The story begins with a scorching heat that has never happened in a century. The water level of the river dropped sharply and everything withered. Su Wanqing, a herbal picker who is proficient in pharmacology, relied on her keen observation to foresee that a catastrophe was coming, and began to quietly sell off her property and hoard supplies. In the process, she met Gu Qinghan, the female shopkeeper of the largest grain store in the city, a widow known for her coldness and shrewdness. Gu Qinghan initially scoffed at Su Wanqing's "alarmism", but after witnessing the increasingly bizarre celestial phenomena and people's panic, Gu Qinghan chose to believe in Su Wanqing with his extraordinary business acumen and judgment of the current situation.
From the initial mutual testing and profit cooperation, the two were forced to join forces when natural disasters (scorching heat, blizzards, floods, and plagues) came one after another. Su Wanqing used her medical knowledge and wilderness survival skills to solve the team's survival and health problems; Gu Qinghan used her excellent management skills and deep insight into human nature to build a shelter, formulate rules, and lead the survivors to carve out a peaceful land in the apocalypse. They have no golden fingers, their only weapons are each other's minds and hands. In the tests of life and death, the two sublimated from partners to each other's only reliance and love. They jointly fought against natural disasters and human hearts that were more terrifying than natural disasters, and finally built a new home that could protect all living beings.
