Zheng Nanke, an ordinary single dad, rents a house in the city with his five-year-old daughter and makes a living by delivering food. He was exhausted during the day, but after putting his daughter to sleep at night, he always had the same strange dream - there was an ancient academy in the dream, and the bookshelves were filled with yellowed ancient books. At first he thought it was just too much pressure, but one day, he accidentally opened one of the books, "True Explanation of Luck", and the next day he actually picked up a lottery ticket worth 100,000 yuan in the trash can. From then on, Zheng Nanke discovered that as long as he fell asleep, he could "endorse" in the academy, and each book could bring a real-life gift of luck: "The Art of Fortune" allowed him to help the old neighbor's lady carry groceries, and the old lady turned out to be a long-lost rich relative; "Baoguang Jue" allowed him to find priceless antiques at the flea market. But "luck" is a limited resource. Every time he takes away a piece of it, other people's luck will decrease. Soon, he attracted covetous people - some were eyeing his "cheating" ability, some were bankrupted because of being deprived of luck, and some discovered that his daughter had a deeper secret. This dad, who seems to just want to lie down and be a good-for-nothing, has to get involved in a battle for luck that spans three realms in the daily gaps of boiling milk, coaxing him to sleep, and working.
