For immortals, Mortal Immortals, Earth Immortals, and Celestial Immortals represent merely the beginning of the path to immortality, categorized as low-tier immortal beings.
Zhou Chuan had realized long ago that the immortal cultivation system bore a striking resemblance to the human cultivator system. A Mortal Immortal was much like the Qi Condensation stage, gathering Qi and practicing it; an Earth Immortal corresponded to the Foundation Establishment stage, where one condensed and refined the Divine Soul; and a Celestial Immortal was akin to the Core Formation stage, sensing the power of heaven and earth while gaining a preliminary glimpse into the origin of the laws.
The difference was that immortals faced far more bottlenecks than mortal cultivators, and the suppression by the Heavenly Dao was much harsher. This was especially true when it came to comprehending the Dao and the laws of the Heavenly Dao—one had to learn how to be a proper person before learning how to cultivate. Without successful comprehension of the Dao, advancing one's Cultivation base by even an inch was out of the question. Every immortal cultivator had to abide by the laws of nature and the laws of time.
