Three years after Zhang Ping'an married into his wife, he was regarded as a waste by his father-in-law's family. He cooks, repairs furniture, and takes care of his children with a smile every day, never leaving a shabby wooden box in his hand. No one knows that this wooden box is connected to an ancient treasure house, which contains treasures and magic weapons that can subvert the world. But he never used it. His brother-in-law laughed at him, so he took out a rejuvenation pill and cured his mother-in-law's old cold leg; when his neighbors made things difficult for him, he took out a luminous pearl and lit up the entire alley. At the end of the three-year period, when the real enemy came to the door, Zhang Pingan opened the wooden box and took out only a shield to protect his wife and daughter. He said: "No matter how good the treasure is, it is not as good as a whole family."
