He put the mini Reiko on his shoulder and started walking toward Saki's house.
Since the house had been moved, Saki seemed to be doing some things in the laboratory in her house, not in the laboratory.
"Saki, are you there?"
Jin came into Saki's laboratory and casually called out to her in his usual tone.
"Hey, Jin."
Saki was conducting some kind of research with Smith99 as his assistant.
"I heard that you are working on biological materials.
When Jin asked this, Saki leaned forward as if she had just heard what he wanted.
"Yes, that's right. Here, look at this.
Saki showed us a fragment of the shell of a Gigantopod.
"The shell of a Gigantopod is weaker than the leather of an ancient dragon, but it is a material with various unusual properties.
It is strange to say that ...... before he was born, but 400......35 I didn't do enough research on it 400 years ago," Saki said.
"Just as well, I'd like to hear Jin's opinion too."
Saki, who had completely stopped working, offered Jin a chair and sat down again.
"About 350 years ago, I was studying how the shell of a gigantopod could be so strong. The conclusion I came to at the time was that it was made by layering the tissue and channeling magic power between the layers to improve the effect of the reinforcement.
"I see."
Saki said, "As a result, the magical power strengthened it remarkably and it became so strong.
"Of course, that's not all. The surface gloss and reflectivity also reflect physical magic.
Even laser beams are largely repelled.
"It's a different kind of strength than the leather of the ancient dragons."
"That's true."

But the shell of a gigantopod becomes extraordinarily hard.
"To return to the story, if you remove the magic power between the layers, you see?
Saki peeled off a thin piece of the shell in her hand and showed it to me.
"This is a sample with the magic completely removed, but you can peel it off by hand like this. It looks like mica, doesn't it?"
"Oh, this is ......."
Jin was impressed.
As a side note, this information is actually known to Jin's original (400-year-old Jin). The original Jin (400 years ago) knows this information, but the duplicate Jin does not.
Saki is aware of this, which is why she is explaining in this way.
"I have concluded that by strengthening the magic in layers in this way, it has a great resistance against vertical forces.
"I see, that makes sense."
The secret of the hardness of the shell of the gigantopods has been revealed.
Jin was reminded of , which is used in modern Japan.
FRP is a composite material in which tough (mainly high tensile strength) fibers such as glass fiber and carbon fiber are inserted into plastic to increase its strength.
Plastics have a low elastic modulus and low resistance to deformation. This composite material was developed to improve this situation.
Jin thought that materials strengthened by magic power might be similar to this.
And there are two ways of compositing with such fiber materials.
One is to evenly sprinkle finely cut fibers. The strength of the resulting material is not directional.
The other is to infiltrate the plastic with directional fibers, which significantly increases the tensile strength in the direction of the fibers, but weakens the tensile strength at right angles to the fibers.
The shell of the gigantopod reminded Jin of this.
"I want to find an effective way to process and use this interesting biomaterial, that is, the shell of the gigantopod."
As it is, only a limited number of technicians can process the material.
And if the shell is processed in such a way that it can be processed by ordinary technicians, the strength of the shell will be reduced.
