Chapter 453

Looking at the sun, I took out a knife and stuck it in the sand.

When the sun shone, I could see the shadow of the knife. I pressed the shadow with the small stone in front of me. After waiting for about ten minutes, the shadow of the knife moved three or four centimeters like the left. I brought Douyazi's knife and gestured to make a cross on the position of the small stone.

The shadows of the two swords alternate, and the direction of the cross head is the West.

I stood up and pointed at the West: "Walking there, even if it takes more than a little bit of time, I will definitely get there when I go west."

We must still be in Tengger now. We can only reach Badain Jilin when we go west. Those who come to the south of Badain Jilin. If we go to the north in the wrong direction, the final result will be to keep walking and finally arrive in Ulan Buhe, and then we will leave Inner Mongolia.

After confirming the direction, everyone moved forward again. At this time, the climate conditions were much worse than those in two or three months. Sandstorms were frequent every year before and after winter and after spring. Just statistics show that in 2000, there were 46 sandstorms in Ningxia, and more than 60 in 2001. That is to say, Ningxia put in the Three North Shelterbelt System Construction Plan, and additional investment in the Three North Shelterbelt Plan for Supplementary Plan for Farmers to Plant Trees and Afforestation, reducing the impact of Ningxia sand sources on the dust climate in Beijing.

Everyone rested early that night. The wind was whistling outside, just like a ghost crying. The wind was getting heavier and heavier. The small tent we had shaking left and right. I didn't dare to sleep anymore, so I covered my mouth and nose with my clothes and ran out to ask everyone to get up and collect the tent, and stop shaking it.

"What! Say something!" Douyazai patted his head and covered his mouth and shouted at me.

"Opening|官网! I collected the tent!" I shouted at him anxiously.

Douyazi heard it clearly and ran to collect the bills.

Liao Xiaomi was blown forward by the wind, and Liao Bo grabbed him.

I secretly prayed that God should not shave it, and that it would become a sandstorm when it was big, and that would be over.

I don’t know if I heard my prayer, but the gust of wind lasted for more than half an hour, and gradually became smaller. The wind was a little bit louder and sand became smaller, and people could finally open their eyes.

Just then.

"Don't make a sound..."

"Listen."

The wind was getting low, and I suddenly heard a strange sound, with a low tone. At first it was like a mouse's cry, squeaking, and after a few minutes it looked like a frog's cry, croaking.

I thought there was a hallucination in my ears, but when I saw Brother Yu’s face was surprised, I knew that he must have heard it too.

What kind of territory is this? Here is a dry and smokey Tengger, without any water, how could there be a frog?

After listening carefully for two minutes, I felt that the sound was not very similar to the sound of a frog. If it was a frog, it would be rhythmic and croaking. This is different. This sound did not fluctuate from beginning to end, and always maintained a tone.

The sound came from behind us. Brother Yu was very curious and said to go over and see what happened.

I said be careful with Brother Yu.

Brother Yu waved his hand and said it was okay, he was just curious.

Following the direction of the sound, we followed him back. After walking for less than ten minutes, the more we walked, the more clearly the sound became. Finally, we stopped in front of a big sandbag.

Strangely, the sound of croaking came from the sandbag.

It’s okay to say sandbags and sand dunes are okay. I have seen this place during the day. It seems not so big. Now it’s so big. I guess it’s blown by the wind.

Douyazai widened his eyes and said, "Is there a nest of frogs living in the sand?"

Brother Yu exclaimed and said what was going on. He picked up a stone, threw it away, and smashed it into the sand dune.

The stone was thrown in. After more than ten seconds, the croaking sound changed, making a sound similar to a bass erhu, which was very strange.

At this moment, Liao Xiaomi suddenly raised her hand and said, "I know, is this a loud sand dune? I have heard someone say that there is a loud sand dune in Tengger."

Later, after my verification, it may be such a loud sand dune. It was the first time I saw it with my own eyes and found it very interesting.

The so-called loud sand refers to sand that can make noises. The sound emitted by the sand dunes will change due to external forces. There are many different opinions on the formation of this sound, and scientists say it differently. The general meaning should be related to the flow of static electricity inside the sand. Later, a classic legend from Jiangxi TV station filmed a similar episode of the sound sand, but they didn't understand it.

Our group played there for a long time. When we stepped in, we could hear the sound of the plane flying by. When we sat in, we could hear the sound of the donkey screaming.

As we played, the fatigue on everyone's faces was also wiped out.

When the wind stopped, the sand dunes gradually stopped.

This strange and fun sound is gone.
