The Queen of Chu, Shen Zhaozhao, was deposed by Emperor Chu Huaijin and sent to the cold palace for three years because she was framed by a noble concubine. During this period, she tolerated the plot, used medical skills to treat people in the cold palace, cultivated her power, and secretly collected evidence of unjust cases. Three years later, the emperor called her back to the palace due to the need to check and balance the court. Shen Zhaozhao appeared to be obedient, but in fact he gradually exposed the concubine's crimes, attacked the hostile forces in the court, and made Chu Huaijin realize his mistake. In the end, she cleared her grievances, took control of the Sixth Palace, and became the most powerful "Queen of the Palaces" in Chu, while Chu Huaijin became her "chess piece" and could only watch her reach her peak.
