In an accident, she fell from the reinforced concrete city into the ancient wasteland where hair and blood drank. Without the blessing of the system and no superpowers, only the remaining modern knowledge in her mind and the survival instinct in her bones became her only weapon against the wilderness. There are ferocious beasts with exposed fangs circling day and night, moody natural disasters that can strike at any time, the dilemma of scarcity of resources, and the unfamiliar rules and potential hostility of primitive tribes. She learned to identify edible plant roots, polished rough stone tools, built a simple shelter that could withstand wind and rain, and used the dim light of drilling wood to make fire to dispel darkness and fear. When getting along with the tribesmen, she must not only resolve the suspicion caused by cognitive differences, but also use wisdom to deal with internal disputes over interests; she must not only learn hunting skills from the tribesmen, but also try to pass on the simple farming concepts. From struggling to survive alone to integrating into a tribal group, from avoiding danger to proactively responding to crises, every step is full of thorns and sweat. She is not born strong, but she grits her teeth and perseveres in desperate situations; she does not seek to change the ancient structure, but only seeks to earn a stable livelihood and hope of survival for herself and the people she trusts around her on this vast land. In this primitive and magnificent land, she dug for life with her hands, fought against fate with tenacity, and wrote an ancient survival legend for ordinary people.
