Those who were still casting the Flame Ball were a little perplexed with Xiao Lin's guidance. The spellcasting movements and chants that they learnt were the standard ones that they learnt in class, but truthfully speaking, there was no absolute criterion for spellcasting movements. The key was gathering the elements up and recombining them using the established order.
The process of achieving that goal was endless and varied, but the academy was worried that the students might deviate from the right way. After all, many bad habits were difficult to change once firmly entrenched into a beginner, which was why the academy had always taught the most standard moves to the students only.
In fact, Xiao Lin did not have much experience in that and could only give some guidance to the freshmen who used the Flame Ball. He never once talked about any other spells for fear that his guidance was erroneous.
