A sharp light appeared in Cain's eyes as he felt the unique construct born out of the Essence Star and his soul consuming every dot of Essence Wave he had. That was a critical process, and usually, cultivators would ensure they had all sorts of wave crystals at hand, but he had something even better.
"AHHHH!" Cain roared as he triggered the full power of his Primordial Path, drawing the world's natural energy and cosmic force with as much power as he could, fusing it into the Essence Wave that the construct was devouring.
Natural energy and cosmic force were forces of an even higher tier than normal Essence Wave one could find in supreme wave crystal, and there was practically a never-ending supply of it, so Cain could give the construct as much as it could take.
Oceans of energy flowed through Cain's body into the construct, which took everything with a ravenous force until finally, after five hours, it could no longer hold anything more.
