On the way to the flight, Duan Fei couldn't help but recall the fierce battle last night and a mystery afterwards... lā

The evolutionary effect of the evolution key on humans is to make it hard, enhance the ability, and restore the soul, and for mutant beasts and zombies, in addition to the above three points, there is one more important and most attractive - gene nucleus evolution, evolutionary power can raise the gene nucleus in the monster's body to the level, so that mutant beasts or zombies can adapt to the powerful effects of this evolution from the inside of the body to the outside of the body, but at the same time, the evolution effect produced by this incomplete evolution key is also not perfect, After a certain period of time, this evolutionary effect will disappear, and the monster or zombie will return to its original state, original level, and original appearance, even if the evolutionary effect is applied to people.

However, recovery is restoration, and the genetic nucleus in mutant beasts and corpses has really evolved, and this evolution is not from within, but from an external evolutionary force forcibly evolving the genetic nucleus, because the body and soul are not in this class in the first place, and if they are hastily forced to evolve, the body will have backlash and adverse reactions. However, this side effect is still minor to humans, what really has an effect is the gene nucleus in the body of the mutant beast, in Duan Fei's previous life, the vigorous great evolution tide caused by a high-level evolutionary, in many experiments, the high-level evolutionary once tried to inject evolutionary power into the body of a wild mutant beast, so that its body and soul can be evolved.

Because it was an E-class little zombie selected, it didn't pose a threat at all at that time, and the gene nucleus was taken out after killing the zombie that had gotten the power of evolution, and as expected, the gene nucleus remained in a state of evolution, that is, the appearance of an increase in level, and at the same time, the senior evolutionary came to several conclusions after more similar experiments.

If you kill a mutant beast affected by the evolutionary power, it will undoubtedly save the evolutionary power in its body, and you can also get an evolved gene nucleus, but if you take the gene core after the evolution effect has dissipated in the past, you will only get a mutant beast gene nucleus before receiving the evolutionary power.

It was based on these conclusions that the human base where the advanced evolutionary was located frantically sent the strong to plunder the mutant beasts that were relatively weak but evolved into high-level monsters in a short period of time after the increase in evolutionary power, and that human base obtained twenty-three A-class gene cores, hundreds of B-level gene cores, and three extremely valuable S-class gene cores in less than a month. The lucrative base soon became the target of public criticism, attracting the attention of all parties and speeding up the time of annihilation.

Yesterday's mermaid mutant beast was blessed by the last and largest evolutionary power from the fragment of the evolution key, and successfully evolved into a monster with mid-level A-level strength, but unfortunately, before it could understand what other abilities its body had besides the increase in hardness, it was smashed into half death by Duan Fei's three ability changes. In this way, even if it evolves, it has no effect, and in front of Duan Fei, even if it is the arrival of the late A-level, it can only be beaten.

After killing the mutant mermaid, Duan Fei not only absorbed all its life energy and converted it into his own energy, but also accidentally harvested an A-grade mutant beast gene nucleus.

With the intervention of Duan Fei's bug, the process of this world has been much faster, but the highest-level mutant beast that humans have known is still the peak of A-level, and as for the S-level, there is still no one in the world so far. Since Duan Fei was still in the late stage of the apocalypse when he died in his previous life, that is, when a number of bases were established, the biggest enemies of mankind were only mutant beasts and a few inconspicuous little zombies. In the days to come, if there are any major changes or changes, Duan Fei really doesn't know.

However, one thing is for sure, in the late apocalypse, the S-class was not the top level, and it was rumored that the most powerful Awakened warrior in the human forces at that time was a peerless powerhouse whose strength was beyond the S-rank.

Duan Fei's arrival this time helped Skynet destroy the biggest enemy of the Eastern Branch, and the degree of its contribution value was instantly raised to another level, and last night after returning to the base, Duan Fei found Fengya alone after the celebration banquet.

It stands to reason that the gene nucleus that Duan Fei obtained by killing the mutant beast was originally his own, but considering that this is an A-level water mutant beast, and most of the awakened people in Yanhuang Dacheng and the Star Alliance are still C-level, and even the B-level ones are only a handful, and now they can only be put back, since he learned that Fengya knows so many secrets, Duan Fei simply didn't do anything and had a secret deal with him, and he used the A-level gene nucleus as an exchange object. And Fengya is at the cost of two-thirds of the evolutionary power in the fragments of the evolution key in his body.

A large part of the evolution power was poured into the one-third of the evolution key that Duan Fei had taken out of the mermaid mutant beast's body.

One is the evolution key fragment, the other is the A-level mutant beast gene core, in the face of temptation, Feng Ya still chose the latter, it's not that he doesn't want the remaining one-third evolution key fragment, but now their eastern branch base is too lacking in advanced mutant beast gene core, in this battle, Feng Ya understands that just relying on these five cadres is not enough, in the face of other mutant beasts hidden in the sea, the defense line of their base is as if there is none, as long as these few cadres who can fight are trapped, At that time, it will not be far from the time point to destroy the base of the Eastern Division.

Even if Fengya himself has an evolution key fragment, it also has no offensive effect, and if it is face-to-face, it will be a dead end or a dead end.

What's more, the evolutionary power of the evolution key fragment in the body is still sufficient, and transferring a part of it to the other fragment that has been depleted in the past also has another benefit for Fengya, which can sell Duan Fei a great favor, Duan Fei's strength is obvious to all, with the power of one person to kill such a huge number of mutant beasts in an instant, if you don't use the god of war to describe it, you really can't think of any words.

Although Duan Fei didn't find his sister, he was very satisfied to know that his sister was still alive, and not only that, but he also got a fragment of the evolution key with unlimited potential.
