Naruto, born from the world of his parents.

"The reason you're so enthusiastic about this technique is because you've suffered a lot of losses. Because there's no distinctive smoke, it's hard for you to distinguish between the clone and the original."

Upon hearing Naruto's words, Sasuke nodded, his eyes burning with renewed fervor.

Seeing the eagerness in Sasuke's eyes, Naruto smiled and formed a hand seal.

Sasuke quickly looked at Naruto's hand, but as he looked, his brows furrowed.

"These... are the hand seals for the Shadow Clone Technique?"

Naruto's hand seals were very simple, or rather, there were no hand seals at all. He simply put his hands together and created a shadow clone.

This wasn't the first time Naruto had used this modified Shadow Clone Technique in front of him. Sasuke had previously thought it was because Naruto had simplified it, but now, seeing Naruto's demonstration, Sasuke realized he was wrong.

"Why does this shadow clone only have one hand seal? Why does it contain so little chakra and have no fighting power whatsoever? Are you curious about that?"

"right."

Naruto smiled and said, "This is what I told you: the essence of a ninja is simply someone who wields power."

After saying that, Naruto didn't rush to answer but instead posed another question: "Sasuke, what do you think is human nature?"

"nature?"

Upon hearing this question, Sasuke paused for a moment, but soon, a blood-red moon crawled out of his memory.

Bloodshed, wails, and those blood-red eyes that looked down on ants.

However, this time, the images in his mind did not cause Sasuke to lose his mind.

Although he gritted his teeth and trembled with rage, he forced himself to remain conscious and replied, word by word, "Betrayal, selfishness!"

Naruto wasn't surprised by Sasuke's answer at all. He simply looked at him quietly and softly asked, "Anything else?"

besides?

Sasuke's Sharingan had appeared silently at some point. He gritted his teeth, and the tomoe in his eyes spun wildly. The darkness in his memories kept surfacing in his mind as the tomoe spun, gradually eroding his hard-won clarity.

Just as he was about to be completely enveloped by the darkness, a warm hand covered his hair, followed by Naruto's familiar voice.

"Live on, live safely, live better."

The voice seemed to possess a certain reassuring magic. As Sasuke listened to Naruto's voice, he stared blankly at Naruto, who was bathed in sunlight, and the crimson in his eyes gradually faded.

"Survive?"

"Yes, to survive is human nature. Whether you are kind or selfish, whatever kind of soul you are, you ultimately follow the instinct to survive, to survive safely, and to survive better."

"This is also my original intention for improving ninjutsu, to make ninjutsu a guarantee for my survival instinct."

These words sounded somewhat like someone who was afraid of death, but when Naruto said them, they had an inexplicable sense of correctness.

Sasuke frowned, seemingly wanting to accept the idea, but in the end he shook his head.

"I'm sorry, Naruto, but I still can't agree."

"What's the reason?"

Sasuke gritted his teeth, his voice filled with deep-seated hatred, and said, word by word, "For me, the meaning of my life is to kill that man, to avenge my parents and my clan! As long as I can achieve this goal, even if it means death, I will never regret it."

Naruto's smile grew even gentler upon hearing this, but it was incredibly irritating to Sasuke. He frowned, about to ask a question, when he heard Naruto say this.

"So, is there any fundamental difference between what we're talking about?"

"What?"

Naruto smiled and asked again, "Aren't we talking about the same thing?"

"The reason people have to live is not just because of life itself, but also because of what they can do while they're alive, right? If he dies before achieving his revenge, or is killed by his enemy during the process of revenge, is that the kind of death Sasuke wants?"

"Of course not!"

"so."

Naruto smiled and narrowed his eyes: "Live well. Only by living to the end can you achieve your goal. Make ninjutsu your guarantee for survival and fulfilling your long-cherished wish. With this in mind, grow stronger step by step."

After Naruto's explanation, Sasuke's expression was clearly one of surprise. He instinctively wanted to refute, but found that he couldn't refute at all.

"Treating every battle with the utmost caution and achieving the greatest results with the least cost is the instinct of human beings, and it is also what you should do to accomplish your revenge."

After saying that, Naruto formed that hand seal again: "The first step is to learn to use common sense to confuse the enemy."

As soon as he finished speaking, another Naruto appeared silently beside him.

Sasuke's eyes widened in shock when he saw the two Narutos.

The two Narutos in front of him both had equally weak chakra.

"Are they all shadow clones?"

Just as Sasuke was wondering, Naruto, whose chakra reaction in front of him was extremely weak and who seemed to be a shadow clone, suddenly formed a hand seal.

Sasuke's eyes froze instantly upon seeing the handprint.

"This is?!"

As he expected, the sound of chanting incantations rang out simultaneously.

"Fire Release: Great Fireball Technique!"

Sasuke was completely stunned when he saw the fireball in front of him, which was at least ten meters in diameter.

"How could this be?! How could this happen?!"

After unleashing a clearly extraordinary Fire Release technique, Naruto turned to Sasuke and continued, "The second step is to exploit the enemy's misjudgment to create favorable conditions for the battle."

After saying this, Naruto turned into a wisp of smoke.

Sasuke instinctively walked to the spot where Naruto had disappeared, looking around. Suddenly, his whole body froze.

A kunai was gently pressed against his waist.

"The third step, the decisive battle."

Hearing Naruto's voice, Sasuke's eyes burned even brighter. He turned to look at Naruto, his voice trembling slightly, "You, when did you get behind me?"

Naruto put away his kunai and replied with a smile, "I never walked here; you walked up to me."

These words jolted Sasuke awake, and he instantly understood: "Transformation Jutsu?! That wasn't a clone; you used the Transformation Jutsu!!"

"Correct answer."

Naruto stretched and turned to look at Sasuke: "Now do you understand how to fight?"

He tossed the kunai in his hand and said softly, "Whether it's ninjutsu, taijutsu, or genjutsu, no matter how strong you are, as long as you stab the kunai into the heart, the battle is over."

This battle theory, which completely overturned Sasuke's understanding, made his heart pound uncontrollably.

He originally thought that the progress he had made in physical and ninjutsu training over the past few days had reached its limit, but he never expected that there would be new surprises waiting for him.

"You...you can teach me, Naruto?!"

"We're partners, aren't we?"
