Hu Weiyong, a modern-day graduate student in history, opens his eyes to discover that he has become Hu Weiyong of the twelfth year of the Hongwu reign—the last Chancellor of the Ming Dynasty's Central Secretariat, as recorded in history books. With the Empty Seal Case about to erupt, Tu Jie on the verge of exposing him, and Zhu Yuanzhang's suspicion reaching its peak, he finds himself in an apparently inescapable predicament. Without the slightest hesitation, the protagonist does something that leaves the entire imperial court utterly astonished and overturns everyone's expectations.
