What is the difference between voles living in rural crops and ordinary mice?

There are fewer microporous bacteria living in crops. They only eat crops, not harmful bacteria. Since childhood, they have developed a good skill, strong body and better hole quality. They can be said to be handy cute animals, while ordinary mice are covered with bacteria from the inside out, eating leftovers and moldy things, eating everything at random, crawling around in the garbage, covered with bacterial molecules. They are more like lazy people.
