The monthly income of a professional Corpse Fighter was over ten thousand, so where did these corpses come from?
My answer may not be in line with your question. The phenomenon of the professional " corpse salvager " often appeared in novels, but it did not exist in real life. From the perspective of the novel, corpse salvagers were usually some extreme organizations or criminal groups who used illegal means to obtain corpses from zombies or other deaths. These organizations might kidnap, rob, or murder humans to obtain corpses. This was illegal and very dangerous. In reality, the people who retrieved the corpses were usually professional staff sent by the local public health agencies, the police, or other government departments. They collect and dispose of zombies or other dead bodies through legal procedures to ensure public health and safety. Although novels often described the high income of corpse fishermen, this situation did not exist in real life. These plots are usually fictional to attract the reader's attention.
