"Boom!"

A huge roar resounded throughout the solar system. Pen ~ fun ~ pavilion www.biquge.info

That's right, the starry sky in the cosmic environment is vacuum, and without air, it is naturally impossible to transmit sound in the traditional sense.

However, sound itself is only a mechanical wave that travels through a medium due to the vibration of an object.

This mechanical wave is transmitted to the human cochlea, which decodes the vibration and transcodes the signals that the human nerve can recognize, thus forming the sound that the person hears.

However, in high-level civilizations, the definition of sound is much broader than just mechanical waves.

In addition to ordinary sounds, which propagate through mechanical waves, there are also electromagnetic sounds that propagate through electromagnetic waves.

Because electromagnetic waves have a dynamic electromagnetic field, the changing electric field produces a changing magnetic field, and the changing magnetic field produces a changing electric field, and the electromagnetic wave constantly paves itself through the overlapping of these two fields, so that it can propagate in a medium-free environment such as a vacuum environment.

Generally speaking, the sound of nature cannot be propagated by electromagnetic waves, but can only be propagated by mechanical waves, which is called mechanical sound.

However, certain special high-energy collisions produce electromagnetic sound, which is a sound that can be propagated by electromagnetic waves.

Electromagnetic sound, in the form of a special electromagnetic wave, can propagate in a vacuum, and after reaching the matter, it converts the electromagnetic energy into mechanical energy, vibrating the matter, and converting the electromagnetic wave into a mechanical wave.

If the human ear receives this special electromagnetic wave, the cochlea will also be vibrated by this electromagnetic wave, so that it can "hear" this electromagnetic sound propagating in a vacuum.

At this time, when tens of millions of white energy cannons and hundreds of millions of infinitely black abyssal meteorites slammed together.

A terrifying storm of energy spread towards this solar system in an instant.

"Boom, boom!"

Such a high-level energy collision instantly produced countless electromagnetic sounds containing huge energy!

These electromagnetic sounds, in the form of electromagnetic waves, propagate in a vacuum.

Compared to mechanical sounds, electromagnetic sounds are a more advanced type of sound.

Mechanical sound, which needs to be transmitted by a medium, is not fast, for example, the speed in the air can only reach 340 m/s.

Compared to the propagation speed of mechanical sound, electromagnetic sound can travel at the speed of light in a vacuum in the form of electromagnetic waves.

So almost in an instant, an incomparably shocking roar resounded throughout the battlefield!

"Boom, boom!"

A series of violent explosions sounded one after another.

The huge firelight completely enveloped the entire battlefield, and all kinds of fireworks, hundreds of millions of fireworks bloomed in the solar system!

However, soon, in the next moment, from the huge firelight, one after another abyssal meteorites contaminated with infinite pitch black color emerged from the huge firelight, although the number of meteorites that could finally break out of the Empire's thousands of cannons to gather fire was not much, but there were still millions of them left.

The power of the imperial cannon is naturally incomparable, but the power of these abyssal meteorites is also not to be underestimated, plus the number of them is extremely large, reaching hundreds of millions, and the number of artillery fires in this wave of the empire is more than 10 million.

Although each Imperial Origin Cannon, it can explode three or four Abyssal Meteorites.

But in the end, millions of abyssal meteorites broke through the encirclement and struck towards the Imperial fleet group.

These remnants of abyssal meteorites, although menacing, are also dilapidated.

The Empire's Primal Energy Cannon's performance, extreme cooldown time, and extremely fast reload speed, as long as you want, you can quickly activate the second round of fire, and easily blow up all these millions of abyssal meteorites.

However, in the face of the destruction-level abyss, General Feng Zi knew the importance of saving as much as possible, if he didn't care about the consumption of the original energy and attacked unscrupulously as soon as he came up, it was estimated that he would not last more than 10 minutes, and he would have to burp.

Although Feng Zi is nicknamed "Crazy General", he is not stupid, and he is even very shrewd when he fights, which is a commanding instinct.

Therefore, after the first wave of concentrated fire knocked out most of the abyssal meteorites, General Feng Zi stared at the dense invisible fluctuations in front of the meteorite!

"A concentrated burst of high-density electromagnetic sound has been detected!"

"The energy scale of this wave of electromagnetic sound has reached 10 Void Might!" The correspondent shouted in the psychic network.

"Excellent! What I'm waiting for is this wave of electromagnetic sound! Feng Zi waved his hand and ordered, "I order, immediately unfold the Origin Energy Echo Wall!" ”

After Feng Zi gave an order.

In the void below the fleet, suddenly a burst of information light flickered and stacked, and from the light, one after another, huge smooth arc-shaped mirrors were created out of nothing. This is the Empire's best Void Information - Material Transformation Technology, as long as you have the information, you can create everything!

This sound bar, an arc-shaped mirror is the size of the surface of the moon, dozens of mirrors of this size, with a special arrangement of the square, the mirror face is aimed directly below!

In the ultra-high-energy collision of the Imperial Origin Cannon and the Abyssal Meteorite, a lot of dense electromagnetic sounds were born.

Electromagnetic sound has a characteristic that the density of energy contained is much higher than that of mechanical sound, and the amount of energy carried by electromagnetic sound depends on the source of electromagnetic sound.

And through the ultra-high-energy collision of the Origin Cannon and the Abyssal Meteorite, the countless electromagnetic sounds produced naturally carried extremely terrifying energy.

After the Imperial Test, the amount of energy carried by these electromagnetic sounds has reached 10 Void Might!

Void Power and Abyssal Power are units of measurement used by the Empire to measure the power of Void-level energy.

1 Void Power = 1 Abyss Power. If it is the power generated by the abyssal energy, it will be measured by the abyssal power, and if it is the power generated by the energy of the void order system, it will be measured by the void power.

Electromagnetic sound is a product of order, so it is measured by the power of the void.

The abyss power carried by the hundreds of millions of meteorites before reached 100 units, and after the ultra-high-energy explosion, the energy scale carried by these electromagnetic sounds reached 10 void power, which is equivalent to 1/10 of the previous hundreds of millions of meteorites, and equivalent to the power of tens of millions of meteorites!

And these high-level energy complexes, once emitted, are advancing at the speed of light, which is twice as fast as those meteorite groups that advance at 50% of the speed of light.

At this time, a dense electromagnetic sound wave group equivalent to the power of tens of thousands of abyssal meteorites took the lead in rushing towards that side of the Origin Energy Echo Wall!

"The Origin Echo Field unfolds!"

Suddenly, dozens of mirrors unfolded in all directions, and finally connected together, tightly wrapping the entire fleet group.

In an instant, the electromagnetic sound wave group bombarded the materialized echo wall and the energetic echo field in all directions!

There was no splendid scene, and these electromagnetic sounds containing terrifying energy fluctuations were all reflected back silently.

As if it were a real echo, it slammed into the meteorite swarm head-on.

Originally, both were extremely fast, and the distance on the field was also very short at this time, a distance of 10,000 kilometers back and forth.

In less than 0.1 seconds, the electromagnetic sound wave group was violently bombarded with millions of abyssal meteorites.

The electromagnetic sound wave complex is a large area of AOE damage, which is just right to deal with these abyssal meteorites.

The terrifying energy storm swept in all directions, and after the final overflow dissipated, there was no abyssal meteorite to be found on the field.

General Feng Zi used the characteristics of electromagnetic sound wave swarms to finally save a round of concentrated fire to repel this terrifying wave of hundreds of millions of meteorite bombardment.

Just when General Feng Zi was about to launch a counterattack in one go.

A communication reached the bridge.

"Captain! There is an emergency communication insertion, it is Ye Yu's, Ye Yu's communication request sent on the earth!"

(Additional note: I think that a battlefield without sound rendering always feels very unatmospheric.) I don't want to write about a silent battlefield, and I don't want to be sprayed with no scientific knowledge, and I don't know that a vacuum can't transmit sound. So this chapter explains the setting of the book about electromagnetic sound. Later, the setting of this electromagnetic sound will be expanded, so let's explain it first. ）
