Soryen slapped his cheeks with both of his hands at the same time ,he tried to psyche himself up for the last try, this would pretty much leave him standing with just a smidge of chakra left.

The boy closed his eyes and once again performed the tiger seal, this time he aimed to release the fires at a faster rate but with the same chakra at hand. Just  as he started to brew up the katon chakra inside his gut he inhaled a good amount of compressed air. He let it sit in his lungs and cheeks for a brief moment until he released the charka in his stomach to fly up to his lungs and then directly through his mouth.

Soryen's eyes opened up and widened as he squatted slightly and leaned forward, he was aiming to get all the air he managed to suck up  out of his lungs  ,leaving him without breath in the end.
The boy opened his mouth slightly and quickly let out the same flame as he did a few minutes ago, not much progress was seen beside the fact that he managed to conjure it up at a faster rate.He began puffing and huffing as he sat down to take a break, he was beat. This much ninjutsu training in one day, that wasn't what this young lad was used to.

"Ahh..man...." he muttered.
