Before the immemorial age, people usually thought that the world was only as big as what they saw.
After Lu Huan created the path of immortal cultivation, this world began to turn from a Savage Land to a civilized one. It gradually developed into a Grand and advanced primordial immortal cultivation civilization.
After the World became a world of cultivators, people's understanding of the world also began to gradually change.
People began to realize that the world was diverse. Other than the main world, there were all sorts of small worlds, and even some secret realms that could not even be considered a world.
But all in all, whether it was a small world or a secret realm, they were both dependent on the origin world and could even be considered a part of the origin world, only they were relatively special.
