Just when a few people were enjoying the cold comfort, they heard Niu Gang's sharp scream: "Ahhhhhhhh ”

His scream frightened everyone into a tremble, his body was unstable, and he slipped into the water at once, choking on several mouthfuls of water.

I was swept away by the current, and I almost didn't go down the river to the turbulent area, but after a struggle, I finally grabbed the stone on the bank of the river and climbed back.

If you slow down a little longer, you may be swept into the turbulent water, and it is difficult to say whether you can swim back, after all, except for the exposed head and arms, the whole body and legs have been almost numb by ice, and even if the water is good, you may drown.

Everyone gasped a few times, and were about to scold Niu Gang for why he was scaring everyone, but when they saw that he was struggling violently and had already climbed towards the shore with all his might, they realized that he could not be messing around at all.

He usually doesn't smile, and it's even more impossible to joke with everyone casually.

And judging by the intensity of his struggle, he must have encountered something terrible.

When everyone was wondering and began to be shocked, suddenly Bai Yunfei's leg was in severe pain, as if he had been stabbed by a sharp knife, and then there was a sudden pain in several parts of his legs.

Bai Yunfei's first reaction was that something was biting him!

So by the originally calm dark river, for a while the ghosts cried and wolves howled, and everyone screamed in panic and crawled to the shore.

Fortunately, there were two people on the shore who were pulling the crowd, and they soaked in the water with the rocks on the bank of the river, but did not swim into the river, so they struggled a few times, and finally climbed onto the shore amid the screams.

At the moment when everyone came out of the water, the things that bit everyone were still attacking their legs.

With the flashlight of the people on the riverbank, Bai Yunfei clearly saw that they were several black and purple strange fish with two palms in size.

It may be that he has lived in the underground world without light for many years, and his eyes have turned gray, like no pupils, but there are traces of black and brown in the abrupt big white eyeballs.

The mouths of these fish are very wide, full of sharp teeth, and they make a "click" sound when they bite together, which makes people feel shocked.

Everyone was shocked, and used a flashlight to shine a flashlight on the watery pants on their legs, and found that the black security uniform pants were not only dripping with water, but also bleeding!

In the places where there was a great pain just now, the pants had been torn, the flesh had been bitten off, and the blood was pouring downward.

Everyone quickly took out the first-aid kit, quickly treated the wound, disinfected and bandaged.

After everything was dealt with, everyone stared nervously at the empty, dark river, which was still flowing rapidly, and there were no waves on the river.

Sun Er said that fortunately, someone on the shore pulled everyone up, otherwise it would be really troublesome.

Because everyone has been numbed by the cold dark river water, after being attacked, the more nervous and anxious they are, the more their legs and feet do not obey the call. I won't be able to pounce for a while, and it is estimated that by the time I climb up, the lower half of my body has been eaten into a bone frame.

"It's not a crocodile either, is it? It's so brutal. Bai Yunfei asked suspiciously.

"No, it won't." Thirteen said with certainty: "The crocodile has a large body, a large mouth, and great strength, if it were a crocodile, everyone would have been bitten and dragged to the river to die, and it is impossible to bite off a small piece of flesh." ”

"And what do you mean these calves are piranhas?" Niu Gang was very angry at being bitten, muttering that he would pick up the bitten things and cramp, peel them, and eat meat.

"Very likely." Cao Longxuan's eyes stared at the river, his expression a little solemn.

Bai Yunfei suddenly said: "Since there are piranhas in the river, let's not cross the river easily, although there are many species of piranhas in this world, whether they are in the sea or freshwater, piranhas are group creatures, since there is one, there will be many."

Now I look at the calm surface of the water, but there are only a few occasional ones, and they haven't caused a large crowd yet.

But to rush across the river is undoubtedly to send you to death.

Now that the incense poison on everyone's body has almost been resolved, it is better for everyone to go upstream and take a look. ”

Sun Er asked a little puzzled why he wanted to go upstream, this underground river stretches for thousands of miles, and if you go along the dark river, isn't it out of the scope of the ancient tomb?

Bai Yunfei explained that when he used a flashlight to irradiate the upstream and downstream just now, he saw a faint black thing in the upper reaches of the large drop river section.

Although I can't see what it is, it is certainly not a natural creation, it should be artificial, so what kind of people will build artificial things in these tens of millions of years of isolated underground rivers?

The answer is basically certain, it should be the owner of this ancient tomb or the designer of the tomb.

Everyone felt that Bai Yunfei's analysis was very correct, so they packed their bags, put on a new gas mask and a novice flashlight, and prepared to walk upstream of the drop river.

This underground trip has reached the current position, the power of the flashlight, and the filtration performance of the gas mask have been exhausted, and it must be replaced with a new one.

When everyone was replacing the filter parts of the novice flashlight and gas mask, considering that the next way out might be in the cave opposite the dark river in front of him, Cao Longxuan took out a flare gun and fired a signal flare at the cave opposite the dark river, and in an instant, the entire bank of the dark river was illuminated by the white signal flares.

I saw a strong flare dragging the tracer straight into the cave on the opposite side, although the dark river is wide and very far away, but this signal flare is too bright, and you can still faintly see the situation in the cave on the opposite side.

Although there are stalactites, stalagmites and other unique features in the cave on the opposite side, but the terrain is sharply downward, the bright tracer light in the opposite side after hitting the stalactite pillar, scattered and splashed, fluorescence is sheng, like a fire tree silver flower blooms tens of millions of fluorescence, simply expand into a round of underground dazzling sun.

Then the silver flowers splashed and fell one after another, falling into the depths of the cave. Eventually, it fades into a fade.

Just as everyone was about to leave the gap on both sides of the dark river, they found that the opposite cave, which had already been darkened, actually appeared, first weak, then expanded, and finally with a gradually enlarged light, everyone saw thick smoke and a sharp rise in fire.

But it turned out that it was the hot flare splashing and sparks, igniting the things in the cave opposite.

As the fire flourished, the burning range was also from far and near, and I saw the billowing smoke overflowing the cave opposite, and with the cold and dark wind blowing from the upstream in the dark river, it blew downstream into the underground.

The smoke was thick and was blown away by the dark wind of the dark river, which plunged into the ground like a dragon swimming into the sea not far below.

There was no room for the smoke to drift away downstream, so the smoke gathered more and more, and slowly filled the sky over the dark river, and with the change of the yin wind from time to time, the smoke accumulated into smoke and gradually swarmed upstream.

After a while, the position where everyone was already thick smoke was billowing out, and their vision was blocked, and they could no longer see the cave on the opposite side. It's just that the fire is blazing, and the bright and dazzling fire can still shine through the smoke.

At this time, Cao Longxuan made a move that surprised everyone, he suddenly took off the gas mask that had just been replaced with a new poison filter from his head, and sniffed hard in the steaming air.

The crowd was puzzled, so they heard him say: "There is oil in the cave opposite, or natural gas, underground marsh, and other combustibles. ”

When everyone saw him say this, they all took off their gas masks and sniffed, and sure enough, it was the smell of exhaust gases and soot produced after fuel combustion.

Everyone put on masks and asked puzzledly, could it be that the owner of this tomb actually used the crude oil underground?

A sinister burning trap was designed for everyone on the opposite side, leading everyone to trigger the mechanism to burn everyone? It's so bad!

Cao Longxuan shook his head, indicating that he didn't know.

It seems that there are piranhas and fire traps in front of them, and they can't easily pass through until they are detected.

In fact, on both sides of this underground dark river, on the side of the people is the stone dam that connects the karst cave, this stone dam is high and low, left and right, and the dogs and teeth along the line are intertwined, which is the masterpiece of nature.

In the upper reaches of the large drop in the river not far ahead, the river began to turn about a ninety degree bend in the direction of the left hand of the people.

After turning left along the river bank, everyone walked less than 100 meters, and saw a dark thick stone pillar standing in the river, like the mythical "Dinghai God Needle", in this gloomy environment, there is a kind of domineering and weird coexistence.

When you get closer, you can see that it is actually spinning constantly, and it turns out that it is using the huge flowing power of the river to drive the part of it that sinks into the water to rotate constantly, thus causing the whole to rotate.

The lower end of it is not in the river, and the top end is the roof of the cave above the river.

Through its material, the state of rotation, everyone has understood that this is the main pillar of the "torture scale".

It turns out that this balance is connected to this underground river through the bottom of the pit, and it is no wonder that after thousands of years, it can still rotate endlessly.

At the time, I thought it was unbelievable, thinking that it was simply a creation of God, and it was not designed and manufactured by human beings.

But now it seems that it is not so profound and subtle, as long as the materials are properly chosen, then the design and construction are not very difficult, as long as the water of this dark river does not dry up, then this huge balance will never stop spinning.

But then again, it's easier said than done, and that's what ordinary people often say. It is also true that this balance seems simple, but it is very difficult to implement.

Its most ingenious thing is that the balance is designed on the dark river, the river provides a steady stream of power source, the uniqueness of this idea, and the precise grasp of the position, the reasonable structure and the careful layout, together, can be called a genius!

Looking at the amazing design in front of them, everyone was a little dazed, after all, it is one thing to dare to think, only to make it and succeed is to be admirable.

Bai Yunfei said these thoughts, and Cao Longxuan also nodded again and again:

"The owner or designer of this tomb is indeed a genius of the heavens, and it is still not shocking that the light can come up with this power of using the power of the underground river to drive the balance to move endlessly.

However, in the vast Gobi Desert area of Dunhuang, the location of the underground dark river can be calculated according to the terrain and the feng shui situation, and it can be used according to the situation.

I have to admire that he is really an immortal talent. ”

Everyone sighed and began to think about what to do next.

The crowd gathered around the yellow paper that had been molded up, and referred to the drawings on the map of the camel rider's ancestors, and saw that there were no mistakes, and all of them were compared, indicating that the picture was not only true, but also correct.

Then, according to the marks on the map, the position of the symbol of the woman should be this natural cave. And the symbol that has not yet been explored in the picture, only the last one remains, that is, the place with the symbol of "sub-waist gourd" has not been found.

As expected, the area represented by this symbol should be the real place where the coffin of the tomb owner was kept.

Moreover, judging from the current situation of the burial chamber of the four coffins in front, the symbols representing these four coffins are also painted on the map, and the last place that has not been found is also marked with a rectangle painted in the "gourd" symbol.

From this, it can be concluded that the painted rectangle is the coffin of the tomb owner.

But where is this coffin?

After studying for a long time, there is no big eyebrow, after all, unlike any previous place, there are passages connected, which can be easily compared with the symbols on the map.

Suddenly, this place broke away from the passage and entered an empty and vast karst cave, and tens of billions of years of creation made this place full of complex landforms and features, and suddenly lost the direction of the target.

According to the marks on the map, this unsearched place is also on that vertical line, but I don't know what the position relationship between them is, and I can't judge the direction from the map.
