A modern adult accidentally crosses over into the primordial wilderness, possessing the body of a fourteen or fifteen-year-old youth! Ferocious beasts run rampant and natural disasters are constant, with a weak tribe struggling on the edge of life and death, wrapped in animal skins and drinking blood. Armed with modern knowledge, he descends to make pottery, reclaim fields, mine and smelt copper, and build defensive fortifications. He resists the invasion of fierce beasts, endures floods and cold snaps, and repels invading hostile tribes. Starting from a small stone stockade, he pioneers the land, builds order, and step by step constructs a magnificent city-state. The spark of civilization illuminates the great wilderness, surrounding tribes submit one after another, and ten thousand clans come to pay homage! Watch him use mortal wisdom to create a brilliant civilization on the wilderness earth!
