Avatar: The Sword Saint

After the Avatar—the one who maintained the balance of the four nations—vanished, the Fire Nation launched its war. Nearly a century has passed, and the flames of conflict have spread across the world. Unable to bend any of the four elements, Ren was nothing more than an ordinary man. Left with no other choice, he devoted himself to the sword, training relentlessly while poring over ancient texts in search of the true origins of bending. Before long, however, that quiet and peaceful life was shattered……by a certain princess whose attacks had absolutely no sense of restraint. — Description from novelcodex.orgFull novel: Avatar: The Sword Saint — read the rest free on N​o⁠v​e⁠l​C⁠o​d⁠e​x⁠.​o⁠r​g⁠
