"Item Modification"
In short, students were super powerful here and if the special instructors were not capable, they would be 'beaten to death'.
On the contrary, the capable instructors would gain the students' respect, fear and awe, which would surely build their foundation to stay in the academy for a long time.
The balance check between students and instructors was there so that instructors would not suppress students behind the academy's back and students were encouraged to always challenge the strong.
This tradition and system did cultivate many leaders among the students who weren't afraid to go against the instructors, but there were some evil students who liked to vent their stress to weaker instructors.
This academy was more and more like a mini society mimicking the situation of the outside world.
Since it was not allowed to bring anything aside from the clothes worn on the body, it would be meaningless to prepare anything for this test.
