Dayu, a mocked archaeology loser, stumbles on an ancient sword and awakens as the Dual-Vein Descendant—heir to both light god and dark primordial blood. Bound to Yaoji, a trapped goddess-spirit inside the sword, he must stop the villain Shangjun from reviving the dark ruler of the universe. With mythic beasts, cosmic gods, and forbidden power, Dayu rises from zero to hero. He fights to control his chaotic bloodline, protect his lover, and save all realms from eternal darkness.
