Cultivation has many levels, and as an individual progresses in their cultivation they gain access to higher realms of existence.
The mortal realm is also known as the Physical Realm. Progression through the mortal realm involves absorbing greater amounts of spiritual energy (Qi) into the body. As an individual's spiritual energy increases it becomes denser and changes form. Their cultivation "deepens" upon a successful change in form. Changes in form are incredibly difficult and often require assistance from medicines, tools, or spiritual pills.
|1||Qi Condensation (炼气)||100 years||The starting stage of cultivation. Those in this stage cannot be called cultivators, but merely practitioners. The lifespan of Individuals does not change, and are considered enhanced mortals. The mortal body starts to absorb natural energy from the world and gather spiritual energy (Qi) inside the body. To progress, an individual must collect and condense more spiritual energy. In this stage, the spiritual energy is visually depicted as forming clouds. As time goes on, this stage varies in length and power.|
|2||Foundation Establishment (筑基)||200 years||Upon successfully collecting and condensing spiritual energy into a liquid, an individual enters the Foundation Establishment stage of cultivation. At this stage, individuals have greater power that further enhances their magic abilities.|
|300 ~ 600 years||An individual enters the Core Formation stage when they collect and further condense their spiritual energy into a solid "core" - often depicted as an Orb. At this stage individuals increase the lifespan of their mortal bodies by hundreds of years, and have greater power that dwarfs Late Foundation Establishment cultivators.|
|800 ~ 2,000 years||Once a "core" has reached sufficient density, it can be forcefully collapsed and molded to form a "Nascent Soul". A cultivator reaches the Nascent Soul stage upon successful formation of a Nascent Soul. Under rare circumstances, an individual may form more than one Nascent Soul. Progression through the Nascent Soul stage involves absorbing spiritual energy to refine the Nascent Soul.|
|2,000 ~ 5,000 years||The fifth stage of cultivation. The Nascent Soul has reached its pinnacle, and can no longer progress. Thus, the Nascent Soul will then begin to interact with the higher energies of Heaven and Earth. A chance of death is present as a tribulation occurs to enter this stage. Should the Nascent Soul succeed in becoming half immortal soul, one will have the power to manipulate the energies of the world to fight, or cut open space to travel a thousand miles in one leap or instantly approach the enemy. Can be called first-rate or powerhouse in second-rate sects, and first-rate expert in first-rate sects or factions.|
|Unlimited lifespan (but usually die due to heavenly tribulation)||The sixth and final stage of cultivation before attempting to truly become a Immortal. The Nascent Soul has reached a point of no return in terms of power, and is only a small part away from becoming a immortal soul, however, the power of the void or space has not been infused, and many pieces of one's mortal shackles are still in place. In this stage, only a piece of emotion should be kept, and the Nascent Soul shall eventually become a immortal soul. There is a high chance of death if attempting to enter this stage. Can be seen as the pinnacle figures of the Spirit Realm.
|Heaven's Tribulation||Instant death or continued life.||Intermission between Void Refinement and Integration/Synthesis. One will either die or succeed.|
|Unlimited lifespan (but usually die due to heavenly tribulation)||At this stage, one has officially stepped beyond the mortal world, and can travel into boundless space with no issues. At this stage, one will no longer use heaven and earth energy, but natural essence energy, far superior and more powerful. At this level, the immortal soul is true in strength and form, and one has officially gained one piece of immortality. A tribulation will accompany every breakthrough. This is considered to be the highest stage of cultivation in the Spirit Realm. The Three Human Sovereigns are at this level.|
|3||Grand Ascension / Mahayana
|A realm equal to a Demon Ancestor in the demon race. It is incredibly scarce in the Spirit Realm, much less in the lower mortal world. 99% of cultivators will die before entering this stage. However, entering this stage will not grant access to the Immortal World. Those that achieved this stage are often stuck in the Spirit Realm as becoming a True Immortal is too hard.|
|Unlimited lifespan (but usually die due to heavenly tribulation)||After passing the Tribulation you can ascend to the Immortal World|
|Unlimited lifespan (but usually die due to Tribulation of Three Declines)||The last and final realm in the mortal spiritual world, also the beginning of the Immortal World. Not much is known besides that this stage can directly flip over a mortal spiritual world. It has been shown that the demon race fear this level to their bones. The presence of a True Immortal is enough to send the demon race into a frenzy just from the thought of one.|
|Unlimited lifespan (but usually die due to Tribulation of Five Declines)|
|3||Supreme Unity Jade Immortal||Unlimited lifespan|
|1000 ~ 5000 years||A realm that exists once someone fails to become a True Immortal. This is the realm one enters should they somehow survive their failed tribulation. Their lifespan is decreased enormously, however, their power is nonetheless able to dominate all under the True Immortal level. There is little hope for those in this level. In the spiritual world, a Loose Immortal will commonly go on a rampage once their life is coming to an end, causing damage to all around them. However, it is possible to have minor breakthroughs in this realm. There are also differences in the strengths of Loose Immortals. This realm is not mentioned much in the novel itself, if not at all. The stage is mostly implied.|
