If Norway is at night, Horai Island is in the daytime.
< were sympathetic to the poor diet of the Principality of Norway.
"You're getting creative with the wildflowers you eat. ...... I could show you some more wildflowers you could eat."
Goose was about to go off on a tangent,
"Kuhu, that's good too, but right now we're talking about helping with magic tools."
Saki nailed him.
"After all, as Bina mentioned earlier, a magical tool that turns seawater into fresh water, is that it?"
"Yes, that's right."
Reinhardt nodded at Jin's words.
After all, the two of them had once made a distillation device in the Kingdom of Elias at the request of the Marquis of Florenziano.
"It's easy to control, as long as it's always in operation."
The problem is the method.
The method of heating seawater for distillation is too inefficient for a magic circle, even if you can use <>.
"Warding or ......"
The idea is similar to << semi-permeable membrane>.
In short, we put up a boundary like bisecting a container filled with seawater.
The boundary allows water molecules to pass through in both directions, while other molecules pass only one way.
This means that, over time, one side of the container becomes closer to fresh water and the other side has a higher concentration of salt and other minerals.
"If it's not drinking water but irrigation water, it doesn't have to be perfectly fresh water, does it?"
Hannah said.
"It depends on the degree, but it might be more helpful for growth if there are some minerals in it.
"That may be true."
Jin agreed.
"However, it is better to remove the elements that accumulate ...... such as arsenic, mercury, and cadmium."
This was the opinion of Jin, who knew about pollution-related diseases.
"Hey, then, why don't we make a lot of magic tools to certain elements from seawater and install them in the waterways?"
Bina voiced a new idea.
That was how Adriana Barbora Zetsi, the first Magecraft Meister, had succeeded in obtaining metallic materials from seawater in the early days of her youthful adventures.
"Hmmm, there are so many elements I want to extract. ......"
After a few exchanges of "No, Jin first" and so on, Jin finally decided to give an explanation.
"I mean, I was thinking earlier, why don't we let the water flow over the boundary that says water is bidirectional and everything else is unidirectional?"
When Jin said this, Reinhardt immediately understood his intention.
"Oh, maybe pure water will drip down."
"That's what I meant."
Bina seemed to feel the same way,
"Jin told me that. I was thinking of pouring the water into a container made of wards, but then the concentration in the container would gradually become thicker and thicker.
Jin's idea was better than his own.
"So it's like this. ...... pumps seawater and pours it into a flume. Fresh water drips from the boundary. Then the salty seawater is poured into the sea. This process is repeated over and over again."
Reinhard summarized the sequence of events.
"That's how it works. This way, the operation is constant, and we only need two magic tools, one to and the other to ."
"Yes, Jin is right. ...... Well, is it too much to ask to develop this?"
Reinhard said regretfully.
"I guess we'll just have to say that this is a donation from ."
"I guess so. ......"
The other members of the did not seem to have any objection to such a decision.

In the Principality of Norway.
In the guest room of the guest house, Gaju Tuga, Fiona Fierce, Manon, and the others were summarizing the results of the meeting.
Of course, they made sure that there was no wiretap, and they put up a soundproofing.
"It was quite a productive meeting."
Gaju Tuguah let out a sigh that sounded like a deep breath.
"Do you think what they said is true?"
"I think it's true."
Fionn Fias said he believed them.
"Yes, I also believe that they are not lying.
Manon said there was no problem, so Gaju Tugga nodded his head in satisfaction.
"Yes. Then, tomorrow morning, after a short meeting, we will return to the garrison.
Gaju Tugga said, "I want to take this opportunity to hear all I can.
"Yes,...... I would like to know the strength of the Duchy of Norway, but I guess that's not possible."
Fionn Fiasse said regretfully.
"If we know the strength of the Duchy of Norja, we can estimate the strength of the Duchy of Jagus from there.
"I can understand your feelings, but that would be a top national secret."
Gaju Tugga said with a wry smile.
"...... Still, we might be able to get a glimpse of the war potential, don't you think?"
Manon said.
"Manon, what do you mean?"
"Tomorrow, I will tell them that I am an automata, and they want to have a mock battle with a battle golem. In the process, you can estimate the strength of the golem in this country.
"I see. ...... but that would be very dangerous, wouldn't it?"
"Yes, it is! Manon could be destroyed!"
But Manon laughs and says.
But Manon laughs and says, "No, I can fix it even if it breaks. I think it is the role of automata to be useful in such situations.
"Manon ......"
"Besides, I don't intend to be broken so easily, do you? After all, it was Jin-sama who created me. He is the Magecraft Meister of this generation.
