The strong man who came out of the fire shadow

Nowadays, most of Aoki's ninjutsu training is carried out in space, leaving only the last step of real-life practice.

In the outside world, Aoki just reads books and practices physical skills.Because only physical skills cannot be performed in the mental space.

Just because Aoki's physical skills have not improved much, and there is no better training method in the world of Naruto, Aoki has no choice but to think of other methods.

After thinking for a long time, I remembered a cultivation method on Blue Star called Tiger Leopard Sound.

Aoki used to be a young man with martial arts dreams in Blue Star. He also secretly learned various martial arts secrets online. The results were obvious.

But Tiger Leopard Thunder Sound, Aoki feels that in this extraordinary world with chakra, there is still a possibility of research.

According to the memory deep in my mind, the sound of tiger and leopard's thunder and sinews ringing together is nothing more than "training on the outside to strengthen the body on the inside".

Develop the six core cores of the human body, including the spine, shoulders, elbows, ribs, spine, and internal organs.

Among them, the first five are external training of muscles and bones, and the last one is internal strengthening training.

After practicing Kung Fu to a certain level, you have to go inward, that is, invade the internal organs, and use sound to guide it. The sound goes from the inside to the outside, the force from the outside to the inside, and the inside should be combined with the outside.To put it simply, it uses sound to cause vibrations.

Hubao Leiyin is to imitate tigers and leopards, but in reality it is impossible for tigers and leopards to imitate, but cats can be used to simulate cats.

Aoki is currently unsatisfied with his external physical training, so he can only start from the inside, learning how cats use sound to vibrate from the body, drive the body, and practice muscles and internal organs, so he picked up a black cat and came back to experiment, observing and exploring it every day.

As usual, Aoki used the Yin Escape Chakra Sensing Technique to sense Heidou from the outside world. Heidou lay leisurely in Aoki's arms, his tail swaying gently from side to side.

My stomach felt gurgling, and from time to time there was a rhythmic "gurgling" sound.

His body was trembling slightly all the time, shaking like a tuning fork, and there was even a continuous "buzzing" sound.

But this is not enough. Just relying on the sound of the body to vibrate the internal organs and muscles of the whole body is still too slow.

The chakra in his hands converged on the black beans in his arms.Heidou twisted his body uneasily.

"Meow meow"

The voice was uneasy and low, but was calmed down by Aoki.

As the chakra increases, Black Bean's cousin glows with a gleaming light blue halo, and as the chakra combines with the frequency of vibration in Black Bean's body.

The halo on the black bean's surface began to form circles of ripples and spread outward, and the sound on the black bean became clearer and clearer.

"Buzz...buzz...buzz"

Black Bean's body vibrated significantly, with small amplitude and fast frequency, vibrating like a tuning fork.

"Meow...roar"

At this time, Heidou roared, his hair exploded, and he struggled frantically from Aoki's arms.

From what he sensed, Aoki felt a hint of pain from Kurodou and quickly stopped the experiment.

Heidou hurriedly jumped out of Aoki's arms and ran out in a blink of an eye.

Aoki "..."

"After raising it for several months, it's impossible to kill it."

Next comes the first trial.

Enter the spiritual space again, stand on the grass in the space, and adjust your breathing according to the method you have been exploring recently.

"Um……"

"Huh..."

There was a strange sound in the throat. It took a long time to adjust the sound, and then a wriggling movement slowly appeared in the stomach.

The squirming gradually began to spread around.

When Aoki added chakra, the peristalsis gradually became faster and turned into trembling, and the muscles all over his body began to resonate.

As the chakra increases, the vibration becomes more obvious, the speed of the vibration becomes faster and faster, and the amplitude becomes larger and larger. A circle of light blue halo appears on Aoki's whole body.

And as the vibration amplitude increases, the halo spreads around like a wave.

"Squeak...squeak...buzz...buzz"

The speed of vibration formed a double image, and the muscles and bones of the whole body rang together, sounding like a loud bell.

When Aoki's whole body began to twist and deform, Aoki realized that he had lost his temper.

Because it vibrates so fast and has chakra assistance, Aoki is now like a high-speed car without brakes.

Aoki tried his best to control and began to withdraw chakra, but found that chakra had already formed a resonance with his body, and he could not stop automatically extracting chakra from his body.

If Aoki could wake up at this time, he would definitely find that there was an obvious chakra halo in the external body.

"Coax... coax..."

The sound became louder and louder, and Aoki's life seemed like years. As he reached a critical point, Aoki's body in the mental space suddenly stopped.

Then there is a greater distortion and deformation, which is so large that it forms a snake-like shape.

"bang"

Aoki's entire body exploded, and Aoki fainted.

〖Failed〗

Aoki's last thought before fainting.

"Meow meow?!"

In the outside world, Heidou came back again. When he saw Aoki lying on the bed, he screamed a few times in confusion.

Noticing that there was no movement, he climbed onto the bed and licked Aoki's cheek fiercely.

"Meow meow?"

As Aoki's daily chakra feed, Kurodou clearly sensed that something was wrong with Aoki.
