The End of the World, Surprise! the Zombie King Is Actually a Human?

(Before the end of the world begins, I wrote a lot in the first part, and there may be a lot of nonsense. If you don't like it, you can mark it out. Please don't spray it) Mu Qingge was inexplicably brought to a strange world. A system that exists in her mind and can materialize into a bird tells her that she must complete the tasks issued by this world before she can go home. Facing an unknown threat and a completely unfamiliar world, she didn't want to do any tasks at all. Moreover, she had no illness or pain in the original world, so why did she suffer like this when she had nothing to do? ... Okay, the system did give me a bit more. After all, this reward is very helpful for returning to the original world, and there is no loss if you don't complete the task. You can still go back, and the system has retained you, so just reluctantly stay. The next step is to stock up on supplies in advance. The space supplies provided by the system will expire, so stock up as you like and buy whatever you like. The original owner has plenty of money. But there are some major events in the big world that happen all the same, such as epidemics and the like, and medicines and the like need to be stocked up in advance. The next step is to buy, buy, buy, based on the amount of ten people, buy enough things to last several lifetimes. When the end of the world came, she saw very human dangers, but she also met someone who could give her back to him. (Not just people) (Hehehe, the author who has been missing for a year and a half is back, still alive, still alive, I am still alive!!!) (Although this is the second time I have written it, the author still remains stubborn. The writing may not be good. Please don't criticize me. Please, I love you.) (There are also some emotional ones that I don't know how to write, so don't spray, don't spray, don't spray!!! Say important things three times)
