Dinner was not at , but at the institute's cafeteria.

This time, Elsa's cooking was the main course.

"Ah, it's so relaxing, isn't it?

Jin and Elsa, plus Meane, Reiko, and Edgar.

This is the latest family lineup.

"Well, I'd like to do a quick review.

This is the reason why we had dinner in the laboratory cafeteria.

The old man activated the magic screen on the wall.

"No, let's start with the equipment and the way of doing things, rather than the island."

.

Jin began by explaining what he felt.

"First of all, I thought again that what we need for a long boat trip is ."

"I understand. ......I don't think that's the right way to put it, though."

Elsa agreed with a wry smile.

"You know, Hannah said she wanted to go swimming, right?"

"That's true. It's hard to be surrounded by water and not be able to swim, isn't it?

The old man concludes.

"Yes, it will be. ...... Can't we divert the water we use for ballast?"

<

"Yes, I think that would be fine.

It would make a big difference.

<

"I guess so."

We are on our way to fulfilling our desire to swim in the boat. Now, let's move on.

"I was thinking that we could form a golem orchestra to relieve the boredom.

"Yes,...... I'd like to make an orchestra ...... with little craftsmen (smith) or mini craftsmen (smith), but I don't know much about orchestras, but I'd like to make such an orchestra and have it play.

"Brother Jin, the Shoro Kingdom also has a military band, is that what you mean?"

Erza asked, tilting her head.

"Yes. It has nothing to do with the military, and it doesn't play only marches, though."

Jin's knowledge of music is limited. He wished for a moment that he had a friend who had the talent to compose .......

"We should also develop string, wind, and percussion instruments."

He would like to make the orchestra as close as possible to the one he envisions.

"You got it."

After reviewing the items that he had noticed during the trip, including some very small ones, it was time to talk about the <>.

<

"Yes. First of all, plants. Balsa, poison oak, palm trees, spices, I think.

And banana trees.

Oh, yeah. Thank you."

Jin thanked Elsa for her addition.

"Let's collect some saplings and try to cultivate them in Horai Island.

.

These will serve as five-color golem maids, Topaz.

"Gemstones are also plentiful, I have seen peridot, quartz, kunzite, topaz, and some slipstones that are not gemstones."

<<

"I see. We should avoid overexploitation, but it might be a good idea to extract some of them as raw materials.

<

"Yes, that would be a good idea.

Jin agreed with the old man's suggestion.

We may not be able to sell them in the market, but the materials are essential for the island of Horai to support this world behind the scenes.

<

"Oh, I knew it."

The mermaid squads were almost totally outnumbered in the Atlas Island where Jin and the others enjoyed their swim.

"I'm sure we'll be fine, though, since we've got the warding in place."

"Father, we are still worried about you.

At Jin's words, Reiko, who had been silent until then, interrupted.

"So ...... you are. I'm sorry, Reiko.

"No, it's not your father's fault. No, it's not your father's fault, it's just our own.

<, and this is an identity that cannot be compromised in any way.

"Thank you."

The old man took care of the follow-up, so Jin decided to think again about the last remaining riddle.

"Now, the biggest mystery. Why was the compressed tungsten lead ore located in that place?"

The old man has a good point.

"You're right, ......, but you didn't find any other clues, did you?"

A larger and larger RAND team searched , but failed to find any of these mysterious substances.

In the first place, finding them was also a matter of chance.

<.

"I guess that's what I thought."

"...... Jin brother, I said hello to the demon people, but not to Mr. 700672. I don't think so."

Erza points out.

"Well, you know.

I had been to the demon territory before, but I didn't have enough time.

"Let's go there just to say hello."

Jin was curious.

"Well, maybe tomorrow..."

Erza agrees.

Since there is a warp gate at 700672, it will not take long to get there.

Just when Jin thought that this was the end for today, the old man spoke to him.

"Yes, what is it?"

<<

We can't know much about it at such a great distance. 's action was justified.

"Okay. Report back to me as soon as you have the results."

<

This time, the day's work is done.

After the preparations, Jin and Erza go to bed.

"Good night, Mother."

"Good night, mother-in-law."

After saying good night to Meane, Jin and Elsa went back to the house. Meine went to her room at the institute so as not to disturb the newlyweds.
