The "Case Solving Manual" in his left hand provides insight into the evidence, and the flintlock gun in his right hand cleanses the traitors with blood.

Above the court, he was the sharpest knife in Emperor Jiajing's hand; far away in the rivers and lakes, he was the "Marquis of Zhenhai" whom all people knelt down to worship.
