Iron's laughter grew even more arrogant, but his unbridled laughter soon attracted the attention of the giant mutant zombies.

Mutant zombies can sense each other's level of strength and weakness, and at the same time, mutant zombies can also have a clear sense of the evolved cells of the evolutionary, which is more vigorous than the average survivor's vitality, and has a huge attraction to mutant zombies, which is very suitable as a tonic after injury.

Crazy Iron's body continued to change, and a sharp blade resembling a fish fin grew on his back, which was able to increase his speed to a certain extent.

After rushing to the side of the giant mutant zombie, Crazy Iron slashed at the mutant zombie's knee with his giant blade-like arm.

Roar!!!

The giant mutant zombie roared angrily, and its big hand grabbed directly at Crazy Iron.

However, Crazy Iron stretched out his arms and spun rapidly in place, like a spinning top spinning at high speed, flexibly spinning to the side to avoid the attack of the mutated zombies.

Crazy Iron's blade and arms slashed at the body of an ordinary zombie, it is really like chopping melons and vegetables, as long as it touches that zombie, it will definitely be cut into two parts, and the sharpness and toughness of the blade transformed by the ability can be initially compared with the mutated zombie to the dark matter.

The so-called dark matter is a name for those evolutionaries in Evolution City, and after fighting more mutant zombies, they have recently had some positioning for mutant zombies.

Mutant zombies with dark materialized bodies belong to mutant zombies with great room for growth, and usually have a serious enough attitude towards this kind of zombie evolution.

There is also a biological laboratory in the City of Evolution, where the researchers are not well-known domain experts like Lin Zhongwei, they are monsters hidden in the dark! It's crazy!

These people once had the opportunity to become top experts in the field of genetic biology, but because these people were too obsessed with the exploration of the secrets of life, their ideas and research directions were relatively bold and crazy, and they had already involved some areas that were strictly forbidden by the industry.

A formal biological laboratory requires a lot of formal and complicated processes for experiments involving human beings.

In an underground laboratory, in addition to a small number of people who are tested for money, more people are test subjects who have been arrested by illegal means, and these people usually die because of crazy experiments, infected with various rare diseases, and more die tragically on the spot.

These experiments include fusing and modifying human and animal genes, studying viruses, and of course, sometimes selling organs for research funding.

In short, these researchers in the dark, compared to money and reputation, they pay more attention to the results of a research, and their obsession with experiments makes them make crazy decisions one after another, for which they can do whatever it takes, they can give up human ethics, and they only have continuous exploration in their eyes, and there is no end to it......

However, there is one thing that cannot be ignored, geniuses are crazy, or it can be said that only crazy people can become geniuses! Putting aside many constraints and rules, these madmen are often able to study more and explore the secrets of mankind relatively more.

Once these people succeed and make a huge breakthrough in one field, no matter how dark and dirty his past is, as long as he is needed, his past will become a life model for all aspiring young people.

And in the city of evolution, there are such madmen, these madmen are just madmen before the end of the world, crazy people who can't see the light, and in the last days, they are out-and-out geniuses, and their research is increasing the survival chances of human survivors little by little, and is changing humanity!

Different from the progress of the security zone, the researchers in the biological laboratory in the city of evolution, they are more thorough in the study of zombies, they not only use the blood of survivors to study antivenom, but even boldly use zombie blood to study antivenom serum, and personally make survivors into zombies, and then make the best use of zombies for dismemberment and more in-depth research.

Now the city of evolution has produced the first batch of antivenom, people who are attacked by zombies inject this antivenom within an hour, there is a sixty percent chance that they can successfully resist the virus, but the other forty percent will directly become zombies. Second Chinese Network

Not only that, but as early as the emergence of evolutionary beings, these people had already begun to study artificial evolutionaries and purify the evolutionary energy in the evolutionary crystal.

Their current technology only requires three evolution crystals to purify an evolution potion, which is far ahead of the technology in the safe zone!

And in terms of artificial evolutionists, Evolution City also has some huge breakthroughs, which are roughly divided into two directions.

Evolvers with normal cell evolution, their physique will only awaken and start evolution after reaching a standard value, which is difficult to do in artificial research, so if you want to become an evolutionary, you can only find another way!

Lin Zhongwei's research is based on the Evolution Beast, whether it is the antivenom or the awakening potion that he is about to start to accelerate the evolution of the elixir, he follows the principle of the least risk, the lowest side effects, and the steady progression.

And the researchers of Evolution City, their direction is bolder, they only need one to become an evolutionary, or it can be said to be the result of becoming stronger, as for the process and sacrifice, they don't care at all.

At present, the research of artificial evolutionists is divided into two directions by them, conventional cell evolution and physical mutation enhancement, the so-called conventional cell evolution, which is to use the blood of evolutionary beasts or even evolutionaries to do research to unlock the human biological code.

The direction of body mutation enhancement is to boldly fuse the zombie virus of mutated zombies, which is a wrong path chosen for some survivors who cannot evolve!

This kind of research seems simple and complex, and it needs to be based on some small results of conventional evolution, and its principle is to make people become half-corpses, with a certain degree of mutated zombie ability, but still be able to maintain the normal thinking logic and way of thinking of human beings.

So far, Evolution City has only mastered this technique in the first place, but the success rate is extremely low, only one person out of every thirty people can succeed, and once it fails, the person injected with the serum will completely turn into a zombie.

And those who are lucky enough to succeed, their aura will be between humans and zombies, which allows them to walk through the zombie group without being attacked, and only mutated zombies can tell the difference between them.

People who are usually stronger in a situation cannot be called Evolvers, and the people of Evolution City prefer to call them Corpses!

Corpses don't have the ability to change like evolutionaries, and most of the corpses are based on strengthening the characteristics of their bodies, and they have the characteristics of zombies, that is, they won't die without being shot in the head, and they can repair their bodies by eating fresh flesh and blood if they suffer serious injuries.

Unfortunately, there is very little fresh flesh and blood in this last days, so there are only two choices left, cannibalize the same kind, or eat zombie carrion.

No matter which one of them you choose, as long as you choose one of these paths, after you go down, the corpse will become more and more detached from humans and become monsters.

However, even so, there will still be many ordinary survivors in Evolution City who will volunteer to be experiments.

If they don't become strong, they won't have the ability to protect themselves, and they choose to rely on the strong, and as an ordinary person, they can only be a slave who is arbitrarily decided to live and die like pigs and sheep.

Most of the corpses have the same abilities, they have great strength, they don't know pain and don't know fatigue, but there are also a very small number of corpses who have obtained the dark matter that is also a probability in mutated zombies.

The corpse who controls the dark matter can have an effect similar to that of the Wild Iron, so the corpse with the dark matter also has a high status in the evolution city, which makes more survivors who have not evolved willing to be survivors of the laboratory.

Even if the probability of success is only 1 in 30, who knows that you are not that 1 in 30
