Although the various schools didn't have any fixed requirements about a famous school's headmaster, their cultivation base mustn't be too weak, and their star level couldn't be too low either. Otherwise, how were they going to convince people?
If they didn't at least have 15 great teacher halos, it'd be too embarrassing.
A disciplining halo like the Teacher for a Day, Father for Life could be said to be basic.
Which headmaster would beat others up when they flew into a rage? That'd be too low class. Instead, all of them would send out halos when they flared up, getting the students or teachers to drop to their knees in submission!
When these headmasters heard Sun Mo retorting, they knew that things would go bad for him. Headmaster Wei would be able to crush Sun Mo just by using a great teacher halo.
(You have a reason? You want to retort? I'm sorry, you won't be able to even open your mouth!)
