Noah's dantian shrunk after the energy released by Heaven filled its insides. His darkness boiled and released nutrients that his organ absorbed to elevate its level.
The darkness also changed. It had the form of a series of sword-shaped crystals that emitted a dark light before, but it turned into a pitch-black gas after the breakthrough.
The gas appeared made of a sharp substance that didn't radiate any light. The power that it contained was immense, and a sense of completeness filled Noah once that energy began to interact with the other centers of power.
Meanwhile, part of the energy released by Heaven flew high in the sky and opened a large crack. White light filled the insides of that fissure, and a captivating aura came out of it as it spread through the world.
The path for the Immortal Lands was open. Noah only had to cross the crack to reach the higher plane and leave his world.
