On a cold desert night, the temperature was so low that everyone shivered their teeth and shivered from the cold.

Now that you have found the direction, you can either take advantage of the victory to pursue it, or go home first, and then spend it here like this, and everyone who has just walked out of the "hotel hospital" will fall ill again.

Everyone looked at Bai Yunfei, and Bai Yunfei said: "My personal idea is to act now, and coming back tomorrow will be the same as today, it can only be done at night, how can it be possible during the day?" After all, this place has become an attraction, and it is hard to guarantee that it will not be discovered. ”

After speaking, he looked at Cao Longxuan, meaning to see what else he thought. Cao Longxuan whispered a few words to Sun Er, and then pointed to the position where Li Yulan's flashlight beam was pointing just now, and everyone ran there quickly.

There is a saying that "looking at the mountain and running a dead horse", after all, there will be a big difference between what people see and what they actually do, and everyone ran in the howling cold wind for a while before running into the rift.

Turning left and right in the ravine that fell into the cliff, he had completely walked into darkness, and there was not a single moonlight in sight, and he was completely shrouded in darkness by the towering mountain beams around him.

The boundless darkness gives people a great depression, although there are a few flashlights shaking, but it can't help but make people frightened, those words about "devil", "soul", "pagoda" and so on, have been preconceived imprinted in the heart, although repeated silent recitation do not believe in feudal superstition, but still can't help but feel hairy in the heart.

This tortuous rift valley has finally come to an end, and several small ravines nearby have also converged here, and in front of it is the steep cliff on this side of the mountain beam, and when you look at the top of the cliff directly into the starry sky, it is actually unattainable.

But when you look at the parking highway, these mountain beams are just like some undulating mounds, which feel inconspicuous, showing the insignificance of human beings, and once you are in them, you can truly appreciate the grandeur of nature.

Looking around, I found that the geological structure here is no different from other places, it is completely the soil structure of the Yadan landform, and there is no imaginary "cave", "entrance" or anything like that.

But even if the entrance is here, the current situation is the most normal, otherwise it would have been discovered by others a long time ago.

Moreover, this kind of Yadan geology is very soft, thousands of years of wind and rain erosion, landslides, collapses and other situations are naturally prone to occur, no matter whether there is or not, the possibility of being buried is 100%.

Cao Longxuan asked everyone to quickly take out all the clothes stored in the backpack and put them on to keep out the cold, and asked Sun Er to arrange for people to find dead poplar trees and other vegetation nearby, and cut them back to make a fire for everyone to heat and light.

Then he and Su Lao Ghost studied where to start, Su Lao Ghost walked around, jumping and jumping from time to time, and knocked this and that with the Luoyang shovel in his hand.

Gritting his teeth, he took a shovel and drew a circle on the ground with a diameter of about two meters, which means "here it is." ”

So Sun Er and another subordinate, under the illumination of several flashlights of the people, began to dig down from this circle.

Although everyone increased their clothes, they were still too cold to shiver, but fortunately, the two guys who went to find dead wood each came back with a large hug of dead branches, and after the fire was lit, the power of the flashlight was saved, and everyone gathered around the fire immediately warmed up a lot.

In order to prevent accidents, Cao Longxuan arranged for a person to be on duty in the car on the side of the highway to prevent accidents from occurring after the fire in the rift was discovered.

After the people in the car saw the abnormal situation, they quickly reported it with the walkie-talkie, so that everyone in the ditch could respond in advance.

In order to speed up in a hurry, everyone took turns to join the ranks of excavation after they were warm, and these early strength work should be the work of Sun Er and his three subordinates, so that everyone can maintain sufficient physical strength and energy.

However, considering the time limit of safety, considering the abnormal temperature in the desert, we must hurry up to find the entrance, there are too many unknown risks faced by this kind of dungeon exploration, and time is often the key to success or failure.

All eleven of the men, except for the man who had been on guard in the car, joined the excavation, but it was difficult to say how anything could be so precise based on judgment, and whether there really was a so-called tomb or entrance here.

So without digging anything out, the circle with a diameter of about three meters had to be abandoned.

Old Ghost Su chose another place for everyone to dig, and everyone fought for several hours, and after digging a few meters deep, they dug a few more soil holes horizontally.

A few branches have grown horizontally on the trunk of a tree, which have been dug out horizontally for more than ten meters, and after still finding nothing, everyone began to rest tiredly.

During the break, everyone began to discuss whether it was necessary to dig further, and now everyone is not so convinced.

Although the "shadow of the devil" was discussed at the beginning, there were many sparks of inspiration, but after all, it was an imagination, and the process of using something imaginary as an argument was obviously unreliable.

So everyone decided to dig one last time, and if they couldn't find anything again, they would give up first and then study a new way.

This time, Su Lao Ghost compared the first two holes, measured for a long time, and drew a circle in a position, everyone threw off their arms and began to dig holes, Su Lao Ghost asked everyone to dig down at least ten meters deep, and then dig out at least thirty meters laterally.

During this period, the dead branches were burned out twice, and a guy and the one who was on guard were replenished with new ones, and this time two more hugs.

Bai Yunfei looked at the broken branch of the tree, which was obviously sawed with the gasoline he brought, which was really labor-saving.

I pondered in my heart, if this modern person steals the tomb, it is much more convenient than the ancient people, because modern science and technology are developed, and many problems that are difficult for the ancients to solve are not a problem at all in the eyes of everyone.

When Bai Yunfei sat by the fire and thought about this, it was his turn to rest for a while, and the others were digging and digging, pulling up and pulling the soil, but there were too many people to intervene, so they could only take turns with each other.

Li Yulan temporarily ended her work and sat next to Bai Yunfei, she came to see the direction of the soil hole that Bai Yunfei scribbled on a piece of paper, and the two of them chatted about digging holes, and there was nothing worth discussing, so they began to roast the fire silently.

When Li Yulan was roasting, she looked up at the sky, and Bai Yunfei looked in the direction she was looking, thinking that she had found some valuable clues, but it turned out that she was in a trance.

Bai Yunfei also looked at her like this for a long time, and then heard her say softly: "The starry sky is so beautiful. ”

Bai Yunfei dealt casually: "Yes." ”

But I sighed in my heart, such a beautiful woman, who should be sitting at home watching the starry sky, not at home with her husband and children, and living a happy family life, but she came to do the work of exploring this underground palace, she can only say the word "love", and how many people can not be burdened by it?

Bai Yunfei suddenly felt ridiculous, not to make fun of this beautiful woman, but to all the people in front of him, including himself.

Maybe none of these people thought before that they would become underground explorers like "Tufuzi", and they were all caught up in it by mistake.

But even if you have a picture, a symbol, and an ambition, the picture, the symbol, and the ambition add up, but you are still a native master.

The person who digs the hole and steals the drill is like a huge groundhog, digging aimlessly in the ground, ridiculously looking for what he wants, but helplessly deviating from his own life.

After several rounds of rotation of manpower, the sky was already bright, and everyone couldn't help but feel anxious.

Lu Wuyang, who was digging a hole horizontally below, shouted below, saying that it was at least thirty meters, and everyone's hearts were a little heavy.

Cao Longxuan's face was expressionless, and after saying something to continue, everyone began to dig hard again.

Until digging nearly 50 meters, the people below said that they had dug up rocks, which was normal.

But what is exciting is that there is news that there is a layer of lime between the soil and the rocks, and its thickness is very uniform, not like natural, but as if it was artificially formed.

Due to the limited space, everyone took turns to watch it, and then they all came up to study and analyze.

Everyone agreed that this layer of lime was evenly distributed, and the signs of artificiality were very obvious, and Su Lao Ghost was a little overjoyed, saying that it could basically be concluded that the tomb or passage was used to seal or prevent moisture and insects.

As for whether there is a passage or not, it is very easy to do, digging along the surface of this rock, although the amount of work is large, but as long as there are tombs, it should not be difficult to find the passage mouth.

Everyone was determined to fight a tough battle, and went down to the cave again with the belief that Yugong would move mountains, but they didn't expect that Niu Gang had just dug for less than ten minutes before he crawled out and shouted:

"Stones, oh my mother, there are thieves pulling up the stones and putting them there!"

The people in the back couldn't squeeze in front of them, they couldn't see the situation, and wanted to expand the width of the hole, but they were stopped by Cao Longxuan, saying that it was easy to cause collapse.

The people in the back waited eagerly in the back, and could only see the backs of the people in front kneeling and crawling in front.

But no matter what, I actually found a neatly stacked stone, which must be artificial, no matter how miraculous nature is, it is impossible to cut the stone to play with, and then stack them into the ground and bury them.

Unless God likes to play mahjong in the ancient flood era? Cut out a stone for mahjong? There's no need to bury it in the ground.

Cao Longxuan asked the sentry to bring gas welding equipment from the car, which was the kind of "water welding" that combined oxygen cylinders and acetylene bottles, and directly used its high-temperature flames to cut the gaps between the stones that were filled with molten iron.

Until this time, everyone's hanging heart finally landed, if the guess is right, this part sealed by a large number of stones should be the entrance to the underground palace.

With the development of modern science and technology, this blocking method of pouring molten iron with stones, which was an unusual headache for tomb robbers in ancient times, was easily broken in the hands of everyone.

Everyone cleared away the many stones, and a black hole appeared in the flashlight.

Su Lao Ghost threw a match that he made to probe the oxygen content inside, and found that the oxygen was sufficient, he stood at the entrance of the cave and sniffed vigorously for a long time, and judged from experience that although the air inside was cold and damp.

However, there is no serious mildew and obscurity, and it is not the kind of space that is old but completely closed and lacks oxygen, so you don't need to wear a gas mask first, and then you can adapt when you enter it.

Cao Longxuan asked Sun Er to take the other three people to cover the hole with branches and other sundries, backfill and level the stolen soil, and do a good job of camouflage, while the rest of the people began to march.

This karst cave should be a branch of the main karst cave, the space is narrow, and there are basically no unique features such as stone stalactites and stalagmites, mainly on the stone wall that twists and turns, and is uneven, and is covered with dripping karst holes.

It seems that compared with those historical karst caves that have been formed tens of thousands of years ago, they should be underground karst caves that have been formed more recently.

Now it may be that the underground river has been diverted or the water source has dried up, and the hole has long been devoid of water droplets, only the dust that has accumulated over time.
