The sixth spatial oscillation occurred late at night on the 28th (Penglai Island time).

It occurred near the relay station that Hale had built in the past. It was in the vicinity of the L4 Lagrangian point.

Jin was awakened in the middle of the night, and instantly woke up and listened to the report.

<

"Is <> safe?"

<

We must avoid damaging <> now.

In a few hours, <> will send a large amount of Aethenol, which will be used to drive the wards protecting Ars and the moon.

"I'm off to 700672. ...... Reiko, let's go."

"Yes, father."

Jin prepared himself and went with Reiko to visit No. 700672.

"Oh, I knew you'd come."

700672 welcomed Jin and Reiko.

"Once again, spatial oscillations have occurred. I fear that if this continues, it will occur in the vicinity of Ars in three or four days."

"That's what I'm worried about too."

Jin then confided that he would finally be able to start mass-producing the generator.

"That's good news. Please hurry. If there is anything I can do, I will cooperate with you anytime.

"No, I would like you to continue your observations.

Probably by the end of today, the 28th, we will have a warding generator that can cover Ars and the moon.

The problem was Aethenol, which would probably be ready by the end of the day.

"Well, we just barely made it in time. You're the real Jin-dono, aren't you?

"No, I've learned a lot from you.

You're very reliable. ...... Jin-dono. I hope you will protect this planet and this world. This place where my former sleeps as his second home.

Jin replied without a pause to the unusually sentimental line spoken by No. 700672.

"Of course. This is my second home, too.

This was also Jin's sincere feeling.

After exchanging a few words, Jin returned to Horai Island.

* * * *

"Well, everything is going well. Let's get ready to go."

At last, the warding generator that will cover Ars and the moon is ready to be built.

However, the control part is already completed since it is common to all of them. What remains is the activation part.

"The first step is to synthesize the magi crystals.

Even if multilayered technology is used, the final stage, the warding generator, will have to be of a certain size.

Furthermore, if energy efficiency is important, it is also necessary to prepare high-quality magi crystals.

"Father, is this enough?"

Reiko came in carrying a mountain of magical crystals. She needed them to make a composite magi crystal with a diameter of 2.2 meters.

All the crystals are of the dark attribute.

They are perfect for me, since they have a high intrinsic free magical element (ether) frequency and a large inventory due to their limited usage.

Thank you, Reiko. ......<<<><>......aze"

First, a cylinder-shaped object with a diameter of 2.2 meters and a thickness of 1 meter was synthesized.

"It's indeed a lot of work to make something this big. ......"

<

"Father, please don't strain yourself."

Reiko looks worried.

"Oh, I'll be fine. Now, let's try again <>"

Jin...who makes five identical ones.

Repeating the same process over and over again, even Jin is beginning to feel tired, as he has been doing it continuously since last night.

"Jin, dinner!"

Elsa arrives at the office to inform Jin of her lunch.

Jin, too, stopped his work. Reiko looked at him with relief.

It was tempura udon for lunch.

"You smell the oil, okay?"

She had heard somewhere that when you have hyperemesis gravidarum, you become sensitive to such smells, and the smells that you used to be fine with become no longer acceptable.

"Hmm, I'm fine. Thank you for your concern."

But Elsa seemed to be fine.

However, she seemed to be right about her craving for sour food, which she had also heard about, and after eating a small bowl of udon, she had eaten five pieces of citron.

"How's your progress?　Are you pushing yourself?"

Elsa asked Jin over a cup of buckwheat tea after lunch.

"Yeah, I'd say things are going pretty well."

Jin was a little vague. I'm tired, but not too tired.

He thinks that it should be a little easier since all he has to do now is to combine the pieces.

"I'd like to help you, but ......"

No, Elsa, you take care of yourself.

Jin told her that was more important.

"......"

Erza nodded her head.

After this exchange, Jin and Elsa began to talk.

After this exchange, Jin resumed his work.

This time, he used two cylindrical magi crystals of 2.2 meters in diameter and 1 meter in thickness to create <><><><><>>. Stransform>><>.

Make another one. The cylindrical shape is for easy writing of multilayer magic circle.

Leave the other one as it is.

"Father, the two big ones are for Ars and the small one is for Moon, right?"

Reiko asked to make sure.

"Yes. Now we have to load them on the spaceship.

Then Elsa came over to check on them.

"Brother Jin, isn't the only spaceship that can carry this?"

The result was a cylinder 2.2 meters in diameter and 2 meters thick. There is no room for it on the , which has a diameter of 10 meters, or any other small spacecraft.

There is no time for modifications, so existing spacecraft must be used.

With the 100-meter-diameter < in position in the etheric cloud, that inevitably leaves only < left.

"I'm thinking about it. You see, there are three ships built by <>, aren't there?"

"Yeah, I think ......<<<<>?"

The three ships are of the same type as the , but are more powerful and armed, so to speak.

And you're going to use them?

"That's what I mean. This will save us the trouble of building one."

Erza agreed.

"Good idea."

"I've already made a request through the old man. It would be easier to install it on the moon instead of here, since the gravity is weaker there.

Jin said that it would be more efficient to do the installation under the gravity of the moon (UNY), since the work would be much worse under the weightless condition.

"I'll go with my doppelganger.

"Nah, I'll be there."

"Yeah, I'll take care of it."

Thus, Jin sends three units of the spatial barrier generators to the moon. Next, he sent a hundred Smiths as workers, and finally his own doppelganger.
