Lin Zhiyi transmigrates into the body of a cannon fodder character in a novel, becoming the wife of Qin Lang, a man who used her family's wealth to climb the social ladder. The Lin family, influential in the imperial capital, falls from grace when Lin Zhiyi's father is implicated in a political conspiracy involving the deposed crown prince. Within days of the family's downfall, Qin Lang and his mother plot to demote Lin Zhiyi from wife to concubine so he can marry He Jiaojiao, the daughter of a wealthy official, and seize her substantial dowry.
Upon realizing her fate as a tragic figure who will eventually drive her own family to ruin out of resentment, Lin Zhiyi decides to change her destiny. She discovers she possesses a spatial ability that allows her to store and preserve items indefinitely. Using this advantage, she calmly accepts the Qin family's attempt to strip her of her status and belongings. While appearing compliant, she secretly transfers all her dowry, including land deeds, property contracts, and valuable assets, into her space. She also arranges for her loyal servant, Chai Ya, and her former wet nurse, Fang Mama, to sell off properties and servants before the Lin family's scheduled exile.
Lin Zhiyi learns she is pregnant with Qin Lang's child but decides against keeping it, viewing the child as a link to a toxic past. She induces a miscarriage and prepares for the journey to Fangzhou, where the exiled Lin family will be sent. In the days leading up to the exile, she sneaks back into the Qin residence at night to loot the kitchen, bridal chamber, and bedrooms, stealing food, supplies, and valuables intended for Qin Lang's wedding to He Jiaojiao. She also vandalizes the property, beating Qin Lang and shaving his head, ensuring he faces humiliation on his wedding day.
On the morning of the wedding, the Qin family discovers their home has been completely ransacked. All their valuables, including He Jiaojiao's dowry, are missing. Qin Lang wakes up bald and bruised, while his mother suffers a stroke upon realizing her gold bracelets are gone. The He family's maids, discovering the theft, threaten to expose the Qin family, causing chaos. Meanwhile, Lin Zhiyi has already left the Qin residence, having secured her divorce papers and escaped with her loyal companions. She reunites with Fang Mama and her son, Da Lin, and prepares to join the exiled Lin family on their journey to Fangzhou, determined to protect her family from the fate that befell them in the original novel.
