Xu Wei, a child prodigy in the south of the Yangtze River, was able to write poems at the age of three and write at the age of five. However, he failed the provincial examination three times in a row. Outsiders said that he had exhausted his talents, but they did not know that he had already discovered that there was shocking fraud hidden in the imperial examination room. Every time a test question is leaked, it points to a mysterious organization called "Qingyun Society" in the capital. In order to find out the mastermind behind the scenes, Xu Wei deliberately failed the exam, sneaked into the examination room as a down-and-out scholar, and dealt with fellow examiners, the examiner, and even the powerful officials of the dynasty. He battled wits with criminals in the examination room, borrowed a knife to kill someone in the court, and gradually uncovered the shady story of the imperial examination that shocked both the government and the public. Finally, in the palace examination, in front of the emperor, he used 13 test papers and 37 witnesses to fully present this ten-year imperial examination fraud case.
