In order to save her family in prison, Shen Qingzhu, the daughter of the guilty minister, was forced to take over her identity as the prime minister's legitimate daughter and marry the rumored violent and terminally ill emperor Xiao Jue Chongxi. On the night she entered the palace, she discovered that the emperor was not really ill, but was keeping a low profile. In order to survive, she made a deal with the emperor and became his "sword" in the harem, protecting him from love affairs, fighting against powerful ministers, and slandering the emperor. Without any golden fingers, Shen Qingzhu relied on his extraordinary insight and unique skills of imitating handwriting to save himself from danger time and time again in the cannibal harem. The two went from using each other, testing their defenses, to fighting together, and even calculating each other's sincerity. In the end, they eradicated their relatives and powerful officials. Shen Qingzhu not only cleared the family's grievances, but also gradually ascended to the throne of Phoenix, dominating the Sixth Palace alone.
