Nian Qi, who was taken care of by Mo Ying, fell asleep sweetly, put one hand into a fist on his stomach, covered his mouth with the other, and stuffed his thumb into his mouth to suck, looking at his small appearance, he seemed to be very satisfied. There were four heads piled up above his head, huddled together one by one, and there was a hint of warmth in his eyes.

After a while, the four womanizers who peeked at other people's sleep reluctantly raised their heads and returned to the living room to sit down. Nian Cheng and Ah Dan sat together, Mo Hui sat on Mo Ying's lap, and he didn't feel shy at all rubbing his sister's face, wanting to wipe away the smell that Nian Qi left on Mo Ying. Mo Hui, who has long been accustomed to turning on the sister control mode, completely ignored her by Nian Cheng and Ah Dan, looked at Mo Ying seriously, and talked about business.

Previously, Mo Ying asked Nian Cheng and Ah Dan to pay attention to the combination of the pair of high-level zombies, compare the situation of the other pair of middle-level zombies, and then find out some volunteers from the zombies to find out the possibility of the zombies reproducing. Nian Cheng and Ah Dan are very concerned about this matter, because they originally wanted the base to continue for a long time, rather than ending it in one generation.

After the beginning of the year, the high-level zombies inside the base have also moved their minds, they already have mature thinking ability, and they know that the zombies are dead and one is missing, which is not conducive to the long-term development of the base. If they can reproduce and continue their bloodline as before, after a hundred years, who can say that this world belongs only to human beings? To this end, they are willing to be volunteers, willing to unite with their own kind who have no emotional basis, in order to create hope.

The high-level zombies took the initiative to cooperate, and the zombies below the intermediate level were in a state of complete obedience. Nian Cheng and Ah Dan's work is simply not too easy, but they will feel embarrassed at some moments. And after the embarrassing stage, it is a serious research work, compared to the unnaturalness of Nian Cheng and Ah Dan, those zombies who participated in the research are much more open.

One by one, they said things that couldn't be dirty, but there was no embarrassment on their faces, and they looked like "I am contributing to the future of the base", which was really depressed and speechless. It's also a zombie, if it is a human being, even people who don't have a lower limit of discipline will not respond to this kind of thing of intercourse with people to provide data. Not to mention the bunch of human rights organizations staring. The slightest carelessness can take this research to a hundred heights.

And many things are magnified later. There was nothing wrong with it, but it became a big problem, thinking of this, Nian Cheng and Ah Dan were glad that they were zombies again. The place is also a base that only belongs to zombies. Not too much to worry about.

"After preliminary research. High-level zombies, including sixth-level zombies, all have normal physiological needs, and male zombies basically have morning erections, usually three to four times a week. It's mostly your own solution. Nian Cheng is now able to talk about topics related to "dirt" without blushing and heartbeat, and said indifferently, "Most female zombies will have the phenomenon of 'big aunt', but it is slightly different from the situation of human women, one is a short cycle, and the other is the consumption of body energy. It can be said that female zombies in special physiological periods will be about twice as weak as usual. ”

"Low-level zombies only have the need to devour flesh and blood, and have no normal physiological reactions and needs, so to speak, they only have the word 'eat' in their consciousness. Even when dealing with their own kind, unless the other party is higher than them and can be their leader, they will regard this kind of people as 'flesh and blood'. Of course, the flesh and blood of the same kind are the crystal nuclei of the brain to them, and they do not have other needs. ”

"As for the middle-level zombies, there are many situations, and their physiological reactions and needs do not have exact rules, but they are generally easier to control than low-level zombies. According to the maturity level of intelligence, mid-level zombies can be roughly divided into three situations, one is low ability level but high intelligence, one is high ability level but low intelligence, and one is increased wisdom as ability level increases. Most of the zombies are in the last situation, a little bit of promotion, a little bit of increasing wisdom, such as Ah Dan, his thinking ability is much stronger now than before. ”

Nian Cheng glanced at Ah Dan when he said this, but he got a roll of his eyes from Ah Dan, and he didn't care, he liked Ah Dan's appearance that he was not big or small, but if Dai Lu saw it, he had to say that he did not have the majesty of the emperor.

With a chuckle, Nian Cheng said: "The intermediate zombies in the last case are easier to control, and the physiological needs and corresponding physical reactions are also more regular, while the first two situations caused by special circumstances are more difficult to control. High-level zombies with low intelligence can always recover their intelligence after self-repair, while low-level zombies with high intelligence can also work hard to increase their ability level, but it takes time and the length of time varies. ”

"When the mid-level zombies in these two situations do not reach their own balance, the physiological needs and body reactions will be very unstable, and the combination in the unstable state is very likely to cause cannibalism. Such a situation appeared among the zombies who volunteered to participate in the research, but fortunately Dai Lu separated them in time, otherwise unnecessary sacrifices would have been caused. Nian Cheng thought of the pair of middle-level zombies who volunteered to combine for research, and couldn't help but sigh lightly, before finding out the feasibility of reproduction, every zombie in the base was important and could not be easily damaged.

After Nian Cheng added some more details, he talked about the depressing discovery, and said: "That pair of high-level zombies who have already been combined have been together for a long time, but there has been no reaction to give birth to life, and if it continues, there is not much hope." And the situation of the pair of mid-level zombies is even worse, they will become very irritable in the process of combining, if there is not a trace of self-control, I am afraid that they can fight with each other endlessly, and they have no good news. ”

"I suspect it's because the survival rate of zombie sperm is not high, after all, we are already equivalent to 'dead', how can a dead person give birth to a child? As for Xiao Qi's situation, I think it's because his mother is a human being, and as a mother, she is very healthy, so she gave birth to this miraculous life. Ah Dan took over the words, glanced at the expressions of the Mo Ying sisters, gritted his teeth, and said his preliminary judgment, "I guess that there is no possibility of giving birth to offspring among zombies, but it is possible to overcome this problem with zombies and people, or the combination of humans and zombies." ”

When the words fell, the two corpses were silent, if they said this, there was no way for the base to reproduce itself?

"What about the two of you, haven't you tried it with a female zombie?" Mo Ying's mind turned, and she looked at Nian Cheng and Ah Dandao. (To be continued.) )

PS: Nian Cheng and Ah Dan: Zhang Rui, take care of your daughter-in-law. Mo Hui: He can't care about my sister. Mo Ying: That's right! Zhang Rui: ......
