"Frozen corpses in the cave?"

Before Song Siyuan's words fell, Yue Guanchao also turned on the flashlight and shone it over, originally he thought he was dazzled, but after the light intensified, even the details of the corpse began to become clear.

The corpses, more than one, were almost all on the tidal flats, they were either running or standing, or they were pushed to the ground, crawling forward, in a way that squeezed each other's heads and feet, they were frozen on the tidal flats, and their whole bodies were condensed by the fog, and thick hoarfrost appeared, and if you looked at them from a distance, if you didn't distinguish them carefully, they looked like a pile of gray and white sculptures.

Under the watchlight of the kerosene lamp, a group of ice sculptures appeared in the cave, and everyone could feel a cold air rising from the soles of their feet to the top of their heads, and their brains hurt.

At any time, as long as a large number of corpses appear nearby, at least it means that the environment is unsafe, and everyone is worried.

"Stop, this corpse is so weird, we can't go any further, let's see what is going on."

After Song Siyuan finished speaking, the carriage had stopped one after another near the river beach, Yue Guanchao, Song Siyuan, and Xu Xiake got off the carriage, and the ghost Fangzong also got off the carriage, and several people got off the road together, and walked downhill for dozens of meters to the beach.

Walking on the tidal flats, the feet were full of frozen stones and mud, there were more corpses than they thought, and more details of the corpses began to become richer.

Yue Guanchao picked up the sapper shovel in his hand and slapped it on the corpse a few times, and after the cold white frost fell, the true appearance of the corpse was also revealed from the ice and snow white frost.

"Why are they all ancients."

Yue Guanchao took a few more ice sculptures and found that the clothes were all the clothes of the ancients, and there were no modern people's clothes.

If you look closely, these people are probably some ancient soldiers, with burly figures, resolute faces, different appearances from north to south, most of them are wearing soft jackets and swords, their eyes are full of horror, and even their necks have different degrees of stabbing wounds, as if they were pierced by something in the cervical vertebrae, and they died of terror after being bled out.

All people, although they die in different ways, are all fatal for the same reason.

Song Siyuan turned on the flashlight, carefully observed these corpses, and explained to everyone: "Judging from the dress of the corpses, these are not the corpses produced recently, some of the corpses have been swollen and soaked, as if they looked like they were repeatedly thawed and frozen, and they were probably ancient soldiers." ”

"Beifu soldiers?"

Xu Xiake's eyes lit up, Shennongjia was weird and bizarre, and the only ones who had really been here were Beifu soldiers.

His guess was obviously playful, and Song Siyuan nodded: "It is very likely that these soldiers are wearing two crotch armor from the Northern and Southern Dynasties, this kind of two-crotch armor is different from close-fitting armor, it is level with the shoulders, up to the knee, and is woven into a rectangle with thumb-thick clips, with two pieces in the front and back to form a circle, and there are ties on both shoulders and waist. ”

"Let's look at these clothes again, there is no difference between them and the two crotch armors, and they are the most likely to be soldiers from the north and the south to the north."

"It's just, why are their bodies here?"

Seeing now, Song Siyuan is no longer curious about the identity of these corpses, but the reason why the corpses exist in the cave.

"Could it be, it was forgotten in the cave by the Beifu soldiers!" Yue Guanchao guessed.

Song Siyuan looked at their direction and walked outside the cave, as if she had guessed something, and explained: "Impossible, these people are not dead people, they can still go out if they are forgotten in the cave, from the direction they walked, it was probably in the direction of Shenji Ling, but they probably didn't go out yet, they were attacked by something, and the penetrating wound in the neck directly pierced the cervical vertebrae, causing them to die on the spot."

She paused and continued to explain: "Due to the low temperature in the cave, their corpses were frozen before they had time to decompose, and it is likely that they have been thawed and thawed for thousands of years, making the skin show signs of foaming, a little bit giant-looking. ”

"There's a different corpse here."

As they spoke, the Ghost Fang Sect stood nearby and reminded that Yue Guanchao and they came closer to see that it was really completely different from the soldiers of the Northern Mansion.

Just now, all the corpses were covered with snow-white frost, and the physical characteristics were not outstanding, and the hoarfrost on the body was knocked off, and one of the corpses was obviously white and glowing, and it looked like it was white jade, and the skin color of Banshu was too similar, and it was basically determined that it was a ghost person.

"The ghost people also died here? Look how she died. ”

When they heard this, their eyes became puzzled.

Song Siyuan carefully rummaged through the neck of the corpse, and there was no puncture wound from these Beifu soldiers, her eyes lit up: "Could it be that the ghost people chased and killed these Beifu soldiers, and the wounds on their bodies are actually some kind of weapon of the ghost people?" ”

Ghost Fang Sect said: "These Beifu soldiers are all a way to die, but this ghost Fang person has no wounds and still appears here, that is probably the murderer who killed the Beifu soldiers." ”

Although Song Siyuan knew part of the truth, she was indeed puzzled by this: "Since the ghost people want to kill the Beifu soldiers, does it mean that these Beifu soldiers have done something to the ghost people, or are the ghost people chasing and killing them for other purposes?" ”

"Then, who killed this ghost man?"

This string of questions came out of Song Siyuan's mouth, and it also made others confused.

Yue Guanchao shisped his teeth and shook his head left and right: "Since we entered Shennongjia, we have found giant statues and giant heads, and we have found that the ghost people have lost control of the ghost artifact. ”

"Possibly."

Song Siyuan nodded: "Indeed, this proves that our guess has indeed come true, something must have happened in that ghost world, and these Beifu soldiers will escape." ”

"Now, we can't see anything, I want to know, why is there such a group of ice sculptures in this cave, is it that it has been so cold in the cave for thousands of years?"

After that, Song Siyuan walked along the tidal flat to the river, squatted on the ground and put her hand into the underground river, the river water is not hot, the touch is close to the temperature of the human body, the temperature is just right, and the mist floating on the water surface has a very strong sulfur smell.

"This is a geothermal river!" She returned to Yue Guanchao and explained: "The geothermal river is the same as the hot springs, it is the geothermal water generated by the underground heat source near the underground water source, which is estimated to be the geothermal heat generated by the Danxia Basin, and the water flows directly into the valley through the river. ”

"Because of the presence of geothermal rivers, the fog in the cave will never disperse, and I guess it is the fog that condenses on the corpses to form a thick hoarfrost."

Xu Xiake asked: "But the key is, where does this cold air come from, this tunnel has nine twists and turns, and what blows in can only be cold wind, and it can't be cold air." ”

"It's freezing up there, it's getting hot below, and I suspect it's the upper part of the rock formation."

After that, Song Siyuan turned on the flashlight and looked up, but the light was blocked by the fog and was completely impenetrable.

She then returned to the carriage and stepped on the pedal to the top of the carriage, high enough to touch the fog.

After Song Siyuan stood on the top of the carriage, half of her body had already penetrated into the fog, only to see the lights appear on the upper layer of the fog, hazy, and endless.

"Yue Guanchao, come up and see, I found the reason."

Seeing the situation, Yue Guanchao also stood in the carriage and got into the fog, and when the haze in front of him dissipated, he gradually saw the scene on the upper layer of the fog.

In the light of the flashlight, the upper layer of the cave is covered with almost transparent ice, as if a layer of translucent ointment has been pasted along the upper part of the tunnel, and the pillars of the rock formations with canine teeth are clearly visible, and even some plants can be seen frozen in it, and it is impossible to get rid of it.

The closer they got to the upper layer, the greater the chill, and a white mist had appeared between their breaths, and the air they inhaled into their noses was like carrying ice slag, all the way from the nose to the lung tubes, and even, the runny nose was frozen into ice skates, and their bodies began to be covered with a layer of frost.

The two of them endured the severe cold, scattered left and right to observe, these fog appeared from the river, continue to spread towards the caves on both sides of the river, because the water mist is relatively heavy, they can only be suspended in the air, as the fog continues to be generated, these half-empty fog will be lifted to the ice, in the condensation into hoarfrost, directly to the ground, and then, the fog from the river continues to generate, which also makes the cave perennial fog not disperse.

Yue Guanchao picked up the sapper shovel and threw it towards the ice skate closest to them, and with a click, the ice skate broke and fell to the ground.

They got out of the carriage and picked up these ice skates, the tentacles were extremely cold, and there was no sign of melting in their hands, and they picked up the flashlight and shone it on it, and they could see the translucent texture, which was not only like ice skates, but also a little close to crystal.

Yue Guanchao picked up the kerosene lamp and put the half of the ice skate in the center of the flame, and after being heated, some water beads appeared around it, but there was no sign of melting: "It's strange, it's as cold as an ice skate, it can't be burned, what the hell is this." The crowd became curious about what was in front of them.

Song Siyuan looked at this thing, and explained curiously: "According to this transparency, it is probably the crystallization of some kind of ore, which is so cold to the touch, and there is also an ice component in it, I suspect that it is some ore crystals and impurities formed by ice." ”

"Impurity ice?"

Yue Guanchao motioned for her to continue explaining.

Song Siyuan pointed to this thing and explained: "Impurity ice is between ore and ice, both the cold of ice and the stability of ore, it is not easy to melt, although this kind of thing is scarce, it is still possible." ”

For example, on some icebergs on the plateau, there have been thousands of years of frozen soil, because the icebergs on the plateau have a cold climate all year round, so that the ice and snow here have never melted, and dust impurities have accumulated on the ice for many years, which will freeze the ice and impurities together, forming iceless ice and frozen soil.

The permafrost appears to be very hard, but when the temperature is high enough, when the permafrost thaws, it will turn into moist soft mud and release water from the frozen soil.
