Cheng Huaixin, a graduate student in history, transmigrated into the body of the last emperor of Northern Yan. From the start, during a bloody upheaval at court, he personally captured the rebel leader Gongsun Shu, only to uncover a shocking conspiracy: Southern Chu had infiltrated Northern Yan with sleeper agents twenty years earlier. To break the deadlock, he had no choice but to enlist Gongsun Shu's adopted son, the cold-faced general Xiao Tieyi, and rewrite the Mandate of Heaven through the words of Shen Qingluo, daughter of the Grand Historian. The Northern Di wolf cavalry battered at the passes, the great clans obstructed him, and Southern Chu's agents remained deeply entrenched. Cheng Huaixin used his modern knowledge to plan every step, only to discover that every piece of history he rewrote opened another abyss behind him, one from which there was no turning back. And the blade in Xiao Tieyi's hand, ready to turn against him at any moment, was poised against his most vulnerable spot.
