Based on my observations over the years, I've reached a conclusion.
Even if the level of magic techniques is high and powerful, the retention effect won't be ideal if the tier of the Spirit Field doesn't reach a sufficient level.
When the same kind of Tier Three Spirit Medicines are planted in a Tier Two Top Grade and Tier Three Lower Grade Spirit Field, and the same Spirit Farmer cultivates them, there's a noticeable difference in the growth speed of the medicine age.
Cultivators in the Western Continent do not occupy high-grade spirit veins, so the upper limit of each power is capped at the Golden Core level, or even lower.
Take the Golden Spirit Sect as an example, Sunrise Peak has numerous spirit vein nodes, theoretically enough to sustain the cultivation needs of multiple cultivators.
However, to satisfy the cultivation of two Golden Core Ancestors, the spiritual qi at many spirit vein nodes is drawn away by arrays, gathering in the Ancestor's grotto mansion.
