Jade Qilin of the Great Song

Zhao Donglai, a modern history and military enthusiast, wakes up one day to find himself as Lu Junyi, a wealthy merchant from Daming Prefecture in Hebei. The original 'Jade Qilin' was unmatched in staff combat, but his mind now holds a script of the next thirty years of history. Before him lies a corrupt court, restless jianghu, and the rising Jin Empire. Only fifteen years remain until the Jingkang Incident. He decides not to be the fool tricked into joining the Liangshan outlaws, nor the pawn poisoned by treacherous ministers—he will be the one moving the pieces on this grand chessboard. He recruits the Liangshan heroes, suppresses the Fang La rebellion, and gathers Yue Fei and Han Shizhong under his command. He reforms the military, rectifies the ills of the times, and steadies the tottering empire. When the Jurchen cavalry tramples the Yan-Yun region, he will make the backbone of this era stand tall once more. This is the story of a Jade Qilin holding up the sky. — Description from novelcodex.org
