If it were any other student facing this C-Rank Jutsu, he would most likely be killed in a matter of seconds!
But that is not the case with Naito, who unhesitatingly retreated.
However, his speed was not comparable to the speed of the fireball.
Just as the fireball was about to hit Naito, a white halo covered the Kunai in his hand, AND he fiercely slashed the fireball!
"Slash!!!"
Crack!
The white halo suddenly erupted at that moment, but under Naito's control, the shock power did not collide head-on with the large fireball, but instead split it in half.
At that moment, the large fireball basically reached its limit distance, and under Naito's vertical slash…it split in half!
The flames passed by the sides, without colliding with Naito.
Seeing this scene, Naito did not show any joy, on the contrary, he became more and more calm.
He still couldn't destroy a C-Rank Jutsu head-on, so he could only deal with them intelligently... but, he wasn't far away from being able to directly destroy C-Rank Jutsus.
However, the large fireball was very close to him.
The students didn't see Naito's actions, so they had very horrified expressions.
"He is dead..."
"My God, this is terrible, they killed him"
All the students saw was Naito being consumed by the big fireball.
They all panicked.
On the other hand, Kushina couldn't even contain herself and was about to rush into the ring, tears even appearing in her eyes, as she internally blamed herself.
Why did she let Naito fight Uchiha Izumi, why didn't she stop Naito?
At this moment, the only one who could stop all this was Nakamoto, who was gritting his teeth.
It looked like Naito was dead.
Even Uchiha Izumi thought that was also the case, he thought that Naito had turned to ashes, his face was a little pale, but with a hint of coldness.
But the next moment, his expression froze.
A look of horror and disbelief appeared in his eyes.
For, from within the gradually dissipating flames, a figure became clearer and clearer and finally rushed toward him.
The person who rushed out from the flames was none other than Naito.
"Impossible!!!"
How could Naito resist the fireball?
Uchiha Izumi felt that it was unbelievable. Seeing Naito come out of the flames, in panic, he threw a punch in Naito's direction.
Resisting the large fireball, Naito must have also exhausted all his chakra, staying standing only by his willpower.
Thinking about this, Uchiha Izumi showed a trace of confidence in his eyes.
However, in front of him, Naito looked at him coldly and used his fist to collide with Izumi's.
A white halo surrounded Naito's fist.
The next moment, Naito's fist and Izumi's fist collided, however, Naito's fist stopped a few centimeters away from Izumi's fist.
Crack!!!
Again, that strange sound was heard again, and white cracks spread through the air, it seemed like space itself was fragmenting.
Izumi's arm was also emitting crackling sounds, her body couldn't withstand such power, AND her arm abruptly broke off!
The shockwave spread out, crashing into his entire body and throwing him backwards.
Thud!
The shockwave threw Uchiha Izumi into the distance, his eyes still wearing an expression of shock and disbelief, and he suddenly sculpted a mouthful of blood due to his wounds, immediately fainting from the pain.
The surroundings were plunged into silence
At that moment, Naito extinguished the burning flames on his clothes, and at the same time, he gently removed his burnt locks of hair and casually tossed them away.
After the silence, there was finally an uproar.
"That's amazing!!!"
"Oh my God! This can't be true, can it?"
"How did he escape from that big fireball?"
Suddenly, everyone felt like they were dreaming.
All the students couldn't help but stare at Naito in shock and disbelief.
They couldn't believe it, Naito... Did he really defeat Uchiha Izumi?
In other words, Naito was no longer a failure, but had jumped up to become a genius second only to Minato.
That's amazing!
In the crowd, Kushina looked at the scene blankly, a faint tear glistening in the corner of her eyes.
She hadn't even reacted until now.
Naito ignored the shocked students and instead looked at Kushina and apologized while wiping the burnt skin on his arm, "Sorry, I still suffered an injury."
"..."
Kushina pursed her small mouth and looked at Naito blankly and muttered under her breath, "Idiot!"
Kushina wiped the tears from her eyes and then restored her face resumed her lively gaze.
In the ring, Nakamoto was stunned and then looked at Naito in horror and muttered, "You, you..."
Naito calmly looked at Nakamoto and said lightly, "Looks like I won, didn't I!"
Nakamoto was stunned and couldn't help but rub his eyes.
It never crossed his mind that Naito would win, and that the one who was seriously injured in the end would be Uchiha Izumi!
If it had been Naito who had been injured, it wouldn't have mattered, but with Uchiha Izumi injured, he, the class teacher, had to bear a lot of pressure, and the responsibility for what happened would fall on him.
His expression was extremely ugly, but in the end he could only bitterly announce Naito's victory.
However, noticing Uchiha Izumi injured in the distance, Nakamoto approached Naito and said in a low voice, "Doing what you did to an Uchiha, you should watch your back, Naito."
"I think this is none of your business, Sensei," Naito replied briefly and then exited the ring.
All the students looked at Naito in amazement for a long time.
He even caught Minato's attention, starting to be more interested in him.
After that sparring test, Naito became the center of attention of the entire Ninja Academy.
Many people were surprised by the power Naito was using.
Naito explained that it was a Kekkei Genkai, which used vibrations.
It was a perfect explanation.
After all, in this world, there is not much chance to obtain a Kekkei Genkai like the eyes of the Uchiha or Hyuga Clan, some other Kekkei Genkai include mixing a type of elemental chakra, creating the element wood or ice as a result.
This explanation surprised everyone, but after a while, they began to accept it.
...
Konoha, in an open space.
The sky was getting dark, but Naito continued to train.
This was the first time he defeated someone, and he was proud for that, but Naito knew that trouble would come later, so he put more effort into training, his goal was to further improve the power of his Kekkei Genkai Temblor.
"Four hundred and fifty one, four hundred and fifty two... four hundred and ninety nine, five hundred!"
"Whew!"
When he reached his predetermined number, Naito stretched his arms almost stiff and then stood up.
When he trained outside, he basically didn't do extreme exercises.
Only at home did he try to squeeze out all his strength.
Although not much crime happened in Konoha, Naito learned at a very young age to take care of himself.
With his body drenched in sweat, Naito headed home, musing on the way, "At this rate, I'm going to have to start using weights."
It had been almost a month since he ate the devil fruit and obtained the Kekkei Genkai Temblor.
In this month, Naito gave up Ninjutsu and chakra training, and instead focused on training his body.
