Wu Yuan, as a layman, thought that the instrument that couldn't blow the sound was bad, so he angrily threw the black pipe to the ground, and a well-made black pipe was broken by him!

Huo Chi was angry and hit up, but he was helpless. These guys, it's really hateful. How precious the things dug up from the ruins are, they were actually destroyed by him like this.

However, Huo Chi is also well aware that even in his original world, it is not uncommon for various dynasties to change dynasties, and the destruction of artworks and precious musical instruments caused by foreign invasions.

In an era of war, who can pay attention to the beauty of art except life? If you want to get close to art, you still need an era of peace.

However, Huo Chi thought about it, sometimes fierce conflicts can give birth to new art, but he didn't know what this monster invasion would eventually bring to mankind.

Huo Chi felt sorry for the good things here, but Wu Yuan over there had already begun to let the soldiers play the trumpet.

The loud sound of the trumpet soon filled the square, and although the trumpet played by the soldiers was actually a simpler youth horn, an instrument that could only play four notes, but those who could still play these four notes into a unique composition.

The soldier was actually repeating the wake-up call over and over again, but even this simple tune was the most beautiful tune everybody heard today.

Everyone stopped covering their ears, and the anger in Huo Chi's heart weakened slightly, but the huge monster was unmoved, still moving slowly.

"Okay, okay!" Wu Yuan found that the military horn was completely useless, and angrily ordered the soldiers to stop playing, he looked at the monsters that were still moving, and had no choice but to order the soldiers to continue throwing out the alarm.

However, there are fewer and fewer alarms, and Wu Yuan has to start thinking about the use of vibrating crystal bombs.

"Several, what do you think will be the effect of using a vibrating crystal bullet on him?" Wu Yuan was a little undecided.

"Be cautious when using the vibrating crystal bomb, I heard that a thousand-level monster was mutated into a thousand-person level because of the vibrating crystal bullet a while ago. ”

"I also think we need to be cautious, we can barely control this thing now. ”

I think we have to use a vibrating projectile, at least a fifty percent chance of killing it, and we can bear the other half of the risk. ”

"What can you bear? You should know how important this place is, and if it is destroyed, how will we explain it to the above?"

Several commanders chattered and held their own opinions. Wu Yuan scratched his head, they couldn't come up with a reasonable opinion, this is not a way, what should I do?

The White Eagle side did not want to lose the ruins of this ruin, and this was because there were a large number of frequency reduction oscillators here. Now Wu Yuan deeply suspected that these frequency-reducing vibrators came from this monster, and if he couldn't deal with the problem of the monsters in front of him, those vibrating crystals would not be able to get his hands on them.

However, the risk of using a vibrating bullet is also obvious, and the more powerful the monster, the more obvious the side effects of the vibrating bullet.

Now they can't handle this big guy, and if the vibrillator bounces side effects, this ruin, and even the other ruins, might be finished.

Wu Yuan put his hand on his temple, he seemed to feel that his mechanical head hurt a little, what should he do?

"Throw a few more alarms out!" Wu Yuan asked the soldiers to continue throwing the dismantled alarms while thinking. The beeping alarms flashed red, and although they were able to temporarily stop the monster's rapid movements, they could not last long.

At this moment, Huo Chi, who had been carefully observing the behavior of the monster, suddenly found that a soldier threw the alarm on the body of the ice element, and the monster shook all over his body, strange, it is said that such a small alarm should not have any specific attack power for the monster.

Huo Chi hurriedly looked carefully at the location of the alarm just now, and this time, he saw something more interesting.

Where the alarm hit just now, those hard blue ice crystals actually shattered slightly, and not only that, but the cracked ice crystals also flowed out of some transparent liquid.

The liquid slowly spilled and gradually solidified, and only after resealing and closing the shattered area before the ice element continued to move forward.

Could it be that the sound of the alarm has an actual destructive effect on the monster, and the monster just now caused the surface to crack or even "bleed" due to the close action of the alarm?

In other words, in order to achieve a better effect, the sound of the alarm must be very close to the monster, or even touch the monster.

According to the actual battle of the soldiers just now, it can be seen that the monster doesn't care about physical and chemical attacks, and it is obviously not a physical effect that the alarm smashed on the monster just now and injured it.

Since it is not the physical attack that plays a role, then there is an absolute relationship with the sound. It's just that the effect of simple alarms is limited, even if they throw all the alarms in their hands on the monsters, for such a huge monster, the damage caused is really limited.

A small wound is not able to quickly defeat the ice element, nor can it solve the immediate crisis. In addition, the sound of the alarm is severely distorted when amplified, and it cannot effectively attack monsters.

It would be nice if there was any sound that simulated the sound of an alarm, or that could find the audio range that was really harmful to the alarm sound.

After all, sound is nothing more than sound waves generated by the vibration of objects, and what monsters are really afraid of should be the sound waves themselves.

The essence of sound waves is vibration, and this vibration can trigger resonance with other objects. And the frequency of each object is different, if the frequency of the two objects is close, there is a chance to cause a resonance effect!

Could it be that the sound of the alarm is close to the frequency of the ice crystals on the surface of the monster's body, so that the ice crystals can be shattered?

Huo Chi suddenly realized that he might have figured out the key, no matter how hard things are, they have frequencies, as long as they find the frequency that makes them resonate, they can shatter it!

If that's what he thinks, he just needs to find a way to simulate a certain frequency in the alarm!

No wonder Wu Yuan used various musical instruments to play indiscriminately just now, and if he wanted to achieve the result of resonance, he had to attack the ice element with strong sound waves when the ambient sound was relatively quiet, otherwise it would be playing the piano against the cow, and it would not work at all.

"Abu, is the solution to the ice elemental resonance?" Huo Chi immediately asked Abu for help.

"You won't know if you try it. Abu didn't give a clear answer, but suggested that Huo Chi try it.

"Give it a try?" Huo Chi turned his head to look at the others, but his heart hesitated. He should be able to run away if he fails the test, but what about them? What can they do?
