The college restricted the use of force and forbid any killings. There were a few rules that couldn't be violated. If anyone did, they would be executed no matter who it was. With such a huge college, it could easily contain several thousand cadets. Among these thousands of cadets, there were individuals that had the wealthy status, and there were the commoner prodigies. It was inevitable to avoid any conflicts with so many different personalities around, and this was why the Battle Arena existed.
The Battle Arena—also located at the South Courtyard—was a place that was meant for fights. As long as both parties signed the life-and-death form, the fight could even decide one's life and death. Even if one of the combatants was beaten into a cripple, the college would still ignore it.
