Demons and evil spirits plague the world, Heaven and Earth show favoritism, human hearts are deceitful, and ghosts and monsters spread calamity! When Chen Nian crosses into this world, the first thing he sees is more than eight hundred villagers devouring one another at his own wedding banquet. To survive, he destroys his own appearance and chants the Tianpeng Incantation, disguising it as a command from the underworld. Fortunately, the Patriarch takes pity on him, bestowing the Northern Emperor's talismans and teaching him the Great Mystery Black Register, allowing him to become an agent of the North Pole. Now the Daoist descends the mountain: he will not save the wicked, only kill them! He slays demons and devours evil, vowing to eradicate every wicked spirit under Heaven!
