When modern engineer Levi transmigrates into the body of the impoverished second son of a nobleman on the French border, with his elder brother dead and his father critically wounded, he finds himself with only three days to prevent his family's annihilation. A ruthless enemy is closing in on the crumbling castle; what will he do? Fortunately, fate intervenes. The [War Lord System] that comes with his transmigration grants him the ability to see through territory data and imbues his soldiers with unwavering loyalty. In the Burgundian War, a conflict that will reshape the European landscape, Levi will use his modern management skills to reshape the medieval army, building an ironclad force in an era when firearms are still in their infancy. From a border baron to the Black Duke of Paris, his iron hooves will ultimately shatter the shackles of feudalism!

The plan is to write three sections. First, the Austro-Hungarian Empire: how did an empire with a first-rate geographical location, advanced industry, and profound culture, seemingly with extremely high potential, reach its peak, and where did that peak lie? Second, how did the Russian Empire reach its zenith? Third, the Ottoman Empire or Italy (not yet decided). Join the book's group (878578959) for discussion.
