I recommend Grave Robbing: Starting from Listening to Thunder. Although it is not very relevant to the specific problem, as part of the Grave Robbing Chronicles series, it also includes the part where Wu Xie disguised as the third uncle. In this novel, Wu Xie and the Iron Triangle began their tomb raiding adventure, which included Wu Xie disguised as his third uncle and killing the three uncles who betrayed him. If you want to know the specific chapters, I suggest you read this novel yourself. I hope you like this fairy's recommendation. Muah ~😗
