Saki, Goose, Vivian and others arrived.

"Jin, I heard you made a telephoto device.

Goose spoke to him.

"Yes. <

"Oh?　Why is that?"

Saki wonders.

"Actually, it's ......."

Jin explained,

"And, the clairvoyant function ......."

"What do you mean, it's ......"

Both Saki and Vivienne were a little taken back.

"That's why I was talking with my brother Jin about not using it casually."

"Yes, I know. People are skeptical, so it's better not to talk about it with anyone outside the <>."

Goose said to be careful.

"But I think if we use it right, we can find out what's wrong with the body."

Yes, it should replace X-rays, CT scans, MRIs, ultrasounds, etc.

"Oh, medical use. Yeah, that's a good idea."

Saki seemed to agree with me on this point.

"Well, let's leave the medical use to Erza.

There are no accuracy or structural problems since it is for close range use.

Since it is mainly a matter of ease of use, Jin decided to leave it to Erza, who would be the user.

"Yes, sir."

I'll concentrate on developing the long-range version.

Jin and the others are doing well.

What about Saki and the others?

< and .

"Yes, it is just a theory, but I have summarized it, including your speculation.

Guth spoke on behalf of the group.

"<> came to Arus from Hale where the resources were depleted. There is no doubt about that. But from what I have heard, the individualistic <> lived in groups of families, or at most neighborhoods."

"Hm."

That was an interesting hypothesis.

"Of course, when they migrated, many such groups would have gathered together to form <>. < might have gathered together to form a ."

In this case, "territory" does not mean a territory, but rather a group of towns.

It would not have been a <>. The would not like such an ."

Jin listened with admiration, thinking that this was a very perceptive observation.

"And then, someone arrived on the island of Onogoro as an advance party.

Guth concluded by saying that they must have remodeled Arus and changed it into an environment that they could live in comfortably.

"So much for the ."

I'll tell you next."

Vivian spoke up on Goose's behalf.

"And then the advance party landed in the <> as well. < are individualistic, I doubt that the people who landed in the < didn't care about the .

Jin agreed inwardly.

"On the other hand, is still collecting free magical elements (ether) to make its habitat more habitable. ...... and"

Vivian continued, saying that it would be a leap forward from here.

"They are sending free magical elements (ether) and ...... resources to Hale."

"That's your guess, isn't it?"

"Yes. And the rest is our guess."

Vivian nodded.

"We need materials to build a ship to emigrate from Hale, where the resources are depleted. They mined and sent mithril silver to this planet. That is why there is so little mithril silver on this planet.

"I see."

It's a bold theory, no doubt. But it makes sense.

"And the materials we sent out were effective for the who refused to emigrate. And even now, free ether is being sent to Hale.

That's all," said Vivian.

"Well, that's an interesting theory."

"Well, it's an interesting theory," said Vivian, "though I have my doubts. There is so little information available that the later we have to resort to fictions and guesswork.

"I guess so."

Jin can understand that. However, when you give us this much background information, it gives us a guideline for our actions.

"I don't know the reasons or motives, though. For example, why is the free magical element (ether) being sent to Hale? Moreover, if free magic element (ether) is sent, it doesn't have to be from this planet.

I wouldn't think of going to check it out if such a mystery could be solved without us even being there.

"That's true. I'm sure that Jin will reveal that to us in the future.

"If I could, yes."

"And ?"

Finally Guth spoke up.

"You are the administrator of , one of the strongholds that the established here in Arus. However, your allegiance is to only a small portion of the <>."

"What?"

"The fact that he did nothing about the < uproar is proof of that. Perhaps the <> is not here in Ars. I'm sure of it, since he stiffened when I tried to ask him."

"If he is, it's either Hale or ......."

"That's what I'm saying. That doesn't mean he's on Ars' side. Worse, they may not even be neutral.

That means that they would do anything to the detriment of Ars for the sake of their master in Hale.

"Okay. Thank you, guys."

Jin looks at his watch.

"It's late already. Let's have dinner.

It was 6:00 p.m. according to Horaijima time.

"Oh, this is delicious.

The menu for dinner consisted of white rice, miso soup with fried bean curd, chilled tofu, boiled tofu, vegetable and white fish tempura, and fried eggs.

All of them were Jin's favorites and Saki's favorites, too.

"Hmmm, maybe I should learn to cook too.

Saki mutters as she drinks the miso soup.

"Aaru is so talented. ......"

Jin chuckles and Erza offers a word of advice.

"Saki, if you are willing to do it, don't be greedy, learning one by one is a shortcut in the end.

"I see. Hearing it from Erza's mouth, it has a lot of weight to it.

Elsa, who grew up as a young lady and couldn't do anything, is now an accomplished housewife.

"A work of love, huh?"

"......, yeah."

"Ah, Elsa. You've grown in stature, haven't you?

Saki couldn't help but giggle when he nodded at her with a straight face.

"By the way..."

Goose, who had finished eating first, opened his mouth as he sipped his hojicha.

"Hmm?"

Jin, who had also finished eating, looked up.

"What happened to the story about going to the demon territory?

"Yes. Let's go to the demon territory tomorrow with <>. I don't think this will be the end of our research, especially since the free ether transfer is going to take some time.

"I understand."

I've been here many times, so I know what it's like over there, so I'm comfortable with this kind of thing.

"I don't think we need to prepare anything in particular. Well, let's go easy."

"Kuhu, only Jin can say that, right?"

Saki says with a wry smile.

"It's not something we should be talking about now..."

"That's terrible."

Jin, who knew that she did not mean it, laughed merrily.

Jin is more than happy to be able to have such a casual conversation with Saki.
