Chongxuan Academy possessed nine tall towers, each a Teleportation Array established by a Tribulation Realm Great Power. The academy's many School Principals had then worked together to build a Treasure Pagoda around each one, integrating it with the array to allow for instantaneous travel deep into the Outer Void.
Over many years of development, the academy had invested countless resources into these nine towers. Today, the combined value of the towers, the Outer Floating Lands, and their arrays was truly immeasurable.
The nine towers each corresponded to a different region of the Outer Void. The one Du Ruo stood guard over was exceptionally distant from Qianyu Heaven, even farther than the space between two World Heavens.
