As a meteor threatens to destroy the world, Alfred Maxwell—an immortal cultivator of a thousand years—accidentally returns to the planet of Azure.While drunk, he destroys the meteor but also demolishes a tycoon’s spacecraft, forcing him to hide his identity to avoid legal consequences. At his mother’s request, he becomes the bodyguard for Serena Sutton, a wealthy heiress, though they get off on the wrong foot when he accidentally walks in on her bathing. When the Sutton Group faces a hostile takeover by Deacon Lowe and Serena is harassed at school by the spoiled Leo Ferrell, Alfred uses his immortal abilities to resolve each crisis—racing wheelchairs against sports cars and thwarting frame-up attempts in locker rooms. When Leo kidnaps Serena to force her mother to sign over the company, Alfred pursues them on a crane, stopping the kidnappers’ vehicle with his bare hands. However, the meteor fragments harbor an alien threat, and Julia Drake, who witnessed the immortal saving the world, is about to trigger new complications...

Urban security officer Alex Han is beaten to death by vampires. His father's lingering soul uses the Sun Seal to send him back to 1650, where he becomes a legendary demon hunter. Armed with future knowledge—repeating crossbows, gliders, financial futures—he slaughters the blood demons. He rescues his sacrificed aunt, snaps Dracula's neck, and pierces the thousand-year-old Vampire Lord's skull with three silver bolts. But victory comes at a price: all vampiric hunger floods into him, the golden seal transforms into a silver moon emblem, and an ancient "Night King" awakens in the East. The Empire's emperor is revealed as the Vampire Lord's vessel. Alex leads an army of half-bloods to storm the capital and personally breaks the emperor's neck. In the final battle, he uses the silver key to lock the Night King—a giant of pure fear—back into darkness. The curse shatters. Humans and vampires stand together in the sunlight. Selena rides east, saying, "When you return to your own time, I will be there waiting for you."
