The cultivation technique for his Ice cultivation, Primordial Frost Scripture, was simpler.
And its main aim was simple: to absorb Frost Energy. It was perfectly in sync with the Apex Cultivation stages.
But this Void Asura Grimoire was unlike anything else he had ever seen.
Even right now, as Ryuk finished reading it for the third time in a row, he still didn't even know how this was supposed to rhyme with the cultivation stages.
Just what node will he achieve to reach the Ascension stage, or the Dominion stage, or the Cataclysm Stage? Ryuk had zero idea still.
But then, he knew well that even though he couldn't comprehend this fully, the Void Aura was a technique that was beyond even the Primordial Frost Scripture.
For one, it doesn't just let him absorb Void Energy and call it a day.
It actively mutates him into something else. A new race.
That was like the ultimate peak of his Primordial Frost Scripture that rewarded him with the Frozen Physique.
