The fourth stage of the Omniverse level was already the limit a living being could reach.
An existence at this level only needed to stand there to directly exert deep interference over the entire Omniverse, turning the whole Omniverse into a toy in its hands.
Everything would be instantly enslaved by an Omni-Four, with no possibility of fighting back.
Omni-Four was the pinnacle life could attain.
As for anything higher, it was either the Ultimate level—beings like OAA and God, who had already surpassed the limitations of "life," the final end of all things and their original source—or the fifth stage of the Omniverse level that existed only in Donnie's projections. That was a level capable of matching Ultimate beings in combat power.
The difference was that even if an Omni-Five could fight an Ultimate being to a standstill, Ultimate beings existed eternally and could never meet an end called "death," because death itself was merely an insignificant component of an Ultimate being.
But an Omni-Five was ultimately still within the category of life. It could be killed, weakened by severe injuries, and would still die if weakened too much.
That was the difference.
Donnie had long since given up on the possibility of becoming Ultimate. If he wanted to ascend to true supremacy, he could only take the path of Omni-Five—unless he was willing to become the avatar of some Ultimate powerhouse.
Moreover, Omni-Five was theoretically impossible. Omni-Four was already the limit.
Donnie continuously clashed fiercely with the Dark Goddess while cautiously studying the battered Omniverse.
Every time he drew upon immense power to contend with the Dark Goddess, Donnie felt a sense of dread and unease.
