While an Apocryphal Antiquity was just born in the Liberated Universe, the Oathkeeper had pierced through the boundary of the Abyssal Universe as his figure looked like a shining white like cutting through the intense aura leaking out of the Universal Constructs.
His descent was actually brought to a halt briefly as when the Blue Slime advanced, its aura had spread out to even be felt within the Abyssal Universe!
This was because the Liberated and Abyssal Universes were the only 2 remaining with the Universal Constructs within them as they were the ones to continue the process of Amalgamation, the barriers between these two Universes already being extremely thin as they could disappear at any moment to allow for complete fusion.
A complete fusion of the Universes and constructs as it would mean an apocalyptic event coming down!
