Wang Yuanfeng was born in a family of officials. He did not love money, fame, or the romance of men and women, but he had a special liking for solving mysteries and solving cases. Wang Yuanfeng accidentally saved the sealed fox fairy Xiaocui. Xiaocui married him to repay her kindness. Wang Yuanfeng was not smart and did not like women, so they shared a room but slept in different beds. Xiaocui was eccentric and often made fun of Yuanfeng, which gave Wang's mother a headache. Unexpectedly, Xiaocui's pranks helped the Wang family avoid the frame-up of Wang Jijian and dealt with corrupt officials. Wang Yuanfeng was therefore supported by the people and became a county magistrate. He was an upright and honest official. With the help of Xiaocui, he solved many strange cases, and the people called him "Daxian Yamen". The good times did not last long. Xiaocui left Yuanfeng because her time limit had expired. Yuanfeng, who loved Xiaocui deeply, fell ill and Xiaocui could not bear it. She cast a spell to make Yuanfeng forget about herself and fall in love with the daughter of the Zhong family. One day, Yuanfeng accidentally opened the treasured portrait and remembered what Xiao Cui looked like in the past, and burst into tears.
