The Scripture Library, Treasure Pavilion, Devil-suppressing Division, and so on were the core departments of the Kingdom of Dawn and could exchange for various resources.
However, some restrictions on some key and core resources were imposed on these departments. For example, if one wanted to exchange the treasures in the Treasure Pavilion, one could just exchange them with points for low-level, medium-level, and high-level treasures. Whereas the top-rank treasures could only be exchanged with points and merit points. The best top-rank treasures could only be exchanged with merit points.
It was the same for the other two departments. Many of the top rank books in the Scripture Library could not be read just because you had points. The top knowledge required qualifications. One had to either have enough merits or get special approval from the Lord of Dawn. otherwise, no one could read it.
