"We are the safest and most prosperous area here, so sister, you can stay here with confidence."

While explaining to Xingyun, Zhang Yu did not forget to input the thoughts left to Xingyun.

"The black area block is the territory of high-level zombies, and the white area block is the territory of the human base."

"After this thousand years of evolution, human beings have become mutant humans who are born with at least one kind of ability, and after this thousand years of evolution and development of zombies, they will also become very strong for a period of time after infection. Evolve into a high-level zombie."

"Higher zombies are intelligent and can think like humans, but they are ferocious and brutal. The meaning of survival is to attack humans, thereby increasing their zombie compatriots."

"Of course, it may also be related to the human beings themselves before they were infected."

"Those higher-level zombies will not have the human memory before being infected, so in a sense, once infected, it is death."

"The natural lifespan of high-level zombies is more than three times that of humans, but today's average natural lifespan of humans is only about 60 years per person."

"Zombies can't reproduce, humans can, but the number of humans has dropped by two-thirds just after the end of the world. After this thousand years of development, the number of humans has not increased, but the human lifespan has become shorter. In the battle between humans and zombies now, humans are at a disadvantage."

"But as long as we develop a genotype that can combine human genes with those of previous eras, we can turn the offensive and turn the disadvantage into an advantage."

In fact, as long as Xingyun agrees and stays here, it is best to promise to reproduce with someone here, and this problem can be solved.

But Zhang Yu didn't dare to say it so straightforwardly, otherwise he would definitely scare the young lady away.

Although Zhang Yu didn't say it so directly, Xingyun understood the meaning revealed in the words.

Her arrival is the hope of human victory in this apocalypse.

Xing Yun pursed her lips, her eyes deepened a little.

She is relatively safe now, but if her existence as a pure-blooded human is known to higher-level zombies, it is estimated that it will lead to a fierce battle.

"By the way," Xing Yun raised her eyes, blinked her long, thick eyelashes, and asked, "The current high-level zombies are also organized and disciplined, with leaders?"

Zhang Yu didn't know why Xingyun asked that, but he still nodded.

"Yes, but they can't use the power of technology like humans, and can only rely on their own abilities and wisdom."

Although high-level zombies have wisdom, they only have a thousand years of development time. The wisdom accumulated by human beings for tens of thousands of years is an existence that they cannot steal.

After all, Xingyun is someone who has experienced strong winds and waves. Although she doesn't know whether Lord God Emperor is in the human camp or the zombie camp, she still decides to stay here to observe and observe.

If there is no Lord God Emperor in the human base, she will find a place to retreat and practice for ten and a half years. As a reward, she will leave a little of her own blood for them to study on their own.

Then go out alone to find Lord God Emperor.

Whether it's a zombie or a human, Xingyun will always find him.

Zhang Yu spent a long time explaining to Xingyun the state of the world and the situation in the core human base, including everything that Xingyun did not understand.
