Before the Exile, the Substitute Medical Consort Emptied Her Nemesis's Storeroom

Su Banxia, a high-ranking disciple of the Heavenly Palace and beloved student of Taishang Laojun, is cast into the mortal realm as punishment for intervening in a dispute between the Jade Emperor and Chang'e. She transmigrates into the body of a ten-year-old girl with the same name, who was bullied by her stepmother Hu Peilan and cousin Hu Guangfa before dying by suicide. Upon awakening, Banxia immediately asserts her dominance, using divine power to punish her abusers and rejecting the submissive role assigned to her by the original story's plot. The narrative establishes that she is aware this world is a fictional novel written by the Hundred-Flowers Fairy, and she intends to rewrite her fate rather than follow the tragic script designed for the original protagonist.

The central conflict arises from Banxia's forced marriage to Prince Yu, Fu Lingxiao, a royal figure known as the "Foolish Prince." The Su family, specifically her father Su Ya'an and stepmother, have schemed to strip her of her dowry and betrothal gifts, intending to give them to their own daughter, Su Mingzhu. Banxia counters these schemes by secretly using her phoenix egg space and divine beast to empty the Su family's warehouses of all valuables, replacing them with trash. She also secures a substantial cash dowry from the family patriarch, Grand Secretary Su, by threatening to expose the family's secrets to the Emperor. Her actions disrupt the original plot, triggering warnings from a robotic system that attempts to enforce the story's trajectory, which Banxia openly defies using her divine artifacts.

Key turning points include Banxia's wedding night and her subsequent assertion of authority within the Prince Yu manor. Upon arriving, she discovers that Prince Yu is not truly foolish but possesses a childlike innocence and hidden capabilities. He reveals that he had a dream of her, suggesting a connection beyond the current timeline. Banxia quickly establishes her rule over the manor, physically defeating the old Princess Consort's guards and servants to demand respect. She takes charge of the household finances and staff, marginalizing the old Princess Consort and her daughter, Princess Hejing, who initially oppose her. Banxia's boldness extends to the imperial court, where she refuses to kneel before the Emperor and Empress Dowager, causing a miraculous lightning strike that validates her divine nature and unsettles the royal family.

The story progresses with Banxia and Prince Yu navigating political intrigues and personal vendettas. Banxia exposes the affair between Su Mingzhu and Fu Heng, the heir to the Rong Prince's residence, which leads to the cancellation of Su Mingzhu's engagement to the Crown Prince. This act of sabotage further derails the original plot and humiliates the Su family. Banxia continues to plunder the Su family's remaining assets, including the secret stash of her father and the illicit affairs of the matriarch, leaving the family in ruins and disgrace. The narrative highlights her ruthless efficiency and lack of sentimentality, as she systematically dismantles every obstacle and enemy while enjoying the material comforts of her new life.

The story direction follows Banxia's integration into the royal family while maintaining her independence and divine power. Prince Yu becomes her devoted companion, eager to please her and protect her, though his true nature remains ambiguous. Banxia plans to empty the Prince Yu manor's treasures before the scheduled exile, ensuring she gains maximum benefit from the upcoming disaster. The tension between her desire to return to the Heavenly Palace and the constraints of the mortal plot creates an ongoing struggle. As the Su family faces confiscation and exile, Banxia stands as a formidable force who has turned the tables on her oppressors, setting the stage for further conflicts with the imperial court and the original characters of the novel.
