In order to make Saichi a , Jin first installed 10 wells.

The pumps are for deep wells, so the water output is small, but it is much more convenient than before.

"Oh!　This is wonderful!"

The village headman, Ike Nibiki, was delighted to see Jin's skill.

The villagers, their initial doubts having been put to rest, were amazed and astonished at the excellence of the engineering magic and Jin's skill.

The fact that Nahams Marrow, whose face they knew, had assured them of the magic may have helped the villagers to get used to it.

"I guess that's about it for today.

We started around 2 p.m., so it's now 4 p.m. The sun is still setting, but it's not too late. There is still time before sunset, but there are still things to be prepared for.

"Thank you for your hard work, Mr. Jin.

Nahams Marrow, Undersecretary of the Minister of Technology, looked at Jin with a tired face. Jin looks unconcerned. It is hard to tell which side did the work.

I don't know which one of us did the work.

That was it for the day, and Jin returned to the with and flew out of sight.

Nahams Marrow decides to stay at the chief's house.

"...... Master Marrow, what kind of person is that Master Jin?"

Ike asked Nahams Marrow that night. No, I had to ask.

"Master Djinn. He is the greatest magecraft master of our time. In other words, the best maker in the world.

"Magecraft Meister ......"

You've heard of him, right?

Yes. ......

The village head had heard of the legend of the Magecraft Meister.

However, he still could not believe that it had appeared before his eyes.

That night, the village head was writing something.

It was on a very thin piece of paper, and the words were so small that they could only be read with a magnifying glass.

Twisting it into a thin twisted paper, the chief went to sleep.

* * * *

The next morning ...... around 5:00 a.m., the sun had just risen.

The sun had just risen, turning the area orange.

The village head got up, went to the aviary adjacent to his house, and took out a pigeon.

He tied a piece of twisted paper to its leg, which he had made last night, and released it into the sky.

No one noticed. No, there was one.

>.

He is the administrator of Horai Island and the world's greatest magic brain, the old man. <<

Since he is the person Jin will be in contact with in the future, I used the <> to investigate.

Then, he used a pigeon to contact somewhere.

By the way, I know what you wrote last night.

<<<>...... this was sent to ......>>

It is unknown because the pigeon has not yet arrived at its destination, but it is definitely flying in the direction of the Principality of Jagus.

<

However, considering that the village head is a spy or brainwashed, I decided to inform Jin.

* * * *

Jin is sleeping in a . He is sleeping in the because the day and night are reversed when he returns to Horai Island where the time difference is about half a day.

When Jin woke up and finished rinsing his mouth and washing his face, he received a report from the old man.

"......I see, the village headman. ......"

<>

"Well, if there's no harm done, let's leave it for a while longer. I'd like to know the reaction of the Duchy of Jags to the report."

<<>.

"Yes, ......, I understand."

Jin D., following the old man's advice, uses the warp gate inside the <> to move to Horai Island, and Jin D., using the <>, moves into the <> instead.

"Well, today's schedule is ...... and..."

We are going to install water and sewer lines to each house eventually, but since they are all pretty tired and will need to be rebuilt soon, the plumbing will have to wait.

"We should build a reservoir that can be used for agricultural water. And a settling pond."

A sedimentation tank is a pond to collect sewage once the sewerage system is eventually installed. The supernatant water will be treated so that it can be used for agricultural purposes.

Jin thought it would be a good idea to periodically dredge the sludge from the bottom and incinerate it or use it as fertilizer.

Well, whether it can be used as fertilizer or not depends on the composition of the sludge.

"Now all we need is a garbage incinerator."

Jin had hoped to eventually be able to use the heat from the incineration in some way, but first he would have to install one.

"It would be nice if we could dig a hot spring too. ......"

The strata in this area are so old that you have to dig quite deep to get hot water.

"First of all, we need a public bathhouse."

After considering these items, Jin D. headed for Saichi village under the guise of .

"Good morning, Mr. Jin.

"Good morning, Mr. Jin."

The village headman, Ike, and the vice-secretary of technology, Nahams Marrow, were out in the open and greeted Jin.

"Good morning, sir."

Jin greeted back,

"Have you eaten yet?

He asked him if he had already eaten. At the same time, he explained that he had already eaten.

Since both of them answered that they had, Jin D decided to get to work immediately.

"First, we need to build a reservoir for agricultural water. "Where would be a good location, Mr. Mayor?

"Oh, let's see ......, the southeast part of the village would be good.

The village head said, "This area has a slight slope toward the north, and if we are going to build a reservoir, we want it to be at the highest point.

"I understand."

The elevation of the site is not so high that it is difficult to fill the pond with water, since the slope slopes gently higher toward the south.

Since the difference in elevation in the vicinity was known from the topographical map, Jin D. immediately decided on the site.

"Let's choose this site.

Jin D. indicated a location on a gentle slope with a slight dip in the ground.

"Yes, that's fine.

"Then let's go to ......."

Jin D immediately used . This is originally an earth magic, but has been incorporated into the engineering magic.

"Oh, wow!

"Wow!"

A rectangular depression of 30 meters on the long side, 15 meters on the short side, and about 3 meters deep was created in an instant.

The gouged-out soil had been raised around the depression like an embankment.

Jin D further processed the inside of the depression with <>, sticking the soil particles together to prevent water leakage.

At this time, the <> is avoided.

"Let's put a sluice gate here. ...... Reiko, bring it here."

"Yes, I'll do it."

The reservoir is completed by attaching the sluice gate that was made in advance.

"Now we need to dig a channel from here. We'll fill it with water at the same time, and then we're done.

"Ha, ha. ......"

"......"

The village head, Ike, and the technical vice-minister, Nahams Marrow, were at a loss for words after witnessing the unorthodox work that had been carried out yesterday.
