"Poof."

He jumped straight down, and there was a ten-centimeter-deep pool of water where he landed, but it didn't affect his movements, and a large splash of water fell on the gray-white walls around him.

Strange, what is this place?

The walls on both sides are gray and white, and there are many square dents on them, just like ordinary tiles, but unlike ordinary tiles, with a faint metallic luster.

This corridor-like space is about two meters wide on both sides, and the ceiling at the top is where the subway tunnel collapsed, so a lot of sewage is drained, causing water to accumulate in the area.

And that's not the point, the movement of the two drones has disappeared, and he doesn't know where they went, but his attention is attracted by the lights here.

The whole city has obviously been deserted, and there has been no trace of human beings along the way, but first two flying drones appeared, and then lights were seen here, which shows that the whole city seems to be deserted, and in fact there is still electricity in normal operation.

Doesn't it mean that there are indeed people behind it?

He looked around and looked ahead.

"That's?"

The back of the passage he had fallen from was clogged with crumbling rubble, and at the end of the passage directly in front of it, twenty meters away, there was an obvious circular metal gate with two triangles printed on it overlapping top and bottom to form a strange pattern, like some kind of logo, and it was obvious that it was a passable gate.

Deep in the subway tunnel, there is a gate that you can enter?

Chen Shi was stunned, since he had found a clue here, it was absolutely impossible to give up, he stepped forward, stepped forward, stepped on the splash and walked forward, and within a few steps, he got out of the pool accumulated behind.

"This land...... It's not much like it's made of cement. ”

With the appearance of cement, Chen Shi stepped hard, but he felt a strong shock, and if it was a concrete floor, he should have stepped out of the crack.

Everything here was illustrated, not so simple, he didn't see any schematics or indicators here, only the strange triangular pattern on the gate.

What kind of underground disaster prevention facility is it?

He pondered and came to the gate.

Originally, I was going to think about how to pry the door open after a few clicks, but what I didn't expect was that as soon as Chen Shi came to the door, the round metal door immediately moved, and it swirled open silently, revealing an opening leading to the inside.

“？？？”

Chen Shi was suddenly startled, subconsciously took a step back, and looked around vigilantly.

Why did this door open all of a sudden?

No, it's not that it suddenly opened, but that as soon as he arrived here, he noticed him?

There is nothing strange about this technology, many of the doors of the hotel have adopted this infrared sensing technology, and it will be opened automatically when people come, which is not worth any kind of strangeness.

It's just that in this strange branch of history, any slight change is enough to make people cautious.

The round metal door suddenly opened, and there was no other movement after that, Chen Shi stood in front of the door, and it was rare to hesitate a little.

If he broke into the door, then he would not hesitate, because it was all caused by his actions, but the door opened automatically, so he could not hesitate, because he was afraid of what kind of trap he would have after stepping in.

If his right hand was still in that unstable state, he might not be so hesitant, and the trap wouldn't be able to trap him, but the gamma suit was not omnipotent, if he really had to come to a one-meter-thick iron box to trap him, the gamma suit wouldn't be able to withstand it.

Well, this gate is on top of him, if he doesn't enter, this gate won't close, even if he takes a few steps back, this gate still won't close.

As if to say, you can't get in?

That's really......

He calmed down a bit, and finally stepped inside.

As soon as he entered, he was watching to see if the door behind him would close.

It was really as he expected, as soon as he entered, the door behind him immediately closed, which was obviously different from the auto-sensing door.

It's more like someone is operating behind the scenes.

“……”

Silent, Chen Shi did not rush to violently crack the metal gate behind him, but swept his eyes around first.

Unlike the previous off-white walls, this time the passage is only five meters long, and at the end of it is an open elevator.

"Welcome, unknown intruder."

Chen Shi's glance was not over, and his thoughts and speculations were interrupted by a sudden synthetic electronic sound, which was slightly inclined to a female synthetic electronic sound, without human emotion, but speaking the welcome words of human beings, which was creepy.

Of course, Chen Shi was shocked that this voice came too suddenly, and confirmed his previous bad premonition.

"Who are you?"

Chen Shi immediately asked out loud whether the electronic voice spoke Chinese or Mandarin...... It's not hard to see why, after all, the city has always been the center of politics, and it probably is likely to be the case in this day and age.

"Hello, I'm 'Xihe City' and 'Dijun Underground Broad-spectrum Evolution Laboratory' program-controlled automatic AI, you can call me 'Celestial Phenomenon'."

Underground labs?

Automatic AI?

"Celestial phenomena?"

It's really a big breath, this kind of general term that includes the movement of the sun, moon and stars in ancient times, but it is not generally usable, an AI dares to call itself "celestial phenomenon", or the designer behind it dares to name it "celestial phenomenon", how strong is this self-confidence?

"Are you the AI here? Did you bring me in on purpose? You found out about me a long time ago? ”

Chen Shi asked in a deep voice, with a hint of hostility in his tone.

Such a deliberate act, if you want to say that it is a friendly act, is unlikely to be possible.

"Thank you for participating in this evolutionary experiment, Dijun's underground broad-spectrum evolution laboratory will use an entertaining way to set up corresponding test questions for each tester, and through these questions, the tester's happy emotions will be stimulated to learn ......"

Instead of answering Chen Shi's question, the AI instead talked to himself and said something that made Chen Shi feel inexplicable.

"What are you talking about? I don't understand. ”

Chen Shi frowned.

"Alright, unknown intruder, your test ID number is 1177, please take the test as soon as possible, I will prepare the first test questions for you."

The synthesized electronic voice was still saying words that Chen Shi couldn't understand, and he couldn't help but think, this AI is probably not crazy, right?

How can you say all the crazy words?

Similarly, this also makes Chen Shi's vigilance continue to increase, a crazy AI, and seeing that this AI seems to have a lot of control ability, how can he not be vigilant from the heart.
