Chapter 70 Cracking the Sonic Attack

In desperation, Wang Daoyuan thought of the physics knowledge he had learned in his previous life.

After all, he is also highly educated. Since junior high school, he has studied sound waves in physics, and he is still studying in college, so he does not know anything about sound waves.

It's just that the laws of this world are not exactly the same as those of the previous life. When he was a child, he also tried to use the chemical knowledge he learned in the previous life to do things, but without exception, he failed.

For example, he once wanted to make thunder charms by generating electricity by generating electricity. As a result, the world cannot generate electricity at all.

In this world of immortal cultivation, it seems that the principles of matter are not the same as in previous lives.

Therefore, he really had no idea whether the knowledge of weakening sound waves he had learned in his previous life could be used in this world. However, there is no other way at this time, only a dead horse can be used as a living horse doctor.

According to the knowledge learned in previous lives, sound transmission needs a medium.

Such as air and water, but the transmission of sound across the medium will lose a lot of energy. The greater the density difference between the two mediums, the more sound energy is lost, and the less energy, the smaller the sound.

For example, someone is riding a horse in the distance, so far that the sound through the air is completely inaudible.

The effect of sound transmission on the ground is better. When the ear is attached to the ground, the sound of horse hooves can be clearly heard, but the sound cannot be heard when the ear is off the ground. This is the transmission of sound from the ground to the air, and it is transmitted across the medium, and the energy is lost. , the sound is too small for the human ear to detect.

As for the specific principle, it has been several years since I graduated from university in my previous life, and twenty years have passed in this life, so I have long forgotten it.

However, it doesn't matter whether you know the principle or not, the important thing is to know how to do it.

If he can condense the spiritual energy and transform it into an entity, he can create a ball of earth to wrap himself around. Unfortunately, there is no such thing as the amulet he refined.

The armor condensed by the earth armor talisman, the golden armor talisman, and the water dragon armor are also in the state of aura, not an entity. The only non-gas that he can condense is water balls.

Wang Daoyuan made up his mind to take a gamble. If it can weaken the sonic attack, then kill this old thing. If it is useless, just use the second-order middle-grade magic symbol to escape.

Run the water spirit power, control the water in the dark river under the feet, and form a water ball. This layer of water ball is not tightly wrapped around the body, and there are some gaps between it and his body.

He was not at ease with a layer of water polo, and once again condensed a larger water polo, wrapped around it.

Between the two layers of water balls, there is a half-foot gap, which is full of water aura.

When the bell is transmitted, it needs to pass through the air, spread to the outer water polo, then spread from the outer water polo to the gap between the two water polo, then spread to the inner water polo, and finally spread to the air between the human and the inner water polo. He can hear.

If this principle is useful, if you cross the medium four times in a row, it is estimated that the bell will reach your ears without a fart.

Wang Daoyuan not only did not step back, but also took a few steps forward, as if he was about to start.

The black-robed old man once again controlled the yellow bell to make a sound.

To be cautious, Wang Daoyuan still took a few big steps back to avoid this principle being invalid, and he was directly hit by the sound wave, and he didn't even have a chance to escape.

The two were only more than ten feet apart, and the bell sounded in an instant.

The outer water polo was shaken by the sound of the bell, and the entire water polo layer seemed to be boiling, while the inner water polo only had small ripples.

The sound reached Wang Daoyuan's ears, just like listening to a bell from dozens of miles away. If you don't listen carefully, you can't hear it at all.

This principle works, and Wang Daoyuan is very happy: "As expected, there is no fart, old boy, wait for Laozi to hack you alive."

Seeing that Wang Daoyuan was not affected by the sound of the bell at all, the black-clothed old man was a little unbelievable. He pushed the yellow bell several times in a row, but it still had no effect.

On the contrary, he continuously activated the magic tool in a short period of time, and his body was subjected to the force of the shock, and he vomited blood.

After a few breaths, Wang Daoyuan had come to him.

The black-robed old man asked in horror, "How could you not be affected by the bell?"

Wang Daoyuan didn't reply, he directly used the water dragon technique, and a water dragon appeared, entangling Huang Zhong.

Shuilong flew towards him with Huang Zhong, he took Huang Zhong and sent it directly to the Lingzhu space.

Even if there is a connection between the black-clothed old man and the magic weapon, but separated by a space, no matter how talented you are, you will not be able to sense the yellow bell, let alone urge it.

After the biggest threat was lifted, Wang Daoyuan dispersed two layers of water polo, and the water dragon technique turned into a water dragon armor again. With the addition of the golden armor talisman and the earth armor talisman, he was not afraid of what the injured old boy could do to himself.

He knew very well that the villain died of the iron rule of talking too much. Although he is a decent person now, he has to keep his hands steady and send this old boy back to the west first.

He took out the Xuanyang Sword, and without saying a word, he slashed with a sword.

The black-robed old man didn't know if he was injured or what. He was terribly weak. He couldn't dodge this simple sword, he only had time to stagger his head.

The sword was hitting his left shoulder.

Although the Xuanyang Sword is not very sharp, it also depends on who it is cutting. It is almost meaningless to cut pythons and crocodiles with rough skin and thick flesh and scales, but cutting this old boy is really like playing.

As soon as the sword went down, the black-robed old man was almost split in half.

Wang Daoyuan did not choose to search for good things on his body. After killing the enemy, he searched on the spot, which was too easy to be plotted against.

The defensive talisman and water dragon armor still remained on his body. He lifted the body of the black-robed old man and wanted to take the storage belt from him.

Suddenly, a spirit beast bag on the waist of the black-robed old man untied itself, and a young loose cultivator ran out of it.

Wang Daoyuan grabbed him and asked, "Who are you? Why are you here?"

This loose cultivator said nothing, turned back to be a hidden weapon, and then turned to run away.

This hidden weapon is the needle-shaped magic weapon that was hidden in the black smoke when the black-robed old man blew black smoke.

The needle hit Wang Daoyuan's earth armor talisman, and the earth armor phantom shook slightly, which was far less powerful than that used by the black-robed old man.

Wang Daoyuan was too lazy to talk nonsense with him, so he chased after him and slashed the back of the loose cultivator with a palm, causing the loose cultivator to faint immediately.

After all, he's just a second-level qi training guy. If he wants to be a demon in his own hands, let's dream.

At this time, the body of the black-robed old man was still in his hands.

Wang Daoyuan directly opened the three spirit beast bags on his corpse, and made sure that no one or monster was hiding inside, so he put the three monster beasts inside, and put them into the spirit bead space together with the storage bag.

Then put the body of the black-robed old man into a storage bag and hang it on the belt.

Huang Zhong was still in the Lingzhu space, and he threw the corpse directly into the Lingzhu space when he was not sure whether the old boy had a backhand.

In case a Loose Cultivator emerges from somewhere, and directly controls Huang Zhong, when Wang Dao Yuan Shen Consciousness enters the space, give him a shot.

When Divine Consciousness probes in, it is attacked by Huang Zhong, which may involve the soul.

Be careful to sail the boat for ten thousand years, even if the winning ticket is in your hands, you have to be firm. It doesn't matter if you are troubled.
