During the Qianlong period, Shen Zhaoxue, the daughter of Suzhou weaver, entered the palace to clear away her family's grievances. She is as gentle as water but has hidden agendas. In the turbulent Changchun Palace, only the sharp-edged palace maid Wei Yingluo forms a life-or-death alliance with her.
Within the red wall, they are each other's sharpest sword and toughest shield. Zhaoxue is strategizing behind the scenes, while Yingluo is breaking things off and paving the way in front of the stage. From the Embroidery Workshop to the Golden Palace, the two sisters join forces to punish the traitor and break the mystery, vowing to fight their way through the cannibalistic Forbidden City.
When the dusty truth is revealed one by one, when friendship goes through the test of life and death. She is willing to use her lifelong strategy to help her break free from the prison and fulfill her lifelong love with Fu Heng. And what is left at the top of the palace of this great dynasty is an eternal legend about protection, revenge and transcendent love between men and women.
