Actually, it's not overly complicated. Mana, to put it simply, is the power of rules. When one cultivates to a certain extent, natural phenomena will occur. This is, in essence, a reflection of powerful mana.
The Core Formation Stage is divided into three phases: early, middle, and late, with distinct transformations occurring in each.
Thus, forming a Golden Core is not an end but merely the beginning.
Each phase may require hundreds of years of effort, along with an enormous expenditure of manpower and resources.
Many cultivators who reach this stage have already hit their ceiling—either their potential is depleted, or their foundations are too shallow.
Some cultivators at the stage of Qi Refinement and Divine Establishment absorbed Heaven and Earth Essence Qi of poor quality, leaving them virtually no room for advancement at this level.
This is why high-quality True Qi in earlier stages is necessary.
The higher the grade early on, the greater the potential ceiling later.
