Chapter 648: 25,000 Kilometers on Fiend Mountain

The reason why Meng Chuan's outer realm true body didn't cultivate on Fiend Mountain's path of the mind was that he didn't want to affect his homeworld's true body, which was studying the Void Catalog.

On the path of the mind, the mountaintop's voice constantly attacked his Essence Soul. The interference was too great. Meng Chuan undoubtedly gave the comprehension of the Void Catalog top priority.

The Void Catalog is the most precious manual I've obtained to date. Meng Chuan was enamored by it. Although he had memorized all three volumes with a single glance at his cultivation realm, he had taken a long time studying every word and every painting. He even went to a Chaos Hole's depths, Earth Cloud Mystic Realm, and the Great Seal Eternal treasure to verify his ideas.
