During the Kaiyuan period of the prosperous Tang Dynasty, Yunhe, a white crane fairy boy who had practiced for thousands of years, returned to his natal crane Xueling. In order to protect the ancient fairy formation against the invasion of demons, he exhausted his fairy power and fell into a deep sleep. In 2025 AD, in a thousand-year-old cave deep in Huangshan Mountain that was split open by lightning, a man and a crane woke up in the dust and found that the world had been turned upside down. This is a warm and funny growth story about an ancient fairy bird making jokes, learning knowledge, making friends, finding similar people, and finally finding its place in the world in modern society.
