When one of the trays turned to everyone's feet again, Cao Longxuan pressed the tray with the Luoyang shovel assembled by Su Lao Ghost.

I saw the huge, bulky, seemingly very stable tray sink down sharply after being stressed, and then the two pallets undulated symmetrically like seesaws, but continued to rotate without stopping or changing speed in the slightest.

"It's very well balanced, and it sinks down with a little force." Cao Longxuan's face showed solemnity.

Old Ghost Su bared his teeth, scratched his gray hair, and made a very terrifying joke: "It seems that this is a human flesh without beef, and after weighing, throw it to the bottom of the pit to feed the mice." ”

Bai Yunfei asked Old Ghost Su: "What do you mean is that you must use this balance tray to measure things like something before it is possible to pass?" Is it possible to find another way? ”

Old Ghost Su squinted his eyes, looked up and down, left and right repeatedly, the giant pit and the rotating scale, and shook his head:

"A passage at the end of the good end, it is hard to wear an iron chisel through the mutton skewers, and put on one of these in the middle, it seems that if you don't use it, you don't want to go over."

Bai Yunfei didn't dare to step on the scales easily, after all, after Cao Longxuan tried it just now, everyone understood that if there was no heavy object on the tray at the other end, and he rashly stepped on this side of the tray, the consequences would definitely be unimaginable.

And since it is a balance, Bai Yunfei thinks that the tray opposite must also be an object of the same weight, otherwise if the weight is different, it will be tilted, and what is the consequence of tilting, Bai Yunfei looked at the white bones at the bottom of the pit again, and naturally understood.

So Bai Yunfei took out a bundle of mountaineering ropes from his backpack, tied one end to Bai Yunfei's waist, and then patted Niu Gang, who was still stunned, and motioned him to pull the rope.

Niu Gang obviously took such a shot from Bai Yunfei to ease his stunned strength, so he shouted:

"His grandmother's legs, what the hell is this? What's the Ferris wheel in a playground? Where is the pimple of the ticket seller? Damn, I didn't think about it for a long time and didn't figure out how to get past without it. ”

It's not like that, what's the matter? Bai Yunfei directly punched him and told him to hold on to the rope. "What are you doing? Why are you going down? Niu Gang asked puzzled.

"No, Bai Yunfei wants to go down to this pit to see if there are any hidden passages or something. You have to pull Bai Yun Fei, if Bai Yun Fei doesn't gain anything by the edge of the pit, try to go on again, and then you must hold it, don't make any mistakes. ”

After speaking, Bai Yunfei glanced at Cao Longxuan and the others at Niu Gang.

Although Niu Gang is very straightforward and honest, he is not stupid, and when he saw Bai Yunfei glancing at him, he understood what Bai Yunfei meant.

nodded immediately, and his voice raised a little: "Don't worry, Lao Bai, as long as I am here, no one will dare to attack you!" ”

A few people who were still observing this huge and weird balance heard the conversation between Bai Yunfei and the others, and they all turned to look at everyone.

Bai Yunfei explained: "This place is strange and weird, the environment and things are difficult to guess with common sense, we are now in a situation where we can't figure out the way, so we must see clearly first, grasp more useful clues, otherwise there is no way to move on to the next step." ”

I only heard Cao Longxuan laugh and said, "Yunfei, let it go, as long as it is not under uncontrollable circumstances, you can act boldly." Rest assured, since we are already on the same warship, we must work together and work with one heart and one mind, and we must and can only support each other, not calculate each other. ”

Bai Yunfei glanced at him and said, "It should be so." ”

Then he moved left and right along the edge of the huge pit, using a flashlight to look at the bottom of the pit in front of everyone's feet, as well as the façade of the deep pit, hoping to find a hole or something.

If it can really be discovered, it is estimated that it may be the way out of another village, which is better than having to use this extremely dangerous and strange scale.

However, Bai Yunfei crouched on the edge of the pit and watched for a long time, except for the dense terrifying spikes at the bottom of the pit, and the standing wall was full of as many holes as on the dome, there were no big holes.

Bai Yunfei didn't give up, and he also lay on the edge of the pit several times to visit, during which he had to keep observing the tray that turned from time to time to prevent him from hitting his head.

After the pallet turned over, Bai Yunfei pulled the climbing rope held by Niu Gang, climbed the edge of the pit and tentatively slid down the pit wall, and decided to descend to the bottom of the pit to continue searching.

When Bai Yun flew to the edge of the pit, he smelled the smell of sulfur and began to be strong, especially pungent.

When Bai Yunfei climbed the edge of the pit and was about to slide down, he saw that Thirteen and Sun Er had pulled the rope to prevent Niu Gang from being unable to pull it alone, which made him feel a lot more relieved.

And just when Bai Yunfei climbed the rope and slid down to the level of the pit, he saw that a horizontal circle along the edge of the pit was actually a whole annular sulfur belt around the huge pit, just like painting the wall.

The sulphur is about 2 meters high and is on the same level as the two horizontally rotating balance pallets.

It is this sulphur belt that exudes a strong smell of sulphur.

At this time, Bai Yunfei was hung in front of this sulfur belt by a rope, which made his nose itch, his nasal cavity tingled, his eyes were hot, and he wanted to sneeze and tears.

In the week of the stone passage, there is a circle of sulfur around the entire passage, which communicates with the horizontal annular sulfur belt of the whole pit, but it is self-contained.

I think there must be such a ring of sulfur around the passage hole on the opposite side.

But looking at this regularly shaped sulfur belt, it must have been artificially laid by the builder, how could there be such a rule in nature?

In addition, sulfur has no very special formation conditions and unexpected causes, it is basically formed by huge high-temperature geothermal heat underground, and what can appear on the surface is mostly the crater of an active volcano or an extinct volcano, which is naturally formed after a volcanic eruption.

Of course, there are also tens of trillions of years ago when geological movements created sulfur-rich ores that were exposed to the ground or stored in known exploration caves.

But no matter what the cause, it will not have such a regular shape, and this is neither a crater nor a vein.

The sulphur is certainly not natural, but must have been installed artificially.

So a question came to Bai Yunfei's mind, what is the use of laying sulfur on the wall of this huge pit that suddenly appeared in the passage?

Could it be... A bad premonition flashed through my mind.

Just as Bai Yunfei was staring at the sulfur belt in front of him, frightened by this thought, he heard several people on the edge of the pit exclaim: "Quick, come up, there are snakes!" ”

The content of these exclamations happened to coincide with the flash of thought in Bai Yunfei's heart at that time.

Bai Yunfei hurriedly swept the flashlight downward, and was horrified to see that under the sulfur belt in the circle of the passage entrance, snakes with earthy yellow and black spots began to drill out of those holes.

Some have just poked out the snake's head, while others have already crawled out of the hole and started swimming, as if looking for a target.

Bai Yunfei was so shocked that his palms were sweating, and he felt that he couldn't hold on to the rope and fell down.

Seeing those wriggling snakes, his scalp was numb, and he pulled the rope and ran up with all his strength.

Fortunately, the location of the feet is the junction of the sulfur belt and the pit wall, and there is not an area with holes, so no snake can touch Bai Yunfei's legs and feet for the time being.

So as soon as his feet stepped on the stone wall, and then borrowed the power of pulling up, he instantly jumped onto the edge of the pit.

Several people on the edge of the pit reached out at the same time, grabbed Bai Yunfei's arms and clothes, and pulled Bai Yunfei back to the ground of the passage like a turnip.

Although it was only for a short moment, Bai Yunfei's heart was beating rapidly, and he felt like he was about to jump out of his throat.

When he was gasping for breath in shock, Bai Yunfei realized that not only the palm of the hand pulling the rope, but also the cold sweat all over his body.

When I was a soldier in the special forces before, I was never so nervous about facing terrorists.

Seeing so many snakes crawling out of the pit wall on this side of the stone passageway, everyone was frightened.

Sun Er said in a panic: "Old Su, this is to let everyone feed the mice, this is obviously to feed us to the snake!" ”

Old Ghost Su shouted in surprise, "How can there be so many Arctic Vipers? This goods like to live alone.,It's usually not a pile of drops.,This... This is to welcome us today, gather for a welcome party? ”

Cao Longxuan nodded:

"Su Lao is right, this is indeed the Arctic Viper, there are many in Xinjiang, after being bitten by it, it will be swollen, dizzy, vomiting, and the symptoms are the most serious in about six hours, but it is rarely fatal.

However, it is a bit strange that they can form groups instead of hibernating.

Because this snake is basically in a group state only during the hibernation period, and when it does not hibernate, it is basically in a state of solitude. ”

Everyone used flashlights to shine at the bottom of the pit, and with the light of the glow sticks, they saw that the poisonous snakes below began to appear densely.

Everyone couldn't help but be frightened, and there was always a very repulsive and disgusting feeling, as if these snakes were crawling on their own skin, and they were extremely uncomfortable.

Everyone saw that Cao Longxuan knew more about this kind of snake, so they asked him to introduce it in detail.

"The Arctic Viper, mainly distributed in the forest-steppe areas of Central Asia and North Asia, the mountainous areas of northern and central Europe, as well as Xinjiang, Jilin and other places in China, mostly lives in temperate and cold forest areas and grassland meadows, etc., is the most common venomous snake in central Europe, and is also the only venomous snake in the United Kingdom.

It is the only snake found in the Arctic and inhabits a variety of areas, from forests and dunes to swamps.

Generally, snakes hibernate when the temperature is below 10 °C, but the Arctic Viper can still move when the temperature is as low as 3 °C, and it is the only snake that appears in the Arctic Circle, so it is called the Arctic Viper.

This snake does not attack people easily, and after being bitten by a northern viper, there will be severe pain near the wound, and after 20 minutes, there will be a more serious reaction.

Victims experience swelling, dizziness, vomiting, but the worst symptoms do not appear until six hours later.

Far North Viper bites are rarely fatal – only 13 people have been killed in the UK since 1900, and only 13 people have died from Far North Viper bites since 1900, one of them because of an adverse reaction to the antidote. ”

Cao Longxuan spoke eloquently, which shows that his knowledge is rich, which is admirable.

Although Cao Longxuan said that being bitten by this snake is rarely fatal, it does not guarantee that all of them are not fatal.

And, not to mention whether they are poisonous or not, just looking at the patches of poisonous snakes wriggling there makes people feel frightened and disgusted.

The most important thing is that being bitten by a snake may be less venomous, or the amount of venom is not enough to kill, but so many snakes are like snake nests, if they bite all the fangs into your flesh, no matter how low the toxicity is, it is difficult for you not to die.

Bai Yunfei was frightened a lot just now, so he was not only afraid of these poisonous snakes, but also had some hatred, so he said with some distraught:

"I think this is forcing us to walk the scales and not let us pass under the pit. This design is also vicious enough! ”

"Damn, it's a big deal that my old cow threw a few gasoline bombs at it and burned these poisonous snakes to death." Niu Gang scolded indignantly.

Cao Longxuan and the others all glanced at each other at the same time, this was an expressionless glance, but it was precisely this expressionlessness that made people uncomfortable, because expressionlessness can often be regarded as "contempt".

Niu Gang is not stupid, he was a little angry by this kind of look, and he stiffened his neck and said, "What's the matter, what are you looking at?" ”

Sun Er said helplessly: "Brother Niu, aren't you harming everyone? There were several cans of gasoline in their backpacks, just in case. It's really as easy to burn as you said, so it is estimated that there will be no more of these white bones underneath. ”

Niu Gang was a little stunned when he heard it: "What? Why has it become a harm to you to keep the land in order? ”

"You want to," Sun Er patiently explained to him:

"Even if you can burn a few snakes, you don't have enough gas to make sure you can burn all the snakes, right? But if you burn these snakes, they will make you burn them honestly? As soon as this experience hurts, it will definitely run around and crawl, and finally run to this brimstone and ignite the sulfur, what should I do? ”

Niu Gang's face collapsed when he heard this, and no matter how stupid his head was, he understood that these yellow sulfur belts were to isolate the snakes, and it was precisely because of them that the snakes were prevented from crawling out of the giant pit and surging into the passage.

If he really threw a few gasoline bombs, not only would he not destroy this huge number of snakes, but it would also be very likely to ignite the sulfur belt, without the sulfur belt, those snakes would lose control, and the unlucky ones would only be everyone.

The thirteen said, "Why don't we shoot pitons and use climbing ropes to cross over from above?" ”

Everyone looked up along his lines, but immediately rejected his proposal.

The dome of the entire semicircular arc was full of holes, exactly the same as the holes of the Arctic Viper crawling out of the bottom of the pit.

That is to say, when someone tries to cross over the scales, poisonous snakes will inevitably swarm on the dome, and although it is still calm above, there is no need to pay for it, and the result is inevitable.

It doesn't work down, it doesn't work up, it seems that there is only the middle lane.

But in the middle is this huge balance that spins endlessly, and although the balance between the upper and lower directions is very sensitive, the left and right directions are very stable.

This huge balance made of ink-black oil shale structure does not use a single metal part at all, and is completely the kind of living jointed mortise and tenon structure, which can ensure the flexibility of the upper and lower directions, and the stability of the left and right or horizontal directions cannot be shaken at all.

Everyone reached out at the same time, trying to pull the rotating tray boom part.

But to their despair, there was nothing they could do to stop it.

The abominable scales continued to spin at their unwavering speed.

It can be seen that the power that pushes it to rotate is outrageously powerful.
