Guan Zheng asked Guan Nuo: "Look at the weather recently?" ”

Guan Nuo said: "I was about to tell you about this, the weather has been very bad lately, there are sandstorms, and there may be dust storms. ”

Xu Jiuyan asked suspiciously, "Eh, is there a difference between a sandstorm and a dust storm and the sandstorm we are talking about?" ”

"Sandstorms are a general term for sandstorms and dust storms, and are a sign of desertification. It refers to a disastrous weather phenomenon in which strong winds roll up a large amount of sand and dust from the ground, making the horizontal visibility less than a kilometer, and having the characteristics of suddenness and short duration. Among them, sandstorm refers to the sandstorm formed by strong winds blowing a large amount of sand into the near formation; A dust storm is a storm formed by high winds that sweep large amounts of dust and other fine particles into the air.

Sandstorms are common in China's northwest and north China, and the natural conditions for the formation of sandstorms are mainly strong winds, strong thermal instability and sand sources, and non-natural factors are unreasonable land use and natural factors by human beings, and sandstorms mostly occur in winter and spring. Sandstorms will not only pollute the environment and affect production and life, but also pose a threat to people's lives and property. ”

Lao You has seen a lot of the world, and he doesn't feel worried or anything, but laughs and says: "Anyway, there is a political master with us, but there is no need to worry about the sky, what do you say?" ”

Brother Chuan also laughed and said, "Director You is right! ”

Guan Zheng looked at the dust around him and said, "Let's all get in the car and rest, and we will leave when the sandstorm is over." ”

Everyone got into the car one after another, closed the door, and the car was very quiet for a while, and even the sound of everyone's breathing could be heard clearly. Guan Nuo hugged the computer and said, "Do you think it's strange, there is no signal here now." ”

"What did you say?" All the staff, including Guan Zheng, were amazed.

Everyone took out their mobile phones one after another, but there was really no signal. Xu Jiuyan asked curiously, "What's going on?" Why is there no signal? ”

Guan Nuo shook his head and said, "I really don't know this, but it's okay, I left a backup move." ”

Guan Nuo took out several walkie-talkies from the small box behind him and said, "Look at this!" ”

Xu Jiuyan screamed happily: "It's so amazing, you, have you thought of it?" ”

Guan Nuo smiled and said, "Be prepared!" Walkie-talkie is a two-way mobile communication tool, which can talk without any network support, without phone charges, and is suitable for relatively fixed and frequent calls. Not only that, but I also installed a car walkie-talkie on these two cars, which is placed right behind the car display, hidden, right? ”

Guan Nuo tinkered a few times and said into the walkie-talkie: "Brother Chuan, there is a walkie-talkie in the car, and one person will send it to everyone." ”

Brother Chuan immediately took out the walkie-talkie and said, "Guan Nuo, you are amazing, this has helped us a lot." ”

Guan Nuo smiled and said, "It's a gesture." ”

The storm outside was getting more and more ferocious, and even a wall of sand appeared. Guan Nuo said: "Most of the strong sandstorms on the mainland move from the northwest or west, and a few from the east. When almost all sandstorms come, we can see black walls of wind and sand moving rapidly in the direction where the wind is blowing, getting closer and closer. From a distance, the wind and sand wall is as tall as a mountain, very much like a city wall, also called the wind and sand wall, which is the front of the arrival of the sandstorm.

When a strong sandstorm occurs, the wind is very strong due to the wind blowing above level 8, which can roll up stones and sand. As more and more sand and dust flew into the air, the dense sand and dust covered the sky, blocking the sun and making it impossible to see anything for a while, as if at night.

When the black wind blows, the air near the ground is very unstable, and the heated air below rises, and the surrounding air flows to replenish, causing the air to carry a large amount of sand and dust to roll up and down, forming countless dust balls of different sizes in the air.

The upper layer of the aeolian sand wall is often yellow to red, the middle layer is grayish-black, and the lower layer is black. The yellowing and redness of the upper layer is due to the fact that the dust in the upper layer is thin and fine-grained, and the sunlight can almost pass through the dust and shoot down. The lower layer of sand and dust has a large concentration and coarse particles, and the sunlight is almost completely absorbed or scattered by the sand and dust, so it is black. Where the wind and sand walls moved, the sky was changing from light to dark. This is caused by the light passing through a band of sand and dust of varying thicknesses and thicknesses. So the sandstorm is very beautiful, and we all have a good eye. ”

Xu Jiuyan shook her head and said, "I'd rather never see it for the rest of my life." ”

But everyone didn't expect that the wind of this sandstorm was extremely strong, and seeing that the Yadan stones in the distance had been rolled up, Guan Zheng found that there might be a crisis.

Guan Zheng told everyone: "Everyone must fasten their seat belts, grasp the handrails, if the car rolls over, you must pay attention to safety, do not move, and wait for everything to calm down before acting." ”

"Understood!"

The sand and dust swirled and flew into the sky, and a wall of wind and sand swept over quickly, directly rolling up the two cars, and Xu Jiuyan panicked and felt that the cars had taken off, as if they were still moving. Guan Zheng said: "Don't panic, hold the handrail, pay attention to safety!" ”

There was nothing to be seen around, there was sand outside the window, and nothing could be seen. Feeling that the car has not changed its shape, which is good news for them.

When everyone felt the car touching the ground, they slowly opened their eyes once. The windows of the car had been sealed with sand, and Guan Zheng took the lead and said, "I'll get out of the car and take a look." ”

Xu Jiuyan suddenly grabbed Guan Zheng and said, "Is there something on the car door on my side?" ”

Guan Zheng was so frightened that he was about to cry when he saw Xu Jiuyan, and said, "What can there be?" Here in the wilderness. ”

Xu Jiuyan said very firmly: "It's just something!" ”

Guan Zheng had no choice but to say, "You go to the back seat, and I'll open the door." ”

Xu Jiuyan nodded, stepped into the back seat, Guan Zheng drilled into the co-pilot's position, looked at everyone, and then plucked up the courage to push the car door.

Guan Zheng pushed the car door, except that the door was a little heavier, there was nothing else abnormal, but what made Guan Zheng feel strange was that the environment around here had all changed.

When you look out of the door, they seem to be in the ruins of an ancient city, surrounded by adobe left over from very old civil engineering buildings, and there are no houses at all, but they make people feel like they are in the fireworks.

Guan Zheng got out of the car, glanced at the door, made a quiet gesture, and then gestured: "You sit down, don't come down." Several people did not know the reason, and sat in the carriage in a panic and timidity.

Guan Zheng took out his gun and walked lightly along the car, but there was nothing abnormal. But Xu Jiuyan saw it......
