Jin wondered how he could expand the conversation with the shy Maitreya Kouno.

He decided that it would be a good idea to talk about his field of expertise.

"So you decided to make that filter because you were concerned about the taste of the water?"

"......Yes, yes. ...... We had a hard time with water, too."

"Is it your gastrointestinal condition?"

...... yes, yes, yes.

"Yes, yes." "Apparently, the water here is too hard."

"...... yes, it is. is not suitable for cooking. ......

"I understand."

"......, there is a lot of < in the water, and it does all kinds of bad things to you. Especially too much magnesium can cause diarrhea. ......"

"I see. That's why you installed the filter.

That's right.

How the hell does it work?

Jin sensed that Maithey's tone was becoming a little smoother, and asked him about a technical topic.

"It's not that difficult. ....... Many of the minerals are larger than the water molecules, so you can filter out a percentage by passing it through a fine filter."

"Haha....... But if the filter is too fine, won't it slow down the flow of water?" "That's right.

"Yes, that's right. That's why the filter inside the filter ...... is folded up in a bellows style to make the surface area as large as possible."

"Ah, I see."

"Although it only removes about 10 percent at most at a time, it's better than nothing."

I see.

Well, then we run it through the same filter again to reduce the mineral content by another 5 percent or so.

Oh, you mean it's double-layered?

Yes, that's right.

Yes, that's right. That's great.

Jin praised the fact that they had achieved such a great effect without using magic, but only a physical structure.

"Thank you very much. Just the fact that there is someone who understands it makes it all worthwhile.

Maitei Kouno smiled happily.

He seemed to have gotten to know us a lot better than when we first met.

Then, Maithei's automata came to him and reported.

"Mr. Mighty, I put the buckwheat powder in the car.

"......, MS-081, thank you very much."

Are you Mr. Mighty's automata?

Yes. Yes. ...... but I didn't make it.

No, Mr. Mighty designed the basis of my control core. He also designed the external appearance.

"Well, yes, that's true."

"You speak fluently and move smoothly."

At this point, the automaton thanked Jin.

"Thank you very much for your compliments. My name is MS-081. May I ask your name?

My name is Jin.

Jin-sama, is it? Are you a magical engineer, a MagiCraft Meister?

"Yes, I think so.

Jin is not lying, as he holds the first generation in high esteem.

"Do you also make things, Jin-sama?

"Of course I do.

"I see. Then it is only natural that you and Mr. Mighty are in agreement.

Jin imagined that this MS-081 seemed to know that Maithei was shy and was happy that he was able to talk with him. (If that is the case, then the control nucleus

（If that is the case, the control core is quite good.

(If that is the case, the quality of the control core is quite good.

Jin guessed that it was about the same level as the first five-color golem maids.

Jin then asked her about it further.

"Are you a collaborator if you didn't do it yourself?

"Well, yes.

"Well, yes," he said, "You must be a good person to have shared the workload and overseen ...... all this.

Do you understand?

Do you understand? I think it's not easy to coordinate highly skilled technicians and create a well-balanced work.

"Thank you."

Mai-Tei is as pleased as if it were her own.

Jin and Maitay continue their conversation: .......

* * * *

Watching from a distance as Jin and Maitrei were talking happily, Reiko remained vigilant.

However, she had already confirmed that there was no danger in this village.

However, she was on the alert just in case.

After all, she could not go near Jin now.

If I do so, Jin's true identity may be revealed. .......

But then, the old man gave me a word of advice.

"What is it?"

"Pretend that you are imitating .

"In other words, you want me to to be an automata, a follower of the Magecraft Meister?"

<. I guess Reiko can call herself here.

"...... with the power reduced to the limit, of course?"

<<

"But the village chief sees that I am acting as a human being.

"Yes, sir."

Taking the old man's advice, Reiko goes to Jin's side.

"Father, do we have a visitor?"

"...... Reiko?"

Reiko went to Jin and Maitai's side.

Then, following the old man's advice, she introduces herself. .......
