Thousands of years ago, the Dragon Clan Emperor disappeared mysteriously during her coming-of-age ceremony, and has since become a major unsolved case in the fairy world.
Yi Chunxiao, a confused and naughty fisherman's daughter, became a master of a stinky Taoist priest to learn magic. She met the wandering immortal Fu Yunchuan by chance. Not only was her master beaten to death, but she also became his cheap apprentice.
Is the love between master and disciple immoral? Well, Yi Chunxiao, I will expel you from the school as a teacher.
The water of the Forgotten River has been flowing for thousands of years under the Dragon Palace ninety thousand miles under the sea. Did it turn out that the water of the Forgotten River actually existed for her? Forget the river, forget the river, forget Fu Yunchuan.
Forget the river, forget the river, forget each other and look back, it has become a river.
