In a sea of clouds far from Earth lies a white planet called Yunhai. Yunhai consists of four continents, and the locals divide them into the East, South, West, and North. Mu Yun transmigrates to Xin Jia Town in the southern continent, his new home. There are no countries here, either. The basic administrative units are villages and towns, while the governing body is the Union. Each continent has its own Union, and Yunhai's Union is made up of the unions from all four continents. All around Yunhai stretches an endless ocean, which the locals call the Yunhai Sea.
This is a parallel world to Earth. One stormy night, a mercenary is struck by lightning, and his soul ascends to Yunhai. Mu Yun builds a guild, trains his inner power, improves his cultivation, and becomes the next king of Yunhai. He claims secret manuals, helps the good, and champions justice, forging a legend in Yunhai. Heroes surround him, mercenaries gather at his side, and his ambitions never waver. Unexpected events keep coming, and the tangled affairs of the world are impossible to unravel...
