Forensic doctor Jiang Yunyao accidentally traveled through time and became the substitute princess of the cold-faced King Jing Zhou Yanheng. Faced with a series of murder cases in the prince's palace, she repeatedly solved strange cases with her modern forensic knowledge, but this aroused the prince's deeper suspicion. When Zhou Yanheng grabbed her neck and questioned "Xizuo", she smiled and put the dagger into his hand: "If you don't believe me, you can cut open my heart and take a look."
The blade penetrated three points of the flesh, and his hand shook. From then on, a fatal game about trust and truth unfolds. The poisonous weapons in the abandoned alchemy room, the remains of the noble concubine in the Xishan Villa, the shocking conspiracy of the Queen Mother... When all the evidence points to the palace murder more than ten years ago, they are forced to form a life-or-death alliance.
In the whirlpool of imperial power, two people who did not believe in love risked their lives for each other again and again. When the truth was finally revealed in the Xuanzheng Hall, they stood on the white marble steps holding hands, with the shattered conspiracy at their feet and the reconstructed rivers and mountains behind them.
This is a legend about a forensic princess who used her expertise to conquer ancient times, and how she and the cold-faced prince went from murder to fall in love, and together they uncovered the darkest secret of the dynasty.
