Uzushiogakure ruins
Outside the secret room

Uchiha Itachi or Raven touched the gate of the room and muttered.
"It seems that only the member of the clan could enter there. Hokage-sama won't be pleased. Though, why did he reacted that way after finding out that Naruto-kun was here?... There is definitely something hidden behind that room that makes Hokage-sama so worried"
Itachi decided to explore the ruins to see if he could find out some clue.

Inside the secret room

Naruto looked at the spectral figure and asked again.
"You are the last leader of Uzumaki clan? What true abilities of mine are you talking about? Also what kind of the truth are you talking about? Didn't Uzu was destroyed by the combine force of three major villages?"
Jushiro looked at the young Uzumaki then decided to answer his questions.
"It's true that we were destroyed by the three major villages. But that's not the whole truth. We were attacked by the fourth village as well. No, to be more precise, we were betrayed"
Naruto after hearing that widen his eyes in disbelief and said shakingly.
"Y-you don't want to say that-..."
Jushiro nodded his head and gritted his teeth in anger.
"You guess right, Naruto. We were betrayed by Konoha. Right after the death of Second Hokage Senju Tobirama"
"B-but why? Didn't Konoha and Uzu were alliances with each other? Why did Konoha betray them?" asked Naruto not understood anything.
"The reason is simple Naruto. Konoha sold out Uzu to survive. Do you really think that Konoha stood a chance in that war, after the death of Senju Tobirama? Even with The Three Legendary Sannin and The White Fang, Konoha were outnumbered greatly. Just the Kin-Gin brothers of Kumo had managed to decrease the numbers greatly before that. That's why, when Sarutobi Hiruzen took the mantle of Hokage. He tried to negotiate with Kiri, Kumo and Iwa for Konoha's survival. After a while of negotiation, all four villages agreed that Uzu is the major threat, because of the unnatural abilities in fuuinjutsu of Uzumaki clan. Hiruzen together with his teammates and Danzo decided to use the seal of ally to enter Uzu. There the members of Uchiha clans used Sharingan to control some members of our clan to open the gate, so that the army of Kiri, Kumo and Iwa could invade. And just that the in invasion has started. Even though our clan was powerful we were greatly outnumbered and was wipe out in the end. But we still managed to kill off about 60% of the enemies" explained Jushiro with a solemn face.
Naruto gritted his teeth in anger and his widen in rage. Unconsciously his chakra began to leak out in waves and the wind blew around him.
Jushiro looked at the young Uzumaki and felt impressed at the amount of chakra he possessed at such a young age.
When the anger has subsided a little, Naruto took a deep breath and turned to Jushiro to said.
"Thank you, Jushiro-sama for telling me the truth. I never expected Konoha to be so rotten. And they even dare to wear the symbol of Uzumaki clan on their attires to mock us! Konoha and the other three villages will be crushed by my own hands. That, I promise you. Then I will revive Uzumaki clan once again and show this world that Uzumaki will never disappeared no matter what"
Jushiro shook his head and said.
"I didn't tell you the truth, so that you will take the path of revenge,young Uzumaki. I told you because you are not an ordinary Uzumaki. You are the only one that can awaken the Chōetsume, Uzureigan. It's a doujutsu that transcends time and could see the past, as well as the future when mastering the eye abilities. You true abilities lies within that eye, young Uzumaki. You are the one that will change the shinobi world with you action. I won't tell you what to do from now on, because that's your decision. I am already a dead man, I just want to tell descendants the truth about what happened 20 years ago. Whether you choose the path of revenge or forgiveness, I will still support you. Remember this young Uzumaki. The members of Uzumaki clan cherish the families above anything else. That's why in the history of Uzu, there were never a traitor in our rank. We cherish the bond we have with our clan and try our best to protect it. Now, I think it's time for me to awake your Uzureigan"
With that Jushiro approached Naruto and put his right palm on Naruto's right eye. He began to pushed his chakra to the eye. At first nothing happened, suddenly Naruto felt an intense pain on his right eye and cried out in pain. Slowly but the pain was subsided. Jushiro took his palm away from Naruto right eye and step back then said.
"Try to slowly open your right eye, Naruto"
Naruto slowly did as he was instructed. Jushiro looked at the eye silently. The eye itself is ice blue in colour. There was a ring around the pupil and out from it there were nine lines appeared. Three lines on top of the ring, three on far right and three on far left. Those nine lines when looking at the eye making the impression of the starting whirlpool.
Naruto panting heavily and looked around for the mirror. When he found it, he looked at his new eye and smirk satisfyingly.
"So this is my doujutsu, Uzureigan. It looked pretty cool. But I assumed like other doujutsus this is only the first stage of the eye, right Jushiro-sama?" asked Naruto still looking at his reflection.
"That's right, Naruto. Like the other doujutsus Uzureigan has three stage. Though, I don't know what its look like and is there anything else besides to look in the past and future. I only knew about the transcending time ability of the eye, because some millennia ago there were also one person that possessed the eye. He left some notes and they were in the library of our clan, though he only managed to find out only a slight power of Uzureigan and never developed further. That's why nobody knows what Uzureigan is true capable off" answered Jushiro.
Then Naruto decided to ask one question that he should ask from the start.
"Jushiro-sama, why I am the only one, that awaken this eye? I understand why nobody knows about it if the last wielder of the eye loved millennia ago. But why I suddenly awake the eye?"
"It's because you are the one that was given the title of 'Sadame no Uzumaki'. In our clan from long time ago, there was a prophecy that one day when the clan will no longer exist, one Uzumaki will appear and change the whole world, as well as bring Uzumaki back to full strength. I was not only a shinobi, but an onmyoji as well. That's why I could read the stars and knew that the future son of Kushina is the Sadame no Uzumaki" explained Jushiro crossing his hands.
Naruto widen his eyes hearing that. He never believed that his existence will be such important in the future. He always think of himself as far more advance then the others, because of the circumstances. But hearing that he will be the one, that will bring back his clan from his predecessor is a shocking surprise.
"I-I never knew that my existence is so important. I suspected that I belonged to a clan, because the unnatural ability in fuuinjutsu can't appear just like that, it's the trait of the clan. I am honored that the man of your status entrust the resurrection of our clan to me. I won't disappointed you and the rest of the clan... Though you mentioned that I am the son of Kushina? The only Kushina I knew is 'Akai Chishio no Habanero', that was so scary, that she beat up practically all boys in the academy. And that person is my mother?" wondered Naruto shivering when thought about that.
"Yeah, you are definitely her son. Though your personality is yourself. I only have a week before I will disappeared completely. Before that, I wanted to transfer and teach you all what I knew in my life" said Jushiro and looked at Naruto.
"But how? I can't be out of Konoha for too long, Sandaime will be suspicious" asked Naruto.
"No need to worry for that. There is a secret training room during the time of wars bellow us. It's a special training room called Time Chamber. In this room , the time flew much slower than in reality. 1 hour in reality equal a month in that room. You will be absence for a week. With that, I could transferred my most necessary knowledges to you. Also we will be training the Uzureigan and tried to develop it to the second stage" explained Jushiro to Naruto.
Naruto hearing about the special training room widen his eyes in surprise and exclaimed.
"Woah! The special training room that the time flew much slower than in reality? Never knew that such a room existed! Uzumaki clan is just full of surprise, eh?"
Jushiro just smirked at that then said.
"Well, if you don't mind then lets start our training"
Naruto just nodded at that. With that, Jushiro went to the wall where there is a kanji for ' Time Chamber' and pushed his chakra in to the Uzumaki symbol on the wall. The symbol glowed red and then stop. With that the wall split in half and an entrance appear.
Naruto just looked at the process silently, then when the wall was split in half, Jushiro called out to him.
"Let's go"
With that they both entered the entrance.

With Itachi

Itachi looked around the ruins for a while and still couldn't find anything useful only ruins. There were some Uzumaki symbols on some buildings, but its all useless to him, as all those were blood seal. Itachi sighed and said
"It seems I failed the mission. Hokage-sama will not be pleased, but I couldn't find other way to enter further in Uzumaki Castle. Naruto-kun must find something important to not come out till now. Guess I will return to Konoha and report the mission failed"
With that Itachi dissapeared in a swirl of leaves and appear at the symbol where he first arrived. He put the paper seal, that Sandaime gave him, and the symbol began to glow and teleport him away from Uzushiogakure ruins.
