For two full days, six reconnaissance ships checked the asteroid field.

From the largest to the smallest.

The number of asteroids checked was about 2000.

But still, we could not check even half of the asteroids.

< here, and the remaining five ships go back 60 degrees in orbit. That is also probably the stability point.

The old man gave these instructions, and the five ships of the scouting party set off ahead.

As a side note, the term in this case refers to the direction of orbit. If we look at the Ars North Pole from the top, the direction of the orbit is counterclockwise. In other words, means clockwise movement.

As a side note, in terms of Lagrangian points, the asteroid group was found at a point called L5 from Ars, and the five vessels are aiming at a point called L4 from Hale. The five vessels are aiming at a point called L4 from the viewpoint of Hale.

The five vessels are aiming at a point called L4 from Hale.

"Now, all that remains is ......."

After receiving the report at Horai Island, Jin started the meeting with the old man.

"Now that we have given the airships to the countries, it is possible to go to and from the Kunlun Island, isn't it?

? >>

The old man understood what Jin meant.

"That's good news."

"A phantom ward. It is an important ward for the future concealment of Horai Island.

.

The old man began to explain.

"Yes.

<

Since it includes not only visible light but also ultraviolet and infrared rays, it is impossible to detect with optical instruments. However, it has a disadvantage that no light can penetrate into the inside of the field, resulting in total darkness.

>

The old man further explains to Jin.

>.

"Yes."

This is a countermeasure against the possibility that objects such as boats or demons may come by accident.

<<.

"I see."

>.

<<

<

"But we need to keep monitoring it 24 hours a day."

Jin immediately replies to the old man's request.

"Yes, sir."

As he was told by No. 700672 the other day, it is important to hide Jin's true ability.

.

Jin immediately started to make a special magic brain for warding.

He was not at ease unless he was working on something.

The brain was completed in half a day.

"You will be treated as your servant, old man."

>

"How about the name ......<>?"

I thought about Mirage, but decided against it because it didn't sound good.

<<<< Kagero>>? It means "elusive.

Thus, the auxiliary magic brain that controls the Horaijima ward, <>, was born.

"By the way, Brother Jin."

When Jin reported this to Erza, a question came back.

"I thought it would be completely dark inside the <> ward, but why isn't it so?"

"Oh, I guess Elsa didn't hear me. That's the part I've been struggling with the most. It's not in the first place."

"What?"

At first, I had thought of <>, >, and > as countermeasures, but I didn't like any of them because they all had their pros and cons.

So Jin was working on developing a <> like the ones in the old Leonard's Kingdom as an alternative to <> warding.

"The point is, you can see things because the reflected light enters your eyes, right?"

"Yes."

Elsa nodded.

"So I thought. I'm going to process that light."

"Oh, I see."

It would be more like using image processing software to remove electric wires and other obstructions in a photo.

Such a is the in this case.

< is being played with and replaced by the light reflected by the background.

The incoming light is left as it is, but the reflected light and the outgoing light are modified.

So the incoming light is not blocked at all.

"I see."

Elsa smiled.

"By the way?"

Jin asked Elsa.

"You've been out of the house a lot lately, what's going on?"

But Erza laughed and shook her head.

"No, nothing. I went to visit your mother the other day to see how she was doing."

Elsa calls her <, referring to her foster mother, Marlene. Her own mother, Meine, calls her .

"How are you?"

"Yes. Father is feeling much better, I'm relieved to hear that.

"That's good to hear. But you could have invited me if you wanted to go back to your parents' house.

At Jin's words, Erza said,

"But now is a difficult time for my brother Jin.

Jin replied with a smile.

Jin was happy to hear Elsa's thoughtfulness,

"Thank you.

He sat back down next to her and gently hugged her shoulder.

He sat back down next to her and hugged her shoulder gently.

"Well, there are still some things that need to be done.

After taking a break, Jin went back to the workshop and started to prepare with the help of Reiko.

"Father, what are you going to do?

Reiko asks, to which Jin replies with a smile.

"We are going to improve the performance of the air force.
