Breaks Lung's ribs

I let out a wordless scream, and with a feat of agility that would have made professional gymnasts green with envy, I swung my torso up, curled my knees against my stomach, and planted both of my feet in his chest with all of my strength.

Snap-snap-snap, went his ribs, barely healed from my previous punches. Lung gave what might generously be called a startled yelp and reflexively let me go to cradle his injury again as the force shoved him back several feet. I’d only just landed back on the ground before he’d uncurled himself and turned a blazing glare my way.
