Konoha: Naruto, trained by Aizen

"Because he has his family's ninjutsu?" Sakura looked up blankly.

"No, he foresaw the cruelty of ninjas beforehand, which is why he was determined to become stronger."

"Bearing the honor of his family, he pushed his limits in the face of life and death. For him, being a ninja was not a child's game; it meant certain death."

Naruto took the kunai from Sakura's hand and said softly, "We might have needed to complete several more missions before entering this cruel phase. I'm truly sorry for bringing Sakura into such a cruel world without my consent. Until Sakura makes up her mind, I will bear all of this."

"After all, I'm used to the real world."

Naruto's tone was gentle, and his expression was tender.

"I..." Sakura trembled at the thought of her hands being stained with blood, and two lines of tears slid down her face: "I'm sorry, Naruto-kun, I was so naive."

"But, I... I still want to try. I don't want to hold anyone back." Sakura wiped away her tears and took the kunai from Naruto's hand.

"Really? Sakura, you're just as I thought, very strong." Naruto smiled and ruffled Sakura's hair.

"Then let's begin."

Kakashi watched this scene quietly, and couldn't help but sigh inwardly:

"I've gotten used to the reality. I guess the past was more cruel to Naruto than killing people."

"Only after experiencing pain can one learn to cherish."

"It is precisely because of this experience that Naruto was able to become such a dazzling light."

Chapter Sixty-Four: A Soul Filled with Resentment

"Hmm? Seems like I've stumbled upon something interesting?" Aizen, who had just appeared in the sealed space, looked amused.

"Naruto's first...kill?"

He pushed up his glasses, his eyes filled with anticipation.

"A fledgling eagle that has never experienced life and death will always remain a fledgling eagle. Having experienced the pain of childhood, will you become someone who indulges in and enjoys killing, or someone who controls killing?"

Aizen sat quietly on the mountain peak, letting the cold wind brush against his drooping hair.

My thoughts gradually drifted away.

I've been sealing the space less and less often lately, precisely because I've been too busy.

He saw in Naruto the potential to cultivate chakra and spiritual pressure simultaneously.

It is precisely for this reason that he has already begun experimenting with chakra on some of the Shinigami.

He first found a puppet human whose consciousness was being manipulated in the real world, and had him train in chakra, using special methods to extract the chakra into a container.

Then, through a series of tricks, he made several Shinigami "vanish" and injected the extracted chakra into their bodies.

However, what troubled him was that these Shinigami who had been forcibly infused with chakra all developed varying degrees of ulceration in a short period of time.

If the Shinigami is lucky, their body will not change, but their chakra will disappear in a short time.

Based on current experimental findings, Shinigami, whose bodies are composed of spiritual particles, are unable to cultivate chakra.

This was learned from the chakra system that Naruto learned.

It is a product of the balanced mixing of chakra spiritual energy and physical energy.

Chakra flows through the body's meridians, forming a perfect balance.

Does this mean that only those with human bodies can cultivate chakra?

Aizen had too many questions in his mind.

All of this needs to be answered by Naruto.

In the world of Bleach, the souls of the dead either go to Soul Society or become Hollows.

What about the Naruto world?

........

Coincidentally, Naruto was also contemplating matters related to the soul.

In his previous conversations with Aizen, he learned that Shinigami and Hollows possessed spiritual pressure within their bodies.

People with strong attachments have a certain chance of turning into nothingness after death.

This is different from the ninja world.

At least currently, there is no historical record to prove that a person may undergo different changes after death.

Moreover, in the world of Bleach, humans cannot see Shinigami or Hollows.

Even if Hollows truly exist in the ninja world, no human would be able to see them.

But Naruto is different.

Having cultivated spiritual pressure, he is considered half a Shinigami, and naturally he can see some supernatural objects.

This commission was also a testing opportunity for him.

Where do humans go after they die?

Is it possible to become the Grim Reaper?

These are all very interesting topics.

Thinking about this, Naruto couldn't help but feel a sense of anticipation.

"Shhhhh."

Several figures flashed by in the moonlight, accompanied by a slight whooshing sound.

Only the slightly swaying leaves remain.

Within the town.

Even the sentries on night watch were getting tired.

They weren't ninjas after all, and didn't have that level of vigilance.

Besides, the town has been captured for at least four days, so it won't matter if we slack off for a day.

The town was completely silent; if you closed your eyes and listened carefully, you could occasionally hear strange noises coming from inside the rooms.

This is a common tactic used by bandits.

After conquering a town, they squander and enjoy themselves to the fullest, then kill the inhabitants when they're done.

"Whoosh." Several dark figures flashed by. A bandit on night watch rubbed his eyes, still half asleep, thinking it was just his imagination.

But the next moment, he felt a chill on his neck. His eyes widened, and he groggily touched his neck. It felt warm, and some viscous liquid was constantly dripping down.

Enemy attack...

He clutched his throat, but couldn't make a sound. In his dying moments, his unfocused pupils saw a dark figure appear before him, its eyes cold and ruthless.

"Crack." Sasuke withdrew his hand and wiped the blood off the kunai.

Despite it being his first time killing someone, he was surprisingly calm.

"Itachi, did you feel this way when you slaughtered your own kind?"

Sasuke's eyes turned cold, and he disappeared from the spot, heading towards his second target.

"Sasuke is a born ninja," Kakashi thought to himself as he secretly observed.

Meanwhile, Naruto had already approached the house where the leader was.

Chakra was evenly distributed on the soles of his feet, allowing him to stand steadily on the ceiling, observing the sleeping leader upside down.

The leader was fast asleep, his chest bare.

Naruto was able to sense the extremely faint chakra within the leader's body.

This leader was once a ninja, wasn't he?

Naruto stood upside down like a bat, coldly observing the leader, his face devoid of any gentleness.

In the ninja world, the strongest are the ninjas in their villages, but for ordinary people, the most dangerous are the ants that are so weak that even the strong wouldn't bother to step on them.

It is precisely because they are weak that they become even more evil.

Naruto had learned from his knowledge of the modern world that strict laws could restrain the weak, reduce crime rates, and at least allow ordinary people to have a relatively peaceful life.

Unlike the ninja world, where the weak and helpless live in constant threat.

The strong disdain to actively protect the weak; only self-interest will drive them.

Just like Naruto now.

If it weren't for the commission, he wouldn't have come here to help Nightwish Town, which had been attacked by bandits.

"Buzz." With a soft hum, the Mirror Flower Water Moon appeared in Naruto's hand, gleaming with a faint green light under the dim moonlight.

With just a gentle wave, a vibrant life can be lost.

The thrill of controlling the length of one's life is intoxicating.

However, Naruto's eyes instantly regained their clarity.

Only the weak indulge in killing.

The dark green blade flashed across the leader's neck.

The room fell silent again. The leader's body did not move at all, except that his chest was no longer rising and falling. At first glance, he seemed to still be immersed in a dream, quiet and peaceful.

"Shh."

Naruto sheathed his sword, the still-smooth blade reflecting his thick glasses and the calm eyes hidden behind them.

“Well… boring.” He murmured softly, “Crushing a lowly ant only leaves an endless void, which is not what I want.”

He looked out the window at the cool moonlight, a hint of enjoyment finally appearing in his eyes: "The moonlight tonight is exceptionally enchanting."

Just then, Naruto noticed that a faint light suddenly emanated from the body of the dead leader, and then a luminous soul slowly emerged from the corpse.

This is... a soul?!

Naruto's eyes behind his glasses were filled with surprise and joy.

Aizen, inside the sealed space, also widened his eyes.
