In this realm, the existence of seven distinct grades of potential in martial arts was widely acknowledged. These grades, known as Common, Human, Earth, Heaven, Saint, Emperor, and Hollow Lord, served as a measure of an individual's innate capacity for mastery in the martial arts.
Furthermore, the path of martial arts was intricately structured, consisting of ten levels known as the Dan steps. Each step represented a milestone in a martial artist's journey, signifying a deepened understanding of the martial world.

Within this framework, it was firmly believed that individuals with Common or Human grade potential could never surpass the Shõ Dan step. Although the extent of their attainments at this level might vary, they were forever bound within its confines.
