During the meal, Li Dahai asked Li Anran, "Brother Anran, what are the definitive milestones for reaching the Six-Star and Seven-Star levels?"
Li Anran thought for a moment and replied, "The Immortal Mountain lights a life-lamp for every Six-Star disciple. Therefore, any disciple who believes they have reached the Six-Star level must undergo an assessment by the Immortal Mountain. According to the evaluation standards of the Immortal Mountain, it requires clearing the twelve regular meridians and seven of the eight extraordinary meridians. There is no specific restriction on which seven meridians must be cleared."
Using the clearing of meridians as the standard for determining star ranks was not only the method used by the Zhudi Mountain Sect; most other Immortal Mountains adopted the exact same approach.
