Detective D. Renjie
The story goes like this: Lin Yongzhong is the real Xue Qinglin, and Xue Qinglin and his brothers should have been water bandits. They killed Lin Yongzhong's whole family, only escaped from the infant Lin Yongzhong and Jin Niang, as well as buddhist nun Yi Chang of Lin Yongzhong.
In order to get revenge, Lin Yongzhong came to Wuping County as a county magistrate and sent Zhang Yi and Jin Niang to Houfu as undercover, which led to a series of things.
After Jin Niang stole the letter, she hurried home overnight, but because Hou Fu's slaves chased her home, Jin Niang had to give the letter to Si Wu and Si Wu hid it in her shoes. Later, Jin Niang went to the mortuary at night to look for the old man Si Wu, but found no letter. However, after Jin Niang visited the morgue at night, Lin Yongzhong immediately understood what had happened, so he drove out of the morgue and found the letter on Si Wu.
Finally, De Renjie made Feng Wanchun a monk, and Lin Yongzhong replaced Feng Wanchun with Jiangzhou's long history. Jin Niang finally returned to normal.
