Noah initially did not understand why his foster father, who had finally returned from the underground, would come to him and speak so extensively.
It wasn't until his foster father handed him a piece of storage gear filled to the brim and urged him to study its contents carefully that Noah, the whole Dragon, felt a bit numb.
Because inside the storage gear, the books were sorted and organized by category, but they were not the type of books that could be openly read. Instead, they were books of evil arts, veritable forbidden books.
It is no exaggeration to say that if you took any book out of this ring and walked up to a Paladin, even if they did not strike you with an Evil-breaking Slash, they would surely throw a 'detect evil' at you.
"Too evil! How could he give me such books?"
Noah specifically found a secluded place, took out one of the books, and after flicking through it for a while, couldn't help but click his tongue.
