A top research scientist dies laughing after getting carried away, then transmigrates into the role of a vicious, lazy, greedy cannon-fodder villainess.
As soon as she transmigrates, she faces drought and famine. She hears there will also be earthquakes and snowstorms later, but with her storage space in hand, she stays calm.
As they flee famine, she latches onto the future regent. When he suppresses bandits, she empties their granaries. When he punishes corrupt officials, she empties theirs too. She keeps gathering supplies as they travel, and just as the famine seems to be ending and she’s about to enjoy a carefree life of her own.
