Kongqing Great World.

Between the world itself and the membrane adjacent to the chaos of the vast void, there are hundreds and thousands of massive floating lands. These lands orbit the world slowly, each densely populated with various cities and palaces, inhabited by countless cultivators.

The existence of these floating lands is intentional by the top-tier hidden cultivators. They serve as the world's early warning outposts, transit bases for entry and exit, logistical supply centers for armies on expeditions, and commercial trade hubs with other great worlds.

Indeed, Kongqing Great World engages in extensive commercial trade, primarily with ancient great worlds of unfathomable strength located deep within the chaos of the vast void. There are also some traveling merchant caravans, mysterious alien cultivators, and even innate chaotic demons.
