A postgraduate history student transmigrates to the Yuanyou era of the Northern Song after an accident, taking over the body of a county magistrate who has been demoted. At first, he plans to keep his head down and get by, but his knowledge of modern history lets him foresee the many crises soon to face the Northern Song.
Faced with factional strife at court, threats on the borders, and a people sunk in poverty, Lin Yifeng rises from a lowly clerk, using his foresight and modern management skills to resolve crises and reform long-standing abuses. He introduces new farming methods in Jiangnan, modernizes the military on the frontier, and turns the tide at court.
But changing history is never easy. Resistance from conservatives, suspicion from reformers, enemies watching hungrily from beyond the borders, and the chain reactions caused by his changes to history's course all leave him treading on thin ice. More bewildering still, it seems someone else who transmigrated is secretly making plans...
This is a story about ideals and reality, wisdom and courage, affection and responsibility. If someone possesses knowledge beyond his era, can he spare this crumbling dynasty some bloodshed without changing the broad course of history? And when he realizes that every move he makes affects the fate of countless people in future generations, how should he choose?
