When he settled down, it was already a little after noon.

Jin decided to go back to the village chief's house for lunch. Barrow's parents asked him if he would like to join them, but he decided not to because he had Erza waiting for him.

Then, Barrow, go and relax with your family.

With these words, Jin returned to the village headman's house.

"Ah, Jin, welcome home.

Erza greeted him at the chief's house.

She said lunch was ready.

"Okay. I'll go."

So, leaving Edgar to stay at home, Jin, Elsa, and Reiko went to the chief's house.

The tax collector, Fliks Becker, was also at lunch.

"Oh, Jin-dono, Erza-san, I'm sorry we could only prepare this for you.

Lunch consisted of boiled corn and bean soup and salad.

"It's so dry around here that we can only grow corn and beans," Frix explained.

Frix explains.

"The other day, with the help of the Guild of Magi Engineers, a deep well and a pump were installed, but they are not working properly.

"What?"

Jin recalls that when he and Reinhard had come to Shoro, the main road had been called .

"There is not much rainfall in this region, so the wells are deep. It used to take a long fishing bottle to build them up, but recently a <> has been introduced."

As I recall, we sold the rights to the deep well pump to the head of a mutual guild of magical engineers in Hatata called Coates-Lordite," Jin said, digging up his memory.

"Let's have a look, shall we?"

The pump that Coates-Lordite had made for him back then was not bad, but what about the pump in this village, which was probably a mass-produced product?

With this in mind, Jin approached them.

"That would be great!

The village head bowed to Jin without hesitation. Even though he did not know what Jin had created, he seemed to know what a "Magecraft Meister" was.

So Jin finished his lunch quickly and went to see the pumps with the village headman. Of course, Erza was with him. Frix, who was also interested in the pump, followed him.

"Here's the first one. There are two more pumps, three in total, but they are all out of order. ......"

He said that although water does come out, the flow has become thinner and it takes twice or three times as much time and effort as it did in the beginning.

The population of this village is said to be about 200. It is not difficult to imagine the wear and tear that three pumps must endure if they are used every day.

I tried to run the pump for a while, and confirmed that it was moving too heavy, but not enough water was coming out.

Let's take a look. ...... Reiko, I'm sorry, lift it up for me."

"Yes."

The village head and Frix peeled their eyes as they watched little Reiko effortlessly pull up a deep well pump that was more than 10 meters long.

"......Good work. ......Ah, I knew the sliding parts are worn out."

Watertightness is of utmost importance for a pump that is subject to high pressure.

Jin concluded that this failure was caused by inadequate surface < and poor machining accuracy, which resulted in extremely poor durability.

"Elsa, do you understand?"

"...... yes, I understand the structure and principle."

Elsa, who came along with us, was familiar with ordinary pumping pumps and seemed to understand the structure of the deep well pump immediately.

To fix it.

The gaps are reduced to a minimum and the surface is hardened to prevent wear.

In addition.

The surface is mirror-finished to reduce friction and to make it more resistant to wear and tear, thereby extending its service life.

"That's it. Reiko, put it back."

The village leaders looked even more surprised when Jin finished the maintenance in less than five minutes.

Jin also applied and to the bearings of the pump levers to reduce some of the friction there as well.

"Well, let's see..."

He tries to run the pump by himself. The pump is lighter than before, and the water flow is better.

"This should be good here. Please show me two more places.

"...... Yes, yes!　Oh, this will help. Thank you!

The village head finally came to his senses and bowed repeatedly to Jin.

After that, he looked at the pumps installed in other places and found that all of them had the same symptoms. The work to be done was also the same.

Although we had time to go around the village, the repair of the three deep well pumps was completed in less than an hour.

"Sir Jin Nido, you have done a wonderful job. You are indeed a Magecraft Meister!

Frix, who had been silent during the three visits, suddenly became very talkative as soon as the village head pulled back.

"Well, I had imagined it when I heard about you at the technology expo, but you were far more impressive than I had imagined!

"Ha, ha."

"......I also wanted to become a magical engineer when I was young, but I was told I had no talent. I had already given up because I had already stumbled at the very beginning, but it is hard to forget old dreams, and I have become a hobby to look at the work of Magi Engineers. Sir's work was outstanding among them. ......"

Frix's self-talk went on and on, and just when I thought it was over, he started to ask me questions about magical engineering.

Elsa quietly left the room, but Jin could not.

In the end, they talked for more than an hour, and before they knew it, it was 3:00 p.m. tea time.

"Brother Jin, time for tea.

Erza called out to him, "Brother Jin, it's time for tea. Jin turned her down and headed away.

Frix looked like he had not talked enough, but he must have been thirsty from all the talking, so he went away to have a cup of tea himself.

"Thank you for saving me. ......"

Erza gave a sympathetic look to Jin, who was looking so tired that he was just about to plop down on the tea table.

"Thanks for your help. But it's like a tax on your fame.

"Even so..."

Elsa brewed us a cup of Perhias. Jin had brought it from the village of Kaina. Jin liked its light taste.

"Let's go check on Behle after this.

Read at https://w w w . m t l r e a d e r.com

"Yes."

Since they had heard that Behle's house was located on the northern outskirts of the village, Jin, Elsa, and Reiko headed north for now. Edgar stays at home again, just in case.

Except for asking the villagers once on the way, we were able to find Behrle's house without any hesitation.

It was really located in the outskirts of the village, almost in the middle of a wasteland.

It was a small building that looked more like a hut than a house, and the roof and walls were damaged beyond repair because it had been uninhabited for a long time.

From a distance, a figure can be seen inside the house. There is no mistaking it.

He was sitting on a broken chair, staring blankly outside.

Behrle's usually cheerful face looked dark and somber, so Jin decided to call out to him.

"Behle."

At the sound of his voice, Behle's body jumped.

"Ah...... Jin-sama, Erza-sama!"

Behle stares at the two with a surprised look on her face.

"How did you end up here?"

"Well, I was worried about how Behré was doing.

Jin tells the truth.

Read at https://w w w . m t l r e a d e r.com

"Oh, you're worried about me?

Behrle is even more surprised.

"Of course you are, aren't you?　Behrle is a very important worker in our company.

"Thank you for ......."

At Jin's words, Behré turns his head slightly and thanks him.

As you know, this is my family home. I had parents and a sister, but they died at the same time due to illness.

Read at https://w w w . m t l r e a d e r.com

Behle is the only one who survived.

As far as I have heard, it was some kind of epidemic cold...... flu-like illness.

There were many others who died, but the worst was Behrle's family.

Jin thinks that one mistake can be a big problem, because there is no idea of prevention or disinfection.

(Like here, we should be careful not only in Kaina village ...... but also in the neighboring village of Toka.)

) The land is arid to begin with, so if it is influenza, it can easily spread.

Jin wondered if something needs to be done.
