The emergence of large-scale biological mutations has brought the world situation that had been gradually stabilized into turmoil again.

Humanity had already thought that its enemies were the ugly zombies, and had gathered strength in various survivor bases, ready to retake the territory and rebuild their homeland.

Just like when zombies appeared, all kinds of strange creatures suddenly appeared, making many survivor bases pay a heavy price.

Not long after Yi Xuan snatched the biological specimens from Gong Shao's troops, a terrifying marine creature attack occurred at a superbase off the western coast of the United States, causing an uproar on the Internet for a while.

At this time, nearly two months had passed since Yi Xuan got the biological specimen.

The researchers in the cave conducted a thorough analysis of the biological specimen and came to the conclusion that the specimen's genetic profile was 99% similar to that of an earthworm.

In fact, there are still so many gene structures, not more or less, the only difference with earthworms is that the recessive genes in the past period of the gene sequence have undergone amazing changes, not only dominant, but also subversive changes in the entire map.

According to the answer given to Yi Xuan by those biologists, this earthworm has undergone atavism, and the return is very exaggerated.

It's just that why this phenomenon is caused, it has not yet been concluded.

However, all kinds of speculations and arguments have made the researchers in the cave almost noisy.

You must know that the scientific researchers who can enter the cave are all carefully selected by Yi Xuan and screened layer by layer.

Even in times of peace, he is the world's top talent and in every country.

If this disaster hadn't come too suddenly, Yi Xuan wouldn't have had a chance to let these people work under him.

However, because of this, after obtaining the specimen and starting the study, different opinions and arguments also broke out.

For a while, in the biological research forum in the cave, the first fierce debate broke out.

But these are all within the scope of control, and this is what Yi Xuan wants to see.

As the so-called truth becomes clearer and clearer, although the real answer has not yet been reached, this kind of active scientific research atmosphere is what Yi Xuan has always wanted, and it has completely made the scientists who have been a little lifeless since the outbreak of the disaster find their life goals.

But in any case, everyone agrees that earthworms have atavistic phenomena, but it is not known whether this is an isolated case or a large scale.

If it was in the past peaceful era, everyone thought that this was an individual case, and after the outbreak of the zombie virus, although whether in the world or here in Yixuan, the special drug to resist the virus has not yet been developed, but everyone has a very clear understanding of the genetic situation of the virus, and it is actually caused by the atavism of several viruses.

The virus is atavistic and who will believe it when it comes out? Generally, viruses will gradually evolve and mutate, and the atavistic ancient virus will be even more powerful?

And the thing is so strange, the zombie virus is the atavism phenomenon at the genetic level after the combination of several viruses that have been common in humans.

The ancient genes in these viruses have mutated from recessive to dominant, and they have absorbed all the ancient genes from each other to form this new type of virus.

And for this situation, for the time being, human beings really don't have much to suppress.

And the most terrifying thing is that because the ancient genes have a more powerful evolutionary ability, so far, in the research room of the cave, the specimen with the most mutations of this virus has undergone 5 mutations.

This shows that so far it can be considered that there have been 5 mutations of zombies in the zombie group, but in the wild natural environment, there are so many zombies in the world, how many mutations have occurred, then only God knows.

However, one thing is for sure, the Wolf Warrior Team has encountered many strange zombies on the outside, with different abilities, but it still causes some trouble to the Wolf Warriors wearing individual armor.

This is in stark contrast to the situation when the disaster first broke out, when the wolf warrior team was invincible and could slaughter zombies at will.

It shows that with the further mutation of zombies, it will no longer be as easy to deal with as before.

The only consolation is that the mutation is not as fast as feared, and the speed is greatly reduced.

This can be seen from the fact that the virus specimen of the fifth mutation in the Dongtian laboratory has not mutated, and this kind of powerful evolution is not so easy to happen.

It's just that Yi Xuan didn't really feel at ease, especially after every time he went out and couldn't see the cats and dogs that he usually saw everywhere, this worry became more and more obvious.

After the outbreak of this marine life attack on the west coast of the United States, Yi Xuan immediately sent a wolf warrior team to investigate there.

And the information he got made Yi Xuan's worries come true, the atavism of creatures really happened on a large scale, and the fastest thing that happened was the sea creatures.

The ocean is the birthplace of life, and many of the five species in it are close relatives of the progenitors of terrestrial life.

So at the genetic level, their genes are even older, and mutations naturally occur first.

Although almost 1 day has passed since the incident, the photos and videos taken by the wolf warrior team can still show the fierceness of the battle.

Perhaps because zombies don't come in from the water, this superbase complex on the west coast of the United States doesn't have any high walls in the direction of the sea.

Therefore, most of the buildings near the sea still retain the appearance of pre-disaster resorts.

It's just that at this time, Yi Xuan saw that it was indeed an apocalyptic scene, all kinds of seaside villas and small buildings were destroyed, and the ruins could describe the current scene, which was even more terrifying than the city that had been invaded by zombies, and none of the buildings could still see the original appearance.

The streets and beaches were littered with blood and corpses, as well as the corpses of creatures that were either charred or bloody.

However, these corpses were without exception huge in size, and several corpses were piled up there like a small mountain, which reminded Yi Xuan of the earthworm mutant he had seen.

It can be seen that after paying a lot of casualties, this super base has withdrawn from here, and even the corpses all over the ground have not had time to deal with it.

After selecting some specimens of the corpses of sea creatures, the Wolf Warrior Team returned to the cave without staying any longer according to Yi Xuan's order.

Now the specimens have been handed over to the biologists of the cave for identification, and the results will take about a week to reach a conclusion.

At this time, Yi Xuan's heart had already estimated that it would be similar to the atavistic earthworm.

It seems that he really underestimated the zombie virus made by the Syndicate.

What was thought to be a simple virus now appears to have a serious impact on the entire planet's biosphere.

In the past, Yi Xuan was also glad that this virus was simply infecting humans, and it had no impact on other creatures.

After all, I haven't seen any zombie creatures so far, but I never thought that this virus could not infect people, but these creatures can change the genes of creatures.

It's just that this change doesn't spread as fast as the zombie virus, so much so that humans ignore the rest of the creatures while dealing with zombies.

And now, after more than a year of development and diffusion, this change has really reached the time of a large-scale explosion, so that humanity has no preparation at all.

Now it seems to be just an attack, and Yi Xuan estimates that there will be more and more such attacks.

The human race, which had just stabilized to deal with the zombie attack, was once again added with a large number of new enemies, and the survival of the human race was even more challenged.

It's just that this time the human race has formed one base after another, and after uniting together and being impacted, it will not be as powerless to fight back as it was after the outbreak of the zombie virus.

However, the living space of human beings will inevitably be further compressed, and they will completely fall from the position of ruler on this planet.

And Yi Xuan felt that the matter was not over yet, human beings had mutated, ordinary creatures had mutated, so would plants mutate.

The answer is obviously yes, after all, the most intuitive thing is that the crops grown by humans have now changed, and it is really impossible to predict what will happen to more of the rest of the wild plants.

The survival of mankind is becoming more and more difficult, and it seems that their own plans have to be hurried.

And just when Yi Xuan was thinking about the countermeasures for large-scale mutation of organisms, because of a sudden discovery, Yu'er found Yi Xuan.

"You're saying that Tuan Tuan and Yuanyuan's special abilities aren't innate?" Yi Xuan asked in surprise.

From bringing Tuan Tuan and Yuanyuan back, Yi Xuan handed them over to Zheng Xiuji, asked their sisters to take care of the lovely siblings, and at the same time asked Yu'er to test them and figure out what was going on with their special abilities.

"Right!" Yu'er said with some excitement: "Do you remember the purpose of the action when you found Tuan Tuan and Yuanyuan?" ”

Yi Xuan nodded and recalled: "Of course I remember, it was more than half a year ago, you said that you found the energy fluctuations of the magic weapon on the earth, let me lead the team over to take a look." And that's where we met Tuan Tuan and Yuanyuan. ”

"But we don't know anything strange!" Yi Xuan continued: "Could it be that you found it?" ”

"Of course!" Yu'er was a little stinky and stinky: "Don't you see who I am?" I think of the famous ...... in the fairy world back then"

"Alright, alright! Don't brag there, tell me what the hell is going on! Yi Xuan held his forehead and felt that he had been defeated by this guy, and he had to brag about himself every time.

How many times has this been, Yi Xuan felt a little like vomiting.
