After the two rubber boats were fully inflated, Ning Xiaofan also instructed Lao Wang to connect the heads of the two rubber boats with a rope so as not to get separated midway.After everything was tidied up, everyone did not delay, and after pushing the two rubber boats into the water, they boarded one after another according to the prior arrangement.

Ning Xiaofan, Fatty, Hou San, and Zhang Chun took a boat together. The rubber boat was equipped with two oars, and it was not his turn to row the boat. Zhang Chun and Hou San took over the hard work of paddling.Of course, it's going downstream now, so it doesn't take much effort.

The area of ​​this underground underground river is relatively spacious, and the water flow is not turbulent. People sitting in the boat feel very stable. Not only that, both sides of the underground river are full of strange shapes of stalactites, which are endless and spectacular, especially in the helmet. Under the illumination of the ceiling lamp and the light of the flashlight, the colorful light is refracted, which is even more pleasing to the eye.

No wonder the New Australia Group and China National Tourism Administration also have a cooperation agreement, not to mention whether treasures can be found in the depths of this huge tiankeng, this place is worth developing and utilizing just because of the huge and rare cave wonders.

The stalactite wonders on both sides of the strait are gorgeous and colorful, and Ning Xiaofan and his party were very novel. They went down the river, watching and pointing at the same time, unknowingly falling into the magnificent wonder.

This underground river was much longer than expected, and before I knew it, more than 2 hours had passed.

As time passed quietly, no matter how beautiful the scenery was, there were times when they got tired of looking at it. Ning Xiaofan, Fatty and others all turned their eyes away and stopped paying attention to the scenery on both sides of the strait.

Nothing happened nearby, Ning Xiaofan took out the tablet, and clicked on the coordinates display map.

Through the screen display, several slowly moving green light spots could be clearly seen. There were seven light spots in total, representing Ning Xiaofan and his party of seven.

The positioning coordinate map cannot show the length of this dark river, and Ning Xiaofan is not sure when the journey on this waterway will end.However, according to the current speed of the rubber boat, after more than two hours, it can be estimated that it has traveled more than 40 kilometers.

More than 40 kilometers is not a short mileage on land, and this is only the peripheral area under the tiankeng.Ning Xiaofan couldn't imagine how big the area under this tiankeng was?

There seems to be no end to the underground river, coupled with the sense of oppression brought by the darkness and the sense of confusion about unknown things, Ning Xiaofan and the others are unavoidably agitated, not chatting with each other from time to time like before. After a few words, everyone fell silent.

The darkness is awe-inspiring, and you are still walking in the dark. Except for the sound of dripping water and the sound of oars from time to time, even if illuminated by the dome light and flashlight on the helmet, it still cannot cover up the quiet and weird atmosphere.

This quiet atmosphere didn't last long. In the distance, the sound of rumbling water could be heard faintly. At this time, the seemingly calm water flow gradually became turbulent.

At this time, the fat man leaned over to Ning Xiaofan and said, "Xiaofan, something is wrong, do you hear the sound of water flowing? There is no suspended terrain ahead, right?"

Ning Xiaofan frowned slightly: "No way, if there is an overhanging place, at least someone should remind us before we set off. I think even if there is an overhanging place, it won't be too high."

The fat man nodded and said: "Well, what you said makes sense, but we still have to be careful, if the terrain is high, we won't be able to eat and walk around."

Ning Xiaofan heard what he said, thought for a while, and immediately issued an instruction through the miniature microphone pinned to the collar: "Everyone pay attention, the water ahead is fast, pay attention to safety, and protect your equipment!"

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

Not long after Ning Xiaofan gave the order, the sound of the rumbling water became louder and the water became more and more turbulent. People on the boat not only felt the speed of the rubber boat suddenly increased, but also felt that the turbulent water had a certain degree of relaxation. slope.

"Damn! Look, what's in front?"

Following the fat man's sudden cry, Ning Xiaofan turned on the flashlight and stared forward.

Through the light beam of the flashlight, one can vaguely see a white curtain of water appearing in front of it. The water curtain is about five feet wide, pouring down, not to mention a misty water vapor, and there is also the sound of rumbling water.

At this time, the speed of the rubber boat was extremely fast, and in a blink of an eye, it was less than 20 meters away from the water curtain.

At this moment, the rubber boat suddenly sank forward and down. With 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 slammed heavily on the turbulent water surface, bringing out a large splash of water.Before he could recover, the front of the rubber boat suddenly jumped up, and the moment the feeling of being suspended in the air hit, it suddenly fell down again.

The water is turbulent, but not deep. The turbulent water is layered under the surface, forming torrents with suspended drops. Under the impact of the torrents, the rubber boat is completely out of control!

What's it like to ride a roller coaster?Even though Ning Xiaofan, Fatty and the others had never been on a roller coaster, they had experienced the roller coaster now!The rubber boat had lost control, and as the rubber boat fell, it jumped up and rushed towards the water curtain at an extremely fast speed!

Fortunately, Ning Xiaofan reminded them in time, and everyone grabbed their seat belts tightly so that they would not be thrown out by the out-of-control rubber boat.

"Not good!" Someone exclaimed, and the water curtain that made the sound of rumbling water was approaching!

"Hurry up!" Ning Xiaofan just had time to shout loudly, the rubber boat carrying the crowd soared into the air, and plunged his head into the water curtain.

Whoa!

The pouring water curtain not only drenched Ning Xiaofan and the others thoroughly, but also made the helmets rattle, and smashed all of them to pieces.

Hoo hoo!Two rubber boats passed through the pouring water curtain one after another. Before they breathed a sigh of relief, they felt the wind whistling in their ears, and a sense of suspension came instantly.

It's over!Below is empty!

Just as this idea flashed into everyone's minds, they heard a "click", and the rubber boat under them fell heavily on the water, causing a large splash of water!

Gathering their minds, everyone felt the rubber boats come to a standstill, and then they realized that they were in the middle of a pool of unknown depth. Looking around, there was a large grotto all around them, with the water curtain behind them, and a few blocks in front of them. Huge rocks and uneven cave walls.

This is where?

Ning Xiaofan and Fatty couldn't help but glance at each other, their eyes full of lingering fear.

"Xiaofan, have we reached the end of the land?" the fat man asked.

"It should be?" Ning Xiaofan himself was a little uncertain.

The moment he rushed into the water curtain before, in his busy schedule, he noticed that there was a rushing underground river in front of the water curtain, sloping down in front of the water curtain, and the drop was estimated to be five or six meters, but he didn't know the rushing river. Where does the underground river lead to?

At this time, Ning Xiaofan observed that the drop behind the water curtain was only three meters high, otherwise, he would have thrown it out of the rubber boat if he could not fix it.

I don't know when this Wangshuitan was formed?The area is only [-] meters square, not big, but it gives people a sense of depth. In this space, even the sound of the water curtain sloping down is much quieter, and it seems relatively quiet.

"Is everyone alright?" Ning Xiaofan asked after calming down.

"It's okay, it's okay, we're all holding on to our seat belts." Hou San and the others responded one after another.

"Old Wang, Xiao Shanzi, did we lose our backpacks?" Ning Xiaofan asked again.

"It's not lost, it's all packed and tied to the rubber raft, even if the raft capsizes, it won't be lost."

After hearing this, Ning Xiaofan felt slightly relieved, and said, "Since everyone is fine and nothing has been lost, let's go ashore first and see if there is a passage."

The pool is not big, just a few paddles away.

When they arrived at the shore, everyone hurriedly dragged the rubber raft ashore. The rubber boat could not be thrown away easily. Lao Wang and Xiao Shanzi began to deflate the rubber boat, Hou San went to explore the way first, and the rest of the people started to take care of it. Pack, organize things.

Everyone was wearing water-repellent clothing. Even if they were soaked in water, except for the surface and exposed hands being stained with water, only droplets of water formed on the clothes on their bodies, which could not be corroded. shake off.

Ning Xiaofan carried his backpack along with him, took out the tablet computer from the backpack to check it, opened the coordinates of the map, and checked the coordinates of where he was, and found that he and the others were not out of the main line. a channel.

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. It has been more than 4 hours since we set off from the base. It should be lunch time now.

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

Lao Wang and Xiao Shanzi are in charge of logistics, which naturally includes cooking.Among the logistics items that the two received this time, most of them were food. As for drinking water, there are underground rivers in the tiankeng. Not only are there many tributaries, but there are also large and small karst caves. .

The groundwater has been tested by early detection personnel, and it is not only non-toxic, but also contains a variety of rich minerals, which belongs to pure natural mineral water.

However, for the sake of caution, Ning Xiaofan ordered Lao Wang and others to test it with an instrument, and still throw a water purification pill when boiling the water to avoid stomach upset after drinking.

Lao Wang and Xiao Shanzi fixed up their lunch, and Ning Xiaofan, Fatty and the others found a flat place to rest as soon as possible, although they didn't consume much energy on the way.

Of course, Ning Xiaofan already knew in his heart that once he entered the tiankeng, his life would no longer be protected by law, and security matters were indispensable, so he arranged for Chen Biao to take up the temporary security task.

After resting for a while, with a burst of aroma wafting into the nose, after a short wait, Pharaoh greeted everyone to eat.
