The search for a solution was actually harder than Rui expected. The Floating Sect's library wasn't bad, not at all. Because they were so isolated from human civilization, they had grown to become developed in all fields beyond what a normal sect would.
This included having a decently flourished library with information on various topics. If they ever happened to be in need of information and needed to scour through the literature of any field, they could do so with better ease.

However, the library had a greater breadth as opposed to depth.
It contained literature from many fields but did not go too deep in each field.
