Song Siyuan seemed to have thought of this, and continued to explain: "The corpse will decay, entirely because the humid environment is suitable for the survival of bacteria and microorganisms in the body, and when the microorganisms in the body begin to multiply, the corpse will continue to decay, and then a large amount of gas will be produced in the body. ”

She paused and continued: "If the corpse is kept in a very dry environment with little water, it will directly bypass the decay process of the giant view, forming some dry corpses with complete bodies and lifelike organs, and those mummies in the Egyptian desert are completely dry corpses, and the state they present, except that they have been severely shrunk, is no different from their appearance before death, and scientists can even restore their appearance by restoring the shrunken parts." ”

Speaking of this, she looked at the monk's corpse: "The northwest environment itself is dry and rainless, and here is close to the desert, which adds a bit of dryness, and when the monk's corpse dies in the shrine, it is estimated that there is not much water in the underground drain, which can dehydrate the corpse for thousands of years and form such a complete appearance." ”

"But."

She changed her words: "Because the corpse has lacked water after all, in the case of frequent disturbance, these already dry skin will gradually lose its elasticity due to the loss of moisture under the pull, and in the process of ringing the bell for thousands of years, the outer skin of the arm is constantly broken, and the dry flesh and blood are directly exposed to the cold wind, which accelerates the degree of decay and fall." ”

After that, Song Siyuan picked up the discarded wooden board from the outside, and directly covered the iron plate behind the monk's corpse, just with this one action, he had already seen the cold wind behind the monk's corpse disappear, and when the cold wind blowing forward of the monk's corpse disappeared, the corpse's strength to lie forward disappeared, and it was completely blown on its back by the cold wind on the opposite side, and there was no longer any activity just now.

This shows that as long as the cold wind dissipates before and after, the force that prompts the activity of the monk corpse will be completely unbalanced, and the monk corpse will certainly not be able to ring the bell with a single force, which has proved to everyone that her guess is right.

"The secret of the corpse's activity has been solved, but what about the chanting ghost sound above the tower?"

Yue Guanchao looked at the bronze bell under the floating slaughter.

Song Siyuan seemed to be still suspicious of this, picked up the flashlight to carefully observe the bronze bell, and used the sapper pickaxe in his hand to strike the bronze bell.

In the disturbance of the sapper pickaxe, the sound in the bronze bell is still a noisy ghost, which shows that the sound of the bronze bell is not controlled by the monk's corpse, but is related to this bronze bell.

Song Siyuan struck the bronze bell with a sapper pickaxe: "The problem is here, the bronze bell seems to have some recording functions. ”

She paused and looked at everyone: "Do you still remember, the ghost language forest we met in Shennongjia!" ”

At that time, after they entered Shennongjia, they met the pillar forest that would emit ghost whispers at night, and they originally thought that this was the ghost god at night, until they entered some quarrying caves, and found that the material of those pillar forests was the same as the material of the stones in the cave.

After some observation and demonstration, they found that it was the metal veins mixed in the pillar stone that played a role, and they had the function of some simple tape recorder in the resonance of underground activities, so that all the sounds in the vicinity were recorded, and when the stone was shaken by the geothermal heat at night, it was constantly played on a loop, and new sounds were also recorded.

After this incident, they solved the secret of the ghost sound disturbance in the Ghost Whisper Pillar Forest!

Of course, Yue Guanchao knew this, but he obviously didn't believe in such a coincidence, squinted his eyes and teased: "Song Qianjin, you can't hear any ghost sounds, it's all said to be a simple tape recorder!" ”

"I'm not kidding, I don't believe you look inside these bells!"

After that, she motioned everyone to look inside the bronze bell, and after the flashlight shone, everyone stood under the bronze bell and looked at the inner wall of the bronze bell, and sure enough, they still found the clue.

"Is this red mineral powder?"

Song Siyuan carefully observed the inner wall of the bronze bell, the inner wall was not brass, and there was no patina produced by years of corrosion, but showed a slightly dull vermilion, which looked like a layer of red paint.

These pigments do not feel the smooth texture of paint, similar to the rough texture of sand and gravel, if you look closely, you can also feel the rough particles on the surface of the paint, as if you are touching some sandpaper, rubbing the inner layer of the copper bell with your hands, there can also be large red particles, and it smells of rust, which shows that there is no problem with her opinion.

She explains her opinion: "I feel that these pigments must contain a lot of iron powder, which has been oxidized to give it the dull vermilion color it is now. ”

"The redness of these paints is a chemical phenomenon of iron powder oxidation, and the oxidized iron is called iron oxide, which can be used to make tape recorders, video recorders, tapes, and telecommunications equipment."

Yue Guanchao had heard her mention the ghost shadow on the palace wall of the Forbidden City before, because the red wall of the Forbidden City contained a large amount of iron powder, and they formed a more red iron oxide after oxidation.

Under the premise of unknown circumstances, the palace people in the Forbidden City understood these images that were played as ghosts, and until the secret of the palace wall was cracked, the old queen mother of the former dynasty was not at ease.

At this time, he heard Song Siyuan mention iron oxide, which was undoubtedly equivalent to seeing the real thing, and asked: "Does that mean that the iron oxide formed by this layer of pigment after oxidation is recorded in the sounds existing in the ancient city under special conditions, and these sounds are preserved?"

Song Siyuan nodded at him and continued: "The principle is like this, but one thing we do have to know is that these iron oxide pigments can be recorded, but in the absence of playback power, it is impossible to actively play and record the sound. ”

Then, she looked at the monk's corpse: "This corpse was disturbed by the wind, directly let the corpse start to beat the bronze bell, at this time, the bronze bell is equivalent to having some kinetic energy, in the indefinite vibration of the bronze bell, those sounds recorded by the iron powder, were released by the tower body, and were heard by those of us who happened to pass by, thinking that it was the soul of the ancient city that was doing it." ”

Xu Xiake was puzzled and asked: "However, why did this monk tie himself to the prayer pestle, and even fixed his waist with a rope, could it be that he knew in advance that the cold wind would blow him, and deliberately shaped himself into this state?" ”

"Perhaps, the structure of these bronze bells is the masterpiece of these Tibetan monks!"
