We didn't turn off the lights. We didn't bring any lighting tools with us. We couldn't explore the terrain around. The temperature here is much warmer than the mysterious space. With the soft sand under my body, I feel very comfortable and comfortable at the moment. I close my eyes and go to sleep.

My friend had another dream that he and LAN Xiaoying finally confessed that the agreement between us had become a reality. They walked hand in hand on the beach. Suddenly, the beach turned into an ice river and LAN Xiaoying suddenly disappeared. I looked around in a hurry and finally saw her ferocious face under the ice!

At this moment, he was suddenly awakened. As soon as he opened his eyes, he was stabbed by a burst of strong sunlight and closed his eyelids. I turned around and sat up. I looked around. LAN Xiaoying and Chen Xi slept soundly, so I put my heart in my stomach. Then look around. This is a sand field. There are excavators and houses in the distance. Behind it is a desolate mountain.

Then look up at the direction of the sun. It should be 9 a.m.

At this time, the excavator in the distance woke Chen Xi and LAN Xiaoying. They rubbed their bleary eyes and didn't know where they were.

When the excavator came to the front, the driver threw a cigarette end from inside and scolded, "his grandmother's, why do three beggars sleep here? You don't want to die?"

I quickly smiled and said, "brother, we are not beggars. We lost our way in the mountain last night..."

Before I finished, the driver opened his mouth and scolded: "fart! Into the mountains? How? Do you know what is behind this mountain? "

The three of us shook our heads at a loss. My heart said that there would not be a labyrinth valley behind the mountain. Can't anyone get in?

The driver looked at us and said, "there is a deep valley behind the mountain. Let alone people, birds can't fly over. Get out of here and don't delay my work. "

The three of us nodded, bypassed the excavator, went far ahead and went up the hill from the other side. The mountain is not very high. It's more than 200 meters above sea level. It's easy to go up. Lying on the top of the mountain and looking down, the three people fought a cold war at the same time. It's too deep down, just like the back mountain of Shiyan village.

But the gully area here is quite vast, forming an endless basin. It's not an exaggeration to look at the situation where the clouds and fog are shrouded and the bottom is not seen. It's impossible for birds to fly.

The three of us looked at each other in amazement and said, were we down here last night? No, if it's down there, how did it fly out? We are not ghost trains. We can go from heaven to earth. Four living people can't fly so high with two wings.

After looking for a while, I didn't see a reason. However, the three people were hungry and hurried down the mountain. Let LAN Xiaoying clean her face and go talk to your driver. Even if he is a beggar, it is impossible for a man not to be indifferent to this beautiful face.

The driver immediately looked straight and changed his attitude 360 degrees. LAN Xiaoying said she was really lost. She lives in Huangyu city. Now she can't find a shop in front of the village and behind. She asked her brother to help us and give us something to eat first. The driver jumped off the excavator and took the three of us to the dormitory.

This guy is in his thirties. In fact, he is not a good man, but the folk custom in the mountain village is fierce and has a big temper.

When we got inside, this guy gave us some steamed buns and ate them with pickles. The man was hungry to a certain extent, and the grass roots tasted delicious, not to mention the white steamed bread. I grew up with snacks, steamed bread and pickles, but I've never felt so delicious. It's almost more delicious than delicacies!

The three of us almost didn't eat the driver's brother and cry. Chen Xi and I ate five steamed buns and LAN Xiaoying ate two. Drinking cold water after eating is incredibly comfortable.

LAN Xiaoying asked, where is this place? The driver said that it is 150 kilometers away from Huangyu city and is basically close to the boundary of Shandong Province. This place is rich in yellow sand. There are sand fields everywhere. After passing the North Road, it is Shashan town. So I borrowed the driver's brother's cell phone, called Huasi and asked her to pick us up.

I know Shashan town. I've seen this place name on the map. It is located in the southeast of Shiyan village, about 50 kilometers apart. But I haven't heard of the basin behind the sand field mountain.

The driver then told us that there was a large basin behind the mountain, which was called "black sand pit" by the locals. It is said that it used to be a plain sandy land. Later, after a strong wind, there were ten thousand deep pits on the ground. The sand was blown to the north and piled up this Sand Mountain stretching for tens of miles.

A scientific research team has visited the basin before, but it can't go down at all. Although there is a slope on the South Bank of the bunker, there is a strange strong magnetic field and gravity on the slope. After a few steps down, it will roll back up the slope. Then he tried his best to break through the mysterious magnetic field, and finally failed. So far, no one knows what is going on at the bottom of the pit, but in spring, black tornadoes will blow from the bottom of the pit and roll into the sky, blocking out the sky and the sun. The momentum is very amazing. That's the name of the black bunker.

After listening, I thought, are we at the bottom of the pit and finally sucked out by the gravity of a strong magnetic field?

There are many strange things in the world that scientists can't explain up to now. For example, there is a "gravity mountain" slope in the United States. When you drive down the slope, the car will go up the slope by itself, which is as magical as sliding down the slope. There is also a strange slope on Jeju Island, South Korea. The car stalled here and slipped up along the ramp.

What science can't explain is often given the theory of gods and ghosts, but it can't be denied that there are no ghosts. Like the black sand pit behind the sand mountain, I always feel that the Tiankeng trapped by the train is right below. Because the distance from the train missing here is not too far, and this possibility is very high.

LAN Xiaoying asked again, did the black bunker take people's lives? The driver said that few people died because they couldn't get off. Only when there is a Black Whirlwind will someone close here be sure to disappear. However, there will be no accident on the battlefield. This mountain is blocking the wind. No one has died on the battlefield for many years.

Then the driver's brother said some local anecdotes, but it had little to do with the black sand pit, and we were not interested in listening to it again. He went out to bask in the sun, and the driver went on to work. Wait until the morning, Huasi personally drove to the battlefield.

The driver was stunned at the sight of the luxury car and the elegant appearance of the flower shop. I must be thinking that 200% of the three people are beggars just now. Why do beggars have such rich friends?

Before leaving, Huasi heard that we ate more than a dozen steamed buns from others, and immediately photographed a handful of money as the cost of meals. The driver's eldest brother was very kind and said that only a few steamed buns were free.

Hua Si stared and said, "take it! Or I'll buy this battlefield today and let you lose your job! "

The king was so domineering that he immediately stunned the driver. He didn't move until we got on the bus.
