Modern girl Apu arrives in a primitive matriarchal wasteland, where women are brave, hold power, hunt, and defend their territory, while men are gentle and skilled in household affairs and medicine. After awakening a survival system, she first leads the entire Blackstone Tribe to escape a deadly beast stampede and finds a mountain-surrounded valley to settle in. She then conquers the Red Fang Tribe, which stubbornly upholds male dominance, abolishes its old customs, and promotes equality between men and women. Facing one crisis after another, including droughts, locust plagues, flash floods, wolf packs, and raids by outsiders, she pioneers farmland, digs wells, builds houses, constructs irrigation channels, and establishes a complete tribal system. She wins over her opponents through virtue, tames the Wolf King of the wasteland, and eventually succeeds her mother, Liege, as chief with her support. Through wisdom and responsibility, she protects countless tribespeople and creates a peaceful and prosperous home in the wasteland.
