Bai Qi climbed down the fire pipe first, and Huang Mao grabbed the fire pipe, ready to pull him back at any time.

Bai Qi walked downstairs to the window, and when he looked around, the office was in a mess, but there was no trace of the infected person.

After climbing a few times, Bai Qi has gradually adapted to this kind of high altitude, and is not so afraid, in fact, after overcoming his fear, this kind of climbing is not difficult at all for Bai Qi, whose strength is three times that of ordinary people.

He stretched out his foot and kicked the window frame, and the whole person swung outward, and when he swung back, one hand grabbed the window frame, and both feet landed on the window sill.

Jumping lightly from the windowsill, Bai Qi quickly took off the shield behind his back, lifted it in his left hand, and pulled out the short knife tied to his calf with his right hand, and gently came to the door of the office, and glanced out.

The entire corridor was also silent, and it seemed that all the infected had left the place.

Bai Qi returned to the windowsill and was about to call Huang Mao to come down, but he didn't expect Huang Mao to slip down without waiting for his notice, Bai Qi couldn't help but glared at him fiercely.

For the sky, Huang Mao did not have the same fear as Bai Qi, he also learned from Bai Qi to step on the window frame, and swayed into the window very dexterously.

Bai Qi waved his hand, held the shield, and walked out of the office lightly, Huang Mao took off his rifle from behind his back and followed behind Bai Qi.

The two of them walked through the hallway to the door leading to the safety staircase, which had become a scene of Shura's hell.

The two doors pinned by the fire axe had collapsed entirely, several desks blocking the doors had been pushed to the ground, gnawed white bones were thrown everywhere, and scarlet blood was everywhere on the floor and walls.

There was no sign of an infected person near the gate.

Bai Qi cautiously stepped over the overturned desk and the toppled door, passed through the doorway, and came to the safe passage.

Just as he stepped through the door, an infected man climbed up from downstairs with his hands and feet, and they collided head-on.

Bumping into an infected, Bai Qi was not afraid, and he was about to take action, when he heard a low howl from the stairs above.

Bai Qi turned his head, only to find that there was also an infected person staring at him on the stairs leading to the top of the building, squatting down and trying to pounce.

Bai Qi was taken aback, and hurriedly shouted to Huang Mao behind him: "Stand back, be careful!" At the same time, he took a step back and blocked the door to the hallway with his body.

The two infected, one up and down, pounced on Bai Qi almost at the same time.

Of course, the two infected Bai Qi couldn't stop it, but he had nothing to fear.

If it was an ordinary person, he would definitely be flustered when he encountered such an uncoping situation, but Bai Qi was at this time, and his brain turned faster than usual.

I saw him lift the shield with his left hand to block his head and face, and with his right hand he threw away the short knife, stretched his hand to his waist, and touched the ** he had just gotten, and at the same time bent over and bent his legs, separated his feet back and forth, and nailed himself to the ground.

"Bump!" With a muffled sound, the two infected people first bumped into each other, and then hit Bai Qi's body, and the huge force instantly knocked him to the ground, and the two infected people pressed on his body side by side.

At this time, Bai Qi had already pulled out **, he held a shield in one hand to protect his head and face, and without looking, he shot at the two infected people on his body.

If it was two people who knocked down Bai Qi, he would be able to shoot through both of them with this random shot, but the musculoskeletal strength of this infected person was extremely tough, and he fired seven shots in a row, but all of them shot into the body of one of the infected people on the right side, and the one on the left was unscathed.

However, at this time, Huang Mao's gun also rang out, and in order to fear that the bullet would penetrate the infected person and injure Bai Qi, Huang Mao took a crouching position to shoot, and a shot hit the forehead of the infected person on the left, lifting its skull.

Bai Qi pushed away the two infected people who were pressing on his body, turned over and stood up, staring at the stairs outside the gate, while quickly inserting the ** who had just saved his life back into his belt, and grabbed the short knife on the ground and stepped back.

Bai Qi had just retreated three meters from the gate when an infected person rushed out of the door.

Bai Qi immediately stopped, knelt on one knee, raised his shield and shouted, "Shoot!" ”

The AR15 rifle in Huang Mao's hand rang out, hitting the infected man on the eyebrows with precision, causing it to fall to the ground.

However, the howl outside the gate sounded again, and Bai Qi and Huang Mao could only retreat again and again.

The next moment, two more infected people rushed in from outside the gate, and Bai Qi fell to one knee again, giving up the shooting vision to Huang Mao behind him.

Huang Mao's first shot hit the cheek of the infected person in front of him, but the second shot flew past the ear of the infected person in the back.

Bai Qi shouted: "Stop!" He didn't care whether the yellow hair behind him understood or not, so he rushed up, pressed the shield with his shoulder, and collided with the infected person behind him.

This infected person should have been a white man before his death, tall, Bai Qi was less than one meter seven tall, coupled with the deliberate cat waist, the shield was fiercely placed in the abdomen of the infected person, making it bend down involuntarily, Bai Qi straightened his waist and flipped it to the ground.

Huang Mao took the opportunity to step forward and fired two shots in succession, killing it.

Shooting the infected, Bai Qi waved his hand to Huang Mao, and the two stepped back again, Bai Qi said on the side of his legs: "Retreat to the door of the office on the roof, if you can't do it, retreat to the roof." ”

Huang Mao retreated to the door of the second office, raised his gun and stopped, Bai Qi half-knelt down three meters in front of him, and the two stared closely at the door leading to the safety staircase.

However, this time the two waited for a long time, and no infected person appeared.

Bai Qi waved his hand, and the two walked towards the gate again.

Bai Qi cautiously walked through the door leading to the safety staircase again, but this time he was not attacked.

He raised his shield and stood guard in front of the door, and said to Huang Mao without looking back: "Find the fire axe from the other door." ”

Huang Mao hung the rifle around his neck, separated the two fallen gates, drew the axe from underneath, and said, "Got it." ”

Bai Qi beckoned and walked up the stairs.

Leaning against the wall, slowly walking up the stairs, the iron door leading to the top of the building was stacked with the corpses of more than a dozen infected people, and one corpse was dragged to the corner of the stairs, out of sight of the shooting hole on the iron door on the roof.

The corpse's most muscular thigh had been gnawed into a large hole, leaking out the white bones inside.

It seems that this should be the good thing done by the infected who pounced on Bai Qi from the stairs above just now.

In order to avoid accidental injury from the people guarding behind the iron gate, Bai Qi shouted softly: "We are here, don't shoot." ”

After hearing Qin Qing's answer behind the iron gate, Bai Qi waved his hand to Huang Mao and asked him to open the door.

After letting Huang Mao go, Bai Qi stood at the corner of the stairs.

With two loud bangs, Huang Mao cut the door lock, and the iron door finally opened.

According to what everyone had discussed a long time ago, Qin Qing and the others immediately dragged the corpses of the infected people piled up at the iron gate.

In the end, Bai Qi dragged the infected person who had been eaten on his thigh back to the roof of the building.

Huang Mao closed the iron door and used the fire axe to break through the handle and pinned it.

After that, things were simple, and everyone was already familiar with it, and everyone threw the body off the tall building, still in front of the building, facing the square of the city.

Soon, the corpses attracted several infected individuals.

They quickly fell under the snatch of the yellow fur
