In the Mortal Domain, if a cultivator's cultivation reached the Mahayana Realm, they could ascend to the Immortal World, where those with some talent could achieve the Heavenly Immortal Realm, and some could even reach the Profound Immortal Realm.
However, most Ascension Stage experts from the Mortal Domain, upon ascending to the Immortal World, at best reached the Profound Immortal Realm. Rarely did anyone achieve the True Immortal Realm.
The cultivators of the Mortal Domain all strive to reach the Ascension Stage before ascending because after the Profound Immortal stage, each realm is divided into three levels.
From this, it can be seen that the higher the cultivation, the more advantageous it would be for future cultivation after ascension.
Tian Lang, Yi Mu, and Qingyue, although their cultivation had reached the Ascension Stage and they had ascended to the Immortal World, ended up on Qiming Star, where Immortal Essence was scarce.
