Only when he reached the Ninth Floor did he finally perceive an obstruction.
It was a Divine Soul Restriction of Refining Void Level!
Luo Chen understood at once: the Nine Layers of the Book Collection Pavilion of the Su Ling Sect should have been established according to cultivation realms.
The Sixth Floor and below correspond to the Golden Core Realm and realms beneath it.
The Seventh and Eighth Floors are places that only a Nascent Soul True Master may set foot in.
As for the Ninth Floor, it must have been personally set up by the Taisu Spirit Monarch, and only a Divine Transformation Great Power may enter.
However, for Luo Chen, this was already enough.
A Nascent Soul True Master, whether in the Mountain Sea Realm or in the Mystic Realm, is a force that cannot be ignored.
The information and knowledge such a person can come into contact with are sufficient to be counted as secret matters of the Immortal Cultivation World.
