Chapter 288

Even the police next to him couldn't help but look at him with admiration. This sinkhole is bottomless, and ordinary people's legs would tremble when they walked to the front, let alone go down in person.

Although it was close to 11 o'clock in the morning, saving people was the priority, and no one present knew geography.

The most important thing is that the first sinkhole was dug by him, and he has the obligation to go down to save those people.

Time passed minute by minute, and the firefighters were rushing up the mountain under the guidance of the villagers.

Not long after, they appeared in front of everyone, each of them carrying a large bundle of safety ropes.

On the way here, they had already heard the police describe the process and rescue plan of this accident.

After arriving at the scene, they simply greeted and immediately started preparations.

Looking at the hole that looked like the gate of hell, several firefighters' faces were a bit pale.

They are also human, of course they will be afraid.

But now they can only bite the bullet and go down to save people.

However, when they learned that Fang Yang was going down with them, the haze in their hearts swept away a lot.

Because they all know that Fang Yang's move is a sure thing!.

The firefighters found a few very thick big trees nearby to tie the descent ropes and safety ropes.

In the case of not knowing how deep it is, they can only descend little by little through this stupid method.

Fang Yang was the first to go down in the first batch.

Also accompanying were the cameraman and three firefighters.

Looking at the dark sinkhole, the cameraman shivered.

Even knowing there was a safety rope, he didn't dare to look down, gritting his teeth to tie the descender and carrying the camera to descend at a constant speed.

During the descent, Fang Yang saw many scattered stones on the straight pit wall and shouted: "Everyone, throw away the stones on the road. I don't know how deep this sinkhole is. If one falls down and hits the head, it will be like a cannonball."

Everyone nodded. Although they all wore safety helmets, at this height, the helmet would be like an eggshell.

Fang Yang tentatively threw a fist-sized stone down and counted silently in his heart.

It took a full 23 seconds to hear a faint falling sound, which made everyone feel a bit uneasy.

Based on this time, the depth below should exceed 400 meters.

At such a depth, even Fang Yang felt a bit bad.

A big question mark was placed on whether the four villagers who fell down before could survive!

There was no time to care about much, so they could only control the descender to descend slowly.

During the descent, the strange calls in the cave became clearer and clearer.

After this period of time, the cameraman's psychological quality had also become much stronger, and he even dared to point the camera down to film.

Suddenly he seemed to see something and shouted at Fang Yang: "Brother, look at what's on the wall below?"

Fang Yang fixed his eyes and saw many black shadows flying in the dark cave.

"So many bats?" The firefighter next to him exclaimed!

"No!" Fang Yang shook his head and looked while descending slowly, and the system panel popped up immediately.

"Not bats, it's a kind of bird, called swiftlet! Look closely at the wall, there are many white things on it, see? Those are the legendary bird's nests!"

"Bird's nest!"

Everyone exclaimed!

Everyone has heard this name, but they don't know what the bird's nest looks like.

Only know that the bird's nest is a tonic, a nest built by swallows with saliva.

Today is also their first time seeing the true appearance of a bird's nest.

Although several people continued to descend, the birds were flying around densely below the cave.

The bird's nests on the wall were even more numerous, making the scalp numb.

It made people's dense phobia about to commit.

The cameraman looked at this scene and clicked his tongue in wonder, holding the camera and filming constantly: "Brother, why do you say they want to live in such a deep place, can they see?"

Fang Yang smiled: "That's because swiftlets are similar to bats, and they all rely on echolocation to navigate. In other words, they can come and go freely even in the dark."

When they descended near the bird's nest, they specially stopped to look at the appearance of the bird's nest.

Snow-white embedded on the cliff, crystal clear, just like small teacups.

Looking at the dense bird's nests below, the cameraman seemed to have fallen into the eyes of money: "If all these are brought back, wouldn't it be a fortune!"

Fang Yang glanced at him: "Think too much, these bird's nests are made by swiftlets with their own saliva, each one takes more than a month to spend, it can be said to be painstaking. The reason why bird's nests are expensive is because it is difficult to form, and the collection risk is extremely high. If you are not careful, you will easily fall to death. Let's go down and save people quickly!"

The further down, the darker the light, and everyone didn't know how many meters they had descended.

But they could vaguely see some reflections below.

Several people knew that this should be the reflection of the underground river.

At the same time, they all breathed a sigh of relief. As long as there is an underground dark river, it must be connected to the previous sinkhole.

This also means that it is the right choice for them to go down from here.

After passing through the swiftlet's nest, they soon felt that their feet were no longer suspended, but stepped on the ground.

Looking up from below, the entrance of the cave became very narrow, and only a beam of light could be seen shining in.

But their surroundings were already pitch black, and they could only vaguely see some things.

As Fang Yang analyzed, this is a karst landform, and the bottom of the sinkhole has been hollowed out.

Several people looked up to observe the surrounding environment, and the cameraman exclaimed: "Brother, look at the wall on the top of the head, what is that?"

Fang Yang looked up and saw a blue starry sky on the top wall of the underground karst cave.

It looked particularly beautiful in the dark environment.

The dense small light spots were like stars in the sky, shaped like a vast galaxy.

Even the firefighters next to him were attracted by this beautiful scene and couldn't help but exclaim.

"Is this an illusion? There is a starry sky underground?"

But Fang Yang recognized what this was at a glance through the system.

"This is not a starry sky, but a kind of insect!"

"Bug?"

Fang Yang nodded and took out the searchlight he had prepared in advance and shone it up.

Under the huge beam of light, the cave roof that was glowing blue appeared with crystal clear sticky threads like pearl curtains hanging vertically from the cave roof.

It looked even more beautiful than the blue starry sky just now.

Just as several people were admiring, Fang Yang explained: "Don't look at them as beautiful, but these are fatal traps. In this dark environment, animals must adapt to the survival environment here."

"For example, this pearl curtain in front of me is made by cave fireflies. The glands in their mouths can secrete mucus. Every time they spit, it forms a pearl shape, and one by one they stick together to form a pearl curtain, hanging on the top of the cave."

"Every cave firefly will spit out many such pearl curtains, just like a spider weaving a web. When all the steps are completed, it will hang itself up with mucus, and then like fishing, emit blue starlight to attract prey to the door."

After listening to Fang Yang's explanation, everyone's scalp felt numb.

Sure enough, the more beautiful things are, the more dangerous they are.

【Popularity】 +1+1+1+1.

——【Damn, I once thought Fang Yang and the others came to the world of cultivating immortals, there are avenue stars here, but it turned out to be fireflies after a long time. But to be honest, this thing is really beautiful. I have seen this decoration style before, and I guess it evolved from this!】

——【This sinkhole is really deep! I really admire their courage, they came down as soon as they said. For this kind of dark and enclosed space, I will have a physiological reaction once I go in, dizzy and want to vomit, and can't stand it at all. Not kidding, even if you give me 100,000 yuan, I won't consider it.】

——【The first time I saw what a bird's nest looks like, but what's good about this thing, it's all swallow's saliva, and it's treated as a tonic? How tonic can it be! Can you live a few more years after eating it, or can your body be much better after eating it? I wouldn't eat this thing if you gave it to me, thinking that it was made of bird's saliva, I couldn't swallow it at all.】

——【I feel that those few villagers are ominous, falling into such a deep sinkhole, it would be a ghost if they could survive. Look at the stream below, it's only so shallow, what's the difference between falling down and falling on the ground, even if they are at a low altitude, there are dozens of meters, right. I hope they can hold on!】

Fang Yang held the searchlight and turned around to observe the environment.

There were stalactites and stalagmites everywhere on the wall, and occasionally water droplets could be seen dripping from the wall.

These stalactites are formed by limestone. After years of groundwater infiltration, nature is like a sculptor, carving cave scenery in various poses and with different expressions drop by drop.

A small stream can be seen flowing constantly on the ground.

There are also many sandy lands exposed, and walking on them will not sink too deep.

Judging from the surrounding walls, there are very deep water marks.

It is obvious that the water depth here should have exceeded 1 meter at the deepest point.

But now only this thin stream is left, most likely because the mine shaft dug to the underground layer, which directly led to the water flow of the dark river being drawn away.
