If you dig up a corpse at the beginning, the system will be awakened directly.

Not long after, the third cave was also cleared directly.

The stone cave in front of them was about [-] meters wide and about the same height. However, for safety reasons, Captain Yan and his team members began to cut the surrounding wood into pieces of wood to reinforce the entrance of the cave.

Having learned the lesson from the last time he dug up anti-Japanese cultural relics, Su Hao did not dare to go directly inside. If someone was accidentally buried, it would be troublesome to dig them out again. Moreover, once they were buried by a huge amount of soil, Whether it would be buried or whether it could survive was a good question. Su Hao felt that there was no need to gamble.

It's not too late to wait for Captain Yan to reinforce the inside before going in. After all, he is a professional and cares about his life, so naturally he will not let a landslide happen.

"The cave has been reinforced, but there will still be extra danger when we enter the cave, because we don't know what will be inside. Su Hao, you follow me, be as careful as possible, and run out if there is anything strange! "

Su Hao nodded, knowing that Captain Yan was thinking about him.

"Captain Yan, you should be careful when exploring the road ahead!" Su Hao also subconsciously replied.

"Just take care of yourself."

Captain Yan took the lead and turned on the flashlight to shine into the cave. This time, no man-made traces were found in the previous two caves. There were rubbles all around, the road looked uneven, and there was nothing carved on the rock wall. It's just an ordinary cave.

Su Hao quickly followed without any hesitation. Because there were many flashlights shining in front of him, Su Hao could see everything in front of him carefully.

The cave in front of you is basically a natural cave, covered with stalagmites, and water droplets continue to condense from the tips of the stalagmites, and then drip to the ground, creating a sound of water dripping.

Because of this, the cave seemed extremely humid. There were small pools forming on the ground. Su Hao had to be careful when stepping over them, for fear that these pools would wet his shoes.

Everyone's eyes kept looking forward. This cave was obviously stranger than the previous two.

The strange thing is these stalagmites and the pools on the ground.

Logically speaking, a karst cave is an underground space formed by karst in soluble rocks.

The formation of caves is the result of long-term dissolution of groundwater in limestone areas. Insoluble calcium carbonate in limestone can be converted into soluble calcium bicarbonate by the action of water and carbon dioxide.

Since each part of the limestone layer contains different amounts of limestone, if the degree of erosion is different, they will gradually be dissolved and divided into independent, steep and beautiful peaks and caves with strange landscapes. The resulting landform will generally be It is called karst landform.

The problem is, generally speaking, there are many caves around the cave, because they are all located on a limestone landscape. But the problem is that except for the cave in front of you, other caves on the mountain will be assimilated into caves, but the other two The cave does not.

Not only Su Hao felt strange, but Captain Yan who was walking in front also felt strange. There should be no such limestone areas that can form caves in Jinghai. Even based on the environment here, there is no dissolved carbon dioxide. Rainwater pours in from the top, forming a cave landscape.

After all, Jinghai is a city with very good air. Not to mention acid rain, smog has never happened. Under such circumstances, such a cave with the nature of a cave appears, and it still exists as a single cave. This makes everyone quite puzzled. I'm confused.

"Stop first, I'll call Director Luo and ask."

Captain Yan was thinking as he walked, and he still couldn't figure out how this natural wonder happened, because it was simply unreasonable. In a landform like a barren mountain, it is absolutely impossible to derive a special natural landform like a cave. Yes, he had read related books after all, but no matter what, he couldn't figure out how this cave appeared here.

"Hey, Lao Yan, what did you find over there? Why did you call me all of a sudden?"

"Luo Guan, we found a cave here, but logically speaking, don't caves always appear in clusters? Why does he appear here alone?"

"What? Cave landform?" Luo Guan was stunned when he heard this. To be honest, he was not sure why there were caves in the barren mountains here.

You know, no cave landforms have been found in the entire Jinghai. This is too strange. The sudden appearance of the cave really surprised them, but they were also a little scared, because the appearance of the cave was so weird. As a result, they were afraid to continue exploring.

"What shall we do now?"

"The remains of human life here have almost been cleaned up. When Xiao Zhao and I come over, you and Xiao Hao will wait at the scene. I am surprised. How can a cave be found here? This is unscientific. ah!"

About ten minutes later, Luo Guan also brought Zhao Guangyi to the third cave. There was no problem at all in leaving the remains of ancient human life in the second cave to the exploration team, although the time did not pass quickly. , but the excitement he felt when he discovered the remains of ancient human life has been replaced by his curiosity about the caves found here. It’s really because he himself doesn’t know why he found the caves here. It’s so strange, even He, the director of the Jinghai City Museum, was also unheard of.

After Director Luo arrived, everyone walked towards the cave while chatting.

"There's something wrong with the humidity. It's much higher than the average humidity in caves."

Curator Luo looked at the temperature displayed by the detection instrument in his hand, and said to the people next to him in confusion. Generally speaking, caves are basically wet, but there is still the possibility of dryness in some cases. .

If the ground has risen and groundwater no longer flows through the cave and blocks the path for water vapor, the area can be relatively dry.

Generally, areas with vigorous karst landforms will have abundant precipitation. Even without the flowing groundwater, the caves may still be wet, but the climate in a certain area may also change, which gives the possibility of drying the caves.

But the problem now is that the cave in front of us has reached an astonishing humidity of more than [-]%. Now the clothes of several people have been soaked by the water mist. Generally speaking, the humidity of the cave will be at [-]%. The humidity range is between [-] and [-], and the selected [-]% humidity is particularly abnormal.

"If the humidity is so high, there is actually a reasonable explanation that can be explained clearly."

At this time, Su Hao suddenly spoke, drawing everyone's attention to him.

"What explanation?" Curator Luo asked immediately. He was a little hopeful and wanted to see if Su Hao's explanation could really convince him. After all, even an old scholar like him in the archeology field couldn't explain the reason. Su Hao What can an excavator know after just one day at the museum?

But at the same time, he actually recognized Su Hao's knowledge. After all, he discovered the ancient city and the bronze tripod first and then deduced the specific age and type of the ancient city, so deep down in his heart, he still believed in Su Hao. Now we are waiting to see whether the conclusion he is about to say is reasonable.

"If you look at this level of humidity, generally speaking, it is possible that the cave leads to an underground river. Once the temperature inside the cave rises, it will cause the humidity inside to rise, causing the humidity to be higher than normal. The cave is much higher, which is why this cave is so humid."

"I see, this seems to be a correct inference. If there is an underground river in this cave, it can prove why the humidity here is higher than that in ordinary caves. Why didn't I think of this at the time?" Luo The curator nodded and agreed with Su Hao's statement.

"It's really because we haven't found any caves here at all, so you subconsciously think that this is a special cave. If it is as Xiaohao inferred, it makes sense why such a cave appears alone here. Yes." Zhao Guangyi listened to Su Hao's words and echoed Director Luo's words.

"Indeed, I never thought that was the case before."

Even Captain Yan agreed with this conclusion. Although he was the captain of the exploration team, he actually graduated from a prestigious university, otherwise he would not be able to hold this position. He wholeheartedly agreed with Su Hao's conclusion just now.

After finding a way to break the situation, they quickly walked towards the inside of the cave. Although it didn't look as big as the second cave from the outside, they found out when they walked inside that it actually led directly to the underground. They walked for hundreds of times in a row. Mi, it’s not the end yet.

Everyone's eyes were on the front, and the audience in the live broadcast room was also infected by the breath of silence. They concentrated on it, and the hand that sent the barrage gradually slowed down at this time.

From ancient times to the present, people have been curious and afraid of unknown things.

The audience has also gathered enough thoughts about this mysterious cave.

In their opinion, although there may not be any treasures found in this cave, they can see the mysterious and beautiful scenery, and they still want to watch this live broadcast.

Everyone in the team showed solemn expressions. They listened attentively to the strange noises coming from around them and did not dare to speak at all.

Even his breathing became subtle, making no obvious sound.

The audience in the live broadcast room was also infected by this atmosphere. Although there are more than a million people watching now, there are only a few barrages. They are all staring at the screen, not daring to be distracted at all, fearing that they will ignore it the next moment. The moment when the favorable evidence proving Su Hao's entire judgment appeared.

Everyone's nervous thoughts came to mind at the moment.

Everyone was calm and followed the team looking into the depths of the cave.

Not long after, a long and thin sound of flowing water appeared in everyone's ears.

Suddenly, everyone's faces were obviously excited.

"The sound of water flowing! It's actually the sound of water flowing!"

I don’t know who shouted first, and then the atmosphere was broken by this sentence.

"Quick, let's move forward!"

Under Director Luo's instructions, everyone also accelerated their pace.

The further you go, the louder the sound of the water becomes.

"This is the sound of an underground river flowing!"

Su Hao couldn't help but speak.

This sentence also moved all the viewers in the live broadcast room, and the barrage quickly appeared in the video screen at this moment.

[Did the host really guess it right? It’s really an underground river, it’s incredible! 】

[Look at the anchor’s expression that doesn’t show any surprise at all. Is this also called a guess? In fact, I feel that the anchor already knew all this, but other people in the museum did not react. A group of museum employees are not as knowledgeable as an excavator anchor. It is really funny to tell people. 】

[That’s not what I said upstairs. Museums are generally only responsible for archeology. Things like geographical addresses are actually not under their control. Moreover, there has never been a cave discovered in Jinghai. They didn’t know it at first. It's normal. Can you express this point of view if you ask me? I don't believe it! 】

[What about the ruins of the ancient Yubi City? Didn’t the anchor say it first? 】

[But Expert Zhao immediately told the history of Yubi City. There is still some real information! 】

[Isn’t that also from Baidu...]

The barrage was about a hot topic. Some people were criticizing the experts in the museum to show Su Hao's knowledge, while the other part were saying this for the experts. In today's online world, there will always be two groups of people who can't be dealt with. There was a quarrel above. Now this kind of environment has penetrated into every network, and Su Hao's live broadcast room is not immune to it.

Soon, a huge underground river appeared in front of everyone.

An underground river system generally includes surface depression and valley subsystems, peak clusters or hilly subsystems and underground pipeline subsystems. The valley subsystem, peak cluster or hilly subsystem accepts the input of material energy from inside and outside the system, such as atmospheric rainfall, snow water, natural loss of land, etc., while the function of the underground pipeline subsystem is to output the material energy within the system, such as constant-temperature groundwater, which can It is said that these are all complementary to the underground river system.

The underground river in front of us is obviously a complex karst underground river composed of underground corridors, caves and dissolution mainly caused by dissolution. In other words, the soil here is looser than other places. Only then could such a large underground river system be formed. In an instant, the scene became extremely grand.

"It's so spectacular. It's more shocking than watching the high tide on the Jinghai River."

"Indeed, Director Luo, look, there are actually fish in the underground river. They are white and quite beautiful."

"Wait a minute, there's something wrong with that fish. Damn it, it's a paddlefish!"
