Zhao Huan, a graduate student in the history department, traveled through time and became a young eunuch who was about to be executed with a cane. He pretended to be the eunuch in charge of writing and then read the imperial edict wrongly in public, causing an uproar in the court. At the critical moment, he showed the imperial seal with his backhand, and the civil and military officials in the court were stunned. Emperor Zhu Yonglie, who had been pretending to be crazy, suddenly laughed maniacally. From then on, the fake eunuch became the most trusted "madman" of the emperor. The Queen Mother Li Zhen arranged a killing plan, the chief assistant Zhang Juzheng secretly planned it, the commander of the Jinyi Guards Lu Lingxiao tried his best, and the palace maid Su Nianwei monitored closely. Zhao Huan relied on historical knowledge and modern means to deal with all parties on the tip of the knife, and gradually uncovered the shocking secret behind the Jade Seal.
