The so-called Ascendance Heavenly Tribulation is like the entrance exam of the Immortal Gate. If you can emerge from the countless cultivators in the Lower Realm and cultivate to the Realm of Void Refining, you are recognized as a talent by the Immortal Realm, able to rely on your efforts to become a new member of the Immortal Realm and be accepted by the other superpowers.
For example, the Nine Heavens Demon Vibration Ancestor gained the opportunity to listen to the Dao at the Jellyfish Palace after Void Refining Ascension, and during the third listening, he comprehended his own Great Tao, successfully harmonizing with it, which led the Mother of Water to descend and take him as a direct disciple.
However, with several great changes in the Tianhe Realm, the backdoors created by several Great Divine Power Wielders for their descendants' ascendance were either sealed, the keys lost, or destroyed.
