Pollution Outbreak

Sharp and deafening sirens wailed in the air, shattering the tranquil silence of the night. It was the emergency signal issued by the advanced technology in the Special Department, designed to detect the source of abnormal dark energy within a certain radius and thus allowing the exorcists to nip the evil in the bud within the shortest time possible. The alarm's frequency varied depending on the urgency of the situation, and right now… it clearly meant disaster!

The guard on duty, who had been dozing off, abruptly jolted awake with bleary eyes. "W–What…?" 

At first, he had no idea what he was seeing, just that the walls around him were shrouded in a pulsating crimson glow. In the next moment, however, his eyes focused on the panoramic screens displaying the map of the entire city, and his jaws dropped, eyes widening to the maximum. 

"Oh God…" he breathed out, horror etched across his features.
