After leaving the fourth floor, Nick went to the fifth floor, the floor that held all the Specters used to train new Extractors.
One of the new Early Adolescents was very useful for training.
Although, it wasn't for Newbies, and it also wasn't necessarily for increasing an Extractor's level.
After reaching the fifth floor, Nick went to one of the eastern Containment Units.
He put his hand on the door and waited for a moment.
BANG! BANG!
Nick rapidly opened the door, entered, and quickly closed it.
BANG!
Then, Nick stepped to the side as a bloodred shadow shot past him, hitting the entrance.
Nick had expected that to happen, and he wasn't worried.
The red Specter immediately attacked Nick again, but Nick just quickly sidestepped.
It wasn't very difficult to avoid an Early Adolescent.
