Jun Wu Jiu thought about it, so he decided to go back to Hecheng without waiting for Cheng Yang. In Hecheng, he sees things and thinks about people, and finds Nishang to tell the mystery of the previous Lefang case, but the truth can no longer be verified. Then they went to the suburbs again to look for the little fox girl, but found that the little fox girl had disappeared. They hurriedly searched for it, but could not find it. Cheng Yang and the three returned to Hecheng, hurriedly retrieved Jun Wu Jiu, and provided them with information about Si Wen, Jun Wu Jiu, based on some handwriting clues, found out that Fan Wen who had been beside them was actually Si Wen, so he hurriedly hunted down , and finally caught Fan Wen who kidnapped the woman. After interrogation, it was found that Fan Wen hated Du Xiaomei and tortured her to death. However, when Fan Wen thought that he was satisfied with everything and had no regrets, Jun Wu Jiu asked Du Siwen's aunt to confront Fan Wen. Only then did Fan Wen know that Du Siwen was actually his biological son. The misfortune eventually led to a tragedy in the world.
