In the Apocalypse of Natural Disaster, I Rely on the Sign-In System to Win

When she woke up, Xuan Ye found herself in a strange place. Then she discovered that the world was plagued by natural disaster viruses. Human beings moved to a high-walled city to live in. The city left behind was invaded by exotic plants and mutated beasts and turned into ruins. This is clearly an apocalyptic era! She is just enjoying reading novels at home. Why is it her turn to be involved in such a time-travel trend? Now that I have come, I will make my way in this apocalyptic world and live a better and more stable life than others! In this apocalyptic world, Xuan Ye holds a sign-in system and can sign in wherever she goes. Exotic plants and mutated beasts meet Ye Xuan for the first time... Exotic plants: Humans don't hide in their own nests well, but they actually dare to come to the territory of our exotic plants, catch them and eat them! As a result, what was eaten was the fruit of a foreign plant... The exotic plants and mutated beasts that have spent time with Ye Xuan: Where did the devil come from? Take her away quickly!
