Naruto: Binding Uchiha Sasuke, Hundredfold Return

"Then wait until he surpasses me."

Kazuki said nonchalantly, "And Kakashi-senpai, if you don't work hard to practice, it won't be long before you'll be surpassed first!"

Kakashi: "..."

With Sasuke and Kazuki's talents, they might surpass him in the next few years.

Of course, the premise is that they can keep improving at the current speed.

Kakashi didn't believe that Sasuke and Kazuki could maintain this pace of improvement. After all, they were only ten years old, and their physical fitness couldn't compare with his as an elite jonin.

Moreover, they were not from the Uzumaki clan, and their chakra reserves also limited their growth.

"Then wait until you surpass me, but now continue to practice!"

Kakashi returned Kazuki's words to him.

"Got it! Got it!"

Kazuki looked helpless, got up, and continued to study the relationship between fire attribute chakra and the technique.

However, after just a moment of thought, Kazuki felt tired.

He really had no interest in developing ninjutsu.

"It would be nice if there was a ready-made ninjutsu that I could copy."

"Hmm? Copy?"

Creating something from nothing was difficult for Kazuki, but it seemed much easier to go from one to two.

Carefully recalling the fire ninjutsu in his mind, he thought of: Fire Style: Big Flame Bomb, Fire Style: Ash Burning, Fire Style: Head Burning, Fire Style: Storm Dance, and others.

These were all B-level ninjutsu, differing in the shape of the flame and the attack range.

The Big Flame Bomb acted like a missile.

Ash Burning produced power in the form of an explosion.

Head Burning formed a sea of fire.

Storm Dance turned the flame into a vortex.

Thinking of this, Kazuki gathered a small chakra flame in his hand.

"Fire Style?"

"What if I enlarge this flame?"

Kazuki began to release more chakra, and a huge fireball appeared.

As he continued to increase the chakra, the fireball grew bigger and bigger.

When Kazuki threw it out, it caused an explosion, its power no weaker than the Great Dragon Fire Technique!

"B-level ninjutsu without seals?"

Kazuki found that he seemed to have done something incredible.

Why could he release ninjutsu without seals?

Did he unknowingly eat the Flame-Flame Fruit?

Kazuki thought about it carefully and attributed it to his control over chakra.

At this time, Sasuke's control over chakra had reached a very high level, with the training of treading water and climbing trees years behind them.

But Kazuki's control over chakra was a hundred times that of Sasuke!

"If I can completely control the chakra, does it mean that I can release any level of ninjutsu just by thinking about it?"

Although Kazuki had not learned fire release techniques above B-level, as long as he released enough chakra, even B-level fire techniques could exert the power of S level!

Just like Uchiha Madara releasing the Great Fire Annihilation!

After figuring this out, Kazuki played for a while, trying to turn the flames into sparks, fire bombs, fireballs, flame whirlpools, and many other shapes.

Kazuki even wanted to create a fire giant.

But even Kazuki's chakra wasn't enough to sustain this ideal fire giant for long.

Moreover, the defense and attack of this fire giant were average, and its existence had little meaning.

In the end, it was just a bluff!

Unless it was wrapped with a Susanoo inner... Nuclear!

In just one day, Kazuki completely mastered the changes in the nature of fire-attributed chakra. However, he did not tell Kakashi, because Sasuke still needed his teaching.

The next day, Kakashi wanted to check Kazuki's practice results.

As Kakashi wished, Kazuki demonstrated the "Lighter Technique" he developed!

The exquisiteness of this technique left Kakashi speechless, and he told him to keep working hard.

So Kazuki demonstrated "Lighter Technique 2.0" in the next few days. The lighters on two fingers could light two cigarettes at the same time!

After seeing it, Kakashi was amazed and told Kazuki to go aside and continue practicing.

On the third day, Lighter Technique 3.0.

On the fourth day, Lighter Technique 4.0...

Until the tenth day, Sasuke mastered the change of the nature of fire attribute chakra, enhancing the burning characteristics of flames, and increasing their temperature and lethality to a great level!

Kakashi asked him to stop studying fire release ninjutsu and start practicing the control of the change of lightning attribute chakra!

His task requirement was to teach Kazuki to master the change of fire and lightning attribute chakra, not to teach Kazuki to develop advanced ninjutsu.

In other words, the third stage of developing ninjutsu after mastering the attribute change was not what Kakashi needed to teach.

In addition, Kazuki's perfunctory attitude made Kakashi give up the idea of teaching Kazuki more knowledge!

He now just wanted to finish the task safely and steadily, so that he could have an additional B-level task value on his resume.

Such emotions made Kakashi no longer care about the task, so much so that he gave up his special care for Sasuke.

From this day on, Kakashi only told Kazuki and Sasuke about the training tasks every day, and spent the rest of the time reading books to pass the time.

Even Kakashi learned to be late and leave early, and was no longer the elite ninja of the Anbu who treated tasks meticulously!

If it were any other employer, they would definitely sue Kakashi for his behavior and demand a full refund of his salary.

But Kakashi had a similar idea, and Kazuki just appreciated this point about him and didn't make any accusations at all, which made Kakashi quite helpless!

Time passed quietly, and half a year had passed before they knew it.

In half a year, Sasuke finally learned the lowest level of Lightning Release Ninjutsu from scratch and mastered the changes in the nature of lightning-attributed chakra.

Kazuki mastered it several months earlier than Sasuke, but in order to give Sasuke more time to improve, he did not tell Kakashi that his mission was over.

Ding! The person you are bound to has mastered the ninjutsu Lightning Release: Chidori!

You get a hundred times the return... Lightning Release: Chidori proficiency +100, current proficiency is proficient!

"???"

Special treatment?

Was I backstabbed by the teacher I paid for?

Kazuki didn't expect Kakashi to become Sasuke's teacher.

He was perfunctory and careless when teaching him, and he even taught Sasuke his own unique skills!

Kazuki was a little speechless.

Kakashi was too partial!

But the other party had always disliked him, so it was not surprising that this happened.
