We can't wait to run to the three bridges of the Tianshan Mountains, and soon arrive at the destination, but unfortunately this is not a modern society, there are automatic elevators directly up and down, there is nothing here, so we have to go down carefully along the steep cliffs, look down from above, below is a huge big stone pothole, it is really like an abyss, people shudder, frightened, we have gone through a lot of hardships, dangerous rock cliffs, and finally come to the bottom of the bottomless valley, there is really a hole in the sky, there is a kind of mountain and water are doubtful, the willows and flowers are bright and the feeling of another village。 And the scenery at the bottom of the valley is very different from the scenery above, as if coming to a new world that I have never come to, isolated from the world, forgetting everything, as if I have come to a strange shape, incredible place, bare stone walls, thousands of walls. The circular valley floor is reminiscent of the round Colosseum of ancient Rome. We couldn't help but look upward, feeling that looking at the sky in the valley was really like a frog at the bottom of a well looking at the sky, the sky was high and narrow, the cliffs were precipitous, and the cliffs were ringing, and I don't know why I suddenly thought of the majestic Colosseum of ancient Rome.

We walked in the open valley, which seemed so small compared to the magnificent cliffs on either side. Looking up, there is a black pressed rock, and that is the bridge deck. Mankind has built countless bridges over the ages, which one has such grandeur and such momentum! I feel that this situation and this scene are very shocking, strange rocks, completely like the masterpiece of aliens, and marvel at the magic of nature, we people seem so small and insignificant in front of this magnificent, majestic, majestic masterpiece of nature, like little ants.

There is a natural stone bridge in front of you, this is the famous Tianlong Bridge, which is the only double-arch bridge among the three bridges, consisting of a pier and two bridge holes. It is also one of the three stone bridges that resembles an artificial bridge, the bridge cave wall on the left is boxy, very smooth, just like man-made, the magic of nature is breathtaking! Tianlong Bridge is majestic, the total height of the bridge body has reached 235 meters, of which the bridge thickness is 150 meters, the span has reached 75 meters, and the average arch height is 96 meters. Looking down through the opening, there is a flat green area surrounded by cliffs, and a path zigzags forward. Near the natural stone bridge cave, is an antique, black building, it turns out that this is the filming place of the modern social TV series "Full of Golden Armor", the famous Tianfu Station, unique, unique style, it is said that the post station was built in the second year of Tang Wude, it is an important post house for the official information transmission of Fuzhou and Qianzhou in ancient times, and the place where the official post is located is Tianlong Tiankeng. I stood in the open space of the sinkhole, surrounded by huge limestone cliffs like a knife cut in front of me and behind me, and the clouds above my head came and went leisurely.

The black pressed antique roof is shrouded by the abyss of Tianlong Bridge, the eaves hang the corners, beautiful, self-contained, surrounded by rocks, the shrubs are verdant, there is a deep and gloomy atmosphere, and the surrounding environment is integrated, not abrupt. So the choice really complements each other, and it is a rare shooting scenery. As I stand here at this moment, I can vaguely recall the thrilling and exciting scenes of the black-clad soldiers flying down the ropes in the movie. I finally know why the later Hollywood blockbuster, "Transformers 4", was still located here as a location, and it was filmed for half a year, which was really different and unforgettable at first sight. However, this post station in front of us is a real handiwork, and this post station in front of us in modern society was destroyed in the war, and it was rebuilt later, it is really ruthless in time, and we can't help but take a few more looks.

We didn't go too far, we saw at a glance that the front is the Qinglong Bridge, the Qinglong Bridge is the second bridge of Tiankeng, which is a Tiansheng Bridge with the largest vertical height difference, reaching 281 meters, which is the highest height of the karst Tiansheng Bridge in the world. Looking up from under the bridge, the arch hole is high and open, the wall stands thousands of thousands, the section of the top of the cave is arc-shaped parallel distribution, it is no longer a rugged mountain road here, but a flat and flat path, it is much easier and more comfortable to walk, we can't help but speed up the pace, walk briskly in the past. A small white gurgling stream accompanies us, adding a bit of lightness, beauty and agility to the sinkhole. It swirls not far from the bridge to form a small blue lake and then flows under the Qinglong Bridge along the trail. From a distance, the cave of Qinglong Bridge looks like a big knife reflected in the lake.

We can't wait to pass through the magnificent Qinglong Bridge Bridge and tunnel, and another wide area, that is, the Eagle Sinkhole. There is a surrounding cliff wall here with unique characteristics, the demeanor is clearly visible, it is like a mighty eagle stretching out its powerful wings upward, rushing out of the stone pit, rushing into the sky, vivid, lifelike, really like a real eagle. Then we finally strode to the last bridge of the Tiansheng Three Bridges, which was the Black Dragon Bridge. The bridge hole is deep and dark, and the rock at the top of the bridge hole is like a black dragon hiding here, which is terrifying. The Black Dragon Bridge is unique and famous for its three-fold springs, first-line springs, pearl springs, and fog springs with different flow patterns. Walking in the flat bridge cave of the Black Dragon Bridge, you can see the cliff wall towering, and all kinds of stalactites hanging on the stone wall. A few wisps of clear spring splashed on the cliff, turning into a drizzle, like a thin bead curtain hanging in the mountains, trickling through the Black Dragon Bridge and then gathering into a blue and quiet lake.

However, we walked around and looked at the flowers, looking for and seeking, people in Cao Ying's heart in Han, although the scenery at this moment is infinitely good, the heart is still thinking where the things are, so we lost no time to take advantage of the time when others did not pay attention to the use of various detection instruments, but there was no slightest discovery, we were disappointed to find that there was nothing here, it is estimated that it was in other places, they had a lot of fun, and watched tirelessly, and then we couldn't wait, and went to the crack in the ground non-stop.

We also went straight down about 80 meters along the steep cliff to reach the bottom of the deep and narrow valley, which is the famous ground crack, along the narrow ground crack can only accommodate one person in the cliff plank road, here is extremely deep and slippery, we carefully walk through the narrow and steep karst stone crevice, appreciate the grandeur and peculiarity of the Longshui Gorge crack.

Then we finally came to the mouth of a cave with a bloody mouth like a dragon. The endless flow of white water flowed out of the cave and flowed deep into the cracks in the ground, which was the famous Jiaolong Cold Cave. In the past, it was said that there was a dragon in the cave, so the crack in the Longshui Gorge was also named, and then became famous all over the world. It is the outlet of the underground channel that was gradually widened by the continuous dissolution of the rock along the cracks of the rock layer in the early days of the early groundwater hundreds of millions of years ago, so its section is irregular and trumpet-shaped, and its height and width are between 60~100 meters. Due to the uplift of the earth's crust and the cutting action of the water flow, a dissolution platform with an area of thousands of square meters and a deep trench with a depth of more than 20 meters were left in the cave. The light in the cave is very dark, the ground is slippery, the temperature is very low, and people shiver with cold, and the narrow dark river swells out unscrupulously in the cave, roaring loudly. The stone walls here have become extremely smooth under the erosion of perennial water, and many rocks have been eroded and precipitated into stalactites. As we come out of the dark and deep caves, you will feel that the scenery here is different in style, each with its own unique characteristics and characteristics. In particular, the first line of heaven that only allows one person to pass through spreads forward, and the canyon with thousands of walls is like an axe and a knife, which is eye-catching. Dense vegetation of all kinds is scattered one after another. Large and small streams flow happily between the cracks in the ground, jumping, rushing, those flowing out like white streams flow freely between the cracks in the ground, making a roaring sound, there is a sound, there is water in the mountains, there are mountains in the water, adding infinite agility. Suddenly, a white waterfall suddenly appeared in front of us. The waterfall pours out from the top of the cliff here, with a drop of 80 meters, and falls onto the dark and smooth rock at the bottom of the opposite cliff, stirring up clouds of water mist and spraying beads and jade.

Then, as the terrain gradually opens up, the colors between the cracks in the ground gradually brighten, and the small streams converge into large streams, and the exit of the canyon is inadvertently reached. Although we were dazzled, overwhelmed, and couldn't take our eyes off it, we couldn't take our eyes off it, but although the scenery here is beautiful, what we were looking for was still not here. We were disappointed to return in vain, and we had to continue to search.
