"Ghosts cannot be killed, they can only be replaced." This is the only law I have learned after the revival of supernatural beings around the world. As a salesman in the ghost world, one end of my pole carries supernatural items to suppress evil ghosts, and the other end carries the cost of survival for living people. Trade half your life for the evasive rules of the knocker, trade your memory for the location of the ghost lake, every transaction is pushing the world into the abyss of ghosts. But as long as the cargo can still swing, we have to earn a living for mankind in the supernatural world.
