Synthesis Ninja system

*Ding dong! System successfully bound! Please select your Kekkei Genkai!*

1. Byakugan 

2. Shikotsumyaku 

3. Ice Release 

4. Sharingan 

Shiro looked at the four options that appeared before him, instantly feeling a rush of excitement.

He had been watching *Naruto* and muttered, "Damn you, Kishimoto!" 

Who would've thought that a black hole would suddenly appear on his computer screen? 

And who would've thought he'd be transported into the world of *Naruto*? On top of that, he could choose a Kekkei Genkai right from the start!

Since he had to choose, he knew he had to be cautious!

Even though the Rinnegan wasn't available, the Byakugan was still known for its world-destroying power! 

However, Shiro thought of how the Byakugan made people look like cataract patients and shook his head.

The Shikotsumyaku was also insanely powerful! 

Back in the day, Kimimaro, even while on his deathbed, nearly killed Gaara with just one move. The sheer violence was terrifying.

But then Shiro thought about fighting with his own bones and the possibility of getting the bloodline disease. Kimimaro died from that, after all, and the thought sent chills down his spine.

As for Ice Release, it was the Kekkei Genkai of the Yuki clan from the Hidden Mist, created by combining Water Release and Wind Release. It had limitless potential, just like the First Hokage's Wood Release!

When Shiro saw the final option, Sharingan, he clicked without hesitation!

Though the Sharingan wasn't necessarily the strongest, it was definitely the coolest!

Why overcomplicate things? Coolness is all that matters! 

*Ding dong! You have successfully chosen the Sharingan. Fusion in progress, please wait!*

As the system's voice sounded, Shiro felt an intense pain in his eyes, as if countless ants were biting at them.

*Ding dong! Sharingan fusion complete! This is a system-generated product with no side effects. Please use it freely!* 

Shiro was ecstatic!

The Sharingan could copy ninjutsu, see through attacks, and break through illusions, but it had a fatal flaw!

Once upgraded to the Mangekyō Sharingan, using its unique abilities too often could lead to blindness!

Shiro had originally planned to use it sparingly, but now, with no side effects, he could use it as much as he wanted!

After selecting his Kekkei Genkai, the system went silent.

Only now did Shiro begin to observe his surroundings.

He was standing in a cluster of buildings, and when he looked up, he could see the faces of four people carved into a distant cliff!

The Hidden Leaf Village!

The architectural style and the statues on the cliff confirmed that he was indeed in *Naruto's* Hidden Leaf Village!

Shiro hadn't even had time to rejoice when suddenly there was a loud *boom*, and the ground trembled! 

Looking towards the source of the sound, he saw a massive snake crash through the high wall, wriggling its way into the village!

The Leaf was under attack!

Shiro cursed silently. He had just transmigrated, and the village was already being attacked. He hadn't even had time to meet any major characters, and now he was thrown into such a massive storyline!

The Leaf Village had been attacked four times in total: 

1. The Nine-Tails attack 

2. Orochimaru's invasion 

3. The Pain attack 

4. The Kaguya Ōtsutsuki incident 

Judging by the attacking forces, this seemed to be the second event, during the Chūnin Exams, when Orochimaru launched his assault!

Shiro let out a long sigh of relief. At least it wasn't one of the last two events, or he'd have no idea how he might die! 

As for the second event, it involved the Third Hokage!

The Third Hokage, Hiruzen Sarutobi, known as the "Professor of Ninjutsu," would meet his end here! 

"I have to go see this before it's too late!"

Shiro quickly began to run. On the way, he saw Sand Village ninjas emerging from their hiding spots, battling with the Leaf ninjas rushing to respond.

Shiro knew he couldn't be careless. One mistake could mean death, so he hurriedly activated his Sharingan!

*Ding dong! Fire Style: Fireball Jutsu identified!* 

*Ding dong! Wind Blade Jutsu identified!*

*Ding dong! Host has learned two low-level ninjutsu. Would you like to combine them? (100% success rate, 0% failure rate)*

Combine! Combine! Combine!

With a 100% success rate, Shiro had no reason to refuse!

*Ding dong! Combination successful! You have learned Fire Style: Phoenix Flower Jutsu!* 

*Ding dong! Two remaining combination attempts available.*

"Haha! Looks like there's still a loose end. Let me send you on your way!" 

With a laugh, a Sand ninja jumped out, brandishing a kunai aimed directly at Shiro's neck!

Instantly, Shiro's Sharingan spun into action, taking in every move of the Sand ninja.

Shiro instinctively dodged to the side while his hands rapidly formed seals.

"Fire Style: Phoenix Flower Jutsu!"

With a shout that screamed "edgy," Shiro felt a burning sensation rise from his lungs.

With a powerful exhale, a massive fireball burst forth, splitting into countless smaller flames, flying out like a soaring phoenix.

"Sharingan... combined jutsu... who is this kid?!"

The Sand ninja's eyes filled with fear, and he didn't even have time to call for help before the flaming phoenixes claimed his life!

Shiro was ecstatic. If combining two low-level ninjutsu could create something this powerful, what about higher-level jutsu?

He couldn't help but let his imagination run wild!

What could combining the Rasengan and Chidori create?

What about Planetary Devastation and Amaterasu?

And if you combined the Reverse Harem Jutsu with the Moon Reader... it would definitely be the ultimate forbidden technique!

For a moment, Shiro bent over with laughter, his eyes forming crescent shapes.

"Right! The Third Hokage! All the advanced jutsu are there!"
