From the description of the Quintessential Primogenitor Enneagonal Existential Jewel, it was expressed that Entities had to attain the Fourth Vitalis or Vacuous Awakening before they could even try expanding said concepts towards Extremity.
Noah didn't have to wait for this as even while he was undergoing his Third Awakenings at this very moment, the Fourth ones were far away.
The Enneagonal Existential Jewel stepped in to solve this issue as he could innately feel that within a matter of days, the accumulation of Existential Authority would reach the required level and grant him the right to expand these concepts!
This in itself was a terrifying capability.
Even more terrifying was that in mere days, he had truly progressed from the First Existential Awakenings and he was already on his Third.
Other Entities took thousands or millions of years.
