Fog is a very common natural weather phenomenon most of the time.

When the relative humidity reaches 100%, the water vapor in the air will condense into fine water droplets suspended in the air, reducing visibility at ground level, a weather phenomenon called fog.

The conditions for formation: one is cooling, the other is humidification, increasing the water vapor content. The types include radiation fog, advection fog, mixed fog, evaporation fog, etc.

When all the conditions are met, a large amount of fog can be artificially created.

Drifting out from the four openings and drifting in from the other four, it is not difficult to take advantage of the unique conditions of the mountains and forests to achieve the incredible things in front of you.

Therefore, compared to the fog, everyone's attention, including Wang Zhe, was on the huge corpse and the many blue human bones, what caused so many blue human bones?

After a neat gasp and unbelievable horror, it was as if the silence of time had finally been broken.

"What kind of animal is such a large corpse? Could it be a prehistoric creature, right? Why are there so many blue human bones here?"

"Who knows. I don't dare to compare it to this, I'm curious, why hasn't anyone found out about such a big and strange place before? ”

"Shennongjia is so big, there are a lot of things that have not been discovered, and there is nothing that should not be discovered. ”

"I think it should be related to the sudden earthquake in Shennongjia not long ago. There are a lot of traces of thought here, even if the years are very old, but these blue human bones, as well as those huge human bones, will they be related to the legend of the Shennongjia savages?"

"Maybe it's like American science fiction, there were aliens here who visited, but for some reason they all died here, and these bones are very likely aliens. ”

The sound of surprise and argument suddenly stopped, except for the silver dress, everyone looked at the speaker neatly, as a modern person, a young man with infinite fantasies and conjectures about the mysterious universe, they all felt that this seemingly wild speculation might be the strange truth here.

As for why so many aliens died here, it may be that they were infected with the earth virus and died, or that after the spaceship fell, all the aliens died here after their serious injuries did not heal.

Is there a more plausible explanation?

"There are words here, it seems to be an oracle bone inscription, do any of you understand?" After getting closer, someone found some words on the petrified white bones of the corpse, which were carved by someone, and after exclaiming, everyone except Wang Zhe shook their heads.

Yinshang didn't speak from beginning to end, she was concentrating on searching, looking for the unknown existence hidden here that made her faintly uneasy, and suddenly a strong wind blew, blowing all the fog in the cave sinkhole to all the cave tunnels behind Wang Zhe and the others, causing the fog outside to suddenly spread strangely and suddenly.

The wind blew through the broken bones like the wind carried the fallen leaves into the woods outside the cavern tunnels.

This scene surprised Leng Qingxue, Wu Shan and others, and they looked at it intently, faintly understanding why there were blue hand bones outside, and Wang Zhe said: "I took that blue hand bone, it is very light, just like foam, but it is normal to be willful and blown away by the wind." ”

His eyes then fell on the words on the petrified bones of the corpse, and he whispered: "Taste a hundred herbs to refine its medicine, the fire of civilization will be extinguished after all, and the body will be destroyed, and the chaos will be punished here......"

The content behind is not that Wang Zhe deliberately concealed it, but that the words on the corpse are gone, more precisely, those words have been worn out and damaged after thousands of years, as for whether there are words on the other half of the bones buried in the ground, Wang Zhe's perception is simply not perceptible.

After noticing the solemnity on Yinshang's face, Wang Zhe didn't bother, he was waiting, waiting for Yinshang to take the initiative to speak.

Wang Zheshan and the people on the side are naturally the same, and they carefully read Wang Zhe's whispered words in their minds.

Taste the herbs to refine its medicine, but any young man who knows a little bit of history knows that only Shennong tastes the herbs, not to mention that this is Shennongjia, which is enough to prove that the person who carved the words must be Shennong, one of the three emperors.

The flame of civilization was finally extinguished, and even Wang Zhe couldn't understand this sentence, not to mention the nine people who played soy sauce all the way, and paid more attention to the last fourteen words, the body and soul will be destroyed, and the chaos will be punished...... It should be understood that there is a prevention of disaster, and Shennong killed the owners of these bones here when they were alive.

", so we guessed wrong? These people are not aliens, but Shennong killed them, and they may cause trouble? Could this be a mass grave where many people died?"

"I guess there are hundreds of blue bones we see alone, but who knows what happened thousands of years ago. ”

"But why are all these people's bones blue? Could it have something to do with Shennong's tasting of herbs and refining medicine?"

……

The voices were out of control, until Yinsheng opened his mouth and whispered, "Found it!"

Silver Dress, who had been standing in place, walked around, and under everyone's gaze, she walked to the steep cliff, raised her hand, and a yellow light appeared, under which the originally steep cliff suddenly collapsed, revealing the ninth dark downward slope cave passage.

The uneven passage of the cave is enough to prove that it was naturally formed, and it was excavated artificially, but the entrance was sealed off, and the silver dress took the lead and walked in, and the spiritual perception could move forward in darkness without the need for light.

As for Wang Zhe and the others behind him, the flashlight function of a mobile phone is enough to support two or three hours, or even four hours, ten people have ten mobile phones, two at a time, and the light is enough for ten people to see the cave without fog clearly.

When the last man walked into the cave passage, Silverdress used the power of his Witch King to block the entrance with rocky soil again, not to prevent the white mist from coming back in, but to fear that he would upset some kind of balance.

This cave passage she can be sure that it must be Shennong Wuzu can be blocked, it seems very simple just now, but ordinary people can't come here at all There is a hidden cave passage here, you know, even she, the witch king, has sensed it for three minutes before finding it.

Thousands of years have passed, and she still needs to use sixty percent of her strength to break through the cave passage, which is enough to prove that there is an amazing secret hidden inside, maybe it is related to the extinguishing of the fire of civilization, no matter what, she must find it out for Wang Zhe before she exhausts the vitality in her body, and she must not let him take risks alone.

However, these words have never been advanced to Wang Zhe, maybe until the moment before she completely disappears into this world, some words will be spoken, say goodbye!

As we went deeper into the cavern passage, the uneasiness, which had not been strong at first, became apparent.

Although the oxygen content in the cave passage is a little low, it is enough for a group of people to survive here for a long time, but it is also related to their individuals.

The air was very humid, and as Yinshang withdrew the power of protection, even Wang Zhe found that his hair was wet and his clothes were also wet after walking for a few minutes.

"Tick tock, tick tock, tick ......"

The rising water vapor condensed into droplets on the cold stone walls, and the cave passages were narrow in some places, spacious in some places, and cautious in some places, sometimes high and sometimes low.

The further you go in, the more you will find that there are many forks, and sometimes you will find two or three holes when you turn a corner.

Even if there are many roads that connect with the outside world, but those who really enter and don't know the way will soon get lost, maybe turn around several times, and return to the original place.

Probably because there are many caves connected to the outside world, so that this dusty underground cave world has enough oxygen, and there will always be some faint wind, and there is a rhythmic sound like some kind of large animal breathing.

There seems to be a terrible ghost roaring in the ears.

Fearing unknown dangers, they were all nervously guarded, and once they knew that if it was some danger that they could solve, the fairy-like ancient humans might not come to their rescue.

Just like that sentence, if you die in a danger that you can clearly solve, if it is because of your own carelessness, then death is also a vain death.

Walking out of the cave passage, a huge karst cave appeared in front of everyone, huge and unimaginable, so that several girls couldn't help but ask in a low voice: "How did such a large underground cave form? It can't be dug out by hand, right?"

"yes, I've never seen a cave this big in my life. ”

The boy shook his head and didn't laugh, who has seen a few girls who are very good at geography and physics? And girls can be said to be a very magical creature, for example, many girls are road idiots, and they will get lost when they go out shopping, but when they go to a department store, they may not be lost when you go shopping.

Therefore, for such a simple question, he still smiled like a gentleman and replied softly: "It should be an underground dark river, such a large karst cave, it should have been an underground lake in the past." ”

The words fell, suddenly-

"Whoa, whoa, whoa—"

Suddenly, a piercing baby cry sounded in the darkness ahead, very loud, very weird, not the sound of the wind and a real baby crying.

"Wow Wow Wow ......"

Everyone shuddered, and there was a slight difference in the cry of the baby. One, two, three......

Especially when I thought of the fact that many people had died a long time ago, a chill suddenly surged from the soles of my feet to my whole body, and the five girls grabbed each other's clothes tightly at once, and covered their mouths with the other hand, forcing themselves not to scream.

so as not to be discovered by the unknown horror of the baby crying.

As for the boys, the four of them subconsciously got close to the girls, and the palms of their clenched hands were all scared out of cold sweat.
