The Great Ning dynasty has been at war with the northern nomadic tribes for sixty years, and border military spending has nearly bankrupted the treasury. Lin Mu transmigrates as the son of a border garrison household, with no strength, connections, or money. He discovers that military logistics in this era are a complete disaster: food is wasted, horses drop dead, and weapons rust, all because transportation and storage are managed so poorly. After he helps the supply corps redesign its routes, the survival rate of warhorses across the entire northern frontier rises by thirty percent. His achievements carry him step by step from the forage office to the Ministry of War, from the local level to the imperial center. In a way no general could have imagined, Lin Mu becomes the key to victory on the battlefield. He isn’t there to fight the war; he’s there to “fight the war’s logistics.”
