"It's rare that the vents aren't backfilled, so don't follow too tightly when you get in." After saying goodbye to me, the old prostitute turned on the flashlight, put the backpack on her chest, and then climbed in first.

I saw the old prostitute climb five meters away, so I followed her inside. This is for the sake of safety, I always keep a distance of five meters from him, and if the old prostitute encounters any unexpected situation in front of him, he still has room to retreat.

While following the old prostitute forward, I observed the situation around me. It was a ramp down the ventilation duct, and the space inside was much larger than a normal thief hole, but it was not enough to walk in it, and we had to crawl on our knees. There are rocks from the top to the bottom, left and right, but they seem to have been carefully polished, and there are no edges or corners.

At first, the old prostitute climbed very fast in front, but after a few tens of meters, the old prostitute's speed began to slow down. I was holding a flashlight in the back, and most of the light was on his legs and buttocks, and I couldn't see what was going on in front of me at all, so I didn't know what was going on in front of me.

I asked the old prostitute softly, "Is there any situation ahead?"

"Nope"

"Then why did you suddenly slow down?" I asked.

"That's where I came in before, there's no danger, and I don't know anything further." The old prostitute continued: "Have you noticed that the slope here is bigger than the one just now?" ”

"Your big ass is in the way, it's almost blocking the ventilation duct, I can find something, I can't see the situation in front of me at all."

"Oh my god, or you're in front."

After saying "hurry up", I quickly crawled over, slapped the old prostitute's ass with a flashlight, and shouted "drive" again.

"Fuck, what the fuck are you driving donkeys?" The old prostitute scolded in front.

"You'd like to be a donkey, but you're never as big as a donkey."

"Fuck you." After scolding the old prostitute, he began to speed up.

Indeed, in the next few tens of meters of climbing, I also felt that this section of the slope became much larger.

After crawling forward for a few more minutes, the old prostitute suddenly stopped, and then said, "Xiao Qi, do you feel the wind here?" ”

As soon as I heard the old prostitute say that there was wind, I immediately became alert and stretched out a hand to sense where the wind came from.

After a few seconds, I did feel a gust of wind, but it wasn't strong, it was blowing from the outside to the inside. I looked back and saw nothing unusual in the back.

"The wind is blowing in through the mouth of the cave." I said.

"I knew the wind was coming from the hole, but it wasn't blowing in." I turned my head and looked back at the front, and the old prostitute happened to look back and back, and we looked at each other, and the old prostitute continued, "This wind is kind of like being sucked in." ”

"Sucked in?" When I heard this, I was a little different, and I couldn't help but ask, "How could it be sucked in?" ”

"If the wind blows in, we should feel it when we are at the entrance of the cave, and we shouldn't find it here."

I nodded, thinking that there was some truth in what the old prostitute said. Of course, there is also a possibility that there is no wind outside when we come in, so there is no wind in the ventilation duct, but after a long time, it may be windy outside. If it's windy outside, it's normal for the wind to blow in.

I exchanged my thoughts with the old prostitute, who thought for a few seconds, shook her head, and said, "No, even if there is a strong wind outside, it may not be able to blow in." Don't forget, there is a copper coffin at the entrance of the cave, and no amount of wind can easily blow in. ”

"If the wind is sucked in according to your analysis, then there should be a suction fan at the end of this ventilation channel." I wondered.

"Oh my god, there is no power facility here, how can there be a suction fan."

"And how do you think the wind gets in?"

The old prostitute shook her head and said, "No matter what causes this wind, we have to be careful." ”

After saying that, the old prostitute continued to crawl forward, but this time the speed was slower. In fact, this may be a psychological effect, just like queuing, the one in the back is always too slow in front, and it is in the case that I can't see the front, so I always feel that the old prostitute climbs too slowly.

Time was consuming minute by minute, and after another dozen minutes, we were still crawling on our knees in the ventilation tunnel, which was so uncomfortable that I was already sweating. It's not that we feel that tired, we don't actually crawl very far, but it's just that it's a little unbearable to keep a position, especially the knees and arms, which feel very sore.

"Old prostitute, you estimate how far we are before we can get to the end." I asked.

The old prostitute looked back at me, but he didn't stop his hands and feet, and continued to crawl forward, saying, "I don't know, if you're tired, let's rest for a while." ”

I saw that the old prostitute's face was also full of sweat, and I guess I was tired, I just said to take a break, and before I finished speaking, I saw the old prostitute leaning, as if a hand was empty, and the whole person instantly tilted, and then slid forward.

I immediately tried to pull his leg forward, but we were a little far away, and as soon as I touched his leg, before I could grasp it, he had already slid down the air duct.

It was then that I could see that the ventilation duct ahead was no longer a slow slope, but had become extremely steep, and that there was a parallel fork in the road.

At the moment when I saw the front clearly, my upper body was already in the steep ventilation channel, and it was too late to say that it was too fast, without waiting for me to react, and without even having time to scream, I just slid down with the old prostitute.

It was different from previous falls, surrounded by hard stones, and although the stones were polished to the point of absence of edges and corners, I instinctively protected my head.

I don't know how fast I'm descending at the moment, but I guess it's not slower than a water slide.

This kind of slippage and high-altitude fall are indeed too different, high-altitude fall is only a momentary thing, and it may have landed before you have time to be afraid, even if you are nervous, it will be transformed into the pain of landing in an instant. But this kind of slipping and falling was really nerve-wracking, and after more than ten seconds, I was still slipping rapidly in the ventilation tunnel, and I couldn't predict when I would stop.

Just as I was trying to calm my heartbeat, there was a broken voice from below, and the screams of an old prostitute. Immediately after, I felt myself out of the ventilation duct and no stone around me.

But before I could feel what was around me, a shattering sound and a pain in my body came almost at the same time. I don't know if I hit something, but I felt a huge pain in my lower back, and then the position of the fall changed. But this change only happened for a moment, and then it changed again, and I felt my body slap on the ground, and I didn't know what I had hit on my head, and I felt dizzy.

A distinct feature appeared before my eyes, and countless stars began to revolve around me.

I don't know how many seconds I was dizzy, but it was definitely not a minute, the time was very short, and I heard the old prostitute shouting: "Get up quickly, if you don't get up, I will be crushed to death by you." ”

I staggered up, but I couldn't stand at all, and sat down again, but instead of sitting on the old prostitute, I sat in the water.

I touched it with my hand and the water wasn't deep, so it didn't go through the vamp. But the water wasn't the ground, it was wood, which made me a little curious.

The first thought in my heart at that time was, did I fall into the coffin? After a few more strokes of my hand in the water, I dispelled this thought. Because what I touched was not a whole plank, the wood underneath was spliced, and it was certainly not a coffin board.

In order to be able to observe the situation around me as soon as possible, I kept rubbing my head with my hands to return myself to a normal state.

During this time, I heard many voices, all from the old prostitute, sometimes the sound of water, sometimes the sound of wood, as if he had not been idle since he stood up, as if he was moving something.

As my vision became clearer, I realized that it was a wooden room, but most of the wood had rotted away, and it looked like it was in tatters. There was a big hole less than five meters away from me, and the old prostitute was standing there looking out.

I looked up and saw that it was also made of wood, and there was a large hole directly above me. This big hole looks like it has just formed, and it should have been smashed out by me and the old prostitute.

Looking up the hole, I couldn't help but feel a little scared, and at a height of about thirty meters, I saw a ventilation tunnel on the top of the stone, and I didn't have to think about it to guess where we fell.

I had to gasp at the sight of the vents above. Thirty meters of falling space, fortunately this is falling into the wood, if this is smashed on the ground, then the old prostitute and I will not directly accompany the Yama Dou landlord.

I was suddenly very grateful for the wood on my head, fortunately there was these wood to block it, otherwise it would have fallen directly into the layer of wood below, and the result of me and the old prostitute would have been quite miserable.

"How are you, old lady? You okay. I asked, turning my head.

After all, I fell on him when I fell, so I think he should have hurt more than I did.

When I turned my head around, I found that the old prostitute was gone, and I was left alone in the whole wooden room.

I knew this guy must have gone out of that big hole, and immediately stood up and wanted to go over and have a look. But I don't know if I don't stand up, and as soon as I stand up, I find that my waist injury is not light, and it hurts very much. I gritted my teeth and insisted on standing up, and when I walked to the big hole, I saw that there was a lot of space outside, and the old prostitute had walked out more than ten meters away.

The old prostitute was looking after me with a flashlight, which surprised me. Although the position he looked after was in my direction, it was not from here, but above me.

"What are you looking at?" I asked the old prostitute.

"It's a ship"

"Boat?" I looked up and saw nothing but the plank overhead.

"Come out and see," said the old prostitute.

I walked to the old prostitute's position, looked back, and was shocked, it was really an ancient ship.
