Ling Ye was originally a hostage abandoned in the deep palace, carrying a strange poison, and his life was like a candle; Yu Jin was the God of War in the North, cold-blooded and taciturn, but he made an exception and raised his sword for him in a night of blood and rain. When the imperial power was in conflict and the dynasty collapsed, the two men joined forces to seize the palace when the moon was dark and the wind was high. They used poison for wisdom and an oath for the sword. Ling Ye reversed his destiny with his useless body, and Yu Jin protected him to ascend the throne with an iron-blooded heart. This is not redemption, it is revenge that burns in both directions - one wants to destroy this cannibalistic imperial court, and the other wants to build a throne for him that no one dares to bully.
