The Central Library had a total of nine floors, and there was only a limited number of floors that Elias could access.
As a first year student of the academy, he could only go to the first floor, which kept the most basic books. However, as a descendant of a Founding Family, he had access to the fourth floor as well.
The higher one went in the library, the less the number of people that could be found there. Hence, Elias quickly went to the fourth floor and started waiting.
Meanwhile, he also walked across the shelves to check the books. Even though classes ruled this world, there were still many skills that could be learned externally, through hard work and enlightenment by a person.
The books on this floor were more of a guide on how to comprehend the skill mentioned within, but even amongst the most talented ones, it wasn't easy to comprehend the skills.
