When Crisis Strikes: I Stockpile Like Crazy

The entire story takes place in a fictional world. Li Na has been having recurring nightmares about the apocalypse for a long time: extreme cold, extreme heat, earthquakes, plants and animals mutating, and humans changing too. As soon as she wakes up, she discovers that she has awakened the Myriad Worlds Exchange System and is told that the end of the world will arrive soon. From then on, Li Na starts frantically stocking up, while trading resources with her friends in the group. Rice, flour, cooking oil? Buy them! Buy lots.
