"Hmmm…" Grehha stared into the depths of the darkness as his figure—enveloped by an Empyrean Incubator—continued to sink.
His Tertiary Nature of Empyrean Incubator was very versatile in nature. He could store any organic substance in it and ensure it doesn't get damaged, rot, or oxidised. Whether it be food or a Pranic Beast egg, his Empyrean Incubator can preserve them all.
Moreover, he could also use it as a shield, relying on this protective bubble to defend himself. Not only was it capable of blocking all traces, but with some tweaking and some layering of Empyrean Incubators that reflect light at an overall angle of 360 degrees, he could even make it optically invisible.
He was currently using that to safely descend through the waters of the Red-Draft River. The density necessary to sink deep and the robustness to withstand the increasing water pressure was provided by his Secondary Nature of Internal Inertial Gravity.
