MTL - From White Box To Supervision - Chapter 208 Xin Haicheng proposes

Aether Moirai was never meant to be free.Born from the final spark of the Abyss—a forgotten god’s last act of rebellion—he is the last vessel, a boy whose powers grow stronger the more his mind fractures. Bound by the Codex, a system that can rewrite history itself, Aether is hunted by worlds that fear what he might become.The Infinite Library has always been his home—a labyrinth between worlds where every book is a living realm, and every story is a battlefield. But when the tales begin to warp, birthing monsters and rewriting entire histories, even the Library’s endless shelves can’t protect him.To survive, Aether must step into dangerous books where myths breathe, legends bleed, and the wrong choice can erase you from existence. Each journey brings him closer to the truth of his creation—and the author who penned his fate.He is not the hero of these stories.He is the flaw in every one of them.

Roy’s life was nothing special. The only thing commendable was the last few moments when he saved a mother and her child from a drunk driver.

Join Roy as he ventures through various worlds with the Custom Made Demon King System—a system that allows Roy to draw anything he can imagine and create it through exchanging souls!
