A week was short, especially if you wanted to carry out a complicated task. In the case of Cecilia, Claire, Revna, and Sasha's training, that week felt like an eternity. Under the hellish training regimen carried out under the hands of Xiauyue and Fei Long, the girls' strength underwent a metamorphosis regarding combat prowess.
Taking Claire as an example. The emerald green-eyed girl had trained under Xiauyue's guidance. She made significant progress in developing her own fighting style, learning to combine her Arcana with tactics and maneuvers that made her a force to be reckoned with.
For Cecilia, the week could be described as a never-ending fight. Mei Fei Long was quite direct with how she trained the former priestess. For seven days, Fei Long had taken Cecilia to the training ground and attacked her non-stop for hours.
