The space in all directions is called the universe; all time, past and present, is called the ages.
The size of the "universe" cannot be measured by mortal eyes, and the length of the "ages" cannot be traced through historical records. Yet some people, following the ancient methods left behind by their predecessors, devote themselves to cultivation over long periods and master abilities beyond the wildest belief of ordinary people. They fly through the skies and burrow through the earth, soaring through the air. The most powerful can move mountains, fill seas, summon rain, and command the wind. Step by step, they defy the heavens, until they hold power over life and death and uncover the mysteries of heaven and earth.
