Li Feng unexpectedly travels back to the Stone Age and arrives in a backward tribe of ape-men. Without any special powers or cheat abilities, he can only use his own intelligence to change his fate. Starting with a simple hemp rope, he gradually introduces fire, farmland, pottery, and iron tools, kindling the spark of civilization in the wilderness. While everyone else is still struggling to discover how to survive, he has already led his tribe toward a new era. Years later, what he has created is more than just a tribe—it is a legend that changed the history of the primitive world.
