Knowledge Is Power

Naofumi finds himself teleported to another world after reading a book in a library, but before be transported he was able to read almost the entire book from front to back, and due to his photographic memory this was quite the easy task, the book was massive and had a whole bunch of lore on monsters and there weaknesses, how to level up, secret dungeon, rare items and artifacts, it also stated alot about magic manipulation in the book, but he most interesting was a view at the four cardinal heros, and how the shield hero was manipulated by the princess and and was blamed for rape. Will history repeats itself will naofumi get tricked again well you'll just have to find out. (The start of this where he knows he's going to get tricked was thefted from a book I read but I can't find it for the life if me)
