There are good gods and evil gods who follow the rules, and there are evil gods who don't follow the rules. When a time traveler collides with rules he doesn't agree with, the story of the evil god begins... This is the story of a good man who traveled through time and became a giant jellyfish, searching for something in the world of swords and magic, and ultimately changed the world.

Three emperors died one after another, and the prince who had never been noticed succeeded to the throne inexplicably and was in many dangers. The Queen Mother didn't like him, and always wanted to create a new emperor who was younger and more obedient; his half-brothers didn't like him, thinking that he had taken away the throne that belonged to them; the eunuchs and maids also didn't like him, thinking that he didn't look like a real emperor... The Ruzi Emperor had no choice but to save himself.
