I, Uchiha Yu, am solely focused on cultivating immortality

Chapter 45 Swordsmanship in the Warring States Period

"Uchiha Yu, the old man is very satisfied with the tofu you made. I have a sword technique, I'll teach it to you."

"Okay, thank you, Uncle Xin Yin."

"There's no need to thank me. I don't have much time left. It's not a waste that I can pass on this sword technique to you."

Uchiha Shin'in walked to the center of the courtyard, pulled out a long sword from somewhere, and instantly straightened his old, hunched body. The old man exuded a strong killing intent, and there was a strong smell of blood in this killing intent.

The smell of blood wasn't real. Uchiha Yu could smell it, while Shisui could only feel a chill run down his spine and couldn't help but take several steps back to avoid the area affected by the killing intent.

Uchiha Shin'in sighed, "I'm getting old. Just picking up a sword isn't enough to control my killing intent."

It was only then that Uchiha Yu realized that the old man's sword was a double-edged sword, which delighted him. He preferred straight swords that were good for thrusting, rather than the curved samurai swords that were popular everywhere.

The popularity of the katana is not without reason. When neither side in a battle wears armor, or only light armor, the katana's slashing and bleeding effect is enough to cause fatal damage.

However, Uchiha Yu knew that the biggest advantage of the sword over the knife was the cost of production and training. But when it came to one-on-one combat, the sword had far more ways to attack than the knife, and piercing attacks were far more deadly than slashing attacks.

To be able to receive guidance from a ninja who fought his way through the Warring States period is a lucky thing, and to have a ninja whose fighting skills perfectly match one's preferences is an incredible stroke of luck.

Uchiha Shin'in slowly wielded his longsword, making one move after another, leaving Uchiha Shisui bewildered, and Uchiha Yu was equally confused.

So he raised his right hand, touched his brow with his index finger, and cast a simple genjutsu to conceal his three-tomoe Sharingan. He carefully copied the old man's every movement and used his brain to analyze every detail of these movements.

The more you analyze it, the more confused you become; these actions don't actually have strong lethality.

But could it be a joke that an eighty-year-old man, dragging his frail body and panting heavily, is demonstrating his swordsmanship to himself?

Impossible, absolutely impossible.

This is the Uchiha clan, Uchiha ninjas from the Warring States period.

They are proud to the core. They might joke around with their children and grandchildren while drinking, but after such a formal explanation, they will never joke again.

Suddenly, a thought flashed through Uchiha Yu's mind. He considered the old man's entire body as a whole, and then he could see a different flavor in these slow movements.

Ultimately, all sword techniques in the world lead to the same goal, albeit through different paths.

Uchiha Shin'in has many movements, but they can be summarized into only eight types according to the way he exerts force: pointing, thrusting, chopping, sweeping, intercepting, wiping, flicking, and blocking. Among them, pointing and thrusting are used the most. He thrusts and lightly points from different angles and heights. The other movements serve these two, either as a connection between two thrusts or as a way to turn into a thrust or point after defending against an enemy's attack.

This is completely consistent with the basic movements of Chinese swordsmanship, only the number of techniques is not as many, and the offensive power is excessively strong.

Due to his advanced age, his memory had deteriorated. Sometimes, Uchiha Shin'in would stop to think before continuing to swing his sword, and sometimes he would make the wrong movements, thus repeating the same action. Shisui watched, completely bewildered, unable to comprehend the old butler's swordsmanship.

The old man slowly completed all the movements, then, slightly out of breath, asked, "Have you memorized them all? Did you understand them?"

Shisui nodded and then shook his head, indicating that he had memorized the movements, but he couldn't understand them at all.

The old man patted his head: "It's okay if you don't understand now, young master. You're too young. Just remember it, and you'll understand it slowly in the future."

When Shin-in looked at Uchiha Yu, Yu nodded and said, "I've memorized all the movements, and I roughly understand them, but I didn't see the transitions between the movements at the beginning very clearly."

"You actually understood it!" Uchiha Shin'in was pleasantly surprised and praised with satisfaction, "Good, very good. Almost there, then I'll do it again for you."

"Watch carefully, I don't have the energy to demonstrate a third time."

"Hmm, I just did it once, and I remembered a lot of things. I should be able to demonstrate it even better this time."

Upon hearing this, Uchiha Shisui watched with even greater concentration, but he was surprised to find that the old butler's movements were completely different from the last time. In fact, each movement was very similar, but they were just different, and the order of the movements had changed from beginning to end. Shisui was completely confused, his brain was about to turn to mush, and in the end, he could only force himself to memorize them.

Uchiha Yu was also remembering, but he had the copying ability of the three-tomoe Sharingan, making it much easier for him to remember than for Shisui. This allowed him to relax and think and analyze, verifying the ideas he had just come up with.

Thinking back to the sixth set of radio calisthenics in elementary school and the seventh set in junior high in his previous life, Uchiha Yu realized that it would take him several weeks to barely memorize the movements. He thought the Uchiha clan was pretty good. Putting aside their handsome faces and great bodies, just the abilities of their Sharingan alone would make other clans extremely envious.

Yes, there's a reason why the Uchiha clan doesn't get along well with other clans.

I hate those cheaters around me the most.

……

After a delicious meal and mastering swordsmanship, the afternoon training was completed by sunset, and Uchiha Shin'in was about to take Shisui home.

Before leaving, the old man told Shisui to go out first, and then turned back to say a few words to Uchiha Yu: "Yu, I hope that after Shisui awakens his Sharingan, you will teach him this sword technique."

"Of course." Uchiha Yu realized the old man was certain he had the Sharingan, and asked, "Is there a problem with my genjutsu?"

"No, the illusion technique is fine, but this sword technique can only be learned quickly by activating the Sharingan."

"Ah, it was my oversight."

"Haha, it's good that you know how to hide your strength. You still need to pay attention to these details. Besides, your eye power is too strong. Even with the simplest copying ability, it still makes quite a commotion."

"So there was also a leak of pupil power, I understand now."

The surge in mental energy nourished the eyes, resulting in some of the pupil energy exceeding the controllable range and unconsciously dissipating. This is no small problem and must be resolved immediately.

If others find out, especially Root ninjas, that would be troublesome.

Fortunately, this time it was Old Man Xin Yin who found out. He is very tight-lipped and his secret will not be revealed.

Thinking of this, Uchiha Yu bowed to the old butler and thanked him, saying, "Thank you. I will keep my promise. After all, I also like Shisui very much, so I will naturally take care of him."

"Okay. I'm relieved to hear that."

"Shisui is just like his grandfather—too kind and too naive. I'm worried he'll die like Jing, without knowing why."

"That kid Uchiha Kagami is so young, yet he's stronger than this old man. He's invincible on the battlefield, but..."

Looking at the dejected old man, Uchiha Yu finally couldn't help but sigh, "The human heart... has always been more dangerous than the battle itself... Damn!"

Before he could finish speaking, Uchiha Yu noticed something was wrong with Uchiha Shin'in, who had looked up.

The old man's eyes were full of pride, and there was not a trace of sadness on his face.

I've been scammed!!
