"Bring the chakra out as a thin film over the front of your fist, and remember to send it along the sides of your wrist to minimize the recoil from shattering your bones," Tsunade intoned on the disciplines of the chakra-enforced martial arts. "You need the speed to be second nature, quick jab and release the chakra over a small area. It will have the greatest impact."

"Shishou like this?" Sakura asked while bringing a thick field of chakra to her hand practicing the feel of the technique. "Try it out" Tsunade smirked, "look there is a boulder over there. Crack it." It kind of reminded her of Kakashi's head. His stupid head that was three hours late for their meeting. His stupid spiky haired face that sprung Gai-sensei on her when she was trying to come off an emergency abdominal exploration for a stupid civilian boy that went joy riding into a vegetable cart. Stupid stand, stupid sensei, stupid sensei's hair, stupid no sleep and going into 34 hours of being unbelievably awake to crack boulders.

"SHANARO!" Crack it snapped clean, it definitely broke. "And that is why you remember to fortify your wrist when using the chakra release method," Tsunade hummed hand glowing green as her student tried to stifle her scream into her pursed lips. Hands were not supposed to look like that.
