The top detective of the Ministry of Punishment arrested Shen Ke, and the investigation found that he was the one responsible - the prime minister had tampered with him, and he was actually the deposed prince who had been framed! The whole city was rounded up by the Forbidden Army, and his former colleagues drew their swords against him. In the desperate situation, he smiled: the nine thousand cases he read in the archives of the Ministry of Justice were the only flaw in this chess game. From the execution officer to the chief assistant, from the murder case in the street to the major case in the court, he used every iron case to solve the problem step by step, turning the evidence of the crimes of the ministers into his own promotion ladder. Until the emperor asked him in a trembling voice, "Who do you belong to?", He leaned over and bowed: "Your Majesty, I am the sword holder of Da Chu."
