He Who Woke the Dragon Throne

Twenty years ago, the continent's most powerful force, the "Dragon Abyss Holy Fortress," was annihilated to the last person by the Void Cult, and its sole heir, Arthur, was rescued by a mysterious master. Twenty years later, Arthur—on the verge of completing his "True Dragon Divine Body"—follows his master's orders, disguising himself as a penniless groom with zero magic power as he heads to the imperial capital's Flying Dragon Ducal Manor to fulfill his marriage contract with the duke's daughter Seraphina, while secretly investigating the truth behind his grandfather's brutal death.
