3 Chapter 3: Yonko Red Haired Shanks

I will exchange with the Asura chakra of Naruto Uzumaki.

[calculating .... 114% value of the Shanks Template. Detected that the host has offered more than the required condition. Contemplating the outcome....

Congratulations host! the system can provide you with additional facilities for the template and you can advance yourself further than Shanks. Does the host want to continue with the exchange?]

Of course!

'I can get the Asura Chakra later and can also advance further than Shanks.' thought Naruto as he got excited to integrate Shanks's template.

So tell me system, how will I get these powers, will you give me the whole of it or do I have to get it slowly?

[The system has no such thing, the host will be taken to the system world for 30 years. The time is slowed, so only 3 seconds will pass here in the Shinobi world. The host will have his physique altered and Shanks's physique will be stacked on top of your Uzumaki physique. After that, you will be given Shanks experience and you will have to practice those techniques and Haki yourself in the system space. The system will provide you with all the nutrition and sparring partners including characters from One Piece world. You can set their level yourself.]

So I will get the sparring partners also, eh? Are they real people or just some system creation and who will I get?

[of course, they are system creations but their strength is equal to the real one, and their level can be set by you. The sparring partners include Edward Newgate, Gol D Roger, Warlord Mihawk, Marine Hero Garp and Rocks D Xebec.]

Holy Crap! Are you sending me to God's Valley?

I might just not survive in front of any of them. System, will I get injured?

[Host, but worry not, the system will heal any injury caused in the system space and you cannot die in the system space. These five are supposed to be at the top of the world and related to Shanks, one way or another, so they are chosen as your partners. Anything else?]

Just one question, I cannot fully integrate the Shanks template in 30 years.

[ Then the host is dumb, with Shanks physique and the best sparring partners and healing and nutrition provided by the system plus your own Uzumaki physique, even then you can't learn everything the host should simply sell his soul to the system]

why in Dumbledore's beard do you want my soul so much?

[ nothing, just employee shortage]

Okay, but what about psychological well-being? spending 30 years in the system space along with you is definitely not good for my brain.

[ Worry not host, you can also interact with your sparring partners, even if they are not real people. Apart from that, the system will take care of any psychological strain caused in your brain, so everything will feel fresh and new.]

One more thing, system, what about the gift, how am I getting more powerful than shanks?

[That will only be unlocked after you defeat and achieve 100% Shanks template which includes his battle experience.]

Fine, don't tell me. Humph!

Let's begin then.

[ Starting Exchange......exchange successful. The Asura chakra is absorbed by the system.]

[ Transfering host to the system space....]

A bright light enveloped Naruto and the next second he vanished from the spot. The sensor Anbu outside detected the anomaly and immediately took action, but as soon as he reached the window and found nothing there, he proceeded to enter the house but the next second he found Naruto there on his bed.

The anbu becomes confused for a second. Wasn't there no one there, was he hallucinating, then he tried sensing Naruto's chakra and found nothing strange, but looking at Naruto he became more confused because Naruto's body looked quite buffed up. And Naruto was also looking towards him.

Did he get detected and what is this extreme sense of fear he feels, as if he standing in front of a conqueror and he is just an ant he can step on any time?

'No, this must be my mistake, maybe I am thinking too much, it might be due to the nine tails inside that boy.'

With these thoughts, the anbu retreated immediately. 

3 seconds earlier:

"Woah! What is this place" exclaimed Naruto as he arrived at the system space.

It was a lush green field with mountains in the background and he could also smell the sea at little distance from him.

[ Integrating Shanks physique now. You might want to get ready host, as it can be a little painful.]

I am ready.

'holy shit what the hell is this pain' A sharp feeling of pain ran through Naruto's body as the system began the integration of Shanks's physique into Naruto's body.

After a few minutes, the pain subsided as Naruto felt a little relieved and also a little more powerful and perceptive.

Meanwhile inside Naruto's mind space:

"What the hell is happening outside, how come I am blocked and what is this new feeling I am getting from the brat" The nine tailes roared after getting this uncomfortable sensation from being blocked.

Back to Outside:

Just as Naruto was finished with the physique another system notification ran:

[ Physique Integration complete! Now commencing with experience integration. Get ready host as the system will integrate the experience of Shanks in your memory, to you it will be from a third-person point of view. Recommending host assimilate the experience for a week before starting with the training. All the required food is available in a pantry 15 kilometres south and also weapons and training equipment are available in the armoury next to the pantry. The sparring option will be available from the next month. Good Luck host!]

I will definitely finish the assimilation and 100% of the template in 10 years, dattebayo!

The next moment Naruto fell dizzy and started losing consciousness but with sheer willpower held on. The next moment he sat in a meditative posture and started assimilating the whole experience of Shanks, all his battles and his whole life.

1 week later....

'Finally, I am done with this experience of assimilation. Now let's begin the training part.

Now for Shanks, I need training in two things, Swordsmanship, and Haki. As of now, I can only train for physical strength and Observation Haki, and based on the nutritional supplements and the equipment for training which somehow include an automated Observation Haki trainer for till advanced level where I can use future sight and also some of the hardest metals for Armament. Damn, this system is hardcore.'

With that Naruto's eat sleep train repeat routine began.

Six months later...

'This Uzumaki physique is perverted, no matter how much I train, the stamina is almost endless, plus with shanks physique, which belongs to the pirate world, where battle lasts almost for days on average, like those between admirals. My physical strength is already close to Rob Lucci and I have already learned one of the six marine styles- shave.

My Observation Haki though is still a little behind, I have started sensing but this Uzumaki physique is interfering too much. I can't shut the shinobi sensing, as the observation haki is a little different than them so it isn't helping either.

Gotta increase my time for this.'
