In the 21st century, Xu Fei, a doctor of Chinese language and literature, accidentally traveled through time and became the second grandson of the Xu family, a five-year-old poor peasant, determined to change his destiny through the imperial examination. The grandmother of the family, Mrs. Xu, was biased and poured resources into the big house. Xu Fei planned to recite the "Three Character Classic" in public to shock Mrs. Xu, in exchange for the opportunity to deliver meals to Xu Wenyan and listen outside the private school. When delivering meals, he was appreciated by the master of Qian's private school, and he was officially admitted to school. He was also recommended to take the Tongsheng Examination, and changed the fate of a poor family with the imperial examination.
