If you want to say that the desert silver lonely, everyone knows everyone in the desert, but there are not too many people who have really seen it, some say that the desert silver lone is a big man, and some people say that the desert silver lone is the tent man, although there are countless famous people who have died in his hands in the past few years, and he himself has long been famous, but so far, no one who has lived has seen his true face, and all his dealings with the outside world are managed by those two people. Pen ~ fun ~ Pavilion www.biquge.info didn't expect it to be cut in Topaz's hands this time.

Topaz and the others continued to move forward, surging forward one after another, like an invisible giant hand, peeling off the desert layer by layer, and layer after layer. The sand under the scorching sun, revealing a trace of heat, looking up, it seems that the yellow sand under your feet is floating with a faint and continuous heat wave, and the soles of the camel's feet leave a walking mark in the desert. Under the scorching sun, the Gobi Desert is like roasting on a stove, and the scorching heat wave sweeps every inch of land, making people breathless. The vast desert, the dead sea of sand. Majestic, quiet, with a straight face, always gives you a monotonous color: yellow, yellow, always a scorching yellow. It is as if nature has frozen the turbulent waves and the empty angry waves here in an instant, making it stand still forever. Nature has laid a yellow carpet here. When the wind blew, it was as if someone was shaking the carpet, and the sky was full of dust and smoke. There is a whirlwind in the desert, one by one, rolling up the yellow sand so high that it is like a big smoke rising from the flat ground, and it is running around the desert. The sky is blue, the earth is yellow, and there are no other colors to be seen here except blue and yellow.

At this time, Topaz and they suddenly saw a lonely pagoda in front of them, towering high into the sky, Topaz, Xiao Zhaohua and others, you look at me, I look at you, and they are surprised and puzzled, thinking that there is a temple in the desert. Not long after, I saw dozens of palaces, the tiles were turquoise, and the eaves were raised high. Not long after, the high and low city walls appeared, stretching for six or seven miles, and it turned out to be a city. There are like pavilions, some like halls, some like neighborhoods. Suddenly, a strong wind blew, and the whole city became blurred. After a while, the wind stopped, the sky cleared, and the previous scene was all gone, and a large lake appeared, which was filled with clear blue water, which did not seem very far away. When the topaz and the others happily ran towards the big lake, there was always a distance between the blue lake, the so-called "hopeless but unattainable". The guide said: "Note that this is the Devil's Sea, in the desert, the sand and rocks are scorched by the sun during the day, and the temperature on the surface of the sand layer rises rapidly. Due to the poor heat transfer performance of the air, when there is no wind, the vertical air temperature difference over the desert is very significant, the lower is hot and the upper is cold, the upper air density is high, and the lower air density is low. When sunlight enters the dense air layer from the dense air layer, the speed of light changes, and the light is refracted to reveal the distant oasis in front of people's eyes. If the temperature of the air near the ground is low and the upper layer is high, with a difference of 7 to 8 degrees Celsius over a short distance, as is sometimes seen in a straight seaside area, then all the islands and people that are not normally seen below the horizon can be reflected in the sky, and it is located in the "ethereal space", also known as the devil's sea. In the Devil's Sea, the natural features are blurred, making it difficult for a person to distinguish distant objects, and at the same time blurring the outline of the distant vision, you feel as if you are surrounded by a piece of water, and the higher part of the area looks like an "island" in the water. However, if you go to a higher place about 3 meters above the desert floor, you can avoid the hot air close to the surface and overcome the illusion of the devil's sea. In short, with a slight adjustment of the height of the view, the phenomenon in the sea of the devil will disappear, or its appearance and height will change. All in all, this is a very interesting refraction phenomenon. Just like if you look at a fish in the water, the light is refracted at the surface of the water, and the refracted light enters our eyes, and what we see is higher than the actual position of the object, and this is the same thing. ”
