Knowledge 

Naruto Turned towards Kurama and spoke can you Understand me?

Kurama raised his eyebrows and spoke in an angry voice Yes. You little brat. Naruto thought for a few seconds and said Kurama is your name, am I right?

Kurama stood up and asked in an angry voice. How do you know that name? Well, you can say I remember everything from my past life. Kurama was now interested.

Naruto started telling him about the world and how he died. Kurama laughed about he died. They hit off from then onwards, Naruto said to Kurama. How he doesn't know about the things work.

Kurama said to Naruto enter said cage. Naruto entered and Kurama raised his finger and brought it near his forehead. A lot of knowledge started to enter his brain.

It has been a few hours since his brain started absorbing knowledge that Kurama has had for thousands of years. Naruto turned to Kurama and said; Well, the Fuinjutsu looks like programming from his past life. He was studying computer science before he came into this world.

He was thinking about; How to use Fuinjutsu on a whole new different level than his father. Kurama said you can not move for the next four years without raising the eyes of the other party.

Naruto started to tell him about what he wanted to do. At first, even Kurama was raising his eyes. Is this even possible?

He told Kurama how he can use Fuinjutsu if this worked, even Madara will have a hard to fight him even at his full strength. Kurama, are you sure it will work?

Naruto turned towards him. If you have given me the right; knowledge about Fuinjutsu' it will work. I have to create a correct algorithm that triggers the function at a certain operation.

Kurama, well you have four years to test inside your mindscape. So how do I change this mindscape? It's your mind to change it how you desire.

Naruto sat down and started thinking about what he wanted.

Then everything started to change into binary. Even the seal started to change, everything changed trees, mountains, lakes, and the whole biosphere started to come into sight.

When he touched a nearby tree his hand passed through the tree. So it's like virtual reality, you can see but can't touch.

From there on Naruto, started to test Fuinjutsu to create an algorithm; that will work perfectly as possible.

His physical body was growing by drinking milk and sleeping. His mind was working to create a system that will put every Fuinjustu master to shame.

Naruto turned to Kurama and asked what do you think is the last date I can put this on my body. Kurama thought and said when you are six. After that, it will not work or will be very painful to put it in place.

So by the time, I am four, I have to have a working Prototype. Kurama can make sure my development is slowed down by fifty percent. Come near me kid put your hand out against mine.

I am going to sync our chakra together it's gonna expand your chakra coils and capacity first and then become stable.

Naruto put his hand against Kurama's and felt something start flowing inside his body until it felt full. Naruto asked is that chakra? Kurama nodded and told him about his new ability to sense emotions.

Naruto wanted to check his ability as he has seen in anime. He opened his eyes around him and sensed people with different emotions some were like anger, curiosity suddenly sensed a few people without emotions, and he guessed they are root Anbu.

He started feeling drowsing fall asleep as this has taken a toll on his body.

{ Time skip no jutsu }

It has been three since Naruto started to work on his project. He has created multiple algorithms only thing that was stopping was his body and the algorithm that will join them together.

As he woke up orphanage mother called everyone to eat breakfast. she was frowning seeing Naruto but still put breakfast in front of him as Anbu was watching her.

Naruto ate and went to practice his handwriting for Fuinjustu as he needed it for creating the seal.
