Well, there is a chapter in the morning! There is another chapter in the afternoon, and this chapter is coming to an end, so stay tuned for the first chapter of Journey to the West!

..........................................................................................

This Donghuang Bell is an innate spirit treasure, and the sound from the vibration of the innate spirit treasure is naturally different from the sound made by ordinary things.

Although with Ziwei's current mana, he could only barely urge this Eastern Emperor Bell, but this was enough.

First, this kind of sound has terrifying and incomparably lethality, and second, the lethality of the voice belongs to a differential attack, which does not do any harm to Nandou and Twenty-Eight Su, but for opponents such as Mo Xuan and the Bull Demon King, the lethality is extremely great.

When the first bell entered Mo Xuan's ears, the reaction of the Bull Demon King and the others was the same, a burst of dizziness, and the whole person was shocked like a lightning strike, and the moon-breaking battle skill was too late to be used, so he couldn't move.

Thankfully, Nandou didn't take the opportunity to make a move at this time, because he didn't think it was needed anymore.

After waiting for the bell to end, he directly took off Mo Xuan's head and handed it to Ziwei, which was considered to have completed the task, so he even took back the realm of light, after all, this also requires mana.

Dealing with a monster with the peak strength of the Earth Realm, an opponent who has never broken through the Heavenly Rank, using the Light Realm of the Second Heavenly Rank, and then looking at the effect, he himself felt that he was too careful.

"Beidou is really useless!" he secretly said in his heart, Mo Xuan, who did not use the moon-breaking battle technique, that bit of strength was not uncommon in his eyes, it was just a fast and weird peak master of the earth realm, and using the realm of light to deal with him was really a knife to kill chickens.

It's just that he forgot that killing chickens with a knife sometimes doesn't necessarily mean that he can kill them.

The power of the Eastern Emperor Bell was extremely powerful, and the first bell shook Mo Xuan, and Mo Xuan also began to be a little desperate, he began to urge his Fire Separation Xuan Gong with all his strength, forcibly suppressed the injuries in his body, and when he broke through the realm of light with the moon-breaking combat technique, the realm of light suddenly disappeared, and at the same time, the second bell came.

Mo Xuan, who was originally wrapped in flames because of the full force of the Fire Xuangong, was like being poured a basin of cold water on his head, and the flames in his body were extinguished in an instant.

A strong feeling of dizziness struck again, and as soon as it was dark in front of him, he fell down.

Seeing that Mo Xuan fainted, the cold light flashed in his eyes, and as soon as he raised his hand, he was about to start cutting off Mo Xuan's head, and at the same time, the third bell rang over.

Having said so much, in fact, the time of the three Donghuang bells was very close, and the Ziwei Emperor knocked three times in a row, breaking the apricot yellow flag that Jiang Ziya relied on to protect himself.

"Prime Minister, I haven't seen you for 10,000 years, your old man really surprised me!" The Ziwei Emperor held the East Emperor Bell in his right hand, his face looked a little pale, "Do you think I don't know what kind of mind you are fighting? Do you think that the Bull Demon King and a few of them can bring me down? Do you think that the Jade Emperor guy secretly supports you, I don't know?"

Jiang Ziya coughed up a mouthful of blood, and his face was unusually gray.

"Donghuang Bell, how can it be in your hands!"

"Why can't the Eastern Emperor Bell be in my hand!" Zi smiled, and raised the dark golden bell in his hand demonstratively, "With my mana, although I can only exert the power of this Eastern Emperor Bell, but against you, it is enough, I still have the strength to knock it again, Prime Minister, if you have any last words, just say it, because after I ring the fourth ring, you will never have a chance again......!"

Jiang Ziya smiled miserably, shook his head, and stopped talking, at this time, he was also desperate, he had calculated everything, and the only thing he didn't count was this Donghuang Bell.

"Since that's the case, then let me send the prime minister on the road!" Ziwei saw that Jiang Ziya stopped talking, knowing that he was gone, and he was no longer interested in these tongues, so he smiled slightly, and with a shake of his right hand, he urged Gu to ring the Donghuang Bell again.

When the first bell rang, Mo Xuan was shocked, and when the second bell rang, Mo Xuan completely fainted.

But is it really fainting?

Only Mo Xuan knew that when the second bell rang, he was brought into a mysterious state by this sound.

Sound, yes sound!

What is sound?

What is the nature of sound?

The principles of physics tell us that the so-called sound is produced by vibration, and the vibration of the object is the source of the sound, and the object that emits the vibration is called the sound source.

Since objects vibrate in different ways, the sound produced is also different, and the same sound effect is naturally different.

It's just that, no matter how different it is, the essence is still the same.

Although he hasn't reviewed physics for hundreds of years, Mo Xuan still understands this basic truth.

The vibrations of the air that are moving forward are called sound waves, and the space in which sound waves propagate is called the sound field. When the sound vibration propagates in the air, the space-time temperament point is not taken away, it just vibrates back and forth near the original position, so the propagation of sound refers to the transmission of vibration. If the amplitude of the vibration of the object changes with time like a sinusoidal curve, then this vibration is called simple harmonic vibration, and the surrounding air particles also vibrate when the object is simple harmonic vibration. The distance of the object from the stationary position is called the displacement χ, the maximum displacement is called the amplitude α, the relationship between the displacement of the simple harmonic vibration and the time is expressed as χ = αsin (2πft + φ), where f is the frequency, (2πft + φ) is called the phase angle of the simple harmonic vibration, it is an important physical quantity that determines the motion state of the object, and the amplitude α determines the strength of the sound.

The number of times an object vibrates in a second is called frequency and is measured in hertz (Hz). The more vibrations per second and the higher the frequency, the sharper or more pitched the sound is heard by the human ear. The human ear is not perceptible to vibrations at all frequencies. Generally speaking, the human ear can only hear the sound with a frequency of 20~20000Hz, and the sound in this frequency range is usually called audio sound. The sound below 20Hz is called infrasound, and the sound above 20000Hz is called ultrasound. Neither infrasound nor ultrasound can be heard by the human ear, but there are some animals that can hear it, such as mice that can hear infrasound and bats that can feel ultrasound.

This is what Mo Xuan understands.

But if you just understand the reason, it is not enough, you also need to be capable.

It's like he still knows the principle of the atomic bomb, but if the atomic bomb explodes next to him, he will not die under the nuclear explosion, so it is not enough to understand the principle, but also to have the corresponding ability.

Mo Xuan has this ability, the ability to emit ultrasonic waves from bats makes him have an extremely deep understanding of sound, and after the second bell rings, the ability from bats in Mo Xuan's body begins to play a role, and brings Mo Xuan into a mysterious state.

Time and space vanished in this moment, and the only thing that appeared in front of him was the sound waves.

As someone else, they may think that this is an illusion, this is a return to the light before death, but in Mo Xuan's eyes, these waves are so familiar!

It is the fluctuation of the sound, and it is the fluctuation of the sound produced after the vibration of the Donghuang Bell.

At this most critical moment, Mo Xuan felt this magical, water-like fluctuation.

This is the sound wave produced by the Donghuang Bell!!
