With a flashlight in my left hand and a pistol in my right, I didn't dare to be careless for a moment. Follow the light of the flashlight all the way up.

The original structure of this hole is funnel-shaped, wide at the top and narrow at the bottom. I tried to shine the flashlight in the middle, but it didn't hit. I can't help it, I can only try to go up.

Gradually, there was no road in the sky. I looked up at the stone wall above, and it was very strangely designed, there were many small holes chiseled into it, and I didn't know what it was for. At this time, Zhang Yu shouted at me, "Qin Xiaoke, how is it?"

When the voice came to me, it was very weak, but I could hear it, and I tried to use all my strength and shouted at Zhang Yu, "It's almost good, it's very likely that the mechanism exists on this."

The words echoed throughout the cave for a long time, and I myself was startled by myself, and at the same time, a fine sweat overflowed from my forehead, which completely exposed my position.

I glanced to the side, didn't notice anything unusual, breathed a sigh of relief, and hurriedly shot around with a flashlight.

At this time, I was surprised to find that the shape of the cave was not what I had imagined. He is thick in the middle and narrow below and above. The light of the flashlight shone straight onto a boulder suspended in the air in the middle.

The boulder is square in shape and dark gray in color. There were a lot of stone holes in it, and several iron locks were pierced through it, and the whole boulder fell up.

On each side of the boulder are long black hemp ropes. And there is a main wheel (similar to the pulley we used to physically obtain) in the sky, which is rigidly fastened above, and the other wheels are scattered around, interspersed with black hemp rope.

I excitedly shouted to the bottom, "I found the mechanism." Upon closer inspection, I was amazed to see a pull tab on top of the boulder.

Just when I was happy, I suddenly felt someone pushing behind me, I hurriedly flashed to the side, although most of the force was removed, but the center of gravity was still shifted, and the whole person fell downward. In desperation, I lost the pistol, and grabbed the hemp rope on the side with my big hand. Immediately, I tied the flashlight to my waist with my other hand, and moved my hands up and down in unison, and I couldn't go up on the road, so I hurried towards the stone platform hanging in the air.

The pain of two hands was painful, I gritted my teeth secretly, fortunately I had practiced martial arts since I was a child, and my body was considered light, and I suddenly jumped onto the stone surface. Just when I was still hesitating, Zhang Yu suddenly shouted at me, "Qin Xiaoke, quickly turn on the switch, someone will send corpse worms to your uncle and them again."

When I heard this, I was shocked, and hurriedly grabbed the pull ring attached to the stone with both hands, so to speak, using the strength to feed, and pulled it up vigorously.

Little by little, the ring pulled up, and the sound of the gears turning echoed in my ears, and the whole ground began to shake. As soon as I let go of my hand, I felt something at my feet, and I was shocked that it was a corpse worm, and a large number of corpse worms were attacking me again.

I jumped on the hemp rope on the side, and I wanted to jump on the opposite side of the road, but I was surprised to find that the rope could be extended through a round wheel. My whole body began to fall uncontrollably.

Boom!

Seeing that I was still five meters above the ground, after a pause, I hurriedly let go and fell onto the sand.

At this time, my first feeling was how could there be so much sand under me, which was considered to have saved my life. As soon as I stood up, I only heard the sound of "salsa" coming from both sides of the wall.

Zhang Yu and others ran over, and my uncle hurriedly walked towards me, opened the bottle that had stood on the stone slab before, took out a stream of stinking black mud, and wiped it on my face, arms, and clothes, "Xiao Ke, what did you touch?"

As soon as the black mud smeared on me, the black worms that were about to attack me suddenly dispersed to the side. I glanced at my uncle blankly, and then I saw two holes the size of skulls suddenly appear in the stone walls on both sides of us. The big guy and the little K took their coats and wrapped them into fists and desperately began to plug the holes, but to no avail.

Can't hold it!

First Xiao K shouted, and then the big man couldn't hold it anymore, and the sand sloped down from the stone walls on both sides like spring water.

I froze in place, "Isn't this the exit mechanism?" ”。

The sand was getting more and more, it was already slow to the waist, and the ladder was useless because it had no support points, and we were completely trapped in it. I held the sculls in both hands, and my mind kept thinking, "Is this the end of it?" ”。

At that moment, I felt my feet shake violently, and I heard the sound of gears turning in my ears. I saw that the sand holes in the stone walls on both sides closed automatically, and the sand around us began to disappear rapidly.

Before we knew what was going on, we all fell down and fell to a large net below.

We all saw a hint of surprise in each other's eyes, and we all shot upwards with flashlights. I saw that the ground where we were standing suddenly split in two, and a huge mouth appeared. When there is not much sand left, it begins to heal slowly.

As I looked at it, I couldn't help but think of a book I had read earlier. One of the blueprints in the book is similar to what we just came across.

Suppose there are two huge rectangular magnetic plates. The two magnetic plates attract each other and lean against each other to form a larger rectangular magnetic plate. Now, two holes are drilled in each of the sides of the two magnetic plates, and the magnetic plates are hoisted with the help of steel cables, which is like the swing we played with when we were children.

Let the steel cables on both sides be L, M respectively, and the magnetic plate is N, then Lmn will form a plane S.

There are huge grooves on the periphery of the surface S, that is, on both sides of L and M, which are filled with sand.

Now a few of us stand on the magnetic plate and apply a downward force to the magnetic plate as f, assuming that the maximum support force that the board can withstand is p.

p is much greater than f, but now because of the large amount of sand overflowing, the gravity of the sand and us far exceeds the supporting force p.

I had a series of associations in my mind, and when Zhang Yu touched me, I became thrilled, and then I realized that I was still lying on the giant net.

The old man and the others below me looked at me with a puzzled expression, I smiled awkwardly, the surroundings were not very dark, and looked around. We were on a boulder, surrounded by a dark river that stretched as far as the eye could see. At the edge of the boulder stood four straight pillars, and the net was pulled into the air, and we were spared. A small boat was tethered to a boulder, which was a feeling of the importance of the double pulp, but fortunately it was not lost.

I jumped off, and my uncle motioned for me to wash off the stinking sludge from me with water, and I waved my hand and smiled, "It's okay."

There was no way out around, we had no choice but to rely on that small boat, we had no choice, we rested for about five minutes, drank some water, ate some food, and had a strong overdraft in our bodies before. Then my uncle motioned for us not to stay here, fearing heresy, and jumped into the boat and rowed in the direction ahead.
