readx; The two rubber boats were inflated, and Ning Xiaofan also instructed Lao Wang to connect a rope to the first of the two rubber boats, so as not to avoid being separated halfway. After everything was put www.biquge.info ready, everyone did not delay, and after pushing the two rubber boats into the water, they boarded them one after another according to the prior arrangement.

Ning Xiaofan, Fatty, Hou San, and Zhang Chun shared a boat, and the rubber boat was prepared with two pulps, and it was not his turn to row the boat, and Zhang Chun and Hou San took over the strength of the oars. Now, of course, it's going down the river, and it doesn't take much effort.

This underground dark river area is relatively spacious, the water flow is not turbulent, people sit in the boat and feel very stable, not only that, both sides of the dark river are all kinds of strange stalactites, endless, magnificent, especially under the illumination of the helmet overhead light and the flashlight, the colorful light is refracted, it is even more pleasing to the eye.

It is no wonder that Xinao Group and the National Tourism Administration also have a cooperation agreement, not to mention whether the treasure can be found in the depths of this huge sinkhole, just with this huge and rare karst cave wonder, this place is also worth exploiting.

The stalactite wonders on both sides of the strait are gorgeous and colorful, Ning Xiaofan and his party are very novel, and they go down the river, while watching, pointing and discussing, and unconsciously falling into the magnificent wonder.

This underground river was much longer than expected, and before you knew it, more than an hour had passed.

With the quiet passage of time, no matter how beautiful the landscape is, there are times when they get tired of looking at it, Ning Xiaofan, Fat Man and others have withdrawn their gaze and no longer pay attention to the scenery on both sides of the strait.

There was nothing to do on the left, Ning Xiaofan took out the tablet and clicked on the coordinate positioning display map.

Through the screen display, you can clearly see several slowly moving green light spots, and there are seven light points in total, representing Ning Xiaofan's line of seven

The positioning coordinate map does not show the length of this dark river, and as for when the trip on this waterway can be ended, Ning Xiaofan is not clear. However, according to the current speed of the rubber boat, more than two hours have passed, and it can be roughly estimated that it has traveled more than 40 kilometers.

More than 40 kilometers, put on land is also a lot of mileage, this is only the outer area under the sinkhole. Ning Xiaofan didn't dare to imagine how big the area under this sinkhole was?

There seemed to be no end to the underground dark river, coupled with the sense of oppression brought about by the darkness and depth, as well as the sense of confusion about the unknown, Ning Xiaofan and the others couldn't help but feel a little up and down in their hearts, not like before, they chatted a few words from time to time, and they all fell silent.

The darkness was awe-inspiring, and the darkness was still moving, except for the occasional sound of dripping water and paddling, even if the overhead lights and flashlights on the helmets could not hide the quiet and eerie atmosphere.

The silence did not last long, and in the distance, the rumbling of water could be faintly heard, and at this time, the seemingly calm water gradually became turbulent.

At this time, the fat man came to Ning Xiaofan's side and said, "Xiaofan, something is wrong, did you hear the sound of the water?" There will be no overhanging terrain ahead

Ning Xiaofan frowned slightly: "No, if there is a hanging place, at least someone has to remind us before we go, I think, even if there is a suspended terrain, it will not be too high." ”

The fat man nodded and said, "Well, you have a point, but you still have to be careful, in case the terrain is high, we won't be able to eat and go around." ”

Ning Xiaofan heard him say this, thought about it, and immediately issued an instruction on the micro microphone pinned to the neckline: "Everyone pay attention, the water is turbulent ahead, pay attention to safety, and protect your equipment."

The instructions were clearly transmitted to everyone's ears through the headset, and Hou San and the others did not dare to slack off, packed electronic instruments and tablets and other items that were not easy to release water into the water release backpack, and then grabbed the safety belt on the edge of the rubber boat.

Not long after Ning Xiaofan gave the order, the rumbling sound of the water became louder and louder, and the water became more and more turbulent, and when people were on the boat, they not only felt the speed of the rubber boat suddenly accelerated, but also felt that the turbulent water had a certain inclination.

"I'll take a quick look, what's ahead?"

With the fat man's sudden call, Ning Xiaofan turned on the flashlight and stared ahead.

Through the flashlight beam, you can vaguely see a white flower water curtain in front of you, the water curtain is about five zhang wide, pouring down, not to mention a foggy water vapor, but also bringing out the sound of rumbling water.

At this time, the speed of the rubber boat was extremely fast, and in the blink of an eye, it was less than a meter away from the water curtain.

At this moment, the rubber boat suddenly sank forward, accompanied by the uncontrollable exclamation of Ning Xiaofan and others, the rubber boat suddenly fell out of control, as if falling into a cliff, and a sense of suspension came instantly

In the blink of an eye, the rubber boat slapped heavily on the turbulent water, bringing out a large splash. Before he could come back to his senses, the rubber boat soared violently in front of him, and the moment the feeling of hanging in the air hit, it fell down violently.

The water is turbulent, but not deep, and the layers under the turbulent water surface are layered on top of each other, forming a series of suspended rapids, and under the impact of the torrents, the rubber boat is completely out of control

What's it like to ride a roller coaster? Even if Ning Xiaofan and the fat man and others had never sat on it, they had also experienced the taste of the roller coaster at this time, and the rubber boat had lost control, and as the rubber boat fell, it soared and rushed towards the water curtain at a very fast speed

Fortunately, Ning Xiaofan reminded him in time, and everyone grabbed the seat belts so that they would not be thrown out of the runaway rubber boat.

"Not good," I don't know who exclaimed, and the curtain of water that made a rumbling sound was close in front of me

"Hold on" Ning Xiaofan just had time to shout, and the rubber boat carrying everyone soared into the air, and his head plunged into the water curtain.

Bang la blah

The pouring water curtain not only drenched Ning Xiaofan and the others, but also smashed the helmets with a bang, and smashed them one by one.

Huhu two rubber boats passed through the pouring water curtain one after another, and before he could breathe a sigh of relief, he felt the wind whirring in his ears, and a sense of suspension came instantly.

It's over, and the bottom is empty

As soon as this thought flashed in everyone's minds, they only heard a "snap", and the rubber boat under them fell heavily on the water, bringing a large splash

After settling down, everyone felt that the rubber boat was still, and then they realized that they were in the middle of a pool of water that did not know how deep, and when they looked around, there was a large grotto with a wide space around them, behind them was the curtain of water, and in front of them were several huge rocks and uneven cave walls.

Where is this?

Ning Xiaofan and the fat man couldn't help but glance at each other, and their eyes were full of palpitations.

"Xiaofan, are we on the ground?" The fat man asked.

"Should it be?" Ning Xiaofan himself was a little unsure.

The moment he rushed into the water curtain before, in his busy schedule, he noticed that there was a turbulent underground dark river in front of the water curtain, which was tilted down in front of the water curtain, and the drop was estimated to be five or six meters, but he didn't know where the turbulent underground dark river led?

At this time, Ning Xiaofan observed that the drop behind the water curtain was only three meters high, otherwise, he and the others would have been thrown out of the rubber boat if they couldn't figure it out.

I don't know when this pool of water was formed? The area is only 100 meters square, not big, but it gives people a sense of depth, in this space, even the sound of the water curtain tilting down is much smaller, it seems relatively quiet.

"Everyone's okay?" Ning Xiaofan, who calmed down, asked.

"It's okay, it's okay, let's all hold on to our seat belts." Hou San and others responded.

"Lao Wang, Xiao Shanzi, haven't we lost our backpack?" Ning Xiaofan asked again.

"I didn't lose it, I packed it all and tied it with the rubber raft, even if the raft overturned, I couldn't lose it."

Ning Xiaofan listened, his heart was slightly relieved, and said, "Since everyone is okay and has not lost any items, let's go ashore first and see if there is a passage." ”

The waterhole is not big, just a few strokes away.

When they arrived at the shore, everyone dragged the rubber raft ashore, the rubber boat could not be easily discarded, Lao Wang and Xiao Shanzi began to deflate the rubber boat, Hou San went to explore the road first, and the rest of the people began to take care of their bags and organize their belongings.

Everyone was wearing water release clothing, even if they were drenched with water, except for the water on their faces and exposed hands, only a drop of water was formed on the clothing on their bodies, which could not erode into it, and they could shake the water droplets off with just a shake.

Ning Xiaofan's backpack was carried with him, he took out the tablet from the backpack and checked it, opened the map coordinates, and then checked the coordinates he was in, and found that he and the others were not out of the main line, in other words, there should be a passage on the shore of this pool.

Sure enough, within a few minutes, Hou San returned and said that there was a passage on the ramp behind the rocks.

Ning Xiaofan glanced at his watch, starting from the base, by now, more than 4 hours have passed, and it should be almost lunchtime at this time.

Since there was a passage, Ning Xiaofan was not in a hurry to move forward, and immediately beckoned Lao Wang to prepare lunch.

Lao Wang and Xiao Shanzi are in charge of logistics, and this cooking work is naturally included. Among the logistics items that the two received this time, most of them were food, and as for drinking water, there was an underground river in the sinkhole, not only many tributaries, but also large and small karst caves with water, which was not lacking, so they didn't bring it.

Groundwater has been tested by early investigators, and is not only non-toxic, but also rich in minerals, and is a pure natural mineral water

However, for the sake of prudence, Ning Xiaofan still instructed Lao Wang and the others to test it with an instrument, and still throw a water purification pill when boiling water, so as not to make trouble after drinking.

There was Lao Wang and Xiaoshanzi to clean up lunch, and although Ning Xiaofan and Fat Man and others did not consume any physical strength along the way, they still found a flat place to seize the time to rest.

Of course, Ning Xiaofan already knew in his heart that once he entered the sinkhole, his life and safety were no longer protected by the law, and vigilance matters were indispensable, so he arranged for Chen Biao to serve as a temporary vigilance.

After resting for a while, with a burst of aroma wafting into his nose, he didn't wait long for Lao Wang to call everyone to dine.
