"Yes. Perhaps it shows the location of the base of the ."
"What?"
That's important information, Jin thought,
"However, I don't think they put everything. Perhaps only excerpts or less important bases or bases are included.
"But it would still be helpful."
Both were marked on the , and Jin took the duplicate again and put the original back in its original position, just in case.

<, we visited the .
"Oh, this is the technology of the < ......"
The < is in a good mood, having been able to touch the relics of the tribe that made him.
The interior is not very large, being a triangle 25 meters long and 25 meters wide.
The walked back and forth through the triangular space, and touched the technology of the to his heart's content.
"Well, thank you, Master Jin.
After spending about an hour going back and forth inside the submarine, seemed satisfied for the moment.
At that moment, Marcia, who was standing nearby, rather than Jin ......, asked a question.
"Excuse me. <
That was the question that not only Marcia but almost everyone who saw this submarine had.
"Hmmm. ......Yes, first of all, the premise is wrong."
"Assumption, sir?"
"Assumption, is it?" "Yes. First of all, there was a purpose for this shape, and this shape was made to be pressure-resistant. <
"Yes, yes, ......."
Jin guessed that they had the technology to make this shape, which is disadvantageous in terms of ...... pressure resistance, sufficiently pressure resistant.
In fact, there are many examples on the modern earth where design is given priority even if it is aerodynamically disadvantageous," he said.
"As for the purpose, it was probably used for a mission to hide under the sea floor and wait for something.
Waiting for something?
"Waiting for something. For that, a flat shape like this would be advantageous.
Yes, that's true.
I'm sorry, I don't know what it's for.
No, you've been very helpful.
Now I understand a little more about how the designers approached their work.
It seems that they have a slightly different direction from that of Jin and his colleagues.

In the evening, all the members gather for dinner at the institute's cafeteria.
"No, it was a meaningful time. Thank you, Mr. Jin.
First, the gave his thanks in lieu of a greeting.
After that, the meal was served as usual.
The dinner was a congenial one, with conversation.
"Jin, thank you for inviting me!
"Jin, you've been very informative."
Marcia and Rodrigo thanked Jin.
"Jin-sama, I learned a lot from you. Thank you very much.
Marikka also thanked Jin while chewing.
"But didn't the <> people think much about the unity of design?"
Rhodes asked the <>.
"Yes, they tended to do so. were individualistic, so they all made what they thought was good ......."
Since this was a chance to deepen their understanding of the origin of the idea, Guth and Vivian also asked questions from a different angle.
"So, it was an individual who built these and ?"
"Probably yes. That's how much power the <> had as individuals."
"Yes. ......"
"Not quite the Jin-kun of today, but close to it. ......"
If there were hundreds of such individuals, no wonder it was possible to remodel and move planets, they all thought alike.
"However, there is no doubt that this remodeling of Ars was a major undertaking. That's why they've been monitoring the crust for some time.
"Oh, I must apologize for that."
Jin apologized to the <> and everyone else who had failed to see the actual that he had initially examined, and had already returned it to its original location.
"Well, it was probably a . Well, let's wait for the next time. Besides, we have the data that Mr. Jin has compiled."
I'm sorry.
"But I have no idea what this is. ......"
"I see. ......"
Saki looks disappointed.
"It's similar to GSP, but it seems to be smoother and less friction. It also seems to be harder."
"Hmmm. ...... might be a material from Hale."
"Oh, I see. ...... Oh, so what if it is?"
Here Saki remembered <.
"......It might be this one."
Saki pointed to the creature described in the middle of the book.
It was a giant insect that lived underwater. It was described in Haelic as a .
"<<2 meters long, feeds on humus, spits out threads and builds nests. The threads are tough and can be kept semi-permanently underwater>>......."
"Hmm, I think I've heard of them."
< also seem to know something about the worm.
"I remember that the resin made from its threads is hard and lubricious ......."
"Oh, that must be it."
"...... Hmm, too bad. If those insects were still around today, we could use them to coat our boats."
Marcia looks disappointed.
Neither Earth nor Ars had the same problem of increased drag caused by barnacles and other adherent organisms on the bottom of the ship.
The use of a copper-based alloy would have improved the situation considerably, but now there were concerns about corrosion.
"I wonder if there are any more of them in Hale now?"
"I don't see them. ......"
I wonder if there are any eggs or pupae left?
I haven't looked into that. Do you know ...... the detailed ecology of the species?
The book doesn't go into that much detail.
That's too bad.
However, the research on Hale is still ongoing, and if it is a vigorous insect, there is a possibility that it survives, which means that there are more objectives for future research.
"Is there any possibility that there is a more detailed < somewhere?"
Jin asked the <.
"Well, ...... it's hard to say. would not have done so unless they felt like it."
"I see. ......
"But I can't say for sure that they didn't. It is worth looking for."
"Well, it will continue to be one of the objectives of our undersea exploration."
