After the evolutionary reaches the five-star, the body's immunity is stronger, and it can already take the initiative to repair the damaged body, such as lumbar muscle strain, lumbar disc herniation and other labor injuries, as well as myopia, these incurable diseases, can be automatically recovered.

In addition, diseases such as albinism, diabetes, congenital heart disease, cleft lip and other genetic defects will slowly disappear and return to normal as the evolutionary body.

Five-star evolutionaries have the ability to repair automatically, and although the immune system is destroyed after being infected with AIDS, they can also slowly repair the immune system and recover completely, even the extremely powerful Ebola virus cannot kill the five-star evolutionary.

Ebola virus is a very powerful virus known to mankind, this virus has a mortality rate of about 80%, and it is terrifyingly contagious, it can be transmitted without physical contact, and can be transmitted through the air, which is very similar to the cold virus.

The mortality rate of 80 percent sounds like a no-brainer, but in fact it is already very terrifying, and even the outbreak of the SARS virus in China that year was only half of the Ebola virus.

Smallpox, anthrax, cholera, and plague, all of which numb the scalp from plague viruses, have a mortality rate of less than 50 percent with current technology, among which the plague was the Black Death that killed half of the population in medieval Europe.

In ancient times, although the mortality rate of these viruses reached 70 or 80 percent, it was because of the limited level of medical care, at that time the medical treatment in Europe was very backward, the sanitary conditions were extremely poor, and the disease was basically bloodletting treatment, which was very simple, and there was no Western medicine level at all.

If the Ebola virus had been treated with the same level of medical care in ancient times, the mortality rate would have been almost 100 percent.

Some countries once fantasized about creating a super virus that could wipe out the whole world, and the blueprint of this super virus was the Ebola virus, which shows the strength of the Ebola virus.

The reason why the Ebola virus has not become a global plague, but only a regional plague, is not that its infectivity and mortality rate are not high, but that the onset of the disease is too fast, at most a week, or even a few days, the capillaries of the whole body will rupture, and the body will bleed and die of hemorrhage.

With such a rapid onset time, the carrier will become ill before it has time to infect others, thus attracting the attention of other people and avoiding being infected.

If the Ebola virus, like AIDS, has an incubation period of several years, or even more than ten years, then this virus can completely destroy mankind, and even if it cannot completely destroy mankind, it will become the most terrifying disaster in human history.

In addition to attacking the human immune system, there is also a very important reason for the horror of HIV, which is the long incubation period, and many people infected with AIDS do not know that they are infected, because the body is exactly the same as before, thus becoming a dangerous transmission agent.

This is also why the state has always advocated caring for AIDS patients, because once the society completely abandons AIDS patients and completely discriminates against them, these AIDS patients will have the idea of revenge against the society, which is completely impossible to prevent, because HIV carriers are exactly the same as ordinary people, and they cannot be screened at all.

If the evolutionary evolves one step further and reaches an eight-star or even nine-star evolutionary, then the optimization of genes is almost perfect, and all the defects in the genes have been repaired, and they are already considered flawless human beings in the true sense.

This flawlessness is not just about appearance, but also flawless on a genetic level.

Evolvers who have reached this level will hardly get sick, and even if they inject a high concentration of HIV into their body, these viruses will be destroyed by powerful bodily functions the moment they enter his body.

Moreover, such evolutionaries will not die from radiation if they are placed in areas with high radiation, let alone get cancer because of radiation, because there are no carcinogenic factors in the body.

The reason why human cancer is because there is a defect in the gene, this defect is generally not manifested, but when it is stimulated by external stimuli, such as radiation, formaldehyde, etc., it will revive and produce cancer cells, which will continue to divide and replicate, becoming malignant tumors, and eventually leading to cancer.

Therefore, why cancer also has a certain hereditary nature.

As the strength of the evolver continues to improve, the genes continue to be optimized, the genes are becoming more and more stable, more and more powerful, and the exclusivity is getting stronger and stronger, especially when it reaches the nine-star level, the injection of phagocytic genes, the moment it is injected into the body, it will confront the powerful body functions.

The body will reject any foreign body, and subconsciously think that it is an invader, resulting in a fierce confrontation, and the result of the confrontation is to cause the genetic collapse of the nine-star powerhouse and finally die.

Or a strong bodily function to eliminate the phagocytic gene, which is equivalent to not injecting the phagocytic gene.

"Now that I'm just a one-star evolutionary, and the degree of genetic optimization is very low, it should be the best time to inject the phagocytic gene." Ye Feng looked at the DNA syringe in his hand and muttered.

During this period of time, hunting zombies in the Agricultural University, among them, he also obtained several crystal nuclei of second-order zombies, and after obtaining the crystal nucleus of second-order zombies before, the second-order crystal nucleus in Ye Feng's hand could barely extract a two-star evolution liquid.

Ye Feng's strength has improved during this period of time, and his life intensity has been close to 3 times that of ordinary people, that is, he has reached the peak level of a one-star evolution, as long as he has a two-star evolution liquid, he is very likely to become a two-star evolutionary.

However, Ye Feng did not use the second-order crystal nucleus to extract the evolution liquid, because he was hesitating whether to fuse the devouring gene at the time of the first star.

"Forget it, the time to come will come!" Ye Feng took a deep breath, and the hesitation on his face subsided, replaced by a resolute color.

Ye Feng clenched the DNA syringe, and had already made a decision in his heart, preparing to fuse the devouring gene at the time of the first star, the further back he dragged it, the more stable the gene was, and the more difficult it was to fuse.

Ye Feng figured it out, the key to his hesitation was that he didn't know the chance of successful fusion, he was afraid that the fusion would fail and his body would be controlled by the devouring genes, after all, Ye Feng had just come to this universe, and he knew a lot of future trends, if nothing else, he would definitely stand at the top of evolution.

However, even if Ye Feng stood at the top of evolution and became the most powerful handful of evolutionaries of human beings, he could not change the general trend after all, and human beings were still not the opponents of zombies, mutant beasts, and world-destroying monsters, and they retreated into one base after another, and finally gave up the earth.

Therefore, Ye Feng figured it out, if he didn't inject the devouring gene, he would live for more than twenty years, and then in the final war of mankind, he would be killed by the Corpse Emperor or a high-level mutant beast, or he would be eaten by a certain world-destroying monster.

It's better to gamble with your life now, failure is equivalent to living less than 20 years, and success may be able to fight for a future and achieve a new era.
