I'm looking for a novel I read a while back. The mc was a mage that was transported in to the game world he played. I believe the first scene was at a carriage in a girl's (also a mage tho low level) pov explaing how magic works and the mc being smug about his knowledge. After that the caravan that they were in was attacked by bandits and the mc has to take action. By the end, the mc gave a magic book to the girl cuz of a mission prompt. His first mission was to go to a magic school to give his lates mentor's research papers to a friend. I think this novel is korean. I can go into the plot further if this info is not enough.
