Naruto: the Rigid Fist Defeats All Methods

[Naruto fan] [No system] [No heroine] [Hot-blooded] [The protagonist is not familiar with the plot] With his soul traveling through Konoha, Sendo Arashi Tetsu has twenty years of martial arts and boxing skills, but he doesn't take the shortcut of Ninjutsu illusions. He restrained his chakra to the extreme, tempered steel and iron bones, created mountains of strength, opened up the realm of steel fists, entered the Tao with martial arts, and forced himself into a world where ninjutsu was supreme, carving a path to becoming a god with physical skills! After three battles, he became famous and made good friends with Minato, but he was unable to stop the Nine-Tails Rebellion, so he could only leave with the secret order. After the death of the third generation, Tsunade was called back. Faced with Danzo's pressing pressure, he overturned the shady curtain, broke the deadlock with his fist, and ascended to the top of Konoha's power. When Pain arrived, he defeated Super Shinra Tensei with one punch; under pressure from the ninja world, he teamed up with Madara to sweep the four shadows; when the six paths fought, he tore apart Kaguya's space with [One Power to Break All Laws]! To unify the ninja world, he revolutionized the past and established a new order of workers and peasants alliance; when Otsutsuki invaded, he suppressed it with a snap of his fingers, seized the power of eternal life, resigned from power, and flew into the universe alone. This is the legend of a commoner boy who, with a pair of iron fists, broke all the rules and walked from Konoha to the Star Sea!
