Li Qinghou's voice was very low, his expression was gloomy, and he said slowly: "Five hundred years ago, when the biochemical apocalypse had not yet come, human beings were the only intelligent race on the entire earth, and they were the only overlords, dominating the earth."

"It's a little desirable to think about, according to historical records, human beings at that time walked a kind of scientific and technological civilization, full of skyscrapers, straight into the sky, machinery roared, replacing human labor, and even some powerful scientific and technological weapons, thousands of miles away can wipe out hundreds of thousands of people, and even scientific and technological aircraft rushed out of the earth......" Li Qinghou's tone revealed a trace of yearning.

Lu Li also had this feeling, especially when he saw the ruins of the cities that had been occupied by mutants for countless years, although they were covered with moss and dilapidated, but those huge buildings that still reached into the sky still gave him a great shock, and sometimes he thought about what it was like to fly up to the stars and look down at the earth...... But that's all, Lu Li does not envy the scientific and technological civilization of 500 years ago.

Although the scientific and technological civilization is powerful, but with the help of external forces, according to some historical records, although science and technology prevailed in human society at that time, human beings themselves became worse and worse, and even diseased, colds and fevers at every turn, what so-called heart disease, cardiovascular, etc., the body was a weak mess.

And now, after the apocalypse, the former scientific and technological civilization was destroyed, but the surviving human beings really opened the road of bloodline evolution, and constantly strengthened themselves**, even if they can't become blood soul warriors, the strength of the body is still not comparable to five hundred years ago, what colds, fevers and other minor illnesses have been completely extinct, and heart disease, cancer and other major diseases that once made helpless have become historical terms.

This is the path of civilization evolution that human beings should take, and only when they are strong can they truly thrive. Moreover, now human beings have not completely abandoned all technology, like some practical small technologies are still used, but they are not as dependent as before, and are completely regarded as an additional auxiliary means, and all of them use source energy ore as the source of energy.

Take the means of transportation, although they can't go to the sky and the earth like before, and the speed is not slow, but there are very few people who use them to travel, especially the Blood Soul Warriors, who prefer to use their feet to step on the ground step by step.

Moreover, Lu Li believes that human beings continue to strengthen themselves with blood, and in the long run, they will one day surpass the scientific and technological civilization! Especially after comprehending the "Thirteen Seals of Casting Heaven" and comprehending the "Secret of Refining Blood with Long Fist", this idea in his heart is even firmer. 500 years ago, when scientific and technological civilization flourished, could human beings themselves achieve an acceleration similar to spatial teleportation?

Li Qinghou's words made Lu Li's mind wander and think a lot, and when he came back to his senses, the other party had already continued to tell the secret of five hundred years ago.

"At that time, human beings were the absolute overlords of the earth, and their scientific and technological civilization was prosperous, but they were still not satisfied, and they killed all species without mercy, leading to the extinction of many species. ”

"Especially after the development of human scientific and technological civilization reached a bottleneck, the society began to become turbulent, and the central centralized government's control over the local government gradually weakened, and in the end, a situation of family separation was faintly formed...... And that's not even the scariest of all. ”

Li Qinghou showed a trace of pain on his face, and continued: "The most terrifying thing is that at that time, in order to break through the current bottleneck of scientific and technological development, and to strengthen themselves, almost all the families began to secretly develop biochemical technology research. ”

When Lu Li heard this, he also vaguely guessed something, is the research of biochemical science and technology? I am afraid that this will finally lead to the prelude to the coming of the biochemical apocalypse.

"To conduct biochemical science and technology research, there must be a real carrier, and it must be alive!" Li Qinghou's voice became deeper and deeper. "At that time, there was only one creature on Earth that had genes similar to humans, and that was apes, especially one of the ethnic branches: chimpanzees, whose genetic makeup was most similar to that of humans. ”

Lu Li had a guess in his heart and asked, "So at that time, human beings regarded chimpanzees as living carriers for biochemical experiments?" After receiving Li Qinghou's affirmative answer, Jian frowned, glanced at the little orangutan nested in his arms, and continued to ask: "Did the ape group at that time also have high intelligence?"

Li Qinghou frowned and thought for a while, then shook his head and said: "Although the intelligence of the orangutan group is second only to humans, it is far less spiritual than this little guy, and the intelligence of an adult ape is equivalent to that of a human child who is four or five years old......

Li Qinghou continued to narrate, his voice was sometimes low, sometimes angry, and he also brought Lu Li into the world of human loss and bloody violence five hundred years ago, and made his heart full of inexplicable sorrow, sad for mankind itself, if it continues to develop like that, the end of mankind will come sooner or later.

From the other party's narrative, he also knew some secrets that were not known to the world, for example, in the technological society five hundred years ago, there were very few cultivators living in it, but it was very difficult to enter the industry, and the number was extremely rare, a bit similar to ancient martial arts, but this was not what shocked him the most.

According to Li Xiaoting, in order to make a breakthrough in biochemical science and technology, human beings at that time wantonly captured chimpanzees in the wild for biochemical practice, and even in the end, they were no longer satisfied with the ape population, and began to quietly use live humans for experiments, the elderly, women, and children...... In the end, even pregnant women were not spared, and the methods were extremely cruel and had completely lost their humanity.

In the end, the biochemical experiments of humans finally came to fruition, but they created two new races with high intelligence, one is the ape race, and the other is the mutant, but this is a disaster for humans.

First of all, the first chimpanzee with high intelligence awakened to the consciousness of the race, and escaped from the real yàn base because of the murder of the mother savor. In the next few years, when the other party came back again, it had grown to the point where the human cultivators were helpless, and in full view of everyone, they launched a journey of revenge, forcibly destroyed a human base, and then took the tens of thousands of apes rescued from captivity by the major human forces to start a great escape, which also officially opened the prelude to the rise of apes.

On the other hand, human beings have finally suffered retribution for using their compatriots' hands and feet to make biochemical ** real yàn, and with the frequent murder of mutants in various places, human beings have begun to embark on a two-point road.

More than half of the human race was infected by the biochemical virus, and the human race went from the inside to split, officially splitting into two opposing and undying races, and the biochemical apocalypse broke out completely.

"So, after the revenge was successful, the chimpanzee disappeared with the ape clan, but how can there be a shame?" Hearing this, Lu Li was a little puzzled.

Li Qinghou smiled bitterly and said, "Don't worry, because there is still a story behind ......"
