Mertze and Goose were also asking around in the village.
The first thing they did was to talk to an elderly man who was introduced to them by the village chief.
He said, "If you don't mind, I'd be happy to tell you about this old man's story.
His name was Yoritoshi, and he appeared to be in his early 80s. He was tanned and dark-skinned, but he still seemed to be strong on his feet and legs.
"Now, please tell me about the old days in this village.
Guth spoke in simple language.
"Yes, well, I would like to ......."
According to Yoritoshi, this village was originally a collection of people.
It began with my great-grandfather. In the name of pioneering, three or four men from neighboring villages gathered here.
Ha-ha-ha.
Guth felt that it was a kind of "cut down on the mouths", but that is what it was.
And his great-grandfather, in other words, his grandfather's grandfather. Guth estimated that one generation would be 25 to 30 years old, which would mean that this village was established about 10 to 30 years ago.
And it coincides with the period when the <> was in power. ......, but that would be irrelevant to this region, he said.
"But there were people who lived here long ago. They settled here again after the village was abandoned.
Oh, is that so?
That's right. I heard that the buildings were still standing and with a little work they could be made livable.
That must have made it a little easier to move here.
"It seems so. After that they found a tree called yunos growing on the land and decided to cultivate it.
Ah, the yunos originally grew wild here?
That's what I heard.
And you have been breeding, or rather selecting, them up to now?
Yes, that's right.
I heard so, and I was able to listen to some useful information.

Now, Elsa.
She is strolling around the village by herself due to the assignment, but the old man is watching over her with a <>.
Elsa proudly calls herself <> (though she does not claim to be a court-appointed healer (Reichsdoktor)), and she and Nona, the wife of the village head, visit the houses and examine them.
"Thank you, Miss Elsa.
"No, this is also the role of a healer (doctor).
In such a remote area, there are no doctors or healers, and people rely on folk medicinal herbs.
Therefore, Elsa's examination and treatment was a gospel for the villagers.
(......After all, many of the symptoms seem to be caused by excessive calcium intake.)
Hypercalcemia and urinary stones were observed.
However, most of them looked healthy on the surface, so I took out pinpoints by <> without telling them, and then I tried to adjust their physical condition by <>.
"Erza-sama, are you all right?"
Nona is worried about Erza who uses healing magic continuously.
"I'm fine. At this pace.
At any rate, Erza was planning to examine about 200 villagers on this day and the next day over a two-day period.
Meanwhile, Jin and Goh were discussing the idea of making a to remove the mineral content.
"What if we make the container flat?
"It's not bad, but it won't be easy to use."
"Yes, ......"
It would be difficult to find a place to put it.
"I think it would be better to improve the efficiency of the magic circle.
"I know it's a bit of a power move, but I think it's the way to go."
In short, all you have to do is to set all the water in the water jar to be targeted.
The magic circle must be set up properly so that the hand that tries to draw water will not be deprived of minerals.
"Also, I thought of a magical device that would absorb minerals when submerged, but the running cost would be ridiculous."
"That's right. ......"
By thinking together with Jin, Goh learned a little about how to think about <>.
(I guess Bina is the leading authority when it comes to civilian products.)
She was once a friend called <> in the Egelea Kingdom of Bluerand.
She is now working for Hale, and is part of the planetary development team.
(It would be nice to have him help us with the development of civilian products once in a while...)
"...... Jin-sama?"
"Oh, sorry. I was thinking about something.
I drew a magic circle. Is that okay?
"Here you go."
Jin checked the draft of the magic circle that Goh had drawn.
"Yes, it's good. It is well done.
"Thank you very much!"
"Now all we have to do is to carve it into a quartz plate ......, which is too expensive, into glass, and it will be finished.
And then we can put the strainer in the water jar, right?
"Yes, yes."
The structure consists of a water bottle and a glass plate engraved with a magic circle is sunk into the bottom of the bottle.
A strainer is then inserted along the inside of the bottle.
In this way, the separated minerals are trapped.
"What?
What's wrong?
"Jin-sama, why don't you make a container out of a strainer and put a glass plate engraved with a magic circle inside it?
"Oh, that would require a smaller strainer, wouldn't it?"
"Yes."
Yes. That's a good idea. Yes, that's a good idea.
And so, by the hands of Jin and Goh, a magic tool of the magic circle type that softens hard water was completed.
Since this magic tool was applicable and inexpensive to make, it would later spread to many countries, and Goh would earn money from it as a technical fee (like a patent fee), but that is a different story.
That night, Jin and his group reported their results to each other and were satisfied with the outcome.
