In Soul Emperor, Xiao Du divides the cultivation ranks into three major realms. The first is the Innate Realm, classified by the colors of the rainbow in order: red, orange, yellow, green, cyan, blue, and violet. Each rank is further divided into early, middle, and late stages. The second is the Venerable Realm, classified by black, white, and gold in order: Black Rank (Human Venerable), White Rank (Earth Venerable), and Gold Rank (Heavenly Venerable). Each rank is also divided into early, middle, and late stages. The third is the Divine Path Realm, comprising Human God, Earth God, and Heaven God. Human God corresponds to the Domain, Earth God to the Territory, and Heaven God to the True Realm. Spirit Beast rank classifications: In Soul Emperor, Xiao Du divides spirit beasts into four major ranks. The first is the wild beast, an ordinary animal with no intelligence. The second is the spirit beast, ranks one through seven. These beasts have awakened intelligence, though it is not fully developed. Only upon reaching rank seven can a spirit beast form a beast core and speak. The third is the sacred beast, ranks eight through ten. Heaven and earth will send down tribulations to temper these beasts, which can also wield the power of heaven and earth for their own use. The fourth is the divine beast, ranks one through three: a first-rank divine beast has a Domain, a second-rank divine beast has a Territory, and a third-rank divine beast has a True Realm.
