The Last Temporary Worker in the Underworld in the Human World

My name is Shen Yuan, a living person and the only temporary worker of the Underworld Corporation in the human world. Three hundred years ago, the underworld was restructured, and all business in the underworld was outsourced. Dead people can't do this job in the human world, and living people won't do it. My job is not complicated: I receive complaints from ghosts, record their last words, and occasionally come to deal with things that linger in the human world. The salary is not high and the risk is not small. The most troublesome thing is that none of the temporary workers have been made permanent alive. Some died in the field, and some were lost after processing the last work order, leaving only a few unclaimed resumes in the archives. Three months after I joined the company, I received my first full-time job evaluation. Dealing with an abnormal space that has circulated in the human world for seventy years. Everyone who enters it has received a ghost call. The call comes through and they're dragged into the place. Only my phone didn't go off. In the receiver, the ghost was silent for a long time. "There's no one in the underworld anymore. Why did they send a temporary worker?" "There is no one left." I looked at the blood gradually rising under my feet, "I am the only one left in this world." "Then what are you going to do?" I opened the work order and checked the assessment requirements. "Survive first, handle complaints, and close work orders." "Then what?" "Regularization." I paused. "Then resign."
