There is no sound at all from the beginning of the video.
It was so quiet that Yun Tuan suspected that she was deaf. She bent her fingers and tapped on the table. She was relieved when she heard a slight tapping sound.
She cut out the weird creatures, converted them into vector images, and enlarged them without loss.
Judging from the body pattern, it should be a deer.
But the tail is higher than the head, and the top of the slender neck is the excretory organ.
There is also a furry bump on its face, which should be its tail.
Yun Tuan looked at it again and again, but still felt that its head and butt were on the wrong side.
Even nuclear radiation may not be able to create such weird creatures.
Later, Jing Yu and Jing He both appeared on the screen. In the night vision camera, their eyes seemed to be covered with a gray-white haze.
They waved to the camera and opened and closed their mouths, but no sound was recorded at all.
It is impossible for Jing to bring a damaged machine. It may be that it is unable to record sound due to the environmental impact.
Two minutes later, Jing Yu frowned again in the picture, seemingly unable to communicate with words.
Everyone started to gesture with their hands, but the expedition team and the Jing brothers obviously had no tacit understanding. They gestured for a long time without understanding what they meant.
So everyone can only follow the previous queue and continue walking deeper into the valley.
...So the video recorder is not malfunctioning, even if you are face to face, you can't hear the sound?
The cloud pressed the pause button and didn't understand - this is a bit strange. Sound cannot propagate in a vacuum, but as long as there is a medium, mechanical waves can pass through. The only difference is the amount of loss.
The expedition team and the two bosses can all breathe while wearing gas masks. For the convenience of movement, no one is connected to bulky oxygen bottles, which proves that there is air in the valley.
There is air but no sound.
Then, the toxic substances filtered out by the gas mask probably have the effect of "sound insulation".
Similar to sound insulation and anti-noise equipment, it can maximize the loss of sound waves during the propagation process. When it is heard by human ears, there is no sound.
It itself may still have a weak, small amount of sound waves propagating out.
Thinking like this, Yun Tuan separated the audio track of the video, and she was surprised to find that the remaining sound waves were not even recorded by high-precision machines.
This video has no sound at all.
What is going on...
Yun Tuan scratched her head and decided to ignore it for now. She looked at it frame by frame and took screenshots of all the strange things in the picture to deal with later.
A group of people walked into the valley and walked out of the valley ten minutes later.
However, in front of us is the entrance to the valley.
Even the marks made by the expedition leader with stones and elastic bands are still there.
There are no traces of editing in the picture, and there are no abnormalities except for a little jitter in the hand-held camera.
They had clearly passed through the valley, taking a straight route without taking any detours, but they returned to the entrance of the valley?
The contents of the following videos are similar. A group of people walked through the valley over and over again, returning to the same place, and their gestures changed from patient at the beginning to irritable.
"I told you, it's a very strange place."
Jinghe's voice suddenly sounded from the left side of the cloud. She was startled and almost jumped up.
"Why did you come over without making a sound?" Yun Tuan took a sip of Liang Baikai and stared at Jing He's face, trying to find any abnormalities.
Jing He waved his hands nonchalantly, "It's not that we didn't come back all night, it's just that... we had a full body checkup in the early morning, including a genetic sequence check, and then we returned to the apartment after making sure there were no abnormalities."
Yun Tuan's brows furrowed when he heard this answer.
"Have you kept the air samples and soil samples over there? Also, have you seen this animal since?"
Yun Tuan asked while placing the enlarged and color-adjusted picture on the computer screen.
