Shen Zhiwei, the legitimate daughter of the Shen family, was afraid of having children, so she happily accepted the imperial edict to marry the nine-thousand-year-old eunuch Pei Xuan. Her family was heartbroken, but she was the only one who was secretly happy. At the palace banquet, she stood up for Pei Xuan, but was involved in his power dispute. The secret of Bizitang was also exposed, and the relationship between the two went through many twists and turns. Shen Zhiwei gradually got a glimpse of Pei Xuan's plan to change the dynasty, and chose to fight alongside him to help him quell the palace coup. In the end, Pei Xuan helped the young emperor ascend the throne as regent, and Shen Zhiwei became regent concubine. Pei Xuan fulfilled his promise not to force her to have children. The two stayed together and looked forward to a stable life in the south of the Yangtze River in the future.
