"Uh, something like this."

Back in time, on October 10, 3459, Jin was making on Horai Island. 2> on the island of Horai.

"I don't remember the details of what was going on. ...... Well, never mind."

He thought that if he had the compulsion of time, he could make the same thing as long as he did whatever he wanted.

"How about you, you ......?"

"How about you, Mr. Goshujin?"

"Duh."

"Ohhh!"

Erza came to the workshop holding Chloe and Anne holding Mio.

"Well, everything is going well."

In front of Jin, a frame made of 64 shiny, silver-colored light silver was being built.

"After carefully applying < to this, the engine and other magi-machines are installed, the interior is done, and finally the exterior panel is affixed to finish.

"It's very different from the first."

"Yes, it is. This one is better in every way."

When it's finished, I'll build a museum on Horai Island and put it there," Jin said.

"Oh, that sounds good."

Jin thinks that the museum should be built in the basement of Horai Island.

The basement would make more sense as a warehouse.

"Ah, but the ceiling should be openable, otherwise it would be difficult to bring it in..."

The old man advised me.

"Oh, I see. That would be fine."

Jin's hand does not stop as he continues to reinforce the framework.

Jin does not use a so-called structure.

Although it would reduce the weight, there is a disadvantage that if one part breaks, the strength of the whole structure would be compromised.

(And it wasn't monocoque either.)

And the fact that , which Jin rode in the future, was not a monocoque structure is the deciding factor.

When will it be ready?

"By the end of the day. Then we can all take a scenic flight together.

You mean, everyone, including Chloe and Mio?

Yes, that's right. The cabin maintains a constant atmospheric pressure and the main engine is a force field generator, so there won't be any G-forces.

"Hmm, that's good."

Erza thought it was outrageous to allow Yu and Mio, who were still infants, to experience accelerated G-force, but she was relieved to hear that Jin had thought it through.

For the next half hour or so, Elsa and Anne held Chloe and Mio in their arms and watched Jin's work, until the twins began to squirm,

"You take it easy," she said.

He then pulled the twins toward the house.

Jin continued to work on the assembly,

"Okay, it's done."

Finally, he had completed .

"Father, how about a test flight?

Reiko asked,

"Well, ...... it's already dark outside, let's do it tomorrow.

He stretched his legs and returned to the house.

* * * * * *

The next day.

"Father, it was a great success!

Reiko, who had been waiting for dawn to make a test flight, came back.

"We've circled the moon!"

"Yes!"

Soon, in the past?　Jin of the past will go to the moon with this .

Jin was satisfied with the result.

However, he had one question.

"The I rode that time was as good as new. ......"

There are two immediate reasons for this.

One is that it was a replica. In other words, Jin may have built two and entrusted one of them to 70067 and entrusted one of them to 70067-2.

The other possibility is that Jin left it to No. 700672, and he continued to use as before. 1> as before.

"Either one makes sense if it's ......."

Jin chose to build another one with a new design rather than build two identical ones.

"First of all, I have to go and ask the 700672 for this."

After breakfast, Jin refused Erza's request and headed north with Reiko through the warp gate.

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

"Oh, Jin-dono, it's been a while.

It's been a while.

What's the matter today?

Jin handed Neige the Persica juice he had brought as a souvenir and turned to No. 700672.

"Yes, actually. ......"

Jin explains the situation.

"Hmm. He said, "...... that about 400 years from now, Jin-dono will appear and he will need this <> thing. So you want me to take care of it for you."

Yes, that's right. How about ......?"

700672 nodded.

I don't mind. I have a body with no life expectancy. I'll take it.

"Thank you!

I'm curious to see what you have created, Jin-dono.

After he had the location specified, he sent the body through the transporter.

"So this is the . Interesting. It is indeed the work of Jin-dono."

...... I'm sorry, but I'll be counting on you for the next 400 years.

Yes, I accept.

I'll take care of it.

"Well, I'll make one for myself!"

Jin returned to Horai Island and got back into the swing of things.

"What, not yet?"

Erza looked at him doubtfully.

"That was for me in the future. Now we need to make one for the family.

"Family ......"

"Yes. Chloe and Mio can ride together, and it's safer. ......Well, let's call it <>, which means <>."

"Taube......"

"You can look forward to it!"

Jin here doesn't know that 400 years from now, Jin will also be building a <> named <>. .......
