Raindrops fell from the leaden sky.

The wind was creating white, foaming waves, and the surface of the sea was undulating, tossing the floats about.

Observations from <<<< watchers suggest that this rain cloud will pass in about half a day.

<.

"Well, there are days like this.

"Yesterday's sunset was a bit toxic, maybe because there were clouds in the west.

"We came all this way, but we can't see anything because of the bad weather. Disappointing.

It was Bina who was grumbling like that.

"Oh well. It's supposed to clear up in the afternoon.

Hitoshi soothes her.

"Yeah, I guess so."

Bina leans back in her chair. Her body finally seems to relax.

Then Licia comes in.

"Hello everyone, it's been a while. Mr. Jin, thank you for inviting us today.

Licia bowed deeply at the entrance of the cafeteria.

"Hi, Licia."

Jin greeted her lightly and Licia walked up to him,

Jin-san and Erza-san, thank you for inviting us.

She bowed deeply.

"Well, enough with the formal greetings, please have a seat.

"Yes, thank you very much.

"It's raining here, isn't it?

It's raining, but it was fine out there.

Reinhard and Bertsche also arrived.

This meant that all the members except for Milowina were now present.

The first thing to do was to meet in the cafeteria.

"Well, according to the images from the <>, the rain clouds that are causing this rain are supposed to break up around noon. So we just have to be patient a little longer.

Jin explains to Mr. and Mrs. Reinhardt and Licia who have just arrived.

"So, I think we should just pass the time until noon, especially those who are usually busy. Especially those who are usually busy.

With these words, he looked at Mr. and Mrs. Reinhardt, Licia, and Count and Countess Kuzma in turn.

"Oh, yes. I have a little problem that I was wondering if you could help me with. I'd like to ask you all for some advice. ......."

Reinhardt opened his mouth a little hesitantly.

"Is something troubling you?"

Jin asked and Reinhardt shook his head.

"No, it's not that I'm in trouble. I'm ...... hmmm... but I'm a little troubled?"

"You, that kind of language won't get through to the Djinns. Please explain in more detail.

Reinhardt seemed to have made up his mind after being rebuked by Bertsche.

"Uh-huh, okay."

He thought for a moment and then spoke again.

"It's hot on this ship, but the season is heading toward autumn.

Reinhardt started off with a preamble.

"It gets quite cold in the village of Kaltz, my home village, in the winter," he said.

"Yes, that's true."

Saki, our neighbor, agreed.

"I'd like to think of a winter plan for the villagers while we're at it. ......"

Jin thought that it must have been difficult for even Reinhardt to ask for advice on how to deal with the cold weather in this hot environment.

"Yes, we are heading into the cold season, aren't we?"

Licia agreed.

I guessed that Licia, Hannah, and Martha were the only members of the group who lived in a region with cold winters, besides Mr. and Mrs. Reinhardt.

The climate in the Blue Lands is mild enough that there is no snow in winter, and Potrock is warmer.

But..,

But the winter cold is hard on them.

Bina, who lived in poverty with her younger siblings, seemed to understand this feeling.

"It's a good idea to protect yourself from the cold in winter. Let's talk about it until noon.

Bina said and looked around at the faces of the assembled members. And no one objected.

Everyone likes this kind of consultation and meeting.

"Onii-chan put white mica on the window, didn't she!"

Hannah was the first to speak up.

She put a plate of highly transparent mica (moschovite) she found in the mountains in the window instead of glass.

This allows sunlight to enter the room and keeps the warm air out.

"Mica or ......"

Reinhardt looks at me with a difficult face. He knows of its existence, but the Shoro Kingdom does not produce much of it.

"But glass is expensive," he says.

Whether it is made by magical engineers or in a factory, there is no doubt that it costs a lot.

"If it's going to cost a lot anyway, why don't we use <>?"

Saki shows a direction.

He suggests that we should put a thinly stretched board or sheet of GSP on the window.

The image is that of transparent vinyl. Although the strength and heat resistance are not as good as those of GSP. Once put up, it would last for more than 100 years.

"Hmmm... ......"

Reinhardt pondered.

If we don't mind the initial cost, the price per year should be quite low, assuming it will last for 100 years. In fact, the window frames might not even last.

"We could import glass from Mitsho for a little while longer..."

Guth says.

Mitsuho has a manufacturing plant for what is commonly referred to as . Eventually, with the exchange of technology, it will be possible for the Shoro Empire and the Lesser Kommunities to produce glass at low cost, but that day has not yet come.

"Reinhard, what about the threads of the subterranean spiders brought by Tenkunhan, though they are not as good as those from Horai Island?"

Once, there was a row involving Goose.

"Well, the unit price is not so good ...... and the technology to make transparent sheets is not so common yet."

"Oh, I see. ....... "Oh, well, it's a difficult thing, isn't it?

"But I think it's meaningful to make products that benefit the general public."

Jin interrupted. He then turned to Bina.

"Hey, Bina..."

"Yes, I think so. Yes, I wish I could be like that.

Jin remembers helping Beena in the past at the Blue Lands, building lighters, water heaters, and refrigerators.

"That was fun, wasn't it?"

"Yeah?　...... I did. It's thanks to you that I met Mr. Lewis.

After reminiscing a bit about the old days, Jin makes a proposal.

"Then, a portable stove would be a good idea, wouldn't it?

"A portable stove?

"Yeah, it means movable.

"Movable...... means it's not stationary or built-in, right?"

"Yes. For example, you can put it in the dining room when you eat and take it to your bedroom when you sleep. ......

"That's a great use for only one!"

"Yes, yes. If you have a wealthy family, you can have several of them.

As Jin exchanged these words with Bina, he remembered his time in the Blue Lands.
