I hadn't expected that the classes would be so hands-on. But it was a better option than being purely theoretical.
Thanks to my mother, I also had a good foundation in the knowledge of arrays. So, guessing the possible arrays used in the folding fan of instructor Luo Chen wasn't an issue.
I could even form many alternatives for the suitable array combination, the count further increasing for each change in the combination of the runes in each individual array.
The only issue was the composition of the overall formation.
Similar to the Alpha, Beta, Gamma and the ever-cryptic Omega runes used to create an array, a single formation constitutes many arrays.
Thus, for the creation of a formation that results in the 'Azures soaring High', it was not just simply to deduce the arrays used in the formation. But the crux of the creation lay with how the arrays were arranged within and connected to each other to draw the complete formation.
