Commoner Kaelen deeply loves his fiancée Helen. For years, he has repeatedly drawn his own life essence to suppress the bloodline curse on her, willing to reduce himself to a frail wreck. Yet on their wedding day, he is betrayed by Helen and her new knight lover, and callously thrown into a perilous abyss teeming with ferocious monsters. On the verge of death, Kaelen accidentally activates the ancient altar of the Progenitor of the Vampire Clan, remaking his handsome physique and awakening the supreme divine power of the night. He returns to the royal capital wearing a mask, coming back with overwhelming strength and endless wealth, tearing apart hypocritical nobles and soundly thrashing his traitorous enemies. As layer upon layer of conspiracies are unravelled, he discovers that his years of sacrifice have been nothing but a scam. From then on, he turns completely dark, shatters the holy light, takes control of the abyss, and embarks on an extreme path of revenge that sweeps across the world.
