Delivery worker Lin Xiao was humiliated and comatose by a customer on a rainy night, and unexpectedly awakened the "double realm mirage body" sleeping in his blood. Whenever he falls asleep, he travels to the world of immortality and becomes the holy son worshiped by thousands of people. When he opens his eyes, he returns to a rental house full of cigarette butts. When the sword intent in the dream condensed into the green light on the fingertips of reality, the beauty in cheongsam encountered on the way to deliver the food turned out to be the Holy Maiden of the Medicine King Valley, the order notification tone on the mobile phone coincided with the frequency of the ancient sword art, and the female monk who practiced together on the cold jade bed last night used her status as the daughter of the group to complain that he was late for takeout - this absurd epic shuttled between the fairy and the market, unfolded with the sound of Meituan's notification tone and the sound of the sword piercing the air.
