Zheng Mobai, a modern financial genius, accidentally traveled to the Great Xia Dynasty and became a poor scholar with nothing to live up to. His iceberg personality in his previous life made him disdainful of studying in the military, but he unexpectedly discovered that the imperial examinations in this world could depend on the eight-legged stereotype of Shi Wen to determine life or death. What's worse is that Zhao Mingyuan, the son of the local richest man, is not only his love rival, but also targeted and framed everywhere. However, what Zheng Mobai didn't know was that the modern knowledge base of "Sikuquanshu" he carried with him was awakening in his mind. While everyone was still reciting ancient classics, he had already used modern logic to decipher the lifeline of the imperial examination. The local magistrates were all shocked by his policy. Zhao Mingyuan panicked! He used his family's power to bribe the examiners and wanted to make Zheng Mobai lose his reputation in the provincial examination. But Zheng Mobai smiled slightly. He wanted to use modern financial knowledge to smash this decadent imperial examination system. Under the iceberg is a torrent of wisdom that can subvert an era.
