I! the Kendo Genius Behind Konoha White Fang

Yundu, who travels through the world of Naruto, is bound to a system that makes him stronger by swinging a sword. Each time you swing the sword, you will be one point stronger than the last moment, and it can also improve the progress of various swordsmanship templates. Completing 100,000 sword swings will also reward you with a Zanpakutō. Hatake Yundu was silent... Do you believe me when I say I have eight livers? Yundu's swing of the sword lasted for ten years. Just when the whole village thought that Yun Du was not normal, Hatake Sakumo, known as Konoha White Fang, was kneeling in front of him and asked Yun Du to teach him swordsmanship. Hatake Sakumo: "My brother is a genius who can become stronger by touching a sword! It's just that it's quite extreme." Shimura Danzo: "I asked Hatake Undo to join me, but that guy actually said that joining Gen would only affect the speed of his sword swing?" Uchiha Madara: "Seriously, he is the first person who can split my Susanoo with a sword." Senju Hashirama: "What? You were also hacked?" This novel and its characters are purely fictitious.
