Agricultural agronomy PhD Lin Wan died suddenly from experimental overwork, time-traveling back to the primitive era to become an "evil woman" about to be drowned in a pond as a sacrificial offering. The down-and-out hunter A Ye bravely stepped forward to save her. Relying on modern knowledge to make fire by drilling wood and gain a foothold, she cleared land and grew crops, made salt and wove cloth, built walls and trained soldiers, tore apart the witch's divine power fraud with her own hands, repelled the invasion of a large tribe, pushed A Ye all the way from a down-and-out hunter to the position of tribal chief, and further exposed the mastermind behind the high priest, leading the tribe to ignite the dawn of civilization.
