Three years ago, Xiao Jin, the king of Beique, fought bloody battles in the northern border, but was betrayed by his cronies, and 350,000 cavalry annihilated Huangsha. After the imperial edict returned to Beijing, he was reduced from a hero to a prisoner and was imprisoned in a deep house in Luoyang. Everyone thought that the evil dragon in the north had its claws broken off and was trapped to death in a cage. But no one knew that this oppressive silence was just brewing a thunder that would sweep across the world. When the cobwebs of conspiracy spread from the depths of the palace, and when the blood of old friends stains the court, the dormant lone dragon will break out of the cage, use sin as a blade and blood as a sacrifice to repay all the debts owed to him!
