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

In Marcus, who confirmed that the soldiers of Theodoram had jumped out of the dungeon looking excited, I then - thinking that it might work for a moment - tried a certain method that I was preparing.

The method worked surprisingly well, and Marcus found out that Theodoram had found water in the dungeon.

"... but you've done better than I imagined, lip reading"

"When one of the soldiers came to complain, I didn't think such a good thing would happen..."

"Neither do I. It's not like I made a fool of myself. You must report what you learn to your home country as soon as possible. … and the usefulness of lip reading."

Lip reading.

Techniques that, by reading lip movements, can infer the contents of a conversation to those who cannot hear or from a distance they cannot hear.

At Marcus' border surveillance unit, one soldier's petition - half-heartedly - was accepted. He arranged for someone with lip reading skills to "read" the conversation of the Theodoram soldiers.

They say lip reading is not as divine an effect as being eliminated in alleys (again). This time, however, it was relatively easy to read because the excited soldiers had repeated the same word over and over, and because the word and pronunciation - precisely lip movements - were few words similar.

That was the word "water".

Taken together, the hypothesis previously articulated by the deputy of the surveillance unit, and the results of the next lip reading procedure, these, it was easy to guide the conclusion that "Theodrum successfully procured water within the dungeon".

"I'm curious how Theodoram detected the presence of water... but now it's more about how getting water changes their policies than that."

"Do you think the policy will change?

"If I could have secured a sufficient amount of water. If we can secure enough water, and if the water shortage that has constrained their behavior so far has come off, yes, I think that's a great possibility."

When the deputy firmly played (cancer) with the words of his superior officer, he asked about the repeated words.

"You think the amount of water you get will dictate their behavior?

"On the contrary, it seems that we can also estimate the amount of water obtained from their actions. Well, this is just an idea, not a well-founded statement."

When he smiles bitterly at his deputy, who gives him a surprised look, the commander gets to the point of Xu (Omoro).

"Fly an expedition to the nearby villages. I've been going back a few days to see if there's been any change in the amount of water in the well... well, I'll be careful for the next two weeks or so."

The deputy appeared to be completely overwhelmed, but he nevertheless promptly carried out what he had been commanded to do, and then questioned the commander.

"Are you thinking about the possibility of an impact on the groundwater level?

"I may or may not answer. But if it does, you might be able to guess the groundwater flow by looking at which well it affected. Given Theodoram's future opponents, keeping track of the flow of groundwater may be a deciding factor."
