After the time for the class had arrived, a middle-aged man at the Refining Void Realm walked in slowly, clad in a grey Taoist robe. Within the Tai Xuan Dao Palace, there was no set attire for disciples, and one could wear whatever they liked.
Similarly, there wasn't a strict distinction between teachers and students. As long as one had the capability in a certain area to teach disciples of lower realms, they could accept the Dao Palace's examination. Once they passed, they would be able to offer classes and teach disciples within a certain realm.
For disciples to participate in classes, they needed to pay with achievement points. The Hall of Preaching would distribute a certain proportion of these points as teaching rewards to the cultivators who offered classes.
