This is a human world where monsters and filth are prevalent. Various monsters that maintain animal characteristics bear the balance of the world. The filth is rotten and smelly, and relies on killing people to gain lifespan. Monsters generally rely on killing filth to gain lifespan. There are two types of filth. One kind enjoys the pleasure of killing. If this type is killed on the spot, the monster gains lifespan. Those who have been transformed from human beings into filth and are not used to killing people will be arrested and managed by the Central Bureau.
Those who are hunted are not necessarily rotten filth, but also monsters that willingly degenerate to harm others. Monsters that willingly degenerate generally do not mainly kill people, but mainly abuse them.
They like to see the fragility and vulnerability of human beings hanging on cliffs or drowning in rivers when they are on the verge of death. Therefore, in addition to killing filth, arresting these degenerate monsters who take pleasure in abusing humans is also one of the tasks of the Central Bureau.
Monsters gain lifespan by killing filthy and corrupted monsters. The lifespan gained can be distributed to their families through certain methods, but 30% of their lifespan will be lost each time they are shared. Therefore, the monsters in the system work hard for their lifespan and take responsibility for the stability of the world.
