Lu Yan is in the corridor of Unit 5, and the security room where the monitoring system is located and Liang Chen are in Unit 2, so she must find a way to go back.

There are several ways to cross the unit, one is from the outside, there is a unit door leading to each unit outside the building, the second is from the roof, there is a stairwell of each unit on the roof, the third is from the hall on the first floor, and there are elevators and stairwells of each unit in the corridor behind the hall, which is the key protection area of the police, and now it is also the place where the most police corpses are located; the fourth is from the underground parking lot, whether it is the first or second floor, there are elevators and stairs, and the stairwell is generally locked, but no one will care if it is pried open today.

Walking from the top of the building is the safest, Joel is on the seventeenth floor, far from the roof, the police on the first floor have been cleaned up again, the other party has no need to go to the roof, and the building has a total of thirty-two floors, it takes a long time to go up and down, it takes a lot of physical strength, and just going down the stairs can shake his legs.

The first floor and the basement floor are the most dangerous, Lu Yan doesn't know the situation in those two places, but since even the people who escaped into the stairwell have been killed, then the hall on the first floor should have been a dead place, and if you go, it will become a part of the "death".

It is not safe to jump outside from the second floor and enter through a separate unit door, there are people in the security room, surveillance cameras are all over the public places of the building, only the corridor that is basically unused is not installed, and it will be found immediately when you enter through the unit door.

Although there are many paths, there is only one choice, that is, the second basement floor, because the occupancy rate is not high, the parking lot on the second basement is not open for use, and it is dark below, from where it is feasible to return to the second unit.

Lu Yan walked down in fear, strictly speaking, she was still in the war zone, when she went down to the floor, if someone suddenly walked into the stairwell and didn't even have a place to hide, she took off her low heels, barefoot, stopped to listen to the movement when she walked to the corner of the stairs, and then rushed down by dodging bullets.

When she got to the first floor, she was the most nervous, because there was still a corpse lying there, blocking the door, and if someone was at the door, she could see it directly, she walked lightly to the door, approached the crack in the door and took a look, and saw several corpses in a pool of blood, without anything moving, and rushed down with her shoes, this time rushing to the second floor of the basement in one breath.

The door was locked, it was the right door to open, Lu Yan put away the pistol, pulled the doorknob, pushed and pulled hard, using the principle of resonance, the push and pull amplitude became larger and larger, and finally I didn't know what was broken, "pop", the voice-activated light turned on, and the door opened violently.

The light could only illuminate a small area of the doorway, and beyond that it was extremely dark, there was no sound, not even the wind could blow into the underground space, and the cold air came to the face, with the smell of rotten dust, like an ancient beast breathing in the ice age.

Lu Yan shuddered, illuminated the wall with the light of the mobile phone screen, and groped her way forward, the building structure here is no different from the basement floor, so she will not get lost.

The new building, no garbage, but clean, no rats scurrying around, but there are some bugs on the wall, palm-sized spiders have seen some, and there are also a lot of insect corpses in the corner, which makes her nauseous, fortunately, the road is not far, she quickly turned into the depression of the second unit, and a few steps further, the light of the mobile phone screen reached the door of the second unit.

Lu Yan stopped, held her breath, her muscles tightened with tension, and she stood in place.

The door was open.

The creepy chuckle of "hee-hee-hee......-hee" resounded behind him, echoing in this huge space, and it was impossible to distinguish the specific direction.

Lu Yan turned around violently, quickly took out a pistol and put it on his left arm facing forward, holding the mobile phone in his left hand, and the screen could illuminate a small area in front of him.

"Don't be so impulsive, I just want to play with you, anyway, there's nothing to do now, let's play blind fishing, the person who is caught will be hanged, hehehehe......" The voice continued to float.

Lu Jing stepped back, she could hear that this voice was the one on the phone before, the other party came out of the security room, guessed that she would go here, so she waited here in advance, waited in the dark, watching her every move.

"Retreat to the door, close it, and bolt the handrail of the door, and you will avoid the man coming after you. She thought about her next move as she stepped back, and though she was terrified, reason did not abandon her.

As if he had guessed her thoughts, the man in the darkness smiled and said, "Do you think I would come to this place alone at the risk of being locked out? ”

Lu Yan stopped her steps, biting her lip and listening to the movement behind her, she couldn't hear anything, but she always felt that there was a tall person standing behind her, very close, looking down at herself.

Sometimes I feel this way when I sit at home and play on the computer.

She resisted the urge to turn around, closed her right eye, fired two shots, and then quickly closed her left eye and opened her right eye again.

The firelight illuminates a large area, and the image will remain in one's mind, so that you can recall all the details carefully, and the purpose of opening and closing your eyes is to keep your vision dark, so that both eyes will not be blinded by the firelight.

"Clever, I'm getting more and more interested in you, driving a man who can always keep his sanity to the brink of collapse and madness, but it's funny, hee-hee......" The man's voice sounded again, still difficult to distinguish between distance and location.

Lu Yan shot first to illuminate the distance with firelight, second to deter the other party, and third to light the voice-activated light, the light is shining from the inside, if there is someone behind her, there will definitely be a shadow in front of her, she didn't see the shadow, which means that there is no one behind her at all.

That's two shots in one fell swoop.

She continued to step back, step by step into the unit door.

"Continue, continue, you're about to see it, keep ......retreating," the man's voice was visibly excited, as if Lu Yan was retreating into his trap.

Lu Yan didn't believe that person's words now, but she knew that she couldn't be careless, that guy might just let her look back in order to make her not believe his words, and his words were very clever, first saying that he didn't come alone, and then let her look back, and didn't say that there was someone standing behind her, obviously misleading her, and the room wanted her to think wildly.

Stopping, Lu Yan waited until the voice-activated light went out, flicked her tongue again, and turned the light on again, then raised the gun with her right hand and pointed outside, closed the door on one side with her left hand, and then pulled the handle of the door on the other side.

But just then, she heard footsteps behind her.

"It's counted, but don't hurt her, hee ......" I don't know if it's because the door is closed, or if it's because of a narrow space, the other party's voice has become significantly quieter.
