Wang Wei looked at the 90 zhang tower for a while with awe, then he entered without hesitation. The Battle Tower was one of the few places in the sect that did not require contribution points.
This rule was set in order to encourage disciples to train and hone their fighting skills. As the tower is divided into different difficulties, disciples are in fact rewarded with a certain amount of contribution points for passing a certain level.
After entering the tower, Wang Wei found himself alone in a separate space in a fighting arena, and there was someone else waiting for him. He could tell that this person had the same 9th Layer of Body Refining Realm as him.
He also knew that this person--who looked exactly like a person--was in fact a construct similar to puppets created by the Battle Tower.
