Under the lonely sword blade of Hidden Sword Villa lies a blood-stained past on the palace wall. When Yu Jinghong grasped the "Guhong Sword", she not only grasped the pride of the world left behind by her mother Yu Qingluan, but also grasped a blood-red oath that spanned fifteen years - to repay all blood debts to the queen who lived in the deep palace, and to the Nine-Five Lord who had promised her mother a stable life.
The grievances of the world and the blood of the palace are intertwined under her sword: the master Li Subai hesitates to speak while looking at the sword of the deceased senior sister, the uncle Yu Fuling is secretive about Beijing's past, and the sister named "Xiao Jinxue", the target of every assassination mission is vaguely pointing to everything she protects. When she thought the road to revenge was directed at the palace, she discovered that she was already the sharpest pawn on the chessboard of power - Meng Zhaoting regarded her as the blade that broke the situation, and the queen regarded her as a trouble that must be eliminated. And is she herself a lonely person avenging her mother, or a variable that stirs up the world?
Where the sword rises, the swans startle in the sky; the blood is cold, and grudges are hard to settle. This is a revenge epic about a girl who bears a double fate. It is also a long and cold song about a lone sword that cuts through the truth and conspiracy in the gap between the rivers and lakes and the court. When twin flowers bloom at both ends of light and dark, who will be the sword light that finally pierces the long night?
Purpose: The girl breaks the fateful puzzle with her sword, and the hatred between twins illuminates the machinations of the world.
