[Rebirth + Primitive + Farming + Primitive Life + Empire Building + Ushering in a New Era] Lin Ye, an outstanding graduate of an agricultural university in the 21st century, accidentally falls off a cliff during a wilderness expedition. His soul transmigrates into the body of a recently deceased young man of the same name in the "Flame Stone Tribe," a primitive tribe living in the Stone Age. Arriving at the brink of collapse, he uses his modern knowledge to gradually lead the tribe to stability, starting with making fire, producing salt, and building shelters. He improves tools, develops agriculture and animal husbandry, explores unknown territories, transforming a precarious small tribe into a powerful city-state, ultimately creating his own primitive empire.
