Jon leave with the revolutionaries and they put him in bed immediately. The journey will take about 10 days because it's a normal ship, unlike the ship Jon used to go to Impel Down. Jon decide to check the gene modification procedure and timing.
'System, how long will gene modification and body rebuild operation going for?'-Jon
[Gene modification take 3 days, but with body rebuild it will take 7 days.]
'A week huh? I can do it on the ship and finish it before we reach RA's base. I think i will take body rebuild, i have the necessary SP and it will make my progress faster. Money is exist to be spent right?'-Jon
Jon call the guard and ask the crew to not disturb him for 7 days. He said that he will do a secret technique that will help him cure himself and it take 7 days. The guard is confused, but he agree nonetheless. There are many misterious power in this world, so it's not strange that someone can get better from grave injury in a short time.
After the guard left, Jon immediately ask the system to start the procedure. Suddenly white threads appear around his body and wrap him from head to toe. He can't move his body, and when the threads cover his eyes, he lost consciousness. Now Jon looks like being inside a very big white cocoon.
When he lost consciousness, Jon feel like he is drowned in the water. But he's not suffocated at all, he feel comfortable instead. He look around and see nothing but darkness.
"Where is this?"-Jon
[This is Host's mindscape]
Suddenly a blue cat with white wings appear in front of him. Jon know that it's the system that use Happy's appearance.
"Why are you appear like this?"-Jon
[Because system is integrated with host mind, so i can appear as my AI.]
"Ooh, that's good. By the way, what do you mean by mindscape?"-Jon
[It's like the place where Naruto meet and communicate with Kurama.]
"Oh, then why am i here?"-Jon
[When the operation started, host mind is pulled inside to make you not feel the operation.]
"Then why it didn't happen before when i'm unconscious for 3 days after fighting Aokiji?"-Jon
[Because it was a mind operation, so the mindscape is being rebuild, and host can't enter it. Host was put in a sleep state at that time. Now host is put in a conscious state, but can't move your body at all.]
"Huh? So what am i supposed to do in this state? I can't even train in here right?"-Jon
[You can]
"Eh? I can?"-Jon
[Yes, but it is only an imagination, you can train your moves in here, but it will not make your body or attack stronger. It will help you refine and revising your techniques to make you execute it better. But ninjutsu training is prohibited because it use chakra.]
"So it's like polishing my blade to make it sharper, but not tempering it to make it stronger. Well, it's better than doing nothing."-Jon
Jon then train his sword art, because he know his Susanoo will use 2 swords. He also feel that they are ninjato swords, so his Kusanagi is not suitable. He buy 2 wooden ninjatos and train with it. He also buy a manual for 2 swords style and then train by sparring with a clone.
"Ugh, using 2 swords is harder than using 1. I never really use two sword style and only use my left sword as support. I need to train my left hand so it will have power like my right hand. 2 swords style need 2 hands in perfect coordination."-Jon
Jon just keep training like that for days, and then in 5th days, he get a surprise.
[Ding!
The Goddess have sent you a gift.
Uzumaki's Adamantine Chain Seal]
"What? Adamantine Chain is the one that Kushina use to seal Kurama right?"-Jon
[Yes, with Adamantine Chain, the Nine Tails was never lose control when Uzumaki Mito & Kushina become the jinchuriki. But they have mastered her chains, so it can hold an entity like Nine Tails. Uzumaki Karin's chains at the fourth shinobi war won't be able to hold even the One Tail.]
"So i need to master it first before using it to seal Kurama?"-Jon
[No, the goddess send this with enough power to hold the Nine Tails until you can befriend him. But if you want to use it for another purpose, you need to master it yourself.]
"So i can seal Kurama's chakra right now?"-Jon
[Yes, proceed?]
"Of course, proceed. I want to meet that man hater fox right now."-Jon
[Sealing Nine Tails inside host body with Adamantine Chains Seal, start! Infusing Nine Tails chakra, activating Adamantine Chains Seal.]
Suddenly a red chakra enter Jon's dark mindscape and then 6 bright yellow chains with spikes come out from his back. Jon feel like being Kaneki with his Kagune right now.
"Oshiete yo, oshiete yo, sono shikumi wo..."-Jon
[Host, please focus!]
"A-alright, sorry, i like that song"-Jon
"RAAAWWWRRR"-Kurama
Suddenly Jon hear a roar from the orange fox that start to manifest in front of him. The seal looks excactly like Kushina's seal, but then Jon decide to take off the spikes that pierce Kurama's body. He change it into red tori gates like what Naruto use to hold Kurama after he take it's chakra.
"So this is the Nine Tails Fox, Kurama."-Jon
Jon's eyes glittered and he approach the orange giant fox. He touch the fur and run around to see Kurama at all angle.
"RAWR, DAMN YOU HUMAN!"-Kurama
"Ah, hello there Mr. Fox, i am Jon, nice to meet you."-Jon
"It's not nice to meet you for me. So you're the next human that is used to seal me huh?"-Kurama
"Uh, it's a little complicated to explain it to you."-Jon
"Hmph, it's all the same, you humans want to use my power. These chains, another Uzumaki huh? Just when i can get away from that woman's chain, now i'm chained with the same chains again."-Kurama
"Eh? That woman? Do you mean Kushina?"-Jon
"Yeah, that red hair bitch... Hmm? Now that i take a look at you, you don't have a red hair, are you really an Uzumaki?"-Kurama
"As i say, it's a little complicated. Uh, are your previous jinchuriki really Kushina? Is it not Uzumaki Naruto?"-Jon
"The last thing i remember is that damn Minato pull me with Shiki Fujin and divide me from my real body. Wait, DAMN YOU HUMAN, HOW DARE YOU MAKE ME ANSWER ALL YOUR DAMN QUESTION. COME HERE SO I CAN EAT YOU!"-Kurama
"I'm sorry, but i don't have a hobby to be a meal."-Jon
Kurama keep cursing at Jon so Jon just use the chains to close his mouth.
'So this Kurama is from before Naruto become a jinchuriki?'-Jon
[Yes host, the Goddess take some of his chakra when it was sealed by Shiki Fujin. Then she raise the chakra and try to erase the soul, but she didn't succeed. That's why she need devil fruit that is soul less.]
'Why did she need Nine Tails Fox?'-Jon
[Because she is a Fox Goddess, and want to have nine tails, it's the pinnacle of power for Fox Gods. But there will only be 1 nine tailed God, and her brother has become that God. To get the nine tails, she will need to kill her brother, but she won't do it as she loves her brother. So she try to use Kurama's chakra but she can't remove the soul from it. Then the God of Reincarnation, her husband, found out about devil fruit, but Gods can't go to mortals world]
'So he found his chance when i come. They also can only get Kurama's chakra from Shiki Fujin because it's not in mortals realm. That's explain everything to me now, so we're business partner.'-Jon
Jon want to train again, but Kurama still try to disturb him with chakra wave. Jon got a headache, and think of solution. He can't leave the mindscape for 2 more days, so he will become crazy if this Fox keep doing this.
"System, can you show him my memories?"-Jon
[Yes, but are you sure host?]
"I don't care, we will always live together from now on, so it's better if he know the situation. He need to know a lot, especially my reincarnation, Naruto's story, and this world. My memories will help him understand the situation. I haven't show him my sharingan, because i know he hate it, so it will be faster if he see my memories."-Jon
[Understood host, proceeding memory projection.]
"It will looks like a brainwash, but it's needed to calm that man hater fox."-Jon
Suddenly a thick fog surrounded Kurama and the mind scape become quiet again. Jon then continue his swords training and the system tell him that it will take a week to show his memories to Kurama. Jon also train his taijutsu, but then he feel that the mind scape is so plain.
"System, can i decorate this place?"-Jon
[Yes, it cost 500 SP, and you can always change it.]
"You really put a price on anything huh? Your price also keep going up. Well it's okay, it will make this place look prettier. It will be better for that Fox too if he didn't see a dark empty place all the time."-Jon
Jon then decorate the place to be a grass land with many flower bed and it's surrounded by forest. He also make a lake and filled the mind scape with many animals and fishes. They're not real animals but it looks better now. He also make a big house and decorate it with pictures.
"It looks more like a paradise now, why didn't i think of this since the first day?"-Jon slap his forehead
Jon then train again and his sword art has become more refined. At the last day, Jon decide to train other weapons. He train the Gunbai, because if he can use the Gunbai at the previous war, it can change a lot of things.
"It's not as easy as i thought it would be. It's easier to use sword even when i just started using it. The air resistance when i swing the fan is big, and it's hard to use the Kama and chain."-Jon
It's hard, but Jon like challenge, so he will not give up that easily. He train the weapon for many hours until it's time for him to wake up. The system's notification has appear and Jon get ready.
In Jon's room, the big white cocoon has turn into big black cocoon. It keeps beating like a heart, and then a crack appear in the middle. The crack keep getting bigger and bigger until it become a big line from head to feet. Then the cocoon explode and the threads flung everywhere. The explosion alert the crew.
"WHAT IS THAT?"-Captain
"It's from the guest room, the other crew members have gone to check it."-Crew A
"I hope he's fine, Dragon-san has ask us to take care of him."-Crew B
The members that go to Jon's room are surprised seeing the condition inside. Black threads are sticking everywhere in there. The walls, and furnitures are covered completely by black threads. The only one that isn't covered is Jon that still laying on the bed, but his bandages, and even clothes has gone too, so the mens blocked the womens from entering the room.
Jon's body looks fine without any injury or scar that he got from his fights and surgery. They all gone and he looks like being born again. He also grow taller and now his height is about 2 meters. His body looks more muscular but not big, and only proportional, even his little man has become a bit bigger. Suddenly Jon open his eyes and look around the room, then he sit and ask,
"Do you have food?"-Jon
