Hundreds of zombies had pale eyes staring at the human who had suddenly appeared at the door of the rooftop for several years, and briefly fell into silence.

If they still have consciousness, they will definitely be grateful to this human being at this time, after all, they have been trapped here for too long.

But now, just the next moment, the zombies roared wildly and rushed towards the boy who suddenly appeared!

Chen Feng snorted coldly, waved his hand, and wanted to control the gray tide to completely swallow the zombies.

Nothing happened!

I am used to using gray tide, and forgot about the fact that gray tide has been disconnected for a while!

He cursed in his heart, and Chen Feng immediately pulled the iron gate over and closed it suddenly, but it was a little late. The zombie in front had already poked out an arm and blocked the iron gate.

Chen Feng immediately raised the shotgun in his hand and pointed it at the zombie's arm and pulled the trigger.

"Chir..." With a light sound, the zombie's arm bones and muscle tissue were directly shattered by the shotgun shot from close range, and the entire arm was cut off.

"Bang!" The iron gate finally closed, and Chen Feng quickly inserted the iron rod and blocked all the zombies that rushed over.

"Bang bang bang bang bang..."

The sound of zombies hitting the iron gate kept ringing. Fortunately, the iron gate was about two centimeters thick and completely blocked by iron rods. Even if these zombies have increased their strength after mutating, they cannot break open.

There were several recessed craters on the iron gate, and there seemed to have been a fierce gunfight.

After all, this is Mexico City. The original purpose of people living here to install this iron door should not be to prevent zombies, but to prevent gunfights between gangs.

Chen Feng then discovered that there was a mummy huddled in the corner at the door.

The corpse also held a gun in his hand, with two piercing holes in his temple and deep bite marks on his arms.

It seemed that when the plague broke out, this person led the zombies to the rooftop and closed the door. Finally, he raised his gun and committed suicide before he was infected and started to get sick.

Chen Feng couldn't help but sigh, this person is also a hero.

When the catastrophe broke out, I don’t know how many people shone with the glory of human nature and wanted to turn the tide, but in the end they were unable to compete with the general trend and ushered in the final failure.

Chen Feng then picked up the broken arm of the zombie that he had just interrupted and looked carefully, and found that it was almost the same as the zombie he had just dissected.

Muscle tissue is also very developed and active.

Even if it was interrupted, there was still a faint muscle nerve reflex at this time, and the fingers were still curling up and stretching.

These zombies were locked on the rooftop for at least a year. How did they stay active?

Pure intake has no output, and it does not conform to the law of conservation of energy at all...

Chen Feng observed carefully and then found a different place.

The skin surface of this broken arm is grid-like, which is actually similar to the subtle folds on the surface of human skin, but is extremely neat and has a faint dark gold metallic luster.

Like a flexible metal film.

He peeled off the texture under the skin of the broken arm again.

The nerves and muscles are connected, which seems to be somewhat different from normal humans.

It seems that the degree of mutation of zombies varies greatly. These zombies on the rooftop seem to be further than the female zombie he had dissected before.

Maybe you should open the door and find out a few zombies and study them carefully...

Chen Feng looked at the iron gate that was constantly shaking in front of him, and gave up his thoughts.

Forget it.

This building is too short, it would be better to change to a higher one.

At this moment, a sound of footsteps suddenly came from below the stairs.

A zombie with a strong figure wearing a gold chain during his lifetime was obviously a gangster, roaring and rushing up from below and pounced towards Chen Feng!

Chen Feng raised the shotgun and stretched forward, pressing directly against the zombie's forehead and pulled the trigger.

"Puff..." The black brain and skull fragments scattered backwards, and half of the head disappeared directly.

Through the disappearing head, another zombie was quickly climbing the stairs and pounceing towards Chen Feng.

He frowned and came to the handrail of the stairs to look down through the gaps between the stairs. He saw that on the stairs below, there were continuous zombies climbing along the stairs and coming towards him!

It seems that the zombies in the entire building are coming!

Obviously, these zombies were attracted by the sound of the iron gate!

Chen Feng finally felt a long-lost tension at this time. He took out a shotgun from his pocket, put it into the bullet compartment, aimed at the two zombies that were rushing up, and pulled the trigger.

"Chir!" As soon as the steel ball touched the head of the zombie in front was instantly shot, and then the head of the zombie behind it was sieve. The two zombies immediately rolled to the ground and rolled down the stairs.

But then a few more zombies climbed up the stairs.

Chen Feng did not stop, but rushed towards the zombies with a cold face, continued to pull the trigger, and took advantage of the shotgun's attack area to destroy the brains of two to three zombies as much as possible for each shot to be shot.

You must leave here. Above is the rooftop full of zombies, and below are new zombies that are constantly appearing. Once you are trapped here, you will die!

Although Chen Feng was confident that he could kill dozens of zombies without ammunition, these hundreds of zombies would definitely eat him without even losing his scum!

After killing these zombies, a vacuum area appeared below. Chen Feng directly crossed the handrail of the stairs, jumped to the lower stairs, and continued to climb over. He soon arrived at the corner of the stairs on the tenth floor.

There were particularly many zombies here and could no longer go down again. Chen Feng directly put the gun on the handrail of the stairs and continued to shoot expressionlessly.

Zombies pounced on them wailingly, but were destroyed by headshots and rolled down the stairs.

The corner of the staircase below is filled with zombies with destroyed brains, and the staircase has become a paved road for zombies.

Seeing another zombie pounced above, Chen Feng suddenly knocked open a door next to the stairs, rushed into a corridor, and tied the door firmly, blocking the zombies on the stairs outside.

"roar--"

"Crazy...Crazy..."

The zombies began to hit the corridor door wildly, and the glass embedded in the center of the door quickly shattered, and it would break through the door and rush over in a few seconds!

There were many backs standing in the corridor with their heads hanging down. When they heard the sound coming from behind, they instantly opened their eyes and raised their heads, as if they woke up from a dream, showing a ferocious look and rushed towards Chen Feng!

Chen Feng rushed forward quickly with a shotgun, pulling the trigger while moving forward, like a ruthless killing machine, slashing the zombies rushing over.

The closest zombie was even shot directly in the face by him.

At the same time, he was quickly observing the reactions and characteristics of the zombies around him and keeping them in mind.

Soon Chen Feng had arrived at the end of the corridor. The wooden-framed glass door behind him had completely shattered, and the zombies on the stairs rushed over!

There were dozens of zombies killed, and Chen Feng's shotgun had been used up. He unscrewed the silencer on the shotgun and threw away the body of the gun that had turned into scrap iron. He took out the pistol equipped with the silencer and shot the headshot while coming to the elevator.

At this time, his muscles were bulging, his body surface became petrified and hardened, and he had completely transformed into a combat form. He rushed directly to the elevator and opened the elevator door with both hands, revealing the dark passage.

Looking down, the elevator car is on the first floor.

Seeing that the closest zombies could rush over in less than ten seconds, Chen Feng no longer hesitated, jumped, grabbed the cable that hung the elevator car with his petrified palms and fingers, and quickly slid down.

A series of sparks were drawn on the cable with his palms, and the sunken edge fell heavily on the car on the bottom floor. With a "bang", he kicked the steel plate on the top of the car and fell into it.

After entering, I found that the bus around was even more crowded than the morning rush hour bus, and it was full of trapped zombies!

These zombies suddenly woke up and howled and stretched out their arms towards Chen Feng, trying to bite Chen Feng.

He firmly grasped Chen Feng's body with his hands and wanted to pull him over. The closest few even bit him and bit him, chewing some gravel powder on Shen Feng's shoulders and neck.

Fortunately, although the power of these zombies is greater than that of ordinary people, it is not as powerful as those on the rooftop just now, and Chen Feng can still move his body.

He widened his eyes and pressed the pistol flat to his neck with force, quickly pulled the trigger, and turned his body to penetrate the zombies' heads close to him.

All the bullets in the magazine were shot out, and even a jumper wiped a wound on the surface of his body. All the zombies in the elevator car had been shot.

Then he pulled open the body in the car with great force, walked to the door, opened a hole that could accommodate a person through, and immediately squeezed out.

As soon as I went in and out, I heard the sound of "bang bang bang" falling. The zombies who were chasing him on the tenth floor actually started to jump into the elevator shaft like dumplings!

Fortunately, the corridor outside the elevator was empty and there were no zombies. Chen Feng quickly changed a magazine and rushed out from the entrance of the building with a blood-stained backpack.

There were a few zombies wandering on the street at this time. When they saw Chen Feng appear, they immediately roared and rushed over.

Chen Feng didn't even look back at this time, and he went around the zombies and rushed towards a building at the end of the street.

I glanced at the rooftop just now and he had already discovered that the tallest building nearby was the skyscraper!

If you want to observe the situation in Mexico City, it should be the best place.

Moreover, there were no traces of zombies on the rooftop of that building.

There are not many zombies on the street, but the skyscraper is an office building, and there should be many zombies inside.

Chen Feng turned around and shot the three zombies who were chasing him reluctantly, then stopped, pulled down his shoes and threw them aside, put only socks on, and ran forward wildly.

The footsteps were strikingly striking on the empty streets immediately disappeared, and the zombies in the distance did not even look at Chen Feng. It was obvious that he could not be discovered that he was a human being at all because of the distance.

Finally, Chen Feng rushed into the office building, killed two zombies in the hall, and came to the elevator.

He opened the elevator door hard, and there were no zombies in the elevator car parked on the first floor, but several decayed corpses, with many broken bones, as if the elevator fell out of control and fell to death.

Chen Feng climbed up directly along the broken top of the car, found the steel cable, and then began to climb up little by little.

Although this road is much harder to walk, at least there will be no zombies.

Moreover, some steel beams around the elevator patio can stand, so that they can also rest in the middle.
