Regarding pill medicines related to dantian magical power, the main focus is on supplementing spiritual qi, enhancing refinement, and promoting the spirit root's affinity to heaven and earth spiritual qi. The principles are very lucid, and the cultivator's body's meridians and flesh are easily discerned. As long as the alchemy inheritance is comprehended thoroughly and the condensed pill fire is skillfully controlled, it's relatively easy.
However, for medicines related to the divine soul, because the sea of consciousness of the human race cultivators is the celestial secret vault, even a true man cannot discern it directly and can only rely on experience and insight. This makes the refinement difficulty of divine soul-type pill medicines very high.
