The Importance of Swordsmanship

Furthermore, his mother, Uchiha Eiko, had become even more powerful! Following the death of his brother Masatake—whom he had never known—Uchiha Eiko had awakened the Mangekyou Sharingan, which led to her premature labor and the birth of Kangetsu and Meigetsu. By all accounts, Uchiha Eiko should have been left on the brink of death, if not dead entirely. Yet, thanks to Kangetsu's influence, not only was her body strengthened, but the power of her Mangekyou had become terrifying.

Consequently, the strongest person in the household was not Uchiha Tajima, but Uchiha Eiko. This was why Uchiha Tajima obeyed her every word, and also why the Kangetsu household was so opulent. After all, when a family possesses two powerhouses who both rank among the top ten, they are naturally blessed with absolute material wealth.

With these thoughts, Kangetsu steeled his resolve. I must become a powerhouse, he mused. For others, the battlefield is a place of terror, but for me, it is a training ground. After all, the true method of cultivating the Killing Fist is to kill!

At that moment, the murderous intent deep within Kangetsu seemed to awaken. Suddenly, a voice reached his ears, snapping him out of his reverie.

Kangetsu looked up to see Izuna holding a sword and asking, "Father, why do you make us train in taijutsu and swordsmanship instead of teaching us ninjutsu?"

Kangetsu found this strange as well. After all, in this world of Naruto, ninjutsu was the mainstream. For Uchiha Tajima to be holding a sword and demanding they learn swordsmanship felt like complete nonsense.

However, Uchiha Tajima's eyes turned stern as he barked, "Do not underestimate swordsmanship! For you, mastering the blade is the key to survival. Anything can happen on the battlefield! You must kill your enemies as quickly as possible if you want even the slightest chance of keeping your own life."

"And the sword in your hand is the best way to kill quickly. In this world, aside from a few clans with special ninjutsu, most people are mere mortals of flesh and blood. Your swords can easily slit an enemy's throat."

"Anyone with a slit throat is as good as dead. Furthermore, swinging your sword only consumes physical stamina, not your chakra! Ninjutsu requires chakra as fuel; without it, ninjutsu is nothing more than a collection of memories. How much chakra do you even have right now? You'd be lucky to pull off a few Body Replacement Techniques!"

"So, focus on training your swordsmanship and taijutsu. When you are older and have sufficient chakra, then you can use ninjutsu against your enemies. For now, ninjutsu can only serve as a supplement, so stick to your physical and sword training!"

After speaking, Uchiha Tajima raised his own sword and shouted, "Remember, to swing your blade quickly and kill your enemy, you must know their weaknesses. This is a human model; the red dots are the enemy's vital points—the weaknesses of the human body. You must learn how to strike these points with your sword, while also learning how to protect your own vital points from being struck by the enemy!"
