World-Shattering Crisis: I Built a Peach Blossom Utopia in Ancient Times

Yu Nuan, a woman suffering from severe stress and bipolar disorder in her modern life, dies in a traffic accident and transmigrates into the body of a sixteen-year-old girl with the same name in an ancient rural setting. She awakens in a dilapidated mud-brick house to find an elderly woman, Yu Mother, in active labor at nearly sixty years old. With no medical assistance available and the father, Yu Father, absent, Yu Nuan must rely on her limited knowledge and instinct to deliver the baby. She manages to start a fire, assist in the birth, and care for the newborn, whom the family names Gou Wang, a humble name intended to ensure the child's survival. The family is impoverished, living on the edge of starvation with barely any food or resources.

Shortly after stabilizing the immediate crisis, Yu Nuan discovers a "starter gift pack" in her mind, a system that provides her with medical supplies, food, and other essentials. This golden finger becomes her primary tool for survival. She uses the medical kit to treat her own head wound and the provided goat milk powder to feed the newborn, as Yu Mother is too old and weak to produce milk. Recognizing the dire poverty of her new family, she decides to take charge of their livelihood. She ventures into the nearby mountains to forage for wild vegetables and hunt, successfully killing a large black-tailed snake and capturing wild rabbits, despite being bitten by the snake in the process.

Yu Nuan trades the snake meat with villagers in exchange for grain and seeds, securing a more stable food supply for the family. She also uses her system's search function to identify edible plants and learn survival techniques. Back home, she improves their living conditions by creating wind chimes to deter birds from their small garden plot and preparing nutritious meals with the food she procures. Her competence and sudden change in demeanor surprise the elderly Yu Father and Yu Mother, who are accustomed to her previous passive nature.

The family's peace is disrupted when Zhang Xiufang, the wife of Yu Nuan's eldest brother, arrives with her daughters-in-law. They demand that Yu Nuan marry off to a wealthy but flawed bachelor, Wang Jinlong, in exchange for a small bride price. Their true intention is to remove Yu Nuan from the household to avoid supporting her and the new baby, while also trying to claim any benefits for themselves. When Yu Nuan refuses and exposes the flaws in the proposed match, Zhang Xiufang becomes violent, attacking Yu Father and attempting to harm Yu Nuan. In self-defense and to protect her family, Yu Nuan overpowers Zhang Xiufang, choking her until the woman's daughters-in-law flee in terror and call for help.

As villagers gather to witness the scene, Yu Nuan stages a fake injury on her forehead to appear as the victim of a brutal assault. This strategic move shifts the narrative, forcing the villagers to intervene and protecting her from retaliation. The confrontation establishes Yu Nuan as a formidable figure who will not be bullied. She continues to manage the household, using her system to heal injuries and provide nutrition, while planning to expand their agricultural efforts. The story follows her efforts to build a sustainable life for her family in this harsh environment, balancing the challenges of poverty, family dynamics, and the secrets of her mysterious system.
