When great teachers wanted to climb up in ranks, they needed to increase their number of halo. This was a condition that must be met because the halos were a very substantial aspect of educating others.
Speaking of which, high-grade halos like Retentive Memory, Enlightenment Provision, Meticulous Discussion, or even the more commonly seen Encyclopedic Knowledge and Complete Focus were tools that could greatly improve the student's learning efficiency.
The higher the star rank of a great teacher, the more halos they would possess. In that case, it also meant that their value would be higher.
Just like now when Yan Ju had casually cast Profound Words and berated Sun Mo.
Did he need to consider Sun Mo's reputation and thoughts?
Nope!
From his point of view, he was just teaching an ignorant junior a lesson.
Even if Sun Mo was unhappy, Sun Mo wouldn't be able to bite him.
