Cunkuu was not surprised by the way his attack was avoided. The adversary he had tried to strike down turned out to either be far less experienced, and skilled, than expected or was holding back. Both were incredibly offensive to the young man. If the case was the first, that would mean a weakling was looking down on him. If the case was the second, that would mean the singed one was either underestimating him or was trying to make himself appear weak, so that Cunkuu would let his guard down. If he was being underestimated, the young man concluded he would feel even more offended, as that meant he appeared less powerful than he truly was. If he was being deceived, he was not going to allow some disturbed man, who was unwilling to share knowledge, get the better of him. 

"Neither needs to die, but then again those monks are all dead, but you live!" Retorted Cunkuu and repeated his action. Opening his palm and casting the spell. If he was allowed to finish, the fireball would fly at the exactly same velocity and in the same direction sa the previous one.
