Divorced on Her Wedding Night the Physician Secretly Marries the Crown Prince

Lan Shuang, a modern inheritor of traditional Chinese medicine, transmigrates into the body of a noble bride on her wedding night. The original host had died of fury after discovering her husband, Ji Yunqian, and the Fifth Princess were together. Rather than accepting a humiliating fate as a concubine, Lan Shuang writes her own divorce letter and uses her ancestral medicinal space to administer a powder that renders the couple infertile and incapacitated for a day. She then systematically loots the marquis estate, the national treasury, the imperial palace, and the empress’s chambers, securing enough wealth to sustain her family. The Duke of Zhen-guo’s household, her natal family, is subsequently confiscated by the new emperor due to political suspicion, forcing the women and children into exile.

Returning to the devastated estate, Lan Shuang chooses to stay with her grandmother and sisters-in-law rather than flee alone. Her twin brother, Lan Shan, is sentenced to exile in the northern lands after protesting the emperor’s decree. Before he departs, Lan Shuang treats his severe injuries with advanced medical techniques, revealing her hidden talents to the family. Meanwhile, Lan Shan’s fiancée, Zhou Ru-yan, sends a maid to break off the engagement, citing the family’s fallen status. Lan Shuang retaliates by secretly administering an allergic powder to Zhou Ru-yan, ensuring her face suffers for months as punishment for her cruelty.

The exiled family travels to Xu Family Village, the ancestral home of the second sister-in-law, Xu Shi. There, they discover that Xu Shi’s uncle and aunt have illegally occupied the house. Lan Shuang confronts the relatives, using the threat of legal action to force them to vacate. With the house secured, Lan Shuang assumes the role of household manager, devising plans to earn income through selling food recipes and practicing medicine. She balances the needs of the elderly, the pregnant, and the young child, Lan Su, while maintaining a low profile to avoid further persecution by the emperor’s agents.

Ji Yunqian eventually tracks the family down, attempting to lure Lan Shuang back with promises of restoring her status. She rejects him outright, asserting her independence and refusing to return to a life of subservience. The narrative follows Lan Shuang’s efforts to rebuild the family’s fortune from scratch in a rural setting, utilizing her medical skills and strategic mind to navigate the dangers of a political exile. As she establishes a legitimate source of income, she prepares to support her father and brothers who remain at the border, while keeping her true capabilities and hidden wealth concealed from those who would exploit them.
