Ancient Invasion [End Times]

The 180th and seventh day after the invasion Bi Fang, Bi An, Ba Xia's prehistoric events

Following the explosion of Cambrian life, a famous paleontologist Gould proposed the famous "interrupted balance theory".

In layman's terms, evolution and the emergence and mutation of new species occur in the intersection of marginal species where the pressure of survival is greater and the environment is harsher and more complex.

This theory complements Darwin's theory of evolution perfectly.

——The evolution of organisms is not entirely gradual accumulation, but the alternation of gradual and leap forward.

Cheng Sheng, Duan Yi and Ba Xia were born under such circumstances.

Not just them.

Cheng Sheng still remembered that in a very long time ago, the land was a completely different scene from the present.

Huge prehistoric creatures abound, their territories spanning water, land and air.

The carnivores prey on the weak and the weak evolve. It is a wild world where the weak and the strong prey on the strong.

Until the mass extinction of creatures came, the global temperature changed suddenly, and more and more dead creatures appeared on the continents and seas, and only a few survived. They evolved, mutated, and gave birth to new species.

There have been five mass extinctions in total, and there are only a handful of surviving creatures. They follow their instincts and hide deeper in the earth.

The surviving organisms undergo qualitative leaps and mutations under the continuous catastrophe, and the living organisms evolve a self-protection defense loss mechanism.

Cheng Sheng met Duan Yi and Ba Xia at that time.

The ancients described their footprints in the Book of Mountains and Seas, but even Cheng Sheng didn't know if the creatures described in that great book were them.

Bi Fang is not the name of a creature, but the name of an ethnic group, the same is true for Ba Xia and Bi An.

It's just that the three of them have lived longer than others of the same race, and they are even more different.

When the three of them met, there was no concept of "name".

Three big fellows of different races, one occupying the sky and two occupying the land, Cheng Sheng just flies in the sky every day to watch Baxia and Bi An fight.

One has the hardest shell in the world, and the other has the sharpest fangs in the world, neither of them can break through the other.

In the end, for some reason, one professional eating melons and two professional fighters became three good friends.

Abbreviation, Live and See Combination.

Alias, can't die group.

Ba Xia loved to hunch things on his back since he was a child. When he was young, he hunched on stones, branches, and small snails. Later, after getting to know Bi Fang and Qu An, the things on his back became bigger and bigger. First, he started with the prey they caught. Later it was Bi Fang who was too lazy to fly, and later even the dog Bi An lay on his back.

——Ba Xia once turned himself upside down in order to throw Bi An out of his shell, but in the end it was Bi Fang and Bi An who worked together to turn Ba Xia back on his back.

The three big animals are happily isolated from the world. They have lived for an unknown number of years. They play with birds and beasts every day, fight and watch dramas, or go to the "big pool" to take a bath together. I don't know how their small lives are. How comfortable.

Until one day, a group of people broke into their living area, and then retreated quickly as if frightened.

Ba Xia didn't care about this, but Bi Fang and Bi An became curious, and it was the first time they saw such a "two-legged beast" walking independently on two feet.

So one bird and one beast decided to find out, but Baxia didn't follow because he was too lazy.

When Ba Xia saw Bi Fang and Qu An again, both of them also turned into two-legged beasts, wearing strange "fur" on their bodies, appearing strangely in front of them.

Baxia felt that it could swallow dozens of these scorpions in one gulp.

Bi Fang and Bi An shared what they had seen and heard along the way with Baxia, but Da Gui began to fall asleep halfway through listening to it—to tell the truth, Bi Fang and Bi An were really not suitable for storytelling, it was dull and tasteless No ups and downs.

For Ba Xia, who was also not a good listener, Bi Fang and Bi An exchanged glances, hit it off, and ran out again when Ba Xia was drowsy.

They are inseparable, staying in the human world, wearing human clothes, secretly learning human rules and languages, and eavesdropping on the joys and sorrows of the human world.

"Have you eaten?" - Ba Xia was quite speechless when he heard Bi An and Bi Fang standing in front of him, blinking his eyes, showing off the first sentence of language he learned from the human world.

That's it?That's it?The first sentence I learned was to ask people if they ate it?

Domineering eyes.

Of course, it was more than that, but Baxia had no chance to hear it.

Bi An and Bi Fang settled in the human world, playing roles round after round——

Occasionally there are two brothers who depend on each other, one is a poor and elegant scholar, and the other is a leader in martial arts;

Or one became the owner of a pawn shop, and the other went to the police station as a detective.

They always disappear every few decades, go where no one has seen them, and start a journey anew.

It was at this time that Bi Fang and Qu An had their own names.

The two of them passed by the stall of a blind celestial master and were stopped by the blind celestial master.

That day, the master muttered, "You two are rare, with precious fates. I don't know what their surnames are?"

"No name, no surname, he and I were born together." Bi Fang said.

When the teacher heard the words that day, he calculated a name for the two of them.

Bi Fang named Cheng Sheng.

"The character of sound belongs to gold, and it is recorded in the fate book. If strong gold gets fire, it will become a famous weapon." The blind celestial master shook his head slightly and said, "There is a couplet in the ancestral hall of the surname Cheng. For the surname, it is Jipei."

The celestial master turned to Duan Yi again, squinting his eyes: "The word Yi belongs to wood, and wood makes fire. You and his fate are related to each other. Would you be willing to give you the character 'Yi'?"

Bi An nodded without hesitation and cupped his hands, solemnly answering the word.

Bi Fang, who changed his name to Cheng Sheng, squinted his eyes, turned his head to look at Bi An, raised the corners of his mouth, and his eyes were bent into moon hooks, making Bi An's heart palpitate.

Baxia would come to "visit relatives" occasionally, but Baxia's human form was not well cultivated, the huge turtle shell was always buckled behind his back, so that when Baxia came over, he didn't pretend to be the old father of the two, It was brought by Bi An, who was locked in a crystal glass and shrunk down to look like a money turtle.

In contrast, Ba Xia prefers Bi Fang and Bi An to call him father.
