Gravis had initially planned to find another opportunity to temper himself. After all, that was the very reason why he had only become a level one Ancestral God.
However, everything had turned out differently from what he had planned… as always.
Gravis' Will-Aura had reached the level of a level four Divine God during Samsara. Gravis had been under an intense feeling of doom and danger for the ten million years of Samsara, which had done wonders for his Will-Aura.
This put Gravis in a very awkward position regarding tempering.
With his strengthened True Law of Suppression, no Ancestral God could possibly resist Gravis' illusions, making him unkillable in the Realm.
Yet, Gravis also couldn't kill level nine Ancestral Gods since he simply couldn't muster enough power to injure them, even if they simply stood there without doing anything at all.
