Naruto: Give up Ninja and Embrace the Sword! Establishing the Thunder Knife Era

He traveled through time and became the cannon fodder of Hokage. He has no blood inheritance, no secret skills, and even cheats are ten years late. The second ninja war was approaching, and he was going to the battlefield on his terms, not even being able to leave his name. But it took him five years to do three things - He broke ninety-nine swords, earned a net worth of two billion by writing pornographic books, and built a forbidden weapon that can kill Jonin with his bare hands. One billion taels smashed open the Raikage's door, and three muskets were slapped on the table. In exchange, he said to the Third Raikage: "From now on, you are my disciple." However, no one knew that this ten-year-old boy had another identity - a spy planted in the roots of Konoha. When Danzo's secret order was delivered, and when the dark clouds of the Ninja War came over, he made a decision that would overturn the world: Give up the seals and spells of ninjas, abandon the shackles of blood and fate, and use a mortal body to hold a sword against the sky! Thousand years of Ninja sect, the creation of Six Paths. Starting today, he will personally end this era of ninjas—— Extremely fast slashes, eight strikes per second, as powerful as a monster, and impossible to defeat in close combat. Not a ninja, but a swordsman. This is the era of thunder knives! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
