Airplanes!

Yang Jin mobilized his whole body's qi and blood, adjusted his breath, and began to slowly adjust his sonic power frequency according to the method of performing the sound skill of Crane Jiuxiao.

He first activated his qi and blood, and then mobilized his dantian qi from his qi and blood, and began to emit a slight buzzing sound or breathing sound from his throat.

Phew! Phew!

As he continued to urge his qi and blood to agitate his breath, the sound of cranes singing from his mouth became more and more sharp.

The entire cave is like a confined space, and the sound waves emitted by Yang Jin reverberate endlessly in this confined cave.

And what he wanted now was this effect, and even increased the intensity and frequency of the crane nine skies, and the sound wave power emitted became more and more dense and sharp.

Phew! Phew!

In the end, the entire hermetic cave almost became a single sound, and the sharp sound of cranes echoed everywhere, shaking the surrounding rock walls and falling rocks.

And with the continuous sound of crane chirping in his mouth, Yang Jin's body was also trembling slightly.

In the end, even the skin, muscles, and bone meridians were trembling regularly with the sound of cranes coming out of his mouth.

Yang Jin's current situation is obviously with the help of sound waves that are emitted and then reflected back, plus the sound waves emitted from his mouth.

Through the amplitude of the inside and outside of the sound waves, so as to achieve the combination of two tones, enhance the magical effect of the power of the sound wave to temper the strength of the body.

His magical idea, which is similar to the combination of two tones and the amplification of sound waves to each other, was the one that came to his mind with a flash of inspiration when he heard the echo of the small stone hitting the stone wall just now.

He first emitted a specific sound wave through the "Crane Screaming Nine Skies" sound wave power, and the sound waves emitted echoed to achieve the same frequency and amplitude with each other.

Then slowly adjust the vibration frequency of the body so that the vibration frequency of the body is also consistent with the vibration frequency of the sound wave power in his mouth.

In this way, with the help of the internal and external pinching vibration of sonic wave power, the body is constantly tempered, so as to enhance the body's defense and toughness.

At the beginning, the frequency and amplitude of Yang Jin's vibration were consistent with the sound wave power emitted from his mouth.

However, when the cave was tightly closed, the sound reverberated so that the entire cave was filled with the sound of cranes chirping continuously.

Yang Jin, who was standing in the middle of the cave, trembled all over, and the frequency and amplitude of his tremors became a little chaotic.

Especially when the intensity of the sound wave power emitted from his mouth reached its highest, his whole body became trembling as if he had been electrocuted due to the anti-shock power of the sound wave power he exerted and the impact of the sound wave power that reverberated continuously in the cave.

However, although his body trembled and trembled, this chaotic sonic vibration method seemed to be more effective in refining his body.

As he continued to urge the qi and blood of his body to emit sound wave gong, his body had been passively tempered under the vibration and impact of sound wave gong.

Especially under the impact of the reverberating sonic power in the cave, the reverberating sonic power in the cave was like a sledgehammer constantly tempering and forging steel.

Yang Jin's entire body trembled wildly as if it had been electrified, and his bones and internal organs were all numb.

In the darkness, Yang Jin's eyes suddenly lit up, and he used all his strength to exert his qi and blood, and in this closed cave, he performed the sound skill of the crane and the nine clouds.

I used all my strength to open the power of this sonic skill to the maximum.

Phew! Phew! Phew! Phew!

The extremely sharp sound of cranes echoed throughout the cave, and at the same time, invisible sound waves carried an indescribable force and slammed into his body densely.

Then it shakes the whole body, and then spreads to every subtle part of the body.

In just an instant, the pores of his whole body were stretched, and the muscles, bones, muscles, and even organs and internal organs of his body began to tremble and tremble under the pressure of this infinite and huge force!

There are not many impurities in the body, and they are also discharged with the operation of qi and blood in the body!

The power of the red sun that was originally absorbed from Mei Yingxue's blood and stirred up in the blood was boiling under the impact and vibration of the sonic power.

With the operation and penetration of qi and blood in all parts of the body, these innate red yang powers that have been purified and condensed by the Hundred Poisons Golden Silkworm Gu and the Golden Guan Jade Lock Technique.

Under the shock and impact of the sound wave power that reverberates in all directions, it is slowly penetrated into all parts of the body to digest and absorb.

Those impurities that existed in the body, which were not much, were also slowly shaken out of the body by the concussive power of the sonic power!

Yang Jin is now under the impact and shock of the sound wave gong, and his whole body is like cutting hair and washing the marrow, and the whole body and outside are vibrating!

Affected by the constant impact and vibration of the internal and external sound waves, he was like an overelectricity, and the oily dirt that had not appeared for a long time slowly discharged from the skin that was constantly shaking and shaking.

Yang Jin just wanted to perform the sound skill of Crane Jiuxiao here, just to verify how effective he was in using the sound wave skill to impact the refining body inside and outside in a flash of inspiration.

In particular, I want to try the effect of the impact and vibration of all the inside and outside of the body.

Is it better than his previous one, simply using the power of the shock that produces the aftermath after performing the sound wave skill of the crane and the nine clouds, and the effect of refining the body from the inside out?

This cave is tightly enclosed, like an impermeable iron barrel, and extremely hidden and safe, which is an excellent place for experiments.

That's why he had a flash of inspiration, and he couldn't help but show the beginner's sonic skill quenching here.

Practice has proved that the effect is indeed very good, at least it is much better than simply relying on the aftermath of the sound skill of the crane and the nine heavens to refine the body. Even several times stronger!

However, now Yang Jin's physical strength has not been tempered to the extreme, so he can't maintain such a high-intensity internal and external sonic impact refining body all the time.

Therefore, he could only gradually raise his voice, and after exerting the sound wave gong to the maximum power, which could only last for a period of time, he felt that his body could not bear it.

Then gradually decrease, then lower to a certain extent, then gradually increase, and repeat the process over and over again.

Yang Jin was bathed in the impact of the roaring sonic power, the mist around his body was steaming, and the sweat was condensed into mist like scorching water vapor, but he was torn apart by the extremely powerful sonic power.

Now his mind is empty, and he seems to have fallen into a state of epiphany that seems to be intentional or unintentional.

His body and mind seemed to be separated at this moment, and all the essences of the five-rank sound skill of the Nine Heavens kept flashing in his mind.

Not only does he have the sonic skill of Crane Jiuxiao, but he also got it from Lu Xinglie, the "Soul Chasing Soul in Bloody Clothes", and read the "Seven Evil Soul Chasing Sounds".

And the last time in the epiphany, by chance, the set of Miaoyin Valley's Zhengu mastery "Miaoyin Heavenly Sound Dafa" that he got from the pair of cold jade ice silk gloves he carried with him also kept flashing in his mind.

Although his mind was in an epiphany, his body was still automatically breathing and lifting his qi, and the qi and blood in his body were also running on his own, and he continued to exert the sound wave skill of the crane and the nine heavens from his mouth with his breath.

And the internal cultivation method of the Three Treasures Arhat Fist, which has been running endlessly inside his body, is also under the constant impact of the sound wave gong, coagulation and quenching the body, refining himself and building a foundation!

Phew! Phew!

And as he entered the state of epiphany, he continued to comprehend and comprehend the essence of the five-grade sound skill of the Nine Heavens.

and the continuous comprehension and understanding of the "Seven Evil Soul Chasing Sounds" and the "Wonderful Sound of Heavenly Sounds", two of the most subtle sound waves among the two realms of righteousness and demons.

The sound of the crane that Yang Jin cast became more and more sharp and high-pitched, and the penetrating destructive power in the sound waves became more and more powerful, and his body was more and more vibrated by the impact of the sound wave power.

If anyone could see through the dark through the sonic clouds, the subtleties of his body.

It will be found that Yang Jin's body seems to be spontaneously adjusting and operating in the impact and collision of sonic power.

Slowly but visibly, the internal organs of the body are transforming towards a more perfect state!

His muscles, bones, skin, flesh, blood, marrow, meridians and organs are extremely cooperative, fine-tuning in this state.

With the assistance of the Crane Jiuxiao's mastery of sound skills, Yang Jin's long hair was flying, and his entire body was trembling in an extremely strange rhythm.

His whole body's muscles, bones, skin, flesh, viscera, blood, and even spirit were all under the shock of this crane and nine heavens sound wave gong, and there was a tendency to gradually merge!
