During the Jiading period, the soul of a modern forensic doctor entered the Ninth Grade Prosecution Judge. He held a "cleansing of grievances" and a silver needle, examined autopsies to identify grievances, and subverted the court with poisoned firearms. The cold-faced female painter of Jiaxing Prefecture used pens to depict bones and other people's hearts. The corpse's voice serves as evidence, and the court serves as matchmaker. Every time a case is solved, the legal embrace is one step closer. With the undercurrent of intrigue, they save the world first, and then each other.
