Ever since the reconstruction and the merging of the Netherworld with Qing Xuan Earth and Star to form the two realms of the Yin and Yang, the Qing Xuan Earth and Star had expanded significantly and was known as the mortal realm by the holy deities. Besides the Daluo immortals, no one knew how big the mortal realm was.
Within the world, there were four extensive continents known as the Yuan Continent, Xuan Continent, Ling Continent and the Tian Continent. Beyond the continents, there were countless schools of cultivation, a big population of living creatures and the demons as well as celestial beings that acted out the joys of sorrows of the world.
As time ran its course, the chaos in the mortal realm had been resolved. For the mortals who lived a short period of time, the dramatic change of the world millions of years ago were just a heap of old books.
