A spirit testing artifact that has stood since the Wuxiang Sect's founding. When a person places their hand on it, spiritual energy climbs up markings to indicate talent level. The vast majority have no Spirit Root, less than one percent have Spirit Veins, and very few exceed the seventh segment. Those at the ninth segment become grand masters of the age. Lu Wujiu shattered this stone during his Spirit Testing because his talent exceeded its measuring capacity.
