A blizzard suddenly strikes the south, and successive natural disasters follow one after another. Amidst water and food shortages, city order collapses, and human nature is severely tested in desperate straits. In her previous life, Xiang Yu mistakenly trusted her lover and ultimately died with bitter regret. Reborn in a single lifetime, she returns to the time when the natural disasters first arrive, activates her ancestral storage space, and relies on her five years of survival experience from her past life to fully stockpile supplies, reinforce her dwelling, and build a solid security defense line. She neither actively stirs up trouble nor shows weakness or backs down, holding fast to her bottom line and original intention, and steadily striving for survival amidst the bitter winter and catastrophe. Desperate straits have their own faint light, and the resilience of ordinary people is enough to get through the long night, live well, and ultimately await the dawn when the clouds clear and the snow melts.
