In the Nine Provinces continent, there is a saying: without opening their apertures, spirits cannot take human form, and without opening their apertures, humans cannot cultivate.
To embark on the path of cultivation, one must open the Spirit Apertures. Only by doing so does one become qualified to cultivate.
Opening Spirit Apertures is no simple task. Among ordinary people who undergo systematic training, only about one percent manage to open their apertures. For those born into cultivation families or sects, guided by elders, this ratio might be slightly higher.
