An underground city where golems and automata come and go.

<

（I don't hear any audio conversation.)

（I thought they were communicating with each other, but they are not.)

(In other words, the golem and automata here may just be repeating the same actions.

（Why on earth would they do that?)

（That remains to be seen.)

As far as I have observed, the golem and the automata going through the town just keep moving without any purpose.

As a proof of this, when we targeted one golem and one automata and followed their movements, they circled the town and returned to their original places in about one hour.

(A crowd for show only, or ......)

Even if that is the case, I don't know what the purpose is.

(It is unlikely that we will find out anything more without further investigation.)

Shinobu I said so and decided to move on to the next stage.

The destination is the well-known tower in the center of the town.

（This is precisely the time to be cautious.)

（Understood.)

< and .

The path of the golem and automata is fixed, so as long as they stay close to the building, they do not worry about being kicked off or tripped over.

They move at a speed of about one kilometer per hour.

We made it to the bottom of the tower in about an hour without any trouble.

（Now, it was time to go in.)

(Now, it's time to go in...) From what I observed, it seems that there is an automaton that comes in and out of the tower once every two hours.

I will jump into the tower at that time.

It will be about an hour and a half until then.

(I have to make a tentative call in two hours. ) So, I leave the text of the message with Corporal Shinobu and Riku. I'll ask you both to stay here and provide regular contact and backup.)

（Understood.)

(Our numbers are dwindling, but we are probably close to where we want to go.)

(The number of people is getting smaller, but we are probably close to where we want to go.

An hour and a half later, an automata arrived as expected.

At about the same time, the entrance to the tower opens.

An automaton comes out from inside. Then, the automaton that came in place of the first one goes inside.

The interval is about five seconds. <

（They have successfully infiltrated the tower.)

The interior of the tower is almost the same as that of the Somark Ruins.

Shinobi I, II, III, and IV spent about five minutes observing the first floor.

（It's definitely the same building as the tower we know.)

（Yes. That means, if there is a magic brain, it must be in the basement.)

（Are there any golems or automata that go to and from the basement?

(Are there any golems or automata that go to and from the basement?)

They waited again and continued to observe.

* * * * * * * * * * *

Half an hour later, Shinobi-ichi and four others infiltrated the tower.

When it was time for the scheduled communication, Shinobi Corporal sent the text that Ichi had entrusted to him.

In Horai Island, the old man who received the message immediately reported to Jin and the others.

"Hmmm, I guess there are no humans here after all."

"Then, we are waiting for the report from the Shinobi Unit that has infiltrated the tower?"

"I can't wait."

* * * *

At the same time, the Shinobi Unit, which was observing the situation inside the tower, came to a conclusion.

(Apparently, there are no golems or automata traveling to and from the basement.

(...... What do we do?　We know the location and structure of the elevator. But we can't force open the door or move the elevator (......).

(You never know what's going to happen. ............)

Shinobu I thought about it and came up with an idea.

（This is where the fourth of the seven tools comes in.)

The fourth tool is the .

Since it is called "simple", it can mimic only the magic patterns of Jin, Marikka, and <> Thales, not just anyone's. Of course, all three of them can be found at .

Of course, all three of them ...... made Jin by themselves, but I have told Marikka and <> Turles about this kind of use, and they have given me permission to do so.

It is a kind of duplicating fingerprints, so to speak.

(In this case, I will use 's fingerprints.)

I set the timer. I set the timer next to the entrance door.

I set the timer to go off after they leave, so that I can observe the reactions inside the tower.

(It will be activated in 3 seconds. ......2......1......0!)

Once the <> was activated, dramatic changes took place.

First, the golems and automata that had been moving around in the tower stopped at once.

Next, all the functions in the tower stopped.

(Did something ...... happen?)

<.

The tower standing in the center of the city, beneath the tower.

There is the < there.

Unlike the other cities that Jin and his team have discovered so far, the magic brain here is working properly.

The creator of this magical brain is, of course, one of the of the .

He was a person who could be called even more eccentric than the other members of the .

He is the one who built the same size, the same scale, and the same specification of magical brain in order to experiment for <>.

And the magical brain built in the basement of this city is also exactly the same in terms of specifications.

In other words, the four magical brains are brothers or sisters. No, the city itself is a .

In other words, their databanks and information contents are completely compatible with each other.

Not only that, the elements that make up the cities (...... structure, composition, materials, etc.) are the same and can be used in the same way.

Therefore, after the other three cities stopped functioning, they sent a recovery team to utilize the parts that could be used.

The last order left behind by the masters is the one that the observes.

These were the two.

For this reason, <> was managing the city day and night, using golems and automata to maintain its functionality.

<, as interpreted by the magical brain, included the and .

And now, through the magic sensor, there was a very worrisome response: .......
