Frenzied Stockpiling in the Apocalypse

Tu Xiaoxiao is reborn into a book about the apocalypse. A month after the end of the world, the original owner was so hungry that she went out looking for food, only to be bitten to death by a zombie without finding any. Tu Xiaoxiao decides to lie flat and stock up first. Buy, buy, buy; hoard, hoard, hoard. She buys everything she needs to use and eat.
