After the catastrophe caused by the zombie virus, order collapsed. Lu Chen, a doctor of genetics at the Chinese Academy of Sciences, used CRISPR gene editing technology to create a "controllable extremophage" that retains human emotions - a special existence that requires regular injections of "memory stabilizers" to suppress animalistic nature. Holding the key to rebuilding order, he is caught in a more turbulent ethical storm: Should the Extreme Eater be given citizenship rights? In the wasteland, he must mediate between the conservative survivors, swinging allies and the extremophage group, and promote the establishment of a fragile order based on the "Wasteland Bioethics Charter". When his comrades turned into beasts due to drug withdrawal, and trust was on the verge of collapse, Lu Chen risked everything to establish the "Human-Extremophage Symbiosis Research Institute" to seek a slim future for the two groups to coexist on the edge of the blade. This is the ultimate game about the definition of life, emotional value and the boundaries of human nature.
