Fuinjutsu and Labratory

It was just one week later when Mito called me.

When I visited, I could see Kushina with red eyes and a smiling Mito that sat there.

"So you are here? Then we can begin, Kushina."

Kushina only weakly nodded, knowing that Mito will die afterward.

The transfer of the Kyuubi went without any struggle. The only thing indicating that the Kyuubi was now in Kushina was the seal on her stomach.

Mito was slowly getting older and after some minutes, there was only aged woman that showed some signs of being a beauty when she was younger. She smiled deeply at Kushina and looked really happy.

Then suddenly the door was pushed open

"Grandmother!"

Tsunade entered the room and could only see the aged beauty, tears slowly dropped down from her eyes.

"My child. This looks like a nice death."

After some minutes of silence and tears...

"Don't worry, my children. Death comes to all of us, it is natural. I can see Hashirama now, I will watch over you, so don't worry. I want you to give Izumi and me some time to talk."

Reluctantly both Kushina and Tsunade left after some convincing from her.

"So, Izumi-chan, what mysteries do you hold?"

"I apologize, Mito-sama. It could be a bit uncomfortable."

My Ryajigan activated and my eyes went green. Mito looked a bit surprised but still didn't interfere.

I looked at Mito and activated my ability, slowly gaining control over her body.

On Mito, my power would only work for 6 seconds. I have to be fast.

Searching for all of her Fuinjutsu knowledge without any filtering, I absorbed all of them.

Like this, the 6 seconds were over and I managed to get all her knowledge. After I was back in my body, unimaginable pain overcame me...

"AHHHHHHHH,*grunt*"

I fell to the ground and wriggled like a caterpillar. I could feel my consciousness going black.

'I cant blackout, I have to hold on!'

I gritted my teeth so hard that blood was coming out of my mouth because I bit my tongue.

The pain continued on for two hours until I could barely feel it. I slowly stood up and tried to not fall down again.

Mito looked at me surprised and relieved, she noticed that she lost something and that it was her complete Fuin-Jutsu knowledge which she cherished a lot.

"That is really an evil ability you have there, little child. Don't ever let anyone know of it!"

"Thank you, Mito-sama." I bowed towards her in gratitude. I could feel all of the knowledge slowly taking shape and clarity began to come to my mind.

"Sent Kushina and Tsunade back in!"

They both came back a few minutes later and I excused myself, wanting to learn of my new enhancement.

After going back home and greeting my parents, I went to my room and closed the door.

I meditated for hours to slowly watch all of the memories I gained.

'So this is Fuin-Jutsu. It is like programming from my past life, but it is with a completely different language and other rules.'

'I can now do seals just with my chakra and I learned so many seals, even ones that Mito already forgot seemingly, are ingrained into my brain.'

I found a good seal, which would aid my training and my now underdeveloped body in comparison to my mind.

It is the gravity seal, which can increase the gravity my body carries. The seal is a complex one that only some people could do, cause it bends space to fit the requirements of the wielder. Most Fuin-Jutsu grandmasters used this in battle which was very helpful, but the real usage would be to train your body which Mito did. This should be the reason why Tsunade was that powerful, probably Mito used her seal on her.

After printing the seal on my body with my chakra, I activated it to Level 2, it doubles the gravity.

'Hmm... I can still go one up. My body is already strong enough to handle two-times gravity.'

Pushing the seal to the next level, I could feel the strain on my body. It was like you were running without stopping.

'This should do for now'

I could feel my Zanpakuto vibrate and directly entered my mindscape as I already had an inkling of what happened.

In my mindscape, I saw my katana vibrating like it is telling me to touch it. And that's what I did.

After holding it in my hand I could feel the power that was emanating from it.

"Ban-Kai!" My whole mindscape began to shake and rattle, everything in a radius of 5 meters caved into the ground. Slowly Onmyo took shape in front of me in his full glory. He looked a bit different than before, he was shining and had much more refined scales than before. His red eyes deepened and his black was like it would suck everything in it, while the white side was shining so much it blinded my eyes a bit.

I instinctively knew what my Bankai power-up was and I knew that I was officially considered Overpowered.

It was a domain that was around 5 meters from me, where I could control Yin-Yang, negative and positive, death and creation, basically everything. In my mindscape, I couldn't use it to its full potential but nothing can surely escape after they enter my domain.

Trying my new ability a bit out in my mindscape and fighting with Onmyo.

He told me that I cant summon him to the real world yet as I can't take the burden of part of my soul leaving. In Bleach, they try to summon the spirit of the Zanpakuto for 10 years. It is not because the spirit doesn't want to come out, it is to train their wielder and protect him from damage if they were just summoned like so.

After this part was over, I wanted to get started with my plan. It was to create a laboratory in my mindscape after I have enough Yin for this endeavor.

Soon, I will be able to analyze all the blood samples and finally create the A.I. Chip with Fuinjutsu. But for that, I would need the Hardware and I am not sure if I can buy everything.

Money also isn't a problem anymore as I can just create it and transform it to reality with my Zanpakuto.

I am pretty sure, I would need to go on travels myself and see if I can find any alternatives for some things. I will try to do this while I am on ANBU travels.

For now, I should try to see if there is anything interesting in the blood of the different clans. I was very excited, having already waited a long time now.

Let's see, I took the blood first under the microscope and put two different blood types under there to see if there is any difference. First was the blood of a ninja and one of a civilian.

I already expected something like this, the Shinobi-Blood has a higher rate of activity. The blood that is in my mindscape was something like stopped in time, but now I just resumed the blood's time and saw that the activity was getting slower and slower.

My microscope was one that wasn't existing in the World of Naruto, it was one of the most high-tech machines even in my past life, where not everyone could get one of this caliber. I could see any minimal changes that happen to the blood.

After going through every blood sample, I had, which was a lot. I noticed subtle differences in the blood of the Uchiha, Hyuga, Uzumaki, and Senju ones with the others. I assume that it has something to do with Otsutsuki. I think I will need to get some blood of the Kaguya-Clan too, to be completely sure.

If I had some living subjects, my work would be much easier. I have to wait for about two years until the war. That is when my research will probably skyrocket.

Their DNA was inherently different than normal humans. The nucleotides in their DNA-String were as much as 5 and every clan had a different one in their DNA.

I think the Kaguya-Clan also has one. What would happen if all the nucleotides were combined?

High-precision machines would be needed but I will be able to create them.

Wait for a second..., cant I just create the components for my A.I. Chip? Let's try it out.
