Dark Old Demon

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!

Custom Made Demon King

Roy noticed the intentions of Astral and the others almost instantly.

To Roy, he could not let the alliance army kill Rafaro for the time being, so after merely hesitating for a second, Roy suddenly whistled.

Upon hearing this whistle, Fat Tiger, who was in the midst of mowing down the iron golems, immediately pricked up his three pairs of ears and looked up at Roy. When he saw Roy point at Rafaro, he immediately understood what Roy meant, so he abandoned the slow-moving iron golems and jumped into the air. He spread his wings and flew toward Rafaro.

Boom! When Fat Tiger was landing, he directly threw himself on an adult green dragon and dragged it down with him!

Fat Tiger was now over thirty meters long, almost the length of the largest blue whale. Moreover, he weighed more than 150 tons. With such massive weight, it was not difficult for him to drag a green dragon down with him.
