The Dayao Dynasty fell. When the smoke of war finally cleared, the new Yong'an Dynasty rose, peace reigned throughout the land, and the people pledged their allegiance.
But the two young men who survived the ruins never believed in a fate ordained by heaven.
A cool-headed, restrained younger powerbroker, fiercely loyal and protective, bears the bloodline of the fallen dynasty. Lying low in the new regime, he carefully plots each step, willing to stand against the whole world for one person. A brilliant, inscrutable detective with a calculating mind wields ingenious investigative methods to solve the land's most baffling cases. Meticulous, ruthless, and vengeful, he never shows mercy when he strikes.
They knew each other as boys, then parted one day and were separated by the chaos of war. Years later, they reunite amid the shifting currents of the new court, bound by fate to stand against each other, trading barbs as they walk side by side.
Their long road to revenge and the truth unexpectedly draws them into four bonds that will entangle their lives forever.
