In the year 1340 of the Shire calendar, there was still one year before the Lonely Mountain Expedition set out. At this time, the wizard had not yet visited the Shire, Thorin was still wandering, and the dragon was sleeping in the mountains...

This year, a human with the MC system came to Middle-earth.

So the high wall fortress was built overnight, and the golden wheat fields were endless.

The legend of the cube wizard spread in the wilderness.

Many years later, when the orc army was at the gates of the city, looking up at the infinite water pouring down from the sky, they were silent.

"Is this not playable?"

Luo Yi, a high school dropout in his original world, was isekai’d into the world of the Witcher 3. Starting out as a weak boy named Roy in the village of Kaer, Lower Posada, he was determined to grow stronger, no matter what it took. The first step toward becoming a legend was to kill. And his first kill was… a rooster. ‘You gain 1 EXP.’ Of course, Roy had his own cheat system like all the other isekai protagonists. His first step to becoming a legend started now…

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!
