The advancement in cultivation for an Incense Fire Deity was simple and crude, requiring only a sufficient number of followers; there was no need for the arduous practice that ordinary cultivators undergo.
As the number of followers increased, the cultivation of Chu Zheng's Incense Fire Divine Path expanded rapidly.
The Incense Fire Divine Path begins with the Divine Embryo and gives birth to the Soul. When the Soul transforms into a spirit, it enters the realm of the Spirit Lord.
Spirit Lords are ranked as Lower Rank, Middle Rank, and Upper Rank, corresponding to the Soul Condensing, Divine Infant, and Divine Transformation of the Immortal Path, covering Third Order through Fifth Order.
Higher up is the Heavenly Monarch, divided into lower and upper ranks: the Junior Heavenly Monarch is comparable to an Immortal Path cultivator in the Tongxuan Secret Realm, while the Upper Heavenly Monarch could be paralleled with the Immortal Tribulation.
