Infinite: The Whole World Enters the Land of Runes

[Infinite Flow + Ladder Rankings + Faith-Based Professions + Time Reversal + 66 Professions + League of Legends Story Setting] That day, everyone around the world entered Runeterra. From then on, everyone had to travel through one dungeon after another. These so-called dungeons were not fabricated trials. They were real events that had once taken place in Runeterra: history brought back to life, and fates that had long since been sealed. Players could enter and bear witness, but they could not change any outcome. At least, that was what everyone believed at first. Until one day, a name began circulating across Valoran, a name that should never have existed in "history": Qi Mofan!! "Hello, I'm Qi Mofan, and my profession is Rewind Marksman!" "What? You're saying my profession is Historian?" "Oh, that's the profession I had in my second run!" "The me from my first run never lies!" League champions who have appeared in dungeons so far: Jinx, Fiddlesticks, Ashe, Pyke, Malzahar, Kai'Sa, Pantheon, Aatrox, Yasuo, Taliyah. Not overpowered, not pure wish fulfillment. One female lead or no female lead. (The author has already completed five books, so readers can dive right in with confidence.)
