Among the nine sects, it is said that there was a person who could be punished regardless of the reason, from the head of the family to the slaves.
This person calls it - fairy eye.
Legend has it that the Immortal Eye devotes the efforts of the nine sects to support it, and it changes every hundred years. One theory is that the Immortal Eye of the previous generation left a will and was selected among the nine sects. Another theory is that the head of the nine sects was chosen by lot.
Anyone who attains the Immortal Eye will be alone for the rest of his life, and cannot leave Fengxian Tower without the company of any head of the Nine Sects. But in exchange, the next generation of nine sect heirs after the Immortal Eye are all sons. Therefore, there are rules among the nine sects. Anyone who becomes the Immortal Eye is called "Father" for men and "Amu" for women.
