When everyone heard this, they were all shocked.

Although Su Ziyan's explanation is unique, if you think about it carefully, it is not unreasonable.

"If that's the case, does it mean that zombies can continue to evolve?" Hou Xunwen listened to it for a long time, and he didn't know how to explain it in detail, but he understood the reason.

"If zombies are also creatures, creatures have the potential to evolve!"

Su Ziyan said in a flat tone.

Pigs, dogs, cows, sheep, humans, and even zombies all have the potential to evolve. It's just that the evolution of the first few lasted millions or tens of millions of years, and the zombies were the "protagonists" who participated temporarily, standing directly on the shoulders of their predecessors to look at the world.

Su Ziyan doesn't believe in the truth of making something out of nothing, so she thinks that the beginning of all things must have its own reasons.

For example, there may be some explanation for her abilities that have not yet been explored by human science.

If the zombie is regarded as an independent creature, then the outbreak of the zombie apocalypse is tantamount to a strong invasion of alien species, which has brought a devastating blow to the original ecosystem.

Of course, Su Ziyan can't prove whether her guess is correct, but out of instinct, she thinks that this possibility is still quite large.

Zhang Xiaojing saw her talking eloquently, with a little surprise in her eyes, thoughtful.

Jiang Yan was silent for a while, then suddenly raised his hand and said: "Then if it is said that the human central nervous system is too complex and the reaction after the virus invasion is too violent and destroys the nervous system, then what about relatively low-level creatures?" Can their transformation be completed, and why haven't we seen even a shadow of them until now? ”

"I don't know."

Su Ziyan looked at Jiang Yan and shook her head: "I don't know what will happen to other creatures after they are invaded by the zombie virus, but we might as well think about it from the perspective of human beings themselves." ”

Jiang Yan, Su Junwu, and Hou Xunwen all pricked up their ears.

From the perspective of human beings, how should we understand it?

Su Ziyan glanced at them and said, "Human beings are the primates of earth creatures, and they can be said to be the most thoroughly evolved creatures!" However, when the zombie virus came, there was still a very obvious group differentiation among us! ”

"Some people resisted the invasion of the virus when the first wave of viruses hit, let's assume that the zombie virus is the same as other virulent viruses, then people with strong ability to resist external viruses naturally produce corresponding antibodies against them when a small number of viruses invade the body!"

"There are not a few such people, and from current experience, more than ninety percent of people have this ability to resist!"

Jiang Yan frowned, blinked and said, "This probability seems to be a bit high, even higher than those fierce flu viruses!" ”

Zhang Xiaojing also agreed, feeling that the infection rate of the zombie virus is somewhat low.

"Yes!" Su Ziyan nodded, "The success rate of the human body in intercepting the virus in the first time is as high as more than ninety percent, which shows that the zombie virus in the early stage is actually very weak!" The common flu virus can also cause people to have uncomfortable symptoms, but after being infected with the zombie virus, many people have no symptoms at all. ”

"Of course, this may have something to do with the specificity of the virus, or maybe it itself has no external symptoms."

Su Ziyan first ruled out the special situation of uneven distribution of the virus, which leads to different degrees of infection of people, because the outbreak of the zombie virus is wide-area, and the scope of the spread is extremely wide, so there will be no uneven distribution. Its infection is more like it is only related to the physical fitness of the individual human being.

"And those who failed to produce antibodies in time and successfully resisted when the first wave of zombie viruses came unfortunately became the first wave of mutant zombies! At this time, the zombie virus rapidly erodes their nervous system and combines with the body, resulting in the so-called 'evolution' of the body. ”

"This is the wrong evolutionary direction!" Jiang Yan exclaimed.

"That's right, that's wrong in our opinion." Su Junwu said in horror.

Su Ziyan nodded: "These infected people failed to clear the virus in the first place, so that the virus broke through the immune defense and spread rapidly and eventually turned into zombies!" The number of viruses in the bodies of these mutant zombies will increase across the board, which is based on the judgment of general virus reproduction, and I suspect that these viruses may have undergone directional evolution and become more adapted to the human species. So the next people who were bitten by zombies, on the one hand, injected a number of viruses far beyond the scale of the first wave, and on the other hand, these viruses were also more targeted, so mutating into zombies was inevitable. ”

Those who resist in the first wave of virus invasion are equivalent to having a certain amount of immunity, but they can't resist the invasion of more and mutated viruses!

If you are bitten by a zombie, not to mention that the bite itself is fatal, even the huge number of viruses is enough to kill the bitten.

The reason why zombies are so aggressive, Su Ziyan suspects that it may be related to the evolutionary trend of the species, and these viruses also have the instinct to spread more and more widely......

"Then Sister Ziyan, how can an evolutionary like you explain it?"

Jiang Yan thought about it and digested the information he had obtained before, but he still had doubts about the appearance of the evolutionary in his heart.

"That's based on my judgment that the zombie virus is evolutionary." Su Ziyan's beautiful face showed a smile, and then she said coldly: "In the first wave of virus infection, one percent of people have turned into zombies, and ninety percent of people have nothing to do, but there should still be a special individual who has neither become zombies nor completely killed the virus." ”

"Maybe their physique is particularly well adapted to the virus, so the virus did not cause their mutation after being infected in the first place, but smoothly combined and completed the evolution of the individual!"

Evolution is a slow process, a process in which external factors enter the body and violently destroy the original meticulous system, so that the infected in the evolutionary stage will fall into a coma and high fever. If the body can successfully persevere, it will wake up as an evolutionary, but if it can't persevere, it will either die due to the collapse of the original system, or it will become a zombie.

"In a way, the Evolver is on the same level as the Bright White Zombie, both based on an evolution made by an individual human! It's just that the evolutionary is based on the original system, and the zombie with bright white eyes is the evolution that has come out of the wrong evolutionary path! ”

Su Ziyan's voice was a little low, and anyone who knew that they were the same "product" as the bright white-eyed zombie would not be in a good mood. Su Ziyan rejected this kind of speculation, but with the repeated deduction in the past few days, she found that this possibility may be real, and it is a high probability event!

Jiang Yan, Su Junwu, and Zhang Xiaojing gasped, looking at the woman in front of them who looked bad, but was extremely beautiful, they really couldn't connect with the "zombies".

But after thinking about it, I feel that this is not the case!

Su Ziyan's evolution is a normal evolution with humans as the main body after being infected with the zombie virus, while the zombies with bright white eyes are an evolution that causes the body to change after the virus erodes the human body, and then is dominated by the virus.

The mechanism of the two is similar, but the direction and dominance of evolution are far from each other, and they can be said to be natural enemies.

Taking a deep breath, Su Ziyan's expression returned to normal, and she continued with a light smile: "From several circumstances of human beings, it is not difficult to find that it is precisely because the evolution of the human central nervous system is too complex that the possibility of zombies appears, but at the same time, because of the resistance of human individuals, the zombie virus cannot infect the vast majority of people. ”

"So I guess...... Relatively low-level organisms, they are unlikely to successfully resist the infection of the zombie virus, and even a considerable number of species will cause the complete collapse of their fragile systems and complete extinction due to the infection of the virus, but at the same time, the possibility of the zombie virus successfully causing the species to complete the correct evolution is also much greater......"
