The hazy figure pinched the spell with both hands, and the black gem slowly fell, fitting perfectly into the gap on the top cover of the soul-refining pot.

A trace of black light emerged from the black gem, merging into the black top cover, and even into the soul-refining pot.

The entire soul-refining pot emitted a crystal-clear light, and the black light on it surged, emitting a cheering and sharp roar, as if celebrating the return of a part that had been lost for many years.

The hazy figure's face also showed a happy expression, once again pinching the spell, and a rich black light emerged from the black gem, forming a strange pattern around it, spinning rapidly.
