"Danzo continued to target the Uchiha clan from then. But there were two Uchiha who could pose a serious threat to the higher-up's plan regarding the Uchihas, they were Shisui Uchiha and Itachi Uchiha." The atmosphere became tense just at the mention of the last name.
"Itachi!..." murmured Sasuke in a low voice.
"Well, they were the hope of Uchihas and they both awakened Mangekyo. So, they were corrupted by the Konoha higher-ups by the shit of fire. Shit of fire huh, I wonder what Yami might think about, anyways wrong world here"
Mentioning Mangekyo did surprise Sasuke, but the last part was incomprehensible.
"So long story short, Uchihas were unhappy with the blame game of Konoha about the Nine Tails incident and then they planned to rebel while Shisui proposed to use the ability of his Mangekyo to alter the will of his clan, and yes before you ask this, Shisui has this unique ability using which he can alter the will of a person, now this can help the village but Shisui was naive, I mean you cannot just change the will of one person and be done with this, right?, but before Shisui can do anything, Danzo ambushed him and killed him taking his one mangekyo Sharingan while the other was given to Itachi, well actually Shisui himself jumped off the cliff but you can say Danzo killed him. Then when the Uchihas were on the verge of rebellion, Danzo and the third Hokage wanted to retaliate and Itachi was chosen. He was given the order by Danzo to choose either his clan or village. Now, he chooses his village but he must understand you cannot clap with a single hand, if Uchihas are rebelling, there must be someone instigating it. It was Danzo of course. But your dear old brother took it upon himself to eradicate the Uchihas. I mean, in my personal opinion you could just be done with the rebels and Danzo and bam! you would be free, but no, our dude here decided that to save his little brother, he must kill every single person, children, infants, even those unborns, the civilians, hell even his parents, just for the sake of the peace he envisioned or the peace for which he was brainwashed. I mean who in their right mind would kill his parents just for some bullshit of fire, right?" Naruto just gave Sasuke a summary mixed with his thoughts.
"....." Sasuke remained silent throughout. He couldn't believe what he was listening to right now. Even he didn't know why he believed every single word spoken by the person sitting in front of him.
Suddenly chakra flared within Sasuke as his eyes started spinning and two tomoe suddenly appeared in his eyes. Yes, Sasuke managed to awaken or reawaken his Sharingan. Suddenly he got up and started running towards the door before a hand pressed him down to the ground again. He tried protesting and struggling against the grip but the hand like an unmovable mountain didn't bulge at all.
"Don't hold me back Naruto, I am going to murder Danzo or are you going to stand against me, I will kill you too."
"Easy there, a cheap copy of Garp, I am no Sengoku. If you want I will let you go but before going there, tell me, are you strong enough to infiltrate the root base? Believe me, even genins can kill you right now. And do you think I will stand against you for Danzo, who is indirectly responsible for killing my parents and also making my childhood miserable?"
This time Sasuke didn't reply and gave up his struggle. Naruto let him go this time.
"Listen I want to kill him as much as you, but first I have to clear some things." This time seriousness took over his face replacing his previous calm and easygoing demeanor.
"First, what will you do with Itachi, knowing he did massacre his clan killing hundreds of innocent people including children and even pregnant women, but all of this to save his kid brother. What is your judgement?"
Sasuke's face darkened. He believed in every word Naruto told him. There was a slight belongingness in his heart knowing that his brother still cared for him but then again it was replaced by disgust as he processed what kind of crime he committed.
"Itachi Uchiha, Danzo Shimura and his whole root along with Sarutobi Hiruzen need to die" Sasuke declared as if an emperor declaring his edict.
'Your Highness, it shall be done!' snickered Naruto as he questioned one important point.
"Where the hell did you get the idea to kill the third Hokage?"
"Isn't he in cahoots with him?"
"More like turning a blind eye but yes! Currently, you are in no place to say these words, so before taking any action better have at least Kage-level strength. Sarutobi Hiruzen will die a few months after our graduation, killed by his student so you don't need to worry about him. And even if I could kill them all, my peaceful life would be destroyed and I still want to peacefully cultivate strength.
Your training is lacking and you are simply wasting your potential. How about reaching Kage level before we start your crusade."
"Tell me, how to become strong!" Sasuke understood everything and this time he was not blinded by rage and revenge as this time he had a partner who was in the same situation as him. He knew the person in front of him had mysteriously become so strong that he was no match for him currently. He also has this queer ability to see into the future and Sasuke wants this power to accomplish his revenge for this he can only ask him.
"If you are thinking of gaining the same power as me then you would be disappointed as it was some sort of inheritance for the last Royal Uzumaki. All I can say is that Uzumaki clan has travelled beyond space-time and prepared this inheritance."
"Are you saying Uchiha is weaker than Uzumaki!" Sasuke shouted. He cannot believe that Uchihas would be behind anything. No matter how much calmly he might be currently compared to his cannon part the Uchiha pride won't go anywhere.
"Sigh!, listen, a great man once said, success is 98% perspiration, 1% inspiration and 2% attention to detail and you are lacking in all 3.
If you want strength, I can give you that, mind you, it will not be instant, you will have to grind for at least half a decade and you can have your sweet revenge and I will help you with that. The one who helped Itachi with Uchiha extermination was Obito/Tobi/Madara Uchiha as I have already told you and he was responsible for killing my parents.
As for giving you some reality checks, yes Itachi was strong because he awakened Mangekyou at 13 but again you should not think about it. Sure, at your age, he was a lot stronger, but his strength has stagnated. And you have at least six years before you reach Kage level strength, so patiently wait for it.
For the last part, I will train you and point you in the right direction, the rest is up to you to grind. I will also tell you many more secrets that I still haven't told you about. But before that comes an important question."
"What?" gruff Sasuke reflecting his Uchiha style.
"Will you join my crew? of course, I will be the Captain."
"If I get my revenge then sure."
'Seriously, the things I do to form my crew, manipulating 10-year-olds.'
"Well, this seals the Death of Konoha F4 and Itachi Uchiha then"
Sasuke didn't understand Konoha F4 but he sure understood Itachi and ignored the former.
.....
Meanwhile, Konoha F4 were having a secret meeting at the Hokage office when suddenly they heard some weird sound but it was quite melodious. The melody did give them a feeling of dread. For a moment they thought it was a sound-based genjutsu so all four of them tried to disrupt it.
"Kai!"
But it was not a genjutsu. When they looked towards the source of the sound, all four of them looked out of the Hokage office and they saw a weird scene.
Six people wearing strange clothes were performing a weird dance carrying an empty coffin. All six were wearing black suits, white shirts and brown shades with a black cap.
As much as surrounding people were enjoying the show, the Konoha F4 felt as if the coffin were their own.
