In Chang'an during the prosperous Tang Dynasty, there was an inconspicuous "Anchen Town" in Yanshoufang of the West City. Its owner was a mysterious young man who always wore a moon-white robe. He possessed miraculous skills and walked around the world to slay demons.
For any difficult problems such as exorcising evil spirits or avoiding disasters, people can get help in Anchen Town by throwing a few pennies or bags of corn. The mysterious young man looks as gentle as jade, but he is never ambiguous in his judgment of good and evil. The good demon signs a contract, and by accumulating merit, he can enter reincarnation; the evil demon stains his blood and commits evil, and his soul will be scattered.
Along the way, Ding Wuyou also accepted several apprentices.
But no one knows that this savior who can solve all the difficulties in the world hides a thousand-year secret about "transformation" in his heart - when he saves all living beings, he is also saving himself. When the mysterious cases that appeared one after another in Chang'an City actually involved ancient conspiracies related to his life experience, the mysterious young man and the monsters' "road out of adversity" once again reached the edge of life and death...
