The so-called Dustless Lower Sphere was one of the various realms.
Despite being a lower sphere, its expanse was vast.
The lower sphere was divided into many different realms based on size, resources, and other factors.
Jiang Chengxuan knew that besides their own Dustless Lower Sphere, there were others like the Broadened Mortal Sphere and the Four Extremes Lower Sphere.
Each of these divided lower spheres contained many worlds.
Among them,
Their Nine Essences Cultivation World and the Astral Origin Cultivation World mentioned by Huang Ling'er were part of the Dustless Lower Sphere.
However, for reasons unknown, as per Huang Ling'er's information from her father, all worlds within the Dustless Lower Sphere had lost their ascension passages.
This news was undoubtedly a calamity for all cultivators in the Dustless Lower Sphere.
"Ling'er, have you told anyone else about this?"
