A loud cry burst out—
Strictly speaking, this is not a sound, but a "sound wave".
The frequency of sound waves that can be received by the human ear is about 20 to 20,000 Hz, and this range varies slightly with different physiological conditions, but generally it will not exceed this range.
For the vast majority of humans, this voice "doesn't exist".
But not hearing doesn't mean it doesn't exist.
The frequency that many animals can receive is much wider than that of humans, such as dogs, cats, and dolphins. The hearing receiving frequency is even 7 times that of humans. Before the catastrophe, many animals have specific behaviors. The reason is that they receive To some kind of infrasound or ultrasonic waves that humans can't pick up.
The sounds of monsters are just outside the range of humans.
The moment Grandpa was about to be bitten by the monster, the black egg emitted an ultrasonic wave far beyond the range of human hearing! The sound was so terrifying, the sharp teeth hadn't touched Grandpa's scales, the monster that came to pick up the cheap suddenly stopped, and the black liquid suddenly splashed out from its surface, and the liquid quickly turned into black powder , The next second, the monster fell straight from the sky, and the round body quickly shrank into a shriveled disk within three seconds.
Not only this monster, but in the dark, other monsters that were grabbing food suddenly stopped what they were doing, and then died in the next second.
Outside the corridor, the patrolling administrator suddenly collapsed with a pool of vomit hanging from his mouth, and he was instantly unconscious.
Vomiting and fainting are still basic symptoms. 150 meters away, a staff member who was walking in the garden suddenly bleeds from the seven orifices, and her heart stopped, and she fell directly to the ground.
Invisible sound waves penetrated the walls, crossed the layers of trees, and people fell to the ground wherever they reached.
There was no way to resist, and everyone fell.
The middle-aged man who respectfully served his uncle beside the bed was listening intently, but he didn't hear any sound, and he fell to the ground suddenly. live him.
The huge courtyard, which was already quiet enough, became even quieter.
There is no life, no insects and birdsong, dead silence.
It seems... everyone is down.
However, at this moment, a pair of white jade feet suddenly came down,
No, it is inappropriate to describe it as white jade. Those feet are indeed white, but the white ones have no trace of blood. They are not as lustrous as jade, but rather like pale and stiff stones.
The feet landed silently on the carpet, and he stood up.
His slender fingers that were as pale as his feet gently lifted the bed curtain, revealing a pale and thin face behind him.
Glancing at the middle-aged man lying on the ground, the man stepped over his body and walked towards the door.
A gray-brown sparrow lay quietly on the long wooden corridor outside the door, motionless.
He passed a few people who fell to the ground one after another.
Without any pause in his footsteps, he walked straight towards the southwest corner.
The wreckage of the two helicopters was smoking and scattered on the grass. They should have suddenly fallen from the air and collapsed half of the wall. They did not crash for long. When the man arrived, the damaged propeller of one of the planes was still there. turn.
The squeaking sound is the only sound here now.
It didn't take long before the inertia of the propeller's rotation was finally exhausted, and the final sound disappeared.
Turning a blind eye to the surrounding scenery, the man continued to walk forward. From beginning to end, his footsteps maintained the initial frequency.
Not too fast, not too slow.
Continuing at this pace, he walked straight into the building that was shaded by layers of trees. At the end of the left side, there was a staircase extending downward. The steps were so dense that he could not see the end for a while.
His feet went up the stairs and went down.
When he completely entered the ground, the surrounding air was completely different from that on the ground! Along with the hissing of beasts and the roar of heavy objects hitting the wall, the air seemed to be compressed layer by layer, and the tunnel was filled with a trembling feeling that made one's scalp tingle.
When his feet left the last step and stepped on the flat ground again, the space in front of him split in a blood vessel-like shape, winding into several bottomless roads.
The roar of the beast and the sound of the crash oscillated into his ears from these iron-like "vessels". Among these voices, a shrill baby cry was particularly striking, and after listening for a moment, the man stepped onto the third road on the left.
He took out the key from the man who fainted at the door, and the man opened the door at the end—the cry came from here.
He pushed open the door.
The moment the door was opened, it was as if some kind of time-still magic was lifted: those fine black powders that filled the indoor air, like smoke, fell one after another.
like a black rain.
This black powder was everywhere in the house, but the man was completely unaffected, dressed in white as clean as new.
The stagnant black eyes were aimed straight at a place in the darkness, where the baby's cries came from.
In the darkness, two faint "lights" hovered like a ghost, flat and flat.
The man flipped the switch of the invisible light on the wall, and the black monster hidden in the darkness appeared in front of him.
It was an unusually petite monster, crawling on the body of a monster covered in gray and white bones, and you couldn't even find it if you didn't look carefully.
The cry came from its mouth.
Staring blankly at the little monster, the man picked it up with one hand.
The little monster's claws firmly grasped the scales of the white monster under it, but how could it compete with the man's strength? With the falling of a few pieces of white bone lin, the little monster was forcibly peeled off from the white monster by the man. .
The scarlet mouth opened, and the little monster let out a small scream that only monsters could hear.
At the moment when Bai Huanyan met the man's stagnant black eyes in horror, a few drops of water slowly flowed down the man's wrist and tickled on the man's bare feet.
The water leaked from the strange paper bag wrapped around the little monster.
After carefully identifying the dirty paper object on the waist of the little monster, the man could not believe that it was actually...
A diaper? !
This monster is actually wearing diapers
What could the fluid leaking out of a diaper be, that's-
With a shake of his hand, the man instantly released the little monster in his hand.
It fell to the ground with a bang, and the dirty little monster quickly crawled towards the gray-white monster on the ground again.
Quick and sophisticated, it hid itself under the long hair between the grey-white monster's neck.
