"Deep within the Earth lies a truth humanity dares not reveal." In the wasteland era, humanity, over two centuries, divided itself into two groups: gods of the upper city and slaves of the lower city. Chen Bei is the third. He awakens in a cryogenic chamber two hundred years ago, finding himself a "Resurrected"—a coveted prize for all factions. The Human Council needs their original genes, the Android Alliance needs them to guard the secrets of the Earth's core, and the forbidden creatures are equally eyeing them covetously. Originally intending to simply drift along, Chen Bei is forced into the fray by the disappearance of a high school girl. When humans, androids, forbidden creatures, and Resurrected vie for power... four forces, one truth. What lies hidden beneath the Earth's core? ...Until he sees blue blood flowing beneath the android's skin. Until he hears the distress signal from the spaceship. He finally understands—humanity's catastrophe has never been a single event. ...Until that day, as Chen Bei stands with his hands behind his back, smiling and serving his guests, they realize that the creatures of this blue planet have never been mere prey. "Welcome to the Happy Sheriff's Office." [All based on real-world scenarios, including melting polar ice caps, ancient viruses, prehistoric giants, and human genes.]
