Uchiha Kei strolled leisurely towards Black Zetsu.
Ten minutes ago, he had just completed Space-Time Mission and had only just appeared in the Twilight Ninja Village when he was informed by White Bone Momotao that the Fourth Shinobi World War had begun.
Ignoring the incessant system notifications ringing in his mind, Uchiha Kei rushed to the battlefield without stopping.
Fortunately, he arrived just in time to strike Black Zetsu.
"You... Uchiha Kei! Weren't you missing?"
Black Zetsu stared in horror at Uchiha Kei before him.
If we're talking about the Shinobi World, the one he's most worried about isn't the God of Shinobi Senju Hashirama, nor the Shinobi World dancer Uchiha Madara.
Instead, it was the person standing before him, Uchiha Kei!
A being whose rise to power was even faster than that of Senju Hashirama!
The horrific destruction of the Yang Organization six years ago was his doing.
Uchiha Itachi's rise to become the Fifth Hokage was his doing.
The sudden emergence of the Twilight Ninja Village was his doing.
He single-handedly created the current Shinobi World order!
This is the kind of person who remains an enigma; no one knows the true extent of his strength.
To Black Zetsu, this enigmatic existence was an unstable factor.
Therefore, Black Zetsu chose to start the Fourth Shinobi World War during the period when he was missing.
The purpose was to avoid Uchiha Kei.
Unfortunately, just when success was within reach, this guy appeared!
"Even if you don't disappear, you still have to dare to come out."
Uchiha Kei chuckled softly.
The reason he chose to start the Space-Time Mission at this time was partly because the pressure from the Otsutsuki Clan was too great, and he needed stronger power.
On the other hand, they also wanted the plot to move forward faster.
Only after the Fourth Shinobi World War ends can the Shinobi World return to a period of peace.
He and his Twilight Ninja Village need more time to prepare for the invasion of the Otsutsuki Clan.
Black Zetsu was initially taken aback, then his expression turned ferocious.
"You did this on purpose! Uchiha Kei, you bastard! Once Mother breaks free from her seal, you'll suffer a terrible death!"
Uchiha Kei shrugged indifferently.
Kaguya, now that she's broken free of her seal, attack me?
Without this Space-Time Mission, it would have been a foregone conclusion.
But what about now?
Even Kaguya's seal was orchestrated by him; it would be a miracle if he were to intervene.
However, he didn't see Black Zetsu's birth when he sealed Kaguya, which puzzled him.
But if it wasn't Black Zetsu created by Kaguya, then who was it?
After sorting out his chaotic thoughts, Uchiha Kei turned his gaze to the two people standing dumbfounded not far away.
"Teacher, you've arrived."
Suppressing his excitement, Uchiha Izuna quickly walked up to Uchiha Kei.
"Hmm, well done, your swordsmanship has improved rapidly."
Uchiha Kei patted Uchiha Izuna on the shoulder with a sense of relief.
He sensed from that last strike that Uchiha Izuna's swordsmanship had reached a new level, no longer confined to his own style, but beginning to communicate with the heavens and earth.
This is the effect after mastering swordsmanship.
"The teacher taught well."
Uchiha Izuna scratched his head humbly.
"Your body is perfectly suited to the sword. Keep practicing your swordsmanship diligently. Your teacher is waiting for the day you surpass me."
Seeing Uchiha Izuna's body, which was faintly radiating Blade Intent, Uchiha Kei was very happy.
From the day Uchiha Izuna died in Konoha, he began his research using Uhijini's creative power.
After several years of painstaking exploration, Uchiha Kei finally created the most suitable body for Uchiha Izuna. Three months ago, together with Orochimaru, they used the Impure World Reincarnation to extract Uchiha Izuna's soul and place it in this body.
"Surpass the teacher? How is that possible?"
Uchiha Izuna knew his teacher's swordsmanship was an insurmountable mountain.
"That day will come eventually, keep going."
With a smile on his face, Uchiha Kei turned his gaze to the other two.
"Hashirama, it's been a long time."
With just one sentence, the once-mighty God of Shinobi's eyes instantly welled up with tears.
"Teacher...!"
In short, it was earth-shattering.
Both the Allied Shinobi Forces, who were preparing to withdraw, and the Five Kage, who arrived late, were all gaping in shock.
"Ding! Shock received from Uchiha Itachi. Shock Value +999."
"Ding! Shock received from Mei Terumi. Shock Value +999."
"Ding! Shock received from Ōnoki. Shock Value +999."
"Ding! Shock received from Gaara. Shock Value +99."
"Bite..."
A series of Shock Value alerts instantly rang in Uchiha Kei's mind.
Seeing the rapidly increasing Shock Value, Uchiha Kei was quite happy.
You can never have too much Shock Value!
Senju Hashirama!
God of Shinobi!
A legendary existence!
At this moment, he's actually acting like a child, calling Twilight Shadow "Teacher" with red eyes???
What's going on?
The two were from completely different eras, so how could they possibly have any connection?
Not to mention that Uchiha Kei was Senju Hashirama's teacher.
At that moment, almost everyone who heard it felt their head buzzing.
Even everything around me started to feel unreal.
"You're such a grown-up, yet you still cry so easily."
Uchiha Kei walked over and stroked his hair.
"Teacher!"
Feeling Uchiha Kei's genuine warmth and presence, Hashirama finally believed that what he was seeing was real, and tears streamed down his face uncontrollably.
"Teacher, you're finally back! I almost couldn't hold on anymore these past few years."
A look of heartache flashed in Uchiha Kei's eyes.
He knew that the years Hashirama was referring to were the years after the founding of Konoha and his subsequent enmity with Madara.
Given Hashirama's gentle nature, it was truly remarkable that he persevered and even managed to kill Madara in the end.
"Teacher, you don't know, back then Madara scolded me for being indecisive, and Tobirama always scolded me for being soft-hearted, they both drove me to kill..."
Hashirama's vision was blurred by tears, and in a daze, he seemed to return to the days of the past.
Back then, the teachers were still instructing them, and Madara and Tobirama were always bossing him around. Whenever he tried to resist, the two of them would gang up on him and beat him up.
As for Uchiha Izuna...
This guy doesn't care about anything except his knife.
After that, he would run to the teacher to complain, and then watch the teacher berate Madara and Hashirama.
Hiding behind his teacher, watching Madara and Hashirama's angry but speechless expressions, was the most enjoyable time for him.
But after the teacher left, everything changed.
No one will stand up for him anymore, no matter how small his grievances are, so he can only try his best to be strong.
In the end, he was still just that slightly silly and naive boy from back then.
"Yeah?"
Uchiha Kei narrowed his eyes, giving Uchiha Madara a dangerous look.
Ban subconsciously shuddered.
It wasn't that he was afraid of the teacher, but rather that he was suddenly overwhelmed by memories of his past.
In the past, this would have been followed by a torrent of angry abuse, right?
"Yes! Especially Madara! He..."
Hashirama instantly thought of Tobirama, whose soul had been Tobirama, and a pained expression appeared on his face.
"Tobirama... Madara killed Tobirama, even his soul..."
Uchiha Kei was taken aback.
Tobirama...
Is it completely dead?
Even the soul has disappeared?
Tobirama's body is ready, too.
The Tobirama, the Hashirama, and...
Spotted!
"Whoosh!"
Uchiha Kei's figure vanished from his spot in an instant, and the next moment, he appeared directly in front of Madara.
"Teacher..."
Ban swallowed hard and instinctively took a step back.
Of the four, he was the most strong-willed, which made him the most likely to be punished by the teacher's whip.
That kind of tremor that comes from the soul is really not very pleasant.
"Madara, how strong is the Ten-Tails Jinchuriki?"
Uchiha Kei squinted his eyes and asked with a chuckle.
"Very strong, extremely strong!"
When the topic turned to the Ten-Tails Jinchuriki, Madara instantly thought of the power he currently possessed, and his confidence returned.
Yes.
He now possesses power comparable to that of a god!
What can the teacher do about it?
"Oh? Heh, it seems you think you already possess power surpassing mine."
Uchiha Kei noticed the change in his expression, but instead of getting angry, he smiled even more brightly.
Madara straightened his body, and surging Chakra flowed rapidly within him, a terrifying aura spreading out from him.
"Teacher, even you don't possess such power!"
Uchiha Kei nodded truthfully. "That's right, I have never possessed the power of the Ten-Tails Jinchuriki."
Upon hearing Uchiha Kei's admission, Madara became even more excited. "Sensei, could such power bring lasting peace to the Shinobi World?"
"Able."
Uchiha Kei nodded seriously.
If it weren't for the threat from the Otsutsuki Clan, the Ten-Tails would indeed have been able to deter some ambitious figures in the Shinobi World.
"If that's the case, then my path is the right one, isn't it?"
Madara looked at Uchiha Kei, wanting to hear confirmation from him.
Pity.
Uchiha Kei gently shook his head. "Whether it's right or wrong is no longer important."
Ban's expression froze.
"I'm asking you, where did Tobirama go?"
Uchiha Kei looked at his face and asked, word by word.
Tobirama...
A flicker of pleasure flashed deep in Ban's eyes, then vanished just as quickly.
He blocked my way.
"Hmm, so what? Where did Tobirama go?"
Uchiha Kei's smile grew wider and wider, his eyes narrowing into slits.
Naruto Sasuke, who knew him well, had already started looking for a place to hide.
Scene...
I'm so angry! I've never been angrier before!
He... is dead.
Madara avoided Uchiha Kei's gaze and looked to the side.
"Dead? Heh."
Uchiha Kei into laughter, laughing so hard he bent over.
Ban watched quietly, without saying anything more.
"Do you remember what I told you when I left?"
After a long while, Uchiha Kei finally stopped smiling and casually wiped away the tears that had welled up in his eyes.
Ban looked bewildered.
So many years have passed, he can no longer remember many things from back then.
"I've said it before, you can do whatever you want, after all, peace is such a vague and elusive thing."
Uchiha Kei lowered his head slightly, his long hair obscuring his expression.
"But no matter what, you can't..."
Uchiha Kei suddenly raised his head, his expression cold and filled with killing intent.
Ban took a step back in shock.
He saw that Uchiha Kei's eyes had completely changed at that moment.
One, with purple circles covering its pupil.
One, radiating a crystal-clear blue, like an endless sea.
He recognized the Rinnegan, but what about the other one?
"Fratricide!"
Uchiha Kei's figure flashed, and an extremely terrifying aura began to emanate from his body.
"Smack!"
A loud slap rang out, and Ban's cheek immediately became red and swollen, causing his body to involuntarily rush towards the rocky hillside beside him.
"Boom!"
A tremendous sound rang out, and Uchiha Kei, like Madara, remained silently suspended in mid-air.
Two eyes, each gleaming with a different, dangerous light.
