Zhang Tiezhu, a young man from Northeast China, wakes up one day to find himself transported into the body of the most miserable puppet emperor of Great Yue. Powerful ministers control the court, murderous plots lurk throughout the imperial harem, and the common people suffer terribly. While others advise him to endure and keep a low profile, he chooses to use his straightforward Northeastern personality and modern way of thinking to overturn the old rules. He punishes corrupt officials, solves bizarre cases, reforms the military, and improves people's livelihoods, bringing the entire court firmly under his control. Noble Consort Lin Wanru stands alongside him as they overcome one crisis after another, while Eunuch Cao secretly protects him. But when the imperial clan, powerful aristocratic families, and enemy nations join forces to force him from the throne, Zhang Tiezhu slams his hand on the table and declares, "In Great Yue, I call the shots!"
