Honestly trying to figure out the reading order for 'Omniscient Reader's Viewpoint' chapters from the wiki almost gave me a headache at first. The main complication is that the wiki often organizes information by in-story arc or by character, not strictly by the linear chapter sequence. You might click on the '73rd Demon King' arc page and see chapters 45-78 referenced, but then the 'Peaceland' arc section jumps you back to earlier chapters for context on Yoo Joonghyuk's earlier regressions. The character pages are even worse for sequential reading—the Dokja page will have spoilers from the final chapters right next to his introductory moments.
My method was to ignore the wiki's internal navigation for plot order and just use it as a companion. I read the webnovel sequentially on the translation sites, from Chapter 1 onward. When I hit a confusing reference to a past regression turn or a myth I didn't recognize, then I'd pop over to the wiki. I'd search the specific chapter number I was on, and the wiki entry for that chapter usually has a 'Previous Chapter' and 'Next Chapter' link at the bottom. That's the most reliable way to move forward linearly using the wiki itself, but it's clunky. Really, the wiki is an amazing resource for cross-referencing symbols and theories, but it's built like an encyclopedia, not a reading guide. I ended up with a dozen tabs open trying to trace a single plot thread, which was its own kind of fun but not efficient.
A solid piece of advice I stumbled on in a forum: find the wiki's 'Chapter List' page. It's sometimes buried, but it's a single, bare-bones list of every chapter from 1 to the epilogue, often with direct links. That's your true reading order. Everything else on the wiki—the analysis, the connections, the fan art—is best enjoyed after you've finished the story, or at least a major arc. I ruined a few major twists for myself by digging too deep into character pages early on. The sheer density of interconnected lore in ORV means the wiki is a maze; you have to accept you'll get a bit lost and just enjoy the process of discovery.
