Jiang Jinyao was originally a doctor of modern history, but when he opened his eyes, he was transformed into the deposed prince of the Yin Dynasty who was demoted to the frontier. He was holding an imperial edict to execute loyal ministers in his hand. That night the red flames burned the imperial edict, and he brazenly rewrote the edict and went against the will of heaven. Lu Shulan, the cold-faced Minister of the Ministry of War, was ordered to track down the real culprit of the fake edict, but he discovered in the fog that the pen used to rewrite the imperial edict was exactly the same as the ink left by his late father. The two went from confrontation to temptation, from suspicion to conspiracy, and a political storm ignited by blood and fire quietly tore apart because of this tampered imperial edict - what he changed was the edict, what he kept was his life, and their paths were destined to walk side by side on the blade of conspiracy and truth.
