"Disciples pay respects to Master!"
In the ancient palace, Qin Feng and Liu Xuanling stood below, bowing respectfully to Ning Wuxu!
In the Cultivation World, hierarchy is of great importance. It is not determined by cultivation, just like a son cannot suddenly become a father. If hierarchy and ethics are disrupted, it would cause chaos in the entire Cultivation World, even more chaotic than many Demon Path worlds.
Therefore, even though Qin Feng and Liu Xuanling have proven their Dao and attained immortality, becoming true powers in the Cultivation World, they still show great respect to their master, not daring to disrupt the rules.
Of course, this is towards their own master. If it were other elders who were merely higher in hierarchy but actually far inferior in cultivation, they would not hold the same status.
