Naruto: Binding Uchiha Sasuke, Hundredfold Return

Back to Kazuki Sasuke, after being taught a lesson by Kazuki, Sasuke put away his arrogant spirit and continued to practice.

Under Kazuki's guidance, Sasuke began to develop a new lightning ninjutsu based on Chidori. The goal was to create a powerful enough S-rank ninjutsu!

At the same time, aside from slacking off and flirting with girls every day, Kazuki actually began to explore new ninjutsu! Of course, this was no easy task. Kazuki's so-called research on ninjutsu mostly involved lying on a bench in the training ground and playing with chakra.

For example, Fire Style: Fire Fist and Lightning Style: Thunder Fist—both techniques could be released without hand seals and were capable of destroying all objects within a radius of dozens of meters.

There were also Fire Style: Fire Sword and Lightning Style: Thunder Sword, which could replace swordsmanship moves in case you didn't have a weapon on hand.

Then there were Fire Style: Fire God and Thunder Style: Thunder God, two techniques that Kazuki considered failures but hadn't abandoned. These techniques used giants formed from fire and thunder to fight. Though they weren't very practical, they were certainly impressive. Even Sasuke was shocked when he first saw them, thinking that Kazuki had developed an incredible S-rank ninjutsu. However, in reality, these jutsu had the form of S-rank ninjutsu but lacked their power.

Kazuki classified them as failed ninjutsu!

And these weren't the only ninjutsu that Kazuki failed to develop. He also tried to fuse the lightning and fire attributes to create a new ninjutsu, but there seemed to be some underlying rules he couldn't grasp. No matter how Kazuki controlled his chakra, he couldn't make it work.

He thought about asking Sasuke to help develop these jutsu, but Sasuke's control over chakra wasn't as refined as his, nor did he possess as much chakra. So he couldn't rely on Sasuke.

"Chidori: Sharp Spear!"

As Sasuke thrust the lightning spear at a wooden stake, a voice echoed in Kazuki's mind.

[Ding! The object you are bound to has developed the Ninjutsu Lightning Release: Chidori Sharp Spear]

[You receive a hundredfold return... Lightning Release: Chidori Sharp Spear proficiency +100, current proficiency level: Proficient]

"Chidori... How about I make a Rasengan?"

Kazuki recalled that the first time Naruto was able to fight Sasuke on equal footing was when he mastered the Rasengan. The Rasengan is an attributeless ninjutsu, and Naruto could fuse Wind Release into it. So, could he fuse Fire Release and Lightning Release?

After completely mastering the changes in the nature of fire attribute chakra, Kazuki thought that S-rank ninjutsu would be easy. Just like the previous Great Fire Annihilation—more chakra meant greater power. Kazuki assumed that this was the difference between S-rank and B-rank ninjutsu, but the failures of Fire Style: Fire God and Thunder Style: Thunder God showed him that this wasn't the case.

The gap between S-rank and other levels of ninjutsu was definitely more than just chakra quantity!

If Naruto could fuse Wind Release with Rasengan to create an S-rank ninjutsu, why couldn't he fuse Thunder Release and Fire Release?

"Maybe I should give it a try!"

Kazuki thought it was worth a shot, so he began recalling the training method for Rasengan in his mind.

"The first stage seems to be to integrate the chakra into the palm..."

As Kazuki muttered to himself, his hands began to move. As chakra condensed in his palms, a chakra ball with no attributes appeared.

"Huh? That was easy!"

Kazuki was surprised at how easily he could do it. Could it be due to his chakra control?

"The second stage is to rotate the attributeless chakra inside a water-filled balloon until it bursts."

"Sakura, could you please buy me some balloons?"

"Of course, wait for me! I'll be back soon!"

Sakura, who often visited Kazuki during her free time, was quick to help. Ino was busy helping her family sell flowers today, and Hinata was training with her father, so only Sakura was available to run errands.

If Sakura wasn't around, Kazuki would have had to ask Sasuke, who was still busy mastering the newly developed Thunder Release: Chidori Sharp Spear. But if Kazuki asked, Sasuke would still put down his practice to run errands—that's how much respect Kazuki commanded!

After a while, Sakura returned with several balloons.

"Kazuki-kun, I brought the balloons."

"Thank you. Could you please fill them with water?"

"Of course, just a moment!"

Sakura quickly ran to a nearby stream to fill the balloons with water. Soon, several water-filled balloons were placed beside Kazuki.

"Is there anything else I can help you with, Kazuki-kun?"

"No, thank you. Take a rest. You've worked hard."

"It's no trouble!"

Sakura smiled and then sat next to Kazuki. "Let me massage your legs."

"Well, thank you."

"It's not a problem!"

Sakura said earnestly as she began massaging Kazuki's legs. You never know how eager a girl can be to help!

Kazuki enjoyed Sakura's massage while focusing on the second stage of the Rasengan training.

"Stable and continuous release of chakra... Spin, spin!"

Bang!

As the water balloon exploded, it meant that Kazuki had completed the second stage of training.

"Strange, why is this so unexpectedly easy? Am I not a failure after all?"

Kazuki was filled with confusion. Before bonding with Sasuke, he had struggled with even basic ninjutsu. Now, he could easily complete training that even Naruto found difficult. Had he unknowingly become a genius?

Ninja talents are generally divided into categories such as elemental affinity, chakra quantity, physical strength, taijutsu, ninjutsu proficiency, kenjutsu, chakra control, and bloodline limits.

Before bonding with Sasuke, Kazuki's talents were poor across the board. But after bonding with Sasuke, all of Kazuki's weaknesses were compensated for.

Possessing top-tier chakra attributes in both lightning and fire, along with immense chakra reserves and physical strength, Kazuki had reached the level of a Kage by the age of ten!

Thanks to the feedback from numerous ninjutsu, Kazuki had mastered the nature transformation of both lightning and fire chakra. Any ninjutsu of these attributes was easy for him to learn. And with his exceptional chakra control, non-elemental ninjutsu was also simple to master.

In terms of kenjutsu, Kazuki had already become a master of Konoha, Gekko, and Uchiha styles!

In terms of bloodline, he possessed the top-tier Uchiha bloodline, with his Sharingan having been enhanced a hundredfold to two tomoe!

In other words, Kazuki had become a true genius!

Even if he were to be unbound from Sasuke, Kazuki could still reach Kage-level strength on his own through training!

However, surpassing the Kage level would still be challenging. Without Sasuke's feedback, his physical and chakra growth would slow. Whether he could still reach the transcendent level remained to be seen.
