Lin Xizhi awakens on a passenger ship in 1968, realizing she has been reborn to the day before her death in a previous life. In that past existence, she was betrayed by the Pei family, who were entrusted with her inheritance by her late father. They drugged her during a pirate attack, handed her over to sea robbers, and later imprisoned and tortured her to steal her mother's wealth. Pei Yuncheng, the man she loved and considered her fiancé, locked her in a basement and watched as his mistresses burned her alive. Upon waking, Lin Xizhi discovers she has returned to the moment the Pei family attempted to sacrifice her to the pirates to save their own skins. She also finds that the black-and-gold ring she wore in her previous life has transformed into a mysterious spatial ability, allowing her to store and retrieve objects.
Instead of remaining a victim, Lin Xizhi uses her knowledge of the future and her new spatial powers to reclaim her family's stolen treasures. She secretly empties the cargo hold of the Pei family's belongings, including gold, jade, and valuable furniture, into her storage space. When the Pei family attempts to hand her over to the pirates, she is rescued by Song Zhuowei, a captain of the Sea Guard. In her previous life, Song Zhuowei had saved her but remained a distant figure she never truly connected with. This time, she recognizes his integrity and decides to align herself with him. Song Zhuowei, initially stern and focused on duty, becomes increasingly protective of her after discovering she was drugged with a substance meant to stimulate animal mating urges.
The Pei family, having lost their stolen wealth to the pirates and now exposed as capitalists attempting to flee to Hong Kong, are arrested and assigned to Shajing Commune as educated youths. Lin Xizhi also receives this assignment but strategically chooses to stay with Aunt Hui, a reclusive and skilled herbalist in Widow Village, rather than living with the other educated youths. Aunt Hui, who had trained Lin Xizhi in medicine in the previous timeline, agrees to take her on as an apprentice. This arrangement allows Lin Xizhi to recover her health using the spiritual spring water in her storage space while staying close to her master. Song Zhuowei, despite his gruff exterior, ensures her safety and facilitates her placement, though he is unaware of her true intentions and past-life memories.
As Lin Xizhi settles into her new life, she uncovers that the Pei family had been poisoning her for years under the guise of nourishing soups, causing her infertility. Aunt Hui detects the poison and begins treatment, revealing the depth of the Pei family's cruelty. Meanwhile, Song Zhuowei's grandmother, Grandma Song, takes a keen interest in Lin Xizhi, hoping to marry her to Song Zhuowei to continue the Song family line. The story follows Lin Xizhi as she navigates the political and social landscape of the commune, rebuilds her health, and plans her revenge against the Pei family, all while developing a complex relationship with Song Zhuowei. The narrative sets the stage for her transformation from a victim into a powerful woman who controls her own destiny, leveraging her spatial abilities and medical skills to outmaneuver her enemies.
