Apocalyptic Middleman

When he opened his eyes, Song Yushi found that he was still in the rented house. He didn't know the year and year, but he saw the dim yellow world outside through the balcony glass. After listening carefully, I found that there seemed to be a strange noise outside the door... He was originally just a stand-in for a martial arts actor who was almost unemployed, and he worked part-time as a food delivery person in order to survive. Why did he wake up in the apocalypse where the undead were everywhere, but the undead seemed to have no ill intentions towards him? Rampant in the apocalypse full of conspiracies and choices, he vaguely felt that he was different from before, and seemed to have skills that others did not have. Finally he discovered that he was the middleman in the end of the world... This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
