Intern doctor, Harvey York, hit rock bottom when his girlfriend betrayed him. After inheriting his family's medical and martial arts knowledge, his life began to turn around!

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."
