In Naruto as Ten Tail

'It's tough to advance as I level up,' I mused, observing the figures gathered around me. "Have you all decided that this is what you want?" I asked, addressing them.

This morning, they had come to me with a request about traveling the world separately. 

They nodded, awaiting my answer. "Come back in 20 years, or when you get bored. I won't go with you. You can do whatever you want, but don't go running around wildly, especially you four," I said, looking at the troublemakers - Kurama, Son Goku, Shukaku, and Gyuki. 

They nodded, though I knew it was useless to tell them.

With their agreement in mind, I continued refining my chakra and strengthening my powers. As time passed, my first tail was nearing completion, a symbol of my growing strength.

Once I gain all my tails, you will be the first to be the victims of my training results. Nothing much, just a little bit of sparring. You are in for a surprise once you come back, hehehe.

The mentioned four suddenly shivered and looked around hastily. Ignoring them, I turned to rest. "Take care, all of you. Once you get tired or are in any harm, come back or call others. I have already told you about the telepathy, so you can talk to each other while still far away."

Matatabi came jumping at me, "Big brother, I will come back fast. I just want to see what changes were made in recent years. Kokuo will go with me as well." The silent girl also spoke, "Brother, I will be back soon."

I smiled at Matatabi and Kokuo, knowing that they were eager to explore the world beyond our sanctuary. "Enjoy your journey, but remember to stay safe and use your telepathy to stay in touch. I'll be here waiting for your return."

With that, they nodded and turned to leave, their tails swaying with excitement. The other tailed beasts also expressed their farewells and well-wishes as Matatabi and Kokuo ventured into the unknown.

As I watched them depart, I couldn't help but feel a sense of pride in how far they had come. They were no longer the wild and uncontrollable beings they once were, but rather individuals with their own goals and aspirations.

As I entered my dimension, I prepared for my intense 20-year training regimen. Learning advanced seals would be crucial; with them, I could manipulate the time in my dimension as well.

  It was always my go-to training ground, hidden from the watchful eyes of that senrigan girl and others. By the time she came looking for me, I would be the strongest being on this planet, at least according to my calculations. 

That guy needs 1000 years to recover, he might eventually discover my existence. There is Momoshiki too, he will pose a significant threat. But I would be ready for them.

A pitch-black portal appeared before me, and my third eye opened. It revealed a blood-red eye with three concentric rings and three tomoe on two of the rings, while the third one remained empty. 

The eye gleamed with a faint, eerie light, and its intense red hue resembled fresh blood, exuding a sense of power and dread.

While on the outside it's like the eye never opened. I entered the portal and it closed behind me.

Stepping through the pitch-black portal, I found myself in a vast grassland. 

I surveyed the area and, with a simple gesture, raised a wooden platform from the ground. 

Numerous chakra-infused wooden pillars emerged, their bases made of metal, and a massive, thick pillar rose at the center.

Creating clones of myself, I assigned each one to a different pillar. 

These pillars served as the foundation for various seals aimed at enhancing concentration, stabilizing the mind, and promoting healing and recovery. My intense 20-year training had begun.

As my clones diligently worked on their respective seals, I observed their progress. When the seals were completed, I initiated a final seal, known as the "chakra convergence seal," with myself at the center. This seal allowed my chakra to accumulate and increase in quantity.

As the clones dissipated, my chakra reserves expanded while the amount of chakra I had started decreasing at an astonishing speed, but at the same time, the concentration of my chakra increased. This delicate balance allowed me to push my chakra control to its limits.

Not many were aware that when Kaguya and I were one entity, we shared a unique connection. 

Even though we existed separately, she had the ability to tap into my power as if it were her own. However, after our separation and the distribution of my chakra, my strength had significantly diminished.

My current training aimed to regain that lost power and reach new heights of strength and control.

Now that I've gained consciousness, I can't be merged with her again unless it's through a soul bond, but those are only for my wife or wives. 

We are separate beings now, without any connection.

So, for her to be unsealed, she needs the tailed beasts combined with my chakra in the Gedo statue, which was my old husk. 

It's now useless, by the way, and can only be used as a carrier. 

I do have another way to rescue her, but that's for later. Now, let's continue. Separation and convergence, with each repetition, the density of chakra increases.

After a year of relentless training and refining my chakra control, I had made significant progress. The separation and convergence technique I had been using had allowed me to steadily increase the density of my chakra.

Opening my eyes I looked at myself through the screen. I had a whole new tail. And my chakra density reached its limit. It is as large as 1 tails chakra while the density is triple the previous density.

UPDATE

COMBAT POWER : 3 TAILS

(WITHOUT OCULAR POWERS)

9 (TAILS WITH OCULAR POWER)

]

I was more than satisfied with the results. Now that this is done, let's max out the shadow clones with the Flying Thunder God technique. 

They will help me move around when I don't feel like moving on my own.

Another year went by, during which I first maxed out the shadow clone technique, which gave me a good skill. 

Then, by spamming shadow clones, I used them to max out the Flying Thunder God technique. The results were astonishing. 

The Flying Thunder God is more than it seems, and even Tobirama couldn't discover its full potential after creating such a thing.

Even my chakra control increased incredibly within this year. Now it's just one step away from perfection, and I'll get there in these 20 years of my training.

In the third year, I focused on increasing my chakra to the level of 2 tails. 

I used a gravitational seal and performed several sets of techniques only used by fox yokai, which I obtained from the system. They were of the highest quality out there. 

With a bit of improvement from the system to suit my needs, I had a perfect technique to increase the results of my training by five times.

I have a new half fully grown tail as I reached a new level of strength. I will continue this for 2 more years.

Within the first year my strength reached 3 tails and I have increased a great deal of my chakra. While my 2nd tail is now fully formed.

Since due to  compression of my chakra the amount needed to form a tail fully keeps on increasing while my body is now more than 100 meters in size.

I will need more and more chakra as the number of tails increases but once I become a ten tailed fox I will rival Hagoromo with chakra alone. But once I make myself a body and add natural energy I will surpass him.

Now five years have passed since my training started. I am now officially a three tailed beast and my chakra quantity reached 5 tails.

But I also came to know that once I reach 10 tails my chakra will also compress once more and I will be left with 10 tails amount of chakra but the quality of that chakra will be 10 times more.

Which doesn't mean that I'll be 10 times stronger than Hagoromo but I will have more attack power. My attacks will be more lethal and my power will reach lvl 10 planetary level.

I will put my plans in motion as I reach that level. For solar system level one would need a planet core or chakra fruit or Power like Otsutsuki.

For me that's not necessary as I am a divine tree itself. I changed my appearance but at the core I am still the divine tree.

I only need time, maybe 100 or even 1000 years. Who knows, I am a tailed beast with limits unike the time with Kaguya. 

But once I succeed then no one on this planet will be a match even Kaguya. She is at the same level that I will be but forcefully absorbing and merging with chakra fruit made her lose control,  power without proper control is never good.
