Naruto, I, Yahiko, Will Revolutionize and Unify the Ninja World.

1. Travel through time and become a dying Yahiko, activate the [becomes stronger by 0.001% Every day] talent, and you will be able to roll up the ninjutsu system when others roll it! Use mathematics to optimize chakra, use infrastructure to win over people's hearts, and use technology to defeat the old era - Hanzo's poisonous fog cannot stop the water purification plan, Madara's Tsukuyomi cannot stand up to the national awakening, and Otsutsuki's theocracy cannot defeat the federal constitution! From the sewers of Amegakure to the chairman of the Ninja World Federation, I, Yahiko, do not rely on words, but only rely on "rural areas surrounding cities" to turn troubled times into prosperous times, and turn the ninja world into an utopia where everyone has food to eat and books to read! (PS: All the villains have online IQs, the protagonist uses his brain to revolutionize, it's a bit more intensive without adding water)
