A young man sat on a chair and looked out at the ocean. With one wisp of Spirit Qi, he could point anywhere on this vast and expansive world, pointing at any place that didn’t look right.

Someone once became the last one to wield a knife that could decapitate huge dragons and bathed in dragons’ blood. Someone once loved treating others to chicken soup, so he kept nine phoenixes in his backyard.

Someone once sat lazily on the top of mountains as his words flooded river banks, and his qi could hold a million soldiers back. Someone once moved mountains and shifted hills with just one brush, his paintings so captivating it could enchant immortals and deities.

That year, the warmth of spring made the flowers bloom. They were merely an ordinary butcher, a bookworm, a chicken farmer and a poor artist. This is the story of how a Low Level Martial World Continent was transformed into the Ultimate Fantasy Universe.
