Su Wantang, the legitimate daughter of the original wife of the Su Mansion, was criticized as a bad luck star when she was born. Her biological mother died because of her, her father despised her, her stepmother encouraged her to kill her, and she was exiled to Zhuangzi to fend for herself. Ten years later, a marriage contract called her back from the dust - to replace her beloved stepsister and marry the unconscious and dying prince of Zhenbei. Everyone was waiting to see the joke of her becoming a widow and being buried. However, this was the only way out for Su Wantang who had been dormant for many years and took the initiative to find a way out for himself. She uses the "disaster star" as a shield, the contempt of the world as a cover, and the photographic memory and wisdom of insight into human nature as a blade to deal with the crisis-ridden palace and the Su family, surrounded by tigers and wolves. She defeated her stepmother's evil plan, purged the evil spirits in the court, rescued the prince, and took advantage of the situation to rise up. Eventually, she liquidated the hypocritical family, greedy relatives, and even the forces in the court that regarded her as a pawn. She transformed from an "evil star" that everyone could bully into a behind-the-scenes person in charge of the central government and influencing the affairs of the court. She shared the power with her husband who stood side by side.
