"Well, let's check inside."

Jin said, "It would be great if we could find one or two useful documents," and started to examine them first.

The floor was littered with pieces of something, so much so that there was no place to step. It seemed to be a broken shelf board.

"What the hell happened here? ......"

Zion mutters in disgust.

"Really. Is it like this in the other rooms?"

Goose responds to Maricka's words. He runs out of the archive and peeks into the room on the other side,

"Yeah, this one too ......!"

he shouted.

I checked the rooms on both sides of the room, which had also been vandalized to varying degrees.

"What does this mean?"

"......Well, the only thing I can think of is that ...... for example, they had to get rid of this place in a hurry, so they hurriedly packed up everything?"

Guth looks as if he's biting his tongue. No wonder. I came here with great enthusiasm, expecting to find some valuable materials, only to find them in this mess.

"Or maybe some thieves or something came in and trashed the place.

This may be closer to the case with this mess, Saki thinks.

In any case, it was disappointing that none of the materials we wanted to see could be found. Everyone's shoulders slumped.

"Hey, girl, do you have any magic brain in here?

Then Hannah opened her mouth.

"It would be nice to have a magic brain or ......."

< have a magic brain to manage them.

However, this remains was limited to the lowest level of mana.

So, it is highly likely that it is dormant even if it exists.

"Hmmm...there must surely be some, given the lifestyle of the <>."

Jin agreed with this idea.

"Is it possible that they stopped maintaining this site ...... because there is no longer a need to maintain the facility?"

"But the air conditioning and minimal light are still maintained, right?"

Hannah countered with the word <.

"It is possible that the roles are shared. Or maybe they are just maintaining the environment independently."

Jin said, "Anyway, since we've come all this way, let's look for them," to which everyone agreed, not wanting to waste time.

"Then, this level or one more level down is probably the best place for us to look.

"Well, that's true. ......I've already searched all of this level, so maybe it's down there?"

"Yes, that's right. ...... Maricka, can you check?

"I'll try."

Marikka, who had heard Zion's words, put her right hand on the floor and used her <> magic.

"...... Oh, there seems to be a cavity."

With that Marikka moved about 10 meters and used the sonar spell again.

Then she moves about 3 meters and uses the sonar again.

Jin watches silently. Marikka is doing what he was going to do.

Even if it was a little poor, it was because it was a sign of Marikka's growth.

"There it is!"

After several moves and attempts, Marikka found a large cavity downstairs.

"There it is. I knew it. ......."

Jin also tried using the sonar at the location. Indeed, there was a large cavity below the floor.

"Yeah, it sure is. Marikka, you have improved your skills.

Marikka is also Jin's student. Jin was pleased with her progress as if it were his own.

"Oh, thank you very much!

Marikka blushed but was happy when Jin praised her. Theon patted her on the shoulder, saying, "Good for you, too.

"Now then, what should we do? "Well, what do we do now, find a staircase or something to go downstairs, or make a hole in the floor?

"Maybe there's a maintenance staircase," says Hannah.

Hannah said.

"Yeah, ......."

Now that the time had come, there was no room for hesitation. Jin contacted the old man and asked him to search for the staircase with a "peepers".

A minute later, a report came through Reiko.

"Father, I understand. It's ...... here."

Reiko led the group to the place, because she gave the actual point, not a verbal description.

"This way."

It was a place that seemed to be located at the opposite side of the staircase that led down to this level.

Reiko put her hand on the wall, and the part of the wall popped out and became a lever to open and close the door.

Reiko lightly pulled the lever.

With a faint creaking sound, the door opened and the stairs to the bottom appeared.

"Let's go."

The old man made sure that there was no danger, so Reiko led the group willingly.

Reiko led the group down the stairs in the order of Jin, Hannah, Goose, Saki, Zion, Marikka, and Nurse Alpha.

This is a spiral staircase, and after descending about 15 meters, you will reach the level you are aiming for.

There was no door, and a dimly lit passageway opened up.

"It's just up ahead."

The group followed Reiko who walked without hesitation.

After walking about 20 meters through the narrow passageway, which was barely wide enough for one person, they came to a space about the size of a school classroom.

There was only a depression on the floor about 2 meters in diameter and 10 centimeters deep. The view was aptly described as empty.

"There's nothing here. ......"

Saki's shoulders slumped in disappointment.

"Perhaps this depression is where the magic brain used to be?

Jin mentioned a possibility.

"If so, does that mean it's been removed?"

Goose looked disappointed.

"I wonder why it's like this?"

Hannah also tilted her head.

And Zion and Marikka were silent with a slight frown on their faces.

"Well, what should we do ......?"

Jin thinks for a moment, but there seems to be nothing more he can do.

"Oh, and I'll ask < about this place!

Marikka said.

<> is, coincidentally enough, the magical brain that controls , the facility of the that Marikka inherited.

If has been in operation since the distant past, it might be able to explain this situation.

"Okay, let's go back."

Yes.

"Right."

Everyone agreed with Jin's words.

"It's a pity that we lost the last part of the meeting," said Zion a little apologetically.

Zion said a little apologetically. It's not like a rat in a mine, but it's hard to relax when you think you've made a great discovery, only to find out that it's an abandoned ruin.

No, this happens sometimes.

Jin consoled Zion,

"If we can learn more about how it happened, we may be able to understand more about the than ever before.

Guth also expressed his opinion.

"That's right. In a sense, we can say that this is a new discovery.

Hannah also said in a cheerful voice.
