Whoosh!
With a gesture from Gu Chen, the Soul Crystal—radiating an ominous black gleam—instantly flew into his palm.
Compared to the Soul Crystals Gu Chen had seen before, the Ghoul's Soul Crystal was darker and more profound, as if it connected to an abyss within, inciting fear at a glance.
Furthermore, the power within this Soul Crystal was many times more pure than those he had absorbed in the past.
Because this Soul Crystal was a condensed form of the Ghoul's life energy, whereas those Gu Chen acquired in the past were formed from the residual energy of Ghouls after their death.
Hum!
As Gu Chen focused his thoughts, the Soul Crystal hovered above his palm, trembling slightly. An invisible force acted upon it, causing it to gradually disintegrate from the edges and soon vanish into nothingness.
In Gu Chen's perception, a somewhat thick and cold energy coursed up his arm and into his body.
