Magi Craft Meister

Since the story of "Go Research" played out, we were to eat together at lunch.

When we go to the cafeteria together...

Oh, Jin-sama.

I'm free here.

Well then, don't hesitate.

Lower Eisker, the director of the "Aeronautical Research" department, came to the cafeteria one foot ahead of the other.

It's been a long time, Jin-sama.

"Hey, uh, Ciel. That's Tiner-kun."

"It's a pleasure for me to remember."

There were also members of Ciel Ajour, Tainer Bito, and the "Aeronautical Research Institute", and when they were seated together, they became large bands.

Reiko and Cher stood diagonally behind Jin and Arnold, respectively, without taking their seats.

"... but, Arnold, you can eat..."

"Yeah, I have a good sense of taste."That said, there is no need for digestive absorption, so it breaks down into atoms in the body and aggregates for other uses. "

What are the other uses?

Apparently interested, Ka 'chair asks Arnold a lot of questions.

"For example, if you extract the sugar and aggregate it, it becomes icing sugar, and if you extract the salt, you can extract the salt."

Ah, that's right.

"...... You really have a good body......"

Meanwhile, Ren was questioned by the "Aeronautical Research" members.

I heard it all at once, but you discovered an unprecedented type of thruster?

As expected, the director of the [Aeronautical Research] department, Lower Eisker, was a pretty early ear.

As for the magic rocket engine, there should be an official announcement soon, so it would be good to affirm it.

"That's right." I think it will be officially announced soon. "

It was only Jin who had to answer.



After lunch, Jen and Arnold went to "Go Research" again.

"What are you developing now?"

Jen asked, and Groma replied to this.

"It's an underwater golem."

Huh.

"Of course, even a normal golem can act underwater, but what we are developing is a body that floats in the water like a human."

I see.

"Shipping will be more and more developed in the future.If that happens, there will be an accident at sea, so we will send a rescue team.It's a golem to use for that. "

That's right. Peaceful use, isn't it?

As for Ren, he was very much in favor of it.

Looking at Jen like that, Eira started to consult with her.

"The question is, how do you float?"That's why Groma and I are arguing. "

Eila explained that the debate was whether to make the specific gravity of the golem almost as "floating" as the water, or "floating" with a propeller such as a "magi water jet" that was sturdy and heavy.

For the specific gravity 1, on the other hand, it is not necessary to do anything special in order to "float". On the other hand, it is necessary to use light materials, and it seems that there is anxiety about the strength.

If you use a thruster, it has the disadvantage of sinking if the thruster fails, but there are not many restrictions on the material.

It is commonly necessary to choose materials that are resistant to sea water.

I want to make it robust because it's better to have strength for rescue.

"I think so, don't I?"

Aira is a strength-first, floating propellant.

But as a technician, I'd like to make a specific gravity of 1.

Jin-sama thinks so too, doesn't he?

Groma wants to have a specific gravity of 1 without the use of an extra propellant.

Whose side is Jin in the end?

Jen answers with a smile.

"I want to create something that satisfies both."Even Eila doesn't want to make [heavy], does she? "

That's right.

In that case, it's not bad to pursue both strength and lightness.

"I'd like to do that if possible..."

In this case, for example, it is bad if the specific gravity becomes 1.1.

Because you have to float in the water without any aid.

"Given the power, I really want to use metal in the skeleton."It will inevitably get heavier. "

That's for sure.

If we also use metal for the exterior, the specific gravity will be about double no matter what.

I've been thinking about it for a while, Eila said.

Have you tried your lifejacket?

For once, I couldn't do it for humans.

I had the ability to attach external equipment such as a "floating wheel" and a "lifejacket", but it was said that there was not enough buoyancy for humans.

Huh? It's difficult.

"There are only special materials left..."

It seemed that using a material that could be enhanced by magic would make it light and strong.

But...

Jin-san, that's a bit harsh, too.

When I do, I get a mess out of the cachaise.

"There is a premise that mass production is possible..."

"That's tough."

Materials that can be enhanced by magic are generally expensive.

"Isn't that right? That's why we're arguing."... so what's Jin's opinion? "

"Hmmm..."

After a little thought. Jen's answer is...

We need to develop inexpensive materials that can be enhanced by magic power.

was.

Haha!?

"Hmmm..."

"Is that so..."

Eila, Groma, and Ka 'chair put their thoughts on a short note.

"I think we'll be short on [development period]." What about you? "

"Half a year has passed, and there are just under four months left."

"I see.... even if you spend two months developing materials, you won't get any change."

If Jen leaks a murmur to the information from the Ka-chair,

Jin is the only one who can afford such a schedule.

I was told that.

Arnold joins us there.

What? It's a cheap material that can be enhanced by magic power?If the level of enhancement is low, then there is. "

Huh?

It was a daily tea affair to run short of supplies during the war.

Well, what kind of material is that?

"It's a stone."

Yeah?

"Corundum, to be exact."

I see.

Stone... In addition to "hardness", "toughness" is also important for the "toughness" of minerals.In other words, "breakability, break-resistance".

Diamonds have a Mohs hardness of 10 and the "hardness" is the highest, but they have a surface that is prone to cracking, that is, a "split (hedge) surface", and "toughness" drops slightly.

The highest classes of 'toughness' are 'corundum' (including rubies and sapphires) and 'jade'.

The morse hardness of the jade is from 6.5 to 7, and the corundum is 9.

In other words, Corundum is more "sturdy".

"Corundum is dinner... no, it should be quite a harvest in the Cellulore Kingdom right now, so you just have to magically handle it."

"It's been helpful!" Thank you, Arnold! "

"Thank you for the information, Lord Arnold."

"Arnold, thank you for the tip."

Kacha, Groma, Eira and the others expressed their gratitude to the mouths.
