Void Returning is the 6th level of cultivation. The title given to cultivators who have reached this stage are "Saint" or "Old Sage". Those who cultivate to this realm have great magical powers that can transform a planetary world.
All of the 12 Gods of the Light Race are all in the Void Returning realm and the existence of the rebirth period.
In the Tiannan Star Province those who have reached this realm are the leaders of core sects, clans, or races. However, in the Central Galaxy World this level is far less revered as it is common to see Void Returning cultivators as only Elders or high ranking sect members.
The Immortal Feather, a treasure that was used as a plaything by ancient immortals, has an existence comparable to this stage and the only way to track it is to reach the corresponding realm.
Void Returning Saints are able to look across billions of galaxies.
