Ratman's Survival Guide to the Apocalypse

I lay on a bed made of stacked cans with a latex mattress on top, looked at the supplies all over the room, and let out a long sigh of relief. Wow, I finally finished everything. I, Lu Xiangxiang, was a female college student who was pushed to the pile of lost food by her sister as bait after more than a month of escaping from the apocalypse. Haha, but, I somehow came back to life and was reborn a month before the end of the world. Isn't this going to cause trouble?
