Naruto: I am Naruto's uncle

"Hiccup..."

Sitting cross-legged on the ground and burping slowly, Uzumaki Kyo was very satisfied.

Although the process was difficult, the ending was sweet. In the past few decades, Uzumaki Kyo had never worked so hard for a meal.

Uzumaki Kyo is now completely ignorant of what is happening in the outside world. For the time being, he has "two years" to practice in the Spirit and Time Room.

"Now that we've eaten, it's time to get down to business."

After straightening his body and straightening his back against gravity, Uzumaki Kyo sat up on the ground and meditated.

"Theoretically, I have two years here."

"There is no way to fight against this kind of gravity right now, and exercise is basically impossible. It seems that the only option is to meditate for the time being."

There weren't many choices. Now, Uzumaki Kyo's muscles all over his body were trembling slightly. It was difficult just to fight against gravity, so how could he make any exercise plan.

You can only meditate to adapt to gravity while recovering from muscle damage.

"Hey... in this case... is it possible..."

Thinking of recovering from physical damage, Uzumaki Kyo suddenly had another idea in his mind.

"What would happen if I integrated chakra into my muscles while repairing my body?"

Medical Ninjutsu can stimulate cells through the use of chakra and promote cell division to achieve healing effects.

So if you refine chakra and inject it into muscle tissue, can you make your body stronger?

In the days before this, Uzumaki Kyo had many ideas, but basically did not have the time or conditions to test them.

But things are different now. In two years, I can allocate and exercise freely. Many exercise techniques that I wanted to try before can be tried one by one.

"Hey hey hey, why don't I take off now?"

Feeling happy in his heart, he started drying his hands immediately. Looking at his thigh, which was the most severely damaged part at present, Uzumaki Kyo directly concentrated his chakra there.

"First condense, then refine."

If the Rasengan has very high requirements for chakra stability and control, Uzumaki Kyo's current topic requires much higher chakra control.

To practice the Rasengan, the chakra is required to maintain a stable spherical shape and rotate, and to continuously increase the intensity.

The task of Uzumaki Kyo is to condense chakra, compress and refine it, and then inject it into muscle tissue. There is no doubt that the difficulty is much higher than practicing Rasengan.

"Try refining first."

Feeling the thin layer of chakra condensed on his thighs, Uzumaki Kyo tried to knead that layer of chakra together, fuse and compress it, and change the density of the chakra.

"Gan, it's a bit difficult..."

Under normal circumstances, the process of using ninjutsu is nothing more than condensing chakra first, and then running the chakra to perform it in a specific energy circuit. When the chakra flow is completed, the ninjutsu can be released.

It's the same reason that current passing through a specific circuit board can turn on a specific machine.

But it is not easy to fuse and compress the current.

Tailed beast jade is a product made by compressing chakra. Simply put, tailed beast jade is a small ball compressed into a huge amount of chakra.

The first step in Uzumaki Kyo's experiment is to compress chakra.

"Let's change it to my hand first..."

There are risks in any experiment, and Uzumaki Kyo doesn't want to fuse something like a tailed beast jade, and if he loses control, his leg will be gone.

Condensing the chakra in his hand again, Uzumaki Kyo began to gather the chakra together bit by bit and began to compress it.

"Steady, steady..."

Thanks to the extensive use of chakra in the past two days, Uzumaki Kyo felt that his level of concentrating chakra was much higher than before.

One hand pinched the other hand, and light blue chakra emerged from the palm bit by bit, and was sucked into the small chakra ball in the center.

It's not that Uzumaki Kyo wants to copy the Rasengan, it's just that the round shape has the best ability to withstand pressure.

I saw that the color of the blue ball in the palm of my hand became darker little by little.

It starts out light blue, turns to sky blue, and then changes to blue again.

And the volume has also become larger than when it was first condensed.

Compressing chakra requires a lot of physical energy. While maintaining stability, he also needs to increase the amount of chakra input appropriately. Uzumaki Kyo is also sweating profusely.

"It's not easy..."

Seeing that the small chakra ball in his hand had gradually grown to the size of a table tennis ball, Uzumaki Kyo was happy but also looked weak. He did not expect that this technique actually required such detailed control.

Really exhausted, Uzumaki Kyo decided to stop and rest for a while while keeping the chakra ball in his hand steady.

Looking carefully at the chakra ball in his hand, he saw that the entire blue ball was smooth, round, crystal clear, and very beautiful.

And the energy contained in it is not low. Not counting the chakra lost by Uzumaki Kyo, the amount of chakra contained in this small chakra ball alone is enough to use ninjutsu like water dragon bombs two or three times.

"The color is still light, it should be able to be compressed..."

As the amount and density of chakra increases, the color of the chakra ball will become darker and darker. Imagine if you compressed all the chakra in your body into a small ball and then let it explode...

"Probably better than Deidara..."

Recalling Deidara's super self-destruction, Uzumaki Kyo felt that if he was strong enough and could compress so much chakra, he should be no worse than Deidara.

"It's not finished yet. It's not time to pick a name. I'll wait until I finish you."

Looking at the chakra ball in his hand, Uzumaki Kyo felt that he might use it often in the future.

"Okay, the compression has been initially completed. It's time to try to see if it can be integrated into the body."

He has not forgotten his original intention. Uzumaki Kyo condensed this chakra ball just to integrate the compressed chakra into his body.

"Huh...for the great cause of scientific research!"

With a silent recitation in his mind, Uzumaki Kyo began to guide the concentrated chakra out of the chakra ball.

In fact, Uzumaki Kyo was also worried at this time. He didn't know what would happen if he injected this concentrated chakra into the muscle tissue. Maybe it would turn into a large muscle... It was hard to say whether it was a mutant monster.

"Let's have a little bit first..."

Feeling really uneasy, he didn't dare to use more than once. He dispensed a small amount of chakra, and Uzumaki Kyo guided it towards his thigh.

"Fuck!"

The moment the chakra droplets touched his thigh, an unbearable itching feeling rushed into Uzumaki Kyo's heart!

At this time, Uzumaki Jing thought of the martial arts novels he had read in his previous life.

It seems that I was hit by the life and death talisman of the mountain child that day. If I don’t take the antidote, I will be urinary!

Itching is not like pain. If you really can't stand the pain, your brain will trip, you will faint, and you won't feel the pain anymore.

But itching is different. This thing has no trip protection at all.

Looking down, Uzumaki Kyo could even see that his thighs were turning red at a speed visible to the naked eye, and blood began to ooze from some places.
