Goose gave several reports on his visit to .

"Battaghtarf and Dathe are completely deserted now. I was only there for a short time, but I didn't see any signs of life. And Naminthe, of course."

"I see. ......"

Jin wondered how things would change after the Shoro Empire's survey team arrived.

Perhaps it will be developed in cooperation with Mitsuho and Fusoh.

"Or perhaps a new country will emerge.

Guth correctly guessed what Jin had said.

"Yes. The old Newell has perished, but perhaps a new Newell will be founded.

"Yes. But it will be a long time before that happens.

"Before that happens, we need to let the public know more about Adriana Tierra ......."

That's my role as a , Jin thought.

"We have a lot of work to do.

Jin spilled out,

"Isn't it better than having nothing to do and having too much time on your hands?

Goose said to him.

"Yes, it is. ."

"What's that ...... thing?　I think I heard about it a long time ago.

"Yeah, it means that when you have too much time on your hands, you're a regular ......, no, a boring person who doesn't do anything worthwhile."

"I wonder if that's true. ......You may be right,......."

While I was talking with Goose, the old man reported to me.

"My Lord. Good. Is something wrong?"

"Yes?　Let's hear it.　......Yes, I'm going to the laboratory now."

So Jin went to the laboratory. Today the mini Reiko is lying on her head, not on her shoulders.

"Please."

First, a map is projected on the magic screen. The map shows the village of Toka, the village of Kaina, the Shama Marsh, Lake Manuse, and the capital city of Alban.

<

"Yeah. ...... Oh."

<

Still, a mesh of underground water veins is shown.

It seems that rain and snow in the northern mountains are flowing under the village of Kaina as subterranean water.

Some of them flow into the Shama Marshland, and some of them flow under Toka Village.

.

"Yes."

<

"I see."

The reason for the disappearance of the obvious water veins was not that the water had run dry, but that it had permeated widely.

"So, what's wrong with this water vein?"

<

Poison?

<

However, since it was about 150 years ago, all the ringleaders are no longer with us, and in any case, they cannot be held responsible.

<<>.

The procedure for spraying poison was simple, as the old man explains with some speculation.

Throw the poison into the wells at key points and expect it to flow away.

All the water veins that would spew the poison would be blocked, since the presence of the poison might be known in advance.

"So you stopped the spouting spring in the village of Toka, just before the village of Kaina. ...... Oh my."

Jin could not help but laugh at the ignorance of the leadership of the at that time.

The hot springs in Toka Village are pumped from far deeper than the water veins of the nearby wells and springs.

Otherwise, the geothermal heat would not be enough to produce hot spring water.

"I thought it was common knowledge that you can't master power without knowledge."

The <<<< Magic League>> never professed that scientific knowledge was not necessary as long as magic could be used. I think that they were working on such a foolish scheme without the knowledge of Markitas.

The old man is also very harsh.

"But what about the poison?　Wasn't there any damage?"

"......Ah, that's stupid."

>.

Jin and Laojun are both ...... no,

"They really are idiots,......."

The three of them, including the mini Reiko on top of Jin's head, were dumbfounded.

"So?　...... I kind of know the results."

<

"I guess so."

It seems that the hot spring in Toka village was drilled by Jin and the outlet channel was prepared, but it was a disaster, and once it was plugged, it stopped gushing from the other side.

"We built it well."

Jin learned that not only this, but also a water release channel or a safety valve structure should be considered in case of a blockage of the waterway.

Yes, there is always something to learn no matter how old you are. ...... Well, do you know what the poison was?"

< had used.

>.

"Was it aconite poison?"

Most of this knowledge comes from the medical books of Shuki Tsezi, who was a medical student.

<

In any case, there is no record of poisoning or any other symptoms.

"Okay. I guess we're done with this."

Jin decided that it was in the past and that there was no point in further questioning what had already been done.

"It's more about the future."

.

Jin told the old man,

"What about the bus we rented to the Klein Kingdom?

He asked. He is concerned about the reputation of his creation.

and have reported that it has been well received. The full-scale operation is still a long way off, however.

This is not surprising, since the full-scale operation will be when they carry tourists for the air race.

"But you're trying it out, hypothetically, I mean?"

<

"Well, I guess so."

No matter how good the performance and comfort of the buses are, it is Klein Kingdom that operates them, and it is meaningless if the arrangements are bad or if the customer service is poor.

Therefore, the old man explained that the buses are being operated on a trial basis as a means of short-distance transportation.
