When Jin reports on the development of Toka Village,

Reinhard asked, "What is the response of the Klein Kingdom?"

Reinhard asked.

The village head didn't seem to know that in detail. It might be better to ask Zion about it."

"That's true. ...... And Jin is going to make a ?"

"Yes. I'd like it to be a donation or loan from deus ex machina." "Since you're Jin, you might want to ask Zion.

"Since you're Jin, you'll start tomorrow, right?"

"Of course."

When Jin nodded, Reinhardt's face lit up,

"I'll help you!

Jin smiled and agreed.

"And I'll have the fifth column (quinta) check the quartz plugs that were blocking the hot springs.

Jin was not sure how far he could go with this investigation, since it was simple and happened a long time ago, but he thought that it could not be left unattended.

* * * *

Reinhardt was waiting for it?　The next day.

As soon as he finished breakfast,

"Jin!　Let's go!"

Reinhard tapped Jin on the shoulder, who was still drinking tea.

"Bertsche-san, are you sure about that?"

asked Elsa, Reinhardt's beloved wife Berthe.

"Yes, isn't it okay?　Before he died......Oh, that's a funny way to put it. Anyway, 350 years ago I was too busy being a lord or a diplomat or whatever to make the things I like to make. We should let them do what they want at least a little bit.

"...... that kind of thing?"

"That's the way it is."

Seeing Bertsch smiling softly, Elsa also felt a warm glow.

The car is a 30-seater, with a capacity of 30 passengers.

"It should be able to seat 30 people and carry a lot of luggage.

Jin told Reinhard about his vision for the bus.

"I'm thinking of making it an eight-wheeled bus to cope with rough roads."

The quality of the tires generally available in Japan today is not as good as in modern Japan, so the cost per tire will be reduced.

The quality of Horaijima's tires would not be good enough to be maintained by ordinary technicians.

"I see, so you don't want to use anything too technically advanced?"

"I see, you don't want to use something too technically advanced, do you? ...... but the important parts are made to be unbreakable."

Jin wanted to make the heart part so that it would never break under normal use.

"What are you going to make the frame ...... chassis out of?"

Jin answered, "I'm going to make it out of light silver, because it's too heavy for steel.

"I wonder if it will be 64 light silver."

Unlike 400 years ago, light silver is cheap enough.

64 light silver is an alloy that Jin often uses, which is made of light silver (titanium in the Ars world) mixed with 6 percent aluminum and 4 percent vanadium.

The original light silver is also an isotope of titanium, with atomic number 22, and most of its 26 neutrons have been replaced by magic molecules, making it a good match for magic, but the physical performance has been further improved. 64 light silver.

"It has a ladder-like frame to make it both robust and easy to maintain. ......"

Modern Japanese automobiles are built with a monocoque structure, in which the chassis and body are integrated to provide strength.

This has the advantage of being lightweight, but on the other hand, it has the disadvantage that distortion or loss of a part of the body can reduce the strength of the entire body.

What Jin is referring to is called a , which is used in large vehicles and some special-purpose vehicles (4WD, etc.).

"I think the suspension should be a stacked plate spring."

<, it is used in large vehicles such as trucks and buses because of its simple and sturdy structure and relatively low cost.

It was also used in passenger cars during the Showa period.

The friction between overlapping plate springs also has a vibration-control effect.

After deciding on the main specifications, Jin set to work on the production.

Because of the size of the object, he did not use his usual workshop, but a large workshop he had built behind the institute.

<

Reinhardt was not content to just watch and was eager to help.

"Jin, are these parts enough?

"Yes, that's enough.

"Yes, that's enough." "Shall I do this one, too?

Yeah, can you do that for me?

"Yes, I can."

In this way, the 8-wheel bus was completed that day.

Saki, who came to see the bus, was also impressed.

Saki, who had come to see the bus, was also impressed.

"It will be driven by a special golem, right?

"That's right.

I don't think we'll be able to sell it.

Luis comes over and gives me some advice on how to operate it.

"I think it would be better to rent it.

"I guess so. ......"

Even though the majority of the bus was built with common technology, it was not a good idea to sell such a complete < out of the blue.

They also said that a donation would not be a good way to show our intentions to the people around us. There is a big possibility that people will say, "Why are you giving preferential treatment to only one country?

"You give VIPs a ride when you invite them, don't you?　If we repeat such a thing, people will realize how wonderful this bus is, and then we can think about selling it, right?"

"I see. That's a good point.

"Ha ha, sometimes you have to be useful."

Luis laughs. His friend Reinhardt laughed with him.

Then Lewis said,

"So, if you can make it look like it's a new Machina product that is also being tested, I think that would give us a good reason to rent it at a reasonable price," he advised.

I advised him.

"Oh, that's a good idea!　Let's go with that."

The bus was to be transported to the capital of Klein Kingdom by <> of <> and rented to the Prime Minister or the King.

"I don't know many people in the Klein Kingdom right now. ......"

When Jin wonders what to do about this, Reinhardt gives him some advice.

"It would be easier to have Zion talk to me, wouldn't it?"

"Yes, that's the only way.

Thus, the debut of the new <8-wheel bus> is decided.

By the way, the driver is and the assistant is . The driver is a < and the assistant is an .

* * * * * * * * * * *

"Wow, you made a bus?　You want to rent it out to the Klein Kingdom via me at ......?"

"Yes, that's right."

Jin immediately flew to the and talked to Zion.

"...... You are really rough on the old man, aren't you?"

"Oh, I'm sorry."

Jin hurriedly apologized.

It was true that Zion would be 513 years old this year. He should have retired by now.

"I'm just kidding. "Okay, let's go tomorrow."

"That would be great, thank you."

As Jin thanked Zion, he wondered if he should prepare a for her as well.
