I'm Not a Potato Sprite

One day, Fu Wensong found a young woman in his fields. She was not only beautiful but capable, too. She wasn’t afraid of hard work, and she helped him build a fortune and lift his family out of poverty. Fu Wensong often wondered who this young woman really was. Could she be a potato spirit that had come to life? To test his theory, Fu Wensong secretly watched her for a long time. In the end, he reached a conclusion: she had to be a fox spirit. Otherwise, how could she have bewitched him so completely?
