Delivery rider Lin Yuan is actually the supreme immortal who has reversed time and space and returned. He travels through the city delivering food during the day and breathes out thin spiritual energy at night. His bank card balance is less than 7,000, but he has to repeat the three thousand years of spiritual practice. When the rich young man complained that he was overtime, and the guests scolded him for soiling his silk nightgown, no one knew that this blue knight, who had received bad reviews, once wanted to destroy the stars and bury the fairy king with a snap of his fingers. In this life, he just wants to save money to buy a house, cure his mother's illness, and occasionally take urgent orders to earn some extra money. Until that day, he delivered takeout to the penthouse, and the person who opened the door was the Taoist monk who died for him in his previous life.
