Chapter 170: The Emergence of Space-Time
"That's the Fourth Hokage's jutsu without hand signs!"
"Hahaha! Kid, you haven't mastered the Fourth Hokage's jutsu without hand signs yet!"
"Prepare to die!"
As the fierce battle commenced, Koshino merely used Tsuchigumo as a stepping stone, while his true target was Raiga, who posed a significant threat to Guy, Genma Shiranui, and Ebisu.
Unexpectedly, just as Koshino's surprise attack on Tsuchigumo was about to succeed, Jinin Akebino and Fuguki Suikazan launched their attacks, completely disrupting Koshino's battle rhythm!
Some might ask, what use is battle rhythm? Can you eat it?
In reality, one must never underestimate the importance of battle rhythm. It is often the key to controlling the direction of a high-level battle, something easily overlooked.
Had Jinin and Fuguki not disrupted Koshino's rhythm, not only would Raiga, Koshino's true target, have been in danger, but even Tsuchigumo, used as a stepping stone, would have been severely injured, further weakening the Seven Ninja Swordsmen of the Mist!
Of course, ninja confrontations are ever-changing, so those who can truly grasp the rhythm of battle are often high-level ninjas facing lower-level ones.
Koshino's battle rhythm being shattered by the Seven Ninja Swordsmen is quite normal here.
Moreover, the disruption of battle rhythm was just a minor surprise, within Koshino's expectations.
The real unexpected event occurred during the confrontation with Fuguki Suikazan!
In that moment, Fuguki Suikazan attacked, wielding the great sword-Samehada, aiming to absorb Koshino's chakra. Who would have thought that Koshino's left hand, gathering a Rasengan, would catch Fuguki's attention? During the Third Great Ninja War, Fuguki had witnessed the Fourth Hokage using the Rasengan in battle!
The Fourth Hokage was an undeniable presence during the Third Great Ninja War!
Although Koshino frequently used the Fourth Hokage's secret techniques, such as Wind Perception, Wind Acceleration, and Wind Body Flicker, not everyone could recognize them as the Fourth Hokage's techniques!
Only those very familiar with the Fourth Hokage would know of these secret techniques!
However, the Rasengan was different! Fuguki had personally seen the Fourth Hokage's figure transform into a golden light, using the Body Flicker Technique to harvest the lives of Mist ninjas with the Rasengan!
So, when Koshino's left hand formed the Rasengan, Fuguki was extremely cautious, fearing he might fall victim to the Fourth Hokage's jutsu without hand signs and be instantly killed by Koshino!
Who would have thought, the next second, as Koshino's left hand formed the Rasengan, the blue light it emitted flew in the direction Koshino threw it, almost scaring Fuguki to death!
After all, in Fuguki's memory, the Fourth Hokage had never thrown the Rasengan; it was always used at point-blank range to kill!
Seeing Koshino's Rasengan being thrown, Fuguki's heart sank, preparing himself for a hit!
But who could have imagined, the Rasengan Koshino threw flew out with a "whoosh" and then with another "whoosh" it disappeared!
Laughter echoed through the dense forest almost the instant Koshino's thrown Rasengan vanished, resonating in Fuguki's direction.
In an instant, the situation Koshino faced took a sharp turn for the worse!
When the Rasengan Koshino threw disappeared, Fuguki was full of glee, laughing wildly as he swung down the great sword Samehada, ready to devour all of Koshino's chakra for a hearty meal!
In contrast, Koshino, seeing the Rasengan vanish, felt his heart sink to the bottom!
He could even foresee the dire situation he would face once his chakra was absorbed by the great sword Samehada!
But!
Just as Fuguki confidently swung the great sword Samehada towards Koshino's shoulder!
"Boom!"
Suddenly!
Koshino suddenly felt a wave of weakness, and immediately noticed that a significant portion of his chakra had vanished!
Moreover, just as Koshino's chakra inexplicably disappeared, the previously vanished Rasengan struck Fuguki with full force!
The next second, Koshino watched as Fuguki's massive figure was sent flying backward by the power of the Rasengan!
With the situation once again turning in his favor, Koshino noticed the reappearance of the vanished Rasengan, and a look of astonishment crossed his eyes!
"What just happened?"
"My thrown Rasengan disappeared, didn't it? How did it suddenly reappear?"
"Could it be..."
"Could it be like the Shadow Stitching Jutsu or the Shadow Clone Jutsu I mastered? After my mental energy broke through its limits, did the Rasengan undergo a mutation?"
As he pondered this, Fuguki's large figure crashed heavily to the ground with a "thud."
As for Koshino, with his brows slightly furrowed, he recalled the scene where the Rasengan suddenly disappeared and then reappeared out of thin air. A familiar image flashed in his mind!
That image was a scene from the Naruto movie!
Before crossing over, Koshino was a Naruto fan and never missed an episode of the original series.
Especially after Naruto concluded, with a deep affection for the series, Koshino would watch any new Naruto movie multiple times, regardless of its quality, and find ways to store it as a keepsake.
Shortly before Koshino crossed over, the latest Naruto movie, Boruto: Naruto the Movie, was released. The protagonist, Boruto Uzumaki, is the son of the original protagonist, Uzumaki Naruto, and now the grandson of Koshino's mentor, the Fourth Hokage!
No mistake, every detail was seen!
He remembered that when Boruto Uzumaki was training with Sasuke Uchiha, Boruto used a Rasengan that, although much smaller than a real Rasengan, had a unique feature. When thrown, it could suddenly disappear in its trajectory, almost like it was invisible, and then reappear out of nowhere.
It was with this new feature of Boruto's Rasengan that the boss in Boruto was defeated by the combined efforts of Boruto Uzumaki and Uzumaki Naruto.
As Koshino recalled the scene of Boruto using the Rasengan in Boruto: Naruto the Movie, he naturally connected it to the Rasengan he had just used!
Immediately, a look of realization appeared in Koshino's eyes, and his previously furrowed brows relaxed!
"When I threw the Rasengan just now, it was just like Boruto's Rasengan, disappearing first and then reappearing to hit"
"And I vaguely remember that when the Rasengan reappeared, some of my chakra inexplicably vanished!"
"Could it be that after my mental energy broke through its limits, the Rasengan's mutation is this ability to disappear out of thin air?"
"Could this special ability of the Rasengan to vanish be..."
"Could it be some kind of space-time ninjutsu?"
The term "space-time ninjutsu" flashed in his mind, and Koshino felt a "boom" in his head, leaving him stunned.
At that moment, it wasn't that Koshino was overreacting, but the allure of space-time ninjutsu was too great!
Take Koshino's mentor, the Fourth Hokage, for example. Would he have achieved his current accomplishments without mastering a branch of space-time ninjutsu, namely the Flying Thunder God Technique?
And what about Kamui, the technique jointly mastered by Kakashi and Obito Uchiha? What terrifying power does it contain?
So, just the term "space-time ninjutsu" was enough to leave Koshino feeling shocked and filled with endless joy!
However, whether the Rasengan's disappearance truly marked the emergence of space-time ninjutsu, Koshino couldn't be entirely sure. But as Koshino speculated that this new feature of the Rasengan might indeed be a branch of space-time ninjutsu, the previously tense Koshino, hidden behind his Anbu mask, allowed a faint smile to appear on his face!
"Who cares if it's space-time ninjutsu or not!"
