When she was twelve years old, she knelt at the front of the execution ground and watched her father's head roll down. Her father said, "Don't cry. If you cry, you will lose." She didn't cry. Nine years later, she disguised herself as a man and assumed the pseudonym Shen Zhiyuan, and was admitted to the Ministry of Criminal Justice with her crime-solving skills - looking at the murderer from the footprints, the time of death from the body spots, and digging for irrefutable evidence of corruption from the account books. She thought she could vindicate her father by looking through the old files, but on the first day she entered the court, she discovered that her father's case files had been transferred in advance, and someone was monitoring her. There was a note stuffed in the crack of the door - "Be careful with the minister." Everyone from the King of Qi, the minister, and the cabinet were waiting for her to make a move. But she's not here to be a pawn. She's here to flip the entire chessboard over.
