The reason Su Yang thought this way was because the World Tree was born from Chaos.
However, how the World Tree came into being, no one knows.
The only thing people know is that the World Tree was born within Chaos. After that, fruit began to grow on the World Tree, and those fruits became the Great Worlds.
Within these Great Worlds, life was born, cultivation began, and various activities started to appear. Finally, the prosperous Three Thousand Great Worlds came into being.
But who can be certain that before their Three Thousand Great Worlds, there weren't other Three Thousand Great Worlds, or even Four Thousand Great Worlds, or Five Thousand Great Worlds?
If all these Heaven-Reaching Giant Trees represented one World Tree, then perhaps countless Great Worlds and countless lives existed before this!
