May 14.

Jin and the others are hoping that maybe the people they are looking for will come.

So they stay close to the village and continue yesterday's activities.

Jin and Goh are fine.

"Oh, is this the magical tool that makes the water taste good!

"Yes, it is. Yes. All you have to do is to submerge it in a water jar. And once a month or so, a whitish stone-like substance called a skeil accumulates in this net, so please take it out.

"Okay."

"Oh, the skeil is valuable, so it is good to keep it.

Is that so?

"Yes. It can be a resource for light metals such as magnesium and calcium.

"I don't know about that, but if it has value, I won't throw it away.

And so on.

"Well, how much is it?"

"Of course, the mayor is staying with us, so of course there is no charge.

"That's not quite how it works. ......"

No, no, no, he's been very hospitable.

"Is that so?　...... but can you make more of this?

If you have the materials.

How much would it cost?

In that case, I'd say 300 dollars per piece, including materials. I would say about 300 Tall (about 3,000 Japanese yen) per piece, including the cost of the ingredients.

It is cheaper than the water purifiers that are commonly used in Japan today.

"Nah... ......!　That cheap?"

"That's what we believe."

"......Thank you. ......It is somewhat similar to those people, isn't it?"

"Those ...... are the technicians who come to this village?"

Yes. Yes.

Hearing this, Jin thought that he would like to meet them soon.

Saki and Rubina were in the village.

Saki and Rubina had come to the cliff on the north side of the village.

"In places like this, you can see what's going on underground without any trouble."

"Oh, yes, that's right."

"Look, this is interesting," she said.

"...... fossils?"

"It's a fossil of a mollusk."

A fossil of what on Earth would be called an ammonite.

"They used to say that the shells were turned to stone by magic.

Actually, it wasn't magic, it was just the years.

"But it's strange when you think about it, isn't it?"

"Yes, it is."

"Oh, there's another fossil."

"Oh, this is a fossil of a leaf. It must have been washed up and sunk to the bottom of the sea and became a ...... fossil."

Saki told us that we can estimate the vegetation of the time from these fossils.

"That's very informative!"

Apparently, Rubina had an aptitude not only for making things, but also for these fields: .......

Merce and Goose continue to canvass the village as they did yesterday.

"I see. Yesterday you talked to old man Yoritoshi."

On this day, he is talking to Aban Sada, another village elder.

"I heard that my ancestors came from Mitsho," he said.

"Oh, that's why your family name is Sada.

"Oh, you know about that?"

Yes. I'm from Huso, next to Mitsuho.

I see. You wanted to hear an old story at ......, right?

Yes.

Then, can I tell you a fairy tale I heard when I was a little girl?"

I'd love to hear from you.

"Then ......"

And thus, Mertze and Guth were working.

* * * * * * * * * * *

Elsa is also basically working in the village.

She had already visited more than half of the houses yesterday, so today was much easier.

"We were lucky that no one was seriously ill."

Not a single person needed a surgical operation.

Thanks to this, we were able to heal all the villagers with healing magic alone.

"Thank you, Erza-sama!

"Thank you very much, you have helped me."

"No, this is what we do."

In terms of receiving thanks from the villagers, Erza is by far the most appreciated member of Jin's group.

No, no, no, no, no, no, no, no, no, no, no, no, no.

"No, no, Jin-san and his group are wonderful people!

Dinner that night was even more sumptuous than the day before.

And it tasted even better.

"Mr. Jin, your magical tool that makes water taste so good is wonderful!

Nona, the wife of the village head, said happily.

"Even when we cook food, there is little lye in the water and the taste is not muddy.

"The hard water has turned into soft water.

"I see. The tea tastes very good too.

Some experiments have shown that when hard water is used to brew tea, the astringency is reduced and the taste is lighter, while soft water allows the full flavor of the tea to be felt.

In general, it seems that the < of ingredients such as dashi (Japanese soup stock) can be tasted better with soft water.

"Nona, Jin-san has ordered us to distribute one of the same magical tools as ours to each of the houses."

"Well!"

"I'll bring it to you as soon as it's finished."

Jin is supposed to be a with a workshop.

It was a peaceful dinner time.

* * * *

After dinner, Jin and his group retired to the guest room and held a brief debriefing to show the results of the day's work.

"......Elsa is the best. The villagers didn't show any serious symptoms, did they?"

"Yes. Yesterday, a total of five people had small stones in their UTI's and I removed them."

Was that all it took?

"Nope. I think that eating yunos and taking citric acid has helped."

Citric acid together with calcium improves the absorption of calcium in the small intestine.

Elsa said that eating yunos (yuzu), a local delicacy, may have some positive effects.

(In fact, even in modern Japan, the theory of calcium intake is still ambiguous.)

"Tomorrow, hopefully, the person we are looking for will come to this village," she said.

"Kuhu, I'm looking forward to it."

"I wonder what kind of people they will be."

"Well, let's not get our hopes up too high."

It's not a guarantee that they will come," said Jin.

That night we broke up and everyone went to their respective bedrooms to rest.
