And this has slowly become the general trend, because in the face of more and more ferocious monsters, people have to hold together tightly and gather strength to resist, otherwise they will only be broken by monsters one by one.

They are no longer the masters of this world, although they now have enough ability to gain a firm foothold, but this is just a partial friend, for the whole world, they are insignificant, because the total population of this world is as high as 100 billion people, and now there are only less than 10 million people left, although this is the people who still exist according to their statistics, and among the 100 billion people, 10 billion of them are monsters, and the others are for various reasons, They all succeeded in keeping themselves from being assimilated by monsters, but at the cost of being crushed.

In fact, when a disaster occurs, people find that even if they are infected, they still have their own sanity at the first time, and when the virus is about to hit the brain, they will also have an early perception, as long as they pull off the bomb on their body before that, they can ensure that they will not become such a monster.

And it is precisely because of this that the number of monsters has been successfully curbed from continuing to rise, but even then there are always some losses, which also makes the total number of monsters although it has not risen as drastically as before, but it is still rising little by little, after all, their total number is powerful.

But even so, in fact, the overall number of monsters at that time was actually only about 1 billion, in fact, Zhang Shuai was also very puzzled, why only 100 million monsters, the total number of people as high as 100 billion, but there is no way to absolutely eliminate it?

Later, Zhang Shuai found the answer, that is, in the early days of the first spread of the virus in that world, as long as someone died, they would become monsters, which not only would normal deaths and unnatural deaths become like this, but also the initial virus could be transmitted through the air.

This also makes them have no way to kill monsters absolutely, but instead cause their own casualties, of which the number of soldiers is as high as 70%.

You must know that the military-civilian ratio itself is not too high, even if the countries still had very complete armies at that time, but at that time they were still in a state of mutual containment, and it was impossible for the major powers to reconcile and be honest with each other because of a biochemical mutation event that I don't know if it would turn into a major accident.

At that time, they still had disputes and arguments with each other, and they were intrigued, and everyone wanted their hostile countries to be affected by monsters in advance, and then they could take advantage of this opportunity to carry out internships, economic suppression, and even military suppression.

But eventually, when the monsters and things became more and more serious, and they had to take it seriously, everything was over, and the total number of monsters at that time had reached 100,000.

It's impossible for all people to have time to destroy themselves in such a timely manner, and most of the monsters are not aimed at them, and in the later stage they began to kill each other, because at the beginning because the total number was relatively small, they focused most of their attention on humans, infecting humans and not killing them, but with the growth of time, such changes slowly disappeared.

Because they began to become less attached to humans as before, just infecting them, starting to eat all the people they killed instead of stopping, increasing their overall number, and in fact when the number of monsters reached a certain number, some monsters had begun to breed with each other.

It is precisely because of this crazy reproductive ability that they have no way to deal an effective blow to monsters, coupled with that crazy contagion ability, there was no injection of antibodies in that generation at that time, and this antibody.

After all, at the beginning, even if there is a small amount of research, how many people will directly start to develop very targeted antibodies and anti-infection things, although they are researching, but they will not take it too seriously, plus this virus, it is not so easy to be studied.

However, in the end, the antibody was introduced, but when the antibody was launched, the entire human race was already at a disadvantage, which is a bit ironic, because the antibody was finally discovered, and the resistance was also formed from the mysterious element found in the most underground ground.

After a certain amount of special changes and changes, this mysterious element eventually became their counterpart, and the reason why those airborne viruses can be airborne is that these mysterious elements are 70% similar to the structure of the virus, which makes the mysterious element can act as part of the vaccine.

However, it is understandable how expensive it is, and when everyone starts to inject their antibodies, they find that they themselves are gradually starting to develop the virus.

This initial discovery surprised everyone, and even the important laboratories began to study it immediately, after all, such a situation had not been discovered when they experimented on animals and humans before.

However, in the end, after careful research and a series of examinations, it was found that this newly born virus is mild to the human body, and has a certain resistance to foreign viruses, and this makes those monsters can no longer spread through the virus in the air, because once the virus in the air enters the human body, it will be killed by those warm viruses.

After people begin to produce viruses in their bodies, some people's bodies begin to gradually produce markings, and these have strengthened their whole human quality and even ability to a certain extent, and eventually these people are called mutants.

Because even if it is injected, not all people can produce a very large number of warm viruses, because there are not such good things in this world, and only those who need to have type O blood can have the ability to accommodate the virus and be compatible with each other, which makes them, people with type O blood, become the most basic condition for becoming mutants.

And when he becomes a person with type O blood, he also has the ability and experience to fight monsters, because most of the people whose bodies produce markings, the reason why they produce markings has a common characteristic, that is, they have had fierce battles with monsters, and successfully killed monsters, this kind of combat is a close-quarters battle, not a battle with long-range firearms to kill.
