Modern college student Shen Luxi time-travels and becomes a deposed consort who has been cast into the cold palace for three years. The moment she opens her eyes, she receives poisoned wine sent by the Empress. Wanting her to die a dignified death? She insists on carrying an empty wine bottle and storming the Fengyi Palace, using her mouth and a stack of account books to tear open the dark secrets of the inner court and overthrow the Empress. After gaining the appreciation of Emperor Zhou Mingyuan, she goes from a deposed consort in the cold palace to a court attendant, investigating bribery cases, breaking up conspiracies, and rebuffing imperial concubines, while effortlessly turning the inner court's rules upside down. But when the Empress Dowager's decade-long layout forces a palace coup to seize the throne, Shen Luxi has no choice but to join forces with the Emperor to fight back. She originally wanted to leave the palace and lie flat, but in the end, she is conferred as the Eldest Princess. In this inner court, she won, and she can finally turn around with flair.
