The newly transformed little water demon Zhu Lin has an adult body but a child's mind. He knows nothing about love, and finds certain important parts of himself so ugly that he nearly castrates himself. Together with the simple-minded divine beast fawn Zheguang, he sets off on an ordinary journey to uncover the past, only to get caught up along the way in a major event no one could have foreseen. One important character after another makes an entrance, and amid all the laughter and bickering, a grand story unfolds.
