The zombies flooded down the corridor below, disappearing at the end of the passage, and silence was restored.

Two minutes later, the "canopy" slowly stretched out a tentacle like a snail's tentacles, which slowly extended along the roof of the porch, and this tentacle reached the inside of the open door—an eye opened from the top of the tentacle.

This is still the natural ability of the octopus, Chen Hang is the first time to use the ability of the new gene in this way, he feels that the deformed limbs are a little painful, but using this method, Chen Hang can see the back of the gate very covertly.

At this time, the last zombie in the inner room rushed out of the inner cabin, it hit the iron door, the iron door hit the wall of the passage, the iron door rebounded, and with a "squeak" it closed again, and immediately clamped the tentacles that Chen Hang had deformed inside.

"Wow!"

That pain, Chen Hang almost screamed on the spot.

The zombie rushed in such a hurry that it didn't notice what was happening overhead. When the zombie disappeared at the end of the corridor, the "roof of the corridor" softened, and Chen Hang stood on the ground with grinning teeth.

He hurriedly opened the iron door, and the part of his body that had been caught shrank back. The tentacle had been pinched and distorted.

"Oh, oh, oh, oh......" Chen Hang screamed again and again, and the tentacle slowly retracted into his body, everything is really unfavorable today!

Chen Hang sighed, and then rushed to the inner cabin, before he could be sure that there were no zombies here.

This chamber is next to the nuclear reactor behind it, and it is the closest control room to the nuclear reactor, where the temperature has risen to about 20 degrees.

By this time, the environment inside the chamber had changed, and a large number of hard-shell-like things were piled on the ground, they were threaded, and they looked like the shells of giant snails, which were very strange.

These things are not the remains of human flesh and blood, these hard-shelled things are formed by the hardening of some kind of slime, and most of the snail shells have a hole in them, and there are hardened dry wires in them that have been dragged to the ground, and it is clear that what was hiding in the shell has long since come out.

Corpse Cocoon! Chen Hang recognized this kind of thing at a glance, this was indeed the advanced nest of zombies, and those fourth-level fusion zombies ran out from here.

The so-called corpse cocoon means that after the zombies reach the third level, they will begin to try to attack the high-level, so the third-level zombies will begin to capture the low-level zombies.

While fusing low-level zombies, they secrete a large amount of slime, which is highly corrosive, and they will slowly wrap around the zombies and wrap the zombies in the fusion.

Then the zombies in the fusion will hide in the corpse cocoon to complete the final evolution, when they are fused, the new zombie will break the corpse cocoon and drill out of it, at this time it has completed the evolution and become a new level 4 zombie.

Chen Hang looked up and carefully observed a corpse cocoon hanging on the roof, this corpse cocoon was still intact, it occupied a corner of the roof, the shell of the corpse cocoon had hardened, it corroded the steel there, the steel was connected to the hard shell, and it looked like a huge beehive.

This corpse cocoon is the only complete corpse cocoon here, the zombies inside have not yet been fused, Chen Hang can hear the faint sound of "creaking" from the corpse cocoon.

Taking a gentle breath, Chen Hang walked over slowly, he raised his right foot, and the sole of his foot stood on the vertical wall like a suction cup, and then Chen Hang's left foot was raised.

Like a leisurely stroll, Chen Hang walked up step by step along the ninety-degree wall, and he silently walked to the edge of the corpse cocoon.

Judging the situation inside the corpse cocoon again, Chen Hang slowly stretched out his left hand, and the index finger of his left hand slowly stretched out.

I saw that the finger was getting longer and longer, and the longer and sharper it became, Chen Hang's index finger stretched out to about a meter, and it turned into a sharp spike, and Chen Hang put the spike on top of the hard shell.

The sound of "zi, zi" came slowly, and the spikes made a circle on the top of the hard shell, and the huge hard shell was cut open by Chen Hang.

As the hard shell that was cut peeled off, with a "bang", a large puddle of slime flowed down, and they pulled out filaments in the air, and the slime flowed all the way to the ground, and the iron floor on the ground was suddenly corroded with a "zizi" sound.

As the slime flowed away, two skeletons were revealed, two human skeletons curled up together, the larger one enclosing the smaller one, and half of the smaller skeleton's head had disappeared.

This is exactly an evolving zombie, the small zombie has been half melted by the big zombie, and this zombie is about to complete the fourth level evolution.

Sensing the change in its environment, the evolved zombie opened its eyes, and it saw a long thorn aimed at its white eyeball.

I heard a "poof", and within the zombie's reaction, the long thorn pushed forward, and the zombie's eyes exploded like berries.

As the long thorn went forward, it plunged deep into the zombie's skull, and the brownish-green brain gushed out of the zombie's skull along the gap.

Chen Hang continued to exert his strength, he could feel his fingers piercing into the steel, Chen Hang stirred left and right, and only after making sure that the zombie was completely dead did he pull the long thorn out of the zombie's eyes.

The long spines were stained with pale green slime, which was the mutated human brain tissue. From level 4 onwards, the brains of the zombies begin to change, they change their composition, and the rotten brain tissue begins to divide again, and these zombies have become completely different.

Chen Hang put the hard shell back on, and saw him jump slightly, Chen Hang fell back to the ground, and he began to check the circuit in the control room.

According to Annie's analysis, the aircraft carrier's control circuit is faulty here, and Chen Hang needs to find this fault to troubleshoot it, so that Annie can regain control and drive the aircraft carrier.

Seeing the situation in this control room, Chen Hang immediately understood the problem - the slime secreted by the zombies corroded the wiring groove here, and the wiring must have been broken by the zombies somewhere.

Carefully shoveling up each corpse cocoon, Chen Hang quickly found the fault - in the corner under the console, there was a corpse cocoon, which corroded the trunking shell there, and the wiring inside was completely broken.

Chen Hang found the accessories, he quickly repaired the wiring here, and the indicator light on the console turned on again.

"Anne, Anne, can you hear me? Can you hear me? Chen Hang activated the intercom device here, he called a few words in a row, and Anne's voice soon came from inside: "Received, received." Very good, Chen Hang, the fault prompt is gone. Be right back. ”

Chen Hang smiled and nodded, he turned off the walkie-talkie, and just as Chen Hang was about to turn around and go back, he unexpectedly glanced at the sealed door, and Chen Hang's face changed instantly.

The sealed door, the passage to the nuclear reactor, was somehow opened.
