The main story is complete. The comments contain spoilers, so if this is your first read, we don't recommend scrolling down. Thanks for reading. I probably won't be checking comments anymore. Feel free to send me a private message if you need anything. [Blurb] In his previous life, Duan Yunyang was a bestselling mystery novelist, famous far and wide. Sadly, he died far too young. On January 1, 2019, before the launch of Duan Yunyang's new book, he was found dead in the dressing room. There was no blood on him, but he had stopped breathing. People had all kinds of theories about the cause of his death. Some said he died of a sudden illness. Others said he was murdered. And some said the Devil had reached out and dragged him into a dark abyss. Floating in midair, Duan Yunyang had this to say: "Sorry to bother you. I was just kidnapped by a System by accident." Reading notes: 1. Plot-driven, with a somewhat unusual writing style. 2. The protagonist's snark is level ten. He's a professional mood-lifter, has no romance, and comes with built-in detective skills. 3. Quick transmigration through small worlds, all of them fictional. 4. Some stories are inspired by real cases. These will be noted in the author's comments. Anything not marked is purely coincidental. We pursue the truth tirelessly not only to give the victims an answer, but also to give this world an answer. The truth is never late. Theme:
