The Caveman Made Me Awesome

Rebirth into the primitive society, is it unexpected or surprised?

Ye Xi was born again, but in his heart there were ten thousand grass and mud horses galloping.

Giant insects of the Carboniferous, dinosaurs of the Jurassic, and fierce beasts of the Paleogene, which primitive age is this time and space?

Are humans so weak? What about rebirth benefits?

No way, Ye Xi could only bring primitive people and sound the clarion call for the rise of the primitive world!

Primitive: Ooooooooo amazing, my brother!
