Two days went by in a flash.
Grey and Void were still hiding inside the cave they made in the volcano. The treasure was already exhausted and Grey was currently giving off the aura of a Ninth stage Overlord Plane Elementalist. His eyes were still shut as he tried to get used to his new cultivation stage, as well as to figure out what the blue light was.
After some time, he managed to locate the blue light. He had tried communicating with it, but he was unable to make it budge in the slightest.
While Grey was busy trying to figure out what the pale blue light was and what it was used for, he noticed a change in the surrounding. The essence around the place was converging at a particular spot.
Void was on the verge of breaking through to the Sage Plane.
