The title of a teacher is given based on the quality of their teaching and the seriousness of the students, granting varying rewards of experience.
However, the number of students will not significantly impact the reward, otherwise, one could simply boost their experience by increasing the number of students they teach.
Currently, the title of "Junior Teacher" has reached its full extent at the third level, with the monthly Master's Day still ongoing, although the cultivation level of the gratitude has increased.
However, the cultivation level he can obtain from the students remains quite small.
The gap between the Golden Core Realm and Qi Refining Realm is as wide as that between an adult and an ant. To a Golden Core Real Person, a thousand Qi Refining disciples combined aren't much of a challenge.
