Under the prosperous scenery of the Yu Dynasty, there was a deep undercurrent. It seemed that the world was peaceful and the people lived in peace, but in fact, it was rotten inside, with corrupt officials running rampant, officials protecting each other, and the imperial power being unbridled. The people were in dire straits and miserable.
Xie Jingyun, the newly appointed Shaoqing of Dali Temple, has a righteous heart and is determined to clear up the injustice; the genius doctor Lu Yunzheng has superb medical skills and is good at solving the mysteries of life and death; Liang Zhen, the killer of the dark pavilion who has a blood feud, is cool and decisive, and has a hidden edge. The three of them met unexpectedly at Youmeng Villa, and the threads of fate intertwined since then, forming an iron triangle for investigating the case.
Unexpectedly, the three of them have already stepped into a huge and secret chessboard. Once the chess pieces have fallen, the situation has suddenly changed. From this moment on, it is difficult to turn back their fate. Only by breaking out of this treacherous chess game can they find a chance of survival, restore the Yu Dynasty's innocence, and relieve the people from hanging upside down.
