When it came to extremes, no one was more extreme than Uzumaki Naruto.
He was the kind of person who could ruthlessly tear out someone's weakness, drench it in blood, and roast it over a fire. More importantly, most of the well-known villains in the Shinobi World had almost no secrets in front of him.
For example, Orochimaru, Kabuto, Nagato, Obito, and the Black Zetsu in front of him.
Silence. After Naruto's low growl, there was a full minute of silence. Black Zetsu was nearly in a state of shock, as if his system had crashed. He stood there, completely dumbfounded.
Naruto's threat to resurrect Kaguya and turn her into a*** left Black Zetsu's mind buzzing.
‘How could he know Mother? How could he know Uchiha Obito? Impossible! Absolutely impossible. He is just a Kyubi’s Jinchuriki.’
For the first time in a thousand years, Black Zetsu felt a chill run down his spine, though he didn't technically have a spine. A cold, creeping dread spread through him like a venomous snake, and his gaze toward Naruto changed.
"You know too much, and that's not a good thing. I've changed my mind. Either kill yourself now, or those two women will die."
Hearing this, Naruto didn't seem particularly nervous, and his eyes, which were fixed on Black Zetsu, relaxed. His entire demeanor suddenly became calm, a harmless smile appeared on his face, and he spoke calmly.
"Otsutsuki Kaguya should have a human form too, right? What do you think would happen if I mixed her with the bloodline of a sow? Hmm? What do you think, you leftover scrap of the Otsutsuki Clan?"
"Do you really not care about those two women's lives?" Black Zetsu glared at Naruto.
"Of course I care, and I also know you're just a clone." Naruto stood there, looking at Black Zetsu from a distance, "Uchiha Obito is just a pawn to you. You can discard him at any time."
"What are you trying to say?" There was an even stronger hint of fear in Black Zetsu's eyes.
"I just want to tell you that I know a lot more than you think, and it doesn't stop here." Having said this, Naruto paused, stared at Black Zetsu and spoke word by word.
"The Otsutsuki Clan is not immortal. All their information is stored in a container called 'Kama', which allows them to reincarnate and switch vessels endlessly."
"But this process isn't foolproof. Kama can be destroyed, and it can also be altered."
"...I don't understand what you're saying." Black Zetsu still had that poker face. He said he didn't understand, but the light in his eyes was enough to kill people.
"It's fine if you don't understand. Can you see this?" Naruto snapped his fingers, and with a ‘pop’, a coffin instantly materialized out of thin air.
Seeing this, Black Zetsu was stunned again, ‘Is that Impure World Reincarnation?’
He was very familiar with this move. Even though Impure World Reincarnation did not surprise him, Naruto didn't seem to need a sacrifice.
This was completely different from the original Impure World Reincarnation… it was on a whole other level.
"Do you see now? The Impure World Reincarnation is just child's play to me. As for the Rinnegan, there is no secret about it in my eyes." Naruto said.
"What are you trying to prove?" Black Zetsu glared at him.
"I just want to tell you that I not only know a lot, but I can do even more." Naruto spread his hands, stared at Black Zetsu and smiled, "Even that Kama can be broken and altered by me."
"And there's one more thing you might not know. I've already extracted the Kyubi from my body. Similarly, I can also safely extract the other Biju from their Jinchuriki."
"I'm stronger than all of you. I can gather all Nine Biju and the Rinnegan, and resurrecting Otsutsuki Kaguya wouldn't be too difficult for me."
"Just imagine, what would happen if I gathered all Nine Biju, resurrected Otsutsuki Kaguya, and integrated her Kama into the bloodline of a sow? Hmm? What if I added a bit of... gutter filth?"
The light in Black Zetsu's eyes flickered, and he looked at Naruto with a deeper fear. He wanted nothing more than to kill the man before him, but he knew he had to proceed with caution.
"So…" Naruto's face twisted into an extreme, cruel smile as he pointed at Black Zetsu, "I'm just warning you. If you don't want that bitch Otsutsuki Kaguya to turn into a lowly pig or dog, you'd better not mess with me."
"Otherwise, no matter where you hide, I'll find you and make you watch as Otsutsuki Kaguya is degraded step by step… first into the lowest form of human, then into a pig or dog, crawling on the ground."
Black Zetsu felt Naruto's cold words slithering through his mind like a venomous snake. The vivid image of that scenario played out before his eyes, fueled by Naruto's unyielding tone.
Shaking his head, Black Zetsu looked at Naruto, and Naruto looked back.
He didn't believe Naruto had the power to oppose his mother. Once his mother was resurrected, she would drain all the life energy from this planet, and that would be the end of it.
As for this lunatic in front of him, the more he ranted, the more it showed how much he cared about those two women. With this in mind, Black Zetsu felt a bit more confident.
The next second, he disappeared without another word.
Naruto stood there and watched the whole process, and did not step forward to stop a clone from disappearing. The sudden change made his heart even colder.
Before obtaining the Gate of the Underworld, Naruto had been wary of Obito's Kamui and Black Zetsu's pervasive surveillance abilities.
That's why he tried his best to avoid contact with Obito and Black Zetsu. After all, he knew he had weaknesses, and the later he entered Obito's radar, the better.
Naruto felt a sense of relief when he completed the Mission Line II and obtained Izanagi, as well as the Gate of the Underworld from the depths of the Land of Whirlpools.
This was his trump card. No one could touch his people under his watch, and he could hunt down Uchiha Obito and Black Zetsu without being led around by the nose.
The news about Hinata and Ino would spread soon. Naruto opened the Gate of the Underworld, stepped through, and disappeared without looking back.
…
Above the sky of Konoha Cemetery.
A dark golden gate materialized out of thin air. Naruto stepped out, gazing at the silent rows of tombstones under the night sky.
He murmured to himself, "You were the ones who stopped acting human first. Don't blame me. I really wanted to be a good person."
Two years ago, by chance, Naruto had accompanied Kakashi to this cemetery. At the time, the two had visited Rin’s grave together, so Naruto knew exactly where Rin's remains were buried.
He took a step forward with a familiar pace, but in the blink of an eye, he covered a great distance.
Finally, Naruto stopped in front of a weathered tombstone and took a look.
This tombstone had stood for over a decade, battered by wind and rain. Inside, there might be bones, or perhaps just a handful of ashes.
Whatever was inside, he could awaken something from it. This was the purpose of the Impure World Reincarnation, and also the reason it was created in the first place.
