But the mutation beneath the black obelisk isn't over yet.

The zombies transformed by human survivors stood up and broke free from the ropes that bound their hands and feet as soon as they stood up.

Then these zombies, who had just been transformed by human survivors, immediately pounced on the zombies who had just bitten them to death.

And the zombies who slaughtered all the survivors just now rushed forward not to be outdone.

Below the black obelisk, it instantly became a battlefield of flesh and blood, and the zombies on both sides constantly attacked their kind.

In the process of attacking each other, black blood and all kinds of minced flesh splashed outward from time to time, and the roars of the battlefield one after another also continued to sound.

"Boss, what's going on? Could it be that the human survivors who were killed just now still have memories, and they want to get revenge on the zombies who killed them? Wu Yuli looked at the bottom of the valley, the chaotic scene, and was also quite puzzled.

"Look, I'm not sure what's going on."

Although Han Feng has quite a lot of experience in surviving in the last days, he can only guess that the behavior of the zombies in the valley attacking each other should be affected by the biological gene mutation generator, but what will happen in the end, he is not very clear.

The Unimog RV on the hillside stopped quietly in place, and after waiting for about five minutes, the battle of the zombies fighting each other in the valley also came to an end.

At this moment, in front of the obelisk, only four zombies stayed in place, and after they glanced at each other, they finally stopped fighting.

Then the four surviving zombies, almost at the same time, raised their heads and roared towards the position of the black obelisk.

"It's!"

While the four zombies roared, Han Feng stood up suddenly.

He saw that on the black obelisk, there was a trace of energy fluctuations, and the target of this energy fluctuation was the four zombies that kept roaring under the obelisk.

And the four zombies gathered under the obelisk and kept roaring, after receiving this energy, their bodies immediately underwent drastic changes.

The body of a male zombie, like blowing up a balloon, suddenly began to expand outward, and in the blink of an eye, the height of this male zombie broke through three meters and five, turning into a giant zombie.

At the same time, the bones in the body of a female zombie slowly grew longer, and continued to expand outwards until the bones pierced its skin, and sharp bone spurs protruded from its body.

"The role of this biological gene mutation generator is to help zombies evolve!"

After Han Feng saw four ordinary zombies that had evolved into bronze-level mutant zombies, his eyes couldn't help but widen, and the shock in his heart couldn't be expressed in words.

The fifty human survivors just now, plus fifty ordinary zombies, after fighting each other, the biological gene mutation generator actually gave birth to four bronze-level mutant zombies among them, which is too amazing.

Under normal circumstances, the chance of ordinary zombies converting into mutant zombies is only one in a few thousand, but after the intervention of the biological gene mutation generator, this number immediately soared to one in twenty-five.

Although in this evolutionary process, other ordinary zombies will be used as stepping stones for mutated zombies.

But if this evolution probability is followed, it won't be long before the Tiger City corpse group will have thousands of bronze-level mutant zombies, which is completely unacceptable to Han Feng.

Thinking of this, a hint of fierceness flashed on Han Feng's face, he barely thought about it, and directly exchanged a place with Wu Yuli and sat in the driver's seat of the Unimog RV.

Then he shifted the position of the RV slightly, so that the front of the Unimog RV was aimed at the black obelisk in the middle of the valley, and after a moment, he directly pressed the launch button of the Heavenly Punishment Particle Plasma Cannon.

A dazzling light appeared on the roof of the RV, and the stream of yellow and red particles instantly shot out from the barrel of the roof of the RV, and the ferocious fire pointed directly at the black obelisk in the middle of the valley that was suspected to be a biological gene mutation generator.

When the Heavenly Punishment Particle Plasma Cannon shot out a stream of deadly particles, in the mountains and forests not far from the black obelisk, Wang Yi's head suddenly raised and looked at the location of the black obelisk.

And standing in front of Wang Wei's body, a zombie with dark red skin also raised his head suddenly, and the fierce light in his eyes obviously continued to overflow.

"This neighbor of ours really has the capital to kill gold-level mutant beasts."

After faintly seeing the scene of the Heavenly Punishment Particle Plasma Cannon firing from the gap in the trees, Wang Yi nodded his head slightly, and a solemn look appeared on his face.

And the zombie with dark red skin standing in front of Wang Wei kicked his feet on the ground, intending to rush towards the Unimog RV that shot the Heavenly Punishment Particle Plasma Cannon.

"Kondesack! Calm me down! After Wang Yi felt the movement of the dark red-skinned zombie beside him, a low roar also sounded in his throat.

The zombie who was originally going to rush towards the Unimog RV, after hearing Wang Yi's low roar, the entire forward momentum instantly slowed down, and his body immediately stopped.

"Ayebuda, although you are the ruler of the zombies in this area, I have now successfully advanced to gold, and I am no longer an ordinary zombie who was confused before, and you can no longer order me like before."

The zombie with dark red skin, although it obeyed Wang Rei's order and stopped its progress, it was obviously dissatisfied with Wang Rei's order.

Just when Wang Yi and Kandesak in the mountains and forests had a small contradiction, the Heavenly Punishment Particle Plasma Cannon shot by the Unimog RV accurately hit the black obelisk more than ten meters high.

However, when the stream of yellow and reddish particles hit the black obelisk, a transparent film of light emerged from the inside of the obelisk and firmly wrapped the body of the obelisk.

After encountering this transparent film of light, the plasma flow of particles with amazing lethality was like a water flow meeting a reef, and the particle flow directly split into two strands on the stele of the black obelisk, shooting towards the mountains and forests in the distance.

"The Heavenly Punishment Particle Plasma Cannon can't even penetrate the outermost defense of the Biological Gene Mutation Generator." Han Feng also took a deep breath after seeing the attack effect of the Heavenly Punishment Particle Plasma Cannon.

Ever since he learned that the biological gene mutation generator in front of him, the Calamity Angel-class battleship under the same medicine, belonged to the same civilization, he had some mental preparations.

But when he really discovered that the most powerful attack of the Unimog RV at the moment was powerless against a dead thing in the deep dark civilization, a deep sense of powerlessness still rose from his heart.
