I stared at the smoke hovering overhead, thought for a while, and said, "The wind in the cave should be similar to the 'passing wind', from a low mouth to a high mouth, and if there is no wind above our heads, there is no hole entrance, and the knowledge of physics should not deceive people." ”

The fat man also looked at the smoke that was rolling into the darkness, and then looked at the location of the willow eyebrow mark on the cave wall, and said, "Waste, if this is not the entrance of the cave when we came, what is the matter with the mark of the little willow painting." ”

"This ......"

The fat man looked at me speechlessly, looked at Liu Rumei and asked with a smile: "Xiao Liu, are you a traitor?" ”

"Huh......"

Although Liu Rumei knew that the fat man was joking, she didn't know how to answer him, and reluctantly squeezed out a smile. Just when I was worried that she would feel embarrassed, she said, "This must have been the mark I made, and it must have been the first mark I made when I first entered the hole, and I think the crack when I came in must still be here, but we ignored something." ”

"What ...... overlooked"

The four fell silent, each pondering details that might have been overlooked. The fat man looked at the smoke that gradually dissipated, put out the half of the cigarette in his hand on the ground, and then said: "Don't think about it, it's trapped now, and it's a waste of time to think about the details. ”

Wen Xianbao took out a marker pen from his backpack, made a mark on the wall next to him, and said, "Wang Bo is right, this is not a way, we have to act." ”

I frowned and looked at the mark that Wen Xianbao had just drawn on the cave wall, which was a red Arabic numeral '1'.

"This is just a regular marker." He looked at me staring at the mark, explained it to me, and then smiled and said to Liu Rumei: "Rumei, let's walk together in a while, and use two pens to make marks at the same time, so that we can see the marks whether there is light or not." ”

Liu Rumei didn't say anything, just nodded silently.

Wen Xianbao put his backpack back on his back, and then said, "If you have any opinions, let's take action." ”

Liu Rumei: "Hmm." ”

Fat man: "I think it's better to be careful, first identify the direction before leaving." ”

We were on a road, and although we couldn't find the entrance to the cave for some reason, there was no fork in the hole. I didn't understand what the fat man said, and asked, "How can I recognize this?" ”

My question drew the fat man from the look of an idiot. Liu Rumei, who was on the side, took out a box from her backpack, shook it in front of me, and then said to me, "Compass." ”

The compass is an uncommon tool, but it is an absolute must-have tool for field workers. Liu Rumei first glanced at the trend of the cave, then used the compass to determine the direction, then took out a notebook and made a careful note on it, and after doing all this, he said to us: "Okay, let's go." ”

The four of us walked deeper into the cave again, and unlike before, this time neither of us had the heart to gossip. Liu Rumei kept taking notes in the stop-and-go. The fat man copied the sapper shovel and knocked on the cave wall "clanging" along the way. Wen Xianbao and I looked around as we walked, stopping and observing carefully everywhere we went, for fear of missing any details.

The fat man suddenly stopped and asked, "Waste, are we going uphill or downhill this way?" ”

I've actually noticed this problem, but the cave has no obvious ups and downs, and I don't think it's going uphill or downhill along the way. So, I shook my head at the fat man, saying that I didn't know either.

Liu Rumei heard our conversation, she also stopped, looked through the notebook, and then asked the fat man seriously: "Wang Bo, can you light a cigarette?" ”

"Huh?" The fat man was stunned for a moment, then grinned and said, "I'm ordered to smoke." ”

As he spoke, the fat man quickly took out a cigarette from his pocket and held it to his mouth, lit it and inhaled sharply, and then slowly exhaled the smoke. The smoke swirled in one direction under the light of the flashlight, and that was the direction the four of us were heading.

Liu Rumei looked at the smoke that gradually drifted away, and looked carefully at it in his notebook for a while, and then said: "This cave has some twists and turns, but the general direction is still to the southwest, from the turn back to the present, we have walked a total of more than 13,000 steps, about ten kilometers. ”

"There's something wrong with that." After listening to her words, I frowned and said, "We entered the cave from the top of the mountain, and walked two kilometers uphill in one direction, shouldn't we have gone out a long time ago?" ”

Liu Rumei lowered her head and wrote and drew in her notebook, her eyebrows twisted. Wen Xianbao looked at her quietly from the side, as if he was also thinking about something. The fat man looked at them, turned around and walked over and asked in a low voice, "Waste, do you think we should go back?" ”

"Go back?" I repeated the fat man's words, thought for a moment, and said, "What if I go back and be in the same situation as before?" ”

What I said, the fat man must have thought of it too, he frowned and took a deep puff of his cigarette.

I saw that he didn't speak, and then said: "Xiaoyanagi has been looking at the compass, we have walked roughly in one direction for ten kilometers, how big is this mountain, don't you have a score in your heart?" ”

"I don't think the current situation can be explained by common sense, and there are strange things everywhere." As he spoke, the fat man took another deep puff of his cigarette, and walked back and forth with his head down, and the mottled flashlight flickered as he walked. However, at this time, the unexpected suddenly happened.

"Oops......"

The fat man exclaimed, as if he had stepped on the air, and his huge body suddenly fell into the darkness. Before I could even react to what was happening, I heard the sound of gravel sliding in my ears, and the dust flying in front of me filled the hole, and I hurriedly covered my mouth and nose with my collar so that I didn't choke on the dust.

I didn't have a flashlight in my hand, and I couldn't see the light of the fat man's flashlight, so I hurriedly waved the dust in front of me with my hand and shouted at the front: "Fatty, fat...... Ahem......"

"Hey...... Phew......" The fat man's voice came, and he seemed to be spitting out something, probably dust in his mouth.

"How's it going, fat man?" I asked in the direction of his voice, but there was still a lot of dust around me, and I couldn't see him. At this time, Liu Rumei and Wen Xianbao also came over, and they used the strong flashlight in their hands to shine forward, but the dust in the cave was very large, the visibility was very low, and the fat man was still not seen.

"Not dead yet...... Phew......" The fat man continued to spit and said, "I rub, where did I fall?" ”

Liu Rumei followed the fat man's voice, illuminated the ground with a strong flashlight, and carefully moved a few steps forward, as she walked, the sound of gravel sliding down came again, I hurriedly pulled her with my hand, signaling her not to go further.

At this time, the fat man's voice came again, and he said angrily, "Bah...... I rub it, why do you still drop stones? This is to bury your fat man alive...... Phew......"

At this time, although there is still a lot of dust, it is much less than just now, and the surrounding situation can gradually be seen. Only then did I see that there was a hole in the ground, which was not very large, about a meter in diameter, and the voice of the fat man came from below.

With the light of the strong flashlight, Liu Rumei and I looked down cautiously, and the dust was so thick that we could vaguely see the situation below. Below it looks like a cave with a big bottom and a small mouth, about four or five meters deep, and you can see a pile of rubble under the collapse at the bottom of the cave, and the fat man is sitting on this pile of rubble.

"Fatty, what's wrong, didn't you fall wrong?" I asked eagerly.

"I can't die." The fat man answered, looking up. At this time, I saw that his appearance was indeed a little miserable, and the whole person became a native person, no wonder he kept spitting in that area, and it was estimated that there was a lot of sand and gravel in his mouth during the collapse.

"You try to move, see if you hurt your bones, if you can move yourself, we'll pull you up." After Liu Rumei handed me the flashlight, while shouting to the fat man, she untied her backpack and began to rummage, and soon she took out a ball of rope from it, and a few quick hangings, and then she quickly arranged the ropes.

"Hmm." The fat man agreed, then slowly moved his hands and feet, and finally slowly stood up from the pile of rubble at the bottom of the cave. He tried to stretch his waist again, twisting back and forth twice, probably thinking that he was fine, so he shouted upward: "I don't have any big problems, but my butt hurts a little." ”

"It's okay." I listened to him say it was okay, and I was relieved.

The fat man groped in the rubble pile with his head down for a long time, and finally found the bright flashlight he dropped, which was probably extinguished when he fell. The fat man wiped the dust from it with his hands, then reopened, holding a flashlight to the cave he had fallen into.

I watched the fat man's every move from above, and was sure that he was really okay, so I took my eyes back. Liu Rumei had already packed up the rope at this time, tied one end to her waist, and threw the other end into the hole after hanging it quickly. At this time, Wen Xianbao also walked over, grabbed the rope, hung a quick hanger on it, and tied it around his waist. I also followed their example, and hung a quick hook around my waist, and after tying the rope, I looked at the fat man at the bottom of the cave again.

The fat man did not rush to pick up the rope at this time, but held a strong flashlight to the side, and stretched his neck to look around, as if he had seen something strange. The dust in the cave had dispersed, but it was still a little difficult to see far away, and I didn't know what the fat man was looking at, so I shouted to him: "Fat man, don't look at it, quickly tie the rope and we will pull you up." ”

“……”

As a result, the fat man did not respond at all, so I looked sideways and looked down, and I couldn't help but be stunned, because I found that the fat man was no longer underneath. Just when I was wondering, the fat man's voice came from below: "Rub ...... It's an egg. ”

"What?" Liu Rumei and I both crawled at the entrance of the cave, and when we heard the fat man's voice, we couldn't help but ask in unison.

"Eggs." When the fat man heard us ask him, he was probably afraid that we would not understand, so he said again: "Eggs, eggs of eggs." ”
