"Good, now repeat that process till the water ball on your hand disappears completely. And don't lose your focus."
"Hmm…." replied Aryan and kept on doing the same step again and again, till the water ball disappears from his hand and a small ring of tornado forms around his index finger made up of oxygen gas only.
"You are doing good," complemented Aditya again and asked him to increase the fireball size on his right hand by adding more energy and forcibly compress its size. Since it was an easy task for him, he increased the size to that of a football, by adding more energy, then compressed it by wrapping it in a layer of his mental energy.
He was getting a rough idea, that when that fireball hits the target it will give a big explosion, but he couldn't understand what's the work of those oxygen revolving on his left hand's index finger.
"Now wrap those oxygen gas around the fireball and let it mix with it for some time," instructed Aditya.
