Gray fog enveloped the wasteland, and the old civilization died due to spying on higher dimensions. Three hundred years into the Great Filtration Era, humans lived in a barrier city-state where steam and runes intertwined. Zhou You wakes up from a pile of corpses, the centipede scar on the side of his neck is burning, and only the killing instinct remains. In order to protect the girl Shen Wuye who is the "container", he and the down-and-out swordsman Gu Cang set out on the desert road. Blood drives the revolver, lifespan is exchanged for runes, and all power has a price. The church is hunting him down, he is wanted in the past, and the truth is hidden deep in the gray mist. When divinity erodes humanity, he has no choice but to draw his sword. This is a journey of wandering and redemption, asking about the destiny of human nature in a wasteland of despair.
