The undead vamp system

When the rift between worlds tore open, chaos descended upon Earth. From its crimson depths poured monstrous beings—beast demons, undead legions, and entities of nightmarish power. Humanity fought back with everything it had. Warriors, mages, and soldiers united under a single banner to defend their crumbling world. But no sword was sharp enough, no spell strong enough to stop the endless tide. In the end, humanity fell, their cities reduced to ruins, and their numbers dwindled to near extinction. Among the countless victims was Eric Alphonse, a kid who perished during the final assault. Yet death was not his end. Decades later, Eric awakened from his grave—reborn as something neither fully human nor truly undead. In the silence of a shattered Earth, a mysterious voice echoed within his mind, granting him the System—a gift and a curse that promised limitless power in exchange for endless struggle. Now, Earth has become a hunting ground where monsters and otherworlders roam freely, and the remnants of humanity hide behind fortified academies, training a new generation of fighters. As Eric steps into this broken world, he discovers that survival is no longer enough. His rebirth hides a greater purpose—one tied to the origin of the rift and the secret behind his resurrection. But as his strength grows and his blood awakens, so too does the darkness within him. With each battle, he edges closer to becoming the very thing he swore to destroy. Will Eric conquer the shadows of his past and rise as Earth’s savior—or will he lose himself to the monster within? The end of humanity was only the beginning.
