After hearing Tenbu Shinzo's explanation, Sasuke was not angry over his concealment. Instead, he laughed happily. Why was he so pleased? Sasuke did not know any swordsmanship at all. He had forged weapons more for the future use of ninjutsu, especially the development of Lightning Style Jutsu. The Sasuke in the anime had developed Lightning Style Jutsu to an incredibly high level, but that was only in the anime. In reality, Sasuke had no idea how to do it and could only experiment based on some of its applications from the anime. But as for swordsmanship, he truly knew nothing about it.
He had only learned his two fist techniques on a whim, and not long after he had learned them, before he had achieved anything with them, he had been stabbed more than a dozen times. He did not even know exactly why. Now, if someone gave him a sword and told him to fight with it, he would need to keep exploring and training. He originally had no direction, at most imitating the anime he had watched. But now an opportunity had appeared. With so many samurai and ninja competing... Sasuke suddenly thought of a question. "Can ninja use ninjutsu?"
"No. It can only be a pure contest of swordsmanship. It depends on swordsmanship, strength, and speed. That won't be a problem for you, right?" Tenbu Shinzo believed that since Sasuke had traveled all the way to the Land of Iron to forge a sword, he surely knew swordsmanship. He had originally intended to compete himself. After all, in the Land of Iron, blacksmiths all knew how to use swords, though their swordsmanship was generally mediocre. Still, he had tremendous confidence in the sword he had forged, so he dared to go up against others and trade blows.
