The next day, Jin presented the bracelets to Bina and Count Kuzma as a token of their family.

Bina's is crimson, and Count Kuzma's is yellowish green.

When the two were told how to use the bracelets, they were puzzled.

"Can we really be allowed to receive such an amazing magical tool?

But Jin smiles and tells them.

"It's a sign of trust. Everyone wears them."

"......"

At this point, Bina says what she has been thinking.

"Hey Jin, what if, what if?　What if we tell the whole world about this place?　Will we be punished?"

"What kind of secret society ...... are you talking about?"

Jin laughed and continued.

"I told you my secret because I trust you two and I trust you. If they were to tell anyone, it would have to be because of some compelling reason.

"Jin ......"

"If that happens, I'll take care of it.

"That's right Beena-san. This Houraishima won't be affected by anything.

Even Reiko tried to reassure Bina with such words. The content of her words is another matter.

Incidentally, the so-called by the old man had already been done when Jin had said he would invite them to the Kunlun Island.

Since the result was acceptable, he had no plans to talk about it unless Jin asked him about it.

Before noon that day, Bina and Count Kuzma returned to Blueland.

Jin and Reiko went with them to install a warp gate in the basement of the Count's house.

Now they can come and go as soon as they need to.

"But you can't use it without the bracelet..."

"I know."

And since we'll be going through the Shinkai, it'll keep out any suspicious people.

"I understand. I will be very careful. I will not let the servants know about this."

Both Bina and Count Kuzma agreed to keep the secret.

"I'll see you later. If you need anything, please use the communication function of the bracelet.

With these words, Jin returned to Horai Island using the warp gate that had just been installed.

"Now then, all that's left is ......."

"Brother Jin."

Erza came to Jin relaxing in his on Horai Island.

"Are you worried about something?"

"No, I'm not so much thinking as worrying."

"About what?"

"About Licia and ...... Milowina-san."

What?

Elsa was surprised to hear two names mentioned at the same time that seemed to have no connection at all.

"No,......I was wondering which should come first, getting Licia to join the family or bringing Mr. Milowina here once."

"......Licia to join the family after all?"

"Yes. If Egelea Kingdom is Beena and her family, Klein Kingdom is hers, I thought.

"...... I understand that. By the way, speaking of Licia, I noticed something, okay?

Jin nodded, wondering what Erza had noticed.

"Well, the other day, Licia-san said that she wanted to make juice and jam a specialty of Toka village."

"Yes, that's right."

Jin remembered that Lambel's juice and jam were delicious.

"Jam is one thing, but not juice. It doesn't keep well.

"Ah..."

Jin realized what was being said.

"I don't have to worry about Persica juice and Citran juice in Horai Island because of the <>."

"I don't think even a ...... refrigerator would be able to do that."

The limit for 100 percent fruit juice is two or three days at the most.

In such a short time, it would barely make it to Charles Town. There is no way we can get it to King's Landing.

"Oh, I forgot about that..."

I think you should tell him.

"......, I guess so."

Then, the first thing we should do is to follow up with Licia. It is up to Licia to decide whether or not to invite her to Horai Island.

The old man advised.

"Oh, I see."

Unlike the independent village of Kaina, Toka Village is undeniably a part of the Klein Kingdom.

It is mandatory to pay taxes on the harvest.

"What?　Isn't tax payment in the fall?

Suddenly, Jin remembers that when he was in Kaina Village, taxes were paid in the fall.

"Oh, I see."

Of course, the total amount should not increase, the old man adds.

"Well, you can go to ...... when you come back."

"Brother Jin, don't forget."

"Ugh, ...... I'll be careful."

Then, the first thing to do is to go to Milowina.

"Have you been well since then?"

, you are well enough to walk around by yourself. He also told me that he was able to restore the gravity to 1G the day before yesterday.

"Oh, that's good news. Well then, let's invite him to Horai Island.

"Brother Jin, what are your countermeasures against the pathogen?"

Erza gives an advice.

"Oh, yes. <.

In short, a space suit with warding. For a long time, he had been thinking of generating a field along the surface of the body.

"That would be a good idea.

Jin then decided to start work on the development of a "body surface ward," which had been in limbo for some time.

"After all, I think I can do something if I can specify a starting point.

Jin did not think nothing of it.

"You mean, a boundary with the surface of the body as the starting point and the distance from there as the minimum?"

"Ah. This can be easily applied to Reiko, for example. The skin is the leather of an ancient dragon.

It's easy because it has outstanding properties against magic.

The problem is the people. ......

"That's right, Elsa."

Jin nodded and crossed his arms thoughtfully.

The human body cannot be clearly delineated by skin and muscle. Epidermis, dermis, and subcutaneous tissue.

The epidermis does not have blood vessels, but the dermis does. This is why the concentration of mana and ether is not constant.

"The concentration of mana in the blood changes, doesn't it? ......"

At the moment, taking such errors into account, it seems possible to construct a ward up to about 10 cm from the skin surface.

"What happens if we go below that?"

"In the worst case of error, parts of the body will be exposed through the warding."

Jin thinks that elbows and knees are likely to be exposed.

For example, if you were exposed in a vacuum, you would be in big trouble.

"...... is difficult."

Elsa also tilted her head.
