Jin and Elsa took a rest at , and the next day, September 16, Jin, Elsa, Reiko, and Edgar visited under 7006 They visited the bottom of No. 700672.

"Oh, welcome!"

No. 700672 greeted Jin and the others with its usual smile. On either side of him stood and .

"Today, I've come to report on the marriage of Erza and me."

Jin hugged Elsa's shoulder and told her.

"Oh, that's great news. Let me congratulate you.

"Thank you very much."

Jin and Erza bowed their heads.

"Well, that's not all, is it?"

After the greetings were over and the usual souvenir of Persica juice was handed over, No. 700672 began.

"You must have something to ask me, don't you?"

"Yes, as a matter of fact, I do."

Jin told the story of the supposedly molecularly compressed azurite ore he had discovered on his honeymoon on the island of Archeone.

"Fumu ......."

Neither Jin nor Erza could open their mouths as No. 700672 seemed to be thinking seriously. Neige and Rouge also looked at him in silence.

After five or ten minutes of deep thought, No. 70067 No. 2 looked up and opened his mouth.

"It may have been caused by the process of planetary remodeling.

"Planetary modification?"

Jin asked back at the unexpected words.

"Yes. I don't know the details myself, but this Arus is the planet where the Masters moved to in the first place.

The story of No. 700672 can be summarized as follows.

When the Masters decided to move to , there were several problems.

One of them was that had a little less gravity for < to move in.

Therefore, <> modified it to have the same gravity as their home planet <>.

The modification was carried out slowly over a period of 100 years, while watching the adaptation of the current inhabitants.

The remodeling of the planet was carried out by <> and <>. The remodeling was carried out by <> and <>.

Migration to , which had been remodeled, also took place in 100-year increments.

The information on the followers before the number 500000 is not available for 700 No. 672 does not have the information of the followers before 500000. Therefore, we do not know the details of the remodeling.

This is what I mean.

"That's why ......"

"That's just my guess, based on what little information I have."

Jin sensed from behind the words of No. 700672 that there was apparently a gap or disparity even among the followers.

"So, to compensate for the lack of gravity, I guessed that heavy elements were injected into the nucleus. I suspect that what looks like compacted azurite may be the product of such an experiment."

This is just a guess, says 700672, but it makes a lot of sense to Jin.

However, it was an explanation that made a lot of sense to Jin.

"After all, the fact that this star has a large gravity for a small planet is the result of such modifications, isn't it?"

"Yes. There is no doubt that modifications were made. But I don't know the details of the modifications, so I can only speculate.

Still, it was an interesting story about the origin of stars, Jin thinks.

"Do you know how your were molecularly compressed?"

Jin asks the few remaining questions.

"Only in my imagination, yes."

With that, No. 700672 began to explain .

"You determine the target location and perform a multi-layer multi-layer compressive transfer."

"Multilayer Multilayer Compression Transfer?"

Jin asked back at the unfamiliar word.

"Multilayer Multilayer Compression Transfer is a magical technique developed by the Masters to generate high-density matter.

Jin listened attentively.

"I am not privy to the details, but it is difficult to actually do so, although the density can be increased by piling matter on top of matter.

Apparently, there is a gap in information as well.

"It seems that they do this by creating a boundary that makes it possible and sending matter inside of it."

I don't know anything more than that," said the apologetic 700672.

"No, that was helpful."

Jin is using a compression boundary to forcefully compress the molecules, while the masters seem to be doing it a little smarter.

However, Jin's method leaves a gap after compression, and the mass does not change in the first place.

If you want to increase the gravity of a planet, you have to bring in material from somewhere and add it, which is not to say that Jin's method is impossible, but it is too much work.

"Perhaps they increased the gravity by a factor of about twice the original amount?"

"I see. ......"

Although the planet was originally as heavy as adamantite, the gravity was still about 0.5G, so they must have modified it to double the original gravity.

"I do not know how this would have affected other creatures. When I and my came here, the gravity was already the same as it is now.

Planetary modification may have been done as a test case tens of thousands of years before the migration," 700672 said in a further bombshell. He dropped another bombshell.

"I do not know the whole truth. In fact, compared to the 100,000 number, I know nothing at all.

"Haha ......"

Jin wondered if this world had been created by such followers of the 100000th and their masters.

(It's not worth thinking about, though.)

(It's not a good idea to think about it, though.) This might be the origin of myths and legends, reminded Jin of the science fiction and anime of his days in modern Japan.

"By the way, what about <>?"

The 700672 also seemed to be concerned about this matter.

"Yes, we sent out an observation rocket to investigate the details.

"Oh, that's good. After all, the planet has an extraordinarily long period of time, and it goes away and comes back far away, so there's no guarantee that it's the same as the last time.

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

The sun Celan is one of the foci of the long elliptical orbit, but we do not know what is near the other foci.

I am taking some steps to deal with it, though."

What are they?

A small gravity stabilizer and a large gas field.

<

And if the atmosphere is lost to a , it would be a big deal.

This is what 700672 explained.

You are right. I have to do something.

"Then, Jin-dono, you may accumulate your free magical element (ether). After all, it is energy that we need when the time comes.

"...... understand."

I understand what you are saying, 700672.

If we were to set up a planetary scale warding, how many ordinary <> would be needed.

Reiko's Magi Reactor would have to be multiplied by millions, Jin could not imagine.

Still, the secure energy supply would be useful in many ways.

"I'll work on it right away."

"Oh, I'm sure you can do it, Jin-dono. I'm counting on you."

We can't risk this world, 700672 said.

"I'm sorry to be so formal with you, ma'am. Yes, accept my congratulations."

700672 went to the back of the room and came back with something that looked like a small box.

"This is for the both of you. It is called a camera.

"A camera?

That's right. You look through it, point it at what you want to project, press this button, and after a while, a sheet will come out with a picture that looks exactly like the projected image.

It was, after all, the that Jin knew.

"The principle is ...... no, I'll save that for Jin-dono's enjoyment.

"Thank you very much."

Jin gladly accepted it.

He had often wished he had a camera, but he could not make photographic paper.

Jin received the camera from No. 700672, confident that if he studied it, he would be able to make it.
