In the pipeline, Chen Hang took the lead, the grass field was in the center, and after the palace of Verille, everyone climbed towards it, and this time the crawl was much smoother.

All three of them had been trained, and all three of them were of outstanding physique, and they quickly climbed to the position of the forty-seventh floor, and Chen Hang, who led the team, suddenly stopped.

The grass field was unknown, but through the gap he could see that there was nothing in the metal passage.

Seeing Chen Hang put his ear against the metal wall, he quickly raised his head, and Chen Hang's eyes were staring at the end of the passage.

Now, even the grass field and Verelle behind them could hear the sound, and the sound of "rustling" kept coming, it was the sound of small animals running inside the ventilation pipes.

"What's going on, what's going on?" Kusada began to panic, and just as he was about to retreat, he heard a "clang" and a corpse rat crashed out of the corner at the end of the passage.

The corpse rat was extremely fast, its limbs were running wildly in the ventilation pipes, the flesh on the corpse rat was all rotten, it was basically a mouse skeleton, only its internal organs were left to rise and fall in the abdominal cavity with its running rhythm.

"Zombies, zombies, let's retreat, retreat." Kusada was completely panicked, and he immediately stepped back, but Verelle behind her was stubbornly resisting, and she had already pulled out her pistol.

"It's too late, prepare to fight the enemy."

Before Verelle's words fell, there was another "sonorous" sound, and the second corpse rat rushed out of the passage, its body rotted even brighter, the corpse rat hit the metal wall hard, it bounced back, and then the two corpse rats rushed towards Chen Hang one after the other.

Chen Hang held his breath, he held the steel drill in his hand very tightly, and Chen Hang's eyes were fixed on the corpse rat's body.

The two corpse rats began to sprint, the running mouse skeleton shuddered to watch, the grass field had stopped shouting, and his hand axe had been raised.

When the first corpse rat rushed to a distance of one meter from Chen Hang, he saw its white bone hind legs kick hard, and the corpse rat jumped up, and it pounced on Chen Hang.

With a "whoosh", I saw a black light flash, and then there was a "clang" sound from the metal channel, and Chen Hang pierced the steel chisel out, and the steel chisel accurately penetrated the body of the corpse mouse, and then nailed it to the metal wall.

The second corpse rat was also not slow, it had already jumped up, and saw Chen Hang pull it out with a backhand.

With a "snap", there was a vibration on the metal pipe wall, and the back of Chen Hang's hand left the passage, leaving a pool of broken bones below, and the corpse rat had been photographed by Chen Hang as "pink".

Chen Hang looked at the back of his hand, there was a layer of scaly things that were slowly disappearing, and they finally disappeared, and this layer of scaly objects even crushed the teeth of the corpse rat.

The second gene, Chen Hang still doesn't know what it is after two lifetimes. Chen Hang had already inspired it in the previous life, but until the end, Chen Hang couldn't see its final form, this gene was the most mysterious, and its aggressiveness made Chen Hang very frightened.

Is it that my abilities are not enough to fully inspire you?

Chen Hang smiled, he continued to climb out towards the front, and the grass field behind followed.

Looking at the broken bones on the metal wall, Cao Tian was secretly frightened: This Chen Hang must have reservations, I have to be careful.

The team continued to move forward, and they soon reached the location of the fifty-first floor, from which the ventilation ducts of the building were inexplicably severed.

"What's going on? Are there any special designs for these floors? Chen Hang asked behind him. Kusada replied in a whisper: "I don't know, but these floors belong to a mysterious physics laboratory, and maybe the renovation here is related to this laboratory." My people are hiding in the warehouse of this lab. ”

Chen Hang snorted, he carefully observed below, and then Chen Hang pressed his right hand on the metal pipe wall.

Chen Hang's right hand began to change, his fingers began to lengthen, the scaly object grew, the nails of the fingertips stretched into the shape of curved hooks, a layer of mucous membrane appeared between the fingers, and the lizard-like claws appeared on his wrists.

All these changes were blocked by Chen Hang's body, and the grass field behind him could not see these changes, he only heard the sound of cutting metal.

Chen Hang's claw grabbed down the ventilation duct, and as the claw scratched it, the metal pipe wall was cut open by it like a piece of paper, revealing a huge gap underneath.

When cut to a sufficient width, this claw held on the upturned metal strip, it was not afraid of the sharpness of the metal at all, Chen Hang grabbed the metal and pulled hard, and heard the sound of "creaking" kept coming, and the ventilation pipe was completely torn open by Chen Hang.

Chen Hang jumped out of the crack, followed by Cao Tian and Verelle, and they landed in a small room.

It was a storage room used by the cleaners, and it was very cluttered, and the door of the room was open, but fortunately no zombies entered.

Chen Hang nodded, and he took the lead out of the room, and the team ran towards the stairs upstairs. No one noticed that a zombie was climbing upside down on the top of the corridor, it was supporting itself with its hands and feet, and the zombie's stinky body was pressed upside down against the top of the wall.

It has found people who have walked by.

As soon as the zombie's feet loosened, it fell from the top of the hallway, and the zombie landed very softly on the ground, and it followed at the end of the group.

When Verelle rushed into the stairs, the zombie quickened its pace, and it was very close to Verelle.

The zombie stretched out its claws, and it grabbed Wei Rui'er suddenly, and at this time, I saw Verelle's right hand suddenly raised, and the chopping knife in her hand swept past the zombie's neck, and the zombie's head immediately turned on its neck.

After the head had turned three times, it finally slowly stopped, and the zombie lost its life and fell to the ground.

Kusada looked at Verelle in surprise, he hadn't noticed the existence of the zombie all the while. It wasn't until Verelle suddenly struck out to kill the zombies that he knew that the team was being followed by monsters.

"Level 2 zombies will become more powerful, we have to be very careful." Chen Hang was also secretly frightened, he was also negligent just now. In his previous life, he had already stimulated the four genes, and Chen Hang was deaf and clear-sighted at that time. Now that his soul has been reborn, Chen Hang still maintains the habits of his previous life, and he is still too careless to see himself.

Perhaps, stimulating more genes is the best way to survive in the apocalypse.

The three of them rushed up to the second floor in one go, and they finally reached the position of the fifty-third floor, where they saw a different design from the other floors.
