Su Wanyi, a top modern surgeon, accidentally travels through time to a snow-covered village during a devastating famine, becoming a poor young bride whose husband disappears just three days after their wedding. With the family out of food, the village chief, Zhang Fugui, fabricates a grain-tax debt and forces her to remarry to pay it off. At her most desperate moment, Su Wanyi awakens a mysterious space, using its supplies, modern combat skills, and business acumen to slay snow wolves, trade for food, rescue Li Yue, and protect her younger brother-in-law, Lu Yan. Step by step, she exposes the schemes of Zhang Fugui and his son, rebuilds her home, and develops a greenhouse business. Years later, Lu Yan and Li Yue both become successful, while her husband, Lu Yuan, who had been missing for years, suddenly returns.
