Zhou Xuan has been soaking in the river for almost an hour, and the high temperature on his body has not subsided.

An hour ago, he ate the corpse of the mutant knife dog, and after that, the qi and blood in his body suddenly accelerated, the muscles and veins soared, the body temperature rose rapidly, and the energy hidden in the limbs and bones was ignited, and Zhou Xuan knew that after more than twenty days of accumulation, his body once again showed signs of evolution.

Zhou Xuan secretly rejoiced that this corpse was originally intended to be eaten by Xiao Manxue, because the energy of a mutant knife dog was enough for her to evolve from a beginner ability to an intermediate ability, and the overall strength of the two would be greatly improved.

But Xiao Manxue refused to eat this knife dog, because she really couldn't eat it anymore.

Zhou Xuan expressed his understanding, compared to him, the amount of food for a junior ability person is indeed not large, not to mention that a few hours ago, she had just evolved from an ordinary person to a primary ability person, and in such a short period of time, even if she was strangled to death, she would not be able to digest so much food.

Perhaps it was predestined that Zhou Xuan would break through the bottleneck at this moment and start the second evolution.

When he finished eating the corpse of the knife dog, the long-lost feeling of energy expansion reappeared, and Zhou Xuan was simply ecstatic.

He was chased by three mutant knife dogs just now, and he sighed that this evolution was too timely.

If he can evolve into a high-level ability at this time, monsters like mutant sword dogs and mutant blood corpses are not worth mentioning at all, and he can't even sense the smell on his body, this is a level advantage.

He and Xiao Manxue's rescue operation will also be much easier.

According to the memories of Zhou Xuan's previous life, the humans and animals who have just been infected have a mess of names, such as humans are called blood corpses, dogs are called knife dogs after infection, some people call them zombies, zombie dogs, and some people call them surviving, living dead, and reapers.

Different people have different names.

However, for their evolutionary system, the survivors of the world have a unified division.

Newly infected humans and animals are generally referred to as normal monsters, and they are the lowest level and weakest of the monsters. Ordinary monsters will begin to evolve after eating enough fresh flesh and blood, and those that have evolved once belong to the first-order mutant creatures, and the mutated blood corpses and mutant knife dogs belong to this category, and their physical strength, as well as strength and speed are equivalent to twice that of ordinary monsters.

Further up, the monsters that have evolved twice belong to the second-order mutant creatures, and their strength is twice that of the first-order mutant creatures, and this kind of monster is very rare in the early stage of the corpse tide outbreak, and it will not begin to increase until at least three months later.

And so on.,The more times you evolve, the higher the level of the monster.,The stronger the ability.,The highest-level monster that you've heard of in your previous life.,It's a fifth-order monster.。

He had only heard of this kind of monster, but he had not seen it with his own eyes, because anyone who had seen such a monster could not survive, they all died.

Why?

Among the survivors, there are also those who have evolved abilities!

Because, the strongest person Zhou Xuan had ever seen in his previous life was a biochemical warrior who had evolved four times, and he was far from being the opponent of a fifth-order monster.

You must know that whether it is a mutant monster or an ability warrior, every time it evolves, its strength increases exponentially, and the later it gets, the greater the difference in strength.

In the previous life, humans studied the secret of evolution a year after the outbreak of the virus, and at that time, first-order monsters were already everywhere, and many of them had evolved to the second and third orders, and even a very few had evolved to the fourth order.

The experts who studied this evolutionary method sold the secret to some large organizations at the time, and these large organizations did not spread the secret for their own selfish interests, but secretly cultivated capable people.

At this time, the vast majority of ordinary survivors were no longer able to compete with monsters, and only a very small number of capable people cultivated by major forces could barely fight.

But their numbers are too small, and they started late, how can they compete with the monster army that fills the world?

More and more surviving human beings have become food in the belly of monsters, and before they are reborn, there are only a few super-large gathering points left in the country that are still struggling to support, and other small and medium-sized strongholds have long since fallen, and the day of human demise is not far away.

If the experts who researched this secret in the first place chose to make it public to all mankind, or if the major forces that obtained this secret did not secretly harbor ghosts and cherish themselves, maybe mankind would not have come to this point, and maybe there would be a chance to recover the world.

It is the selfishness and greed of human beings that send themselves to the grave with their own hands.

After Zhou Xuan came back from rebirth, he actually had a plan to reveal this secret for a long time, not because of how noble he was, but because he wanted to create a better future for his relatives and friends.

If he wants to realize this dream, he alone will definitely not be able to do it, and all the survivors will need to work together. Even if you can't turn things around and recover the world in the end, you can at least create a safe, carefree home and let your relatives and friends spend the rest of their lives happily.

It's just that he later suffered the betrayal of his friends and lost the news of his relatives, these two things hit him hard, so he couldn't find a goal to live for a while.

Until I met Xiao Manxue.

This girl's persistence and strength infected him and rekindled his motivation to live.

In fact, Zhou Xuan came out this time, not only to help Xiao Manxue save people, he also had another more important plan.

Whether or not he can evolve to a high-level ability before taking action is the key to determining the success of his trip.

An intermediate-level ability can only barely deal with a single first-order monster, judging from the danger encountered on the road just now, if he encounters more than two first-order monsters at the same time, he can only flee in the wilderness.

Before entering the city now, I have encountered several first-order monsters, and when I enter the city, I will only encounter more, in case I am besieged by a few mutant monsters, it is difficult to protect myself alone, not to mention a Xiao Manxue.

But it's different if he becomes a high-level ability, and now that third-order monsters rarely appear, he can basically walk sideways, not to mention ordinary monsters, even first-order mutant monsters, it is estimated that it will be difficult to cause damage to his body.

Soaking in the cold river water, the circle that I figured out was not in a hurry, I was worried before, the strength of the monster will increase after dawn, and now I think about it, as long as he can complete this evolution, the strength of the monster growth is negligible.

However, Xiao Manxue was a little anxious, she soaked in the water for more than an hour, and it was almost 2 o'clock soon, they had not yet entered the city, and she was a little out of breath because she was worried about her sister's safety.

"Hey! Are you enough? How long will it take? Xiao Manxue touched the riverside and shouted at the circumference where only one head was exposed in the water.

The mobile phone he picked up just now was charging in the cabin, and Zhou Xuan couldn't answer, and he didn't want to answer, because he was now at a critical stage of evolution, and all his energy was spent on resisting the invasion of the virus into the nervous system, and he had no time to respond.

Thinking that the last time I easily completed the evolution in my sleep, I was a little distressed.

Maybe it was that night, the body had just been modified by the original virus, and it was lying in the freezer to dissipate the heat generated by the raging virus, so the subsequent evolution was almost a matter of course, and there was not much pain.

But this time it is different, the water in the Qingjiang River is indeed very cold, but it is far from catching up with the temperature in the freezer, and the heat dissipation effect must be worse.

And then there is the reason for evolution itself, the higher the level of evolution, the more heat generated by cell burning, if there is no good heat dissipation conditions, the final result is likely to be the evolutionary corpse poison into the brain, lose reason, and become a complete monster.

This is also the reason why there were very few high-level capable people in the previous life, because in the last days, only a very small number of large forces have mastered the technology of energy self-sufficiency such as hydropower, and they can use freezers and freezers to create conditions for the evolution of capable people.

Ordinary people can only use water to dissipate heat, which is very dangerous, because of the lack of conditions, many capable people are in the process of evolution, turned into blood corpses.

Since the second evolution, most people will no longer choose to use water to dissipate heat, and Zhou Xuan is forced to do so, there is no freezer in the cabin at all, and there are no other houses nearby, the corpse poison has already attacked, and he has no time to slowly look for the freezer.

Fortunately, the river is flowing, and his body has been tortured by the virus agent again, and his resistance has been greatly strengthened, so until now, he can still hold on to the last shred of his sanity and has not completely turned into a bloody corpse.

I don't know how long it took, but I was wandering on the verge of collapse, and finally felt the chill of the river.

Most of the heat in his body dissipated.

The tense nerves slowly relaxed, and he walked out of the water naked.

It felt like he had walked through the ghost gate, and he exhaled a long breath.

He is now sensual and acute, and he has a kind of martial arts novel written, seeing all directions and listening to all directions.

So as soon as he came ashore, he heard a soft sobbing sound behind the rocks not far away.

This faint cry sounded like thunder in his ears, which showed that his hearing was not trivial now.

"It's Xiao Manxue, I thought she left her alone."

The watch on Zhou's wrist was waterproof, so he could clearly see that the time was 4:45 a.m., and he had been in the water for nearly four hours.

Xiao Manxue actually waited for him for so long?

Seeing that it was about to dawn, she must have been extremely desperate to squat there crying alone.

Zhou Xuan felt a trace of guilt spreading in his heart, in fact, he couldn't blame him, the phone was out of battery at that time, and she couldn't see writing on the ground at night, Zhou Xuan couldn't explain his situation to her at that time, as soon as the corpse poison attacked, it was too late for him to protect himself, how could he still have the energy to take care of Xiao Manxue's mood.
