"Hiccup..."

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

Although the process is difficult, the ending is sweet, and in the past few decades, Uzumaki Kyo has never spent so much effort to eat a meal.

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

"When you're full, it's time to get down to business."

Straightening his body and straightening his waist against gravity, Uzumaki sat up on the ground.

"Theoretically, I'm here for two years."

"There's no way to fight against this gravity now, and it's basically impossible to exercise, so it seems that I can only meditate for the time being."

There are not too many choices, now Uzumaki Jing, the muscles of his whole body are trembling slightly, it is difficult to fight against gravity, how can he do any exercise plan.

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

"Huh... This situation: Can you..."

Thinking of recovering from his body damage, Uzumaki Kyo suddenly had another thought in his heart.

"What if I incorporated chakra into my muscles while repairing my body?"

Medical ninjutsu can use chakra to stimulate cells and cause them to divide faster to achieve a healing effect.

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

In the days before that, Uzumaki Kyo had also had a lot of ideas, but basically he didn't have the time and conditions to experiment.

But now it's different, for two years, I can freely distribute and exercise, and many of the exercises I wanted to try before can be tried one by one.

"Hey, hey, I'm not going to take off yet, am I?"

With a feeling of beauty in his heart, his hands immediately dried, and he looked at his thighs, which were the most severely damaged parts of his body at present, and Uzumaki Jing directly condensed Chakra.

"Condense first, then refine."

If the Spiral Pill has very high requirements for the stability and control of Chakra, the subject of Uzumaki Kyo at this time has much higher requirements for the control of Chakra.

To cultivate the Spiral Pill, what is required is that Chakra should maintain a stable spherical shape for rotation and constantly improve its strength.

And Uzumaki Jing's task is to condense the chakra, compress and refine the chakra, and then inject it into the muscle tissue, there is no doubt that the difficulty is much higher than cultivating the spiral pill.

"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, 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 the chakra first, and then running the chakra to cast it in a specific energy circuit, and when the chakra flow is completed, the ninjutsu can be released.

It's the same as when an electric current is passed through a specific circuit board to turn on a specific machine.

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

Tailed Beast Jade is the product of compressed chakra, simply put, Tailed Beast Jade is a small round ball compressed into a huge amount of chakra.

The first step in Uzumaki's experiment was to compress the chakra.

"Let's switch to our hands first."

Any experiment is risky, and Uzumaki Jing doesn't want to fuse something like Tailed Beast Jade by himself, and if he gets out of control, his leg will be gone.

Reconcentrating the chakra in his hand, Uzumaki Kyo began to gather the chakra together little by little, and began to compress it.

"Steady, steady..."

Thanks to the large amount of chakra used in the past two days, Uzumaki Kyo felt that his level of condensing chakra was much higher than before.

One hand pinched the other, and the pale blue chakra emerged from the palm of the hand little by little, and was sucked into the chakra ball in the center.

It's not that Uzumaki Kyo wants to copy the Spiral Pill here, it's just that the round shape has the best ability to resist pressure.

I saw that the color of the blue ball in the palm of my hand became deeper and deeper.

From light blue at the beginning, it turns sky blue, and then it transforms into blue.

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

"Drink... Drink..."

The physical exertion of compressing chakra is not a lot at all, and while maintaining stability, it is necessary to increase the amount of chakra input appropriately, and Uzumaki Kyo is also sweating profusely.

"It's not easy.."

Seeing that the chakra ball in his hand had gradually risen to the size of a ping-pong ball, Uzumaki Kyo was happy and weak at the same time, he didn't expect that this kind of technique would require such meticulous control.

Tired too much, 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 body was smooth and round, crystal clear, and very beautiful.

And the energy contained in it is not low, not counting the chakra that Uzumaki Jing lost, the amount of chakra contained in this small chakra ball alone is enough to put two or three water dragon bullets that kind of ninjutsu.

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

As the amount and density of chakras increases, the color of the chakra ball will become darker and darker, imagine if you compress all the chakras in your body into a small ball and then make it explode...

"I think it's better than Deidara."

Recalling Deidara's super self-detonation, Uzumaki Kyo felt that if his strength was in place and he could compress so many chakras, he should be no worse than Deidara.

"It's not done yet, it's not time to pick a name, wait until I'm done with you."

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

"Okay, the compression is also preliminarily completed, it's time to see if it can be fused into the body."

He didn't forget his original intention, and Uzumaki Kyo condensed this chakra ball in order to integrate the compressed chakra into his body.

"Whew. For the great cause of scientific research! ”

With a silent remark in his heart, Uzumaki Kyo began to guide the condensed chakra inside the chakra ball.

In fact, at this time, Uzumaki Kyo was also drumming in his heart, and he didn't know what would happen if he infused this concentrated chakra into the muscle tissue, and if he didn't know it, it would become a major muscle... It's hard to say about mutants.

"Let's start a little bit.."

I really didn't feel at ease, so I didn't dare to use it too much at once, so I divided a drop of chakra a little, and Uzumaki Jing guided it and sent it to his thigh.

"it!"

The moment the chakra droplets touched his thighs, a strange itchy and unbearable feeling rushed to 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 charm of the mountain boy that day, and if I don't take the antidote, it is this urine!

Itching is not like pain, it hurts, you can't stand it, your brain will trip, you will faint, you won't feel pain.

But the itch is different, this thing, there is no such thing as trip protection at all.

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