Guan Zheng asked Guan Nuo: "Look at how the weather has been recently?"
Guan Nuo said, "I'm about to tell you about this. The weather has been very bad recently, with sandstorms and possibly dust storms."
Xu Jiuyan asked suspiciously, "Uh, are sandstorms and duststorms different from what we said about sandstorms?"
Guan Nuo explained: “Sandstorm is the general term for sandstorms and duststorms, and is a sign of desertification. It means that strong winds lift up a large amount of sand and dust from the ground, making the horizontal visibility less than one kilometer, and the probability of being sudden and short-lasting is small. A catastrophic weather phenomenon with great hazards. Among them, a sandstorm refers to a sand-laden storm formed by strong wind blowing a large amount of sand into the near-surface layer; a dust storm is a storm formed by a large amount of dust and other fine particles being drawn into the high altitude by a strong wind.
Sandstorms are common in Northwest China and North China. The natural conditions for sandstorms are mainly strong winds, strong thermal instability, and sand sources. Unnatural factors are unreasonable human land use and natural factors. Sandstorms mostly occur in winter and spring. Sand and dust storms will not only pollute the environment and affect production and life, but also threaten people's lives and property safety. Preventive measures are what we often call tree planting and reforestation. "
Lao You sees a lot of the world, and he doesn't feel worried about anything. Instead, he smiled and said, "Anyway, there are political masters with us, so there is no need to worry about the world, what do you think?"
Brother Chuan also laughed and said, "Director You is right!"
Guan Zheng looked at the surrounding sand and dust, and said, "Everyone get in the car and rest. We will leave when the dust storm passes."
Everyone got in the car one after another and closed the door. The car was quiet for a while, and everyone's breathing was clearly audible. Guan Nuo held the computer and said, "Did you find it weird, there is no signal here now."
"What did you say?" All personnel including Guan Zheng were surprised.
Everyone took out their phones one after another, but there was really no signal. Xu Jiuyan asked curiously: "What's the matter? Why is there no signal?"
Guan Nuo shook his head and said, "I really don't know about this, but it's okay. I've left for a later move."
Guan Nuo pulled out several walkie-talkies from the small box behind him and said, "Look at this!"
Xu Jiuyan screamed with joy: "So amazing, you, did you think of this?"
Guan Nuo smiled and said: "Be prepared! Walkie-talkie is a two-way mobile communication tool that can make calls without any network support. There is no call charge. It is suitable for relatively fixed and frequent calls. Not only that, I I also installed a car intercom on these two cars, placed behind the car display, concealed?"
Guan Nuo fiddled a few times and said to the walkie-talkie: "Brother Chuan, there is a walkie-talkie in the car, and they will be sent to everyone one by one."
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 little effort."
The storm outside became more and more fierce, and even a sand wall appeared. Guan Nuo said: "Most of the strong sandstorms on the mainland move from the northwest or west, and a few move from the east. When almost all sandstorms come, we can see a black sandstorm wall in the direction where the wind blows. Moving, getting closer and closer. From a distance, the sandstorm wall is as tall as a mountain, very much like a city wall, also called the sandstorm wall, which is the forward of the sandstorm.
When a strong sandstorm occurs, due to a strong wind of level 8 or above, the wind is very strong and can roll up rocks and sand. As more and more dust fly into the air, the dense dust covers the sky and covers the sun, making people invisible for a period of time, just like at night.
When the black wind is blowing, the air close to the ground is very unstable. The heated air below rises up, and the surrounding air flows to replenish it. This has caused the air to carry a large amount of sand and dust to roll up and down, forming countless sand and dust clusters of different sizes. Converge in the air and surge.
The upper layer of the sand wall is often yellow to red, the middle layer is gray-black, and the lower layer is black. The yellowing and redness of the upper layer is due to the thin dust and fine particles in the upper layer, and the sunlight can almost pass through the dust and shoot down. The lower layer of sand and dust has a high concentration and coarse particles, and almost all sunlight is absorbed or scattered by the sand and dust, so it turns black. The sky moved by the sand wall, the sky is bright and dark, constantly changing. This is caused by light passing through sand and dust belts of varying thickness and density. So the sandstorm is very beautiful, we all have eyes. "
Xu Jiuyan shook her head and said, "I would rather never see it for a lifetime."
But everyone did not expect that the wind of this sandstorm was extremely windy. Seeing that the Yadan stones in the distance had been rolled up, Guan Zheng discovered that there might be a crisis.
Guan Zheng said to everyone: "Everyone must wear seat belts and grasp the handrails. If the car rolls over, you must pay attention to safety, don't move, and wait for everything to calm down before acting."
"clear!"
The sand and dust flew up into the sky in a whirl, a windy sand wall quickly swept over, and directly rolled up the two cars, Xu Jiuyan panicked that the cars were already empty, as if they were still moving. Guan Zheng said: "Don't panic, hold the handrails and pay attention to safety!"
Nothing can be seen all around, the window is full of sand, and nothing can be seen. In terms of feeling, the car has not undergone a morphological change, which is good news for them.
When everyone felt the car touched the ground, they opened their eyes slowly. The windows of the car have been sealed with sand, and Guan Zheng first said: "I will get out of the car and have a look."
Xu Jiuyan suddenly grabbed Guan Zheng and said, "Is there something on my car door?"
Guan Zheng saw Xu Jiuyan so scared that he almost cried, and said, "What can be there? It's in the wilderness here."
Xu Jiuyan said very firmly, "I just have something!"
Guan Zheng had to say: "Go to the back seat and I will open the door."
Xu Jiuyan nodded, stepped into the back seat, Guan Zheng got into the position of the co-pilot, looked at everyone, and then plucked up the courage to push the car door.
Guan Zheng pushed the car door, and there was nothing unusual except that the door was a bit heavier, but what made Guan Zheng feel strange was that the surrounding environment had all changed.
Everyone could see from the car door that they seemed to be in the ruins of an ancient city, surrounded by adobes left by very old civil constructions. They didn't look like houses at all, but they made people feel smoky.
Guan Zheng got out of the car, glanced at the car door, made a quiet gesture, and then made a gesture: "Sit down, don't get down." A few people didn't know the reason, and sat in the car in panic and timidity.
Guan Zheng took out his gun and walked gently along the car, but nothing was unusual. But Xu Jiuyan saw... (End of this chapter)
