Gone
Everyone kept themselves far away from Tixan and Lani so they wouldn't get involved in the Tribulation. Of course, Lani and Tixan stayed far away from each other as well to not make things difficult. As long as they ascended from the same place, that would be fine for them.
The two then concentrated on their cultivations and finally made the last push. With that, their cultivation had reached the highest point it could possibly reach in the Mortal Realm, which naturally called forth the tribulation clouds. As everyone knew, Luvile Universe's Tribulation was Purple Lightning. However, it mattered not for the ascension tribulation. After all, this specific Tribulation would call forth all elements instead of a single one.
Back then, Krune had a difficult time passing through it. It was only thanks to Luvile that he succeeded in the end. However, that was also his last breakthrough in the Mortal Realm. The next ones happened in the Godly Path Realm.
