"Could this really happen when the power of the Flame-Flame Fruit and the Sharingan are fused?"
After the Great Fireball Yun Xi had casually released exploded in the distance, he was stunned.
It was hard to call the effect of the Fire Style: Great Fireball Technique he'd released earlier a fireball.
It was more like an orange-red energy blast!
In the stillness of the night, this Great Fireball Yun Xi had released was unlike any other ninjutsu he'd used before.
Ordinary Fire Release Ninjutsu used chakra as their main energy source, which was then transformed into a fireball to attack the enemy.
But what Yun Xi had released was completely different...
The fireball was dense, and a faint reddish-white glow surrounded it.
And after it struck its target, it didn't simply disappear. Instead, it exploded!
"That's ridiculous..."
Yun Xi had now returned to the spot where he'd launched his earlier attack. Looking at the small, pitch-black crater before him, he really hadn't expected the two powers to produce such an effect when combined.
The Great Fireball he'd released was already as powerful as an ordinary B-rank Fire Style Ninjutsu!
"Is this the power of the Flame-Flame Fruit?"
For a moment, Yun Xi thought of the Flame-Flame Fruit.
But...
When he saw the faint flames still flickering at the site, he immediately dismissed the idea.
The few remaining flames carried only the power of chakra. There was no energy from the Flame-Flame Fruit in them.
In other words...
The reason he'd released such powerful flames was the chakra within his own body...
"I understand!"
After thinking it over for a few minutes, a look of realization came over Yun Xi's face.
The moment he released the Great Fireball Technique, the Flame-Flame Fruit's energy hadn't directly merged with his chakra.
Only after Yun Xi had finished forming the Hand Seals did he feel a mysterious energy within him suddenly flow into the Great Fireball.
Then, when Yun Xi released it...
The different energies fused together, producing that Great Fireball Technique...
"So this should be the result of the Flame-Flame Fruit, the Sharingan, and chakra all combining..."
Thinking back to the Phoenix Sage Fire Technique he'd used earlier, Yun Xi finally figured out why this had happened...
"I'll try it again!"
To confirm his theory, Yun Xi decided to experiment once more.
This time, though, he didn't plan to activate the Sharingan. He would only draw on the Flame-Flame Fruit's energy first.
"Fire Style: Great Fireball Technique!"
Just like before, Yun Xi formed the Hand Seals the same way, injecting the Flame-Flame Fruit's energy into his chakra before he finished.
The only difference was that this time, he didn't activate the Sharingan!
Sure enough...
The result was just as Yun Xi had expected.
The Great Fireball Technique he released this time was different from the one before...
The earlier Great Fireball had been tremendously powerful, with a dense, energy-packed appearance. It had even exploded after striking its target.
But this time...
It was only a little different from a normal Great Fireball Technique.
It was definitely more powerful.
But not nearly as outrageous as before...
"It seems the main reason I could release that earlier Great Fireball was that the Sharingan and the Flame-Flame Fruit's power can fuse. That must be why it turned out like that..."
To see if he was right, Yun Xi began another experiment.
This time, he activated the Sharingan, but didn't use the Flame-Flame Fruit's power when he released the ninjutsu...
If...
The Great Fireball Technique turned out differently again...
With the fire-based energy boosting it, this Great Fireball Technique was only slightly larger than one released under normal conditions, and its power had increased a little as well.
In this form, the Great Fireball Technique was closer to the fire-based ninjutsu Uchiha Yu had released.
"I had no idea there'd be such a big difference between these three states."
To make sure he hadn't misunderstood, Yun Xi experimented more than a dozen times on the spot.
In the end, he came to the following conclusions.
Without activating the Sharingan or using the Flame-Flame Fruit's power, the Great Fireball Technique Yun Xi released with the system's Fire Release Ninjutsu boost had an extremely high flame temperature and consumed an ordinary amount of chakra.
When he released Fire Style Ninjutsu with the Sharingan activated, the flames took on an overall orange-red hue and covered a wider area, but they consumed more chakra as well.
The third state involved using the Flame-Flame Fruit's power to release Fire Style Ninjutsu. In this state, all the Fire Style Ninjutsu Yun Xi used were more powerful than normal.
The flames also took on a liquefied appearance, greatly increasing their speed!
Of course, the most powerful state was when he combined all three sources of power.
Any Fire Style Ninjutsu released in this state glowed faintly.
The flames were dazzling.
Their power, temperature, and energy density all came close to the highest possible levels of heat...
Yun Xi even noticed that the places struck by these unique flames during his experiments had turned crystalline...
Flames hot enough to melt sand...
Once he realized that, Yun Xi was shocked...
At least, he'd never seen this kind of power in the original story!
In traditional ninjutsu matchups, aside from Water Release, Earth Release was also highly effective against Fire Style.
But...
Yun Xi felt that ordinary Earth Release Ninjutsu probably couldn't stop him under these circumstances...
"I really hit the jackpot this time..."
After figuring out all three states of power within himself, Yun Xi stopped experimenting.
He'd originally thought he'd only gotten a Three-Tomoe Sharingan.
He hadn't expected such an incredible reward today.
"I've only been testing with C-rank Fire Style Ninjutsu. What if I used B-rank Fire Style Ninjutsu instead?"
On his way home, an idea suddenly crossed Yun Xi's mind...
"Train! Learn stronger Fire Style!"
At last, Yun Xi no longer looked down on Fire Style Ninjutsu just because it couldn't kill anyone!
"Ding! Congratulations, host, on unlocking the hidden power of Fire Style. Reward: Fire Style Ninjutsu power increased by 10%..."
After he got home, Yun Xi didn't expect the system to surprise him again...
A 10% increase in Fire Style Ninjutsu power...
It might have seemed like a tiny reward...
But it really wasn't!
"The damn system finally came through!"
Feeling another trace of fiery energy inside him, Yun Xi finally smiled with delight...
