Naruto: in Charge of Mikoto, the Magic Ball Explodes the Eight Gates Dunjia

Ren Asagiri, a time traveler, was reborn in the ninja world for eighteen years. She thought she could only be a cannon fodder genin and wait to die. Until that day - the [Medical Ninja System] was successfully bound. As long as the strong one is treated, the magic ball can be fired. Heals Jonin and drops a golden orb—— As a result, all the wounded in Konoha became his "reward pool". Uchiha Mikoto was seriously injured and was hospitalized → Obtained the golden magic ball and obtained [Magic·Tree Binding Kill]. Ten thousand years of genin Maruhoshi Kosuke's eye surgery → the golden ball fired [Water Dragon Bullet]. Matt Dai's body collapsed and he was sent to the hospital → The golden magic ball exploded directly into the [Eight Gate Dunjia]! In just one month, chakra increased from 500 to 11,750, A-level medical ninjutsu was at his fingertips, and S-level illusion swordsmanship was directly mastered. What's even more outrageous is that on a C-level mission, a copy scroll directly copied Nagato's Rinnegan! Chakra surges sevenfold, and all attributes change instantly. Purple ripples slowly rotated under the eyes. Once these eyes were opened, the entire ninja world would be shaken. "I don't want to be Hokage, I just want to live a good life." "By the way... Change the ending of the Third Ninja War in advance." ——What is blood profit at the beginning? This is called making a profit at the beginning.
