I Stumbled into the Underworld Group and Sold Latiao to the King of Hell

Chen Sheng, an utterly ordinary office drone, is pulled into a bizarre chat group in the middle of the night called the "Underworld Internal chat group." Its members turn out to be Black and White Impermanence, Ox-Head and Horse-Face, and the Ten Kings of Hell! When he sees the King of Hell complaining, "The food down here hasn't changed in a billion years. It's bland and tasteless," Chen Sheng cautiously sends a red packet containing instant noodles. [Ding! Black Impermanence claimed your "Braised Beef Noodles" and returned 1 "Underworld Marshal's Procession Token"!] [Ding! White Impermanence failed to grab the red packet and gained 100 favorability toward you. They sent you a private message: "Hey, little brother, got any cola? I'll trade you a Soul-Capturing Lock for some!"] From then on, Chen Sheng begins an incredible life trading "junk" from the world of the living for divine treasures from the underworld! While everyone else is still struggling to get ahead, he has already become the underworld's one and only officially designated supplier from the world of the living!
