At this time, everyone suddenly felt that something was wrong.

I don't know if these far-north vipers were choked by the overbearing poisonous smoke of sulfur, or what, I thought they would retract into the hole when they smelled more pungent and intense smoke, but now it seems that they have smoked out those dormant in the depths of the cave.

Knowing this, it would have been better for everyone to venture through the pit without igniting the brimstone, at least there would be fewer snakes.

The situation is too frightening and speechless.

All the poisonous snakes are out of the hole, and it is estimated that even those old, weak, sick and disabled snakes and grandchildren have appeared, is this the great migration of species played in "Animal World"?

Everyone was shocked at that time, and suddenly realized that the situation in front of them was very bad.

This pit is so deep, there are so many snake holes, and the sulfur is also lit, if you can't get out, as long as it takes a long time, it will be buried here.

Several people went up, down, some on the rope, some had already climbed to the boom, and even Cao Longxuan and Sun Er had slid to the bottom of the pit along the sloping broken beam.

This has really become a dilemma.

It is not necessary to let the heavens and the earth be unspiritual.

Hanging halfway through this, all of a sudden countless poisonous snakes came out like a dense tide, how should this be?

I don't know who shouted in the nervousness, and everyone looked up and down, left and right, and they all saw the critical situation at this time.

But there is no turning back from the bow, and since he has chosen to get out of the predicament in this way, he can only continue to take the risk.

Besides, even if you go back, it's still a dead end.

So Bai Yunfei and Thirteen on the rope, as well as Su Lao Ghost on the inclined broken beam, all gritted their teeth and shouted and moved down.

But the more anxious I was, the more I couldn't get up fast, but I was quite embarrassed.

When everyone went down to the bottom of the pit, the pit was already full of smoke and heat.

Fortunately, the smoke and heat are spread upwards, and it is better at the bottom of the pit.

Perhaps it was the poisonous snakes on the dome and the four walls that could not stand the smoke and could not stand it, so they braved the opposite law to escape from the hole and gathered at the bottom of the pit.

At this time, the scene was extremely chaotic, and the people had to fight the poisonous snakes on the ground to prevent them from coming and hurting people, and at the same time they had to carve a way under the entrance of the passage where they came.

After all, the spikes all over the ground are too dangerous, and once a person falls on it or trips and sits on it, he will be pierced into a hedgehog.

In addition, the crowd had to try to hold on to the crumbling inclined boom and half-section of the beam to prevent it from collapsing, so that people could go up and escape.

The most frustrating and frightening thing is to constantly deal with poisonous snakes that rain down from the dome and stone walls.

These poisonous snakes fell down "crackling", some fell on everyone's heads, some fell on their shoulders, and some hung on their arms.

It was chilling and trembling, and they didn't dare to move them, but they had to reach out and pull them off and throw them out.

Fortunately, they were now choked by the poisonous smoke of the brimstone, and the blazing flames and hot vapors were scorching wildly.

Driven by the instinct to survive, he had to flee in all directions, forgetting to hurt people for a while, so no one had a new venomous snake bite for a while.

At first, everyone had to stop what they were doing, suspended their escape plans, cursed, shouted and repeatedly threw the falling poisonous snake to the ground.

But there were so many poisonous snakes that it was really as dense as rain, and as soon as one was thrown, at least two or three of them would fall on him, and later he would be full of poisonous snakes.

If this continues, even if the poisonous snake does not bite everyone, the fire is getting bigger and bigger, the poisonous smoke is getting heavier and heavier, and sooner or later everyone will die at the bottom of this pit.

At the critical moment, everyone is not even in the mood to curse, shout and throw snakes, and now it is imperative to escape from the bottom of the pit as soon as possible to avoid being burned to death by poisonous smoke and the connected fire.

Although the faces of the people were covered with gas masks, their filtering function had long since failed, and could only be used to relieve the uncomfortable effect of the flames on their faces, and to slightly alleviate the damage of smoke to their respiratory tract and eyes.

In this way, several people were covered with poisonous snakes, and from time to time poisonous snakes fell from above.

But there's no time for anyone to pay attention to that.

The lesser of two evils, everyone pushed and held the boom from falling, and inserted an iron drill into the snake hole on the other side, where the boom hit the bottom of the pit after it fell, above the broken pallet.

The iron hammer stuck to the bottom of one side of the boom, and several people worked the other side, pushing it with all their might to prevent it from toppling.

Then let Niu Gang borrow another iron hammer in his hand to insert it into the snake hole to help, and quickly climb up so that he could catch the rope as soon as possible.

But people are not as good as heaven, as the fire of sulfur burning gradually increases, it is not only poisonous snakes that fall downward, but also hot sulfur fireballs like dripping candle oil.

These extremely hot sulphur fireballs are liquid substances that have melted and burned with sulphur, and while they are simmering, they emit a faint blue light and fall more and more like raindrops.

Falling on people's clothes or backpacks not only ignites the clothes immediately, but also burns people to the point of screaming.

This torture of burning the body is extremely painful, and it has always been the most cruel punishment, so all kinds of burning at the stake have emerged in an endless stream throughout the ages.

Everyone was racing against time to get out of this huge pit as quickly as possible, but they never thought that the harm of the poisonous snake could no longer be taken into account, but they were trapped by the fire and could not get out.

The sulphur belt along the rock wall of the giant crater was burning fiercely at this time, and the liquefied sulphur flames that were dripping like raindrops almost formed a waterfall of fire droplets.

The crowd could no longer stand under the stone wall, so they had to howl helplessly and beat the flames on their bodies and retreat from the edge of the stone wall.

At this time, when I looked up, I saw that the rope that had been tied to the damaged tray had been ignited by the dripping fire liquid and began to catch fire.

If you don't have this rope, you can climb it by inserting the snake hole with an iron hammer, but it's too slow.

Not to mention whether they can survive the life and death of the smoke, just those poisonous snakes who have been choked crazy by the fireworks can't resist it.

These cold-blooded reptilian beasts had been cornered by the rain of sulfur and flames that had dripped and fell around them.

Some of them saw a fire-free space within the wall of fire from which two intermittent gasoline canisters had fallen, and out of biological instinct, they began to bypass the disjointed wall of fire and rush towards the middle of the fire-free zone.

Even some of them climbed slowly, and they were pressed by the poisonous snakes behind them, and they were entangled, which was really three layers inside and three layers outside.

Between the fire and the smoke, thousands of snakeheads flocked, and the smoke of the heat wave rose.

The sound of crackling and burning was mixed with the rustle of thousands of poisonous snakes crawling, and even the grinding of the teeth of the poisonous snakes that were choked madly by the fireworks, and the rapid and heavy breathing of everyone holding back in their gas masks like pulling bellows.

Everything is like coming to the abyss hell where 100,000 karmic fires devour and burn the soul, even if there is no physical pain, the pressure and impact on people mentally alone is already extremely huge, and if the will is very weak, the next moment will break down and die.

At the last moment, I saw Cao Longxuan take out the only remaining can of fluorescent bomb from his backpack, throw it upwards with force, and finally exploded on the sulfur belt under the mouth of the passage.

The luminescence principle of ordinary glow sticks is that peroxides and ester compounds react, and the energy after the reaction is transferred to the fluorescent dye, and then the dye emits fluorescence.

Although this kind of fluorescent bomb is called a "bomb", it is not filled with flammable or even explosive gunpowder, but phosphoramide ester compounds, which are diametrically opposed to the flammability characteristics of general ester compounds, and it has flame retardant properties.

So Cao Longxuan may have thought of this in a hurry, and he tried it temporarily, but it actually worked.

The burning sulfur was covered with a layer of fluorescent liquid from the fluorescent bombs, which isolated the oxygen, and the fire weakened a lot.

The time was approaching, and everyone hurriedly waved their arms, trying their best to shake off the poisonous snake that was still falling, and ran to the mouth of the passage.

Holding on to the boom again, Niu Gang inserted an iron drill into the snake holes, and climbed up a few meters as if he were dead.

Finally, I grabbed the rope that had been tied to the pallet to adjust the weight of the weight, and climbed up quickly and safely.

This rope had already been ignited by the sulfur flame, so that the fluorescent bomb exploded, the flame on the rope was extinguished, and it was also covered with a layer of flame-retardant fluorescent liquid, which finally did not burn out.

At this time, the people below have been choked by the fireworks and dizzy, their breath is suffocated, especially the burning sensation from their legs, it seems that their pants are about to be roasted.

The burning pain in the flesh relieved the dizziness that made people faint, but it also made people feel painful, and some of them couldn't stand it and began to howl.

There is a saying that "the leaky house coincides with the overnight rain", and often the more unlucky people are, the more things will happen to you.

Suddenly, Old Ghost Su shouted in horror: "Ah, black oil, there is actually black oil!" ”

Hearing his words, everyone's hearts were already filled with thoughts of discouragement, and they didn't want to look up and around, they wanted to burn here directly, such thoughts had already occupied their brains.

However, the unwillingness in the heart and a fierce courage arose from the side of the guts, and everyone stared at the blood-red eyes and looked up sharply, only to see black crude oil coming out of each snake hole.

I don't know if the oil from the branch of the oil vein in the ground was used by this genius and damned nameless, or if he got it from elsewhere and poured it into the snake cave in advance.

In short, Bai Yunfei guessed that when the boulder launched by the "anti-crossbow catapult" broke the central pillar of the scale, the hidden mechanism must have been activated, and the oil was already "ready to go".

As long as anyone dares to light the sulfur, the camp will be set on fire and the fire will be lit with gunpowder fire, which will trigger the release of oil.

This whole set of design is extremely sinister, ruthless and abnormal, and there is no last resort.

Fortunately, at this time, Niu Gang threw the rope from above, and everyone pushed Old Ghost Su up first.

After all, he is old, and he has been poisoned by snakes, so let him go up first, so as not to be at the bottom of the pit for a long time, unable to hold on, and appear three long and two short.

With the help of everyone's thrust, Su Lao Ghost gave full play to his skills over the years, turning deep mountains, wading in evil waters, raising mounds, and drilling tombs, dragging the rope and using his hands and feet at the same time, and climbed up after a while.

After Su Lao Ghost went up, he also threw down a rope, and quickly tied his end to the stone tablet engraved with the words "torture balance", and then went to help Niu Gang pull the rope in Niu Gang's hand.

In this way, there are two ropes to climb at the same time, and everyone can escape from the bottom of the pit twice as quickly.

Bai Yunfei and Cao Longxuan pulled the rope tied to the stone tablet, and quickly climbed up at the same time, one after the other.

The two of them almost didn't need other assistance, they didn't need to wrap their legs, pedal, or reach out to pick the snake hole on the stone wall to borrow strength, it was completely a special forces, scouts, and special police, and the rapid climbing action of urban anti-terrorism.

Through this, it is not difficult to see that Cao Longxuan's physical fitness, adaptability and physical state are not much worse than Bai Yunfei, who was born in special forces.
