Even though three months in the Subterranean Gallery couldn't be considered to be a severe punishment, it couldn't be said to be a light one either.
The Subterranean Gallery was the intersection point between the Master Teacher Continent and the otherworldly battlefields. As such, it was constantly plagued with overwhelming killing intent. From time to time, Otherworldly Demons might even appear. Without a doubt, it was one of the most dangerous lands on the Master Teacher Continent, and most of those who ventured into its depths never returned alive.
Only master teachers who had committed unpardonable crimes or wanted to make one last contribution to mankind would apply to enter those lands.
This was also the same with School Head Lu Feng back then.
