The next day, the 29th, Jin and Erza jumped to Horai Island after breakfast.

For a moment, Jin wondered about the master not showing up at the castle, but such a thought flew away when they arrived at the institute.

"Now, let's continue where we left off yesterday. Elsa, is there anything you don't understand?

"Yes, I got most of the methods figured out yesterday. Now I just need you to tell me what materials to use.

Materials for the mascot. Since everything is available here in Hourai Island, it seems that it is rather difficult to decide.

"Try to make it the same structure as an automata.

"What?"

Jin told him that he could make a simple skeleton, fill it with cotton and cover the outside with magi silk.

There is a doll called "stuffed animal. It is similar to a stuffed doll, but by adding a skeleton, you can make the doll assume various poses.

The image he had in mind was a one-third scale doll.

"Sounds interesting. The fact that it can be posed is novel.

Apparently, the dolls of this world had not gone that far.

Jin gives her some light silver for a skeleton, and plans to watch Erza for a while.

"I'd better think about the head."

"I'd better think about the head ........." "Oh, okay."

Knowledge acquired through transinfo is not something that can be put to use overnight. It is a path that Jin has also taken.

At first, you feel like you have a book in your head, and it takes time to turn the pages. However, once you have used the knowledge, you can use it smoothly the next time.

The same is true for Erza, who only realizes what she is doing when Hitoshi tells her.

Jin, who has experience in the field, took the lead in drawing out Erza's knowledge.

"I think four to five heads would be good.

Elsa also had a good idea of what she wanted.

"I want the joints to be neck, shoulders, elbows, wrists, waist, groin, knees, and ankles.

"Yeah, that's good, right?"

"Yeah, that's fine." "What about ...... and Boroujoint?　I think it would be good.

Jin nodded in agreement. Actually, this is a kind of rehearsal for making a golem or an automata.

"Let's say it's about 130 centimeters tall, and it's a third of that, so ......4 5 centimeters."

That's a reasonable size for a doll to be displayed in a room.

Jin nodded and let him continue.

"The skeleton is ...... about this size. "

"Oh, you're getting good at this."

In one step, Elsa has formed the mascot's skeleton, its basic shape. There are no joints yet, but the fact that the head and limbs are in place is a sign of progress.

"Really?　I'm so happy."

Erza smiles and continues to work on it.

"<>. <>. <>"

Joints are formed, and fingers and toes are shaped. Jin nodded silently.

"Now we attach the padding to it. ...... I'd like to do that by hand a bit."

Not everything has to be done by magic. Jin affirmed that as well.

Thus, with Jin watching over her, Erza had created the basic shape of a doll in only about 30 minutes.

Even though the doll is one-third the size of the original, this is an astonishingly fast process. This is because she had a clear idea of what she wanted to create.

"Now I just need eyes, hair, and clothes.

This is a matter of taste, so there is no need for Jin to come in.

"...... then, I'm going to go do what I do, call me if you need anything."

Jin then took Reiko and went upstairs to the laboratory.

"Reiko, how are you doing?"

Jin immediately asked Reiko how the tactile sensing device he had installed in her was working.

"Yes, as you said, it did not affect its operation. And yes, I can certainly feel the <, but the response seems to be slow or delayed.

"I see. ......"

Delayed sensation is fatal to high-speed operation. Jin thought about the causes.

One of them would be the flow of magic control (Magi sequence) that he had built for the first time. There is still room for improvement in efficiency.

"And then there is ...... clock up, I guess."

Since the response of the magical skin is immediate, Jin concluded that the delay in perception is probably due to the time taken for reading and recognition.

"Hmmm, at the moment, even if we increase the efficiency, it would be good to double it."

Jin muttered as he reviewed the flow of magic control (magi sequence). <

However, Reiko can move nearly a hundred times faster than a human when the time comes.

"Is there any effective way to increase the speed ......?"

Jin crossed his arms and thought.

He thought and thought and thought.

"Let's do it little by little.

That was the conclusion. In other words, instead of trying to solve everything with one thing, we should try to speed up each part of the system in the spirit of "Every little bit adds up to a big pile", and as a result, aim for further speed-up of the whole system.

"First of all, how fast is the transmission of magic power?

Jin asked himself, "I had not paid much attention to this before, but what is the speed at which magic power is transmitted through a magecrystal?

Jin recalled that in an electronic circuit, the speed at which electricity travels, i.e., the speed of electromagnetic waves, is approximately the speed of light (......).

The speed of sound waves changes depending on the medium. Light is the same. Then, what about magic power?

The answer is <. This is due to the fact that it has been observed in the past that magic power is slightly deflected by magic crystals (magicrystals), which are in the same family as magic power.

It is the same as a prism. It means that light slows down in a material with high density (or more precisely, refractive index). The same seems to be true of magic.

"So, I guess it depends on the magic crystal (magicrystal). ......"

At this thought, Jin remembered Saki's face. What would Saki think when she was faced with this kind of problem?

"......It's possible that I'll bring her to Horai Island sooner or later."

Reiko reacted to the words that came out of my mouth.

"Father, are you talking about Saki?"

"Oh, yes. You heard me."

"Yes. ......Saki-san sometimes thinks a little bit like your mother. It might be useful for your father's research."

Reiko says something unexpected.

"Is that so? I'd like to bring Erza to see you soon. ...... Well, first we'll go to Kunlun Island, I suppose."

I'm sure you'll be able to find a good deal of information on the subject.

Putting Saki aside for now, Jin returned to the idea of improving the processing speed.

"Speaking of magi-crystals, what about eladolite?

This ore is still a mystery. Its effect is said to be the amplification of magic and magical power, but that is not accurate.

Nothing can come from nothing.

"I guess it would be better to say that the incoming magic power is amplified by the magic power that is nearby."

Using the mana of the surrounding magic (the easiest to use is the mana of the magician himself), magic with a power of only 1 is increased from 10 to 20. This is the characteristic of eladrite.

It does not mean that the mage can use magic beyond his own ability, but it only amplifies the effect.

"I see!"

Suddenly an idea flashed through Jin's mind.

"If the magic generated by the tactile sensor is enhanced by the amplification effect of the eladolite, it will be easier to perceive, won't it?

Whenever he has an idea, he immediately tries it out.

He takes out the < attached to Reiko's body, and tries to incorporate Eldra Light into the preliminary stage of perception.

Since this is just to see the effect, no other modifications are made. If I do so, I will not be able to tell which of the modifications has the effect.

"Well, Reiko, how about this time?"

Reiko rebooted and tried to grab and lift the tools and magi-crystals that were there,

"Father, it's amazing. It's much clearer now.

He told me that it had a great effect. I guess he meant that the reading, which was too minute and took a long time, had been eliminated.

"Oh yeah!　I'm amplifying it by a factor of roughly 10 now, is that enough?"

"Yes, I think it's just one step away from full power and it will still feel good. Shall we give it a try?"

Jin is satisfied with Reiko's answer.

"No, not now. Then I'll take it off again. Then we will review the magic control flow (magi sequence). Then we can ......."

Overall, it should be possible to deal with Reiko at full power.

Jin's expectations grew.
