Noticing that her Sensei had increased the pace, Boa prepared herself for the next techniques.
Quickly as instructed, Boa inhales deeply as she channels her Katon chakra into her lungs. In a quick motion, she exhales by releasing the chakra accumulated, and thereby releasing it in the form of a large number of fireballs. These fireballs cover a large area, so that the dummy won't be able to dodge her attack. Once she completes it, she turns towards the next dummy to perform the next technique.
In a swift motion, Boa takes out 5 shurikens in each of her hands and spreads it. With a simply swing, she throws all 10 of them at the dummies after channeling her katon chakra into them. As the shuriken reach closer to the opponents, She ignites them with her mental command, and thereby causing more damage.
