On October 17, after breakfast, Jin told the members of the Jin Family that he was going to search the basement of the <>.

"We've already analyzed most of the <>."

"Huh?　How did you exchange information with them?"

"Oh, Saki didn't know?　There was a connector on the back of his head.

Jin explained, "There was a wired magic power conduction line extending from there.

"I see. So you're going to investigate the base ......, or rather, the ruins, today?"

"That's what I mean. I'm thinking of doing it with two ......<> and ten land troops."

"You're not going to use a doppelganger?"

"Well, I don't know.

If we switch the controls when we see something interesting, it's almost the same as seeing it with our own eyes.

"I'll send someone."

I knew you'd say that, Jin.

I'm sure he would.

Yeah.

Jin scratched his head in embarrassment at what Reinhardt and Erza had also said.

* * * * * *

< by transporter, so the time required was almost zero.

And since this is , access to the site is basically unrestricted.

The reason why the word "basically" is added is that some ruins are managed by the national government.

And <> is a site where there is no administrator. In other words, it is a site that is not known to the general public.

There is no problem to go inside.

Jin D. and his group set foot in the ruins with <> in the lead.

"This area has already been surveyed, hasn't it?

Jin D., who was walking in the middle of the group, said. Jin D. was now in direct control.

"As I recall, the entire upper ground level has collapsed, and the remains have been excavated up to the second basement level.

"That's right, Master."

The old man explained through the mouth of Land 21 with consideration for Jin who was piloting Jin D. "Until just a few days ago, there were two underground levels," he said.

"Until just a few days ago, it was thought that the ruins were only up to the second basement floor, but the old man has discovered that the ruins extend from the fifth basement floor to the tenth basement floor by tracing the magical power conduction lines with a . The old man's tracing of the conductive lines of magic with the Peeper telescope has revealed that the ruins are located from the fifth basement floor to the tenth.

Now it was Rand 21's turn to explain.

"It seems so."

While we were having this conversation, two <> were digging a pit with their digging tools.

The pit is about 2 meters in diameter.

It took them about three minutes to dig through two floors, or about 15 meters in thickness.

"Master, the hole is open."

"Oh, thank you."

There are no clues or footholds in the pit, but the group has no problems because of the force field generator.

The same is true for the darkness, as there is a night vision mode, so only a little light is enough.

The group slowly descends down the pit and arrives at the fifth basement level.

"...... is very rough."

"It's in disrepair, isn't it?"

Perhaps because it had long been abandoned, or perhaps something had happened to it since then, nothing of note remained here either.

The same was true of the floor below, which was also unventilated, so Jin, who was piloting Jin D, was glad he had not come here himself.

The sixth, seventh, eighth, and ninth basement floors were also in disrepair, and there was nothing to see.

Then, the 10th basement floor.

If this area was also in disrepair, Jin thought that he would leave the control of Jin D to the old man and go to the workshop,

"Oh?　"Oh? Can we expect a little bit more?

He said out loud.

Compared to the previous floors, the floor looked much better.

There was only a thin layer of dust, and the ceiling-mounted <> kept about 70% of its brightness.

"Hmmm ...... but nothing left ......?"

Jin D was disappointed.

He decided to go to the last hope ...... where the <> that extends from ......<> ends.

It is on the easternmost side of this floor.

"I don't think it's ......."

<<> and others, I thought to myself, "Excessive expectations can lead to great disillusionment when they are not met.... Jin, who was controlling Jin D, thought to himself, "Hmmm....

"Hmmm, maybe this is the ...... monitor room."

The room was a room, which indicates that it was a room where the would visit.

And there were various sizes of monitors ...... and perhaps < set into the walls.

But as the old man confirmed with his <, the power in this room was completely stopped and it was not working at all.

"Hmmm ...... I guess it's still not working. ...... but it is... ......"

One thing that has been bothering Jin D so far is that he has been looking at it.

It is .

A base as large as this ruin should surely have a <>.

On the other hand, without a <>, it is impossible to maintain, manage, and operate the facility.

"And there would be no oversight."

Jin thought that since he had looked around with two <> and ten Land troops, there could be no mistake.

"Then that means it's on a floor other than the one we've seen. ......"

It could have been on a floor equivalent to the 3rd or 4th basement, or even lower, which has been buried.

Jin asked Lao-kun to check if there was any further basement with a telescope.

And while the old man was checking, Jin decided to check out this <> a little more.

"...... umm ......"

Through Jin D's vision, Jin felt something strange.

"So,......"

After looking around the room for about 5 minutes, he finally noticed the strange feeling.

"The layout is completely different.

< of the and the were very similar.

However, this room was different in every way, from the placement of the monitors, to the furniture and furnishings, to the angles of the lighting, not to mention the size.

"I wonder if this means that different designers were in charge of the design."

It is strange that only the <> had <> deployed in the first place.

It is known that the two bases had been conducting <> by <> as if it were a game.

It is also known that this <> seems to be a higher level of >.

"Is it possible that this site and the <> together were <> if they were not related to the <>?"

In that case, the difference in power between the two would be very different, and Jin wondered how many times they could continue to play the game of mock battle under such unfair conditions.

"If we can find a management magic brain, maybe we can find the answer to that question," he said.

At that moment.

The old man's voice rang out.
