Lin Heng squinted slightly. Could it be that the person in the mirror couldn't refine the Water Spirit Essence he had imagined?

It made sense. The Water Spirit Essence was in his own hands, being refined by him.

How could a mere consciousness in the mirror refine a virtual object out of thin air?

Lin Heng shifted his thoughts and attempted to have the mirror person operate the "Azure Emperor's Spirit-Devouring Art," while he continued refining the Water Spirit Essence.
