Boom!
A sudden rumble echoed through Yun Xi's mind...
His body also began to change.
When he had strengthened his body earlier, nothing unusual had happened. But after he activated his Three-Tomoe Sharingan,
a wave of flame-like energy burst from within him.
"What is this power?"
Yun Xi was at a loss. This was the first time he had encountered anything like it.
He thought back to how the Sharingan worked in the original story, but there had never been anything like this.
"Could it be..."
A bold idea suddenly came to Yun Xi.
This wasn't the first time he had felt a strange flame-like energy appear inside his body.
But the last time it happened was after he had eaten the Flame-Flame Fruit.
Until now, Yun Xi hadn't thought to connect the Sharingan and the Flame-Flame Fruit.
But judging by what was happening now,
the two seemed to be connected...
After all, one came from One Piece,
while the other belonged to Naruto.
Combining them might produce some strange chemical reaction.
With that thought, Yun Xi didn't hesitate.
He kept his Sharingan active while continuously stirring the power of the Flame-Flame Fruit within him.
Sure enough,
the result was completely different from what Yun Xi had expected.
With the Sharingan activated, he could clearly feel the flames inside him growing stronger. At the same time, these two powers, which originally belonged to entirely different systems, began to converge when he deliberately tried to merge them!
"So the Devil Fruit and the Sharingan can have this kind of chemical reaction?"
When Yun Xi first obtained the Flame-Flame Fruit, he had only intended to keep it as a trump card.
But now, after seeing this,
a different idea began to take shape in his mind...
In One Piece, the Flame-Flame Fruit was a Logia Devil Fruit, one of the most powerful types of Devil Fruit.
Eating one granted the user the ability to control a natural element.
However, the power of a Devil Fruit wasn't fixed. It could be used in all sorts of ways.
In practice, how far a Devil Fruit's power could be taken depended on the user's own strength.
Powerful figures like Kizaru and Akainu, high-ranking officers at Marine Headquarters, also wielded Logia Devil Fruits.
The powers their Devil Fruits granted them were even capable of destroying the world.
But after eating the Flame-Flame Fruit, Yun Xi could only use it to enhance the power of his fire-based ninjutsu.
The difference between them was so vast that Yun Xi could hardly believe it.
Still, Yun Xi wasn't bothered by this.
He knew that
the power of any Devil Fruit had to be trained before it could be fully mastered.
At its core, the Flame-Flame Fruit's abilities were fairly simple.
It let the user turn any part of their body into fire and freely shape the flames they produced, creating things like nets of fire or attacks such as Fire Fist.
This was similar to how fire-based ninjutsu worked in the Naruto world, but the fighting styles were different.
Fire Release Ninjutsu in the Naruto world was mostly used for long-range attacks, relying on wide-area attacks to eliminate enemies.
The Flame-Flame Fruit, on the other hand, was better suited to close combat.
Yun Xi had originally planned to learn the Eight Inner Gates and pair them with the Flame-Flame Fruit.
But...
Now that he knew the Sharingan and the Flame-Flame Fruit could produce a strange chemical reaction,
he had to reconsider his fighting style...
"If I can master the Eight Inner Gates, combining them with the powerful Flame-Flame Fruit and its immunity to close-range attacks would still be a good choice..."
"But..."
"The combination of the Sharingan and the Flame-Flame Fruit is..."
For a moment, Yun Xi was torn.
Ultimately, the reason he was so conflicted was that Fire Release Ninjutsu in the Naruto world was simply too weak.
According to the Naruto setting, Fire Release was the most powerful offensive technique among the five elemental natures...
But...
In Yun Xi's memories,
there didn't seem to be any particularly powerful Fire Release techniques...
Take Fire Style: Blast Wave Wild Dance, for example.
It was the first technique Obito used after his mask was broken.
It was also a Fire Release technique used in conjunction with the Mangekyō Sharingan. By using the Mangekyō Sharingan's Kamui to create and release a spiraling vortex, the user could then breathe fire into the space, unleashing a wide-area attack.
Uchiha Obito had even said outright that it was the most powerful Fire Release technique in the Uchiha Clan.
Yet a technique praised so highly
was only ranked B-rank in the official Naruto setting.
How could Yun Xi accept relying on Fire Release Ninjutsu from the Naruto world as his main means of attack?
And yet...
After seeing how the power of the Flame-Flame Fruit could merge with the power of the Sharingan, Yun Xi didn't want to give up on it just like that...
"I'll give it a try..."
After thinking it over for a long while, Yun Xi still hadn't made up his mind.
He glanced at the dark night around him, then decided to find somewhere to test just how powerful the fused power of the Sharingan and the Flame-Flame Fruit really was.
Once he had decided, Yun Xi headed out.
Ten minutes later, he arrived at an open clearing deep in the mountains behind Konoha, near the Forest of Death.
After making sure there were no strangers nearby, Yun Xi immediately prepared to experiment!
"Sharingan!"
"Activate!"
"Now to draw on the power of the Flame-Flame Fruit..."
Yun Xi activated his Sharingan first, then stirred the power of the Flame-Flame Fruit within him.
In an instant, the same thing as before happened again.
And this time, because Yun Xi released the power of both at once,
the flames were even more intense than before.
The intense heat even made his skin turn slightly red...
"I need to hurry. I can't maintain this state for long..."
Realizing that his body still couldn't withstand this power for very long, Yun Xi didn't waste any more time. After getting his body into the best condition he could,
he immediately gathered his chakra and infused it with the fiery energy!
Then Yun Xi formed Hand Seals...
"Fire Style!"
"Great Fireball Technique!"
The moment Yun Xi unleashed the Great Fireball Technique, the once pitch-black surroundings lit up brilliantly!
But the Great Fireball Technique Yun Xi had released no longer looked anything like it had before...
It would be more accurate to say that what Yun Xi had unleashed wasn't a great fireball at all.
It was a little sun...
