The play tells the story of mathematical genius Lin Zhaosheng, his daughter Lin Chaoxi, and high-IQ boy Pei Zhi, as they search for themselves in mathematical reasoning and dual time and space interaction. Lin Chaoxi's life was not satisfactory after graduating from the Department of Philosophy. She had the seeds of mathematics buried in her heart, but because she had long looked up to her father, Lao Lin, and her first love, Pei Zhi, two mathematical geniuses, she was not confident. It was not until she experienced two parallel time and space journeys that she burst out with power beyond imagination. Morning and evening came to parallel time and space for the first time. She was only twelve years old here. With the help of Lao Lin, she spent an exhausting summer vacation at the Mathematical Olympiad summer camp. She regained her confidence in mathematics and decided to take the initiative in life. During the second time journey, Lin Zhaoxi and Pei Zhi returned to their senior year of high school. As the two fought side by side, Lin Zhaoxi gained the courage to face life head-on. Back in the real world, Lin Zhaoxi was preparing for the postgraduate entrance examination in the Department of Mathematics while participating in modeling competitions to earn bonuses to support her family. In order to help Lao Lin, who suffers from Alzheimer's disease, recover as soon as possible, Lin Chaoxi and Pei Zhi jointly promoted the research on the P=NP problem and jointly climbed to the pinnacle of mathematics. At this point in the story, I closed the book day and night, and it turned out that this adventure was a story created by the novelist day and night.
