Rebirth system is starting

Guning County, which is 400 kilometers away from City C in Province Y, is a remote and isolated place located in a mountainous area.But here is surrounded by mountains, beautiful scenery.Such a poor and backward mountainous area suddenly attracted the attention of the whole world in the middle of this century.

In the middle of a mountain with an altitude of only more than 500 meters within the scope of Guning County, there is a huge stone pit.This stone pit is very large, the area of ​​the pit mouth alone is the size of 5 football fields.The depth is unknown, but at least a few hundred meters.Geologists call it a tiankeng.

In the field of geology, the huge stone pits that appear in karst areas are called tiankengs.There are many reasons why sinkholes appear.There are even human factors.Once there was a farmer who suddenly heard a loud bang when he was working in the field, and a huge pit appeared on the ground.This is due to people's excessive exploitation of groundwater, resulting in land subsidence.Strictly speaking, this is not a sinkhole.

How did the tiankeng in Guning County form?Some people say it was caused by an earthquake, some say there is an alien base at the bottom of the crater, and some say it is a crater.But the locals said that there used to be monsters here.

As a mountaineering enthusiast and an adventure lover, Xu Chuan was fortunate to participate in that investigation project.It stands to reason that an amateur scientific expedition team member like him cannot participate in such a professional scientific expedition project.But because he met a professional scientific expedition team member during an expedition, the other party was very optimistic about his physical and mental quality, so he recommended him to the leader of the scientific expedition team at that time.

This expedition team is composed of scientific expedition members from China, Britain and the United States.The leader of the team was a Chinese geography professor named Zhu.Professor Zhu led the expedition team of less than 20 people to Guning County.

Along the way, they discovered the distinctive features of Guning County.The ancient limestone is widely distributed in the Guning area, which should belong to the typical karst landform.Unlike other karst geological distribution areas, which are usually desolate and barren, soil erosion is serious.The Guning area is a scene of lush greenery and lush vegetation.

What kind of tiankeng will be hidden in the mountains less than a few hundred meters?All the scientific expedition team members including Xu Chuan had such a question in their hearts.

However, when they really arrived at the Tiankeng, everyone was deeply shocked by the scene there.

Through the thick fog, everyone can see the huge tiankeng is bottomless.The rocks on the four walls are steep and upright.The rocks of the tiankeng look black, and there are few plants on the cliffs.Under the shroud of mist, it seems to be as mysterious as some giant beast is hidden.Standing outside the mountain, I never imagined that there is such a big tiankeng in such a short mountain.

There is a village of about a hundred households around the tiankeng.People in the village don't call Tiankeng "tiankeng", but Shenkeng.They are in awe of the tiankeng.And they said that the weather can be forecast by means of fog at the mouth of the pit.At the same time, they also firmly believe that there is a guardian beast called "Xiansheng" guarding the tiankeng.This kind of beast has the ability to predict the death of people.

Professor Zhu roughly estimated the depth with an instrument, and it was estimated to be no less than 500 meters.Because the pit walls are so steep, the only way to get accurate data is to descend vertically to the bottom.

The expedition team did not rush down to the pit immediately, but observed the terrain of the entire tiankeng.Xu Chuan found a gap in the eastern part of the tiankeng, and immediately informed Professor Zhu.Professor Zhu led the scientific expedition team to visit the local villagers. The villagers told him that there is a

The cave they called Zhongdong.

After deliberation, the inspection team decided to start from the gap, go down to the middle hole first, and then go down to the bottom of the hole.This can greatly reduce various risks.

However, directly descending vertically to the bottom of the pit with a rope is a very dangerous behavior.Because no one knows whether there are really monsters at the bottom of the pit, and whether the fog at the bottom of the pit is poisonous.Xu Chuan volunteered to express his willingness to go down to the bottom of the pit first.

Since he didn't have much experience, Professor Zhu rejected his proposal, but chose an experienced scientific expedition team member to take the lead and go down with him.

After checking all the devices on their bodies, the two slowly walked towards the bottom of the pit.After nearly two hours, Xu Chuan and the expedition team member named Zhou Ming arrived at the middle cave.Xu Chuan wiped the sweat off his neck. Although he was not exhausted, he was still a little tired.He thought that if it weren't for the middle hole, they would have been exhausted before they reached the bottom.

It was already noon when we really reached the bottom of the pit.Fortunately, the sun dispelled the fog at this time, making the scenery at the bottom of the pit more clearly visible.Both Xu Chuan and Zhou Ming looked at the scenery at the bottom of the pit with amazement.

They seem to have arrived in a primeval forest.There are lush trees everywhere, which are completely different from the vegetation outside the pit.Shrouded in a slight mist, the bottom of the bushy pit is like a fairyland in the underground palace.

Xu Chuan and Zhou Ming roughly patrolled around the bottom of the pit, but they didn't find the monster that the villagers were talking about.After proving that there was no danger at the bottom of the pit, the scientific expedition team arrived at the bottom of the pit one after another.They found that the rocks at the bottom and mouth of the pit belonged to contemporaneous limestone and showed no signs of melting.You must know that if it is a crater formed by a meteorite hitting the ground, the high temperature on the surface of the meteorite will cause the rock to melt and change.But judging from the rocks at the bottom of the pit, there is no such sign.Instead, a large amount of rubble was found, which experts believe may be related to the earthquake.

So is the tiankeng formed by an earthquake?Experts from the three countries discussed it and agreed that the evidence is insufficient and further investigation is needed.

At this moment, a team member suddenly exclaimed.

"I see... I saw a white animal passing by." Sun Nan, who was the one who exclaimed just now, said.

"What?" The other team members didn't believe that it was the mythical beast that the villagers said, maybe it was an animal that lived at the bottom of the pit!

"It's not your eyesight, is it? How can there be large animals at the bottom of such a pit?" a team member joked.

"I'm not mistaken," Sun Nan glared at him, and said, "That animal has white fur all over its body, it's big, bigger than me, and it just disappeared over there."

Sun Nan is about 1.8 meters tall, bigger than it, probably almost two meters.If it is true, then the size of this animal is really not small.

It can't really be the mythical beast called "Born"!

When Xu Chuan and Zhou Ming heard what Sunan said, they looked at each other with suspicion.

The area of ​​the bottom of the pit is not as big as the mouth of the pit, which is about 3 football fields!Although blocked by these vegetation, the two of them walked around here before the other scientific expedition team members came down.But no white animals were found.Did you see them hiding on purpose?

Xu Chuan looked in the direction where the white animal pointed out by Sun Nan disappeared. It was covered by layers of bushes, so it was not clear what was abnormal.

Xu Chuan thought for a while, but still couldn't suppress the curiosity in his heart, he pushed aside the bushes and walked over there.As soon as he got up, he was held down by Zhou Ming.

"Don't act on your own," Zhou Ming said.

Xu Chuan turned around and glanced at Zhou Ming and said, "I'm just a little curious."

"Curiosity killed the cat. We are here to investigate the terrain, not to explore." Zhou Ming also looked in the direction Xu Chuan was walking just now, and said, "But maybe we should really go and have a look."

Zhou Ming patted Xu Chuan on the shoulder and turned to look for Professor Zhu.

"Captain Zhu, I think Sun Nan may have read it wrong just now." Zhou Ming said: "The bottom of this pit is so big. Xu Chuan and I have checked it once. If there is such a big animal, it is impossible not to find it. And let it The giant animal may have been hiding in a cave or something, we just haven't found it."

Professor Zhu considered it for a while and said, "I'll discuss it with others."

Professor Zhu discussed with the team members from the other two countries.

The captain of the British scientific expedition team said: "I suspect that the formation here may not only be caused by earthquakes, but also by underground rivers. I found traces of water erosion on the rocks over there. If the cave can be found, it may be Can discover underground rivers."

After discussing for a while, everyone explored in the direction Sun Nan pointed out.Soon they found a hole more than a person's height in a place half covered by trees.

At this time, someone found a footprint at the entrance of the cave.An old team member with very rich field experience carefully observed the footprints and said, "Looking at the footprints, I can't tell what kind of creature it is, but the size should not be small."

Looking in from the entrance of the cave, it was dark.The members of the scientific expedition team are not timid, and the equipment is also very complete, so they walked in together.

After crossing a relatively narrow section, the cave gradually widened, allowing at least two people to pass side by side.Due to the erosion of underground rivers, many caves of different sizes appear in the cave.

"There is the sound of water!" The team members with sharp ears have heard the rushing sound of the water in front of them.

Sure enough, an underground river was found in front.This dark river is not wide, just like a small stream.Continuing along the creek, they finally discovered a large underground river.The current of this river is very fast, and several rivers like the stream just now converged into this dark river.There is a flat area around the dark river, which is quite large.

I looked at the time, it was already night.Professor Zhu decided to set up camp in the cave at night.Take out some of the food you carry with you, and share it with everyone.After hours of continuous work, everyone is a bit tired.Because Xu Chuan was young and in good physical condition, he didn't feel too tired yet.

He took a bright flashlight and looked around.A strange plant was found beneath the rock face.

This kind of plant is only about five centimeters high. The leaves are jagged, and a hard stem sticks out from the middle. The calyx in the center of the hard stem drags a flower that is not much bigger than a grain of rice.

Xu Chuan turned off the flashlight and found that the flower was emitting a faint light.The light is very faint, and it is almost impossible to find it if you don't look carefully.There were about a dozen of these plants around. Xu Chuan took a collection bag from the team members, carefully dug up one plant, put it into the collection bag with a part of the soil, and put it into the collection box.

There is almost no light in the cave, so everyone keeps watch by hand.After a night's rest, Professor Zhu decided to continue walking along the dark river.

The author has something to say: I have something to do today, and it will be a little later.The little fish is getting tired...

There is still class in the evening, so I won't say anything...
