Ok, got it bro.
This is a whole new experience for Suzaku, finally learning how to use his ability, the joy bursting through him was so much that he couldn't contain it, so once his sensei told him to begin, he started by building up his fire chakra at the same time his wind chakra. It was easy for him since he has mastered both the two elements and then with great and immense concentration, he merges the two chakra natures together and releases it immediately. He then amasses the scorch chakra quickly and with knowledge he has acquired from learning the elements, he was able to create a beautiful scorch wall right in front of himself. That was easy since he just had to let it go, now he had to shape it for the second technique so without wasting time, he immediately goes through the process once again but this time instead of just releasing, he uses his fore knowledge to shape manipulate the scorch chakra into an orb before letting it materialize into a single small scorch orb that he launches at the tree instantly.
