Lord of Flames

Qing Yan was once the young master of the Qing Clan—born with the legendary Dragon Bone, he was hailed as a martial arts prodigy the likes of which appeared only once in a century. However, in a ruthless bid for power, his stepmother forcibly extracted his Dragon Bone and transplanted it into his younger half-brother, Qing Siye. Stripped of his power, Qing Yan was reduced to a cripple; it was only with the aid of his childhood sweetheart, Wen Shuyue, that he managed to escape the Qing Clan. Yet, in the act of protecting him, Wen Shuyue was left behind—forever trapped in the past, ten years ago... Ten years later, Qing Yan returns to Yunzhou with a singular focus on two objectives: First: Vengeance. Second: To fulfill the promise he made to her a decade ago. However, a decree of marriage issued by the Sovereign of the Realm soon entangles him in a complex web of romantic intrigue involving two women.
