During the Xianfeng period of the Qing Dynasty, Ning Guta, the convicts Su Shuhe and Liu Laosi dug up a priceless ginseng doll and decided to auction it.Xu Guandai, the general stationed in Ninggu Pagoda, ordered Gu Pingyuan, a prisoner who had read books, to take charge of the matter.On the day of the auction, the ginseng disappeared.Amid everyone's doubts, Su Shuhe committed suicide in anger to express his innocence.Xu Guandai ordered Gu Pingyuan to investigate the matter.

Gu Pingyuan analyzed from various clues that the housekeeper of Li Qin, a Beijing businessman who participated in the ginseng auction, reached a private deal with Liu Laosi and took the ginseng in advance.The truth came to light, Gu Pingyuan found Liu Laosi, but unexpectedly, Liu Laosi and Su Shuhe's son Xiaohu stabbed Liu Laosi to death. The Su family's sister-in-law also seized Liu Laosi's body.As a result, the two villages where the two parties were located clashed and agreed to fight together on the glacier.
Gu Pingyuan was ordered by Guandai Xu to take the token to resolve the matter.At this time, Shanxi businessman Chang Si and his daughter Chang Yu'er were about to enter the gate of Ninggu Pagoda. Gu Pingyuan and Chang Yu'er looked at each other with lightning and were very curious about each other.Gu Pingyuan came forward to mediate the conflict, and the Su family's sister-in-law proposed that as long as Gu Pingyuan promised to send her son Xiaohu out of Ning Guta, she would promise to return Liu Laosi's body.Gu Pingyuan reluctantly agreed, and the conflict stopped.Although he solved the matter arranged by Xu Guandai, Xu Guandai was wary of Gu Pingyuan's position in Ning Guta, saying that he could kill Gu Pingyuan at any time.
