon Magic, which is also the "ruler of the dungeon".

It was also due to this dungeon magic that we actually installed various sensors in the Odrant dungeon. If I think that the scanning content has just changed from visible light to infrared light, I don't think there's anything I can't do...

"Is there anything wrong with trying..."

A few days later, a family meeting had been convened over what Neil had heard at the Adventurer's Guild headquarters in Vinstadt and the results of the analysis of heat distribution images (thermograms) taken by Christmas City from over Theodoram, newly equipped with infrared cameras.

'... Hmm. The heat is stunningly low along the central street... maybe it's from the beginning. The West Street, by the way, is lively. Hasn't Vazari had much of a falling effect?

"Marcto is a thriving town in dealings with coastal countries. The volume of trade with Vazari, with the slave trade as its main axis, is not significant. In one way or another, Vazari would have benefited more. '

"So... compared to its West Street, East Street is more subtle. … there are several places where the calories are getting bigger… '

"This is the assembly point of the National Army."

"You mean it's not a commercial activity... don't match the results Neil's been hearing about."

An eye-raised crow from the heat distribution image (thermogram) confirms to Neil.

"Heh. I just heard on the guild that the east side stinks here, so more adventurers are leaving. Temporarily... it's a gold mine. They said there have been a lot of people flocking around, but since Isakoza with Marcus surfaced, there have been a lot of adventurers and merchants leaving town to avoid trouble."

"Is that why the town along East Street isn't vibrant?"

It was Crowe who made a point with......, but here the correction comes in from the peter.

"Ah, no, originally in the eastern part of the kingdom, there are not so many flourishing towns. Because only virtual enemies border the eastern border. East Street was originally built for military mobility."

"Yeah? Then what is it that Neil's been hearing, a runaway merchant?

"Perhaps, but not the guys who were doing business with Gregorum or Nicholam's regiment opponents. A state-appointed merchant won't just run away, but it's no wonder a small merchant will run away."

"You even talked to me about that little merchant move... sounds like you got a good head start"

"Sora already. When I twitched Wyburn's membrane, you just smiled."

He even spoke quite a bit of stepping in.

"So, I was just wondering..."

"What?"

"Heh no... they say the Yaltan ones are starting to rush into the anxiety of the people"
