The distance between the two rock walls is only about twenty meters, and the middle is full of sand. The train we were riding was stuck in the sand in an inverted V-shape. This is supposed to be a crack left behind by some kind of large geological activity, and given the situation here, it is likely to be volcanic activity.

Chen Zaihai said that this one should have been formed for many reasons, and that a long time ago it should have been just a gap for lava to flow, perhaps only a few meters wide. After the magma disappeared, the outside underwent a series of water-dissolved erosion and cascading collapses to form that huge underground space.

Then this tiny crack was eroded by the wind, day after day, year after year, until it became the canyon we are in now.

"Look at this height, it's impossible for us to climb up again, what should we do?" Chen Zaihai raised the torch upwards and said.

"Since you can't go up, you can only go flat. If there is a sandstorm of this magnitude, it means that there must be a huge wind. Talia speculated.

This sentence makes a lot of sense, at least let's be sure that we won't be trapped in this canyon. We jumped off the scrapped train and walked down the sand. From this point of view, I realized how violent the previous impact was, because the fire was buried in the sand, and I can't tell what it was. But the various parts and unknown devices scattered around me made me know how lucky I was.

As soon as we came down, we felt that the wind had become lighter and the sound of the wind in our ears was nothing more than something that had been enlarged by the canyon, and there was nothing to care about. What worries me is the whining sound, which seems to be becoming more and more obvious, still every ten seconds, and the regularity is so regular that it makes people numb.

"Do you feel that this voice is closer to us?" I said with some trepidation.

If this strange sound was something I had never heard before, it was fine, I could force myself to ignore it and run away. It's just that this thing is very familiar to me, as if it is like an old friend who has not seen each other for a long time, and I can't remember anything, but I only know that I know each other.

This made me unconsciously pay attention to the sound, and after a while I was distraught, and I really wanted to climb up and see what it was.

"Indeed, no matter how you listen to it, I feel that Lao Tzu has heard it there and made Lao Tzu uneasy." Chan is in Kaido. "We don't have the money to wait for it now, so let's run away quickly. If something happens to the ancestor of the godsend, we will really be finished. ”

After Chen Zaihai finished speaking, he took the lead towards the end of the canyon, and as I walked, I realized that it was not all sand. There are still many places that are not buried, and you can clearly see the dark rocky ground. Talia took out a sapper shovel and smashed a small piece down to study as a sample.

Along the way, we rarely saw any other kind of rock except volcanic rock, and the appearance of this black rock here seemed to make Talia very concerned. Although we were in a hurry, we could afford to wait for a stone.

"This should be basalt, Chen Zaihai, you can see if it is." Talia then looked at the miner's lamp for a while, and then handed it to Chen Zaihai, who was leading the way in front.

"That's right, and it looks like it's obviously hundreds of millions of years old, not on the same level as these hundreds of years of volcanic rock." He looked at it a few times and judged.

"So this space has existed for a long time, and volcanic activity has only started in the last few hundred years?" I asked.

"Yes, such examples are rare, but not uncommon." Talia replied. "We don't study geology, and we can't infer anything complicated."

I only now know how big the gap between these amateurs and Lin Yiru is, when I was looking at those strange volcanic rocks in the forest, she seemed to have expected that there would be such a huge space underground.

I don't know if I'll ever see her again in my lifetime, but we don't have much time to spend together. But for some reason, since the last time she visited me, who was injured trying to save her, I had developed a strange feeling for her. I can't tell if it's a good impression or not, but I feel like I'm attracted to some of her qualities

"But even if we know this, it won't help our situation at all. It's time to go, it's still going to go. "Chen Zaihai returned the basalt to Talia and asked her to keep it as a sample." Also, Lao Su put away your spring dream-like expression, it looks so disgusting. ”

"Indeed, Su Zhenpeng, your saliva is going to flow out." Talia deliberately kept me away.

Yes? Do I have such an expression? I immediately touched the corners of my mouth, and I didn't feel any wetness at all. These two guys are definitely there for me to have fun. I just thought about Lin Yiru just now

"Haha, are you really going to confirm? Chen Zaihai was right. Talia laughed relaxedly. So which sweetheart do you think of? ”

She bypassed the engineer on the side and walked in front of Chen Zaihai, put her hands on Chen Zaihai's shoulders, and poked her head out of Chen Zaihai's shoulders. There was a playful light in his eyes, and Chen Zaihai also looked back at me with a wicked smile.

"Who else could it be. Do you think that Lao Su was injured last time to save - who was injured? "He deliberately stretched the word save very long.

I felt like my liad was about to burn up, and I started to walk unsteadily. A few times I almost walked to the top of the sand, how long did these two guys want to play with me?

"Ahh It can't be me, right? Su Zhenpeng saved me in the train before, I really thank you. But when it comes to that kind of concern, I'm still a little bit," Talia said, looking surprised and a little shy. And she seems to have misunderstood something

"I've always treated you as a family member and a brother. So whether it's telling you about your past before, or hugging you and comforting you, it's all the feelings between family members. Don't think about it! Talia was trying to explain something, and although it looked a little cute, I always felt very pathetic about myself now

Why should I be rejected so completely by someone who doesn't feel it at all? And more than once! What did I do, I really shouldn't have thought of Lin Yiru just now.

"Then I said Talia, you should have misunderstood Lao Su. I said that he was in his hand, and it was the python who made it," Chen Zaihai patted Taria's hand on his shoulder helplessly.

After hearing him say this, I noticed that Talia's whole body was visibly stiff, and her steps stopped all of a sudden. But Chen Zaihai was still moving forward, and the two of them had an accident as soon as they walked and stopped. Chen Zaihai himself has a lot of strength, and he is much higher than Talya, and Talya was immediately brought forward by him, and the balance between the two people disappeared all of a sudden. I could only watch as the two of them collapsed in a cloud of sand, splashing a lot of dust.

The pile of sand was so loose that it couldn't hold the weight of the two of them. was smashed out of the big pit of the two of them in the shape of two people in an instant, and Chen Zaihai and the others were deeply trapped.

What the hell are these two people up to? I still remember Chen Zaihai saying that there was something wrong with the sand, but I couldn't let them stay in it for too long. I immediately tried to dig them out with the engineers.

"Bah, what the hell, Talia, why didn't you leave all of a sudden?" As soon as he was dug out, Chen Zaihai began to spit out the sand in his mouth constantly.

"You still talk about me! I knew I had misunderstood, so you didn't stop me in a hurry. I'm so embarrassed! "Talia also looks disgraced.

"You said it so fast, did you give me a chance to interject!" Chen Zaihai was helped up by the engineer and immediately complained.

"Is that the reason? What can't you do if you want to stop me! "Talia really didn't accept him for this reason at all.

Looking at the two of them, I once again confirmed that they were the real bunch of happy enemies. I was immediately amused, and the irritability that had been accumulating in my heart disappeared all at once. How could the two of them deliberately reject me, I was so stupid before.

"Ahh I remember! The time you said that Su Zhenpeng was injured was indeed for a woman! It was so chaotic that I didn't see it clearly, so who was that? After the new journey, Talia asked Chen Zaihai.

"Ahh You say she? I'll tell you when you come here, it's interesting, I never thought there could be such a coincidence. That guy was from the geology team" and then she started biting Talya's ear, and I couldn't hear it at all.

I just felt that Talia's tightness changed from confusion to surprise, from surprise to laughter. What the hell did that guy say to Talia? I kept asking after that, and the two of them just laughed and didn't say anything

The answer to this question was only obtained on the night when Lin Yiru and I were on the train, and I was really confused at that time.

After a bit of laughter, I realized that I hadn't really gone far. In the distance, you can still see the dark shadows of our two trains, and it is probably less than a hundred meters away. This is also helpless, this place is too difficult to walk, the sand pile is all like the one that Chen Zaihai and they fell into just now, stepping on a pit, and they can't walk at all. We can only move along the easier gaps in the middle of the sandpile, and there is no difference between the twists and the maze in which they are distributed.

What's worse is that some places are not completely stony, and the sand surface will be paved with a layer of deadly sand, so that if you step on it, you will fall into it completely, and it is very difficult to pull it out again. We've actually walked almost a kilometer, but it's still not far from the train.

The voice above his head approached, and the ease of laughing just now gradually disappeared. We were getting a little nervous, and my sense of immediacy was even worse, the sound was so familiar! We immediately quickened our pace, for everyone realized that it would not be long before the owner of the sound would most likely fall from above!

At first we walked briskly, but as the oppression above our heads grew, we began to run desperately, and the thing was about to come
