In 2073, fog engulfs the city and gods descend. Daxia's Night Watchers, mortal in body, raise their blades against the abyss, their blood staining the heavens.
Su Yan, a partially blind painter from Cangnan, has the power to see through the fog in his left eye. He can perceive the flow of energy, see the true forms of demons, and discern the ailments of gods. This is the only memento left him through forbidden arts by his Night Watcher father, who vanished three years ago, and the only key to the path of slaying gods.
A Night Watcher token leads him onto a bloodstained battlefield, where he fights alongside powerful members of the Nightfall team, including Lin Qiye and An Qingyu. Together they face the fangs of the Mist Stalkers, uncover the truth behind the defilement of the Fog God, and expose the Ancient God Church's chaotic conspiracy.
From the fog of Cangnan to the Antarctic ice fields, from Ward Seven of the Gods' Psychiatric Hospital to the heart of the seal binding the Lord of Chaos, he breaks the Fog God's contract with an oath of light, heals the gods' ailments with his fog-seeing gift, and wields the power of two gods in a mortal body.
When the fog finally clears and the ancient gods bow their heads, Su Yan at last understands: slaying gods was never about wiping them all out. It means standing before countless people with the will to protect, letting the light shine through the darkest night, and enabling the path of mortals to rival the heights of the gods!
Within Daxia, gods may not tread. Through the fog, the mortal path is not walked alone.
