"Boom—!!"
The rolling metal door was blasted straight off its hinges by a tremendous force, crashing to the ground in a twisted heap. Dean charged in first, the ordinary hunting knife in his hand now wreathed in an almost imperceptible warm current of air.
Though it still looked utterly unremarkable, it contained the power to touch the soul and kill ordinary demons.
Sam followed close behind, his pump-action shotgun aimed at the altar, his gaze sharp.
Wu Heng appeared soundlessly amid the smoke and dust at the doorway, the hem of his black trench coat fluttering faintly. His gaze swept over the bloody hell within the factory before finally settling on the three White-Eyed Demons and the priest's corpse, which was fluctuating abnormally at the center of the ritual array.
"Good evening, you disgusting bastards."
Dean roared, his voice hoarse with fury. "Your midnight slaughter party is over!"
The sacrifice continued without pause.
The cultists carrying out the execution turned a deaf ear to the trio's arrival.
The blood-red light upon the altar flickered violently, wavering between brightness and darkness.
The priest, who had bitten the test tube apart, had his throat slit, and was being shoved toward the energy black hole by the young demon, began convulsing even more violently. The residue inside the shattered test tube, containing stripped angelic will and the power of rules, reacted with his dying soul.
The priest's devotion was ignited and turned into fuel, causing the contents of the test tube to rapidly merge with the priest himself.
A deep cavern appeared at the center of the altar, like hell's fanged maw opening wide.
The chilling wails of countless ghosts and the stench of sulfur surged endlessly from within like tangible streams of black air, assailing the nerves of every living being present.
