The mysterious shadow let out a sharp roar, as more Source Black Fog surged from the underground, swiftly merging into the shadow.
It writhed madly, trying to recombine itself.
The Holy Fire Sacrificial Ground emitted an eerie roar, countless strands of Black Fog swept in from all directions, crazily filling the cracks.
The pollution within the field quickly vanished, concentrating on the shadow, trying to wrap around the sword that shone with a star-like brilliance.
Everyone was freed, looking incredulously at the shadow before them, exuding an astonishing corruptive power.
In their minds, the Book of Knowledge exclaimed: "Dear God, Starry Sky City... the entire pollution of Starry Sky City has converged here, it's not just a Black Fog Avatar... it, it is..."
The shadow swelled up, the terrifying darkness was like a fissure leading directly to the Abyss, with twisted roars spewing out, the air emitted a strange hum, as if the whole world was plummeting towards the Abyss.
