"The Ghost Pill!"
Just like a Demon's Core from a demon, this ghost pill was an item whose life was interlinked with a fierce ghost, considered their most prized possession.
This ghost pill was extremely restrained, lying quietly there without any spirit light showing.
Yet, when Bai Ziyue saw it, a slight smile of joy involuntarily appeared on his face.
With a quick movement of the Soul-Gathering Banner in his hand, a surge of Yin Qi instantly emerged, sweeping it to his front.
Without any hesitation, the spiritual power inside Bai Ziyue's body quickly poured in, and the Soul-Gathering Banner shone brightly, emitting strands of blue-black light that penetrated into the ghost pill.
Soon, strands and wisps of intense black Yin Fiend Qi were drawn out from the ghost pill and converged into the Soul-Gathering Banner.
