A delivery boy who comes from a remote mountain village to work in the first-tier city "Jiangcheng" wears an old T-shirt that has been washed white and rides a second-hand electric car. He is ridiculed for being "rural origin" and "poor appearance". In fact, he is the inheritor of the ancient chaotic Taoism. He has learned "Earth Fangzi" (actually the basis of cultivating immortals) from his grandfather since he was a child, and deliberately hides his strength.
