The soul of a modern ace agent travels to Xiao Yi, the prince of the fallen Ming Dynasty. As soon as he opens his eyes, he is trapped in the Caishikou execution ground. He is framed by the traitor Zhao An and Xin'an Hou Zhao Gaofei and is about to be cut in half and executed. In a desperate situation, the secret spy system was bound and activated. He escaped from death with a fake death pill and transformed into Chen Mo, the jailer of Dali Temple, to seek revenge.
He used his insightful eyes to detect conspiracies, use the art of disguise to change his identity, outwit the Marquis of Xin'an, solve a series of murder cases, instigate rebellion against the prime minister's cronies, and stir up trouble in the court every step of the way. From a death row prisoner to a military supervisor, from a jailer to a spy network, Xiao Yi used secret agents to subvert the power of the traitor, uncovered the secrets of the Shanhe State Map, and restarted the Ming Dynasty spy legend in troubled times.
