The white eyes of hundreds of zombies stared at the human who had suddenly appeared at the gate of the rooftop for several years, and fell into silence for a moment.

If they still had consciousness, they would be grateful to this human, after all, they had been trapped here for too long.

But now, just for the next moment, the zombies let out a crazy roar, roaring and rushing towards the boy who suddenly appeared!

Shen Feng snorted coldly, and with a wave of his hand, he was about to control the gray tide and completely devour the zombies.

Nothing happened!

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

With a secret curse in his heart, Shen Feng immediately dragged the iron door over and slammed it shut, but it was already a little late, and a zombie at the front had already stretched out an arm to block the iron door.

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

With a soft sound of "chirp ......", the bones and musculature of the zombie's arm were directly shattered by the shotgun fired at close range, and the entire arm was cut off.

"Bang dang!" The iron door finally closed, and Shen Feng quickly inserted the iron rod and blocked all the zombies that rushed inside.

"Bang bang ......"

The sound of zombies banging on the iron door kept ringing, but fortunately, the iron door was almost two centimeters thick, and it was completely blocked by iron rods, even if these zombies had greatly increased their strength after mutation, they could not break open.

There are also several recessed craters in the iron gate, and it seems that there has been a fierce shootout.

After all, this is Mexico City, and the original purpose of the people who live here to install this iron gate should not be to prevent zombies, but to prevent gunfights between gangs.

Only then did Shen Feng discover that there was a dried corpse shrunk in the corner at the door.

The corpse also had a gun in its hand, two piercing holes in its temples, and deep bite marks on its arms.

It seems that when the plague broke out, this man led the zombies to the rooftop, closed the door, and finally killed himself with a gun before he was also infected.

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

At the outbreak of the apocalypse, I don't know how many people had flashed the brilliance of humanity and wanted to turn the tide, but in the end they could not compete with the general trend and ushered in the final failure.

Shen Feng then picked up the severed arm of the zombie that had just been broken by him and looked at it carefully, and found that it was similar to the zombie he had dissected just now.

Muscle tissue is also well-developed and active.

Even if it is interrupted, there is still a weak muscular nerve reflex at this time, and the fingers are still curling and stretching.

These zombies have been kept on the rooftop for at least a year, how the hell are they staying alive?

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

Shen Feng observed carefully, and then found a different place.

The surface of the severed arm's skin is gridded, similar to the fine folds on the surface of human skin, but it is extremely neat and has a faint dull golden metallic sheen.

Like a flexible metal film.

He peeled back the texture under the skin of the severed arm.

Nerves and muscles are connected, and they seem to be a little different from normal humans.

It seems that the degree of mutation of the zombies is also quite different, and the zombies on these rooftops seem to be further advanced than the female zombie that was dissected by him before.

Maybe you should open the door and find a few zombies to study it......

Shen Feng looked at the iron gate in front of him that was constantly shaking, and dispelled his thoughts.

Forget it.

This building is too low, so it's better to get a taller one.

Just then, a sudden sound of footsteps came from under the stairs.

A sturdy zombie wearing a gold chain that was obviously a gangster roared up from below and rushed towards Shen Feng!

Shen Feng raised the shotgun and stretched it forward, directly hitting the zombie's head and pulling the trigger.

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

Through the disappeared head, it turned out that another zombie was quickly climbing the stairs and rushing towards Shen Feng.

He frowned, came to the handrail of the stairs and looked down through the gap between the stairs, and saw that on the stairs below, there was a steady stream of zombies climbing along the stairs and coming towards him!

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

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

Shen Feng finally had a long-lost sense of tension at this time, took out a shotgun from his pocket, put it in the magazine, condescendingly aimed at the two zombies that were rushing up, and pulled the trigger.

"Chirp!" A touch of the steel ball instantly shot the head of the zombie in the front, and then beat the head of the zombie in the back into a sieve, and the two zombies immediately rolled to the ground and rolled down the stairs.

Only then a few more zombies climbed up the stairs.

Shen Feng didn't stop, but rushed towards these zombies head-on, with a grim face, and continued to pull the trigger, taking advantage of the attack area of the shotgun, and every shot was fired, trying to destroy the brains of two or three zombies.

You have to get out of here, the rooftop is full of zombies above, and the new zombies are constantly appearing below, once trapped here, it is a place of death!

Although Shen Feng was confident that he would be able to kill dozens of zombies with his bare hands even if he had no ammunition, these hundreds of zombies would definitely eat him to the point that there was no scum left!

After killing these zombies, a vacuum area appeared below, Shen Feng directly climbed over the handrail of the stairs, fell down to the lower stairs, and then continued to climb, and soon came to the corner of the stairs on the tenth floor.

There are especially many zombies here, and they can't go down again, so Shen Feng directly put the gun on the handrail of the stairs and continued to shoot with an expressionless face.

Zombies screamed and pounced, but they 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 zombie-paved road.

Seeing that there were zombies rushing up again, Shen Feng slammed open a door next to the stairs, rushed into a corridor, and firmly tied the door to block the zombies on the stairs.

"Roar—"

"Whoa...... Whoa......"

The zombies began to pound frantically on the hallway door, and the glass embedded in the center of the door quickly shattered, and it didn't take a few seconds to break through the door and rush over!

There were a lot of backs standing in the corridor at this time, and when they heard the sound from behind, they instantly opened their eyes and raised their heads, as if they had woken up from a dream, revealing a hideous look, and rushed towards Shen Feng!

Shen Feng rushed forward quickly with a shotgun, pulling the trigger as he advanced, like a ruthless killing machine, headshots the zombies that rushed over.

The nearest zombie was even shot in the face by him.

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

Soon Shen Feng had already come to the end of the corridor, the wooden-framed glass door behind him had been completely shattered, and the zombies on the stairs were frantically pouring over!

There were dozens of zombies that were killed, Shen Feng's shotguns had all been used up, unscrewed the silencer on the shotgun, threw away the gun body that had become scrap metal, took out the pistol with a silencer, and came to the elevator room while shooting headshots.

At this time, the muscles of his whole body bulged, the surface of his body petrified and hardened, and he had completely transformed into a combat form, and he threw himself directly in front of the elevator, and broke the elevator door with both hands, revealing a dark passage.

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

Seeing that the nearest zombies could rush over in less than ten seconds, Shen Feng no longer hesitated, jumped forward, grabbed the cable hanging the elevator car with his petrified palm and fingers, and quickly slid down.

The palm of his hand rubbed a spark on the cable, and Shen Feng fell heavily on the car at the bottom of the road, and with a "bang", he directly kicked the top steel plate of the car open and fell in.

After entering, I found that the surroundings were even more crowded than the morning rush hour buses, and there were all trapped zombies inside!

These zombies woke up suddenly, howling and stretching out their arms towards Shen Feng, wanting to bite Shen Feng.

One hand firmly grasped all parts of Shen Feng's body, trying to drag him over, and the nearest few even opened their mouths to bite, gnawing some gravel powder on Shen Feng's shoulders and neck.

Fortunately, although the strength of these zombies surpassed that of ordinary people, they were not as powerful as those zombies on the rooftop just now, and Shen Feng was still able to move his body.

His eyes widened, and he forcefully lowered the pistol to his neck, quickly pulled the trigger, and turned his body to pierce the zombies' close heads.

All the bullets in the magazine were empty, and even a richeting bullet grazed a wound on the surface of his body, and all the zombies in the elevator car had been shot in the head.

Then he vigorously opened the corpse in the car, walked to the door, opened the elevator door with a hole that could allow one person to pass through, and immediately squeezed out.

As soon as he entered and exited, he heard the sound of "bang bang bang" falling, and the zombies who were chasing him on the tenth floor actually began to jump directly into the elevator shaft like dumplings!

Fortunately, the corridor outside the elevator was empty, and there were no zombies, Shen Feng quickly changed a magazine and rushed out of the door of the building with a bloodstained backpack on his back.

There were several zombies wandering around the street at this time, and when they saw Shen Feng appear, they immediately roared and pounced.

Shen Feng didn't even look back at this time, he directly bypassed these zombies and rushed towards a building at the end of the street.

Glancing from the rooftop just now, he had already discovered that the tallest building in the neighborhood was the skyscraper!

If you want to see the whole of Mexico City, that's probably the best place to go.

And on the roof of that building, there was no trace of zombies.

There aren't many zombies on the street, but the skyscraper is an office building, and there should be a lot of zombies in it.

Shen Feng turned around and shot the head of the three zombies who were chasing after him as he ran, then stopped, tore off his shoes and threw them aside, wearing only socks, and running wildly.

The footsteps that were originally very eye-catching on the empty street disappeared immediately, and several zombies in the distance didn't even glance at Shen Feng, obviously they couldn't find out that he was human at all from a distance.

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

Forcefully open the elevator door, there were no zombies in the elevator car parked on the first floor, but several decaying corpses, the bones were broken in many places, and it seemed that the elevator fell out of control and fell to death.

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

Although this road is much more difficult, at least there will be no zombies.

And some of the steel beams around the elevator patio are able to stand, which can also give him a break in between.

Although his body has been mutated at this time, it is extremely powerful, but it is not a tireless perpetual motion machine, after all, he is still carrying all kinds of guns, ammunition and supplies, which is very heavy.

After climbing more than 20 floors, he already felt tired, so he hurriedly shook to the protrusion next to him and stood and rested for a while.

took out a bottle of pure water from his backpack and poured it into a bottle, and took out two more Mexican beef tortillas brought over and chewed them, the fragrant beef and the peppers inside brought a warm stream throughout his body in his stomach, Shen Feng felt his strength slowly recover, and immediately continued to climb up.

In the deep elevator patio, except for the sound of Shen Feng crawling, there was no sound, and it was terrifyingly quiet.

Shen Feng climbed for a while, feeling that he should put on music to ease the atmosphere, and said at the moment:

"Jingwei helps me ......"

Then he suddenly woke up, said no more, and controlled the silicon-based frame on his chest to play a soft Mexican guitar tune, continuing to climb in silence.

After playing a tune a few times and resting a few times, he finally came to the top.

jumped and slammed directly into the position of the elevator door.

"Bang dang!"

The elevator door was knocked out and flew out, and Shen Feng also fell heavily to the ground.

It was a hallway, and two dormant zombies immediately woke up and lunged at him.

Shen Feng got up and reached out expressionlessly to grab the necks of the two zombies, and threw them back hard, all of them into the elevator patio.

After a while, the sound of falling was heard, and he clapped his hands and stepped forward.

The top floor of the office building is lavishly decorated, and although there are some zombies, most of them are locked up in offices around the hallway, as if they were done when the people in the building were evacuated.

Shen Feng walked over barefoot at this time, basically without making a sound, and even held his breath, so he didn't alarm these zombies.

Soon he had found a small staircase and a door to the rooftop, opened the door, and finally reached the rooftop.

Unlike the building just now, it was empty and flat, and there were no zombies.

As the tallest building in the neighborhood, it overlooks the entire western region of Mexico City, and you can see the streets, buildings, and even the zombies that are roaming.

Shen Feng looked at this city that had become ruins, thinking of the prosperity of the original world of Mexico City before, and couldn't help but sigh in his heart.

Everyone is equal in the face of the plague, whether you are a member of the military and police, a gang member, a wealthy high-ranking official, or a common man.

Soon he had circled the west side of the rooftop, turned to the east, and looked towards the center of Mexico City.

The moment he saw that scene, Shen Feng's pupils shrank suddenly, a huge shadow appeared in his eyes, and the cold hairs on his whole body stood upside down, and he couldn't help blurting out:

"it!"
