"The wall is closing in!"

Jin's doppelganger (Jin D) shouts.

The walls on either side of the room begin to move slowly.

The walls on either side of the room start to move slowly, but the speed is quite slow.

Hmmm, this seems to have something to do with the letters floating on the door.

says in a calm voice. They look like patterns to Jin, but to <> they are letters.

The top one is a number. 188......187... 188......187...186...... countdown.

Perhaps that's the time limit for this wall to crush us.

I concluded after a quick guess based on the speed at which the wall was closing in on us.

Then what do the other letters mean?

"Well, I'll leave that to you. It's a logical question.

What do they say?

<<

"Heh ......"

Jin had heard of this famous problem. However, it was not a jewel but a coin that Jin knew.

"You have a similar way of thinking. ......<<2 times>."

"Mm.

operated what appeared to be a button in the middle of the door and typed <<2>>.

Then the wall stopped moving.

"I guess you were right."

"Yes.

It seems that these quiz-like questions were one of the games for <>.

It seems I have to solve one more question to open it.

"What's the problem?"

<

"What?"

The masters liked to play with these thoughts. ** and ++ are the lapdogs that are not here in Ars.

"No, that's fine, but ......"

Jin had heard a similar <. And he knows the answer. However, he had a slight concern about whether it would be enough.

"Is <> the right thing to do?"

"Yes, that's the right answer. You understood me well.

confirms his answer by typing it into the input area of the door. Then the wall that had been closing in returns to its original position.

One more question.

"Is there more?"

You say that. What is it that belongs to you but is used most by others?

Jin knows this too. He's done it many times with younger children.

A name.

Yes, you're right. is a big deal.

"......"

Jin was not sure whether he should be happy or not.

Regardless of his thoughts, the front door finally opens.

Let's go.

"Okay."

, Rand 11, Jin D, Rand 12, 13, 1 4,15 and left the room in that order.

Beyond that was a similar passage.

"Are the traps gone?"

I can't guarantee that. If it is the same as before, there should be no traps, but I don't know what is happening now. ......

Before he could finish his words, something moving appeared on the other side of the passage.

I was thinking of carving a shifting magic circle, but it seems that time is running out.

"Is it a deformed golem or ......?"

The group is preparing themselves.

No, it is a golem of my type. Perhaps it was sent by the brains of this place.

What exactly is its purpose? Jin and the others braced themselves.

［What is the purpose, intruder?]

To normalize this facility.

stepped forward and answered.

The other golem also has a Mohawk on its head, indicating that it is the same type as the other golem.

［Thank goodness for that.]

What?

An unexpected word came out.

［I know there is something wrong with the central brain. If you can fix it, or rather, if you can fix it for me, I will be happy to help. I am auxiliary golem 066.]

I see, 066, I am . This is my partner, Mr. Koroppo, and the Rand team.

［Okay. Pleasure to meet you.]

Can you take us to the central brain?

［Of course. Follow me.]

The 066 started back the way they came. Jin and the others followed.

"Old man, do you think you can trust him?"

On the island of Horai, Jin, who was wondering about this development, was discussing with the old man.

<

"I guess so. What should we do?"

"I see.

I see.

Okay.

Away from the group that was moving forward, Land 14 remained in place, hidden from view by invisibility.

It seems that the invisibility was not detected.

"Do you want me to engrave it here?"

Land 14's special equipment is a . It can release specific magic without loss of time.

<, it is possible to engrave a magic circle on a metal or other material.

It is in the shape of a large gun, and fires the magic recorded in the cartridge.

<, a will be fired.

<, will be fired.

In this case, <. What it forms is a shifting magic circle.

As expected, it took a few seconds, but we were able to carve a shifting magic circle on the floor.

This will make it easier to send in reinforcements.

How far are we going?

［We're almost there. The destination is beyond that door.]

Okay.

Jin D,<>,land 11,12,13,1 5 were going to the door.
