Cheng Zhizhi was once the top dead man in the purgatory "Lejin" who struggled for ten years. Only by falling off a cliff did he earn a chance of survival from the sea of blood and corpses.
She thought that death would be her liberation, but she was picked up from a mass grave by Shen Jinye, the Nine-Five Lord, and a piece of poison was inserted into her throat. From then on, her life and death were in the hands of the emperor.
In order to survive, she was willing to become a substitute and traveled to northern Xinjiang as Su Wanyin, the daughter of Jing'an County Magistrate, and sneaked into the mansion of the acting king Shen Jinsheng to work as an undercover agent.
One is a sinister and ruthless emperor who regards her as a sharp blade, and the other is a cold and sharp vassal king who can see through her disguise at a glance.
A chess game of fratricide between brothers completely involved her in the center of the storm.
In the heavily guarded Daijiang official residence, she worked step by step, hiding her edge, detecting defenses, and discerning eyes. She relied on her secret agent instincts engraved in her bones to survive in the cracks of all forces.
She originally just wanted to complete the task, exchange for the antidote, and wait for an opportunity to escape, but through repeated trials and confrontations with Shen Jinsheng, she discovered the secret past behind her identity, and also moved her heart that she shouldn't have.
When the chess pieces no longer want to be manipulated by others, when the sharp blade has its own desires,
Who will decide the outcome of this chess game in which the world is at stake and life is at stake?
Intention: Even if you are trapped in a prison and your life is like a piece of grass, you will not be willing to be a pawn.
