Magi Craft Meister

"Elsa, I need to talk to you"

To Jen's words, Elsa replied with a smile.

"... I know. You're gonna replace it with" Doppel, "right?

"Big Win"

Jen gave Elsa a laugh of bitterness.

"I want to hurry up and find out what that material is. I can't help but notice the Phantom over here."

"Mm, I get it. Go away."

"You're not going. Elsa, come too."

"Huh?"

"I don't know what's out there, so you should stay with me"

Even as Jen, I have seen a lot of patterns in cartoons and novels where she is overconfident that she will be fine and will be grabbed by her and her family.

"Mm, okay."

So Jen, with Elsa and Reiko, was engulfed in the magic of "Invisibility" and headed to "Conlon 3".

At the same time, there was also a 'elm' with shards of armor.

"Conlon 3" has two guards attached, but has not been noticed thanks to "Invisibility (Invisibility)".

Jen, who received a fragment of his armor from "Elm," flew silently to Penglai Island at the transfer gate (Warp Gate) inside "Conlon 3".

"Welcome home, Master (My Road), Master Elsa"

As usual, your voice greets you.

"Send me and Elsa's Doppel instead."

"Okay."

After giving instructions to you, Jen hurried to the workshop. Elsa and Reiko follow suit.

Place the sample pieces of armor on the workshop workbench and finally start analyzing them.

"Is this the piece of armor? That's light......"

My first impression is that it's 'light'.

"Really, light"

Elsa also tried holding a sample and was surprised by its lightness.

"Well, this metal..."

Among Jen's memories in modern Japan, there is one.

It did not have to be 'analyzed' to be judged.

"This is foam metal."

"'Foamed metal'?

Jen explains to Elsa, who has asked questions about parrot returns.

"Oh. I just heard it, too."

It is a material that was still under development even in modern Japan, where Jen was present.

"I only know enough to use gas and stuff to foam aluminum and titanium"

And take a serious look at the sample in front of you.

"The material would be titanium...... light silver. And there are countless tiny holes. So it looks matte."

I don't know how I made it, Jen told me honestly.

"Even Brother Jin doesn't know?

Elsa looking unable to hide her surprise.

"Yeah, but it's not like we can't make the same thing."

There are several imaginable formulations, which I also added.

"For example?"

That's what Elsa wants to know. Jen left her body behind the back of the chair and began to talk about herself.

"First of all, the structure just needs to be empty of countless little holes. I mean, you can make 'little bubbles' out of metal."

"Mm, I know."

"The question is how do we do that? The first thought is to generate air bubbles in the metal in the melted state"

It is quite hot when melted, but "softening" is possible at room temperature.

"... Indeed"

"But normal air bubbles wouldn't make it this far into a fine foaming state. So as another possibility..."

Make bubbles with magic, Jen explained.

"Well, then, depending on how you do it, you'll also be able to do some pretty fine bubbles."

"Oh, I see. That's Brother Jin."

But Jen shook his head.

"But it looks like this sample was made another way..."

And he put his arms together, and Jen stared at the sample.

"But Brother Jin, isn't this weak?

To Elsa's voice, Jen reminded her that there was something to be done before she could think about making a method.

"Oh, sure. That's why they cracked and broke."

"So what did you make this stuff for?

"So is that."

The advantages of foaming metals include lightening and increased heat resistance (some alloys), but they cannot be made into armor, Jen thinks.

"Sure it will absorb the shock..."

That's all. Overall, the defense would be low.

That's where I get additional information from you, old man.

"Master (My Road), from" Elm "who was at the scene, there is information that the carriage loaded with that armor is also loaded with barrels filled with some heavy liquid. the weight of that liquid… with the presumption that the specific gravity would be liquid metallic like '

"What!"

To new information, Jen rises from the chair.

And he lowered his back again, and at that time he had a grin on his face.

"Brother Jin? What's the matter with you?

"... with the information I have now, I think I understand the use of this' armor '"

"Huh?"

To Elsa tilting her neck, Jen explains to teach slowly.

"Foam metal and liquid metal. Have you noticed anything in this combination?

"... uh, stain it?

"Yes."

Jen nodded loudly and showed it.

"Perhaps the original performance will be achieved by staining this foamed metal with liquid metal."

"The original performance, what?

Jen smiled back at the question.

"That's what I don't know because I don't have that liquid metal. But I made about two guesses."

Let me hear it.

"Absolutely. … First, strengthen your armor"

"Hmm, I know that"

"I guess."

Foam...... Anyone would associate it with a perforated metal and a 'liquid' metal.

"I think that would allow for a dramatic increase in intensity"

At least, that's why Jen didn't see the material of the armor worn by Phantom, number 41.

"If it's not an alloy, it's not plated. 'Stained' state, so unparalleled in appearance"

It is only natural that we could not judge it in the long run.

"But perhaps, after prejudging, I wonder if another conjecture is the original purpose."

"What's that?

"That's one of the things we've been chasing since before this --"

Jen hangs up the words once and then goes on again.

"Fluid deformation power. Fluid foam drive."
