The emperor died, and Zhao Che, the king of Huai'an, was ordered to assist in the administration. However, rumors suddenly spread in the capital that "the King of Huai'an committed regicide and usurped the throne." At the same time, border generals frequently moved around, and the Queen Mother's relatives' group tried to listen to politics behind the scenes. Zhao Che, holding the sword talisman in hand, discovered that the real "Wuyingwei" did not all respond to him, and seemed to have been divided internally. The main plot is clear: Zhao Che must protect the young emperor amidst court attacks, military threats and assassination traps, while finding out the truth about the death of the old emperor, integrating the divided "Shadowless Lieutenants", uncovering the real enemy hidden in the fog, and stabilizing the new empire.
