Artifact

Dogs can hear sounds in excess of 40 kHz, with an upper limit of about 50,000 Hz, compared to humans, the primate ear can only receive sound waves at frequencies of 20 Hz to 20,000 Hz (20 kHz), and the upper limit decreases with age.

Cats, on the other hand, are more sensitive than dogs, and can pick up sounds in the range of 60 to 65,000 Hz, while bats have an auditory sensing range of 1,000 to 120,000 Hz.

In other words, since the birth of the universe, humans have evolved to the present, and most of the sounds in nature are unheard of by humans.

Whether it is the creation of man by the ancient gods or the evolution of nature, it is not for nothing that human beings can only hear such a small number of pitiful sounds, one of which is because some voices are "deliberately" shaped by an invisible force to be inaudible.

This "deliberately", some of which are well-intentioned and some are malicious, is probably what the ancients called "Jedi to Heaven".

Heaven and man are at war, and if mortals on earth can hear it, then I am afraid that in an instant, the world will be full of deaf people.

Why? Because the human eardrum simply can't withstand such terrible sound frequencies.

However, some people with special physique can hear inexplicable whispers in the dead of night, even in a noisy environment, like the voice of the devil, and like a good temptation.

This is a sound that cannot be heard by others, not even cats and dogs, but only by "special" and "chosen people" - some people are "enchanted" by it, and many more go crazy and commit suicide, and Night Thirteen has seen countless such patients in his years in the madhouse.

I

have written so much above, not because the author wants to make up the number of words, but to tell you a living reality: existence is the opposite of reasonableness, not "if it does not exist, it is unreasonable", and the so-called "non-existence" is just something that cannot be experienced by one's own "five senses" at all in the poor scientific and technological civilization of human beings and such a low level of evolution.

There

are many records of non-existent voices in the world, and one of the more famous and convincing examples can be found in the proclamation of the holy city of Gantivan in January 1999 and the subsequent revision of the exorcism outline.

The so-called people, the so-called ghosts, and the so-called monks are the same as all things in the world, and the reason for this must be a way to solve the confusion of the world, which is the same for the current You Long'er.

It's just that even she herself at the center of the vortex doesn't understand how she manipulates, how she releases, and even how she stops.

Now, what comes out of the mouth of the dragon is the strongest dragon roar, its vibration frequency can sense everything, everything in the mortal world will collapse when touched, even the mountains, rivers, lakes and seas will be flattened in an instant!

Just to hear a "buzz" sound, for all creatures with ears, I saw a cloud hole appear in the middle of the air, and a brilliant pillar of sunlight suddenly fell from the sky that was still surrounded by dark clouds!

In the next breath, it was as if the cloud cave generated an infinite suction, and the black clouds around it rolled and circled in an instant, and they were completely taken away by this terrible impact, and disappeared without a trace!

Look at the behemoth in front of You Long'er again...... No, that can no longer be called a behemoth, but an "empty" behemoth!

A huge cone-shaped hole with a diameter of more than three hundred zhang appeared in the monster's body, and everything inside had been wiped out in an instant, and there was no scum left!

The bottom stopped rising, and the weird big guy straightened up for half a minute, and then it seemed like an irrepressible collapse, accompanied by a series of rumbling sounds, and fell back into the pit!

The monsters looked in, only to see that the monster fell and then turned into pieces, even if it was not hit by the dragon's roar, the remaining surviving giant trees quickly withered and withered, as if all their vitality was sucked away by something, and in a moment a "gray spot" appeared in the middle of the green plain.

After You Long'er did all this, she woke up like a dream, she stared blankly at everything in front of her, and then looked at the empty palms, suddenly felt a nausea in her chest, and hurriedly lay down and retched.

There was a rumbling sound behind him, and the thousand demon beasts cautiously bypassed You Long'er and hurriedly ran forward.

It looks like they are trying to catch up with the big army, but in fact, these demon beasts with low intelligence know in their hearts - a monstrous power emanating from the dragon immortal is like swallowing the sky again, and all the demon beasts are out of breath!

And now that the Dragon Immortal has mastered the power of the Red Moon Orb, I'm afraid that even the original Sky Swallowing Overlord won't be able to hold her!

The demon beasts quickly walked away, and the last few stopped in the distance, looking back at You Long'er, as if to guide her.

In fact, You Long'er didn't vomit anything, but he felt uncomfortable at the thought of swallowing a strange thing.

You Long'er vomited for a while, got up, and admired his "masterpiece" while hurrying, and couldn't help but be secretly surprised in his heart.

The Akatsuki Orb is really extraordinary!

Fang Cai didn't move much at all, just attacked by instinct, but he didn't expect the orb to launch on its own, absorbing an indescribable substance around it, and then Long Xiao broke through the limit and turned into a dragon roar.

Even in the memory of the Yin Dragon, there are a few real dragons that can perform a dragon roar, but I have never heard of a half-human and half-dragon guy who can also make a dragon roar!

You Long'er now believes more and more that the Red Moon Orb is not a monster devouring the sky at all.

Thinking that Yan Yun's body fell into the hands of the demon beast devouring the sky, could it really be as he had guessed before, the Red Moon Orb would be a part of Yan Yun's body?

You Long'er didn't dare to think about it, because there were too many possibilities, if the Red Moon Orb belonged to Yan Yun's thing, wouldn't it be equivalent to robbing Honglian's treasure?

In case Hong Lian suddenly appears one day, she will turn the world upside down with her skills!

You Long'er was thinking and hurrying away, and accidentally saw the last demon beast in front of him who led the way with an imperceptible murderous aura.

This murderous aura was not aimed at You Long'er, but at the corpse of the huge monster, You Long'er looked back and saw a strange scene

Originally, this place, like the surrounding area, was a lush green forest of giant trees, but after You Long'er used the dragon roar to blow off several giant trees, the big guy in the ground appeared, and now it was hollowed out by a blow of the dragon's roar, whether it was the stratum maintained by its root system, the rocks, the sand and mud, or the giant wood forest on the ground, all fell into the big pit where it once stood.

Now, from all sides of the pit, about two to three hundred feet underground, a large amount of black mud is rising like a spring, rising rapidly, and gradually submerging everything.

The strange thing is that in the black mud, there is a large amount of white and thin things wriggling in it, as if it is devouring something.

You Long'er saw clearly, aren't these the roots of the super monster? Could it be that it is not dead?

She was a little flustered, and quietly stopped and observed, only to find some clues.

These roots that are active in the black mud come from all directions, and if I need the most perfect explanation, it means that there are actually these super monsters all around, and they are now taking over the territory of the dead!

Thinking of this, You Long'er suddenly had some bad premonitions inexplicably, she immediately stood still, and shouted at the demon beast waiting for her at the end of the team:

"Give me orders! Stand by the whole army! Stop advancing!"
