"Beautiful, don't you think...? Zetsu..." As Kazuki controlled Rin's body, he said to Zetsu with a smile. "Thanks to my modifications, this body now possesses blood and organs as real as those of any human being."
"It is the result of Takigakure's secret technique..."
Black Zetsu silently watched Obito.
"Why, why..." Uchiha Rin asked hoarsely: "You..."
However, Uchiha Setsuna did not respond and just twisted the sword without hesitation, completely destroying Rin's heart.
It all happened in an instant.
Uchiha Obito, who lived in paradise until a moment ago, suddenly descended into hell. With his eyes wide open, he saw the life of his beloved fade away, turning into blood that dyed the earth crimson.
"For the Uchiha clan's revenge... I have no choice but to kill you, child." Uchiha Setsuna looked at the dying Rin and, with a regretful expression, slowly withdrew the katana from her chest. "I really hope Uchiha Obito can live. If possible, I even hope he can see this scene."
"I wouldn't mind giving my life... if that would awaken the most powerful Mangekyō."
"As long as I can defeat Uchiha Kazuki... as long as I can destroy the Hokage line in Konoha..."
As his words echoed through the air, the tomoe in Obito's eyes began to spin violently. A sharp and complex pattern emerged in his eyes in an instant.
And then, it happened.
A large amount of blood gushed out of Obito's eyes, and in the blink of an eye, Uchiha Setsuna was torn apart by a terrifying storm of distorted space. His body was torn apart, his limbs flying in all directions.
That day... Obito's double Kamui was born.
In the next split second, Obito used his newly acquired power to instantly rush to Rin's side. His hands trembled, his entire body convulsed as if he were on the verge of collapse.
"What do I do?"
"What am I supposed to do?"
With her last trace of consciousness, Rin, seeing that Obito had appeared in front of her, smiled.
It was like the last glimmer of a candle about to go out.
With great effort, she reached up and pulled out a diary from her chest. It was covered in dirt and blood. The moment she pulled it out, she coughed up a mouthful of blood, further staining the notebook red.
"I'm sorry... I'm so sorry, Obito..." She looked at the diary, now soaked in her own blood, with an expression of deep guilt. "Being able to see you one last time... it's the best thing that could have happened to me..."
"Rin, Rin, don't move!" Obito was on the verge of despair.
But Rin simply waved her hand at him, motioning for him to come closer.
Obito, without hesitation, lowered his head.
Rin's bloody lips approached his...
But the kiss never happened.
Obito watched helplessly as Rin's Sharingan evolved from two tomoe to three. However, what shook him most was not the growing power in her pupils, but the mixture of regret and remorse that was reflected in them.
They were so close... just an arm's length away...
But that distance felt like an unbridgeable gap.
Obito didn't have the strength to approach. Neither did Rin.
With her dying breath, Rin forced a slight smile for him.
The light in her eyes faded.
Her head fell to his chest.
The silent goodbye came to an end.
"Are you satisfied? Black Zetsu..." Kazuki asked softly. "Do you think I made a mistake? If I did, tell me as soon as possible."
"After all... this is all for the rebirth of mother Kaguya."
Black Zetsu clenched his fists tightly. With a leap, he emerged from the ground and glared at Kazuki.
The corners of Kazuki's mouth raised slightly, his eyes flashed, and he covered the Black Zetsu with Mirage Genjutsu, completely hiding his presence.
"If Uchiha Obito were to see you..." Kazuki whispered before Black Zetsu could speak. "Don't you think he would immediately come and kill you?"
"You can't even control your emotions for a moment. How can you take on the responsibility of resurrecting Kaguya?"
"Go aside and reflect on yourself. Look carefully at Uchiha Obito's reaction..."
"After the shock of awakening his Mangekyō Sharingan, his personality will undergo a transformation. If you plan to manipulate him with another identity, it won't be so simple. Don't overestimate your abilities, child."
Black Zetsu could see Kazuki's cold gaze. All his anger was extinguished in an instant under that icy gaze.
He was really impulsive.
He had left the ground impulsively using the Mayfly Technique, not considering that Uchiha Obito, who had just awakened his Mangekyō Sharingan and possessed Hashirama's cells, had extremely sharp senses.
If Kazuki hadn't taken action, there is a high probability that Uchiha Obito would have seen it.
But the problem is that Black Zetsu is not Uchiha Rin...
His body, resembling a carnivorous plant, was far from the image of a sweet kunoichi of the Uchiha clan, with shining eyes and a radiant smile.
Obito, who was still in pain over Rin's death, what would he do if he saw Black Zetsu with his terrifying appearance?
Kazuki said softly: "What a pity, Uchiha Obito's limit has come here."
"Otherwise, if I tell him now that everything he has experienced is false, maybe even his soul will collapse, right?"
"I can also draw more power."
Black Zetsu felt a chill run through his body.
If Obito knew the truth right now, his mind would completely collapse…
What was Kazuki trying to do?
Was it a warning or a threat?
Black Zetsu couldn't figure it out. All he knew for sure was that the man's mind was crueler and his emotional manipulation more terrifying than he could have ever imagined.
But he had to admit that Kazuki was right. His meticulous approach and extreme caution were worthy of admiration.
Despite having manipulated Uchiha Obito, Kazuki still warned Black Zetsu not to underestimate him, not to think that he could easily control him, and to observe him carefully.
Black Zetsu recognized this caution.
'This guy…' he thought silently. 'He still wants to revive the mother…' However, the uneasiness in his heart did not disappear. 'But he is too dangerous… I have a feeling he will do something even more outrageous than those bastards Hagoromo and Hamura…'
He hadn't lost yet.
If Uchiha Kazuki was allowing him to get close to Obito, then with the combination of Obito's Dojutsu and his cunning, there was still a chance to gather a group of followers to curb his actions and make him obediently follow the Eye of the Moon Plan.
Little by little, Black Zetsu's confidence was restored.
Black Zetsu was very pleased with Uchiha Obito's Mangekyo technique, an extremely rare spatial dojutsu...
With that power, his strength was terrifying. Even Uchiha Madara at his peak would have had a hard time facing him. That was the unmatched advantage of a spatial dojutsu.
Just as Black Zetsu's rebelliousness gradually grew, Kazuki turned his head to look at Black Zetsu, his Sharingan locked onto him.
"I told you…" his voice sounded calm. "I will show you a dojutsu that surpasses even the Infinite Tsukuyomi."
Instinctively, Black Zetsu met Kazuki's gaze.
In his right eye, the tomoe spun rapidly…
Taking the same shape of the complex and sharp figure as the Mangekyo in Uchiha Obito's eyes.
And at that very moment…
Kazuki's hair began to change from the roots, taking on a snow-white color…
The essence of his lineage was getting closer and closer to that of the Ōtsutsuki clan.
This is considered to have completely squeezed out the value of Black Zetsu, and the degree of fusion of Kazuki's bloodline has reached the limit of what the special ability given as a reward thanks to Black Zetsu has reached the limit.
Black Zetsu stared at him.
There was no doubt...
It was the same Mangekyō pattern as Obito's!
'This guy… this guy actually used a dojutsu to link himself to Obito and draw out his power…!'
He then turned his gaze to Kazuki's white hair and felt a chill in his heart.
'It can't be…' he thought uneasily. 'What if I'm his prey too? Could it be that this bastard used his dojutsu on even me...?'
'We are all children of Kaguya's mother!'
Black Zetsu was envious and frightened.
Kazuki's appearance at that moment was a reflection of what he had always dreamed for himself.
His body was no simple thing: in the original timeline he had survived combined Six Paths level attacks from Naruto and Sasuke, he could also control Obito even when he became the Ten-Tails' Jinchuriki… It contained within it the true essence of Kaguya's power.
However, its power was unbalanced.
Its survival and control were unsurpassed, but it lacked a real body and its development was limited.
Since leaving Uchiha Rin's shell, he had experienced for the first time what it meant to have a physical body… and he craved more.
He was Kaguya's son, he should be a noble and supreme being, not a specter who feared being discovered by Uchiha Obito so as not to be attacked by him.
This is unfair!
He didn't need to reach the level of Hagoromo or Hamura… A bloodline as powerful as Kazuki's would be enough.
"Your dojutsu…" Black Zetsu muttered. "It's real."
"I wouldn't lie to you, Black Zetsu." Kazuki replied calmly. "You're Kaguya's son, my brother. We're family."
Black Zetsu was silent for a moment before slowly nodding.
