Shen Tuo, a doctoral student in the history department, woke up and became a down-and-out scholar in the troubled times of the late Tang Dynasty. With his knowledge that was thousands of years ahead of his time, he originally wanted to become a military advisor under Zhu Wen, but he was drawn into the whirlpool of feudal hegemony. He rescued the orphan girl Li Xingyue, but he didn't know that she was actually a Tang princess living among the people; he teamed up with the Pei family to target Pei Yan, but found that every step he took was changing the course of history. Huang Chao's defeat, Zhu Wen's rise, Sha Tuo's move south... He tried to end the troubled times with strategies, but was repeatedly countered by Cui Yin, Li Keyong and others. When Shen Tuo finally took control of the country, he was shocked to find that his name had already been written into the fragments of unofficial history outside of history books.
