Six years ago, Xiao Duo’s brother was murdered on the streets of the capital. From that day on, Xiao Duo swore revenge against those responsible for the murder. His journey has taken him to the pinnacle of power: he is now the head of the Zhao Ding Division and has become the emperor’s right-hand man. But revenge—not power—is what drives him, and he will not rest until those responsible for his brother’s murder are dead. This has led him to conspire with the strong-willed Fu Wang. The two men have forged a pact that allows Fu Wang to sit on the imperial throne for the time being, even though an empress hopes to seize power through her own intrigues. By law, the former emperor’s concubine, a young woman named Bu Yun Lou (Chen Yu Qi), should have been killed and buried alongside him. But Fu Wang takes a liking to her and secretly orders that she be spared. He asks Xiao Duo to look after Bu Yun Lou for the time being. But Xiao Duo senses he can take advantage of this situation and devises a way to use the former concubine to help him exact his revenge. Yet fate intervenes when he begins to feel drawn to this extraordinary young woman. Can love truly quell his thirst for revenge?
