Xuan Nu followed Zhou Bai's footsteps without glancing sideways as they walked through the library. Zhou Bai's Primordial Spirit energy scanned the bookshelves, and the titles of the books surfaced in his consciousness.
The book that Dr. Zhuang mentioned is called "Miscellaneous Discussions of the Four Seas," and it requires a seventh-level clearance.
Although Zhou Bai had nominally defected from Donghua City and didn't possess such high clearance, he had just sent Xuan Nu to find the Grand Elder and managed to obtain a temporarily issued seventh-level clearance to access the books here.
The books that can be borrowed with seventh-level clearance aren't numerous. After all, besides the Daoist canons of the seventh realm, only a few profound Daoist techniques, martial arts, all historical records, and various miscellaneous confidential information meet this secrecy standard.
