Giving cultivators across the continents more choices.
After establishing the teleportation arrays in the major sect cities across the Nine Provinces, Wang Mu used formations as a prerequisite, delineating the general boundaries of the Nine Provinces, partitioning all regions, known and unknown.
Finally, using the subterranean Spirit Veins of the Nine Provinces as base points, he harnessed the capacity for mechanism artifact refining to forge the Divine Grade State Treasure, the Flying Immortal Tower, establishing a Divine Thought Array spanning the Nine Provinces upon the foundation of nine Flying Immortal Towers.
This grand formation allows for communication and interaction across most ranges covered by the Flying Immortal Towers within the Nine Provinces, through the Divine Light Mirror... no longer limited to regional areas.
In short, it's akin to the internet for the Cultivation World.
