This night, what made Yue Guanchao most curious was that there were really no wild beasts in the cave, even if the beasts roared outside the cave in the middle of the night, they couldn't step into the cave, he couldn't figure out what was in the cave that could make the beasts so afraid, if there were really terrifying things, why didn't they appear all night.

Could it be that it is not the physical object that scares the beast at all, but something that has no physical object in the first place?

Song Siyuan took out the Zhitu disk and handed it to Yue Guanchao, on the brass plate, the pointer began to rotate at will, trembling aimlessly, exactly the same as when they first entered Shennong Peak.

Yue Guanchao guessed: "Do you think that these stones are very likely to be of the same material as the stone table?" ”

Song Siyuan nodded with understanding: "Well, since the stone table can vibrate so much near the stone cave, it must be affected by it, although it does not indicate the direction, at least it proves that these stones can affect the operation of the brass plate, probably, the stone table does come from these caves, but it was only by the old craftsman that it has the effect of pointing out the direction." ”

She paused, and her eyes lit up: "The Sheji Temple on Shennong Peak, it seems that no animal dares to go over, if you speculate according to the principle, will some of the buildings of the Sheji Temple also use the stones here, so that the animals can be so afraid?" ”

Yue Guanchao also observed the beasts of Shennong Peak, they were indeed only entrenched around the Sheji Temple, but they did not dare to take a step forward, they used to think that it was the Sheji Temple that used what medicine to get rid of the beasts, and now it is mostly related to the stones that built the temple, and even, it is also related to the huge sculpture in the backyard.

In the stone cave in front of you, there are countless huge stone statues, if the stone statues in the backyard and the stone statues in front of you are the same material, then, the beasts dare not enter the cave, not because of some terrifying beasts in the cave, but because they are afraid of these mysterious stones.

Thinking of this, Yue Guanchao narrowed his eyes, his face full of doubts: "It's strange, could it be that wild beasts are afraid of stones?" Still, there are some things in the stone that I am afraid of, but the second uncle has also opened the stone pillar, and there is nothing in it. ”

"Perhaps, we didn't find the right direction, just go to Zhulin to have a look."

The inside story of the stone pillar is still hidden in the fog, and the two of them called Xu Xiake, Ban Wan, Ban Shu, and Yue Ercang, and a few people decided to take advantage of the craftsman to pack their bags and go into the canyon to talk about the situation first.

After descending the high slope and entering the canyon, the whole picture of the column forest also appeared in front of everyone.

When they stood on the high slope, their perspective was looking down, and they didn't feel how high the stone pillar was, but now they were standing on the ground, and then they realized the grandeur of the stone pillar forest.

Narrow and steep, standing on lonely peaks, these stone pillars are 100 meters high, there is no specific law on the length and width, as if they are stalactites standing between the canyons, the spacing is different, hundreds of pillars are arranged in turn, the surface is covered with moss, weeds, vines, shrubs cover the appearance, as if the whole body is covered with green gauze tents, and it is extraordinarily lush and lush.

Some of the stone pillars are too wide, and the steep slope of the top and body has grown a tall canopy from the rock crevices, and countless and dense groves of trees have appeared in various places of the pillars tens of hundreds of meters high, as if they were suspended in a canyon, with high and low staggered and endless

In the early morning, there is a lot of fog in the valley, on the pillars, the suspended forest hides into the mist, only to feel that the forest is in the clouds, graceful and ethereal.

They approached the stone pillar, looked up, only to see the pillar stone layer upon layer, like a three-dimensional suspended forest, the morning sun is shining, the red light covers the strange flowers and plants in the forest, and people have a feeling of being in a foreign land.

"This kind of forest, we've never seen it outside, isn't this a hole made by the gods of the ancestors?" Everyone was already stunned, Xu Xiake teased.

Song Siyuan picked up the soil shovel and stabbed it into the stone pillar, about half a meter later, the stone had already been topped, she explained: "This kind of forest is indeed strange, but it is not a cave made by some gods, the stone pillar we see now is probably taken from the cave." ”

"After thousands of years, these pillars continued to accumulate soil, weathering and erosion, so that the pillars were completely wrapped in soil, and vegetation began to appear on the pillars, and these steep terraces were produced after weathering and erosion, and then the seeds of plants and trees took root and sprouted on these terraces, forming this forest suspended on the pillars."

"Let's dig up the dirt and see what the pillars have become!"

They picked up the sapper shovel, found a thin stone pillar, eradicated the vegetation covering the surface, and dug up the ground at the same time, and when they dug a one-meter square gap, they could already see the surface of the pillar stone.

Turn on the flashlight and approach the pillars, although thousands of years have passed, these pillars have only been slightly eroded, the main body is still intact, and you can see that the structure between the stone bars is similar to the arrangement of bamboo strips, nested with each other to form a huge body.

The surface has the same metal veins as the grotto stone strips, and some of the metal veins have protruded from the surface of the stone due to the erosion of the stone.

Song Siyuan just took advantage of this opportunity to shovel off the metal that had protruded from the stone.

After a busy meal, some metal veins, and even the surrounding stones were knocked down, and when they took out the hole in the ground, Yue Guanchao observed these things.

The shape of the metal vein is irregular, as if pulling the metal at will, forming flakes and filamentous lines, each with its own weirdness, the ore near it is a lot more normal, most of them are burnt yellow, gray and white, brown gray, under the illumination of the flashlight, it can be seen that part of the light can penetrate, not completely impermeable to the light.

Song Siyuan picked up the metal vein and tapped it with a shovel for a moment, and could feel the metal trembling.

"It's copper!"

The metal in front of you is yellow and clear, not as dazzling as purified gold, and you can only see a slight glittering luster, probably similar to unpurified gold ore, but when you hold it in your hand, you don't have the heavy pressure of gold, so it is basically determined to be brass.

"There's nothing special about this thing, we've seen a lot of brass, it can't be a beast afraid of brass." Yue Guanchao guessed.

Song Siyuan picked up these brass veins, picked up the stones on the side, and his eyes lit up: "These stones are quartzite, mainly composed of quartz, which is a kind of rock formed by quartz sandstone or other siliceous rocks through regional metamorphism, in addition, siliceous rocks near magma can also be metamorphized by thermal contact to form new quartzite." ”

"What the hell do you mean?" Yue Erpao scratched his head.

Song Siyuan explained: "The presence of such rock formations here is precisely to understand that the mountains in this area have had volcanoes, or, tens of millions of years ago, the mountains here were covered with magma, and after the orogeny, the stones were subjected to high temperatures, forming the large quartzite peaks we see." ”

"After that, the ghost people discovered these quartzite peaks, mined stones on the canyon mountains on both sides, and used them to make stone pillars, leaving countless caves, these stone statues were probably used by them to act as protectors, just like the statues of mountain gods in the outside world, playing a protective role."

"So, what does this have to do with animals being afraid of the valley?" Xu Xiake's eyes were full of doubts.

Song Siyuan picked up the stones: "Quartzite is silica, which has excellent conductivity and can record sound, and the heart used to store sound in the tape recorder is silica." ”

"Recording sound?"

When the crowd heard this, their eyes lit up.

Yue Guanchao narrowed his eyes: "How can the stone be recorded, there is no electricity, oil and water or anything, can you really record the sound?" ”

Song Siyuan nodded: "I've read some scientific magazines that quartzite has high conductivity, enough to store sound in it, and then when the opportunity is right, the recorded sound will be released, and this property is often used to make tape recorders or phonographs." ”

"Just." She changed her words: "The quartzite that appears in nature often does not have the convenient characteristics of industrial tape recorders, and has many shortcomings in recording and playback, such as the inability to delete the recorded sound, the recording quality is not clear, and the playback process is also easy to be interrupted by interference, or there are a lot of noises." ”

Song Siyuan continued: "I think that the noisy ghost whispers in the ghost whispering forest are probably the sound of mountain wind and rain, deciduous grass, and animal howls recorded by quartzite. ”

Everyone obviously didn't believe her words, Song Siyuan knew that it was difficult to make them believe, and continued to explain: "The ghost of the human-faced bug we saw also appeared in the picture of the ancient march, this Ming human-faced bug has eaten the flesh and blood of the ancient marching soldiers in history, and at the same time, it also has their memory, which can form a terrifying picture of the crossing of the Yin soldiers. ”

Her face became mysterious when she mentioned this: "This proves that there were a large number of ancient soldiers in Shennongjia at a certain historical stage, and if you think about the special geographical location here and the biography of Emperor Wu of the Song Dynasty, it is clear that they are probably the soldiers of the Northern Mansion of the Song State during the Northern and Southern Dynasties." ”

They gathered in Shennongjia in large numbers, the purpose may be to build the Beifu Clothes Tomb, in the process, many of them were eaten by the face bugs, and when they passed through the Ghost Whisper Forest, they also left a lot of marching sounds, in the eyes of Orion, this is the Yin soldiers talking and doing things.

This kind of thing is special but not inexplicable, Song Siyuan decided to give them another example to understand the principle: "Not only the stone can be recorded, but even the palace wall can be recorded in some cases, this is not in the deep mountains and forests but in the capital, and it is related to the death of Concubine Zhen." ”

It is rumored that Concubine Zhen and her sister grew up in Guangzhou, lively and open, love new things, because of their support for the Restoration, they have not been treated by Lafayette for a long time, and because they have repeatedly contradicted Lafayette and were imprisoned by the Queen Mother, after the Eight-Nation Coalition Army entered Beijing, the Queen Mother disliked her as a burden, gave her the punishment of sinking into the well, and lost her life.

Soon after the old queen mother returned to Luan, the ladies in the palace could always see a ghost of Concubine Zhen being dragged away in a palace wall, and the number of people who saw it was countless.
