In the 23rd year of Zhenguan (649), the Tang Dynasty was in the later years of Taizong. There was an undercurrent of competition for the throne after Prince Li Chengqian was deposed. The concubines in the harem were connected with the forces of the previous dynasty. As the residence of the palace maids and eunuchs, the Yeting Palace became the hub where all parties' eyes were intertwined. Lin Yanzhi, a student of modern history, died in a car accident while chasing a thief, and his soul traveled into the body of Lin Xiaowan, a 16-year-old fake eunuch. The original owner was sold into the palace by his uncle half a year ago. Because he had not succeeded in purification, he had been working as a young eunuch in Yeting as a "failed purification". There was an undiscovered secret hidden under the three-foot white silk silk around his waist.
