Xiao Fei looked triumphantly at the fallen to the ground and the broken arrows, weak, weak and unwilling, in a good mood, it is estimated that there will be no wind and grass for the time being, the wind is loud, and he is no longer afraid, and he is about to stride to the front of the black coffins that are close at hand, and he excitedly wants to reach out and open it, wanting to see it.

Wang Gongzi suddenly shouted in shock: " Xiao Fei, don't get close, everyone is very careful, in fact, these lifelike coffins we see in front of us are all fake, because I just saw that their positions have moved slightly, if it is a real thing, it is not moving, and I just almost ignored a problem between the ten thousand arrows, that is, when the drone touched the lid of the coffin, it was silent, quietly, very abnormal, as the saying goes, soldiers are not tired of cheating, I think this must be the tomb owner's delaying tactics, luring the enemy to go deeper, so the trick is repeated。 I think that the coffins we see are not real, but fantasy, like a mirage, ethereal, so when we just used the drone to check the poison, it was actually non-toxic, because the root cause is that there is nothing there, so the drone is checking the air, which naturally shows that it is non-toxic. ”

Hu Jiaojiao also said delicately: "That's it, I just wondered, the black coffin that looked close just now, it still feels out of reach after walking for a long time, it's really strange, it shouldn't be, now that I think about it, it's true." ”

The prince thought for a long time, and said incredulously: "Everyone be careful, don't rush to the front, care is chaos, so what we see is just a mirage, it is an ecstasy array, the real coffin is not in the front place, be careful is a maze array, let us stray into the trap." ”

Xiao Fei's face turned white with horror: "It's really dangerous, but if you don't die, there will be a blessing in the future, it's really a god bless, God bless, Allah bless——"

After all, Xiaofei is a boy, and he is quite interested in science, and he swears to me triumphantly: " I don't understand, let my brother tell you, this light has been refracted many times but has not been lost, and it happens to be refracted back for people to see, when the light is carried out in a uniform medium of the same density, the speed of light does not change, it moves in a straight direction, but when the light obliquely enters another medium with different densities, the speed of light will change, and the direction of progress will also be tortuous, this phenomenon is called refraction.

Air itself is not a homogeneous medium, in general, its density decreases with the increase of memory, and the higher the height, the smaller the chin. When light passes through layers of air at different heights, it always causes some refraction, but this refraction phenomenon is used to in our daily life, so we don't think it's anything unusual. However, this phenomenon occurs when the air temperature changes abnormally vertically, resulting in a different refraction and total reflection than usual. The abnormal distribution of temperatures is the meteorological condition for the formation of most mirages. In the summer desert when the scorching sun is headed, the sand is scorched, because the specific heat of the sand is small, the temperature rises very quickly, the temperature of the lower air near the sand rises very high, and the temperature of the upper air is still very low, so that the abnormal distribution of air temperature is formed, due to the thermal expansion and contraction, the density of the lower layer of hot air close to the sand is small and the density of the upper layer of cold air is large, so that the refractive index of the air is small in the lower layer and large in the upper layer. When the light reflected by a distant higher object is constantly refracted from the denser air in the upper layer into the sparse air in the lower layer, the angle of incidence gradually increases, and when it increases to an equal to the critical angle, total reflection occurs, at this time, if people look at the reflected light in the opposite direction, they will see the mirage. In the desert, the sand and gravel 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. ”

I asked curiously, "What is the strange palace maid incident in 1992 when there was a thunderstorm and was photographed by many tourists, and after obtaining favorable evidence, it is really unbelievable? Is it also a mirage?"

Xiao Fei said smugly: "Those are two different things, not the same day, experts have given a scientific explanation, the Forbidden City can see the palace maid There is a scientific basis, because the palace wall is red, containing ferric tetroxide, and lightning may conduct electrical energy down, if there happens to be a palace maid passing by, then at this time the palace wall is equivalent to the function of the video tape, if there is a lightning coincidence in the future, it may be like a video projection, the shadow of the recorded palace maid will appear." ”

Wang Gongzi interrupted our whispering, and after careful observation, he said: " Let's not make a fuss, don't talk, or be careful behind you, we still continue to fly over the wall as we just did, and arrive at a relatively safe area in front, everyone should be vigilant, and the farther away from those fake coffins is better, so that they can be safe and sound, and turn the crisis into safety, because this tomb owner is too cunning, too cunning, and it is impossible to prevent it, and I think that most of these coffins are used to psychedelize us who trespass into the tomb, this tomb owner wants to be surprised, and the soldiers are surprisingly expensive, so I dare to 100% conclude that there must be many mechanisms under this coffin, thrilling, and dangerous。 ”

Sure enough, after we arrived safely in front of the distant safety zone, Xiao Fei casually threw a heavy object into those coffin groups, Mingshu and those coffins had a fierce collision, but there was no sound at all, quietly, all silent, it was really a mirage-like fake coffin, but the heavy object was thrown down, those organs moved when they heard the sound, slammed open, and the big hole like an abyss was unobstructed, and the 10,000 tons of wild sand in the surrounding gaps were like galloping endlessly for a while, and the yellow dragon of ten thousand horses galloped out, passionate, unscrupulous, and galloped as you liked, pouring out like a river of sand, Soon the big pit under the fake coffin was quickly filled, and then the dexterous mechanism triumphantly continued to close quietly as before, those fake coffins continued to be safe and sound, lifelike, energetic, eyebrows fluttered and reappeared in front of us, it turned out to be a sea of sand, a method commonly used in ancient times to prevent and control tomb robbery, and there is an immediate effect, if we can't wait to go inside, we will definitely be lured to the enemy deep, buried in those heavy sand, breathing difficulty, simply buried alive, and finally evolved into a pile of white bones covered with skin and bones, it seems that this tomb owner is really not simple, most likely a great general is undoubtedly, this uncle is really resourceful, familiar with military books, familiar with the art of war, and strategizing, it is really not simple, we should not underestimate it.

Hu Jiaojiao said with palpitations: "And this tomb is really too heavy, too eerie and terrifying, there are mechanisms everywhere, there are ambushes everywhere, we have to be careful, but we have to be careful." "Fortunately, we came prepared, carefully bypassing the mirage just now, but now it is a dangerous area like walking on the ground, there is no way back behind us, we can only move forward bravely, go forward, bravely enter the tomb, we are all frightened, looking left and right to continue to walk to the deep tomb inside-
