"Now, then, what to do with the permit?"

"Yes. ......"

Jin nodded at the old man's suggestion and thought about what would be best.

"Brother Jin, how about a ring, a bracelet or a pendant?"

Elsa suggested. Jin is still reluctant, saying that it would be fine.

"For my part, I think it should be something unique to each person. It would be unnatural if other people had it. That would make it even safer.

"I see."

"Kuhu, Jin, then I'd like to wear glasses."

Saki was the first to decide. I see, the glasses are only for Saki at the moment, and it is unlikely that anyone else will use them.

"Yes, I like that. Then Saki will have to wear glasses.

"Brother Jin, I'll take this one."

Erza said, showing her hand with the bracelet that Jin had given her to prevent hypermagic.

"Hmmm, I see. Well then, I guess Elsa can use that bracelet.

This is also a good identification tool since no one else can use it.

What about Reinhardt and the others?

Well, we're not in a hurry, so we'll think it over.

"Well, Edgar was born here, so that's fine, but we need to register Aal, Neon, and Noir.

The old man pointed out. Jin thinks, "I see," and considers what to do with Neon, Edgar, and Noir.

"The quickest way is to implant a magic crystal (magi crystal) for identification.

In short, as long as they have Jin's magic pattern, they will be all right. In that sense, this method is quick and sure.

"Well, let's do it this way.

Jin muttered and asked Lao Tzu to bring him a magi crystal. He played with it with his hand,

"Berthe, I'd like to exchange the control core of neon, is that all right?

I asked Bertsche.

"I think it will probably be better than before. ......, but your personality and knowledge will remain the same."

Bertsche thought for a moment and answered.

"Yes, if that's what you mean, by all means. Neon, is that okay?"

"Yes, Mr. Belcher. Reiko's husband would never do anything wrong.

"Thank you. I'll do my best to live up to your expectations.

Jin moves everyone from the cafeteria to the workshop next door.

He lays Neon down on the workbench, cuts off his magic, and begins to remodel.

"Erza, can you help me?"

It is Elsa's turn. She was afraid to take off the clothes of an automata that looked just like Berthe.

"Yes, okay."

Elsa works quickly. After removing the chest skin and other external body parts, it was finally Jin's turn.

The control core is replaced, and countermeasures are taken against the rewriting of slavery magic.

"I'll harden and toughen the skeleton as well.

Jin proceeds with his work quickly and efficiently, muttering to himself, "Oh, wow!

"Oh, oh, oh!

Reinhardt was astonished to see Jin working at his usual speed without any hesitation.

Reinhardt looked to the side and saw Erza watching him intently. Her eyes are serious and she does not look surprised.

Reinhardt feels that Erza has always been watching Jin like this. At the same time, he realizes the reason why Erza has grown up to be a magi engineer.

While Reinhardt is thinking about this, Jin has almost finished the remodeling with the help of Reiko.

Erza has put back the chest skin and reapplied the clothes.

"Okay, that's it. Countermeasures against slave rewriting magic, upgrade the control core, and strengthen the skeleton. That should do it.

The time required is about 10 minutes. The work is made easier by the fact that the shield case and the other parts for the anti-slave rewriting magic are stocked as standard parts.

"Neon, <>"

"Yes."

Neon gets up.

"How are you feeling, Neon?　Are you in control?

Neon performed a self-check procedure and confirmed that everything was fine.

"Yes, Jin-sama, I am doing well. Thank you very much. Thank you, Mr. Bertsche, for your continued support.

Thanks to the increased speed and processing power of the control core, he was speaking more fluently.

"Well, Neon, your pronunciation has improved as well. I'll be counting on you."

"Yes, Mr. Bertsche. Yes, Mr. Bertsche. I'm looking forward to working with you.

Since the essence of Neon has not changed, Berthe will soon get used to the new Neon.

"Okay, Elsa, give Edgar the same anti-slave rewriting magic I've been working on.

"Yes, okay."

After having Reiko prepare a set of countermeasure parts such as a shield case, Elsa started to modify Edgar.

Reinhardt's jaw almost dropped as he watched her follow the same procedure as Jin.

"No, I thought I knew, but Erza, you've grown up. ......"

In a happy, slightly chagrined voice, Reinhardt praised Erza.

"Thank you,......, brother Rai."

Erza also seemed happy to hear that from her respected cousin.

Erza finished the remodeling in about 40 minutes, although it took longer than Jin's work.

For the final touch, Hitoshi inserts a magi crystal into her. <

After all is done and confirmed, Jin smiles at Erza.

"You have remembered well, Erza. No complaints."

Erza's face is flushed and she smiles at Jin's praise.

"Ah, Erza, you can smile with a good face now, too, isn't that good?

"Yes, it is true. Yes, it's true, Erza, you have a nice face.

Both Saki and Bertsch saw her smile and praised her. This made Erza's face even redder.

As for Jin, while Erza was modifying Edgar, he was implanting the MagiRecorder into Noir's chest.

This is because when Reinhardt modified the Black Knight (Schwarzritter) to counter the Unifiler before, it had only a shield structure, and the MagiRecorder had not been implemented yet.

Anyway, now the squires, Golems, and automata can use the warp gate without any problem.

The only ones left are Bertsche and Reinhardt.

"I think a ring would suit the two of you," Jin says.

Jin said,

"Yes, I think so too."

Erza agrees.

So Jin and Erza decide to make a protection ring, or rather a .

"<>".

Elsa is in charge of making the ring, including the design,

"<>"

Jin writes in the Magi Formula.

The previous protection ring was a round ring with a half-round cross section, but this time it is different.

On the upper surface, there was the Randall family crest, a facing levee (a lion-like animal), and on the lower surface, the names of Reinhardt and Bertsche were engraved.

Reinhardt rolled his eyes again when he saw it.

"Well, as I said before, Erza, you have become a good Magi engineer. If there is anything you lack, it is experience.

"Thank you, brother Rai."

Erza thanked him again, her cheeks flushing with gratitude at his words of praise.

"I didn't know you had such talent. I should have taught you."

Reinhardt shook his head and reiterated, "If you had, you would have met a different fate.

"No, it's no use saying that if you had. If you are happy now and will be happy in the future, that's the best.

Elsa presents the rings to Reinhard and Bertsche. Reinhardt himself fine-tuned the size of the ring.

"Thank you, Jin, Erza. I will treasure it."

The ring, made from high-quality magi crystals of all attributes, shone in rainbow colors.

"Now, all of you can use the warp gate to come here. Still, for the time being, please follow the old man's instructions.

I understand.

I understand.

"Yes, I understand."

Reinhard, Bertsche and Saki nodded in agreement.

"Well then, Saki and Reinhardt, you can use this workshop for now."

The first workshop is 8 meters long from east to west and 15 meters long from north to south, so there is enough space for the three of us, including Jin.

If you need a room, there are plenty of vacant rooms on the third floor.

Jin felt satisfied that he had finally come a little closer to his predecessor's vision of a research institute, in other words, a sanctuary of magical engineering (magecraft).
