- Description from Novelupdates

I reincarnated into a fantasy world. Since I somehow got born again, I resolved myself to live diligently once more. But, putting that aside, my entire village burning up and disappearing when I’m 8-year old f*cking crossed the line. F*cking shit-f*cking crossed the line!

In a world without gods, where the laws of magic are written by the mages themselves, balance is fragile, and darkness reigns. Multiple dimensions surround it, watched by beings with dark and greedy intentions. This is a magical universe, unstable, marked by constant changes, betrayals, and bloodshed. At the center of it all, an ordinary man emerges, carrying a biochip capable of deep analysis and data recording. With it, he embarks on a relentless journey of genetic enhancement, seeking to ascend beyond the limits of existence. Without divine protection, without charms to shield him or overwhelming powers, he must survive in a world where threats are ever-present, and the fight for survival is relentless. Here, the only rule is to conquer or be consumed. A dark fantasy filled with dangers, evolution, and the relentless pursuit of supremacy.

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.

It’s really an egg! Damn it, what kind of monster have I become? Did I fall into Hell instead of making it to Heaven??

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!
