When the "blight" virus wiped out civilization, special soldier Cheng Mo survived alone in the ruins. During a material search, he accidentally intercepted an encrypted distress signal and followed the traces to rescue Lin Xuan, a female doctor who had key data on the vaccine. However, he was involved in a hunt by the military and the mysterious organization "Genesis". During the escape, Cheng Mo was in a desperate situation and embedded the "Prometheus Key" USB flash drive containing the hope of mankind into the wound on his back, sealing the fire with his flesh and blood.
In order to protect the comatose girl Niu Niu and her dying companions, Cheng Mo was forced to swallow the radiation monster "Lord of Decay" born on the sea platform. His body underwent horrific mutations of metal and flesh, and he gained the ability to temporarily control virus creations, but he was also on the verge of losing control. When he was seriously injured and on the verge of death, the real Lin Xuan came to the rescue at the cost of a broken arm. Everyone escaped in a lifeboat and drifted into the dangerous Sea of Rust.
The mutated key that had been dormant in Cheng Mo's body reawakened due to the leakage of corrosive mutated liquid. An armed fishing boat painted with an unknown skull logo approached through the thick fog. Inside the boat were companions in urgent need of treatment, Niuniu in a vegetative state, and a body that hides the future of mankind and is sliding into the inhuman abyss. The thorny road of hunting the doomsday extends again on the new coast of ruins.
