"The first level contains ordinary books. Most of them are historical documents, books on tools, legendary stories, myths… Of course, there are also some general knowledge magic textbooks, but their level is about the same as your current textbooks. However, there's a gap of more than a thousand years, so they might bring about some new ideas, but they're generally not very useful."
William led Grimm into the library illuminated by the starlight dome.
This was a Baroque-styled building floating in the cosmos. A faint starlight seeped through the gorgeous huge floor-to-ceiling colorful windows, embellishing the complicated and exquisite interior of the building with dreamy colors.
Towering bookshelves extended to the dome. Candle-shaped spirits that flickered with dark-blue flames floated everywhere in midair. They were both the guardians of the library and the main lighting equipment here.
This was the library inside William's Treasure Hall.
