Return of Sanxian

A dream lasts for a thousand years, is it a dream or true? Sanxian is neither an immortal nor an ordinary person. He is somewhere in between. He does not cut off ordinary thoughts, does not respect the way of heaven, is both good and evil, and only cultivates his own self. When Chen Yi opened his eyes, it was the class in his memory... Asked for three thousand years, the path changed overnight. Is all this a dream or reality?
