The cultivation world was mysterious and limitless. It was a world that was constructed with all the eeriness present in a dream.
Other than the humankind, there were many different kinds of beings living in the world. Violent predators and rare spiritual beings were countless, which is why the old saying said hundreds and thousands of different beings rule the world.
During the last dark era, the humankind was just born. Because they were at the lowest level of the food chain, they were treated as slaves by the other different kinds and were toyed with.
Only after five different dynasties and the various emperors, did the fate of the humankind improve for the humans. They slowly began to gain the capability to fight against the foreign kinds.
After that, many different generations of omnipotent beings fought with their boiling blood. Only then, did the humankind strengthen slowly and became the new ruler of this world.
