Due to geological drilling on the surface, the vibration of the sedimentary rock produced a strong shock wave, which was transmitted to the egg cave in the earth's crust, causing the roof of the cave to collapse.
Song, Yi, and Jin were forced to retreat to the reverse gravity egg cave. The risks were unknown and their progress was blocked.
"I don't know how this group of people got the detonators and medicine. It's definitely not legal for them to do this." Chen Mingzhi said.
Zhao Xixi couldn't help but sigh, "Yes, what a beautiful starry sky, they destroyed it. Such geological wonders are unparalleled in the world."
Song Yijin and Jiang Xiaobao walked to the entrance of the cave to observe Zhao Xixi reminded them to pay attention to safety.
The shock wave transmitted from above is expanding to the surroundings, causing a wider range of metamorphic rock formations to break and collapse, but the intensity is gradually weakening.
The ground is covered with pieces of faulted stone pages, shining brightly.
After the cave roof fell off, the sky was still filled with stars, which was extremely beautiful.
After peeling off a layer of rock, there is still gold inside. This is also in line with Zhao Xixi's prediction of the thickness of the rock layer at the top of the cave.
At this time, Zhao Xixi also came over and looked at everything helplessly, "If the top of this egg cave is an oval clam shell, with the sky pillar, the shock wave can be transmitted to the ground. Without it, The Tianzhu is equivalent to hitting a hammer on tempered glass. Even if the force is not strong, a small shock wave is enough to shatter the entire cave roof.
As the shock wave spreads around, the scope of rock fragmentation continues to expand, and the rocks are broken. The crackling sound continued, crisp and messy.
Before Zhao Xixi could finish speaking, there were deafening bursts of thunder and roar, accompanied by countless landslides and rain of rocks, and the entire cave roof was briefly covered with turtles. After it cracked, it suddenly fell off.
A huge sound swept the sky full of gravel and rock dust and rushed towards the entrance of the cave, pushing Song Yijin and the four of them back more than ten meters.
Wait. After they climbed up with difficulty, their eardrums were buzzing and they couldn't stop.
Then they hit the rocks at the bottom of the cave, causing a huge second earthquake wave, and the cave shook for a while. It was thrilling and indescribable.
Song Yijin quickly pulled Zhao Xixi and the three of them back and continued to retreat. The three of them were still in shock after they had retreated more than 500 meters.
The four of them were still in shock. Dust, with his head down and his legs up, sat on the stone without even noticing that he turned over due to the gravity here.
Song Yijin handed over the towel. To Zhao Xixi, unexpectedly, Zhao Xixi burst into laughter.
Jiang Xiaobao and Chen Mingzhi were frightened, "This girl was scared to death, wasn't she? "
Only Song Yijin knew this, and the two looked at each other and laughed without saying a word.
Zhao Xixi has been crying and laughing recently. There are too many things in her heart, but facing Song Yijin I can still understand her in her eyes.
Despite the collapse of such a large geological rock formation, the dragon's chant comes on time every half hour. It is like the piano of the earth's crust, the bells in the morning and the drums in the evening, never absent.
"What should I do? The whole top has fallen off. Is it still okay?" Jiang Xiaobao asked. There was a big swelling on his forehead, probably from being hit by the gravel that rushed in just now.
"It's definitely impossible to get through here. It's difficult to walk. The bottom of the cave is full of rocks. The big ones are several meters thick, and the small ones are thirty or forty centimeters. They are arranged horizontally and vertically." Zhao Xixi shook her head and said.
"With the peeling off of this layer of rock, the inner layer has also become loose. Drilling a little deeper into the sedimentary rock will trigger a larger collapse."
"The earth is also fragile. Why can't it withstand such a small drill! How thick is the drill bit?" Chen Mingzhi seemed unable to understand.
"The rock formation in an egg cave collapsed, just like you pinched a mark on your leg with your fingernails. The earth is still the earth, it doesn't affect anything. Isn't it the same every time you hear the dragon's roar? It will be passed on in an hour."
"Let's take a nap first, get some rest, and wait for the dust over there to calm down before we take a look. There will always be an exit," Song Yijin suggested.
Jiang Xiaobao was worried, "Would the collapse of that one affect this place?"
"No, just keep it in your stomach. The gravity here is different. That's not the same rock formation," Zhao Xixi said.
The speaker has no intention, but the listener has the intention.
"You said this place is not in the same rock formation as the starry sky?"
"Why?"
"Ah, you stopped me in my tracks."
"I understand. This reverse gravity is not a complete crustal rock layer, but an underground river that has formed a huge overhead plate between two fault cliffs and valleys after hundreds of millions of years of flow. " Zhao Xixi said.
"No wonder, this place is full of cobblestones, and the gravity will be misaligned! Maybe after a certain period of time, the two fault plates will shift, and this place will be squeezed like a twist." Jiang Xiaobao said.
"Wow, listening to you is better than studying for ten years! You two great professors are extremely talented and knowledgeable. You are so powerful!"
Song Yijin was thoughtful, he I feel like there must be some connection. Maybe finding this answer will help us find our way out.
Zhao Xixi and the other three fell asleep leaning on the stones, but Song Yijin couldn't fall asleep.
He looked at the cobblestones on the ground, trying to find some clues from this up and down space.
At this time, the dragon roar sounded again, and the sound seemed clearer and louder than before.
Song Yijin's heart moved, and he decided to go to the starry sky to check it out.
He stood up quietly, trying not to wake the others, and walked towards the starry sky at the entrance of the cave.
At this time, the dust in the starry sky has settled, but the aura is in chaos, and the original beautiful top of the starry sky has been eclipsed.
Song Yijin carefully observed the surrounding environment. He found that the metamorphic rocks containing gold ore that fell here seemed different from other places, with strange textures and lights.
He looked up from time to time to prevent any more stones from falling. He noticed that in addition to many golden palm-sized objects on these boulders, there were some strange symbols that seemed to be naturally formed.
These golden things should be gold mines.
Song Yijin had no time to study these, he needed to quickly find a way out.
The entire bottom of the cave is now full of messy stones, with no place to stay. It is too difficult to walk on it.
Song Yijin had no choice but to climb up to the entrance of the cave and find another way.
Suddenly, he vaguely felt two low-amplitude vibrations, followed by a strong negative pressure from inside the cave entrance, sucking him inside. But there was no wind.
He didn’t know the reason. Could it be the distortion of reverse suction?
At this time, the low-amplitude vibration had stopped. He followed the suction and walked inside to see if Zhao Xixi and the others were awake.
As soon as he stepped in, even when he was about to fall over, he felt something strange under his feet.
Not good! The bottom of the cave is sinking.
——The elevated plate between the two faults that Zhao Xixi mentioned is sinking as a whole!
Song Yijin suddenly remembered.
At this time, he was crawling and rolling towards Zhao Xixi and the three of them, and loudly woke them up, "Get up and follow me, this place has collapsed!"
"What? Collapsed?" Jiang Xiaobao asked in disbelief.
"Isn't this good? Where did it collapse?"
"Stop talking nonsense! If you want to live, run with me!" Song Yijin ordered, holding Zhao Xixi's hand as he spoke , running desperately towards the cave entrance.
The earthquake amplitude began to intensify, and the bottom of the cave was sinking at a scale visible to the naked eye.
This chapter is not finished yet, click on the next page to continue reading.
At this time, the gap between the bottom of the cave and the entrance had reached more than one meter. Song Yijin quickly jumped up to the entrance and dragged Zhao Xixi up. But the terrible thing is that Jiang Xiaobao and Chen Mingzhi are still down there. If they don't come up, they will fall into the endless abyss.
Zhao Xixi cried anxiously and shouted their two names, while Song Yijin held Zhao Xixi's hand tightly.
When Jiang Xiaobao and Chen Mingzhi ran to the entrance of the cave, the drop had reached three meters, and the bottom of the cave continued to sink, and the speed was accelerating.
"Sit tight and don't move!" Song Yijin was so anxious that he pushed Zhao Xixi back three or four steps and then jumped down.
"Quick! Climb onto my shoulders! Climb up! Xiaobao, help him! Hurry!" He pulled Chen Mingzhi over, he raised his hands and lay on the cave wall.
"Xiaobao, you go up first."
"Stop talking nonsense, get up quickly!" Jiang Xiaobao pushed Chen Mingzhi up, and Chen Mingzhi put his hands on the hole and successfully climbed up. Climbed up.
Then Jiang Xiaobao climbed onto Song Yijin's shoulders as if desperately trying, and Chen Mingzhi dragged him up.
It’s too risky! Jiang Xiaobao's hand almost didn't reach the entrance of the hole.
But the two of them went up, but Song Yijin did not.
Zhao Xixi was anxious. The bottom of the cave would be like a wild horse, sliding down to the mantle abyss hundreds of thousands of meters below. She hurriedly ran to the entrance of the cave and shouted: "Big cousin, big cousin, where are you?"
"I can't go up, it's going to be fatal. The bottom of the cave is sinking and there is no foothold!" Song Yijin responded below.
"Don't you know kung fu? Why don't you jump up?" Zhao Xixi stuck her head down, looking for Song Yijin.
"The bottom is unstable, there is no footing, and I can't exert any strength."
"Don't go any further, be careful of falling." Jiang Xiaobao from behind also reminded Zhao Xixi anxiously.
However, Zhao Xixi couldn't care about anything at this time. Her voice became hoarse because of worry and anxiety. She leaned forward again, hoping to see more clearly. Unexpectedly, her legs trembled and she fell down. Gotta go down.
Jiang Xiaobao and Chen Mingzhi screamed in fright!
Zhao Xixi was scared out of her wits, but she felt like she was caught by a pair of particularly strong arms, and a special manly earthy breath was sprayed on her face.
"Silly girl, why did you jump down?" Song Yijin looked at her with a smile and winked at her.
It seems that both of them have forgotten that they are sliding into the bottomless abyss.
Song Yijin stood on a piece of stone, kicked hard with both feet, and supported Zhao Xixi slowly up to the hole above and then back down.
Looking down at this time, there was no shadow at the bottom of the cave, and only bursts of dark wind were swishing upwards accompanied by a vibrating sound.
"Where is this hole going to fall to?" Song Yijin asked mischievously.
"Bottomless abyss, eternal eternity!" She didn't like such a joke at all.
The four people were finally out of danger. Jiang Xiaobao asked Song Yijin how he knew the bottom of the cave was sinking.
Song Yijin recounted what happened when he was looking for a way out of the cave.
"It's so dangerous. If my eldest cousin hadn't gone out and fell asleep with us, all four of us would have slipped to the center of the earth."
But at this time How to get out again has become a huge problem. There is a bottomless abyss on one side and a cluster of rocks on the other. It has become an unsolvable problem.
The four of them leaned against the cave wall. The entrance of the cave was only less than twenty meters deep and four meters wide.
Chen Mingzhi said, “Either we walk out of the rocks., you can go out after walking to the end. ”
“There is no way to walk here. There is no place to set foot. Not to mention people, animals can’t walk.” "Jiang Xiaobao objected.
"It's really difficult to walk. I can only walk for a few minutes. It's too difficult to go out on this road. And I’m not sure if any more rocks will fall from it. "Zhao Xixi also said the same.
"What should I do? You can't just stay at the entrance of this cave, right? "
"Don't worry, there is always a way. "
Song Yijin stood up and walked towards the starry sky again to look down. Jiang Xiaobao was also looking around the entrance of the cave, hoping to find something different.
Suddenly, Jiang Xiaobao seemed to have discovered something unusual.
He was repeatedly tapping a spot on the cave wall with his fist, and the sound was dull and hollow. Song Yijin's eyes lit up, and he ran over and knocked a few times, and then knocked on other places.
“It’s empty in here! "Song Yijin said.
"Knock it open? "
"No, what if it causes geological problems again? "Zhao Xixi objected. She was worried that breaking the cave wall would cause problems at the entrance, and then they would have no place to stay.
But after thinking about it, she thought she could give it a try.
"You guys find a stone and try knocking it a few times. If you can knock it too hard, make a small hole first and then expand it. "
Chen Mingzhi immediately found a stone and gently hit it against the cave wall. Unexpectedly, after just one hit, a one-meter-wide hole was made with a clang, and it turned out to be a cave!

Zhao Xixi hurried over to take a look. She was puzzled as to how a cave could appear here, and it was natural, with no trace of artificial excavation.
The cave was endless. Extended, the height is seven or eight meters, and the width varies. It is basically two or three meters wide. The bottom of the cave is relatively flat.
Song Yijin grabbed both sides of the cave entrance with his hands and shouted inside: "Zhao——Xi." --hope! "
There was no echo in the cave.
"This is a living cave. It may have passed all the way along the wall of the starry cave outside. " Zhao Xixi speculated.
"Then let's go from here. If it doesn't work, we can walk back at worst. "Chen Mingzhi said.
"Jiang Xiaobao, you have merit. "Chen Mingzhi said and gave Jiang Xiaobao a thumbs up to praise him.
Jiang Xiaobao wiped his hair with his right hand and shook his head back to express acceptance.
"Don't be in a hurry. , it’s better to wait for half an hour before going in. Because the cave entrance here is closed and has only been opened now, some toxic gases may have accumulated inside over the years. In addition to containing large amounts of oxygen, carbon dioxide and hydrogen, the pores or cracks of rocks, rock formations, and rock shale also contain toxic hydrogen sulfide. , methane and other gases, so it’s better to hold off for now. Now that the hole has been opened, what's insideThe draft can completely change the air in half an hour. " Zhao Xixi said.
At this time, the four people's faces turned from sadness to joy, looking at the gold ore on the ground under the starry sky. Jiang Xiaobao joked again, "Chen Mingzhi, why don't we jointly open a mining company? , what’s the idea of you being the chairman and mining these gold mines and refining them into gold nuggets? "
Chen Mingzhi's eyes gleamed with gold, and he said with great joy, "What a great idea. With so many gold mines, how much gold will be refined? This is to become the richest man. Hahaha! ”
“Why should he be the chairman of the board? Zhao Xixi can’t!” "Song Yijin said boredly.
"Whoever invests more will be the winner. "Chen Mingzhi took it seriously.
He walked over, slowly descended to the starry sky, carefully looked at a golden rock, dug it with his fingernails, and then lay down and bit it with his teeth, seriously.
The three people here looked at his funny look and laughed non-stop.
The wind inside the cave was blown out, mixed with a cold and turbid air. The smell.
No one knows whether they will get out safely after entering this cave, or whether they will have another thrilling experience.
