I read a manga where MC get his initial power form a large black sword and a black cat as a (maybe) master from it and after at some adventure he also gets a pet wolf cub. He also strengthens his body by eating the meat of powerful beasts. He gets his cultivation from his family elder
Ah yeah, I've read it but as a manhwa. The title is Zui Wu Dao. But I don't know if it has a novel tho ^^
