A man is reborn into the world of Avatar: The Last Air Bender as a waterbender from Katara's tribe. Best of all, he was the same age as her, and he had a system with him to help.He knows the future and a system that lets him continuously get stronger by completing quests or long-term missions, as well as giving him the ability to copy abilities from others for himself. He will become invincible in the world of Avatar, even more so than the Avatar himself.

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!

Lin Mu was pushed down the cliff, but he did not die and arrived to a magical world instead.

A huge python with wings and can fly, alright, just think it as the legendary Mayan Snake God;

A gigantic centipede that can fly in the sky, alright, he kinda seen it before in ‘Journey to the West’;

A mighty big wolf with a body as humongous as an elephant, en, just think it as a mutant;

….

Although the animals in front of him were a little strange, they are still animals but why did all of you suddenly turned into humans? Coming across wild beasts, Lin Mu still can accept it, but coming across ‘*yaojins’, Lin Mu became . . . . . . excited instead. What? You guys are the infamous drifter beastmen? I don’t know anything about that. You guys did a lot of heinous crimes? I don’t see that either.

And so, Lin Mu began a hard but satisfying life of building a home in a another world.

*Yaojin/妖精 doesn’t have a proper English equivalent word. The nearest meaning would be supernatural being or Yokai (Japanese).
