Domain Level (境界) [Jing Jie] –
Martial cultivation is separated into a series of important stages of practise, and those important stages are referred to as domain levels.
In the Mortal Realm, Xiuzhen Practitioners will usually experience the following order of domain levels: Houtian stage, Xiantian stage, Jindan stage, Yuanying stage, Dongxu stage, Kongming stage, Dujie stage, and Dacheng stage. On attaining Dacheng stage, after a period of time, the Xiuzhen Practitioner will Ascend into the Ascendant Realms.
Xiuzhen Practitioners who have their physical bodies destroyed and scattered into pieces during their Six of Nine Heavenly Tribulations or Nine of Nine Heavenly Tribulations are known as Loose Practitioners and have to experience a total of Twelve Heavenly Tribulations. After a typical Loose Practitioner completes his or her Twelfth Heavenly Tribulation, he or she will Ascend to the Ascendant Realms and begin practising as either a Devil King, Demon King, or Golden Immortal, depending on his or her method of martial cultivation.
In the Ascendant Realms, Xiuzhen Practitioners will usually experience three domain levels, but each domain level consists of nine tiers. Each tier of practise increases the martial capabilities of the Xiuzhen Practitioner by a significant level.
For Xiumo Practitioners, they will experience the following order of domain levels: Heavenly Devil, Devil King, Devil Emperor.
For Xiuyao Practitioners, they will experience the following order of domain levels: Heavenly Demon, Demon King, Demon Emperor.
For Xiuxian Practitioners, they will experience the following order of domain levels: Heavenly Immortal, Golden Immortal, Mystic Immortal.
A practitioner of the Stellar Transformations do not follow the same stages of practise as typical Xiuzhen Practitioners.
In the Mortal Realm, the stages of domain levels for the Stellar Transformations are in the order as follows: Nebula stage, Meteor stage, Stellar Core stage, Planet stage, Dujie stage, and the Stellar stage.
