On a rainy night, Lu Xiao personally buried the witness Qi Jin in the mud, just to cover up a shady story that could overturn the entire top police force. Ten years later, Qi Jin returned from the bloody process and sat in the dock as a witness to expose Lu Xiao's crime of silence. The whole police station was in an uproar, but Lu Xiao had no expression on his face. He only whispered before the gavel fell: "Do you really think I didn't see the fire in your eyes that night?" - He buried people and left chess pieces; Qi Jin survived, not for revenge, but so that he could personally uncover another corpse buried in the rainstorm.
