I Transmigrated to the Apocalypse and Opened a Hotel for a Carefree Life

[Post-apocalypse + strong female lead + hotel upgrades + System + no romance] Yu Li took System 666 with her as she rampaged through various small worlds, setting a new record for the shortest time to complete a mission in the Villain Group, then happily began her retirement. Who could have guessed? The useless System came knocking again, claiming that the Heavenly Will of an apocalyptic world had sent out a plea for help. Yu Li: Are you kidding me?! I'm in the Villain Group. Isn't this the kind of job for the Redemption Group? System 666: Well, the Redemption Group has had a few problems lately~ The higher-ups are holding a meeting to educate them, so they're short-staffed~ After a comprehensive evaluation, the Main System decided you're the most suitable (and least busy) Host for the job. Yu Li: I'll have to politely decline. System 666: My beautiful, kind, and powerful Host~ Please~ There'll be a generous reward when this mission is over! Yu Li: How generous? System 666: The Main System said you can pick whatever you like~ Yu Li: Then what are we waiting for? Let's go! Natural disasters, zombies, human nature. Who pushed you into hell? Is the hotel that appeared out of nowhere a place of salvation for humanity, or a comforting illusion before death?
