As soon as Cheng Yu opened his eyes, the knife was already placed on his neck. He was accused of leaking the secret files of Beizhen Fusi - he became a traitor in the Jinyi Guards who must die, and among the "own people" who will be beheaded in three seconds, there is a real mole. A criminal psychologist traveled through time and became a death row prisoner, but was called out by the commander in public: "Cheng Yu, you come for execution." He could see through the lies, but he had to cut off his colleagues' heads with his own hands and use this bloody drama to fish out the mastermind behind the scenes. When his former inmate knelt down and begged him for help, when his superior placed the Xiuchun knife on the neck of the person next to him, Cheng Yu smiled and wiped off the blood on the knife: "Don't worry, it will be your turn next." Let's see how the guilty minister used his order to break the situation and let the whole snow in Chang'an City fall into his own hands.
