Rotating System in a New World

[Question: Describe some of the notable Calamities that attacked humanity.] [Answer: The Blond Knight, The Blindfolded Man, The Devil of Domination, and The World Breaker.] These familiar titles left Lin Fan a bit... concerned. "Just what have I gotten myself into?" If it weren't for the fact that Lin Fan's system can rotate every so often, there's no way he would be able to survive what is to come! [War System: Repel the Calamities and reclaim mankind's soil!] [Technology System: Develop AIs, obtain computational power, advance mankind!] [Expedition System, Sign-In System, One Piece System, Simulation System, Livestream System, Trope System, Cosplay System, MMO System, NPC System...] [System will keep updating with new selections for rotation.] -------------------------------------- AN: This is not a translation. This is a serious fanfic I've wanted to write for 2 years before finally pulling the gun. It will start off with some serious, some slice of life, before moving onto serious arcs with minor arcs dedicated towards SOL. The fanfic has elements of kingdom building, advanced technology, expedition into the unknown (Dark Continent HxH-style), sacrifice, omegaverse (multiple series inside of a single world), and of course, a rotating system. I've read too many fanfiction and originals off 69shu and mtlnovel that I've decided to just start writing some again. If you want to know just what type of story this is, you can check my inspirations below. Inspirations: One Piece, OPM, Fate, HxH, Kingdom, Lord of the Mysteries, Embers Ad Infinitum, Cyberpunk, The Mech Touch, Global Game: AFK in The Zombie Apocalypse Game, Arceus Pirate Tour (MTL FF), Warhammer 40k, Gundam, Made in Abyss, Naruto, I have a Super USB, World's Best Martial Artist, Final Fantasy 14, and more. I have always had a bad history with continuing novels due to my atrocious college situation but I'm nearing graduation so it shouldn't be an issue(?).
