Not trapped in the back house, not confined to the palace wall, and not competing with each other, three vested female thieves (female strongmen) fought for freedom: Tang Yi, the number one killer in Qianji Pavilion and the tool of the seventh prince Li Zhaohe, decided to break away from the control of Li Zhaohe who was about to get married, get rid of the fate of killing and involuntarily, and quietly plotted. Tang Jiu, a female assassin from Qianji Pavilion, failed in her assassination mission, her identity was exposed, and was silenced; Nie Shisan, a female hair thief and flower-picking thief, made a mistake while stealing wealth, angered the big shot, and was hunted down by the big shot. Tang Jiu came back from the dead, and his body was filled with Feng Keyan, a playboy who had traveled from the 21st century, and was therefore bound to Tang Yi's life and death. In order to save his life, Tang Yi accepted the mission and went to Qi State, and quietly asked Tang Jiu to pretend to be a princess. Nie Shisan accepted Mr. Meng's mission to save his life, deliberately approached Tang Yi, and sneaked into the princess's wedding party. The three people who escaped were separated due to differences on the way. When the world was in chaos, their hidden identities were exposed one after another. They finally cooperated with each other to seek a glimmer of hope in the competition between various forces.
