Returns to the Immortal Realm
Upon successfully becoming a Ninth Stage Tribulation Immortal, White had a chance of returning back to the Immortal Realm. White then cited a few reasons to stay in the All Heavens and Myriad Realms, mainly of those was Song Shuhang still owes him massive spirit stones.After the birth of Song Shuyu, Transcendence White planned to bring her, Soft Feather, Sixteen and Stone Tablet to the Immortal Realm.
In this timeline, Big Tyrant Song has paid most of his spirit stones debt to White before both of them becoming Ninth Stage Tribulation Immortals. Losing the main reason to stay, White left for the Immortal Realm right after he became a Tribulation Immortal.This in turn caused Song Shuhang to stay in the Ninth Stage Tribulation Immortal and unable to tread the Way of Eternal Life for some time.
