Despite his obvious desire to test himself at the Sword Tempering Cave, Cedric held himself back.
He has already seen everything he needs to see at the dojo, and his position as a student of the Sword Path Class was also established firmly. He could've gone to the cave as soon as the next day came but he didn't.
Cedric knew that he'd be distracted by it. Actually, he's nearly certain that he would be immersed in it. He still has other classes to attend and he cannot miss them so he set it aside for now.
Currently, he's gone to another room within the Combat Specialization Tower to attend 'Elements 101' Class since it's Monday today. He didn't want to miss it since it was his first class and first impression matters.
When he got into the 'classroom', Cedric discovered a theme somehow. Like what he experienced in his previous class, the 'classroom' for this class turns out to be unique as well.
