At the birth of his new body...it was actually already at the Universal Realm!
The first time that Noah split his soul, he had to elevate the Realm of Alexander all the way to his main body's current one, such a thing being easy as the body just used the essence of the main Realm to quickly rise, and this only worked because it was in the lower Realms of power.
But the second time that Noah split his soul, the race of his new body was at the Universal Realm at birth as this being itself...was a Universe! But the more stupendous thing was that this body didn't have an Origin.
The body itself was an Origin as when Noah advanced it in power...the possibilities were just fantastical to think about!
The beating heart of his main body calmed as the physiology of his Universal Body was too unique, even its heart being filled and made up with billions of Galaxies as just its heartbeats came in low Ancient thumps.
