Li Wangchuan, a history student preparing for the exam, woke up and became a down-and-out scholar during the Kangxi period of the Qing Dynasty. There is no system or golden finger. He only relies on the common sense and courage of modern people to succeed step by step in the academic field, the political field, and the battlefield. From being elected in the provincial examination to becoming a marquis and becoming a prime minister, he used modern wisdom to solve ancient problems and wrote a passionate official career that did not rely on fantasy. Everything changes in the dream, but I have no regrets when I wake up.
