《Detective Di RenJie prequel》Ep42:Episode 42
Ling Long volunteered to meet Di RenJie, confessed that Fen Er was killed by her, and had nothing to do with Liang YuXiao. She asked Di RenJie to release Liang YuXiao and go to jail. Di RenJie told her that you want to surrender yourself, of course, but to people easy, I am afraid not you I can say what. Week's law is not like buying and selling, you give me silver goods so easy. Even without such a so-called exchange, it is sooner or later you go to prison. However, Di Gong would still like to know, Ling Long why do this exchange. Ling Long said at least you should believe Liang YuXiao will not kill anyone. Di RenJie said I knew Liang YuXiao was innocent. The murderer of the two murders in the palace was Jin YuanGongZhu, whom Qiao FeiYan hired.
