Zhang Xu also began to be bold, went to the 8th floor of the opposite building, just arrived at the 8th floor, a stench rushed in his face, Zhang Xu almost couldn't help but want to vomit, last time he left in a hurry, only to see that the door was open, and now Zhang Xu is a little bolder.

In fact, it is not impossible to go down quietly, but what if there are several zombies downstairs, when retreating, the zombies on the 8th floor rushed to block Zhang Xu's back when they heard the sound, so that the situation of the front and back attacks would be very dangerous, so Zhang Xu wanted to get rid of the zombies on the 8th floor to ensure that the back road was unimpeded.

Just when I looked at it, a male zombie with his upper body covered in dirty blood, with his back to Zhang Xu, was standing like a wooden man, motionless, but with a low roar in his mouth.

Golden opportunity! This zombie is facing away from Zhang Xu, Zhang Xu has a great chance to solve this zombie, the zombie after the corpse transformation is not fast, but the strength is greater, as long as you strike first, you can kill it.

Zhang Xu took a breath, closed his breath, sank his heart, and clenched the Tibetan knife in his hand.

Suddenly, the door was opened, and the knife slashed straight at the zombie's head, and the zombie fell to the ground before it could turn around.

Pulling out the Tibetan knife, dark black blood stained the blade, Zhang Xu gently closed the door, ready to search for supplies, just opened the bedroom door, and the change suddenly happened!

A female zombie pounced directly, opened her foul mouth and bit it, Zhang Xu didn't have time to react with his right hand, because Zhang Xu was wearing military tactical gloves, it prevented the zombie from biting, but it was still extremely painful

The zombie couldn't bite Zhang Xu, so he reached out and danced his claws, wanting to tear off a piece of meat, and the black nails were aimed directly at Zhang Xu's face.

Zhang Xu's left hand blocked, and with a light touch of his sharp claws, Zhang Xu's bloated fingers were immediately scratched, and bright red blood suddenly flowed out, and this zombie seemed to be even more excited, and its strength seemed to increase several times, and it opened its disgusting mouth to bite Zhang Xu's neck off.

Zhang Xu saw that he was scratched by zombies, and he couldn't avoid the result of becoming a zombie, and his heart was cold, but under the instinct of survival, Zhang Xu didn't want to be eaten by this ugly zombie, so he was ruthless in his heart, and he fought hard, but he was bitten anyway!

Because the zombie's strength was greater than Zhang Xu's, he directly knocked Zhang Xu to the ground, so Zhang Xu directly supported the zombie's head with his left hand.

Because this zombie is a woman, her arms are not as long as Zhang Xu's left arm, and the zombie waved her white arm but never caught Zhang Xu, but her teeth were so close that she wanted to bite off Zhang Xu's left hand, and the rancid mucus dripped out of its mouth and extended to Zhang Xu's chest, making Zhang Xu's stomach tumble for a while, and scolded: "What brand of toothpaste do you use, do you use toilet brand toothpaste?" Smoked labor to death...... Phew"

The five fingers clasped the zombie's face, because the zombie had already died, the muscle tissue had begun to die, and as soon as the finger poked the zombie's cheek, it was sunken in, and the skin was almost scratched off by Zhang Xu.

Enduring the pain of nausea, he picked up the Tibetan knife in his right hand and stabbed it directly into the zombie's brain, and the zombie who was still crazy stopped instantly.

Throwing the zombie aside, Zhang Xu gasped, and the blood flowed rapidly, he was suddenly relieved, and he sat on the sofa, waiting for death to come.

He knew very well that as long as he was scratched or bitten by a zombie for half an hour, he would definitely become a man-eating monster.

He simply didn't think about it, he was going to be finished, he knew that it was better to close the door, lock all the zombies into the house, and go downstairs directly.

If it weren't for the fear that the sound of locking the door would attract the zombies in the house, the zombies would definitely hit the door, so that there would be a sound, which would definitely increase the danger of Zhang Xu going downstairs.

"I'll probably never see you again, Zhinuo." Zhang Xu glanced at the quantum instrument on his wrist and thought of Xuan Zhinuo.

"Dad, Mom, my son may never be filial to you in the future." Zhang Xu closed his eyes and sighed.

"If I have an afterlife, I will definitely live well. Haha, friends, goodbye!" Now Zhang Xu has reached the point of fever.

"Xiao An, if I become a zombie in the future, you can find another master." Zhang Xu said to the quantum instrument, but the quantum instrument did not reply, and gently sucked a drop of blood on Zhang Xu's wrist, but Zhang Xu, who was in unbearable pain, couldn't feel it.

Zhang Xu also wondered why he didn't speak when he was dying, and simply ignored the quantum instrument.

For about 20 minutes, Zhang Xu's cheeks were covered with beads of sweat, ordinary fever would feel very cold, and the lack of fever on his body was the opposite, but the fever infected by zombies was the opposite, Zhang Xu felt like a fire, sweeping all over his body, but his body was amazingly cold.

Zhang Xu roared angrily, the intense burning sensation made Zhang Xu unbearable, and he could only rely on yelling to relieve the pain, the cold blood seemed to freeze Zhang Xu's throat, making him unable to make a sound, and the blood vessels in his body were frozen purple, which was particularly obvious under the skin.

In nature, natural selection, survival of the fittest, no creature survives by luck, but all by their own hard work, in order to have a place in the biosphere.

Giraffes were originally just a common population, because of the shortage of food caused by environmental troubles again and again, the young grass on the ground has long withered, are these giraffes not young grass to eat to give up their lives, no! They chose to evolve, to evolve their necks, so that they could eat the shoots of the trees, so that they could adapt to the environment at that time.

In the Jurassic era, why dinosaurs could dominate the earth but perished because of the environment, because they would not evolve, I don't know why, plants began to decrease a lot, oxygen content decreased, herbivores decreased suddenly, and the huge bodies of dinosaurs could not adapt, but weak races survived, such as small lizards, but they could survive with enough food.

On the contrary, if you want to survive, you can only adapt to the environment, not want the environment to adapt to you, let alone try to avoid the difficulties brought by the environment.

Just like this society, don't try to change it, just try to adapt to it, otherwise you will only be eliminated.

And zombies may also be the difference in human evolution, human beings have always been the top hunters of the biosphere, no matter what creatures can not resist the domination of human beings, destroy the natural environment, but the appearance of zombies has changed, zombies feed on humans, is it a disaster given to human beings by nature?

Therefore, human beings must gradually learn to evolve in this disaster, and if they do not evolve, they will only be eliminated by zombies and become the rations of zombies.

It is said that all cells evolved from the first hematopoietic stem cells, and the different structures of DNA have led to the diversification of cell structures.

Zhang Xu's bluish purple whole body instantly turned red, and Zhang Xu felt that it was no longer scorching, but an unforgettable cold.

At this moment, Zhang Xu's blood was all like boiling water, his skin turned red from blood, and the blood all over his body was churning, gritting his teeth, Zhang Xu, who was bruised in his muscles, struggled to resist the pain, and the blood vessels drilled into Zhang Xu's blood vessels like poisonous snakes and expanded.

And the bones in Zhang Xu's body are constantly evolving by an unknown cell, making a clicking sound, but Zhang Xu has no feeling at all under the cold.

Gradually, the spine behind Zhang Xu slowly changed...

After almost a few minutes...

At this time, Zhang Xu was already in a coma, and he passed out in pain, if Zhang Xu vomited blood after having a fever again, it means that the virus has completely conquered the central nervous system of Zhang Xu's brain.

10 minutes, 20 minutes...

Zhang Xu is still unconscious, but he has never turned into a zombie.
