I Should Have Eaten Food from the Underworld

On the night when he failed the postgraduate entrance examination, Lin Yan accidentally entered an abandoned training building, and his name was suddenly called on the radio in the building. "Candidate Lin Yan, please enter the seventh examination room." He thought it was just a prank, until he saw rows of "people" with their heads down writing papers in an empty classroom, and saw in the mirror the seventh examination room that shouldn't exist. After escaping from the abandoned building, two small blood-red words appeared on the back of his hand: Miss an exam. When he took the make-up exam seven days later, the ghost had followed him back to reality. Since then, names have been called out in the middle of the night, paper figures have been added, reservoir stand-ins have been used, old houses borrowed for longevity, and mountain villages have begged for seals... Folk horror stories have come one after another. Only then did Lin Yan realize that he was not simply a ghost, but had a flaw in his fate. He should have eaten the food of the underworld and should not have taken the road of the earth. In order to survive, he could only learn folk Taoism while figuring out the rules of the underworld. But the closer he got to the truth, the more he discovered that someone had stolen his account from the underworld, and now, the account began to be recovered one by one.
