Ma Dayou decided to go with Jiang Qian'er to find a way to change his body. During the search, they happened to meet Yang Hongsu who came to find the princess to settle accounts. Yang Hongsu thought it was the princess who caused Ma Dayou to become an eunuch. Seeing Yang Hongsu's misunderstanding, Ma Dayou andJiang Qian'er explained to her that Ma Dayou was not a eunuch, and asked her for help in investigating official corruption. In order to change her body, Ma Dayou invited a goddess and a monk in the palace to try various methods.All these practices and chanting sutras failed. Old General Yang accidentally saw this scene and thought that the princess's behavior was inappropriate, so he went to discuss the princess's behavior with the emperor and queen.After many attempts by Ma Dayou and Jiang Qian'er failed, they found a Taoist priest. Following the Taoist priest's words, they came to the ruined temple where the souls had been exchanged. Unexpectedly, the Taoist priest was actually a charlatan.
