Think about how many materials must be in the security zone, most of the materials in several cities in the south have been involved in this security zone, and according to the sixth master, there are at most 10,000 people in this security zone, all of whom are leaders from all walks of life.

In particular, there is a eugenics program in the safe zone, and all the children who have entered the safe zone are brought in by the first generation of adults who have entered the safe zone, and once they enter the safe zone, these children will be collected by the Yongsan Research Institute for genetic collection and use for optimal matching.

In the future, when these children grow up, the two people with the best genes will be combined under the arrangement of the safety zone, and then the people with the second highest quality genes will also be optimized and matched, leaving the next generation with the best quality.

And such a genetic optimization plan, in Qing Xiran's view, if you ignore human nature, it has a certain scientific reason, after all, human beings can make such an existence as a safe zone, it is impossible not to take into account the problem of population explosion, the first generation of population into the safe zone can still be controlled, after all, they are all people with children and daughters.

But when the children of the second generation grow up, they will have to combine freely, so if the population is not controlled, as soon as the base rises, the hoarded materials will not be able to meet the skyrocketing population, especially in the next few decades, what will the ground look like, the security zone is not predictable at all, and they still have a chance to get out of the safety zone?

They even have a plan for a future where they can't get out of the safe zone, and how they will survive underground forever.

The end of the world is a disordered world, the genes of all living things are in disorder, the variability of genes indicates the future world, that is, the hegemony of the heroes, today a dinosaur, tomorrow a Monkey King, that is possible, according to the logic of the safe zone, rather than running to the ground to compete with the creatures for hegemony, it is better to be in a corner of the ground.

Therefore, it is in line with scientific logic to strictly control the population and eugenics.

However, it is not in accordance with human nature.

Where in this world is it possible to say that if you are united with this person, you must be united with this person with all your heart? Don't have your own preferences? Haven't had someone who has your heart set for you? Haven't you been moved by someone to the point of softening your heart because of a certain moment? Naturally, there is, so if there is, how can it be combined with another person whose genes are more compatible with you?

This reason is very simple, if Qing Xiran wants to be entangled, Xu You is not the one who matches her genes at all, and even less than 30% of the match, if she wants to combine the best genes with her, she must find another man with a brain as developed as her, and even a man with a brain more developed than her, and the offspring born by the two will have the opportunity to surpass the parents' minds and give birth to a more developed person.

This is the best match for her.

However, such a man is placed in front of her, Qing Xiran will not choose, she thinks that Qing Yiyi is very good, she is the best and best daughter in the world, give her gold and silver mountains, give her tens of thousands of crystal nucleus veins, and even give her the entire planet, she will not change!

Xu You, as a pig teammate, is the only one who can make her ignore all logic and rationality among all the men Qing Xiran knows, and the only one who can make her feel happy from the bottom of her heart.

So she is happy to be with Xu You, and there is no way to combine with another person.

Therefore, out of the consideration of human nature, although Qing Xiran can understand the eugenics plan of the security zone, she will not implement this plan in Xiangcheng, nor will she interfere with the safety zone, whatever, she only needs to ensure that her mother and the sixth master can live safely in the security zone, Gu Yu must rely on Xiangcheng 100% in terms of materials, then that's fine.

That's it, Qing Xiran and Xu You chatted with each other, and Xu You and Qing Yi fell asleep like this, the long night was long, Qing Xiran lay sideways beside Qing Yiyi, looking at the faint bedside light, and on the other pillow, Xu You's handsome face was asleep.

She smiled, didn't wake up Xu You, only closed her eyes, let her brain enter physical hibernation, and her consciousness sank into the world of consciousness in her mind, and continued to send messages to Bai Xiao and Luo Nan.

After a few days of warm-up, the crystal nucleus bank, mission center and trading bank in the North District have been established, although the people in the North District are very disgusted with going out of the city to fight monsters, but such as the four districts of the east, west and south, now they don't feel that going out of the city is a particularly unacceptable thing.

On the contrary, many men with great strength are no longer satisfied with farming at home, or working in a factory, or looking for a mediocre job in Xiangcheng, they actively join the civil team of Chongling, and under the leadership of their respective captains, they go out of Xiangcheng again and again to find materials, which not only supports themselves, but also sells the excess materials to the trading house in exchange for crystal nucleus coins for wealthy families.

The current civil team is very different from the previous one, before it was because no one in Xiangcheng had joined the civilian team at all, so Chongling had to divide the 5,000 garrisons in his hands who fled from J City to Xiangcheng into ten-person squads, and each team would leave one or two vacant seats for the people in Xiangcheng and lead them to the outside of the cordon.

Now many Xiangcheng people have been trained, everyone's consciousness has changed drastically from before, and they no longer feel that it is terrible outside the cordon, in other words, Xiangcheng people's fighting consciousness has been cultivated.

Therefore, Chongling will let the garrison of J City choose for himself, whether to stay in the circle of the civil team to lead the team, or go to Xiangcheng to find a house and farm the land, or join Chief Xu's Xiangcheng team.

As a result, many J City garrisons have chosen to join Xu You's Xiangcheng garrison, and they are still more willing to return to the collective to shine, and only a few have chosen to stay in the circle of the civilian team to lead the team, and find a house to farm the J City garrison, almost none.

On the contrary, the first batch of Xiangcheng men who followed the J City garrison out of the cordon, in a short period of time, most of them have grown into captain-type characters, and they are also recruiting troops to pull teams and engage in teams.
