It could be said that Krune was pretty much the fastest to ever become a God. After all, on average, it took a decade to break through every stage in the Semi-God Realm, a century per stage in the God Trial Realm, a millennium per stage in the Elementary God Realm, and ten thousand years per stage in the Primal God Realm.
After this, one would begin preparations for their final breakthrough, which would take tens of thousands of years. Even on average, a cultivator needed at least two hundred thousand years before they became a God.
On the other hand, Krune took only twenty-eight thousand years to do so. Honestly, no matter how talented he may be, this was an impossible feat.
Nevertheless, it was only made possible thanks to the Tilk Realm's breakdown. Because of that, his cultivation grew at a staggering pace, allowing him to attain this status in record time.
Krune and Sterlena both reached the God Realm in cultivation.
