I Reincarnated into Another World as a Blood Mage

Alex Mercer, a 24-year-old hematology prodigy, was obsessed with the secrets of life hidden in blood. Brilliant, stubborn, and a little unhinged from years of cutting-edge research, he lived for the lab—until the night he died saving a couple from a knife-wielding madman. As his vision faded and blood poured from his own body, Alex thought it ironic: a man who spent his life studying blood, now dying by it. But death wasn’t the end. Alex awakens in a grotesque, pulsing realm of crimson, face-to-face with the Goddess of Blood. Moved by his sacrifice, she grants him a second chance—in a fantastical world where blood is magic, and his knowledge becomes power. She blesses him with a terrifying, forbidden gift: Blood Magic—an ancient art outlawed for its overwhelming strength and cost to the soul. Reborn beneath a tree in a serene forest, Alex begins a new life filled with magic, monsters, and madness. He joins an adventurer’s guild, explores deadly dungeons, and battles corrupt nobles, cults, and gods. But as his reputation grows, so does his legend—and his list of lovers. From demon queens and runaway princesses to commoners and goddesses, his harem blossoms with powerful women drawn to his darkness and charm. Yet love is no shield. When enemies threaten those he holds dear, Alex becomes a whirlwind of bloody vengeance. He’s not the hero this world wanted. He’s the antihero it desperately needs. Fueled by blood, haunted by humanity, and entangled in comedy, romance, and chaos, Alex carves his place into legend. But every drop of blood he spills pushes him closer to something darker. Will he remain human—or become the greatest (and most feared) Blood Mage this world has ever known?
