There are 5 major stages in Pre-Celestial Cultivation.
Qi Condenstation
Absorbing and refining the spiritual energy and redirecting it to the body. Then guiding the flow to reach the lower dantian area. By doing this, the body will adjust on the presence of spiritual energy and will form a cultivation base that stores spiritual energy.
Foundation Establishment
Guiding the spiritual energy to circulate throughout the body. By doing this, the skin, muscles, bone, blood, and organs will constantly be nourished. By the end of this stage, the cultivator will now be different from mortals akin to having a rebirth of the body. They will possess greater strength than the bodies of mortals.
Core Formation
Involves forming a gold core by using the dantian as a crucible and the cultivation base as a raw material. The gold core is a sphere of dense spiritual energy. Cultivators at this stage will experience a sudden growth of strength and their control of spiritual energy will increase. They will also be able to lift their body and fly in the sky.
Nascent soul Formation
Involves transforming the gold core and making it a Nascent soul. This Nascent soul is the cultivator's accumulated cultivation. Legends say that when the body of a Nascent soul dies, his soul can escape and find another suitable dying body. They will slowly adapt and change the body through years of refining. The body will slowly transform and be changed to the appearance of their old body. However, unique constitutions cannot be changed nor transferred.
Soul Formation
Each cultivator can form a 'domain' using their soul. This domain will appear in a limited time. In the presence of this domain, the user will experience a quick growth of strength. Some domains can also affect other cultivators align with their nature. Each cultivator can only learn one domain, and will be permanently marked to their soul.
