It was the eighth month after an unknown virus outbreak, with hordes of zombies roaming the city. And she was living in the city center! Thank goodness! She had been bound to a cosmic management system and opened a grand hotel in the city center. From then on, the cosmic hotel became the safest refuge in this apocalypse, a sacred place everyone longed for. Just when she thought she would spend her whole life in this world, the system unexpectedly took her to ancient times, extreme weather, ocean disasters, and various other apocalyptic worlds. Let's expand our "cosmic enterprise" to every apocalyptic world! [In the initial apocalyptic world, level 2 crystal cores can be exchanged for 200 level 1 crystal cores, level 3 for 400, level 4 for 800, and so on.]
