Modern wilderness survival expert Lin Ye accidentally time-travels to the cruel Stone Age, becoming the "witch" of the weak Fire Tribe. Facing the threats of hunger, wild beasts, and hostile tribes, he relies on modern wisdom to refine white salt, fire pottery, domesticate animals, practice agriculture, and build slings and bows. He unites his clansmen, builds sturdy city walls, resolves the winter crisis, defeats fierce surrounding tribes one after another, and absorbs displaced weak tribes. From struggling to survive to developing agriculture and animal husbandry, Lin Ye leads the Fire Tribe to break through the barbaric dilemma, writing a legend of civilization rise belonging to primitive tribes above the wilderness.
