Jiang Yuan, a mother who previously died in the apocalypse, is reborn fifteen days before the catastrophic event. In her past life, she and her infant daughter, Xiao Nuan, were abandoned by her cheating husband, Xia Chaoyang, and his mistress, Bai Mengmeng, during a series of extreme weather disasters. They suffered starvation, torture, and ultimately, Xiao Nuan froze to death while Jiang Yuan was assaulted. Vowing to change their fate, Jiang Yuan immediately agrees to Xia Chaoyang’s demand for divorce, but this time she secures the high-altitude Lushan Mountain property, ten million yuan, and child support, leaving him with the house and store burdened by debt. She then embarks on an intense fourteen-day preparation spree, utilizing her knowledge of the impending climate collapse to stockpile resources.
Jiang Yuan reinforces her new apartment with bulletproof glass, multiple security doors, and surveillance systems. She liquidates assets, takes out massive online loans using Xia Chaoyang’s identity, and purchases tons of food, clothing, water purification systems, solar panels, and weapons. She invites her parents to join her, explaining the disaster through a fabricated story about a relative’s research to ensure they are mentally prepared. As the apocalypse begins with temperatures soaring to 50°C, Jiang Yuan’s family remains safe in their fortified home, watching as society crumbles under heatstroke, power outages, and a mysterious blistering skin disease. She monitors her ex-husband and his new family through hidden cameras, observing their initial arrogance turn into desperation.
A key turning point occurs when Jiang Yuan discovers that her neighbor in Unit 2102, a retired soldier named Song Yi, has also fortified his apartment and stockpiled supplies in a manner identical to hers. Suspecting he may also be reborn or possess prior knowledge, she establishes a cautious alliance with him. Together, they lock the stairwell entrance to prevent intruders and share information about the growing dangers, including mutated insects and violent neighbors. When Xia Chaoyang and Bai Mengmeng, now neighbors in the same complex, face starvation and attempt to beg Jiang Yuan for food and fuel, she coldly refuses and confronts them publicly, revealing their infidelity and illegitimate child to the community. The story follows Jiang Yuan’s strategic survival as she navigates the early stages of the apocalypse, protecting her family while ensuring her enemies face the consequences of their actions without her intervention.
