Lucian, the supreme dark king who once ruled the dark-blood clans, seals his mighty power and lives an ordinary mortal life in seclusion. He quietly guards Silvia, a tough single mother who knows nothing of the supernatural world, and their 5-year-old daughter Luna. When the arrogant White family, a vengeful ancient dark-blood clan, threatens Silvia and Luna and launches endless hunts by ancient blood laws, Lucian breaks his seal completely. He defeats the clan’s elites step by step, exposes the century-old lies of the White family, crushes its century-old tyranny, and finally protects his family and rebuilds a fair new order of the dark-blood world.
