Gu Aotian was already slowly walking down the stairs, but Cheng Huan and Cheng Hong hadn't moved yet, and the fat man behind them was in a hurry.

Luo Cheng: "What's the matter?" Two, do you want to go down or not? ”

Cheng Hong looked at the staircase, feeling the gusts of wind coming up from below, and he was scared to death.

"Sister, can you not go down~"

Cheng Huan himself was also very scared, but he didn't show it.

"It's okay, we've come here, let's go down and have a look."

Seeing that Gu Aotian was about to enter the next staircase, Luo Cheng gently pushed Cheng Hong behind his back: "Let's go, don't worry, with the fat man here, those zombies can't get close." ”

Then the three of them hurriedly walked down the stairs, Gu Aotian, who was walking in the front, walked very slowly, very vigilant, he would listen carefully to whether there was any movement below every step he took, and in case of any emergency, he could just pull his legs and run.

But there was no sound other than the faint sound of wind coming from the enclosed staircase.

They walked all the way up the stairs on the second floor to the first floor, where there was a corner at the exit of the stairs on the first floor, and then there was a ramp that led to the underground.

The underground entrance in front of me was very large, more than three meters long, and it looked like it could pass a truck.

Luo Cheng took a flashlight and shone it inside, and it was empty.

"Is this an underground lab?"

Gu Aotian didn't speak, and slowly walked down the slope, the further down he went, the lower the temperature became, making Gu Aotian feel goosebumps all over his body.

The slope is not very long, about six or seven meters, and then what is displayed in front of everyone is a code door similar to the gate of Dazhuang Prison, but the store is closed, and only the red light on the access control system is flashing in the dark, which looks a little infiltrating.

Luo Cheng stood at the door and touched it: "How can this be broken?" It's this kind of door again, and you can't get in without a password. ”

As soon as Luo Cheng finished speaking, suddenly the door behind him slammed for a moment, and then the sound of the hydraulic system sounded, and then the door slowly opened from the middle.

Luo Cheng was frightened by the sudden opening of the door, if the sudden opening of the prison gate was a surprise before, then the opening of this door now is a kind of shock to them.

With the lesson of the previous car, the fat man flashed to the side all of a sudden, and the big knife in his hand was raised, for fear that something would suddenly rush out of it.

As the door slowly opened, a beam of light came through the crack in the door, and as the door slowly spread, until the door was fully opened, there was a light inside, illuminating the basement as if it were day.

Everyone stood at the door and didn't rush in, the door opened, there were no zombies inside, it was surprisingly clean, the facilities inside were all pure white, corridors, walls, lights, etc.

Luo Cheng: "What the hell is this place?" Does the morgue look like this? ”

Gu Aotian: "It doesn't matter where it is, it seems that this is the underground laboratory we are looking for, this door was suddenly opened, obviously the people inside already know that we have found the laboratory, everyone be careful, when we go in, walk together, don't get separated." ”

Then they walked in slowly, and as soon as their front feet entered, the door behind them immediately closed.

This underground laboratory has many individual subrooms, all of which have tempered glass walls, and the facilities in the laboratory are intact, but they didn't find anyone.

All the equipment was still working until they found a dead zombie in a subroom.

The zombie was in an isolated room, with all limbs fixed on a folding bed, with many colorful tubes inserted in the brain, arms, chest cavity and other places, and the brain waves in the EEG machine on the side read in a straight line.

"Wu Chunlong."

Gu Aotian saw that there was an information belt tied to the zombie's arm, on which some personal information such as the zombie's name, blood type, and disease history were written.

Luo Cheng was a little confused: "What's going on?" Could it be that someone is secretly studying zombies here? ”

Gu Aotian: "It's not clear for the time being, looking at it like this, this laboratory should be set up to deal with zombies or zombie viruses, of course, this is just a guess on my part." ”

Chen Huan: "Is it so mysterious to study zombies?" Build the lab under the prison. ”

Gu Aotian looked at the zombie on the bed carefully: "Perhaps, this is just to hide people's eyes or the experimenter has some ulterior motive, okay, let's get out of here first and look elsewhere." ”

After continuing to walk inside, they found that there was another floor below the laboratory, and there was a circular staircase connecting the upper and lower floors, and they continued down the second basement floor.

It was the same airtight door, and as soon as they got to the door, the door opened automatically.

The sub-room on the second basement floor was much less than the first floor, and as soon as the four of them entered, a voice came out of nowhere.

"You're welcome here, my friends."

Gu Aotian and the others suddenly became alert, and the four of them stood back to back and looked around.

"Oh~ my friends, don't be nervous, I don't mean anything."

Luo Cheng: "He ND, why does this voice sound so lame?" ”

Gu Aotian: "Listening to this voice, it should be a foreigner." ”

"Friends, for everyone's safety, now please lay down your weapons and let us have a friendly meeting ceremony. Now please put all the weapons in your hands on the right shelf. ”

Cheng Huan raised his head and glanced at the ceiling, where a camera was pointing at the four of them.

Cheng Huan reminded everyone: "The other party is observing us through the monitor, and he should be able to see our every move." ”

Luo Cheng: "What now?" This turtle grandson can see us, but we can't see him, and we don't know how many people there are on the other side, I said, we came in too recklessly. ”

Gu Aotian: "Don't talk nonsense, what's the use of talking about this now, just adapt to the situation,"

Cheng Hong's voice was slightly nervous: "That... Are we going to lay down our arms? ”

At this time, the voice sounded again: "Friends, my patience is limited, please put down your weapons immediately." ”

Luo Cheng shouted: "Spicy one, there is a kind of you who come out for Lao Tzu, pretend to be a ghost, don't let Lao Tzu catch you, otherwise Lao Tzu will beat you so much that even your mother doesn't know you." ”

After speaking, Luo Cheng took a step back, then accelerated to run, jumped up after three steps, and then slashed directly at the camera on the ceiling in front of him.

In a certain room, the blonde foreigner saw the destruction of the camera and immediately said into a walkie-talkie: "Oh~ This friend, you have violent tendencies, and since you haven't laid down your weapons yet, I have to passively disarm you first." ”

When Gu Aotian heard that his heart was not good, he hurriedly shouted: "Everyone be careful, the other party may be going to do something to us." ”

I saw that two white doors suddenly protruded from the floor in front of and behind where they were, and then trapped four people in the aisle at once.

A white smoke then emanates from a vent above the ceiling.
