Where did Nanpai's uncle get so much knowledge about tomb raiding?

First of all, we can say for sure that Nanpai's uncle is very interested in tomb raiding. He must have read many books and movies about grave robbery. At the same time, we should also understand the basic cultural knowledge related to grave robbery, as well as myths and legends and local chronicles. With these cultural kung fu as the foundation, coupled with Nanpai's powerful brain hole and good writing style, he successfully wrote "Notes on Grave Robbery".

Actually, Nanpai Uncle's book doesn't involve a lot of knowledge about tomb raiding, but the background is tomb raiding, the necessary weapons for tomb raiding, the insects in the tomb during tomb raiding, the names of various bodies and coffins, all of which need a certain degree of understanding, which are necessary for doing enough homework. Moreover, before writing this novel, I felt that Nanpai Uncle didn't want to get angry, so many things were thought out by Nanpai Uncle himself.

But in fact, the novels written by Nanpai's three uncles are not entirely original, and they all have certain backgrounds. They are all based on some fairy tales or local legends. Moreover, Nanpai's uncle's brain hole is really not as big as usual. He has buried a lot of holes for his works, but he hasn't filled them yet. I don't think he can fill them all in his life. He has been burying and filling holes, and he has been doing so.

Therefore, it is mainly because Nanpai's three uncles have a certain understanding of this culture out of their love for grave robbery. He also visited some people around him and learned about the story of grave robbery, so in the end, those of us who basically know nothing about grave robbery will think that his grave robbery notes are more professional.
