A yellowed ancient book and an undying obsession pulled the soul of Xiao Chenyu, a graduate student in the history department, into an era of war and turbulent mountains and rivers - the Great Xia Dynasty.
When he woke up, he was in an isolated city in the north. In front of him was the wolf-like Beidi cavalry, and behind him were thousands of people in danger. There is no cozy library here, only cold blades and desperate cries. The knowledge he once had on paper became his only weapon.
Assisting the young general who was ordered to do something in danger, he used strategies beyond the times and incredible conspiracies to forge his reputation in the furnace of blood and fire. From guarding the isolated city and training the new army, to defeating the Dilu and shaking the court, step by step he grew from an unknown person to a pillar that could control the world's chess game.
Powerful ministers are in power, aristocratic families are holding back, imperial power is on the sidelines, and foreign enemies are around. How should he move in this game of chess?
When the torrent of history rolls in, he chooses not to be a piece of dust drifting with the current, but to be the one who controls the direction of the flow - Changfeng in the North!
