The Great Library was located in the center of the Royal Academy. The entire library was a spiral-shaped tower that pierced through the clouds. There were no windows on top of it, and the only thing that was exposed was a large door at the bottom. The large door was filled with an intense magical aura. It was as if thousands of different types of enchantments had been constructed using different types of magic. Even diamond-tier experts would not be able to destroy it in a short period.
Furthermore, once it was forcefully destroyed, the books in the library would be automatically destroyed.
Standing in front of the library, Watson sighed at the grandeur of the library. He took out the golden key from his neck and inserted it into the door in front of him. With the sound of a machine expanding, the many magical enchantments in front of Watson slowly squirmed and formed a translucent door in the air.
