Konoha: Naruto, trained by Aizen

However, since Naruto is currently under surveillance, he has not yet learned this ninjutsu from Minato.

Unexpectedly, Kakashi has taken the initiative to bring it up.

Then I have no choice but to respectfully comply.

"Then I'll have to trouble you, Kakashi-sensei."

"Before we begin learning, let's understand this ninjutsu." Kakashi led Naruto to the shade of a tree and began his earnest instruction.

"The Rasengan is an A-rank, no-seal ninjutsu developed by my teacher, the Fourth Hokage, over three years."

"The principle is to concentrate chakra in the hand, let it flow continuously in an irregular direction, and compress it to form a palm-sized ball of non-attribute chakra."

"Next, I'll demonstrate it for you."

Kakashi extends his right palm, palm facing upwards.

"Buzz." A powerful stream of air mixed with chakra swirled and condensed in his palm, gradually forming a beautiful little blue ball.

Its internal energy is not to be underestimated.

"This is the Rasengan." Kakashi pressed the Rasengan against the tree.

"Bang." Smoke billowed as a huge hole was blasted into a tree that an adult couldn't wrap their arms around.

If you were to press it on a person, wouldn't they be smashed to pieces?

"The power is not bad; at least it can make up for your shortcomings in ninjutsu." Kakashi withdrew his hand, his dead fish eyes remaining calm.

"That's a very powerful ninjutsu. I'll leave it to Kakashi-sensei then." Naruto gracefully brushed past the tree, causing it to slowly collapse and kick up a cloud of dust.

Having the destructive power concentrated at a single point is indeed a decent attack method.

"Next, I'll explain the principle to you." Kakashi nodded.

"The most difficult part of the Rasengan is controlling the irregular flow of chakra, making it form a balanced Rasengan in the palm of your hand without harming yourself."

"This ninjutsu requires a very high degree of control over chakra."

Kakashi broke down the key points of learning the Rasengan in detail.

These are the essence of what he summarized over a whole night.

"It is indeed difficult, Kakashi-sensei. It's really hard work that you can explain such a complex ninjutsu so clearly." Naruto couldn't help but praise Kakashi after listening to his explanation.

He extended his right palm, palm facing upwards.

"Om."

Under Kakashi's shocked gaze, chakra flowed and formed a small blue ball.

"Looks like it worked." Naruto smiled faintly as he gently tossed out the Rasengan.

"Bang." The Rasengan landed on the ground, its seemingly gentle chakra suddenly erupting like water thrown into a pot of boiling oil, stirring up the soil and bursting forth with fierce energy.

With a loud bang, smoke filled the air, and a crater was blasted into the ground.

"The power is not bad, but indeed, as the teacher said, this ninjutsu is very difficult." Naruto said in an extremely calm tone, as if stating a fact from God's perspective.

"This..." Kakashi was speechless for a moment, and could no longer maintain his calm and composed demeanor.

The Rasengan is...very difficult?

Is it really that high?

It seems like it took me a long time to master the Rasengan.

Those days were quite painful.

But how come Naruto...?

Kakashi began to have deep doubts about his own talent.

Then he saw Naruto flash a perfect smile, facing the rising sun, and extend his right palm.

"Perhaps I can also create a Kido similar to the Rasengan, which also controls irregular energy."

The words were spoken.

A small white ball spun rapidly in Naruto's right palm, and the terrifying energy contained within it made Kakashi's eyes widen in surprise.

"Is it chakra? No, it's not just chakra, it's a new development of his bloodline limit."

Kakashi's eyes gradually went from shock to numbness.

"Boom." A large tree was swept away by the white Rasengan and instantly exploded into ashes, leaving no trace of its remains.

Naruto's magnetic voice rang out in the air.

"Let's call it the Unmarked Kido, the Shadowless Rasengan."

At the same time, Minato's voice echoed in the sealed space: "The Limitless Demonic Path of Heaven, the Limitless Shadowless Escape, the Rasengan of Daylight Awakening."

Chapter Sixty-Two: The Mission

What should I do if my disciple is too talented?

Kakashi watched blankly as Naruto continued to practice the Rasengan. The originally plain blue Rasengan was gradually transformed by Naruto with different chakra natures, producing different chemical reactions.

Kakashi quietly put away the notes he had made the night before.

Although I felt somewhat helpless, I was also filled with relief.

Naruto truly lives up to his teacher's reputation as a son; his talent is astounding.

That way I can rest assured.

However, as a mentor, I didn't feel a great sense of accomplishment.

But compared to Naruto's growth, none of this matters.

At that moment, Naruto noticed Kakashi's somewhat frustrated look. He put away his Rasengan and gave Kakashi a gentle smile.

"Kakashi-sensei, thank you so much for your careful instruction. Without your clear and concise guidance, I think it would have taken me several days to master this ninjutsu."

Naruto's gratitude made Kakashi feel a little better.

He looked at Naruto.

A gentle breeze stirred, lifting Naruto's long, golden bangs and revealing his pure, azure eyes.

His eyes were filled with genuine gratitude.

At that moment, Kakashi's heart suddenly felt warm.

He recalled Iruka's assessment of Naruto:

"Naruto is someone who can warm everyone's heart and take care of everyone. He is the sun for all of us."

He has a calm and gentle personality, and his demeanor is refined and gentle.

Naruto is a ninja who perfectly inherited the Will of Fire.

A smile appeared in Kakashi's eyes. He pretended to be frustrated and rubbed his forehead, saying in a lazy and slightly exaggerated tone, "Looks like I've hit the jackpot and picked up such a talented disciple."

"Then I'll look forward to your guidance from now on, Kakashi-sensei," Naruto replied with a smile.

The master and disciple exchanged a knowing smile, everything understood without a word.

......

Compared to Naruto's smooth sailing, Sasuke and Sakura faced numerous difficulties.

First, there's Sasuke.

After a brief demonstration of ninjutsu, Kakashi discovered several major problems with Sasuke.

First, his control over chakra is not good enough.

It's understandable that most children at this age are restless, and for them, chakra control is a boring basic skill that they try to avoid training.

Although Sasuke also trained in chakra control under Naruto's influence, the results were not very impressive.

"Let's climb trees and wade in puddles first," Kakashi said calmly, pulling down his mask.

Next is Sakura.

Sakura's exceptional chakra control startled Kakashi.

However, Sakura, who comes from a commoner family, doesn't know much about ninjutsu. Compared to Naruto and Sasuke, she is only good at theory, but extremely weak in actual combat.

Kakashi earnestly asked Sakura for her opinion.

The girl looked somewhat confused, but soon seemed to have thought of something, her expression hardening as she answered firmly, "I want to learn medical ninjutsu."

"Medical ninjutsu? I happen to have mastered the basics of medical ninjutsu." Kakashi decisively taught Sakura how to use basic medical ninjutsu.

Sakura's choice aligns with the growth plan he formulated last night.

All three began their cultivation.

Kakashi quietly watched the harmonious scene and nodded silently.

Although Sasuke and Sakura have less-than-ideal personalities, they share Naruto's desire to become stronger.

Such a team.

They are relatively easy to take care of.

.....

A month later.

"Kakashi-sensei, please! We're sick of doing D-rank missions. How can you bear to let us waste our time on these missions?" Sakura cried, grabbing Kakashi's arm and shaking it wildly. Unfortunately, she was too weak to break Kakashi's arm.

"Hmph, what a boring request. Kakashi, I'm going to leave the village for a mission." Sasuke still had a smug look on his face, not even bothering to use the word 'teacher' anymore, which clearly showed his displeasure.

"Smack." Sasuke's head was knocked to the side as expected; the one who struck him was none other than Naruto.

He looked at Sasuke with a smile and said gently, "You must respect your teacher, Sasuke."

"Hmph." Sasuke, knowing he was in the wrong, blushed and snorted coldly.

'This team is a bit difficult to manage.' Kakashi's deadpan eyes showed helplessness as he gently pulled his hand away from Sakura's.

He refused the request in a lazy tone: "No, you're all too impatient right now. It's not time to leave the village yet."
