Zombies in the last days will evolve.

Until the late end of the world, there were seven levels of zombies.

At the beginning, the zombies that appeared at the end of the world were basically the lowest level zombies, and their bodies would decay until only the skeleton was left from the moment they became zombies.

These lowest-level zombies are the first-level zombies, and they are also the weakest zombies, they are the hard-working models who exist in large numbers in the early apocalypse to improve the experience value of human beings, howling day and night, telling people where they are, guiding people to come and destroy them, using their sacrifices to increase their own experience points, and laying a solid foundation for the awakening and upgrading of abilities in the future.

And this lowest-level zombie, in addition to the physical attributes of the body before it completely decays is far stronger than when it was a human, when the body decays to the point that only the bone frame remains, although the hardness of the bones is also harder than when it is a human, but without the protection and cushioning of the flesh tissue, when the impact is large enough, it is easy to fall apart, but when they only have the bone frame left, the experience points they provide can no longer meet the needs of human evolution, and are disliked by the vast majority of abilities, even if they appear around them, they also belong to the kind of existence that disdains to consume abilities to destroy。

In addition to being more resistant to beating than the first-level zombies, the speed of body decay is much slower, the difference is not too big, but there will be some exceptions with extraordinary talents, these exceptions are better than ordinary people in some aspects of the body before they become zombies, so when they become zombies, there will be a certain probability of awakening the abilities that will only appear in the third-level zombies, but because of the limitations of their own level, their ability attack power is very weak (Lu Luan, The one Wang Xuan encountered was a second-level zombie with spiritual abilities).

There should be no crystal nucleus in the head and skull of the second-level zombies, but it is not absolute, and those special second-level who have awakened the ability will have a certain probability of forming a small crystal nucleus the size of a fingernail in the head, but there are too many impurities in this crystal nucleus, and it is easy to have an accident if it is absorbed and used, and the people who have learned the lesson can no longer look at it, so it is basically used as a circulating currency in the hands of ordinary people, which is also the only crystal nucleus that most ordinary people can get under the premise of saving their lives.

From the third level, the body of the zombie will no longer decay, and as their level increases, the skin will become more and more tough, ordinary swords and pistols will not hurt them at all, except for those with weapons of mass destruction, only high-level abilities can fight against them.

Level 3 zombies,There will be a crystal nucleus in their heads,This is the source of their power,It's also an important prop for the ability to upgrade,Although the level 3 people have crystal nuclei,But not every one will awaken the ability,But their physical strength is ten times stronger than ordinary people is also not to be underestimated,If the level is lower than them The ability vain tries to destroy them,It will be easy to be killed by them。

If the strength of the zombies from level one to level three gradually increases as if doing addition, then the strength gap between the zombies of levels four to six should be calculated by multiplication, starting from level four, the level of zombies will increase by several times for each level of zombies, but sometimes when encountering some unreasonable, high-level zombies that do not mutate according to routines, multiplication may not be able to calculate its true strength.

If the difference in strength between the first-level zombie and the third-level zombie is like climbing a staircase, then the gap between the third-level and the fourth-level is like a mountain that can barely be seen, the third level is at the foot of the mountain, and the fourth level is on the top of the towering mountain.

The zombies of the first to the third level are chasing and killing humans by virtue of their instinctive thirst for fresh flesh and blood, and the zombies of the fourth level have awakened their consciousness, and their intelligence is like that of children of a few years old, they will think and learn simply, and the use of abilities will be more handy than the third-level ability zombies, and if they are not killed by humans at the beginning and escape, they will learn a lesson, and they will not make the same mistake next time, which is not very easy to deal with zombies.

Level 4 is starting to be difficult to deal with, and level 5 zombies are naturally even more difficult.

The appearance of fifth-level zombies will slowly fade away from the ugliness and horror of zombies, and return to their former appearance as human beings, and their intelligence is like that of teenage children, with stronger thinking and learning ability, even if it has not suffered in the hands of humans, but if it sees other zombies or humans themselves are planted in the hands of humans (companions), it will also learn a lot of things from it, become more intelligent and cunning, and some will even set traps for humans if they learn enough, so that humans panic and mess up。

And the sixth-level IQ that is only one step away from the highest level is higher, except that there are no superfluous human emotions and six desires, their thinking is almost the same as that of a normal adult male, although due to individual differences, there will be more intelligent and stupid, and their appearance has almost returned to the appearance when they were still human, but the skin without the slightest blood color can still be seen by sharp-eyed people, but the smart ones will also use clothing to disguise themselves, and some are even addicted to disguising themselves, hiding themselves, and blending into unaware humans。

Not only that, most of the zombies at level 6 will remember the memories of when they were still humans, but they will not regain their humanity after they have long lost their feelings and their sense of right and wrong has been distorted, and humans have no special meaning for them except for food.

As for the seventh-level zombie, its strength cannot be measured by the algorithm of the previous levels, but according to the statement, the seventh-level is the top of the zombie evolution and upgrading, and the zombies who ascend to that level have the strength to compete with the sky, if it appears, the entire human race will be completely wiped out.

However, such a terrifying existence has never really appeared in it.

Whether it is in the apocalyptic strong woman that Kong Guoxuan has seen, or in the apocalyptic text that Fu Rongyue has seen that crosses the female supporting role's counterattack, it has not appeared even once.

But these two chicks can know it, all because there was a sixth-level zombie in the later stage who almost succeeded in evolving, but at the last moment, Fu Yiqi took people to yin, and it fell short, but even so, it still strengthened several sixth-level as many as it did with one foot that had already crossed the seventh-level threshold.

And in order to stop the evolution of the zombie king, many powerful high-level abilities were sacrificed, and the human race was greatly damaged because of this.

However, for the sake of his own evolution, the zombie king slaughtered and devoured a lot of his kind, so in the battle to prevent its level evolution, the remaining sixth-level zombies temporarily formed an alliance with humans, and took his high-level zombies to crusade and stop it, and finally only two sixth-level and several third-level zombies survived, and the zombies also suffered heavy losses.

Humans and zombies are fragile allies on their own defense, but after the First World War, neither of them had the strength to sneak attack and destroy each other, and when both sides were helpless against each other, everyone "shook hands and made peace" and signed a "peace treaty" that could get along as friendly as possible.
