It looks like a log house from the outside, but the inside has been modified considerably.

"Oh, this is ......."

"So there's a transfer magic circle inside. Where is this connected to?

Jin answers Chell's question.

It's Fort Lutgula. We have temporarily installed the same facilities over there as here, so you can easily come and go.

Both of them were pleased to hear this.

"That's wonderful!

"That's just what Jin-sama deserves!"

"Yes, well, now that you can come and go easily using this, I need your help with something."

What is it?

"Actually, ......."

Jin D explained about the request from the King of Selroa.

<

This is a legitimate request from the king of .

Chelle concluded.

"I see, you mean the redevelopment of the first underground base.

"Oh, you mean to call it ?"

"Yes. The creators also called it "Underground Base 1".

"I see. So, first we need to repair <>. ......

"You are concerned about becoming a subordinate of Jin-sama, aren't you?"

Yes.

"Does His Majesty the King know about that?"

Yes. I explained it to him briefly when he asked me to do it.

Then why don't you become the master and change the order of precedence?

"I guess that's the only way."

Still, since Jin is , he would be treated as > and would have the highest command authority.

"Then, why don't you add some security to prevent Jin-sama from listening to you unless you enter your password?"

"Yes, that would be nice."

Jin thought that it would be dangerous not to listen to him completely, so he thought it would be a good idea to add security to the extent that it was not a <>.

"Yeah, I'm glad I asked. Chel, thank you."

"No, you're welcome."

"While we're at it, what should we do about the equipment and golems other than <>?

By "what should we do", I mean, should we keep them as much as possible, or should we rebuild them in his own way?

"Well, my creator always said that <> was a failure, so why don't you do as you please, Jin-sama?

"Is that right?"

Yes. Yes. His Majesty the King has asked me to do so.

I see. Thank you.

You're welcome. ...... may we observe the refurbishment?　We won't disturb you.

"Yes, of course. You can come and take a look when it's convenient for you.

Thank you very much.

Thus, Jin now had a clear idea of how to renovate .

* * * *

Jin himself, who was in Horai Island, started to discuss with the old man based on what he had just discussed with Chel.

"So you are saying that <> should be renovated by all those who have control cores including <>, right?

"That is true.

It will take some time, but technically there is no problem.

The immediate problem is <.

"I thought Chell had a slightly different kind of security."

"What do you mean?　What do you mean?

"Ah, so that's how it works. That's right. ...... but as far as I know, you can remove the limiter only by your own will."

Even that Elena is able to release the limiter by herself in a crisis.

"...... Let's go back to the story. I'm thinking of a hardware security device that I'll install after I've modified <>, an add-on that interferes with my magic patterns, what do you think?"

>

"Yes. I don't recognize it, so I don't recognize it as either."

<

"I see that too ......, so only the security can be activated afterwards."

"Yes, that's right. ......"

A simple switch is out of the question, because anyone can press it.

On the other hand, if it requires complicated operation or is placed in a place where it is difficult to operate, it will be inconvenient in case of emergency.

"Father, would you like me to take care of it?"

At this point, speaks up.

Since Reiko herself is attached to Jin D, Jin himself has a mini-Reiko attached to him.

"Reiko?"

"Yes. If you make sure that I can switch security, it should not be a problem in the first place.

I see.

It's unlikely that Jin would visit such a facility alone. He would almost certainly be accompanied by Reiko.

So it was an interesting point of view to set up a security system that only Reiko can switch to.

"Yes, that's right. How about expanding it a little more, so that only Golem and automata in Horai Island can switch?

There is a very small but non-zero chance that Jin will visit with someone other than Reiko ......<> or <> or Anne for some reason.

"That's all right. The magic pattern is the same as mine, it's the second stage. The first stage before that is to move very heavily.

In short, it is a switch or lever too heavy for a human to move.

<

It is a switch that has Jin's magic pattern and can only be moved by a monstrous force.

"Ah, there you have it, <>."

<

"Good."

Now that he had the old man's approval, Jin prepared the materials and finally began to consider reconfiguring the magic brain.
