It seems that when Zhang Wuji first walked out of the canyon, he met Zhu Jiuzhen for the first time. At that time, he told them directly that his name was Zhang Wuji, and his father was present when Zhu Jiuzhen committed suicide in Zhang Cuishan. In fact, he is also a cunning fox. He felt that Zhang Wuji and Zhang Cuishan seemed to be very similar, and both of them happened to be surnamed Zhang. So I made up a story with a portrait, saying that Zhang Cuishan was the benefactor of his family. Actually, I want to test Wuji. As a result, mowgli was obviously excited when he saw his father's portrait, because he had not known him for a long time. These were seen by Zhu Jiuzhen's father. He inferred from this that his initial guess should be correct. After that, he used some risks and honey traps one after another, which led Mowgli to completely release his guard against them before telling the story of the Golden Lion King, but Mowgli believed that they really wanted to find Xie Xun and let him enjoy his old age. It should probably be like this.
