Jin D., Alto Elbein, and Nahams Marrow came to the reservoir.

"Well, this is a nice reservoir.

The pond was almost full and filled with clear water. The kids had gone home and there was no one around.

"Well, I'll have to make some modifications to the surroundings to make it less dangerous.

Jin thinks about what would happen if he fell into the reservoir.

"It would be the most dangerous thing if I can't crawl up.

The current reservoir is almost vertical. It is like a deep pool.

"So you want to make it slanted?"

Nahams Marrow asked Jin D., who was following us.

"No, because if there is moss on it, you might slip and not be able to crawl up.

Even in modern Japan, the dangers of sloping reservoir banks had been reported.

"...... should we make it a staircase shape even if it is troublesome here?"

If it is a stairway instead of a slope, it will be easier to come back up if you fall into the water, and safer if you need to fetch water.

"It's going to take a long time."

Alto Ervine said,

Jin D. replied, "Yes, ...... well, it is still light.

Jin D. replies,

"<><><><><><><>>......"

<> was exercised in succession.

"Oh, oh, oh!

"Oh, my God!"

Jin performed a series of digs, changing the size of the digs slightly. This made the shoreline look like a staircase.

Of course, this is a precise size adjustment made possible by a <>.

"This should work."

The overall angle is about 30 degrees. The width of the tier is about 30 centimeters, and the height is about 18 centimeters.

This way, you would not be unable to climb up from the shore, and you would be able to fetch water.

It would also be safe to play in the shallow area because the water would be the same all the way to the bottom.

"Now all we need is a fence."

In a vacant lot about 30 meters away from the reservoir, there are about 10 pieces of wood. They are the remains of a bridge over the drainage channel.

"This is to be divided into ...... and . "

"Oh?

What?

One square timber 4 meters long and about 20 centimeters square was instantly divided into 36 square timbers 1 meter long and about 6 centimeters square. It was divided into 36 pieces.

"You need a railing too. ......<>"

Now it was divided into 9 pieces of 4 meters long and 6 centimeters square.

"......"

"............"

"Well, it's too much trouble to do the math, so let's just stand these up as we see fit."

For today, it's just a temporary fence to prevent danger," Jin D instructed Reiko and the ten > that had been standing by ...... some time ago.

> hammers 1 meter long square timbers.

Reiko uses a 4 meter long square timber as a horizontal pole to put a fence around the reservoir.

The work was finished in about two minutes.

Of course, there are some gaps in the fence, but it is enough to warn people who approach the reservoir.

The missing part will be done tomorrow.

At least the danger of falling into the reservoir and not being able to climb back up has been greatly improved, Jin D. decides to go back.

Before he knew it, the stars had begun to twinkle in the sky.

"I'm sorry for the detour. Let's go home then. ...... what's that?"

"......"

"............"

Nahams Marrow and Alto Elbein were frozen when Jin called out to them after finishing his work.

"Let's go home, shall we?"

Jin D. calls out a little louder, and the two reactivate.

"Ah, ah, yes, yes."

".................."

Alto Elbein was still exclaiming.

The <>10 were instructed to stand by the reservoir and to be careful to avoid any accidents.

* * * * * *

After that, nothing happened and Jin D., the three of them and Reiko returned to the village chief's house.

The dinner was just about ready, and they enjoyed chatting with each other.

"......, so I'm going to put a fence around the reservoir."

Jin explained to the mayor that it would be dangerous if a child fell in and drowned.

"I see. Most of the people in this village can't swim. ......"

Even in a country with an ocean, people do not learn to swim unless it is closely related to their daily life as fishermen do.

This is different from the village of Kaina, where the Erme River was located, Jin D. thought.

"Do you want to set up life-saving equipment in the reservoir in case of emergency?

"Life-saving tools?　What kind of life preservers?

It's a float with a string attached to it.

"Oh, I see."

* * * *

Alto Ervine was listening to and analyzing Jin D's story, while listening to the conversation.

(Reduce the danger of reservoirs: ......?　Why go through the trouble?　I thought ......, but since it only takes that much effort, it's no wonder they did it. But ......)

And at the same time, I was confused.

(...... save a drowning ......?　Do we bother to help those who have gone into that danger themselves ......?)

Having received an elite education as a secret agent in the Principality of Jagus, Alt-Elbein is a man who takes the consequences of his actions into his own hands.

(You call that helping ......?　What is the point of saving the inferior species by interfering with selection ......?)

One of the typical examples of education narrowing one's thinking and narrowing one's vision was Alt-Elbein.

Unsure of what to think, Artoo decided to ask Jin D.

"Jin-san, can I ask you a question?"

"Huh?　Uh, yes, what is it?

"...... well, I don't know how to put it."

This is a preamble to a straightforward question. If you say this, even if you ask something a little strange, they will often overlook it.

"What is the point of going out of your way to help someone who has been in a self-inflicted accident?"

"......!"

Nahams Marrow frowned a little when he heard this, as did Ike Nibiki, the village head.

But not Jin D.

Now that the old man was in control, he knew exactly what the question was about.

（<)

And I'll try to give a response in line with such an intention.

"I see, <>. Is that what you like to do?"

And Alto manages to respond to this response.

"Yes, yes, that's right. I like to think about . I think about them when I'm on the move, to comfort my ennui."

"I understand."

This exchange seemed to satisfy both Ike and Nahams, and their faces became less grim.

"Yes, why don't you help us ......".

The old man then let Jin D utter an unusual answer: .......
