Lin Wan, a doctor disfigured on her wedding night when the God of War Yuchi Xiao carved up her face and skinned her, is reduced to a Gu slave. Bearing the bloodline of a sacred maiden from the Southern Frontier, she awakens amid heart-devouring agony and sets out on a path of revenge and salvation with her Golden Cicada Gu. The blind God of War Yuchi Xiao is caught in the mystery surrounding the face-cutting. After becoming a Gu slave, his body and weapons undergo a symbiotic transformation. Trapped between pursuit and protection, he witnesses Lin Wan tear out her heart and bury a city. The instant his sight returns, his regret burns through the heavens. From the battlefields of the Northern Frontier to the Gu lands of the Southern Frontier, from the Eastern Sea’s merfolk palace to the Buddhist kingdom of the Western Regions, both undergo layer upon layer of transformation. They are bound by bone-deep hatred and feelings that have yet to fade, caught in a world-shaking conspiracy controlled by Su Yue’er and an ancient apocalypse in which “the mountains and rivers become Gu.” When the flames of the Heaven-Burning Gu consume the mountains and seas, will they journey together to the afterlife, or burn their hearts and become gods? A blind war of betrayal, redemption, and absolute power sweeps across the eight directions.
