[Crossover] If I Don't Fill the Plot Holes, My Peers Will Die

As a transmigrating world-hopping traveler who writes for a living, Ruolv Beizhu considers himself a web novelist who has five impressive police officer friends from the same training class. Though he leaves plot holes everywhere and never fills them in, he still dutifully brings readers in every world a blurb and the first three chapters of web-novel fun. Though he often updates late, he's absolutely committed to never finishing a story. No matter what happens, he won't give the protagonist a perfect ending, until System: Thanks for using our Plot Hole-Filling Rescue System, you irritable writing bro who can do anything! Ruolv: ... System: As long as you write the protagonists' stories from each murder case into articles and earn money, your future is in your hands. Saving your fellow trainees from impending death will be a piece of ca... Hey, hey, bro! Bro!! System: Bro, that's your next novel's protagonist, Gin. You can't hit him!!! (screaming) Ruolv: What the hell, whoever's forcing me to write is dead! - Things to Know Before Reading - 1. No CP. 2. The protagonist is a wisecracking type. He has a golden finger, and apart from money, he has no feelings. It's all about having fun. 3. Multi-world hopping, one punch and they're down. 4. There are mountains of author-created headcanons, so enter at your own risk. 5. He pins anyone he can beat to the ground and beats them up. Those he can't beat turn around and beat him instead. A happy author needs to know when to yield and when to stand firm (chaos). 6. For now, the worlds include Detective Conan, Demon Slayer, Jujutsu Kaisen, Bungo Stray Dogs, K, and others. Theme: Seeking a way home by beating up the people who pay him.
