Master Li's combat class had two types.
One was sparring between students, which he oversaw. This type of combat class was directly linked to academic credits; winners gained points while losers had points deducted.
For the beasts of the Lizi Class, credits were as precious as their dog lives, and nothing like fairness, justice, or transparency existed here. They picked on the weaker ones, beating them down and continuing to do so until they had stripped you of all your points.
Of course, this was only against students from other classes. The Lizi Class would never do such a thing to their own members.
Because that method was still considered too weak, too easily countered by other people in the Lizi Class. So, if they drew one of their own as an opponent, they would often prepare in advance. For example, sending explicit images to the opponent right before battle, slipping laxatives into their food, or throwing a sack over their head and clubbing them.
Does this seem too harsh?
