Bai Xiaofei's last memory was that he was supported by Qiao Feng, entered a house, and fell asleep.

This is the most restful sleep Bai Xiaofei has slept in since he went to another world, here, he is like returning home, he no longer needs to be scared, no longer needs to be vigilant all the time, and no longer needs to be ready to fight every minute......

……

This is the third day of Bai Xiaofei and his party to the Xia tribe, Bai Xiaofei took Xiaohui and Xiaowei to go shopping, and from time to time Xia people greeted Bai Xiaofei warmly, because Bai Xiaofei is not only the answer of King Qiao Feng, but also the hero who killed the three-headed beast, the three-headed beast as big as a Boeing plane was arranged by Li Shimin to move back to the Xia tribe and was distributed to the people, and many Xia people were able to evolve because of this, and Bai Xiaofei can be called a great benefit to all beings.

It is said that it is shopping, but in fact, there is no shop pù like the big city of Yanhuang, that is, there are some things on the side of the street that are cushioned with leaves, some are the meat of unknown animals, some are fruits, and some are ores with five-colored light.

Bai Xiaofei and the others are no longer surprised, the Xia tribe is a very primitive tribe on the surface, there are no schools, no hospitals, no police, no prisons, no bank money, even Qiao Feng, the king, usually has nothing to do, just kill monsters, his subordinate ministers are actually a group of violent elements who follow Qiao Feng everywhere to fight monsters, what kind of civil affairs and economy, no one cares about it at all.

The reason is very simple, in this other world, in addition to evolution, it is evolution!

Bai Xiaofei and others privately chatted with Yue Fei, Li Shimin and other Xia people and learned that everyone in the Xia clan has evolved since they were born, and even since they ate their first mouthful of breast milk, Xia people who were babies began to mutate, they don't need school, because when they evolve to a certain stage, their consciousness will naturally awaken, just like they are born to know, they don't need factories and workshops, because evolution can avoid the cold and heat and make their limbs sharper than any weapon, so, what military, economy, people's livelihood, all don't need to be considered, The only thing Xia people have to do is evolve.

The Xia people don't even have a history, they never record any historical materials.

Now, Li Shimin, who was shopping with Bai Xiaofei and others, said: "History? We don't need this kind of thing. His face turned grim: "It's good that we can survive, no one will think about remembering what happened in the past." ”

Bai Xiaofei was stunned all of a sudden, this, this is still saying that "taking copper as a reference, you can be dressed properly; Taking people as a reference, you can know the gains and losses; Taking history as a mirror, can we know the rise and fall of the "great king"?

He couldn't help but say the above famous words for a while, and Li Shimin nodded thoughtfully: "The person who said this has some truth, but this sentence is a fart at all!" ”

Li Shimin pointed to the huge dungeon and said, "Bai Xiaofei, do you know how long this dungeon has been stored?" ”

Bai Xiaofei touched his head: "Such a great project, to say the least, it will take centuries to excavate, right?" ”

Li Shimin shook his head: "Wrong! Dungeons are formed naturally within a year! ”

Li Shiming told Bai Xiaofei that the Xia people were not born to live in the cave, before this, the acid lake had not yet appeared, and the lonely peak did not exist, and the Xia people had to fight with the hot and cold weather every day, and the sudden storms and rains, and countless monsters fought to the death.

However, suddenly, the earth shook violently, and the lone peak came out of thin air, and then, the acid rain kept falling, except for the strongest and most evolved Xia people, the vast majority of Xia people were directly corroded into mud. Fortunately, because the acid rain is so corrosive, even the earth has been corroded, and there are incomparably huge potholes, and the acid water gathers in these huge potholes, and finally forms an endless sea of acid.

Part of the acid rain flowed into the ground, eroded a huge cave underground, and then, the acid rain merged into an underground river, and finally disappeared, and when the acid rain finally stopped, the Xia people discovered this huge underground world.

Li Shimin said: "The underground world is much safer than the ground, so our whole family moved underground, and through guò continuous childbirth, we have today's appearance." ”

Bai Xiaofei knows the horror of the corpse brother's fertility, not to mention the mother tree, even the mosquito corpse brother can give birth to a lot of eggs in one breath, and the descendants are tens of thousands, and the fertility of the Xia people is also "excellent", so in a short time, the dungeon is full of Xia people.

Li Shimin said: "Now do you know why we don't repair history, right?" Because the world is changing all the time, and there is no law, you can learn from history and not make mistakes - hum, I see, learning history will die faster! Because this world is not immutable at all! Think you are smart and take the old road, there is only one dead end! ”

Li Shimin clenched his fists: "The only thing we can do is evolve, evolve, evolve!" Before the next disaster, evolve stronger, and then struggle to save a life, this is the only way to save the fire of the Xia clan! ”

Bai Xiaofei was dumbfounded, indeed, the inheritance of history needs a relatively stable environment, in the history of Yan and Huang, there are many great dynasties that have left behind mountains of historical materials, military, economic, people's livelihood, science and technology, and other knowledge, far surpassing other countries in the world at that time.

However, every time a dynasty rises, the tragic war not only kills a large number of people, but also burns these precious knowledge, so that when a new dynasty is born, there is often a fault line and a break in scientific and technological knowledge, and more strictly, there is a regression of knowledge!

In this other world where the Xia people are located, natural disasters occur frequently, and almost every time it is at the level of extinction, in such an environment, it is only hellish that knowledge can be passed on.

If it weren't for the creatures of this other world, such as the Xia people who survived by evolution and relied on the most primordial power to fight against heaven and earth, they would have been wiped out a long time ago. --In other words, if the Earth Yanhuang people survive here, a single poison gas can wipe out all the Yanhuang people every second, just like the dinosaurs were wiped out in an asteroid impact.

However, Bai Xiaofei keenly found an important clue in Li Shimin's words: "Brother Li, you said that before the appearance of Gufeng and the Sour Sea, this world was connected?" Are there other races that have dealings with you? ”

Li Shimin nodded: "If killing and devouring are interactions, they are indeed a way of communication. As far as I can tell from my awakened memories, at that time, it was still an ordinary mountain range—the races and monsters that came to our territory from the lone peak were countless. ”
