Traveling to the End of the World a Hundred Years Later

[No CP, system, superpower, strong woman in the end of the world] Xie Jingzhu was originally just an ordinary female college student. Once she traveled through time and woke up, she found a world a hundred years after the apocalypse, and was bound to an apocalyptic survival system. I originally thought I was simply traveling through time, but after encountering a series of events, I discovered that this time traveling was not as simple as I imagined. The best player in the league? Orc Guardian? The big boss behind the scenes in Taoyuan? One of the five gods? Everyone: Who are you? Xie Jingzhu:? ? ? (Apocalyptic survival, zombies, orcs, and hotel management buffs are all stacked up!!!)
