Cui Xian, a doctor of sinology in 985, accidentally traveled through time and became an eight-year-old child from a poor family in Nancheng. When he was attacked by evildoers, he arrested the strong man, and his grandmother had difficulty selling her house. He recognized Pei Jian of the Pei family as his eldest brother to tide over the difficulties, coaxed him to save the prince when he was in school, and recognized the emperor as his godfather. Later, he used the emperor's power to fight bullies and was sponsored to go to Beijing. At the age of eight, he won three yuan in a row and became the number one scholar. He and Pei Jian were named marquis and prime minister, leading the family to counterattack.
