Look at the stupid look on my face. Lin Yiru had no choice but to briefly explain to me what a dammed lake is. I would also like to emphasize here that the dammed lake may be familiar to those children today, and the Internet, television, mobile phones, these convenient props are very simple to bring people closer.

What is happening in one place can be known almost immediately in another place far away in the sky. The speed at which information is transmitted and spread is completely unimaginable at the time. So today's children are very knowledgeable, and nothing can surprise them. I have to lament that I am behind the times.

In our time, it was the perfect embodiment of the so-called interlaced like a mountain, everyone only knew what they should know, professional, purposeful, except for meteorology, I can say that even today's middle school students are inferior, naturally it is impossible to know the geological term of dammed lake.

The so-called dammed lake refers to the landslide, debris flow or lava blocking the river valley or riverbed, and the lake formed when the water is stored to a certain extent, usually caused by natural causes such as earthquakes, wind disasters, volcanic eruptions, etc., and there are also dammed lakes created by human factors, such as ** fire, engineering excavation, etc.

When the dammed lake structure is scoured, eroded, dissolved, collapsed, etc., the dammed lake will appear "overflow", and eventually because the dammed lake structure is in extremely poor geological conditions, the evolution of "embankment" and the flash flood will occur instantly, which will have devastating damage to the downstream areas.

Lakes formed by the interception of volcanic lava flows are also known as lava dam lakes. Lin Yiru emphasized this definition.

"So what's going on?" I don't know why. "What does this have to do with our canyon? Although it is true that there are a lot of volcanic rocks there. ”

Lin Yiru behaved even more helplessly, as if she was like playing the piano to a cow. I'm still not angry at all, but I think it's funny with her expression, and she's showing it more and more lately. I don't know why, I just love to see her embarrassed or helpless expression. So a lot of the time, I deliberately caused her to show that expression. There may be a lot of people who will call me bad-hearted, but in those days, there were very few ways for us to express our feelings.

I knew I couldn't just go and confess stupidly, that's what kids do now. It's not a question of whether we have the courage or not, but we don't have the concept of confession at all, and the only way to express our emotions is to cultivate revolutionary feelings together. We don't allow the so-called love at first sight, it's the only thing that can be accepted.

So my progress with gravity is very slow, even if we have lost everything and are wanted by the whole country, some deep-rooted ideologies are not so simple to change. And now I'm very satisfied with this relationship, I don't want to get closer, if the feeling of separation is good, casual actions will narrow the distance between each other, it is definitely not worth the loss.

I believe that feelings are cultivated slowly, even if Lin Yiru doesn't have any special thoughts about me now, but from the time I desperately rescued her from the mouth of the giant python, we can't be regarded as a simple meeting. Gradually, she showed me some of the feelings that a human being should have, and that's a good thing, everything has to be done slowly.

And most importantly, until I get Chen Jae-hai and Talia out, everything will be on the back burner. Now that's the main purpose of my life, I can't imagine what my life would be like without them at all, and if they did die, I wasn't sure I wouldn't go with them. The emotions of birth and death are not so easy to let go.

Even if Lin Yiru confessed to me on the spot, I think I would refuse, because I don't have the qualifications yet. I've always thought that I was a bastard when I watched the two of them go away. I should have followed them, and I should have even pulled them down! And I let them both go so unconsciously and unconsciously

I resented, I lamented, I was heartbroken, and when I knew that the two of them were completely lost in that nothingness, a strong, like a flood of beast self-reproach, completely swallowed me up. Get them out no matter what! This is my only thought, it makes me not hesitate to point a gun at Lin Yiru and threaten, but also to achieve it.

I have always been grateful to Lin Yiru. She was the one who saved me from that mess. It was also she who agreed to my joining the most, and agreed to save Chen Zaihai and Talia. As far as the result is concerned, her proposal to let me go away at that time was the most correct, and in the end, I realized who was the person who put himself in my shoes from beginning to end

"Doesn't it seem like your brain is made of elm?" She said.

"Is it obvious? It's a canyon anyway, and there's no water," I said.

She spread her hair back on, her movements becoming a little anxious, and suddenly she stared at me with a little stubbornness. It seems that I just pressed some strange switch on her, and she doesn't seem to let me understand and swears not to give up, and I always think that she is a little scary like this.

"That's not what I meant! Use your own mind to think about where you ended up and what the canyon floor looked like. Her voice became fast.

I? I ended up falling into a huge underground river, and the canyon itself was made of a lot of volcanic rock, and the point was full of sand. This means:

Thinking back to her explanation of the dammed lake, I suddenly felt that I knew what was going on. In a sense, that canyon was a dammed lake! According to Lin Yiru, after the formation of a dammed lake, the dam will eventually burst as the water continues to accumulate, causing great damage to the downstream areas, and the higher the altitude of the river, the greater the harm. Depending on the situation, it is possible to form a kind of 'hanging lake' of the most dangerous kind. This is a special kind of dammed lake at high altitude, due to a strong earthquake, a large number of rockfalls or landslides block the gap between the two mountains, forming a large hanging pit, and the water in the nearby river will accumulate in this large pit. Once these fallings are no longer sustainable, they will eventually be mixed with a large amount of water and devastating the lower elevations below the mountain.

"You mean that a dammed lake similar to a 'hanging lake' has also formed in the ground of that unknown depth?" I asked tentatively.

She nodded approvingly, saying yes, the truth should be the same. The place where you fell is not a canyon at all, but a large dammed lake formed by some volcanic activity! The area is originally volcano-prone area, so you must know that you have been bathed in hot springs, right? This kind of geological phenomenon can also be formed when magma is cooled, and unlike ordinary rocks, volcanic rocks are brittle because they do not contain much sulfur and have a loose structure, so they cannot withstand high pressures.

If the ground was normal, eighty percent of the water that had accumulated would have collapsed the canyon.

"But we were underground, weren't we?" I feel like everything makes sense.

"It seems that you are not useless yet. Yes, you are really underground, and all the water in that place is groundwater, and the flow of groundwater is closely related to the rainfall on the ground and the distribution of rivers. So the water level of the groundwater is very unstable, and you learned about it in that volcanic tunnel before, right? That sudden rise in water almost flooded the entire tunnel, right? She explained. The best explanation is the underground river you fell into, the water level that should have been silted up on it went down, and the dammed lake dried up. Those eight achievements of sand are left behind by the rising water and falling into the water again and again. ”

After listening to her explanation, I only had one thought. Who would have thought that in a place that does not know how deep underground, there would be a kind of 'hanging lake' that can only be found at high altitudes. But on second thought, it's not that unthinkable, especially compared to the things we've encountered later.

"So it's a matter of those two trains that we're going to fall?" I asked.

Lin Yiru said that this is the case, when you fell down for the first time, you had smashed those loose volcanic rocks even more loosely, and after the second column fell, people with a little common sense would move away from that place. It's better for you to take the initiative to stick to it, and if you don't fall, whoever falls.

And weren't there other photos at that time? Show us and we might be able to find something else. After hearing her question, I suddenly remembered that I hadn't had time to put away those photos at that time! Those things must have sunk to the bottom of the river with the train now

"It's really not enough to succeed and more to lose, Brother Su, the things you cared about so much at the time didn't have time to put them up in the end." Yukiri, who had been quietly listening to our discussion, finally gloated and sneered.

This time she said that there was no problem at all, this was indeed my negligence, at that time I was blinded, patronizing and fleeing for my life, except for the one that was casually sandwiched in the labor insurance notebook before, everything else was put in place

"Forget it, it's useless to complain about him at this time. None of us have personally experienced that kind of thing, and anyone will stand and talk without backache. Lin Yiru started a round for me after this time.

For a moment I thought I had misheard, that she would say such a thing for me? On the other side is her favorite sister! Looking at her expressionless face as always, I don't know why, but I feel that she is warmer than ever.

It seems that people change, whether it's me or her
