Ye Chutang, a divine doctor and martial arts expert from an apocalyptic future, transmigrates into the body of the legitimate eldest daughter of Ye Jingchuan, the Minister of Revenue in the Northern Chen Kingdom. The original host was neglected for fifteen years in the countryside by her father and stepmother, who eventually conspired to drug and assault her before faking her death. Ye Chutang survives the attack, kills her abusers, and discovers she has brought her mystical medical space and earth-based powers with her. While recovering from a poison administered by her enemies, she encounters Qi Yanzhou, a powerful man suffering from a deadly fire poison, and uses him as an antidote. After he recovers and leaves, she decides to return to the capital to reclaim her birthright and exact revenge on her family.
Upon arriving at the Minister’s residence, Ye Chutang confronts her father, Ye Jingchuan, who reveals his true intention: he needs her to take the place of his favored second daughter, Ye Anling, in a marriage alliance with the powerful Chief Eunuch, Lord De. Ye Anling has caught the eunuch’s attention, but the family intends to sacrifice Ye Chutang instead. Ye Chutang agrees to the arrangement only after extracting a substantial financial compensation from her father. She begins to assert her dominance within the household, punishing servants who spy for her stepmother, Kong Ru, and securing the loyalty of her own attendants by offering them freedom from abusive situations.
As she prepares for the homecoming banquet, Ye Chutang uncovers more secrets about the Ye family’s corruption and the political landscape of the capital. She learns that the kingdom is plagued by eunuch dominance and that her father’s rise to power was built on exploiting her mother’s dowry. Determined to dismantle the corrupt system that destroyed her previous life and the original host’s, she plans to use the banquet to expose her family’s crimes while navigating the dangerous politics of the imperial court. Her journey is marked by her strategic use of her medical knowledge, martial arts skills, and the resources within her mystical space to gain virtue points and upgrade her abilities, setting the stage for a confrontation with both her family and the powerful eunuch faction.
