Please come back again."

The next day, Jin and Erza left Randall's mansion with their hair in their backs.

"Well, we're going to get busy."

"Hmm..."

"Oh, but Erza, don't be too hard on yourself.　It's an important time."

We are planning to have a debriefing party at Horai Island in the evening.

The Jin family will be there.

"......?"

Erza nodded a little disappointed.

* * * *

Jin returned to Horai Island and told Erza to rest and instructed her to mobilize the five colored golem maids to prepare for the party.

"Brother Jin, let me at least give you instructions.

He couldn't stand the thought of doing nothing. Jin thinks about it for a moment and gives his conditional OK.

"Well, ...... that's fine. Edgar, make sure you support me."

"Yes, sir, I will."

And Luna and Soleil, you guys go with him.

Yes, father.

I'll take care of it, Father.

Relieved, Jin went to the command center to hear the report from the old man.

"Now, please give me a detailed report."

The large error is only due to the distance.

<> of <700672> has produced.

"Yes, ....... Should I go and ask them right away?"

<<>.

So Jin, accompanied by Reiko as usual, moved to the bottom of 700672 by the warp gate.

Of course, the old man asked Erza to tell him that they were going out.

* * * * * * * * * * * * *

"Welcome, Jin-dono!"

It seems that No. 700672 has been waiting for Jin's visit.

"You want to know the observation results of the spatial monitor, don't you?"

"Yes."

Then 700672 immediately began to explain.

"This oscillation lasted seven ten-thousandths of a second. It's getting a little long, isn't it?"

"Yes, it is. ...... is it getting longer and longer?"

The question was met with a disappointed look on No. 700672's face.

"It's only been four times, so it's hard to derive any regularity from it, and I guess it's not very probable."

"But that's not the main problem."

"What?"

Jin stiffened at the more serious tone of 700672.

"First of all, the most important problem that we need to focus on is that the material there has disappeared.

"What?

This is new to me. Jin thought that it was only because the 700672 sent a into space that they were able to find out about this.

"By coincidence, one of the spatial monitors we sent disappeared in an instant.

"Disappeared?"

Jin asked, as if to make sure.

"Yes, annihilation. Not destruction. Not just the body. Not a single atom remains, that's why I called it <>."

"Annihilation ......"

We have a new threat.

"The <> was in rough formation, so we have a rough idea of its range. According to this, the radius is somewhere between 100 and 1,000 kilometers.

The large margin of error is unavoidable, 700672 added.

"Is it safe to say it's a large area?"

"Yes, from the point of view of the size of the universe, it is very limited.

The more important question is the effect.

It's not a gravitational destruction, is it?

Jin reconfirms.

"Yes. Such a thing may happen depending on the scale of spatial oscillation, but the phenomenon observed this time is ."

"Are you saying that it is not a mere fluctuation of gravity?"

"It would seem so."

But we don't have enough information on this yet. 700672 will send out more , he said.

"So far, the position of the outbreak has been almost constant.

He said that he would send out many of them around the area of space.

"So, what about you?"

Jin guessed that by "how," he was referring to the .

Thanks to you, the prototype has been completed and is working well. We are considering further improvement in efficiency and larger size.

After saying this, Jin explained the detailed specifications.

"That's great," he says.

"That's a big deal, but in a worst case scenario, it would be dangerous if we don't have enough warding to cover the Ars."

That's possible.

"After all, ......"

Even though the planet Arus is smaller than the Earth, it has a diameter of about 2,400 kilometers.

If it were to cover the entire planet, it would have to be 3000 kilometers in diameter. At the same time, Jin thinks it would be necessary to stretch the moon (UNY) as well.

And he adds.

"If we are not careful, there is a possibility that Ars and the moon (UNY) will go out of orbit. ......"

"Hmm. That would cut off gravity."

Ars's orbit is not a perfect circle. The slight error will be absorbed by the astronomical distance, but it is still a concern.

"I'd like to make this as quick as possible."

"I'm sure."

Then, instead of a spherical boundary covering the entire area, it would be a hemispherical or disc-shaped boundary facing in the direction of the spatial oscillation," he said.

"But that would be difficult without knowing the point of occurrence in advance."

Jin's concern was conveyed to No. 700672.

"Yes, that's right. I will do what I can.

Regarding the collection of information, 700672 said he would do his best.

"Please do."

Jin feels that he has no choice but to leave it to him.

"I will do my best to develop a spatial barrier.

"Yes. Can I assume that technically there are no more problems?

"Well, there is still the problem of energy supply if we continue to increase the size of the machine, but I think we can manage that as well.

"Hmm, I see.

"Worst case scenario, we can transfer it from the etheric cloud."

< is a highly concentrated etheric region near the Lagrangian point of the planet Hale.

From there, we will be able to obtain an almost inexhaustible supply of energy.

I will cooperate with you whenever I can.

Yes, I will be happy to do so.

After such a meeting, Jin returned to Horai Island.
