For thirteen years, the secret guard followed him everywhere, and the young master and his bodyguard were separated in the flames of war. Three years later, his homeland was destroyed, and he was forced to step into the enemy's imperial city as a hostage. However, he was shocked to find that the emperor who sat on a dragon throne and was in charge of life and death was actually a loyal servant who had disappeared from his memory. The sharp blades that were once side by side have now become the cold light hanging on the neck - is this reunion of the monarch and his ministers a redemption of old friends recognizing each other, or a more cruel trap?
Intention: The reversal of fate
