How were the levels of cultivation and sainthood that were often used in novels divided? Starting from Qi Refinement

In the novels, the cultivation levels were usually divided according to the difficulty of cultivation and the level of strength. Qi Cultivation, Foundation Establishment, Core Formation, Nascent Soul, Soul Formation, Body Integration, Transcendent, and Ascension were the common cultivation realms. These realms usually corresponded to the improvement of a cultivator's strength and the results of their cultivation. When dividing the ranks, the strength of cultivators would generally be divided into the following levels: 1. Mortal Realm: Cultivators can only use the spiritual energy in their bodies for simple cultivation during the initial stage of cultivation. 2. Foundation Establishment Realm: Cultivators gradually increase their basic cultivation strength by condensing the spiritual energy in their bodies into spiritual sense and spiritual power through hard cultivation. 3. Core Formation Realm: Cultivators can further increase their strength by condensing their spiritual sense and spiritual power into a Dan Dan that contains spiritual energy through longer periods of cultivation. 4. Nascent Soul Realm: Cultivators absorb the spiritual energy in the pill to form a Nascent Soul. When their strength reaches its peak, they can use the power of the Nascent Soul to cultivate and fight. 5. Incarnation Realm: Cultivators can use the power of the Nascent Soul to reach the Incarnation Realm and control themselves to transform into a god with extremely high combat power. 6. Body Integration Realm: Cultivators divide their bodies into multiple parts through long-term cultivation and finally reach the Body Integration Realm. They can condense their strength into one and be extremely powerful. Spirit Realm: After a cultivator reaches the Body Integration Realm, their strength will further increase. They will be able to surpass ordinary people's understanding and possess extraordinary wisdom and insight. 8. Soaring Realm: Cultivators can reach the Soaring Realm through mysterious means, allowing them to cross the restrictions of the region and enter the wider world of cultivation. It was important to note that these realms were not fixed. There might be different settings and explanations in different novels. At the same time, these realms were just a kind of imagination and expression of the author's creation. They did not represent the physical laws of the real world.
