Zhang Cheng was very curious about why he suddenly increased his strength at a dangerous moment, and why he suddenly felt so painful in the end. So he inquired about it with the Lord God. The answer was that he had unlocked the first-order genetic lock. The so-called genetic lock refers to a certain shackle in human DNA, and unlocking this shackle can enable human beings to evolve in all aspects, and this main god space is to stimulate the potential of human beings, so as to produce evolution. As for when exactly this space was built, who built it, and why did it force humans to break free from this shackle and evolve, Zhang Cheng was told that he was not qualified to know yet.

As for why there is such a feeling that life is worse than death in the end, it is because when humans unlock the first order of genetic locks, their bodies produce an adrenaline containing a highly toxic substance, and that painful feeling comes from this highly toxic substance. When certain qualities of the human body reach a certain level, it will improve the immunity to this highly toxic substance, and when humans are in danger, the adrenaline produced will also neutralize some of the toxins, so to successfully unlock the first-order gene lock, the above two conditions are indispensable, otherwise they will die because of the highly toxic effect.

However, there is a special case, that is, the T virus and antibody serum, in addition to turning people into zombies who only have the desire to eat, the T virus can also directly make people unlock the first-order gene lock, and the antibody serum can not only restore the mutation of the T virus, but also neutralize the virulence produced when the first-order gene lock is unlocked. However, because this method does not neutralize the process of highly toxic substances through its own conditions, the range of ability enhancement is extremely limited, and it can be said that it only unlocks the first-order gene lock to prepare for the future unlocking of the second-order gene lock, and the ability is almost not enhanced, which is actually not conducive to its own development.

This information can only be accessed by those who have unlocked the first-order genetic lock. However, there is another piece of information, Zhang Cheng doesn't know whether it is good or bad for him, that is, while he unlocks the first-order gene lock, his body also contains a virus with a strong mutation, that is, the mutant T virus in the body of the creeper who absorbed Xiao Horror's DNA. Because there are two kinds of poison that permeate the whole body, the process of Zhang Cheng unlocking the first-order gene lock is several times that of usual, but with his own ability, it is absolutely impossible to completely neutralize the two highly toxic substances, and if he continues, he will inevitably die, and just when Zhang Cheng was close to death, Xiao Wei happened to inject him with antibody serum, neutralizing the remaining small part of the toxin, and Zhang Cheng saved his life. And because the duration of unlocking the gene lock is longer than normal, the extra part of the process produces an unknown mutation in Zhang Cheng's body.

What is the unknown variant? Zhang Cheng asked the Lord God. The Lord God righteously explained: "Unknown mutation is a change in the biological organism that does not know the direction of development. ”

Damn, you're a dictionary of words! Zhang Cheng raised his middle finger into the air.

In fact, the probability of this happening is really small, first of all, you have to have a T virus in your body, and at the same time, this T virus has to produce a high evolution, and at this time, you have to unlock the first-order gene lock, and you have to inject antibody serum when you are close to death. Taken together, it can be said that a second case is almost impossible to occur, so it is understandable that the main god does not know what kind of mutation will occur.

But in any case, his own strength has indeed improved greatly, and now Zhang Cheng's physical fitness is: intelligence 213, mental power 192, cell vitality 418, nerve reaction speed 364, muscle tissue strength 396, and immunity strength 280. And what makes Zhang Cheng most pleased is that the blood clan skill, that is, the kind of black flame, can already be summoned at will, input energy to Na Jie, there will be a faint layer of black flame enveloping the fist, one punch can penetrate the 10 cm thick titanium steel plate. However, despite its great power, this skill can only last less than 5 minutes, after which it will cause a sense of detachment.

In addition to its own strengthening, the rewards for this horror film are also quite rich. Zhang Cheng received a total of 5,234 bonus points. Wang Jiahao didn't destroy a single monster, but because he completed a side quest, he got a total of 3,000 bonus points. The ghoul also gained a lot this time, since Zhang Cheng gave him his infinite bullet desert eagle, most of the zombies were ghouls with one shot in the head, and almost all of the more than 20 lost dogs died under his gun, counting the 1000 reward points for successfully surviving, the ghoul got a total of 1283 points, judging from this value, he alone killed more than 500 zombies, it seems that the difficulty of the main god of this mission is not small.

As for the side plots, what Zhang Cheng knows is the two C-level side plots he got and the one C-level side plot that Wang Jiahao got. And Xiao Wei, who got the virus sample, must have also gotten the side plot, but Zhang Cheng didn't dare to ask Xiao Wei to return the original D-level side plot, because when Xiao Wei gave himself a burdensome combat uniform, he shamelessly said it, and also injected himself with an antibody serum, which saved his life, and after that, Xiao Wei didn't blackmail himself for a sum of money, which was already very good.

Just experienced life and death, both Zhang Cheng and Fang Ming wanted to take a break as soon as possible。。。。。。 Mental rest, of course. Therefore, Zhang Cheng briefly introduced Wang Jiahao and the ghoul to the use of the main god space and room, and told them that the reinforcement aspect would be studied together tomorrow, anyway, there were still 10 days, and there was no hurry to do so. With that, he walked towards his room.

Zhang Cheng chiluo leaned comfortably on the big bed, sipping red wine and eating desserts, replenishing the physical strength he had just consumed. Mi Qi's face showed a hint of red tide, and she put a single on her body, stuck behind Zhang Cheng and wrapped her arms around her, panting slightly, and her posture was extremely attractive. And Ah Zhen (if you don't know Ah Terrible, please see Chapter 9 of Volume 1) stood with his back against the wall, sticking out his tongue, pitifully watching Zhang Cheng stuff the delicious desserts into his mouth one after another, with an extremely aggrieved expression. Experiencing this situation, I felt a little calm in my heart, and Zhang Cheng, who was in a good mood, beckoned, and the amnesty Ah Horror rushed into Zhang Cheng's arms like crazy, and as a result, Zhang Cheng spilled red wine. Zhang Cheng's roaring voice and Mickey's beautiful laughter came from the room。。。。。。
