The next day, on the 11th, Jin immediately started to build a super-sized blow floater.

"Well, Elsa is right, it's easy to bring in the materials."

It was very easy to use the direct passage from the underground warehouse.

"I like the idea of a large dock."

Until now, they had to use engineering magic to build a trestle or have <> support it. It was easier than ever before to be able to build a dock while supporting it with a special stand.

"Like this, like this, like this ....... ...... Reiko, get the materials over there."

"Yes, Father."

Smith, I need you to adjust the other side.

Yes, sir.

The work is so much smoother than ever before that Jin is really getting into the swing of things.

"That's amazing.

"I'll never get tired of looking at it."

"......, how about inviting Zion and the others to join us?"

"Oh, that's a good idea."

Marcia, Bina, Erza and others who were watching the show came up with such an idea.

It was immediately implemented.

"I'm here, but ...... what is this place?"

"Jin-san, you're doing something crazy again. ......

What is this place?

Theon, Rhodos and Ludmilla came and were surprised.

"Ah,...... yes, of course."

Bina shrugged her shoulders as she greeted them.

"This is actually ...... a good idea."

Erza explained to Zion and the other three.

"What?

"A blow floater that can carry 10 tons?

"I can't imagine. ......"

Each of the three expressed his or her own opinion.

"It seems that in the world where my brother Jin lived, there were aircraft that could carry that much."

"By the power of the wind?　That's amazing!"

"Nope. That's why Brother Jin says we can do it here too.

"Of course, he's Jin, isn't he?"

"Jin-sama, that's great. ......"

While such conversations are going on at the side, Jin is assembling more and more.

It is truly a spectacle and wonder to watch a huge ingot transform into a huge dish with a diameter of 15 meters in a few seconds.

This is done one after another.

Four circular wings, each 15 meters in diameter, are placed at the apex of a square.

All structural materials are made of 64 light silver. It is a light and sturdy material.

"Now the basic structure is OK. Next is the blow engine.

Jin builds 20 powerful blow engines.

Four blow engines are used for each circular wing. The remaining four engines are for emergency use.

"We need to build one for propulsion."

Eight < of the same type are used, including for directional change.

Four for propulsion and four for directional change.

"The control is basically a golem brain."

Jin thought that since it was such a huge machine, it would be necessary to have a pilot on board to help control it.

Rather than having a pilot on board, he wanted to direct it where to go and let it take care of the rest.

"Basically, it will never carry a human being," he said.

<, or vehicles like the .

"Since we have a little more power, we should try a cargo type instead of a suspended type."

The suspended type would not be able to maneuver too rapidly, and it would be dangerous if the mooring wires were to break.

It also has the advantage of being able to carry supplies other than the golem.

Therefore, we made a light and strong cargo room with 64 light silver.

This allows this <> to be used for purposes other than <> transport.

"Now all we need is a color, but let's not go too fancy."

Light silver can be colored in various ways by adjusting the thickness of the oxide film on its surface.

Jin thinks about making it dark green, and rejects the idea, thinking that it looks like a military aircraft.

"Hmmm, what should I do?

Jin was too tired to think about it and decided to ask Hannah, who was just nearby.

"Hannah, what color would look good on this plane?

Hannah thought for a moment,

"Well, how about white?

She replies.

"White or ......."

There is no such thing as metallic white. White means that it reflects all the colors of the visible spectrum, which in the case of metals is silver.

Of course, Hanna could not fail to understand this,

"Why don't you paint it?

She said, "Paint it.

"Paint?"

"Yes. And then accent it with red and blue."

Accent it with ...... lines?

Yes.

Indeed, Jin has mostly used light silver for the exterior and has not painted much.

"I don't remember any paints. ......"

Then came Saki.

"Kuhu, I have some."

Saki said she had developed a special paint using .

"When did you ......"

"Well, we had the idea about 370 years ago. It was only recently perfected."

<

"Kuhuh, that's what I was wondering. In the first place, it is not yet in the form of threads in the body of a ground spider, right?　We studied how it could be stabilized in the form of threads.

"Oh, I see."

In the body of a ground spider, it is in liquid form, and when it comes out of the mouth, it becomes a stable thread.

Saki has been studying the factors that stabilize them.

"It's magic, after all.

In the first place, the is a demon that lives by ingesting .

Their bodies are made of magical atoms, and the threads they secrete are also made of magical atoms.

Saki said that the threads spit out from its mouth react with the free magic element (ether) in space and stabilize .......

Therefore, it seems that the threads produced by underground spiders (grand spiders) in places like Horai Island, which should be called a power spot of <>, have better characteristics than those produced in other places.

"Then, why don't you ask them to emit <> into the space where there is no <>?"

"Oh, you'll get a source of non-stiffening threads."

"That's what I meant. It wasn't easy, but I managed to get a hold of a ground spider and extracted the source of the spider silk.

Saki said that he named the source of the spider silk as .　Grand　Spider　GST stands for Grand Spider Thread.

"If you don't constantly irradiate <>, it turns into <>."

Incidentally, the reaction between free magic element (ether) and <> is irreversible, hence <> is stable.

Anyway, <> mixed with magic dye before it becomes thread becomes paint.

"If you apply it in the space where <> is activated and expose it to thick <>, it reacts and hardens."

The reason why it is an <> and not an <> is that the golem cannot move within the range of the <>'s effect.

"With <>, the action of stopping the hardening is incomplete, though, and it only takes about 10 hours to work."

< that removes and an that keeps it under control," Saki said.

"No, it's good enough."

Jin decided to try this new paint.
