Opening the door of the fire escape, Chen Bo and everyone were found by the corpses outside as soon as they emerged.

The group of corpses in the middle of the hall fell down, and the zombies wriggling on it merged into the sea of corpses below, and they all rushed towards the fire escape like a tide.

Chen Bo roared and threw two grenades at the group of corpses that rushed over. The explosion sounded, and the place where the grenade landed suddenly blew up a space, but it was immediately filled by zombies rushing from behind.

The grenades thrown into the corpses were like small stones thrown into a pond, and had no other purpose than the flash of fire that bloomed in the moment. More than a thousand zombies were concentrated in the hall on the first floor, and their movements could no longer be stopped by a few grenades.

The bullets kept pouring forward, and at the front of the corpse group, the zombies fell in pieces like cutting wheat, and more zombies rushed up from behind, stepping on their bodies and rushing towards the fire escape.

"Kill," Chen Bo's hand holding the gun burst out, "Brothers, throw out all the grenades, kill one without losing money, and kill ten blood to earn." ”

One grenade after another was thrown, followed by a series of explosions from the crowd. The explosion effect of a dozen grenades gathered together was indeed much better than that of one or two thrown alone, and the momentum of the corpse group slowed down significantly in the explosion just now, many zombies were swept to the ground by the air wave, and more zombies were in the explosion and their limbs were incomplete.

Even if the zombies that fell to the ground did not die, they indirectly hindered the footsteps of the zombies that followed behind. Taking advantage of this opportunity, the soldiers harvested the lives of many zombies, and their feet were scattered with bullet casings that had withdrawn from their guns, and these shells fell to the ground and made a series of "ding-dong" sounds, intertwined with the sound of tongues of fire spewing at the muzzle of the guns, constantly echoing in the passage.

With a "click", a soldier's gun suddenly went silent.

"Team leader, no bullets!" The blood in the soldier's eyes gradually faded, and he looked at Chen Bo, not knowing what to do next.

Chen Bo was stunned for a moment, and finally calmed down from the continuous shooting. They had already consumed a lot of ammunition on the escalator before, and although they had all passed it once, there was not much ammunition left. The grenades had already been used up in the wave just now, and everyone would definitely run out of bullets like this warrior.

"Withdraw, we'll go back." Chen Bo did not hesitate, and immediately beckoned the soldiers to retreat into the fire escape behind him. The wave of their breakthrough just now had already failed, and it had not even been ten minutes since they had rushed out at the beginning to now they had retreated, and they had not rushed out of the area near the entrance of the passage.

"." After failing to break through and being blocked back, Chen Bo's heart was very depressed, and after retreating into the fire escape, they continued to run towards it non-stop, and the door behind them had been broken open by the corpses, and many zombies poured into the passage and chased upstairs.

During the retreat, one of the fighters turned around and began shooting at the zombies behind him. Chen Bo heard the gunshots behind him and looked back, and suddenly felt indescribably sad in his heart.

"Dayong!" Chen Bo yelled at him, "Let's go." ”

"Team leader, you withdraw, I'll cut off the brothers," Da Yongtou said without replying, the gun in his hand continued to pour ammunition at the zombies chasing up, "Remember to help me burn incense for my grandfather, and tell him that his grandson has never been cowardly today as he was on the battlefield in Funan." ”

"I'll keep ...... too," Wang Jinxi was about to turn around and stay together, but he was grabbed by Chen Bo, and ran upstairs with a gun.

The corpses rushed up the stairs, and it was difficult for Dayong to block the entire corridor with the frontal fire, and the bullet casings flew in front of his eyes, and when the last bullet in the chamber flew out, the zombies in front of him had already pounced in front of him.

The screams came from the corridor, and the soldiers had already run up to the second floor, and they continued to rush up to the third floor without stopping.

"If you all confess here, Dayong will die in vain," Chen Bo said with red eyes, "Who will burn incense for his grandfather then?" ”

The others beside him were silent, Wang Jinxi clenched his teeth, and tears had already flowed.

More than a dozen zombies pounced on Dayong's body, and after a moment of effort, he was silent, and the zombies around him couldn't squeeze in, so he had to continue to chase other targets upstairs. However, Dayong's corpse remained there, and the zombies surrounding him blocked the tide of corpses behind him for a moment, until they were squeezed to the ground, and their bodies were trampled by the crowd of corpses that came from behind.

"If only there were grenades," Chen Bo looked down into the gap between the railings of the staircase, a narrow position in the corridor that maximized the damage. The zombies below chased after them, and the footsteps in the corridor were thunderous for a while.

"Don't look back, keep running." Chen Bo shouted loudly.

The bodies of those trapped in the hallway were still on the stairs. A soldier accidentally stepped on the bones in the remains of the corpse, and a "click" sound came from under his feet, and his ankle was cut by the sharp place where the bone was broken.

Feeling the pain coming from under his feet, the warrior looked down, but his body accidentally slipped and fell to the ground. The companion next to him reached out and pulled him up, and in the gap between the delays, the speed of the two slowed down suddenly, and they were left at the back of the line.

The corpses behind them were very fast, and the smell of fresh blood in the air made them even more restless, and the low roar kept sounding in the corridor, adding another layer of shadow to the hearts of the retreating people.

The warrior with an ankle wound was the target of the Losers' scramble to pounce on him, and he was caught in the heel by the nearest zombie who was chasing him.

The warrior's foot was pulled from behind by the zombies, and his body fell to the front, and the whole person was dragged into the corpse. Fang Cai pulled his companion to try to catch him, but his hand reached a little late and was empty.

The rushing corpses had already pounced in front of them, they were not affected by the light and air in the corridor, and the living and blood stimulated their nerves like stimulants, causing them to explode with terrifying power in their bodies.

The warrior dragged into the corpse by the zombies disappeared without a trace in an instant, like a lump of meat thrown into a school of piranhas, and his shout seemed to have just reached his throat, and he didn't even have time to get it out of his mouth.

The companion who reached out to fish for him was so frightened by this scene that he froze there, and for a moment he was stunned, darkness enveloped him in as well. The last glimmer of light in front of him seemed to be tongues of fire coming from the muzzle of the gun, and then the sound of the gunfire disappeared into the warrior's ears, and he could not feel the sad cries of his fellow soldiers.

Seeing that there were two brothers missing from the team all of a sudden, Chen Bo's heart felt as if he had been slashed by a knife. Although he knew that their team was unlucky today, the feeling of being unable to do anything about his comrades sacrificing by his side made him very uncomfortable.

From the eight people who came in at the beginning, to the four left, Chen Bo didn't know how long his team could last. It seemed to him that perhaps the destination was on the seventh floor above, for the retreat below had been cut off, unless they were able to escape from the heavens.

The desire to survive and the soldier's dedication to completing the task drove these people to continue to run upstairs, and at this moment everyone had only one thought in their hearts, and that was to rush forward, although it seemed to them that there was no way to escape.

In the hall on the first floor, countless zombies were crowded at the door of the fire escape, and the passage was already crowded with zombies, and the forward of the corpse group still maintained a fast pursuit speed, and they bit behind the retreating team, getting closer and closer to them.

The long battle had consumed most of the warriors' physical strength, and now the retreat route was from the first floor back to the seventh floor, and running from the bottom to the top required much more energy than moving on flat ground. Moreover, the foul air and dim light in the corridor were also unfavorable factors restricting their movements, and the corpses chasing after them made people almost collapse.

The corridor on the seventh floor was already close at hand, Chen Bo heard the messy footsteps behind him, and the sound clearly reached his ears, and he didn't have to look back to know that the zombies were already very close to them.

With a "bang", Chen Bo slammed open the door of the corridor, and several people rushed out from inside. Chen Bo continued to run forward, and after running two steps, he suddenly found the footsteps of only one person beside him.

When he looked back, Chen Bo realized that the only person who was following him was Wang Jinxi, and the other two soldiers stopped at the door.

The two warriors threw their guns at Chen Bo and Wang Jinxi, and then worked together to close the door. The two of them leaned their backs against the door, blocking the zombies that had caught up behind the door.

The zombies in the corridor frantically banged on the door, and the other side of the gate was held up by two warriors to prevent the door from being rushed open by the zombies.

"Squad leader, Xiao Xizi, I don't have anything to worry about, just to help you delay the time," said the soldier who stood in the way, "If you can run out, remember to light one for me when you burn incense in the future, so that I can smile at Jiuquan." ”

As he spoke, he and the other warrior beside him looked at each other and smiled, both of them already gritting their teeth and pressing their milk against the door.

Chen Bo's teeth clenched together, and his gums were squeezing blood. These two soldiers were not old men who had been in his squad at the beginning, but the bloody nature and willingness to sacrifice their lives and death displayed today were completely worthy of their military status.

Chen Bo and Wang Jinxi caught the guns they threw and continued to run ahead, constantly searching along the road for places to hide.

After a while, the door behind him was slammed open, and only a loud "bang" was heard, and the two soldiers blocking the door were knocked out and flew out.

The two fell to the ground, and before they could get up, the next moment the zombies swarming out of the corridor drowned them in the crowd. Screams and curses came from inside, and for a while blood splattered, and the scene was unbearable to look at.

"It's over......, the team leader, there are zombie ...... in front", Wang Jinxi, who was running, suddenly stopped.
