In a secluded corridor of the Root base stood two figures on top of a mud river; one of them had pierced a kunai straight through the other's heart.
These two person's were none other than Danzo Shimura and his now ex-subordinate, Sai Satou.
Danzo had a calm look on his face, he knew this was the end for the young boy; he was impressed with the way the boy had fought, but it still was not enough to take down a war veteran like him.
The only ones who even had a chance of killing him, were Hiruzen, the Sannin, Itachi, and Naruto Uchiha.
However Danzo was shell shocked when the Sai in front of him blasted, it was not a blast of blood but of Ink.
"A Sumi bunshin" thought Danzo in shock.
He quickly jumped away from the surface of the mud river; as the remains of the ink clone melted away in the mud.
Danzo's right arm was now open and not in his kimino, even the bandages on his right eye were removed; and the horrible truth was now in the open.
He looked around and saw Sai lying flat on the ground, he was panting quite harshly, and some blood was leaking from various parts of his body.
All in all, Sai looked like he had been through a meat grinder.
Sai was shell shocked, when he saw what was on danzo's right arm.
It had 11 sharingan on it, its skin was very pale, but its muscles looked far stronger than Danzo's left hand.
But more than that, Danzo had a sharingan in his right eye, and not any normal sharingan!
It was a Mangekyo Sharingan, it was spherical in shape, as the three tomoe had connected; and there was a cross right in the center.
"A mangekyo Sharingan...what the fuck!" thought Sai nervously.
Meanwhile Danzo was observing the boy more cautiously now, he had underestimated the young Anbu. Sai was far more stronger and smarter than he had imagined.
"If I had not used my genjutsu, he would have killed me. I just barely casted my illusion and escaped his attack; but he substituted himself with his ink clone in a flash, it seems luck was on his side," thought Danzo calmly.
"So you had these hidden in your hand, for all these years. You are a freak dickless!" said Sai in a disgusted voice.
"It doesn't matter what you think, I'll make you tell what made you betray me," said Danzo dangerously.
"You stole these sharingan from the corpses of the Uchiha, you really have no respect for the dead. But whose Mangekyo Sharingan is that?" asked Sai firmly.
"I don't have to answer that question, you are nothing but a nuisance now; you have lost," said Danzo seriously.
Sai used all the energy he had left, and got up from the ground. His muscles were in pain, he was feeling sleepy; but he had to go on, no matter what happened.
"Not yet, not yet!" thought Sai with determination,
Sai picked up his tanto with his remaining unbroken hand, he was finding it hard to breathe as Danzo's KI increased. It seemed the commander of Root was finally going to fight with full strength.
He then thought about the entire scene, he wanted to know how Danzo escaped from his lethal attack.
"I was so close to killing him, but it seems he casted a genjutsu on me with the help of his Mangekyo Sharingan...but Naruto's genjutsu prowess is strong...who in the hell has a sharingan that can cast genjutsu more powerful than Naruto's?" thought Sai frustratingly.
He then remembered all the deceased members of the Uchiha clan, they were strong; but their sharingan paled in comparison to Naruto's.
Only a few had more powerful eyes than Naruto...one was Madara Uchiha, but he was killed by the First Hokage, and Sai doubted Danzo could ever find Madara's body.
Next was Izuna Uchiha, who was Madara's brother; and Naruto's ancestor. Naruto had told him, that he had a Mangekyo Sharingan too...but he was killed even before Konoha was formed, so it couldn't be his eyes too.
Itachi Uchiha had a powerful sharingan, but he was still alive and was missing; Sai ruled it out.
"The who is it? Who was the most powerful genjutsu user of the Uchiha clan?" thought Sai with a frown,
His eyes widened in shock, when he realized whose eyes Danzo possessed.
"Shisui Uchiha, he had committed suicide but no one ever found his body. The most powerful genjutsu master of the Uchiha, his eyes created the most dangerous and strongest genjutsu, you took his eye, didn't you dickless?" asked Sai sharply.
Danzo was quite surprised and shocked as well, to think the boy could think and come out with the perfect answer; even when he was in such a difficult situation, was astonishing. Sai's level of intelligence, and his analytical abilities were of an Anbu captain.
There was no point in hiding it now, it was not going to change anything.
He was going to kill Sai anyway,
"Yes, it is his eye...however, your assumption about Shisui's sharingan powers is incomplete," said Danzo mysteriously.
"What do you mean?" asked Sai suspicously, he had a bad feeling about this.
"Shisui's Mangekyo is not only the strongest genjutsu casting sharingan...but it also has one more ability which made him feared in the entire world," explained Danzo briefly
Sai's eyes widened in fear as he realized the meaning behind Danzo's hint. His chances of survival were now very low,
"Naruto, I need your help," thought Sai worriedly
"Yes...it seems you understood. Shisui's Mangekyo not only allows me to cast the most powerful genjutsu of this world, but also gives me one more ability, that is..."
Danzo was interrupted from his speech when the entire base started shaking, and cracks started appearing in the wall.
"So it seems he is going to finish it," thought Sai in relief
He had done his job, he had stopped Danzo long enough to allow Naruto to finish Root; now he only had to survive until Naruto arrived.
And then, they would finish Danzo...
The Root Anbu shifted a few meters away from the barrier, their plan had failed as their secret weapon was defeated by Naruto.
Fu and Torune couldn't believe Rei, was taken out so easily by Naruto. Danzo, had told them she was powerful, but they had underestimated Naruto; and had solely relied on her Mokuton, which Naruto destroyed with his heavenly sword of Susanoo.
They saw Naruto pointing his ice sword towards Rei,
"Is he going to kill her?" thought Torune nervously
Not that he cared, but she was an asset of Danzo, and as such was valuable for their cause.
"Hyoro no Jutsu (Ice Dome)"
The Root Anbu watched in surprise, as a dome of Ice engulfed Rei's entire body in it.
Naruto stared at the remaining Root forces, he was feeling tired; he was quite shocked when he coughed up a lot of blood.
"Kurama, what is happening?" asked Naruto quickly.
Kurama gritted his teeth in anger, the boy's body was badly damaged due to the curse seal, and he didn't want to tell this to Naruto right now.
But it seemed the young blonde understood the biju's silence and the message behind it.
"How bad is it?" asked Naruto calmly.
He had felt that, when the curse seal had activated; he somehow knew, he had taken some serious damage. Sai had prevented Danzo from causing further harm, but it seemed the damage had already been done.
"The curse seal...released a corrupted chakra in your body which is destroying your body from the inside,'' said Kurama hesitantly.
"But if I stop using your chakra, it should have stopped this virus from spreading further," argued Naruto.
"My initial assumption was wrong, the curse seal took power from your mother's poisonous chakra; and when Danzo activated it, you were using my chakra. It not only stopped you from using my chakra, but also spread a poison across your entire body, the flow of chakra in your muscles was 4 times greater than any shinobi at that time, as a result it spread quickly. Even if your friend has stopped Danzo, the damage has already been done," explained Kurama sadly.
"What's the extent of the damage?" asked Naruto calmly.
"This virus or poison, whatever you call it, is destroying your body at cellular level, the more you use my chakra, the shorter your life will become. Even if you don't use my chakra, the poison will still kill you, if you don't find a very skilled doctor quickly," said Kurama worriedly.
"Can't you heal my body like always?" asked Naruto curiously.
"No, I can only heal minor injuries...this is far more complex, I'm sorry but it is out of my hands," said Kurama apologetically, he really was feeling helpless right now.
Naruto took in a deep breath, things were getting difficult for him; but right now he had to finish his mission.
"We'll talk about this later, don't worry I'm not gonna die, I have to look after Rei, you know!" said Naruto in a cheerful voice.
"Naruto...you don't have much time," said Kurama seriously.
"We'll get through this...and that's a promise!" said Naruto firmly.
Naruto then cut off the link, and prepared to fight his final battle with the remaining Root forces.
The Susanno's wings flapped wildly sending a strong gust of wind, which blew away some debris inside the barrier.
Naruto nodded to his 4 shadow clones, and they started releasing the barrier, as the purple wall was coming down, the Root Anbu shifted several meters away in order to gain distance and prepare for their attack.
"Hyoro no Jutsu (Ice Dome)"
Naruto pointed his heavnly sword to Rei's direction, and soon a very large dome of ice erupted from the ground and engulfed Rei's entire body in it; and formed a protective barrier in order to stop any attacks.
"I want all of you to get in Manji formation around this dome. Protect Rei at all costs," ordered Naruto sternly.
"Hai" said all the 4 shadow clones in unison.
The shadow clones quickly took out their swords and got into defensive formation around the ice dome.
Naruto knew his Ice dome was strong enough to withstand powerful ninjutsu attacks, but still he didn't want to take any risks. and as such had left his shadow clones as additional defense for his daughter, who was currently unconscious and defenseless.
The purple wall finally came down, and Naruto shot forward straight towards the Root Anbu's forces.
"Quickly, attack the wings and bring them down!" yelled Torune loudly.
"Shuriken Kage Bunshin no Jutsu(huriken Shadow Clone Technique)"
All the Anbu launched several shuriken towards Naruto, and performed the ninjutsu.
As a result the few shuriken, now multiplied into hundreds of shuriken that were like a wall and rushed straight towards Naruto's Susanno, some of them even had exploding tags on them.
In response Naruto swung his Hyorinamru in the air, and a powerful wave of ice was launched straight towards the wall of shuriken. The effect was instantaneous, and all the shuriken were frozend, and as they dropped on the ground they shattered to pieces as they were crystallized by the ice.
"Sensatsu Suisho (A Thousand Needles of Death)"
The Root Anbu watched in shock, as Naruto's Susanno released thousands of ice needles that flew in the air, and were now heading towards them quickly. Even the entire sky was covered by the attacks.
The speed of the attacks was incredible as the entire frontline comprising of half of the remaining Root Anbu forces got hit directly.
Fu and Torune watched in horror, as their men started dropping like flies as the ice needles impaled their bodies.
Some were hit in the neck, some straight in the heart, some in the head; the sheer magnitude of the attack was such that there were no survivors left.
"SHIT!SHIT!SHIT!"
"ATTACK!"
Fu and Torune heard some random Anbu yell, and many of their comrades made a banzai charge towards Naruto.
The few squads of Anbu jumped high in the air, and performed their attacks.
"Fuuton Daitoppa (Wind Release: Great Breakthrough Jutsu)"
"Fuuton Suidou no Tatsumaki (Wind Release: Tornado Tunnel Jutsu)"
"Fuuton Reppushou (Wind Release: Gale Wind Palm Jutsu)"
"Fuuton Kaze no Yaiba (Wind Release: Wind Sword Jutsu)"
"Fuuton Kazekiri (Wind Release: Wind Cutter Jutsu)"
"Fuuton Suraisu no Tatsumaki (Wind Release: Slicing Tornado Jutsu)"
"Fuuton Kaiten Shuriken (Wind Release: Rotating Shuriken Jutsu)"
"Fuuton Juuyouseigun (Wind Release: Gravity Force Jutsu)"
"Fuuton Atsugai (Wind Release: Pressure Damage Jutsu)"
All the Root squads launched their powerful wind attacks in a desperate attempt to cut Naruto's Susanno, but their eyes widened in shock as Naruto rushed straight towards them.
All the shuriken, wind blades, and various other attacks collided with the Susanno and caused a great explosion. The Root Anbu sighed in relief, thinking it was over now...
But Naruto quickly shot straight through and collided with the squads of Anbu who had led the banzai charge.
The Susanno cut through the bodies of Root Anbu like butter, their bodies were tore in half with blood spilling everywhere.
It was a terrifying scene, both Fu and Torune couldn't believe that not a single crack had occurred on the Susanno; it was as if it was made of steel.
"Let's finish this," said Naruto seriously
Fu and Torune saw a black energy gathering in Naruto's sword and immediately shouted, to the remaining 40 Root Anbu,
''Defensive walls now!"
"Doton Doryuuheki (Earth Release: Mud Wall Jutsu)"
The last of the Root forces, poured all the chakra they had left and formed a large mud wall; and soon they heard a loud roar in the base.
"Kokuryu Bofusetsu (Black Dragon Blizzard)"
The Root forces along with their two captains ran several meters away, and when they looked back their eyes widened in fear when a black dragon with dark red eyes, cut straight through their earth wall, and was now heading towards them.
Fu's eyes widened in shock, when Torune jumped straight towards the black dragon, and he had several explosive tags strapped on his chest.
"TORUNE!"
Fu's scream echoed in the entire corridor, as Torune was eaten up by the black dragon; but after a second the dragon was blown to pieces as the explosive tags that Torune had triggered off blasted him to pieces along with the dragon.
Fu and the remaining Anbu looked at each other, they knew what was coming. They were done for, their mission was a failure, their comrades were killed, their leader was nowhere to be seen.
They had no chakra left, and barely 40 of them were alive. The entire Root Anbu blackops were destroyed, the bodies of their now dead comrades was a proof of that.
"Forgive us, Danzo-sama. We have failed," thought Fu regretfully
Fu couldn't take this anymore, even though he was a Root captain, he had enough. His comrades were dead, his best friend was dead and Naruto was preparing his final attack.
"This is it," thought Fu tiredly
He gripped his sword tightly, he was a shinobi, if he was going to die; he would go down fighting. He wouldn't die in fear, and let Torune's desperate attempt to save them go to waste.
"Men, it has been an honor to fight beside you," said Fu proudly
The Root Anbu took a deep breath, they had been trained for such situations. They were proud shinobi, and warriors of Konoha.
All of them gripped their swords tightly and stood side by side with each other in a single line.
They took of their masks, and their eyes burned brightly with undying passion; even in the face of death, their beliefs never broke.
"The honor was our Captain Fu and Captain Torune," said all the 40 Root Anbu in unison.
A small smile came on Fu's face as his entire life flashed in his mind, it was time for him to lay down his life for Konoha.
"Are you with me?" asked Fu firmly.
"Till the end, Captain!" said all Root Anbu firmly.
Fu's charged straight towards Naruto, he could clearly see the black sphere that Naruto had launched at them,
"FOR KONOHA!"
The battle cry of the last Root forces rang one last time, as they marched proudly towards their death.
"Yasaka no Magatama"
There was big explosion that rocked the entire base, walls collapsed, debris flew everywhere, and loud screams could be heard in the base.
After a few moments, no voices could be heard; there was pin drop silecne in the entire corridor.
There was smoke in the entire corridor, and debris were scattered everywhere; and right in the center of the room was Naruto.
He was on his knees, blood was coming out of his mouth and both of his hands were trembling.
His Susanno had vanished, his vision was blurry and tears of blood ran down from his eyes.
Naruto looked at some of the remains of the Root Anbu, their blood, their screams, all of it would forever be wretched in his memory.
The sins he had committed could never be washed away, he felt miserable, horrible. He truly felt like a monster now.
This was hell, this was the true shinobi world.
Kurama didn't say anything, the mission was now almost over; but Naruto was already broken.
The light in his eyes was now replaced by a cold stoic look, his sharingan faded away. He looked at his hands that were soaked in blood of hundreds of people.
He had killed his friends, his superiors, his comrades, all of them were dead...
Only he was left...
"AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH HHHHHHHHHHHHHHHHHHHHHHHHHHHH"
His painful scream rang in the entire Root base, and his violent sorrowful sobs would forever be heard in the now destroyed Root base...
