Soon, one of the team members finally found a good descent spot with few zombies, he quickly tied the rope to the cold tower on the top of the building, pulled hard, and then shouted: "Captain, the rappelling rope is ready!" ”

"Quick, throw all the grenades out!" Bai Yu immediately commanded, and the pipe in the passage of the first unit quickly took out a white phosphorus grenade, bit open the safe, and signaled that the brother on the side was the same as him.

"Ready, 1! 2！ 3！ Throw! Hearing Bai Yu's words, seven white phosphorus grenades and eight fragment grenades, the three channels that could come up were thrown down, and the first thing everyone did after throwing them was to run towards the rappelling rope quickly.

First, there was a violent blast of fragmentation grenades, and then white smoke suddenly spread under the mutants' feet, and more than a dozen orange flames rose into the sky, and the thick smoke filled the top floor.

Almost at this point, the temperature of up to 1,000 degrees was suddenly ignited, and the mutants within dozens of meters devoured and melted, and countless small flames flew everywhere, as long as the mutants were touched a little, the high-temperature white phosphorus would burn through the skin and flesh, and penetrate deep into the bone marrow, and all the mutants who were about to reach the top floor seemed to be in a high-temperature furnace, burning not even slag.

The mutants roared and were burned alive, causing the smell of barbecue to waft from the pungent stench of corpses and the heavy smell of blood in the building.

Due to the dense crowding, at least more than 700 mutants were burned alive, and some of the burned mutants were on fire, like a humanoid torch, running around in a panic, and then igniting the clothes of other mutants, scorching flesh and blood, and the mutants all over the building let out a terrifying howl.

The people on the roof didn't bother to watch a feast of fire or listen to the crackling of fat and flesh as the torch burns with hundreds of mutants. Automatically form a defensive formation in case of a sudden surprise attack by mutants.

Bai Yu immediately arranged: "Leave four people, the others immediately press up and retreat, pay attention to your feet, mutants don't like you to step on their heads!" ”

Chu Yunlan put the anti-materiel sniper rifle on her shoulder, and was the first to start rappelling.

Fifty floors, the high-altitude air current was already strong, but this did not prevent her from sliding quickly, and on another rappelling rope, the eight people on the side of the pipe also carried weapons on their backs and jumped down.

"All of them—" The four tattooed men left at the entrance of the last rooftop passage were not deceived by the scimitar shadow species lurking in the shadows and slowly approaching, and a series of ferocious firepower swooped down on the other scimitar shadow species that shrank into a ball and used the shadows to be cunning.

"Roar!" Incredibly, the shadow species actually used a scimitar to protect its head, and several screaming bullets slammed into it, causing a spark, but it didn't kill it!

As for the few shots that hit the body, the shadow species didn't care at all, and simply roared and slowly pressed towards everyone.

"Kill!" As if to show his bravery in front of Bai Yu, a short-haired team member suddenly raised his submachine gun and kept shooting wildly.

The scimitar shadow double knife head guard, only to hear the tinkling sound, a full sixty bullets, all blocked, the analyst was surprised to close his mouth.

The twin knives flashed out, sticking out a bloody paste, the whole face like a tomato that had been trampled on, a face with rotten flesh and bumps, and the steel teeth that are essential to every shadow species, and it was a roar of rage at everyone!

"Phew!" With a precise shot, the heart of the mutant who was so proud of blocking countless bullets and intimidating everyone was shattered.

The short-haired team member looked at Bai Yu on the side, still in a shooting form.

Pipe, who was in no mood to pay attention to these also alien soldiers, immediately ordered the prisoners behind him to go downstairs.

Chu Yunlan and the three prisoners below had already cleared out the few mutants in the vicinity and opened a way out.

Looking at the descending humans, the tentacle mutants hidden downstairs seemed to guess their behavior, opened their mouths and let out a silent laugh, their fierce and bloodthirsty eyes moved, and countless mutants who rushed upstairs seemed to be puppets with strings, turning around inexplicably, and running down frantically!

"Quick, there's two buggies out there!" Pipe saw more and more mutants coming in, and understood that it was the mutants upstairs who came down in a swarm again, and he was anxious, and it happened that he saw the car wash room thirty meters downstairs, there were two off-road vehicles, and he immediately called out in surprise. As long as you can run over and start up, you can rush out of this mutant crowd!

After Bai Yu and the tattooed man came down, everyone was already running hard, firing from time to time, blasting the mutants who rushed up madly, and the whistling panting and crisp and loud gunshots became heavier and heavier in this broken ruined city.

It turns out that upstairs, you can also rely on stairs for defense. And when it goes down to the ground, the defense area has been greatly increased, and it is no longer possible to form suppressive firepower, so you can only rely on everyone's marksmanship and crazy running to block the yin wind blowing from the god of death for their own life fire.

In just a few breaths, seven prisoners were ambushed by xenomorphs hidden in the shadows, killed instantly, and even screamed, everyone ran desperately, and the pipe was running at the front, he knew that in the face of mutants, sometimes he could escape by not running fast, but as long as he ran faster than his teammates, his chances of survival would be much greater.

Naturally, the prisoners understood this, and they all ran ahead of the others.

The closer you get to the hope of life, the bigger the gap in this defense. The mutants, with a speed far higher than usual, chased after those who were also crazy, ignoring the flying bullets and the roaring grenades, the mutants let off a terrifying howl and rushed towards the humans behind.

The first to arrive at the off-road vehicle was Chu Yunlan and the analyst, she shook her hand and cleared the dozen or so mutants blocked by the side of the off-road vehicle, got into the car, and started the off-road vehicle.

Then arrived the pipes and the others, who stood next to the buggy, raised their weapons and unleashed their guns!

"Da Da Da!" The dense network of fire slanted down, and in a terrifying roar of metal, it flew away, like a nine-day fire dragon, blocking the tide of mutants, and beating them into minced flesh and blood clots without mercy and indiscriminately!

That hysterical scream was generated in the mutant crowd, and countless mutants were beaten into a pile of flesh and blood in this way, almost unable to make up a human form!

Coupled with individual guns and howitzers, the assembled firepower network welcomed Bai Yu and the others who left last into the convoy, and the endless tide of different species was no longer something that these few guns could keep.

The tentacle xenomorph who had been hiding in a dark corner and had refused to show up saw everyone rushing to the area where the Humvee was parked, and was furious, and an extremely sharp whistle resounded in the night sky.

The mutant who was pressed by the black pressure was even more desperate, as if he had been beaten with a sharp agent, and moved forward frantically, the trembling Wei Wei's steps became faster and faster, and even the mutant who was broken by a stray bullet crawled on the ground with his hands, drawing a clearly visible, slippery and disgusting blood path.

"Hurry up, let's go! Knock these goddamn mutants to death! "The pipe sat in the car and twisted the key that had not been removed from it.

"Boom!" Two fragment grenades were thrown into the mutant crowd, causing two more bursts of flames and black smoke to rise into the sky, blowing up a field of mutants, splashing countless mud, and smashing out two large craters, revealing the color of the ground.

Stumps were flying, flesh and blood were overwhelming, and more than a dozen mutants with missing arms and legs were flying high in the air, waving their skinny arms in horror that were the same as those of Somali refugees, with a long "hiss" sound, and the broken strings fell rapidly like kites, and the bodies were covered with black blood splashing everywhere.

"Hurry, hurry! Start the fuck! The prisoners screamed in fear and unease, and the sound of the intense roar of strafing became staccato and it was clear that they were seriously running low on ammunition.

"Damn, why don't you start the car yet? If we keep doing it, those monsters will drown the six of us! Inside the first SUV, the pipe pointed at the tattooed man who was driving.

"Launch, !!!!" The tattooed man was sweating profusely, his muscles bursting, and he writhed his car keys desperately.

But their off-road vehicles couldn't catch fire!

Seeing that something was wrong, the pipe glanced at the person next to him, and the two opened the car door and ran towards Bai Yu's off-road vehicle.

The other four people were not stupid, picking up the empty weapon was like a baseball bat weighing a few pounds, knocking several mutants who rushed over to the ground, their heads were bleeding, and they rushed towards the off-road vehicle of Bai Yu's team with the pipes running with all their might.

But before the three of them could go far, they were caught up by the mutants who were blocking in the middle, and they were devoured in a blink of an eye. And the tattooed man who just wanted to start the car on fire was trembling to find that because of the force, the car key was inexplicably broken in two!

", what's going on?" He screamed in despair, and suddenly realized that he was the only one left in the car!

The mutants rushed in frantically, howling and banging on the car windows, sharp nails, making a "squeak" sound on the car windows.

Only then did Bai Yu realize that there were still people still in the car that was not on fire, so he took out the Blade Killing Rainbow Knife, wanting to kill a bloody path, but there were too many mutants, so many that it was suffocating.

It was too late, and hundreds of mutants had already crawled all over the buggy, swaying it from side to side.

The pipe that ran over hurriedly shouted, "Let's go! There's no way around it! ”

The team members behind him also chimed in: "Captain, let's go, if you don't leave, you won't have a chance!" At the end of the day, the fear in the soul no longer needs to be explained.

Gritting his teeth and stepping on his feet, the off-road vehicle screamed and rushed out, crashing into countless mutants along the way.

All of them were gone, leaving only the poor and hapless tattooed man trapped in the overturned SUV.
