There should be a huge underground space under this sinkhole, and what we have walked through is only the tip of the iceberg. Just below that mountain, there's sure to be a lot of water-filled space.

This huge scale of collapse is the main cause of the sinkhole. I think this collapse has something to do with the fire I inadvertently caused. I don't know what ingredients are in those animal bones, the temperature of the flame is extremely high, and burning the rock is definitely not a problem. There should be a large amount of water stored in the vicinity of that space, the thickness of the rock wall is different, the heat is uneven, the rock wall is cracked under the combination of cold and heat, and a large amount of cold water is poured into the fire field that has long been turned into a furnace. The hot rock burst with cold, and the roof of the cave lost its support. Even the large amount of carbon monoxide formed by the cold water infusion exploded, causing the collapse.

This is just my conjecture and has no factual basis. But the large amount of dirty water gushing out of the collapse at the bottom of the mountain seemed to confirm my thoughts.

This is the case in nature, where a small event can cause a chain reaction, and the eventual event is often unimaginably large.

I'm not at all inclined to dwell on theories like the butterfly effect, about the other side of the ocean or whatever. But that's exactly what happened.

This time, just because I almost fell down in the ground and fell to the ground with a torch, not only did I ignite a fire that burned the ruins of an unknown number of years ago, and almost burned myself to death, causing a series of dangers in the future, but also causing such a terrible geological disaster, and maybe even further expanding this sinkhole.

It occurred to me that the formation of this sinkhole was not so simple, and that there was a strange distinction between life and death, and that there were also human activities at work.

The collapse was still widening, and the splendid picture scroll was gradually burned to ashes, and the python also noticed what was happening down the mountain after a few swallows. Without looking at us too much, we turned into a black light along the mountain and disappeared.

I quipped, "See, people are looking for a place to watch the show!" ”

Liu Dongwu was distracted and ignored me.

I was bored and rested on the side, when suddenly there was a commotion in the mountains, and countless unknown small animals were running towards the mountains. These things don't usually know where they live, and only then do they take refuge in high places. These gadgets are fluffy, bring their families with them, and are cute. It was interesting for me to watch, and the pain in my body seemed to be much better.

At this time, I suddenly heard Liu Dongxi's roar, "Run!" ”

I snapped awake and ran? Where to run?

At this time, we had already come out of the hole in the tree and sat on the trunk of the tree, and Liu Shixi grabbed me and was about to jump under the tree.

I saw that this is not fatal, the diameter of this tree is less than three meters, such a height is usually not a problem to jump, but at this time the physical strength has been exhausted, and I am still being dragged by people to passively fall, isn't this iron-hearted to kill me?

I grabbed Liu, "What are you running?" What's wrong? ”

"The mountain is falling!"

In the rumbling sound that was getting closer and closer, I heard Liu Dongxi's words clearly! The mountain is about to collapse?

Sure enough, the collapse had spread to the foot of the mountain, and I could clearly see large chunks of ground with vegetation falling into hundreds of thousands of kilometers of hollows, and then sinking into the water at an unknown depth, causing a spectacular splash. The mountain that was originally thought to be indestructible is also irrevocably bursting!

Run! But where are you going?

I saw a giant tree that had grown at the foot of the mountain for an unknown number of years shaking and falling down, and when it fell into the abyss, it looked like a cauliflower that was spinning and falling against the background.

In the distance, an adjacent hill burst open from the middle, scattering and falling with a loud noise, and soon disappeared into the great mouth of the earth's crust.

The mountain under his feet is even shaking, trembling, and **, and it seems that it will soon be torn apart and sink into the ground. I have no doubt that it will sink into the ground after the explosion, just like the hill next to it.

In this case, where to run?

Liu Dongxi saw the apocalyptic scene in front of him, and obviously thought about it clearly, standing at the end of the broken tree with a pale face, looking at the bottom of the mountain and silent!

I think he looks like this with the energy to find death!

"Don't pretend to be cool when you're dying!"

Liu didn't look back, "Don't speak, I want to be quiet before I die!" ”

When I saw that this thing behaved very differently than usual, this kind of pessimistic words should not be what he would say, and I don't know how to say it if I want to persuade him. Surviving in a disaster of this level is simply an impossible task, and the thought that I will never be able to go out again makes my heart feel sad for a while.

Just when I was worried about it, Liu Dongxi turned around and said, "It's too chaotic here, let's go into the tree hole to rest!" ”

I was stunned for a moment when I heard him say this, but when I thought about it, I understood what he meant.

This place is expected to be a body of water eventually, and the roots of those trees are buried deep in the ground, and it may be difficult to float for a while, but our tree has broken off, like a naturally formed canoe, and it will definitely float on the water after everything has calmed down. And in the imminent collapse, there will be chaos around us, and the fragile human body will be difficult to survive in the collision and friction of these hard and large objects, and the protection of this tree will undoubtedly greatly improve the chances of survival for both of us.

We climbed into the hollow of the tree with jagged gaps.

The tree is broken off from the edge of the tree hole on the first floor, and the partition between the two layers is half a meter thick, which is very strong. There are two openings in the top, both about the middle. There are some fine tears in the surrounding wood, but they are not breathable, except for the irregular shape, it is simply a small cabin.

We looked around inside, and there was nothing like a grip, and God knows what the tree was doing to make its belly so flat.

I simply made a few grooves in it, and I could barely hold it in place by kicking it against the wall. Liu Dongxi concocted according to the law and sat on my left side.

In this way, the two of us sat in this tree hollow, silently counting the roar and vibration outside, like two astronauts sitting in the space shuttle, waiting for the moment of departure.

At this point, I suddenly realized that something was wrong, and that we seemed to be putting ourselves in an even more dangerous situation!

We've all studied physics and know that when an object is falling, air resistance determines the speed and posture of the fall. The object with the same volume and density is fast, and the same object, the denser one is facing down. When the mountain we are in falls, the whole mountain must fall the fastest, and then the tree will break away from the mountain, like a parachute, and the canopy will fall up into the whirlpool below.

I don't know how much force the trunk has into the water, but when you enter the water from this angle, the whole hole is like an engine cylinder, and the water pouring in is like a piston squeezing in. Then there are only two endings, the first is that we are squeezed by the sudden increase in pressure, and the second is that the tree hole cannot withstand this pressure and is squeezed.

Either way, we're all going to die!

Of course, I don't know if there is enough distance to complete this positional transition during this fall, but in any case, the tree hole below is not safe.

I quickly got up and kicked Liu Shi, "Get up, climb out with me." ”

Liu was inexplicable, "You're crazy, what are you doing out?" Look for death! ”

"Hurry up, I'll explain to you when I get out!"

Liu Shixi seemed to think that I was nervous, and leaned against the wall to ignore me.

By this time, the sound of vibration had reached the feet! That roar seems to be ringing in my ears! The whole tree began to tremble unnormally, and the ground was about to sink!
