The work of relocation of the base was finally over. The Tigers took far more time and energy to finally complete this task. It has to be said that the zombies who started using tools were more difficult to deal with than before.

The situation became increasingly serious. Although the base had notified several survivor camps that had established communications with the base with the latest information on zombies, it was obvious that these people did not pay enough attention to this situation. Soon, the camps sent a series of distress signals, asking the base to send people to help find the whereabouts of their field staff.

In the conference room, the members of the Tiger Team who were ready to go had just finished listening to the mission briefing, but Dr. Mei rushed in.

"Sit back for me." Dr. Mei said in an unquestionable tone: "None of you is allowed to set out before I finish speaking!"

After the human body is attacked by zombies, the z-type enzyme enters the human body's blood circulation system along the wound. The white blood cells in the human body shoulder many important tasks, one of which is to swallow foreign objects and produce antibodies.

After the type enzyme enters the human body, the white blood cells will desperately swallow the invader, and then be infected by the z-enzyme and produce more z-enzymes. Therefore, the human body begins to experience zombie symptoms such as high fever and convulsions. Until the z-enzyme completely defeats the white blood cells and gains control of the human brain, the infected person will die.

Then, the z-type enzyme began to resurrect the dead. Of course, this is not a real resurrection. First, the brain part, the z-type enzyme only controls a small part of the human brain, and a large part of it belongs to areas that humans themselves have not developed. From this point of view, zombies should only have the most basic animal instincts. Secondly, the human body is a complex machine, and cells will die after hypoxia. The blood in the zombie body obviously does not have the function of carrying and transporting oxygen. The rotten smell emitted from the zombies can well prove this.

The reason why zombies can maintain this semi-corrupt state is also the effect of this enzyme. The corrupted bacteria attach to the zombie's body, providing a continuous stream of energy for the z-type enzyme. This is why zombies will not eventually turn into a pool of stinky water over time or end up starving to death because there is not enough food.

There is reason to believe that zombies themselves do not need any food to live for immortality, as long as the z-type enzymes are always present in the zombie's body. Mei Qiu and her medical team have also conducted a lot of research on zombie feeding.

The brain scan results of zombies show that when zombies find the target, a mysterious area of ​​their brain will begin to enter an abnormally active state. This area will not calm down until the target disappears for a long time, while the area in the brain responsible for hunger signals does not react at all.

Many people become zombies after being bitten. Judging from the information feedback from the Tiger Team's outing, they have never found any corpse that has been completely eaten up. This can also prove Mei Qiu's judgment from one aspect.

If zombies attack humans only because of the most primitive demand for food, then when a living person is surrounded by a group of zombies and eaten separately, what is left may be a pile of dead bones, not a new zombie. Therefore, the purpose of zombies attacking humans is likely to have nothing to do with the food that people originally expected. According to the data analysis, Mei Qiu made his own judgment.

The predation of zombies is better to release the z-type enzymes in the body. Whenever the staff appears in front of the experiment, the experiment will always secrete a large amount of saliva containing the z-type enzymes and enter a violent and aggressive state, but when the experiment is alone, this situation will hardly happen.

Research on zombie evolution, thanks to the corpse of the crusher brought back by the Tiger Squad, Mei Qiu was able to compare the ordinary zombies with the evolved zombies. The results show that the z-type enzymes in the crusher and the ordinary zombies are no different, but the DNA structure between the two is very different.

The smasher has more genomes on the DNA chain, and these gene sequences seem to come from different individuals. This situation is impossible in normal people. The only explanation is that the smasher obtains these gene fragments through other channels.

In order to verify this observation, Mei Qiu made a bold attempt: feeding. After the zombies bite humans, the human blood and muscle tissue will enter the zombie's body through the digestive tract, which is likely to be the way for zombies to obtain other genetic fragments.

Mei Qiu dripped his blood into the mouth of the experimental subject to observe whether the zombies really evolved by obtaining gene fragments in this way.

Unfortunately, Mei Qiu's experiment did not make much progress. The DNA in the experimental body cells did obtain new gene fragments. But I don't know if it was because the time was too short or too little genetic material was obtained. From the surface, the experimental body was not changed. This is very different from the previous expected result - evolution.

As the only individual who was not zombie-like after being attacked by zombies, Zhao Qiang is also a key research object for Mei Qiu. During the battle in Yuelu Mountain, Zhao Qiang was injured by the sharp teeth of the zombie rat, and then he developed a very serious zombie-like phenomenon. He was unconscious, had a high fever and had his limbs twitching.

When everyone thought they would lose Zhao Qiang, a miracle actually happened, and this situation greatly aroused Mei Qiu's interest. In her opinion, there must be some special antibody in Zhao Qiang's body to resist the infection of the z-type enzyme. As long as this substance is extracted into a vaccine, people will usher in the dawn of victory.

After analyzing Zhao Qiang's blood, Mei Qiu found that not only Zhao Qiang, but all the human blood in the base contain a special protease - n-type enzyme. Its molecular structure is very similar to that of z-type enzymes, but its existence can neutralize the transmission of z-type enzymes in the human body.

Unfortunately, the activity of n-type enzymes is much lower than that of z-type enzymes. They have always been out of a disadvantage in their fight against z-type enzymes. Once a person is bitten by a zombie, a large amount of saliva containing z-type enzymes enters the human body along the wound, and then everything is over.
