Chen Shi is not an uninformed bun, he has seen the gate of the Wudaogou underground nuclear bunker, as a gate that can prevent nuclear explosion, the volume and thickness are really amazing.

And the gate at the foot of this Black Mountain has also exceeded the scale of the gate of the nuclear bunker, no less than the height and width of the Arc de Triomphe, the thickness is unknown, and it will not be very thin if you think about it.

Montenegro, as the name suggests, is really black as a whole, especially this gate, the incomparably hard rock constitutes a black stone wall, its pure black like lacquer, glowing with black light, the stone feels hard and greasy, with a simple and unpretentious, peaceful and natural feeling.

At a glance, you can notice the difference from the surrounding stone walls.

"You want to get in from here?"

Chen Shidu's neck hurt before he leveled his gaze and waited for 1214-B01 to open the gate like he had done last time.

To his surprise, 1214-B01 fumbled back and forth on the black stone wall, and instead of using the previous card, activated some kind of switch, and with a "boom" sound, a small door slid open from left to right, revealing a deep dark passageway.

"Huh?"

Chen Shi was stunned and speechless, daring to open the entire gate.

Without waiting for Chen Shi to speak, 1214-B01 had already walked in directly by himself, Chen Shi did not hesitate any longer, and his eyes motioned for Xingdian to follow.

In the quiet passage, it was difficult to hear any sound, only the movement of everyone walking echoed in the ears, and after Chen Shi and the three of them entered, Bingyu hurriedly followed, and just ten seconds after it entered, the small door that slid open returned to its original position again, as if nothing had happened.

There were no lighting measures, and there were no lighting equipment, only Chen Shi was the only one in the group who was not affected much, and the night vision mode provided by the gamma suit was enough for him to see his surroundings clearly. And 1214-B01, which is at the forefront, is obviously quite familiar with this place, and can walk down skillfully without seeing this place clearly.

The passage was very long, about 100 meters long, and when they stepped into a hall, suddenly, the incandescent light illuminated the entire hall, and in front of Chen Shi, the elevator doors of Arabic numerals 1 to 19 were neatly arranged.

"This is an elevator?"

The elevator is still very easy to identify, especially in front of each elevator door, there is a button with an upward arrow, which allows Chen Shi to confirm that this is probably an elevator.

However, isn't it a bit too much for a full nineteen elevators?

While he was wondering, 1214-B01 walked briskly forward, stopped in front of the fifteenth elevator door, and reached out to press the button of the upper arrow.

“……”

Nothing happened?

After waiting quietly for a while, Chen Shi stepped forward and stared at 1214-B01, "What's the matter?" ”

"No, I don't know."

1214-B01 shakes his big furry ears in confusion.

"Well, maybe it's out of power...... Well, could it be broken? ”

Chen Shi saw that the lights around him were on, and immediately changed his words.

"Will the rest of the elevators work?"

Chen Shi casually pressed the button next to him, that is, the button of the fourteenth elevator.

"Hmm, still no response?"

He walked over to the thirteenth elevator door and pressed the button again.

"Well, still no...... Hey? ”

Chen Shi, who was about to continue walking, stopped, and was surprised to see the elevator door sliding open silently.

"This elevator is good?"

Chen Shi thought about it, and did not rush in, but went to press the buttons in front of each elevator door one by one, after his test, there were a total of nineteen elevators, seven of the good elevators, and the rest were damaged and could not be used.

Is this number small?

Not only are there a lot, but there are too many.

1214-B01 only knows how to enter from elevator number fifteen, and doesn't know anything about the rest of the elevators, if these elevators are all to the same place, what if not?

"B01, do you think these elevators go to the same place?"

Chen Shi asked thoughtfully.

1214-B01's big ears are folded, indicating that he does not know.

"Well, maybe there are so many elevators because there are too many people......"

Chen Shi also knew that his guess was not very tenable, he came in from the passage just now, turned around to see, there was only this one passage, obviously the real gate did not lead to here, so there was no need for so many elevators.

In contemplation, Chen Shi glanced around, there was so much dust accumulated around, it should be that no one had been here for a long time, not that no one had come for so long and there was still electricity, but this was further verifying a conjecture that no matter who the builder was, the passage to the upper and lower realms had been untouched for a long time.

Why doesn't anyone come and go?

Two possibilities, one is that the builders behind the scenes have long since died. The second possibility is that for some reason, the builders behind the scenes evacuated the place, causing the place to be abandoned.

Chen Shi was still thinking here, Xingdian and Bingyu over there looked around in confusion, full of puzzlement about this place, they didn't know where Chen Shi had taken them, but soon, they had a doubt in their hearts, how did this place look like ...... Ancient ruins?

"Hey......"

Chen Shi couldn't think of a reason, so he decided to choose one of the elevators that could work normally, and that was ...... Number six, he loves this lucky number.

"B01, let's go."

Waving, Chen Shi motioned for 1214-B01 to follow.

Walking into this elevator that was still in good condition, 1214-B01 of course followed, including Xingdian, and did not hesitate, even Bingyu in the distance only hesitated for less than a moment this time, for fear that Chen Shi would leave it here alone, and ran in quickly.

In the elevator, there is no common one, two, three, four in the order of the floor button, only a round button exists, Chen Shi has no choice but to choose this button to press.

As soon as the button was pressed, the lights in the elevator suddenly lit up, and the miserable white light illuminated the small space in the elevator, and everyone's faces were pale.

The elevator door slowly closed the wall, with a vibration, the elevator moved quickly, after a slight sense of weightlessness, then turned stable, four people stood in the elevator and waited silently, estimated that it was about five or six minutes, and the elevator stopped suddenly.

"Arrived?"

Chen Shi raised his vigilance and prepared for battle, no one in this place knew what was there, if he opened the elevator door, it would be a group of xenomorph monsters...... That's going to be funny, it's going to be embarrassing.

However, it did not usher in the imaginary monster.

Because, this broken door has never been opened...... Since he stopped, he has been quietly closed and has not moved, allowing the emotions prepared by Chen Shi to brew in vain.

"What's going on? Why didn't this door respond? ”

Chen Shi was extremely puzzled, he wondered, and the rest of the people were even more puzzled, looking at each other and not knowing what to do.
