Becoming a Swordmaster by Reading

Once a disgraced mage, Roden was a revolutionary magic theorist who redefined the foundations of magic with his genius intellect. But his life came to a tragic end—betrayed by a close friend. When he next opens his eyes, he finds himself in the body of Ernst Glockner, the third son of a prestigious swordsmanship family… a full 100 years in the future. Now thrown into the chaos of war and a brutal succession battle within his new family, Roden makes a choice: Survive—no matter what—as Ernst Glockner. And to do that, he’ll use a mysterious new ability: the power to master the sword just by reading books.
