When they saw the metal water pipe next to the wall, Luke had an idea, he immediately fired a few shots at the ground, and made a few pits, so that everyone put one end of the metal water pipe in the pit, and then put the other end on the metal door, sure enough, this method held the crumbling gate, in order to prevent the two from being not strong enough, everyone stuck several times behind the door before they were ready to rest assured.

The people leaning against the wall looked at the iron door that was constantly being slapped by the zombies, and couldn't help but feel terrified by the extraordinary mobility of this group of zombies. Zhao Zhuoyuan took out his mobile phone from his pocket, looked at the map and said to everyone: "Why are you lucky, if the zombies come out of the safety staircase, it will be over, thanks to ......"

Before the words fell, a one-eyed mad corpse suddenly came out of the floor below the stairwell, everyone's relaxed expressions instantly froze, the zombie looked at the people sitting on the ground, shouted excitedly, used his hands and feet together, and staggered towards everyone, Dai Meng, who was sitting at the staircase, immediately took out a pistol from his waist, screamed and closed his eyes and fired at the mad corpse again and again, just fifteen meters away, but the bullet failed to hit the vital point, but the crazy corpse retreated again and again, thanks to Mo Han, who had been on guard, I saw her holding two guns and firing again and again, and she sent the bullet to the brain of the crazy corpse very handsomely.

Just when everyone thought that there would be no more zombies, a few more appeared on the stairs, and everyone immediately felt that something was wrong, Lao Liu raised his hand and shot all the zombies in the head very neatly and walked downstairs, he said with a serious expression: "Recruits!" I guess there's a door open below! Hurry up and get downstairs! It's only going to get more and more here! With that, he turned on the fire and walked down.

Everyone didn't dare to slack off, immediately followed Lao Liu to the bottom, the two security doors on the second floor of the basement were being hit by the zombies crazy, whenever the impact sounded, everyone would unconsciously nervous, Lao Liu stood in front of the door, stretched out his fingers and knocked the metal door that was constantly hit by the zombies, and suddenly his face changed greatly, Lao Liu took two steps back directly, and pulled the trigger towards the door, he shouted loudly: "This door is not steel, this aluminum alloy door can't hold it!" Shoot the zombies behind the door! Otherwise, you're out of luck! ”

When everyone heard this, they immediately realized the seriousness of the matter, and everyone immediately shot at the metal door, the strong penetration of the 5.8mm bullet pierced the metal door instantly, and the deformed bullet pierced the bloody road in the dry zombie body behind the door, after shooting a magazine bullet in a row, the zombies behind the gate were killed a lot, and the zombies' corpses blocked the zombies behind the door, as expected, the zombies no longer hit the door, this layer is safe, but the next layer is not too optimistic, Although there are not many zombies, they continue to appear on the stairs, and the corpses on the stairs are even piling up more and more, and if they continue like this, it is estimated that the stairs will be blocked.

Everyone reached a consensus very tacitly, and immediately went downstairs while firing together, and after reaching the third floor with difficulty, everyone found that the zombies actually ran out of a hole at the corner of the third and fourth floors, and found the source of the zombies, and everyone immediately used the weapons in their hands to suppress the hole.

Flying bullet casings "clanged" on the ground in the dark corridor, because the guardhouse was well stocked, and the magazines could be discarded as they pleased, and soon the ground was sprinkled with magazines and bullet casings. But there are no fewer zombies, but more and more! As a last resort, everyone took turns firing grenades into the passage, and as time went on, the bullets were about to be half gone, but the door behind them had not yet opened.

Cai Xianzong turned his head with the white smoke of the guard and shouted loudly to Zhao Zhuoyuan and Cai Xianzong, who were tinkering with the access control, "Have you done it!" We can't hold it anymore! Hurry up! ”

After that, he continued to shoot at the zombies, Zhang Zhihong looked desperately at the zombies that kept rushing out of the hole in the wall and shouted helplessly: "Oh Mom! Half a meter thick wall! What the hell did you get it open! ”

Luke, who was changing magazines on the side, smiled wryly and pointed to a corpse in the corner and said, "This kid fired a bazooka in the corridor!" ”

The gunshots in the stairwell crackled non-stop, everyone's ears were buzzing, Cai Xianzong and Zhao Zhuoyuan were under a lot of pressure, the two of them only knew half of what was going on with electrical appliances, and the two of them kept tinkering with the wires on the disassembled access control, but they just couldn't open it.

Seeing this, Lao Liu patted a member of the team waiting for the substitute after hitting the last magazine hanging on his chest, turned around and walked towards the two people who were engaged in the access control, he removed the night vision device on his eyes, turned on the flashlight and shone it on the circuit board, and the dazzling bright light of Zhao Zhuoyuan and Cai Xianzong instantly tingled in their eyes.

Lao Liu pushed away the two and stood in front of the circuit board, he frowned and looked at the complex circuit board on it, and said in a deep voice to the two people next to him: "Help me give me the frame of this input board on it!" I'll try! ”

When Cai Xianzong and Zhao Zhuoyuan heard this, they immediately took the bayonet and pry the frame above, and after removing the frame, Lao Liu gently took off the circuit board on it, and observed it against the light, the gunshots and explosions around him could not affect Lao Liu, who was concentrating, as if everything around him had nothing to do with him.

Luke looked at Lao Liu, who was holding the circuit board motionless, and was very nervous, for fear that Lao Liu would drop the chain at a critical moment, just when everyone was about to be unable to hold on, Lao Liu moved, only to see him holding a bayonet and tinkering with the circuit board very gently.

He said to himself, "I hope you're not as complicated as the Iron Guard." When the resistance was reset, the dismantled access control emitted a slight "ding dong" sound, and the access control operation board was bright, and Zhao Zhuoyuan, who was holding the operation board, immediately operated the door to open the door.

Out of nowhere, the horn suddenly sounded: "Standby power starts!" Please wait! Then in the cheers of everyone, the security door opened, and the zombies rushed out of the breach even more frantically as if they knew that everyone was about to escape, and suddenly the stairwell was in chaos, and the fierce gunfire and the howls of the zombies were mixed together, and together they played a symphony of death.

Because the corpses of the zombies greatly hindered the movement of the zombies behind, everyone entered the location area on the third floor safely.
