Oath to Guard the Borderlands

Liora Baker, the rightful saint of the Miao Borderlands, is usurped by her senior sister and exiled to the northern border. As a Convicted Female Captive, she meets Lucian Voss, a war god framed and left disabled. She uses Gu techniques to detoxify him, outwits invading enemies, and helps him regain military power; he protects her as she seeks revenge and quells unrest. The two join forces to take down traitorous generals colluding with enemies, reclaim Liora's position as saint, and eventually guard the border together, forging a legendary tale.
