Rebirth of the Demon Lord: I Built My Own System

​"To reach the pinnacle, I must live again. But who said I had to start from nothing?" ​Dusk, the dreaded Demon Lord of Darkness, was tired of the ceiling. To surpass his limits, he didn’t just pray for a second chance—he engineered one. Before his soul departed, he crafted a Sentient System designed for one purpose: to skyrocket his growth and reclaim his throne in record time. ​Now, he awakens in the body of Abel, a lowly Apprentice Necromancer with failing talent. ​To the world, he is a weakling playing with bones. To the System, he is a god in the making. While other mages struggle with basic mana manipulation, Abel is already rewriting the laws of death, mastering the arts of the soul to surpass the limits of his original life. ​It is the perfect disguise... or so he thought. ​Deep in the shadows of this new world, entities from his past are beginning to stir. Old allies and ancient enemies are crossing the boundaries of time and space, seeking the soul of the man who once plunged the world into shadow. ​The hunt for the Demon Lord has begun. But they are about to learn a terrifying lesson: Dusk hasn't just returned—he’s evolved.
