Jin decides to perform an aptitude test on Freddy.
"First of all, we need to do . Let's find out how well he can do this.
This is how it started with Erza and with Reinhardt.
"It doesn't matter if you can do it or not, just learn how to do the <>."
Jin taught Freddie how to do transinfo.
"Uh, like this, right? ......<!"
"<>!"
Jin asked Reiko to <> it so that he could know the degree of her aptitude.
"Father, I think Freddy can make it to level 3."
"Oh, that's good news.
Erza was level 3 and Reinhardt was level 2. With subsequent training, they have grown up to level 8 and 7 respectively.
Freddie, on the other hand, had proven to be proficient enough to use level 3 at this point in time. Jin was pleased that it was worthwhile to teach him.
And so, the training began.
"First, the basics. < function?
Yes.
Yes. Then, let's have you make a true sphere from this bronze ingot.
Training in forming is not only training in the manipulation of magic power, but also in one of the most important aspects of engineering magic, the ability to grasp space.
Erza has improved through training in making pen nibs.
"Jin-sama, should I practice too?"
Rubina asks.
"Yes? How long have you been practicing, Rubina?"
"What? I haven't."
"Yes. ......"
Jin was surprised,
"Jin-sama, on Onogoro Island, we have a different curriculum.
Marikka explained.
"Really, what kind of curriculum?"
"Yes. Well, let's say that instead of actually using magic such as <>, we simulate it in our brains.
According to Marikka's explanation, they wear a headset similar to that used to control a doppelganger, and perform various operations on it.
"I see. I see. I guess that would be a good training for the doppelganger style operation.
"Yes. I mean ......, it was Jin-sama who invented this ......."
"Me?"
Jin said he invented it when he was about 50 years old.
"I see. I see. That way I can concentrate on my training in a shorter period of time.
This training method was originally invented by Jin in the past ...... from the future ...... present time. The present Jin immediately understood its usefulness.
"But ...... this one is better in that you can actually see it with your eyes and touch it with your hands."
Ultimately, it remains to be seen which one will develop a person's talents more.
"So, Rubina and Gulina, try it too."
"Yes?"
"Yes."
The two listened to Jin's words. Maricka had long since outgrown that stage, so she was not included.
"Well then, try to make a true sphere out of this bronze ingot.
"Yes. <
Forming.
"Oh, wonderful."
Both of you have created a perfect sphere in an instant.
"Now, give me two of the same size."
"Yes. <
"Okay. Then, four.
Up to this point, both Rubina and Grina have done this without any problem.
"No, no, Master Jin, you can't use these two as a standard."
Jin said this while looking at Rubina and Gulina, but Marikka, who was in a hurry, denied it from the side.
"...... No, average doesn't mean the world, it means ."
"Still, these two are top class."
"...... I understand."
Marikka's advice made sense to Jin. Then, Rubina called out to him.
"Hey, Jin-sama, how many true balls can you make?
Gulina joined in,
"Let me see how you do it!
"Let's see how you do it!" she says. Freddy, who was practicing, was curious, and even Maricka's eyes lit up.
"...... got it. Reiko, give me a bronze ingot too.
"Yes, father."
Reiko placed a huge ingot in front of Jin. It was five times larger than the ingot Rubina and the others were handling. Everyone looks at it with rounded eyes.
Here we go. ......<>"
In an instant, the bronze ingot changes shape and becomes <<40 pieces>> of a perfect sphere. Some of them rolled off the workbench, and Reiko picked them up.
"Wow... ......"
"This is so ......"
"That's too much!"
"......"
Rubina, Grina, Marikka, Freddy and the others were half-amazed and half-surprised to learn of Jin's abilities.
"They're all the same size, beautiful balls. ......"
"That's what Jin-sama is all about. ......
"I'll do my best!"
Freddy, who had been wondering in a corner of his mind why he was doing this, suddenly seemed to be motivated by Jin's amazing skills.
* * * * * * * * * * * * *
The day ended with a full day of <> training with lunch in between.
Not only Freddy, but also Rubina and Grina were suddenly motivated, and for some reason even Marikka joined in the training to make a true sphere by <>.
Meanwhile, Ellis watched his grandchildren with a beaming smile from beginning to end.
And the results were good.
Maricka can now make 18 spheres at the same time, Rubina 14, and Grina 12, which is a remarkable progress compared to the beginning.
And Freddy has the highest increase with 6 true balls.
"So this method works after all, doesn't it?"
"Yes. Probably, the overall ability will be improved through the grasping of objects in three dimensions and the mastery of magical manipulation.
Jin explained his theory to Marikka.
"I see. ...... That's just as Jin-sama said."
"But, why did I recommend simulation before?"
Isn't it because simulation has its advantages?
Well, what are the advantages?
"Well, I think it's probably that you can improve your skills in a short period of time."
Marikka said that the previous Jin had proposed this method when there was a need to train magicians (magecraftsmen) anyway.
Hearing this, Jin guessed that it was probably a time of maturity before the rise of the .
It was probably an efficient training method proposed by Jin when there was not enough manpower.
However, Jin imagined that somewhere it was distorted and transmitted, and only <> remained.
