At first, the old queen mother did not believe it, thinking that the palace people were aggrieved by Concubine Zhen and deliberately said these words to scare her. For this, she had several eunuchs beaten to death. It was not until she personally sent her confidants to take a look at the palace wall that she was sure that the palace wall was there. Whenever there is a thunderstorm, the ghost image of Concubine Zhen being dragged away will appear.
In addition, the palace maids and eunuchs who escorted Concubine Zhen all hang themselves into wells out of fear of ghosts, which adds a touch of horror.
The old queen mother herself believed in ghosts and gods. She heard people around her mention the ghost of Concubine Zhen. She immediately felt that Concubine Zhen died unjustly and came to seek revenge from her. In order to eliminate Concubine Zhen's resentment as soon as possible, she ordered the eunuch to kill Concubine Zhen. The body was fished out and buried with great splendor. At the same time, rituals were performed for Concubine Zhen in the palace, hoping that she would be happy as soon as possible.
However, this kind of belated debt is of no use. No matter how many rituals the old queen mother does, as long as it rains and thunders, the ghost of Concubine Zhen will definitely come out to cause trouble.
Later, Deshou Gege, who had returned from studying abroad, came to see the old queen. He found that everyone in the palace was talking about Concubine Zhen's innocent soul. When he mentioned this matter while chatting with the old queen, the old Buddha also looked sad and said frankly that he had It was indeed too much. Girl Zhen just had an unstable temper. She was also angry back then, but she didn't expect that her eunuch would take her seriously.
Although people in the palace were panicked and everyone thought that Concubine Zhen's ghost was causing trouble, in Gege's view, it was not the case.
She had been working in the West with her father since she was a prince. She graduated from a Western school and had received a scientific education. It was difficult for her to believe in ghosts and gods. Gege felt that this incident was indeed bizarre, but it was not necessarily the work of ghosts and gods.
For this reason, she just waited for the thunderstorm to run near the palace wall where the accident happened. After the night, she waited for the ghost of the enemy to appear. On the palace wall, several palace maids and eunuchs appeared. They dragged Concubine Zhen and escorted the ghost away. The people accompanying him were so frightened that they did not dare to exhale loudly.
The emergence of such a situation made Gege do the opposite and boldly walked to the palace wall and carefully observed the ghosts on the palace wall.
This move frightened the palace people who were protecting her. They were all afraid that Concubine Zhen's ghost would harm Princess. They didn't feel relieved until Princess returned safely.
This line of work was a bit dangerous, but it allowed De Shou Gege to see the innocent soul at close range. She was sure that it was not the evil spirit, but she didn’t know what it was. Then she returned to the palace, consulted a lot of information, and consulted Dr. Yang. Only then did we find out the truth about the ghost on the palace wall.
Most of the palace walls in the Forbidden City are vermilion. When craftsmen made the pigments, they would add a large amount of red iron ore to the dye, which caused the palace walls to be covered with a thick layer of iron tetroxide.
These things are simply magnetic magnets and magnets. In addition to being used to absorb iron and stone, they are also excellent materials for making recording and photography equipment.
That year, it was a thunderstorm when Concubine Zhen was dragged away. During the thunder, the lightning was attracted by the magnet on the wall, causing the entire wall to be attracted by lightning. When the lightning was full, it became a simple photography plane.
At this time, the palace maids and eunuchs who happened to be escorting Concubine Zhen passed by this palace wall, and their images were left on this palace wall.
Since photography requires electricity to develop, this wall is no different from other walls at normal times. It was only after the lightning was introduced again that the electricity was re-energized, and the pictures that were accidentally taken that year were projected.
Thunder and lightning, dull red walls, when the ghost of Concubine Zhen appeared in the palace, these palaces became more and more frightened, and regarded these recorded images as ghosts. When everyone saw these things, rumors began to spread. It's spreading like wildfire and can't be stopped.
As for the palace maids and eunuchs who hanged themselves, it was entirely because they saw these ghosts and thought that Concubine Zhen's ghost was unsettled and wanted to take away their lives, so they committed suicide out of fear.
After Deshou Gege told the old queen the truth about her research, in order to completely dispel her doubts, she specially selected a thunderstorm to make a lightning rod for this section of the palace wall. As long as the lightning was introduced to other places, the ghost shadow never appeared again. .
This dispelled the old queen's worries. From then on, this Deshou Gege stayed with the old queen as a female official until she got married.
After finishing this rumor, Song Siyuan looked at the crowd and said: "If the palace wall is hit by lightning, it can turn into a camera. Then it is more normal that we are in the virgin forest and find that these stone pillars can produce noisy ghost voices. Quartzite and Magnets are not the same substance, but they both have the function of recording and recording, which can be realized scientifically."
Yue Guanchao smacked his teeth and said: "The palace walls in the capital appeared ghostly because they were struck by lightning. Then why were these sounds recorded in this forest of pillars? Just like yours, the palace walls are somehow connected. antelope."
Song Siyuan seemed to have predicted something from him and explained: "It's because of the shock!"
She picked up these metal veins: "Just now, I tried to knock the metal. The metal vibrated like a tuning fork and vibrated. These veins are connected to each other. The vibration caused by the ground will make all the metal veins vibrate. When it becomes active, every time the metal trembles, the sound of the vibration will be recorded into the stone. If a marching team appears here, the vibration will intensify and more noisy movements of the march will be recorded. At the same time, because this place used to be a volcanic area , there must be magma layers and geothermal layers underground, changes in the strata occur at any time, and this forest is constantly recording at any time, recording all the sounds of stratigraphic activities into the quartzite."
"At night, after the sun disappears, the ground begins to change from absorbing heat to releasing heat. The rock continues to vibrate the veins in the alternation of hot and cold, releasing the recorded content randomly. Since quartzite is just the original stone, the sound playback is also very large. The randomness and uncertainty make the sounds appear irregularly, which adds to the rumors of ghost whispers."
"If you don't believe it, we can do an experiment."
songs Leaves grooves of varying depths in the stone.
Then the metal veins were removed, and the stone was heated close to the metal veins. The veins continued to vibrate the stone, and the stone indeed began to vibrate rhythmically, exactly the same as Song Siyuan's tapping rhythm just now.
Everyone saw with their own eyes the sound of metal hitting the rocks, and they already believed that what she said was true. However, they still knew nothing about animals being afraid of the canyon.
"Then why are animals afraid of the rocks in the canyon?"
Xu Xiake knew that this problem was related to their continued journey. If animals were afraid of sounds, then their horses might not be able to cross the canyon. Solving this problem was a top priority.
Song Siyuan continued to analyze the current unknown situation: "Animals are not afraid of rocks, let alone canyons, but they are afraid of infrasound waves."
In nature, sounds below 20hz are infrasound waves, sound waves with a frequency of 20hz~20khz are called audible waves, and sound waves with a frequency of 20khz~1ghz are called ultrasonic waves.
The vibration conditions in this valley make it impossible for ultrasonic waves to appear. Normal waves are audible sounds, and only secondary waves are harmful.
Infrasound waves come from a wide range of sources, including tsunamis, ocean storms, meteorite explosions, volcanic eruptions, gunpowder explosions, air turbulence, magnetic storms and auroras, earthquakes and flash floods, galloping carriages and horses, lightning and thunder, rain and rivers, and even butterfly disturbances and animal walking. Produce infrasound waves.
This kind of sound wave travels extremely far and is penetrating. It can easily penetrate gas, ocean, rocks and soil. Even fine steel copper plates, concrete walls, masonry and tiles can easily penetrate. If the sound wave is wide enough, It can also penetrate cars and cruise ships.
Neither humans nor animals can withstand the influence of low-frequency infrasound waves. Short-term exposure to infrasound waves will make animals irritable, irritable, and frightened. Long-term exposure to infrasound waves will directly damage the internal organs and brain of animals, causing serious internal injuries. Deliberately producing ultra-low-frequency and high-power infrasound waves can even directly cause internal bleeding and death of animals.
The generation of infrasound waves is entirely due to the vibration of objects!
These metal veins in the valley will produce low-frequency vibrations under the influence of earthquakes and geothermal heat. That is, when recording on quartzite, the infrasound waves generated by the metal veins will never stop, even at night, as the heat of the soil and rocks And never stopped.
It turns out that the entire valley and the peaks on both sides are constantly generating infrasound waves.
However, the sound waves that the human ear can hear are between 20hz and 20khz. This kind of infrasound wave can neither be heard nor seen by the human ear.
Animals can hear sounds below 20hz. The fear they feel after hearing the sound is incomprehensible to humans. In the ancient context, it is completely understandable to understand animals as fearing the majesty of mountain gods or devils.
For any animal, as long as infrasound waves are produced in nature, there must be disasters such as earthquakes, earthquakes, and rock explosions. They instinctively want to seek advantages and avoid disadvantages, and of course they will stay away from here, no matter what. near.
"In a sense, the people who created the Ghost Whispering Pillar Forest have already noticed these characteristics, so they deliberately created this mysterious phenomenon to keep people and animals away from the valley."
Song Siyuan paused, and finally understood the sound of animals being afraid of the canyon. Everyone thought about it carefully, and realized that this was really the case.
She looked at the surrounding pillar forest: "I guess the infrasound waves generated here are only low-power and can only drive away animals. If they were low-frequency and high-power, we would have died of internal bleeding after sleeping in the cave for one night. But it doesn’t mean that we are all immune to harm.”
Song Siyuan paused: "We don't know how big this valley is yet. If we walk for too long, we will become inexplicably flustered and dizzy, or even vomit and have weak legs. This is because the body senses infrasound waves, which stimulates the animal's instinct to escape. .”
"We are human beings and know that these sound waves are just sound waves and can be overcome. These horses are animals. For them, infrasound waves are a warning before disaster strikes. They cannot walk into the valley in this situation."
