On the day of her divorce, Shen Nanzhi was reborn. In her previous life, her husband’s family schemed to leave her with nothing. Then, when the extreme-cold apocalypse arrived, they locked her outside and left her to freeze to death. Back thirty days before the disaster, she neither cried nor made a scene. She reclaimed her compensation, sold her car to raise money, bought an abandoned cold-storage facility, and stocked up on food and medicine while turning it into a secure shelter. But the cold snap came early. The city lost power and water, and panic buying, mobs at the door, and medicine shortages broke out one after another. Her ex-husband’s family knelt and begged her to take them in, a powerful supplier coveted her resources in secret, and Lu Linchuan, a retired rescue team captain, became her most reliable partner. Then, beneath the Beigang cold-storage facility, a strange voice came from behind a door that had been frozen shut for years. Shen Nanzhi guarded the door and laid down the rules, while gradually discovering that this frozen apocalypse might not be a natural disaster at all.
