Return to the Primitive Tribe to Farm and Rise

"If I go back to the primitive tribe, I will farm, make pottery, metallurgize, and build a powerful human kingdom!" When Su Geng walked out of the cave and looked at the thousand-meter snow wall that reached the top, he couldn't help but doubt his life. "Except for the Ice Age!" Extreme cold, physical shortages, threats from giant beasts, disease erosion, habitat loss... Just when the primitive tribe was about to perish, Su Geng traveled through the country, only to find that the glacier was about to burst, the lake was about to collapse, and there was not much time left for the tribe. In order to protect themselves, they made fire in the cold winter, hunted under the ice, polished stone tools, and surrounded and killed ferocious beasts... "Wait a minute! This primitive tribe doesn't seem very primitive!" PS: Pure original farming writing, so pure~
