Synthesis Ninja system

Naruto Uzumaki, without any caution, complained as he rushed to open the door.

Shiro's pupils shrank to pinpoints, realizing it was too late to stop him!

As the door opened, a black cloak with red clouds blocked the entrance.

What stood out the most was a pair of blood-red pupils, catching immediate attention.

"I didn't expect the Nine-Tails to be sealed in such a small body!" Kisame Hoshigaki stepped forward with a smile, but when he spotted Shiro inside the room, his brows furrowed.

"I almost forgot about this guy! Itachi, you keep an eye on the Nine-Tails. I need to see how strong you really are at twelve years old!"

"Don't make too much of a scene," warned Itachi.

"Leave it to me!" Kisame grinned smugly, drawing his Samehada sword and charging toward Shiro.

Shiro's face twitched.

His presence had clearly altered the storyline! Originally, Sasuke Uchiha should have appeared shortly after their arrival, but now Sasuke was nowhere to be seen!

*Ding dong!* Task choice triggered!

1. Subdue Naruto Uzumaki! Reward: Intermediate Sage Body!

2. Escape with Naruto Uzumaki! Reward: Intermediate Taijutsu Mastery!

3. Defeat Kisame Hoshigaki and Itachi Uchiha! Reward: Kekkei Genkai: Byakugan!

Shiro's face twitched again. He usually chose tasks based on the rewards, but this time, even though the reward was an Intermediate Sage Body, he couldn't claim it!

Subduing Naruto would be easy, but Jiraiya would arrive soon after and surely kill him!

As for defeating Kisame and Itachi, that wasn't even worth considering. Escaping was the best possible outcome!

"I choose number two!" 

As soon as the words left his mouth, Shiro's muscles began to ripple as if they were breathing, absorbing the chakra around him.

In an instant, Shiro felt a surge of power fill his body. With one punch, he could easily shatter rock.

Kisame had already closed the distance.

Without hesitation, Shiro ducked and launched a 45-degree kick upward.

Kisame didn't have time to react. The kick landed squarely on his stomach, forcing him back several steps before stopping.

"Itachi! This kid really is a genius! This morning, he wasn't nearly this fast, but now he's improved so much in just one day!" Kisame wasn't angry; instead, he looked thrilled.

Even Itachi turned his head slightly, his eyes flickering with thought.

"Kid! You've made great progress, but facing me is your biggest mistake!" Kisame grinned confidently and dashed right up to Shiro!

Just as Kisame was about to strike, Itachi, who had been silent until now, suddenly spoke.

"Kisame! Come back!"

Kisame, just inches from striking Shiro, was baffled by the sudden command but, trusting Itachi completely, he immediately leapt back.

*Boom!* 

Shiro's body swelled up like a balloon before exploding!

Kisame's eyes narrowed in seriousness.

If Itachi hadn't warned him, he would've been caught in that explosion!

Though the blast wouldn't have killed Kisame, given his tough physique, no one wanted to deal with unnecessary injuries!

"Damn, I underestimated this kid. He even knows your Explosive Shadow Clone Jutsu!" 

"This kid isn't ordinary. He managed to take the Nine-Tails while causing the explosion!" Itachi remarked.

Kisame quickly looked down.

Naruto Uzumaki, who had been cornered earlier, had vanished!

"Damn it, go after them!" Kisame growled, irritated.

He couldn't believe one of the Seven Ninja Swordsmen of the Mist was being toyed with by a mere kid. If word got out, it would be humiliating!

"No need," Itachi said calmly, without a hint of emotion.

Not far away, around a corner, Naruto and Shiro were retreating, their eyes filled with reluctance.

Moments later, a young man in a black cloak with red clouds emerged from the shadows. Upon closer inspection, it was none other than Itachi Uchiha!

"Hahaha, I was worried for nothing. Who can escape your eyes?" Kisame laughed, shouldering his Samehada. "That Uchiha kid is mine; you take care of the Nine-Tails brat!"

Itachi said nothing, signaling his agreement.

With that, Kisame rushed toward Shiro again!

Shiro forced a bitter smile. In such a confined space, Kisame's Samehada couldn't unleash its full power.

But even in this tight space, Kisame's abilities far surpassed Shiro's, leaving him with little hope but to fight to the death!

"Damn it! I'll have to gamble!"

After studying the synthesis system, Shiro discovered that no matter how techniques were combined, their basic properties wouldn't change!

For example, the Reverse Flow Wall was a combination of Earth and Water!

Even if they weren't synthesized, the Earth Dragon Bullet and Water Dragon Bullet would just create a muddy mess, but after synthesis, their power increased several levels!

The signature jutsu of the Fourth Hokage, Minato Namikaze, the Flying Thunder God Technique, used a tag on kunai for spatial jumps!

By that logic, if Shuriken Jutsu was combined with the Body Flicker Technique, wouldn't that result in the Flying Thunder God Technique?

*Synthesize!* Body Flicker Technique and Shuriken Jutsu!

*Ding dong!* Custom jutsu being identified!

*Ding dong!* Identification successful! Synthesis success rate: 7.5%, failure rate: 92.5%. Remaining synthesis attempts: 1. Proceed with synthesis?

Shiro's face turned dark.

Previously, his lowest success rate for jutsu synthesis had been 60%, with most at 100%! 

But now the success rate wasn't even 10%!

However, he had no other choice.

"Synthesize! Do it now!"

*Ding dong!* Synthesis in progress!

*Ding dong!* Synthesis successful!

*Ding dong!* Jutsu obtained: Flying Thunder Break Technique!

When he heard the word "successful," Shiro was ecstatic!

But when he saw the jutsu description, his face darkened again.

"Flying Thunder Break? What the heck?!"

*Ding dong!* Flying Thunder Break allows the user to jump short distances by marking a shuriken as a coordinate. However, due to temporary blockages in the body's chakra pathways, the technique cannot be used consecutively in a short time!

Shiro's lips curled into a smirk.

This was essentially a nerfed version of the Flying Thunder God Technique!

It just added casting range and cooldown limitations!

But the core effect remained the same!

"There's a chance!"

Kisame was closing in on Shiro, but when he heard Shiro mutter to himself, he shivered and quickly retreated!

"Damn it! Another Explosive Shadow Clone Jutsu?!" Kisame grumbled, glaring at Shiro.

But after a while, the explosion never came.

Realizing he'd been tricked again, Kisame was furious.

"You brat, I'm going to kill you!"

Shiro chuckled nonchalantly and took out a kunai from his pouch.

After forming several hand seals, the black kunai emitted a golden glow, flickering brightly.

"Success!"
