The protagonist is in a vast world of cultivation, filled with thousands of races, full of dangers but full of opportunities - the Nine Heavens Mysterious Domain. The entire world is divided into the Eastern Region (relics of prehistoric times, many ancient alien species and secret realms), the Western Region (the quicksand sea, exotic customs, many strange creatures and elemental powers), the Southern Region (miasma rainforest, where poisons and vitality coexist), the Northern Region (frozen snowy regions, ancient ice fields, descendants of mythical beasts), and the Central Region (the core of civilization, dynasties competing for hegemony, and numerous sects). Deep in the Nine Heavens Mysterious Territory, it is said that there is a broken passage or secret realm that connects the ancient times.
