Shen Yihuan, a twenty-first-century livestream sales influencer, dies unexpectedly and transmigrates into the body of a fifteen-year-old girl in the fictional Great Chu dynasty. The original Shen Yihuan was the neglected daughter of a wealthy merchant family. Her stepmother, Madam Li, deliberately suppressed her for ten years, molding her into a timid and unremarkable girl. When her father saw that she had not inherited her late wife's beauty, he lost all interest and arranged for her to marry a distant relative of Madam Li. The original owner resisted, escaped, and jumped into a river to avoid the match. She was rescued by Jiang Changfeng, an eighteen-year-old hunter. Because an unmarried man and woman had physical contact, Madam Li was forced by public opinion to negotiate a hasty marriage between Shen Yihuan and Jiang Changfeng. The wedding took place in less than three days, and the original owner died of a fever on her wedding night.
Upon waking in her new body, Shen Yihuan discovers she has brought her old family home from the modern world as a portable space. This space functions as a sanctuary containing running water, electricity, and natural gas, along with vast stocks of food, household supplies, and promotional products from her previous life. She can mentally store and retrieve items without physically entering the space. Her first priority is survival and reclaiming her dignity. She inspects her dowry, which her stepmother had filled with worthless junk, keeping only one hundred taels of silver and gold-plated copper jewelry. She stores the silver in her space and resolves to recover her mother's original dowry, which was worth thousands of taels.
Shen Yihuan marries into the Jiang family, a household of scholars and farmers led by her father-in-law Jiang Chunsheng and mother Liu Guiying. The family is warm and harmonious, consisting of three sons and a daughter. Jiang Changfeng is protective and kind, having fallen in love with her at first sight. However, tension exists with Jiang Lanxin, the younger sister, who resents Shen Yihuan due to misinformation spread by Ye Qinghe, a neighbor who harbors unrequited feelings for Jiang Changfeng. Ye Qinghe attempts to undermine Shen Yihuan but is firmly rebuffed. Shen Yihuan uses her modern knowledge and the resources in her space to navigate family dynamics, eventually winning over her mother-in-law while keeping her space a secret.
The turning point occurs during Shen Yihuan's return visit to her natal home. She uses a prank stink spray from her space to humiliate her half-sister Shen Mingzhu and expose the cruelty of her stepmother. Taking advantage of the chaos, she breaks into the family storerooms and empties them of gold, silver, jade, silk, and food supplies into her portable space. She also sprays foul odors around her stepmother's and half-brother's courtyards as further retribution. When Madam Li attempts to have her servants attack the couple, Jiang Changfeng effortlessly repels them with his superior strength. Shen Yihuan and Jiang Changfeng leave the Shen residence permanently, severing ties with her abusive family.
Back in Xinghua Village, Shen Yihuan uses her stolen wealth to improve the Jiang family's living standards, purchasing polished rice, flour, and daily necessities. She begins farming in her space, growing crops that supplement their diet. However, strange animal behavior—chickens refusing to roost, dogs barking, and fish leaping from the water—leads Shen Yihuan to conclude that a major earthquake is imminent. She warns her family, but they are skeptical. The story ends with Shen Yihuan preparing for the disaster, relying on her space's abundant supplies while the Jiang family remains unaware of the true scale of the danger she foresees.
