When Xie Qiao heard what the shopkeeper said, she understood a lot better now.
Shopkeeper Chang looked at the girl and thought she must be a little naive, he then explained, "The sight of the rats causing a disaster is scary. I've seen it once in my early years. Those rats appear in groups, they're fearless no matter day or night. Inside the house, whether it is wood or porcelain, almost everything would be eaten. Even the house can't be preserved, not to mention the chickens, ducks, cows, sheep, and farms.
"The crops that the rats had eaten would be barren in the blink of an eye. Moreover, the rats are fearless of people, and there were many people who were bitten to death by the rats. Fortunately, the scope of this rat disaster was small. Otherwise, the imperial court would be in a terrible state. There would be more disaster victims outside the capital."
Shopkeeper Chang sighed.
