After everyone entered the third floor, they immediately covered Qin Baozhu and closed the door, but at the moment when the gate was about to close, the zombies rushed up.

Qin Baozhu and the others took a step back in an instant, and the door that was about to close opened a palm-wide gap again!!

The arms of countless zombies reached through the crack in the door, and when everyone saw this, they immediately went up.

When the crowd was facing the security door, they also used the 95 on their waists to shoot at the door continuously, thanks to the short length of the 95, otherwise it would be troublesome.

As the bullets continued to penetrate the door panel, the power of the zombies became smaller and smaller, and the crowd gradually closed the door.

Seeing that the door was about to close, but the arms of those zombies were stuck, and the most terrible thing was that the security door at this time had been tightly blocked by everyone, and it couldn't be inserted at all, and the bullets in the gun were empty.

Everyone couldn't spare their hands to change the bullets now, and suddenly the scene was deadlocked, and Zhao Zhuoyuan, who was standing at the back of the crowd blocking the door, took out his mobile phone from his pocket with one free hand.

A handful was thrown to Mo Han and Dai Meng at the back of the team, and he shouted loudly: "Password 3333 to find the power supply room!" Open the security barrier door there! It's up to you! ”

Mo Han took the phone, nodded with a serious expression, picked up Dai Meng beside him and ran towards the depths of the corridor.

Mo Han handed the phone to Dai Meng, and said as he ran: "Mengmeng! You show me the way! I'm out of the way! They won't last long! ”

After saying that, the two of them took a long step and ran wildly, and just after Mo Han and Dai Meng disappeared around the corner, Zhao Zhuoyuan suddenly remembered something.

He patted his head and said remorsefully: "! Why am I so forgetful! They won't turn on the backup motor! Hold on! I'm going to find them! ”

After saying that, he chased after him, and before everyone could react, Zhao Zhuoyuan ran out of the range of the night vision device.

Everyone only felt that the zombies seemed to push them backwards and kept sliding.

Luke, who was on top of the door, gasped and shouted, "Brothers, help me hold up for a few seconds!" I'm going down to jam this breach! ”

With that, he crouched down, pressed his right foot against the door, carefully raised his left leg, and just pulled out the spare saber from his boot, only to have the zombie just pound the door.

Because everyone was missing a lot of help, the door opened a two-centimeter gap, and Luke hurriedly stuck his saber in the gap in the lower door.

Sure enough, after jamming a saber, the door did not move, and Tang Ming, who was in the other door, also hurried to jam the saber in, which was able to withstand the door, and the zombie's hand stretched out in the crack of the door kept slapping the heads of everyone behind the door, but no one could spare a hand to teach these damn things a lesson.

Zhao Zhuoyuan chased Mo Han and Dai Meng who were running in the dark, and the three of them ran side by side towards the power supply room, fortunately, most of them were computer rooms, and there was no general office area like the first floor, otherwise it would be really enough to rely on the three of them.

Although one or two zombies often appeared on both sides of the road, they were all shot in the head directly at close range by Mo Han's amazing double guns, and soon the three of them rushed to the gate of the backup power room.

Zhao Zhuoyuan, who was sweating profusely, unlocked the access in a few seconds, and when the door opened the door, something happened that made the three of them desperate.

A piercing siren sounded! In the piercing alarm, the door slowly opened a gap, but there was an excited shout of zombies all around, and then a louder scream, everyone at the top door instantly felt that the night vision device was spent, and there was a wave of nausea in the stomach, it seems that the corpse mother has discovered their location!

They were uncomfortable with Luke facing the door, but Zhao Zhuoyuan at the door of the power supply room was even more miserable, because when they turned around, they found that the door of the safety staircase behind them was open!!

Listening to the increasingly dense footsteps of zombies, the faces of the three people at the door of the power supply room were extremely ugly.

Zhao Zhuoyuan took off the intercom with trembling hands, and said to everyone with a trembling voice: "Brothers! Come to the door of the power room! Or we're doomed! ”

Hearing Zhao Zhuoyuan's desperate shout, everyone was stunned, glanced at each other, and at the same time let go of the door in front of them, turned around and ran towards the power supply room.

The security door that lost its support was opened in an instant, and the zombies behind the door were flashed so violently, all blocked at the gate, and everyone turned around and threw a few grenades and grenades, and the zombies at the door were swept away by the explosive and violent steel ball rain that was blocking the zombie group at the door.

After everyone ran to the door of the power supply room out of breath, they only saw Zhao Zhuoyuan and the three of them looking around with guns on a nervous face, and did not find any zombies around.

Everyone looked at the three people with pale faces and was a little stunned for a while, and before they could ask, everyone heard the piercing zombie howl behind them.

Before he could react, the zombie bit the two team members standing behind, and Lao Liu, who was at the end of the team, immediately reacted very quickly and turned around to kick a zombie who wanted to attack him to the ground, and killed all the zombies that bit the team members with a bayonet, and immediately opened fire to strafe the zombies on the stairs.

Before everyone had time to catch their breath, they plunged into the battle again, and there were less than 400 bullets in their hands, so everyone could only switch to a single-shot mode and fire at these fearless zombies again and again.

The density of fire has dropped by more than a few orders, and the grenades are basically gone, which is really a big problem, but fortunately, the gate has been opened a man-wide position.

Everyone immediately took cover and entered the power supply room, the emergency light in the power supply room was turned on, and the people who went in quickly determined the situation inside, otherwise they would have to take out manpower to guard against unknown dangers, which was really a big trouble.

After entering the power supply room, Zhao Zhuoyuan immediately pounced on the startup panel of the spare motor, and he quickly operated the system above.

With the sound of electricity, a sudden and strong light appeared overhead, and the people and zombies defending in the corridor were temporarily blinded by this sudden light, but it was this crucial few seconds that saved a few people outside.

Because the motor provided abundant electricity, the speed of opening and closing of the metal explosion-proof door nearly 5cm thick increased more than ten times, and those zombies who wanted to squeeze in through the door were instantly crushed into flesh by the strong liquid pressure and broke into two.

The two team members who were attacked by zombies fell to the ground directly after their legs fell to the ground after entering the door, and everyone hurriedly stepped forward to help them to the wall.

Li Mansha put away the automatic rifle that was still smoking, and used her almost unarmed hands to help the injured team member cut the bite place, although the sturdy military uniform did not let the zombies bite off the piece of meat, but their wounds had already flowed out with a trace of yellow-green blood, Li Mansha looked up at everyone regretfully, and Dai Meng was the same.
