Primeval Ent

A Normal Ascension is a process of a cultivator who has reached the limit of that world and is unable to progress any longer in that world and needs some external push like an invitation from an Emperor from the other worlds.

After going through the Lightning Tribulation for the Normal Ascension, that particular cultivator would become a native of the higher world.

Once he becomes a native of the higher world, his cultivation talent, potential and even his body physique would be upgraded to the level of an average cultivator's talent, potential and physique of that higher world.

Skaros, the Primeval Ent was the last surviving one among his race and the oldest living being in the Purple Stone World.

His cultivation has been stuck at the peak King Realm and with the current resources in the Purple Stone World, he couldn't break through to the next level much less ascending to the Heavenly Realm.
