　An effective way to use the shell of the gigantopod. This was the theme of Saki's current research.

　There is a large stock of them in Horai Island.

　After all, she had killed five 50-meter-long individuals in the past, and most of their shells are in her stock.

　In addition, we have killed 1 ...... smaller individual, which is 10 meters long even if it is small. The quality of the shells themselves does not differ.

　There is no difference in the quality of the shells themselves, only in their thickness.

"I wonder if I can be of more help.

　Saki's wish was "I wonder if I can be more useful.



　When Jin had developed the <, he had compressed the shell of a gigantopod (gigantopod).

(In that case, a new material without direction was made, but there was no ...... use for it.)

　I remember that it was hard, heavy, and difficult to process, and was inferior to hyperadamantite as a molecular compression material, so it was used only for that purpose.

　Saki seems to be researching materials that are easy to use without such molecular compression.

"Hey Jin, can you tell me about normal biomaterials?"

　Saki, of course, is well informed, but Jin's explanation might make her realize something she hadn't noticed before.

"Sure."

　Jin readily agreed and began to explain.

"Bio-based materials do not work well with engineering magic. Furthermore, most of the engineering magic does not work on them when they are alive.

"Yes, that's true."

　Jin nodded and continued his explanation.

"The main reason for this is that the free magical element (ether) flowing in the living body interferes with the effects of magic. However, if something has fallen out of the living body, it can be processed by engineering magic.

That's what's so strange about it, isn't it?

"Indeed. It can't be explained simply by the fact that they are alive.

　If the free magical element (ether) flowing in a living body interferes with the effects of magic, and this is all, then the <> should be able to make engineering magic work on a living body, but it still doesn't work.



　The <> is a device that puts the free magical elements (ether) within a certain range under its control and blocks the opponent's magic, and if Jin uses the device he created, the free magical elements (ether) within the area of effect will obey his magical power.

　In other words, only Jin can use magic within the range of this .

　However, even if the is used on a living body, the engineering magic does not become effective.

"However, engineering magic will be effective on those that have been detached or fallen off from the living body.

"Kuhu, that's a subject for further research.

　Jin decided to leave this topic for now and continued his explanation.



"The ease of processing this engineering magic depends on the biomaterial. To be more precise, it seems to depend on the strength of the original organism's magic and how much residual magic it has.

"Interesting.

"So, the shell of a gigantopod can't be processed by a second-rate magecraftsman, can it?"

Is that so?

"Is that so?" "Yes. My feeling is that the shell of a gigantic centipede is especially difficult to process.

"I've made knives and shields out of it."

　So in a way it's natural that Saki would be interested in this material, Jin said.

"Well, ...... I'm getting more and more interested in it."

　Saki, for his part, has spent more time researching the material ...... that was more commonly available than other materials ...... 350 years ago, Saki had put the shell of the gigantopod on the back burner.

　In any case, even if there were a large amount of this material, it was only in Horai Island, and it is unlikely to be available to the general public, so it is not surprising that it was put on the back burner.



"As far as I'm concerned, if the difficulty of processing <> is 1, the difficulty of processing <> is 2, and the difficulty of processing <> is 3. <> is also 2. <> is about 10.

"Hmm, so it's like that."

　Now that she had quantified it, Saki seemed to have some idea of what she was talking about.

"But the shell of a gigantopod has about 200.

"What?

　Saki was astonished at the literally different order of magnitude.

"That explains why ...... gin is so hard to process. I mean, who else but Jin can process ...... them?"

"Not just top-notch, but top-notch technicians."

　Saki's face became even more difficult.

"Well, I'd like to unravel its secrets, but I guess I'll start with the effective use of materials ......."

　Saki says, "We have plenty of time, so let's start with what we want to do first.

"Then I have ......1 an idea."

　Jin opened his mouth.

"I don't know if it will work or not, but we first crush the shell with its magic power removed. Then we harden it in some way and pass the magic power through it again.



　In short, this is the < approach I was imagining earlier.

　Carbon fiber is often used in a directional manner (e.g., in layers), while short glass fibers are used in a more uniform manner.



　Saki was intrigued by this idea.

"Hmmm... Shall we harden it with magic resin?　Or better yet, we could use GSP.

"Yes, that's right."

　We decided to use a material that can be strengthened by magic power, namely, ground spider resin (GSP).

　The shells can be crushed by human power.

　Since it would lose its effect as a fiber if it is too fine, we limited ourselves to crushing it coarsely.

　We can then mix it evenly into the ground spider resin (GSP).

"Let's change the mixing ratio and check its properties."

　Saki seemed to be planning to conduct an experiment to find the best mixing ratio.

"Yes, that would be good.

　Jin agreed.

"Kuhu, from here on out, it's just me and Smith99. Jin, thank you for your cooperation.

"I'm looking forward to it. I hope it goes well.

After the discussion with Saki, Jin and Saki went over the results of the experiment.

　Erza was not at <>, probably working on her own research......healing magic or plant magic that she had mentioned earlier.

"...... I think I'll take a bath."

　Jin decided to take a soak in the hot spring before dinner.

　With a mini Reiko on his shoulder, Jin went to the bathroom.



"Ah, this is nice hot water.

　Jin relaxes in the hot spring. He feels that his mental exhaustion is being healed more than his physical exhaustion.

Father, let me wash your back," says Mini-Reiko.

　Reiko says, but I can't seem to reach his shoulders.

　I thought so, but then she used the "force field generator" to float up and rub my back properly.

　Moreover, the degree of force was exquisite, just like the original Reiko.

"Thank you."
