Ke Yang, a young Chinese boy studying in Romania, falls in love with the vampire girl Victor Susanna. The good times did not last long, and the Romanian vampire royal family launched a war against the vampires of the Victor family in order to seize the "sacred objects" guarded by the Victor family. On the battlefield, in order to save the seriously injured Ke Yang, Susanna injected vampire venom into her lover's body, causing Ke Yang to transform into a vampire and survive. The weak Victor family was defeated and family members died one after another. Susanna tried her best to cover Ke Yang and escape from the battlefield. Before she died, Susanna handed the "sacred object" to Ke Yang and told him that the "sacred object" should not fall into the hands of the royal family. What is it that the Victor family should protect at the cost of their own destruction?
Ke Yang returns to his hometown of Yecheng (Haikou City) with this item. He will follow Susanna's last words and hide the "holy item" in an unknown place. Ke Yang thought that when he returned to his hometown thousands of miles away, the situation would calm down temporarily, but unexpectedly his whereabouts were leaked and a group of werewolves followed him. The werewolves were eager to get the items that Ke Yang had, so they kidnapped Ke Yang's friends as a threat. Ke Yang thought he would fight alone, but accidentally met a human girl who claimed to be a "Demon Conqueror". While Ke Yang and others were fighting with the werewolf group, the powerful Romanian blood royal guard arrived quietly.
Can justice defeat evil? How bumpy will the process be? What kind of power does the holy object in Ke Yang's hand possess? Why did the Victor family suffer such disaster? What role do humans play in this foggy world?
