I think the book All-rounded Cultivation Expert is very suitable for you. Although the male protagonist, Xiao Jun, was reborn as an abandoned son of an aristocratic family, he was proficient in everything. He could cure illnesses, refine pills, make talismans, refine weapons, be it the rich young masters of the underworld, or the ancient martial arts hidden sects. He liked the elements of the underworld. He could also see him stepping on the leaders of the underworld and mysterious organizations in the martial arts world. It was very exciting. I hope it can help you. If you like it, don't forget to collect it. Muah ~
