On the brink of death, he unexpectedly fused with the power of the Ancient Dragon Emperor, gaining formidable dragonblood power. Reborn, he led his fellow slaves in a rebellion against tyranny and uncovered a dark conspiracy hidden within the kingdom. Torn between vengeance and the duty to protect his people, Adrian rallied allies, saved his subjects, and launched a final challenge against Valen, who had stolen the throne—embarking on a journey to reclaim the throne and become a true king.
