Normally the human body only uses 20% of it's chakra in order to prevent the body from harming itself through over-exertion. However: you are different.
You have learned the Eight Gates technique, allowing you to remove your bodies natural limiters (or gates) for greater power through. The gates are as follows: Gate of Opening -Removes Mental inhibitions Gate of Healing -Increases strength Gate of Life -Increases blood flow, turns skin red with bulging veins Gate of Pain -Increases Strength, your muscles may start to tear Gate of Limit -Increases strength further than the gate of pain, you start to fracture your bones Gate of View -Further increases strength, you can now move so fast that the friction in the air produces flames Gate of Wonder -Your strength increases to such an extent that your muscle fibers start to rupture Gate of Death -By puncturing your heart with your thumb you unlock the 8th gate of death, your strength is increased 100 fold, however the amount of chakra flowing through your body evaporates your blood (causing a red aura-like mist to surround you), and will slowly cook your body, there is a near 100% chance you will die.
As a freebie, you gain mastery of the Strong Fist Taijutsu style like that of Might Guy or Rock Lee.
