The library didn't differentiate between Aura Knights and Mages. So he could freely access all the books there and learn as much as he wanted to.
If he spent some time understanding magic and aura before trying to grow stronger, then he felt it would be better for him. Unlike traditional mages, he never had a formal education that put him on the right track.
The only problem with that was that he would have to spend a lot of points and time to do that. He had already blown so many points on the pass that he was currently using.
After browsing through a few bookshelves, he started to get a sense of the place and where things were in the place. But he couldn't afford to spend too much time since he wanted to check out the second floor.
He ran out of the first floor and went to the ground floor. He ran to the staircase that led to the second floor. He showed the person his pass and quickly went up the stairs.
