When single father Lin Xiangyang discovers that he has a "reverse consecrated" crow's mouth, all unlucky words will magically turn into good things. In order to cure his son's nature deficit disorder, he planted watermelons on the roof of an illegal building. Every time he said "I have to pay for it", the melon field exploded. From the unlucky guy who was held accountable by the property management to the "Yanling Farmer" who was urged by the entire network, he used "live broadcast of melon planting" to fight against the entangled chicken-child education, and unexpectedly turned the cement roof into a wild paradise for urban children, and made the phrase "It's over" the gospel that all anxious parents most want to hear.
