After this failed attempt Giovanni begins to feel discouraged and angry at himself for making stupid mistakes. Instead of feeling bad about it he takes a deep breath and assumes the standard Jyuuken stance being somewhat turned to the right with his left leg forward having most of his weight on it and his left hand leading with the right one slightly behind and above. Both hands are set up in a relaxed and lean manner. Giovanni then begins his new assault on the clone. He extended his right arm which was at a higher position than his left. Extending his arm he delivered a gentle push with his palm to the clones stomach damaging the soft tissue, and the burst of chakra knocking his breath out. This causing the clone to double over due to the pain. Using this, Giovanni pulls his left hand back and slamming it down from above onto the clones nape releasing a burst of chakra upon contact. The chakra would cause choking as well as muscle restraction making it troublesome to breathe properly. Sending his right arm lower, beneath the clone, Giovanni upper cuts him with a push and a burst of chakra, making him stand up straight again. With the strike aimed below the chin, the chakra would affect his tounge numbing his entire mouth and damaging the lower jaw, possibly dislocating it. For the fourth strike Giovanni thrusts his left arm forwards aiming for he clones heart releasing a burst of chakra causing increased heart rate and maybe even heart damage. Immediately after that Giovanni thrusts his right arm to the clones left shoulder numbing that part while at the same time turning the clone counterclockwise so his back is facing Giovanni. For the final strike Giovanni thrusts both his arms forwards releasing a burst of chakra into the clones back damaging the nerves in his spine with his chakra and causing the clone to fall to the ground.Couple of problems.
1: If you're attacking the abdomen, you're not hitting the stomach. The stomach is a little bit up more and to the left, kind of sitting just at the base of the rib cage. The area you struck would be the intestines.
2: Right chest area isn't going to his the diaphragm, you would just be hitting the lung. The diaphragm arc across your body just below your pecs. Its more of the mid-torso than chest area.
Do it again. And this time add 2 more strikes to the back of the clone.
