Zhao Jun, the king of mercenaries, transmigrates to become the puppet emperor of the Great Chu. He is humiliated by the vicious empress at the start, then strikes back forcefully with modern soldier king tactics: eliminating traitors, taking control of the imperial guard, forming the Black Dragon Guard, pretending to build a leopard chamber to deceive the powerful prime minister Qin Yuan, going undercover to Jiangnan to thoroughly investigate the major cases of private salt and armaments, and finally using thunder bombs to crush the rebel army, completely seizing back imperial power.
