I recommend "This Man Cultivates by Grave Robbing". The main character of the story, Su Qingsheng, is a young man from a family of grave robbers. Once, he was coerced into a fight and transmigrated to the Immortal Cultivation World, where he was involved in the battle between various major forces. He relied on his ancestral gold-digging skills to start a tomb raiding journey in the cultivation world. He met a cave of an immortal cultivation sect and began his cultivation journey. I hope you like this fairy's recommendation. Muah ~😗
