"The frequency of sound waves? Theoretical soul masters are indeed all partial geniuses, although their own strength is not good, but if they continue to study in a certain direction for a long time, they can always get some results. ”

After yesterday's training, Teacher Xu Maochang took the initiative to communicate with Lin Yueyun, and Lin Yueyun realized that he was able to resist his sonic attack at the beginning, not because of his martial soul characteristics, but because of his research results.

Participating in this training, in addition to the unique skill of retardation, his own goal is actually Lin Yueyun!

Xu Maochang can comprehend that the essence of sound waves is the propagation of the vibration of objects in the medium, and use it, which makes Lin Yueyun very admirable, theoretical soul masters are really geniuses in another aspect, God has closed a door for you, but it will also open a window for you, like these theoretical soul masters, their own cultivation talent is not good, but their understanding and wisdom are beyond ordinary people.

Of course, generally speaking, soul masters don't want to be this type, and what a painful thing it is to have empty understanding but can't do it in person because of the martial soul talent?

It's like giving you a way to make a fortune, but putting you in prison, only to watch the opportunity slip away, or be completed by others, what a grief!

It is easy to see that sound waves are related to vibrations, and it is easy to feel it when you play the piano and beat the drums, but it is not so easy to figure out how to grasp the specific correlation and how often it is.

Although Xu Maochang did research some results, Xu Maochang still has a certain deviation in the specific process.

Sound does not come from the ear canal, the skin and bones of the soul master can also conduct sound, and in order to block out the sound waves completely, they must be completely eliminated before the sound waves can arrive.

It is impossible to completely isolate sound waves with soul power, as long as there is something substantial, sound can be transmitted, and the shield formed by soul power is naturally the same. It's just that some special soul shields counteract the energy contained in the sound waves, which partially resists the sound wave attack.

Note that this is to resist the damage of the sound wave, not to isolate the sound wave itself, just like taking a spear to stab the shield, the shield is not broken, it does not mean that the spear has no attack effect, but the shield defense is above the sharpness of the spear.

The so-called immunity is actually the absolute gap between offense and defense, as people often say, one force breaks ten thousand laws, it is precisely because this power is far superior to the so-called "ten thousand laws", in the face of this power, those relatively weak laws will naturally be broken, and vice versa.

If you want to isolate sound waves, it is not impossible, in a vacuum environment, even in the absence of air, sound waves naturally cannot be transmitted. But there is still a problem, the respective volumes. If it can shatter the sound wave of space, even if it is a vacuum environment, it can launch an offensive, of course, this can no longer be called a sound wave, but a spatial fluctuation. However, since it can create a vacuum environment in the true sense of the word, I am afraid that it must also have the power to break through space.

Although Xu Maochang's ideas were a little off, he still gave Lin Yueyun a lot of inspiration, so that a certain sonic soul technique in Lin Yueyun's idea could be tried in advance. So after Lin Yueyun went back, he carefully combed through the night, sorted out his thoughts, grasped the inspiration, and ran to the back mountain early this morning, ready to ask the empty elder.

Running all the way over, Lin Yueyun stopped to take a look, the sun seemed to rise a little late today, and the sky was still a little dark, but what was the situation with the bright star in the sky?

"Be careful!"

An older generation soul master who was recuperating in the back mountain saw Lin Yueyun approaching and immediately shouted.

Lin Yueyun's intrusion interrupted the strange tranquility of the back mountain, and several figures flew out in an instant in the originally quiet and unusually quiet back mountain.

These older generation soul masters are not relying on flying soul guides, nor are they flying with the help of flying soul skills, but genuine high-level soul masters above the soul saint level!

"Why are you so nervous? I'm not going to do anything to this junior, empty string song, what do you think of my proposal?"

A cold voice came from the air, Lin Yueyun realized that there was a cold figure above the void, take a closer look, the face is a little familiar, corresponding to the star in the sky, I'll go! Lonely Star!

At this moment, Huang Jinxu, the lone star of Tiansha, seemed to be more than ten years younger, Lin Yueyun almost didn't recognize it for a while, and his whole person's momentum has changed dramatically.

The last time I saw the Tiansha Lone Star, tyrannical, ruthless, giving people a feeling of full anger, as if rejecting everything in this world, now it is a lot deeper and more introverted, to describe it, it seems to have found its own belonging, and its heart is no longer cynical.

And facing the Heavenly Evil Lone Star are the elders of the Thousand Souls Academy who are recuperating in the mountains behind. People's life expectancy is limited, these old people, are coming to the end of their lives, most of them do not continue to lead classes to teach students, usually recuperate in the back mountains, have nothing to get together to drink tea, bask in the sun, or guide those geniuses in the academy, but it is also comfortable, can spend their old age here.

The strongest one among them is naturally the empty elder, and in addition to the empty elder, there are two unknown Contra powerhouses!

In Lin Yueyun's cognition, in addition to the empty elder in the academy, the dean Xiang Xiaotian is an eight-ring soul douluo, and at this moment, the eight-ring soul master has directly doubled!

However, one of these two is obviously in worse condition than Kong Lao, and it is estimated that his age has exceeded 100, and it is really hard to say that he can exert several percent of his peak combat power with this body and bones.

The other one is relatively young, Lin Yueyun recalled the relevant information, according to his similar face to the dean, he probably determined his identity, it should be one of the seeds of the Thousand Spirits Academy's impact Title Douluo, Xiang Long, the eldest son of the dean Xiang Xiaotian, is also in his sixties this year, and has not been walking in the outside world, but he didn't expect that he had broken through to the eighty level, and quietly hunted the eighth soul ring!

Facing these two hidden eight-ring soul masters in the academy, Lin Yueyun could only say that the Thousand Souls Academy deserves to be an old academy with a history of thousands of years, so it has to be left behind, right?

Three eight-ring soul masters who are in a good or bad state, seven soul saints, this is the real situation in the mountain behind the Thousand Souls Academy. It is still in a stalemate, and once it starts, Dean Huang and Director Yue Qianshan and others from the academy can also rush over in time.

At that time, there will be four Soul Douluo, more than ten Soul Saints, and more than a number of Soul Emperors can participate in the war, this power should not be underestimated, even if the Title Douluo comes in, it will not be cheap.

In the face of this kind of lineup, Huang Jinxu was quite calm, standing in the air with his hands behind his back, and the eight soul rings behind him had no tendency to be excited, and Lin Yueyun was able to get a glimpse of his soul ring matching.

One yellow, three purple, and four black, this soul ring match is stronger than the best soul ring match, and his second soul ring is already a thousand-year soul ring!

As far as Lin Yueyun knew, Huang Jinxu's martial soul was born in an awakened state, although he cursed the whole family, but his father died suddenly when he was eight years old, so his first soul ring was naturally obtained with the help of his father, and it is unknown what happened after that.

However, Lin Yueyun knew the story of the fourth soul ring, and when Huang Jinxu was about to hunt the fourth soul ring, he bumped into several family soul masters who were hunting the soul ring, and then subconsciously killed the soul beasts that rushed over, which was their goal.

It could have been explained well, after all, his personality was not so extreme at that time, but he preferred it by coincidence, this thousand-year-old soul beast actually burst out of the soul bone!

As we all know, the more powerful the soul beast, the greater the possibility of bursting the soul bone, only a 100,000-year soul beast can stably produce soul bones, it is almost impossible for a hundred-year-old soul beast to produce soul bones, and the probability of a thousand-year soul beast producing soul bones is not large, but it was encountered by Huang Jinxu.

So, the problem is solved.

The value of soul bones is expensive, and the supply exceeds demand, so those family soul masters naturally won't give up, and they don't want to leak the news to arouse the peeps of people with hearts.

And looking at Huang Jinxu, who has just broken through to level 40 and has not yet obtained the fourth soul ring, in order to hunt thousand-year-old soul beasts on his side, there is a soul king, and three soul sects to help, plus the juniors of the family who are waiting to obtain the fourth soul ring, how those family soul masters will choose, it is conceivable.

As a result, Tiansha Lone Star successfully killed the descendants of the big family and obtained a soul bone, but due to strength factors, he couldn't kill people and kill people, so that one of the soul sects could escape.

Then he entered the battle royale environment that he liked to see, whether it was for revenge or for the soul bones, it was impossible for that big family to let Huang Jinxu go, and finally became one of the stepping stones for Tiansha Lone Star to become famous.
