Water mist into a mirror!

All of this weirdness comes from the mist in the air. It is the same principle as the appearance of a mirage on the surface of the sea, the refraction of light and shadow. Refraction and total reflection occur when the air temperature changes abnormally vertically, and the humidity in the air reaches a certain proportion.

There is a way out of the mirage, which is an illusory world created entirely by the refraction of light, and generally appears under white light. But it was completely dark, and the only source of light was my flashlight, and the beam spread out, and it would be swallowed up by the darkness. Therefore, the point of that exit must be real, and it must have been illuminated by my light, which was refracted and changed the original path.

It is still the human eye that deceives itself into thinking that what it sees is a straight line, when in fact it is likely to be a sinuous line, and the exit to be found is somewhere in this broken line. The difficulty in this part is that I can't judge how far the flashlight starts to refract, and in which way it is refracted? I'm not an expert in mathematical reasoning, and I can't judge by the naked eye, so I can only choose to use the dumbest method.

I placed the flashlight on the ground and let the light remain, but I closed my eyes to avoid the impact, starting from the light source and measuring the human body, and climbed around the rectangular curve from the left. Each time, half a body position is used as a benchmark, and the range of this human body measurement is gradually expanded. As long as my deduction is correct, the exit is hidden in a corner of the light, then there must be a sand wall and a hard object.

He wasn't stupid one after another, and he must have thought of everything I could think of, so it's likely that he had already found the exit first.

When I counted to the second horizontal line of the ninth lap, the emperor lived up to his wishes, and I finally touched a hard object, and when I touched it, it felt as wet as the top wall. Walking along the wall, after only two minutes of climbing, my hand touched a vacancy, and when I opened my eyes, I saw that the light was shining here, which was the exit point that I had been entangled for a long time, but I saw that the halo was very weak, which was dispersed by the mist.

It was a small hole, large enough for people to pass through, and before I could get out, I heard a familiar and wary ask, "Who?" ”

As soon as my heart is relieved, it is one after another. I hurriedly responded, and immediately a light came from outside the hole, and then the breath approached, and my hand was caught, "Xiao Jiu, how can you find this?" "Can I say it took a lot of effort?

I was helped to carefully get out of the hole, and when I stood still, I realized that there was a lot of space here, and people no longer had to bend down or crawl. I asked him about the situation first, and he only came out of the hole a few minutes before me, and he was also wandering in the mezzanine, and he couldn't find the exit for a long time. As for the way to find an exit in the end, I felt embarrassed after he said it, why didn't I think of it?

After discovering the refraction of the water mist, he used a sharp knife to pierce some small stones on the ground, and then really borrowed the trick of "throwing stones to ask for directions", judging from the time and sound of the stones rolling under the same force, he quickly found out the direction where he hit the wall earlier.

He said that he knew that I must be anxious, but he could not shout loudly to warn me from inside, for fear that if there were wild animals in the mezzanine or outside the hole, it would cause trouble. This idea is tacitly in line with me.

Now that he and I have come out of the mezzanine space, he doesn't need to find a way to go back to me, so he took the backpack that had been hooked in the crook of my arm and asked, "Where's your flashlight?" Lost inside? ”

After he mentioned this, I suddenly remembered that there was another person in it, and when I asked about it, he didn't know anything, it seemed that his route was different from mine, and he didn't meet that person. At this time, I also noticed that when I looked inside the cave from the outside of the cave, I couldn't see any points of light, so it was no wonder that I was standing outside the cave one after another, not knowing what was going on inside me.

After asking me about the man's age and appearance, he decided to climb back and take the man out of the mezzanine. I don't have an opinion, the other party still has a breath of air, if you can save it, it's better to save it, and maybe you can get some information from this person.

The way to rescue him was to think of one after another, because the point where the person was clear only to me and could go back, and let me go back the same way, and tie a long line between the two of us, which was in the bag. In this way, when I return to the original point, I only need to pull the rope and drive the climb over one after another, saving the complicated process in the middle. After listening to the stupid solution I found, the corners of his mouth twitched, and he even felt a hidden smile in his eyes, and I thought sullenly: Laughing can't kill you.

Crawling back to the original point, I first picked up a flashlight on the ground and took a picture of the man's face, which was still the same as before, still unconscious. Then I will be pulled over one after another, but after seeing the man's face, I am keenly aware that the complexion of the man has changed abruptly. Do they know?

Without explaining on the spot, he passed the person through his armpit with a rope and tied it to his leg. In such a small space, to move a faint unconscious person, it can only be dragged in this way. He turned around and ordered: "Xiao Jiu, you push his feet forward from behind, and I will lead the way in front." ”

He leads the way? Realizing something, he shone a flashlight at his location, and immediately discovered the clue. It turned out that when he came in, he tied another rope to the entrance of the cave, so there was no need to use my "stupid method" on the return trip at this time.

When a puzzle is solved, it seems that what was once complex becomes simple. Soon we dragged the man out of the mezzanine, and when I got off the ground, I saw that he was pressing the man's mouth and giving first aid, and after a while I asked, "Do you know him?" ”

Seeing that his expression was suffocated, he paused for two or three seconds before nodding his head and saying, "He is Dongdong's new husband Yu Qiuyuan." ”

This answer was really unexpected to me, and I could meet it if I drilled a hole...... Acquaintance? This probability is not ordinary, even if you don't have a brain, you can roughly understand what's going on. It seems that he was hit by a blind cat and a dead mouse, and he hit it right, and this place is exactly the destination he is looking for.

In fact, after reading the text on the metal plate and taking a cursory look at the map, I realized that the map drawn by his father back then was mainly a map of the inside of the cave, and it was also the route he had walked, and as for the outside of the cave, it was simply depicted a few lines. After more than ten years of wind and frost, the landform may have changed, and it is difficult to identify the route of those simple lines, and it is no wonder that it is difficult to find it when driving one after another, and only the approximate range can be known.

The question comes back to the present, Dongdong's husband Yu Qiuyuan appeared here, does it mean that she is also there? Then I recalled a story that I was told one after another in Heizhugou, he said that Dongdong's father, Han Jiancheng, went on a mission arranged by his superiors half a year ago, and he has not returned, and his family listened through various connections and learned that the name of this mission was 'Operation Death Valley', so Dongdong began to search for information about Death Valley. She didn't go to Heizhugou, and she saw her in Golmud a month ago, apparently targeting it.

It seems that there is still something to hide from me, he chased him to Golmud, what information did he get from Dongdong, and where did she go later. The former question is not easy to answer, but the latter is already clear, and here she is.

It is estimated that my face was different and was seen one after another, he sighed lightly and said: "Xiao Jiu, don't look at me like that, there are some things that I don't want to hide from you, but I don't know how to speak." In addition, Yu Qiuyuan has always been with her, and at the same time in Golmud, there are several colleagues of Han Jiancheng, which Yu Qiuyuan is considered his student. At that time, I found your photo from the forum, and I searched around like crazy, and by the time I reacted, they had already left Golmud, and after a little inquiry, I knew that they were heading for the Kunlun Pass. Later, I found that under the pillow in my room, there was a photo of a dead tree in the poplar forest, and I knew that it was a hint left by Dongdong, but I really didn't have the heart to pay attention to it at that time. ”

He turned his gaze awkwardly, and then stared at me with blazing eyes at the end, which was self-evident, saying that his mind was focused on finding my whereabouts at that time. I have to admit that after listening to his explanation, I felt a lot more comfortable.

After a moment of silence, he spoke his analysis: "That means that they came here first, but I don't think they came down from the hole where we came down, if there were several people, then it would be impossible for them to come all the way through the hole without any traces." So the only explanation is that they got here from another way, and assuming that Dongdong had seen the parchment map in the bottle before she gave you the picture to remind you to go to the poplar forest to find the map, and if you follow the old route, you should have the same problem as us, and you can't find the right location. Is it possible that they have a more detailed map of the cave entrance? ”

"Not impossible." After muttering one after another, he replied, "With Han Jiancheng's deep thoughts, the possibility of drawing his own map is very high, and in the past ten years, it is impossible for him to be silent and put this place aside, and pay attention to this situation at all times." ”

What he didn't say was that Dongdong was Han Jiancheng's daughter, and since she was able to eliminate the possibility of Heizhugou Death Valley and came here directly, it meant that she must have learned something from it. No, I always feel that something is missing in the middle, which is very important.

First of all, let's sort out the time, more than a month ago, when I was in Heizhugou, I said that Han Jiancheng had not returned for half a year to participate in the Death Valley mission, and then Dongdong had a quarrel with him two months before the trip to Heizhugou, and then left. At that time, it was only four months before Han Jiancheng left the mission. On the surface, Dongdong walked away in a bad mood, but in fact, he married Yu Qiuyuan in front of him, just imagine that the two of them get married, can he not attend as a father?

So I boldly assumed: "Is it possible that Han Jiancheng actually came out, otherwise they would be able to get married if he didn't return and his family was worried?" His mouth moved one after another, and he stopped talking, and he said after a while: "They didn't have a wedding, so they got the certificate." ”

After a little thought, I understood what he meant, "You want to say that Dongdong married him impulsively because of negative energy?" But seeing his embarrassed face, his eyes dodged and he didn't dare to look at me, "Xiao Jiu, that's all in the past, don't dig my old bottom before." ”

After a glance, Yun said lightly: "If the foundation is innocent, why should you be afraid of being dug up?" ”

He was choked for a moment, his face alternating black and white.
