Fifth Trophic Level

An unexpected encounter made Zhou Geng, a recent graduate, one of the few humans who survived after seeing an "evman". These strange life forms wander in the blind spots of civilization and feed on humans, but they have never been known to the public. Because there is a group of people who are fighting silently in the dark - GNPO, an organization not well known by the mainstream world. When Zhou Geng was forced to push open the door hidden under the surface of reality, he understood: Some wars never need audiences, only soldiers.
