Naruto: No Harm to the Eight Gates, One Kick to Crush Susana!

Traveling through Naruto, he became an ordinary six-year-old orphan of the Uchiha clan. Seeing that the countdown to the "Night of Genocide" was less than one year, and the "filial son" named Uchiha Itachi was about to raise the butcher's knife, Uchiha Xin was completely panicked. Escape? Konoha Anbu is not a vegetarian. Tell the truth? Danzo's jar of formalin was already thirsty. Fortunately, at the critical moment of life and death, the [Extreme Sharingan System] awakens! As long as you use the Sharingan crazily, you can increase your proficiency and evolve infinitely, including single magatama, kaleidoscope, and even the samsara eye! But as a six-year-old child, what should I do if I have very little chakra? Bite! At the beginning, draw the god-level passive [Enhanced Version of Eight Gate Dunjia]! No damage! No side effects! Stay on permanently! The most terrifying thing is that every time a door is opened, the upper limit of chakra increases three times! While others were still practicing the seals hard, Uchiha Xin had already begun the journey of crushing the Yakuza with a unique style of painting. Not enough chakra? Open the door! Insufficient pupil power? Open the door! One year later, the blood moon was in the sky, and the night of genocide came on time. Itachi Uchiha held the long knife dripping with blood and coldly pushed open the courtyard door, but he ran into a six-year-old child with all eight doors open, eyes scarlet, and chakra surging around his body like a tsunami. Seeing his cousin crush Susanoo with his foot, Itachi fell into deep self-doubt. "Brother, you just raised the knife... Who did you want to kill?"
