Hehe, I know a novel that you're looking for. It's called "Fantasy: Becoming Strong by Flipping the Book". With the system, the main character could master thousands of sub-professions, such as alchemy, refining, drawing talismans, and taming beasts. He could master everything as long as he flipped through the books! However, this was not the main character's most powerful aspect. He also had a system that could allow him to dominate the world. Just thinking about it was exciting! I hope you like my recommendation. Muah ~
