Lin Fu, a modern master’s graduate in military engineering, unexpectedly transmigrates to the tenth year of the Jiading era in the Southern Song. Mongolia is fighting Western Xia, the Jurchen army is raiding Huaixi, and the court is under the control of Shi Miyuan. Jiangnan is barely hanging on. Lin Fu becomes a young Song captive on the Huaixi battlefield. As soon as he escapes, he finds himself trapped between the Song and Jin armies.
He has no supernatural powers or powerful backers, only knowledge from a thousand years in the future. First, he improves the counterweight trebuchet to defend Haozhou, then develops gunpowder weapons to drive back the Jurchen. He rallies local militias along the border and outmaneuvers powerful officials at court to secure their support. Lin Fu knows the Southern Song’s weakness is rooted in its own rot: he must fight Mongol and Jurchen cavalry on the battlefield while taking on the capitulationists at court; he must strengthen the military with technology and win the people’s support through reform. This time, he will make sure the Jingkang Humiliation never happens again, bring the Sixteen Prefectures of Yanyun back into the fold, and shatter the label of “Weak Song” as he forges a powerful dynasty with his own hands.
