Deep underground, the vision is like a fairy mirror, looking at it from a distance, it seems that there is a faint rainbow above the clouds, leading to the platform at the foot, everyone can't help but stretch out their hands, and touch the rainbow, as if the rainbow is tangible and qualitative, only after grabbing the void, everyone can't help but smile!

Wang Weihan couldn't help but admire:

"I didn't expect that there was such an underground world of the Wonderland Race under the Tianjin Wei Underground!"

Han Dada'er, Mei Ruohong and others were also impressed by the vision and praised one after another.

At this time, although I am thousands of meters underground, it is humid and warm, and the air flow is smooth, and there is a gentle breeze and bird songs. The stalagmites loom high overhead, but beyond that, there is a bright light, illuminating the entire underground world as if it were day!

There are two stone pillars on the edge of the platform, on which are also fastened with broken iron cables. Four iron cables were mottled and hung from the cliff at the edge of the platform, and a few rotten planks hung from them. Hundreds of meters away from the platform, above the clouds, there seemed to be something towering above the clouds, that thing seemed to be a platform, there were two pillars on the platform, and there seemed to be one or two iron cables hanging on the pillars. It's just that it's too far away, and the clouds and fog reflect the white light and it's really hard to see.

Han Daring said:

"I think it was a ropeway bridge that led to the other side. It's just that the iron chain has been rusted and broken for a long time, and it can no longer be passed.

Everyone also knows that this platform is not a place to stay for a long time, and if you want to find a way out, you can only hang down the rope and climb the rock wall and go down. However, the lower part was shrouded in clouds, and I didn't know how high the platform was from the ground, and whether the rope on my body was long enough.

Everyone looked down at the platform. Under this platform, the mountain wall extends downward, and then down is a pitch-black mass, because the lower part of the mountain wall is somewhat concave, and dozens of meters away from the mountain wall is a gradually thick cloud and mist, so you can only see the bottom of the mountain wall, and then the distance is not clear at all.

At this time, Chen Feiyang pointed to the edge of the platform and said excitedly:

"Master! Look! ”

Before he could finish speaking, his feet slipped, and his body fell towards the bottom of the platform cliff. Fortunately, Han Daring was by his side, and he reacted very quickly and pulled Chen Feiyang back to the edge of the cliff.

Han Da'er sighed and said:

"Death! Be careful! ”

Chen Feiyang was also frightened into a cold sweat, and he couldn't speak for a long time. After the shock calmed down for a while, he pointed to the edge of the cliff and said:

"Master! Look! There's a rope that hangs down! ”

When Han Daring pulled Chen Feiyang back, he had already seen the pitons nailed into the stone on the edge of the cliff, and the pitons were still tied with ropes. This rope is the same as the rope used by the people who came down first when entering the ground from the temple.

Han Daring was worried that the other party was using his hands and feet on the rope again, so he took out a short shovel and slowly picked up the rope, and found that there was no iron needle on the rope this time. While pulling the rope up, he calculated the length, and pulled the rope for hundreds of meters until he saw the end of the rope.

Mei Ruohong said on the side:

"It seems that this platform should not be more than one hundred and twenty meters away from below! To be on the safe side, let's use the rope we bring safer! ”

Han Dada'er also had this intention, so he asked everyone to rest on the platform for a while, and he found a few rock wedges, found another position, fixed all the rock wedges, and then untied the rope and tied the rope end to the rock wedge.

At this time, he turned around and looked towards the doorway that came out, and saw a rock wall rising from the sky, leading to the top of the cave in this underground space, and looking up, the platform was at least two or three hundred meters high from the top of the cave.

The roof of the cave was filled with white glowing hedron floating gas, and those gases emitted white halos that swirled around the roof of the cave.

Mei Ruohong looked at the roof of the cave and said:

"Those should be phosphorescent gases, plus the fluorite on the roof of the cave, illuminate the entire underground as if it were daylight!"

At this moment, an extremely strong gust of wind suddenly blew from a distance, and the wind was unusually cold, breaking through the layers of clouds and mist below in an instant. The strong wind blew and blew everyone's clothes and hair scattered, and raised a lot of dust.

The place where the gale reached seemed to be only a few dozen meters above the platform, and the phosphorescent gas on the top of the cave was disturbed and immediately dispersed, and the entire underground world instantly became much darker, and after a short time, these phosphorescent gases converged again, still quietly circling the spar on the top of the cave, and continued to emit bright and soft light.

Suddenly, the rock wall behind everyone let out a strange howl, whimpering and crying wolf, and the sound echoed around the platform, as if the entire rock wall was howling from top to bottom.

Only then did Han Da'er realize that there were countless holes, large and small, scattered throughout the rock wall. It is the wind that hovers high and blows into the hole, flies and accumulates in the hole, and then passes through the hole in the rock wall to continuously pressurize, and finally injects into the stone chamber excavated in the wall, and then sprays out through the giant urn.

Han Daring told everyone about the discovery, and then said:

"I think the ancients must have used the terrain here to build stone chambers and large urns, which gave rise to this magical slow-falling effect like a windpipe.

At this time, taking advantage of the strong wind blowing away the clouds below, Han Daring looked into the distance.

I saw that the space under the platform was wide and vast, and the ground directly below was full of black soil, and tall stalagmites stood everywhere, and the black soil range of this stalagmite was about one or two miles wide. Beyond the stalagmites is a huge stone forest, the boulders are stacked on top of each other, stretching endlessly, although it does not look as high as the platform where everyone is located, but at first glance it seems to be at least dozens of meters.

This stone forest is like a reverse bow, facing the stalagmite black soil. It was like a stone wall, isolating the black earth, but it was very wide, but it was several miles wide.

Looking further away, a large area of crystal light converged together, constantly undulating and drifting, and it turned out to be an underground river, which was dozens of meters wide from the point where we stood.

At this time, the clouds that had been blown away by the strong wind were gathering again, enveloping all the space in the distance. The clouds and mist are ethereal, and the scenery in the fog only appears and disappears from time to time, only to feel that there seems to be a huge scene, wrapped in it, but from here it is always impossible to see what it looks like, only to feel that the scenery is unusually wide and majestic.

Everyone saw that the clouds were gathering again, and they couldn't see the scene under the clouds clearly, but they couldn't help but look towards the sea of clouds again, after all, this scene like a heavenly fairy mirror was only seen in the book, and a few people could witness it with their own eyes.

Everyone drank some water, ate some dry food, and then sorted out their equipment. Most of the food in Fan Tong's backpack had been killed by him, and the vacated space was stuffed with a lot of utensils that he had just picked up, in addition to the humanoid bronze lamp, there were also many oxidized and blackened gold and silver utensils, which were heavier to carry than before.

Han Dada'er said to Mei Ruohong:

"We're underground, but there's a lot of air, there's plenty of oxygen, and there's a lot of wind, and I'm not a scientist, so I don't know if it's normal."

Mei Ruohong thought for a while and said:

"The air pressure here is relatively stable, and when the fog cleared a little earlier, I saw a big river. It may have its own ecosystem, or it may have algae and plants that produce oxygen.

As for those strong winds, they should be similar to the winds that form on the surface.

It's so big here, and there are a lot of plants and birds underneath, so the temperature should be quite warm. At the top of the cave, there is no vegetation and the temperature may be relatively cold.

When the hot air on the ground rises, the cold air at a low temperature at the top flows horizontally, and the rising air cools down as it cools and becomes heavier, and the air heats up again because the temperature below is high, and the wind is generated by the flow of this air. ”

Ye Ling exclaimed on the side:

"Sister Mei, you know so much! Really knowledgeable! ”

After Ye Ling finished speaking, an unknown insect suddenly landed on her shoulder. The insect has a pair of membranous wings, and its wings and body glow brightly blue. The surface of the insect is shiny and shiny, and it seems to have a thin carapace.

Ye Ling was not like a different girl, she was disgusted and scared when she saw the insect, and she was about to reach out and pinch the winged worm. Suddenly, a gust of wind swept by, and in the wind, a small shadow also quickly crossed it, but it was a small bird.

Like a swallow picking up water, the little bird swept over Ye Ling's shoulder, swallowed the blue insect into its stomach in one bite, flew upward, and then drew an arc in the air, circled slightly, and landed on the edge of the platform.

Ye Ling said in surprise:

"This bird has four wings!"

When everyone looked at it, they saw that under the two big wings of this little bird, there were two small wings, and it turned out to be really four wings. I saw that the bird's eyes were as bright as gems, and when I saw Ye Ling looking at it, it flew into the air, staring at Ye Ling and hovering. It was only slightly larger than a silver dollar, and sometimes it flew up and down, sometimes hovering in mid-air, and moved like a hummingbird.

Mei Ruohong and Ye Ling were also surprised to see this little bird, Chen Feiyang took a few steps closer to the little bird, wanting to reach out to catch it, the little bird was frightened and immediately flew away, but it still stayed nearby, obviously very curious about this group of people.

The bird circled for a while, flew towards Mei Ruohong, circled around Mei Ruohong for a while, and then flew towards Wang Weihan, as if he was not afraid of people.

Wang Weihan was also amazed and said:

"This ...... This seems to be the bird mentioned in the "Classic of Mountains and Seas", and it seems to be called "hustle"! Eating the meat of this bird can detoxify and relieve abdominal pain. But it seems to be different, although the hustle has four wings, but only one eye! ”

Fan Tong said excitedly:

"Can this bird detoxify? If we catch two of them, we can take these birds out and make a fortune! Even if it is sold to pharmacies, the price is estimated to be low! ”

Chen Feiyang said:

"You're out of the money! Stealing those objects just now isn't enough! ”

Fan Tongyi said angrily:

"You don't talk nonsense, why don't you steal, don't throw that thing on the ground, I'm calling it pickup! What's wrong with your greed? ”

At this time, the noisy bird flew back again, and Fan Tong wanted to reach out to catch it, but before he could get close, the bird quickly ran away again. Fan Tong's foothold was unstable and he almost fell off the platform, but Li Huan was quick and pulled him back.

Li Huan didn't like to say much, and he couldn't hold back at this time, and said to Fan Tong:

"You can stop!"

Han Daring approached the bird again, wanting to observe it for himself, but the bird thought that Han Daring wanted to catch it, so he fled away.

Han Daring said:

"If you look closely, in fact, the bird does not have four wings, but the wings of this bird are a little strange, and when the wings are shortened to the end, it suddenly gives birth to a few more long feathers, and the color is darker than the double wings, so it looks as if there are two small wings under the big wings!"

When everyone heard this, they wanted to take a closer look, but the bird had already flown far away.

Mei Ruohong Road:

"Although this bird seems to be not afraid of people, it is very alert, and the biological habits of nature are formed through long-term evolution. It's a deserted place, and this hustle and bustle is so alert, there must be some other threat. ”

In fact, Han Da'er also faintly felt this way, this is like a fairyland's underground world, maybe there is a huge danger lurking, waiting for his group of people to step into the trap step by step.

Just as everyone was getting ready, no one noticed that the bird was on the edge of the clouds, trying to fly into the clouds when the gale rose again. But before the clouds and mist could disperse a little, suddenly a shadow of the fog came, and the noisy bird was instantly dragged into the fog and disappeared.

After resting on the platform, everyone finally made up their minds to go down and find out. Han Da'er checked the rock wedge and the tied rope again, tied a thin rope, and then took the lead to climb down the platform.

He agreed with the others that there would be no danger on the ground, so he would pull the rope, and then the others would climb down the rope one by one.

Han Daring'er himself is strong in martial arts, in addition to having ropes to borrow strength, he also borrowed a little bit of strength on the rock wall, and at a height of more than 100 meters, he landed in a few clicks.

The place where you landed was soft, and when you looked down, it was all soft black dirt. The soil was soft and contained many shiny stars, like a large number of shards of glass or precious stones. Not far away, there are several tall stalagmites, the slightly white stalagmites with the black soil all over the ground, it looks very strange.

Not far away, the group of people who came down in front of them left a lot of footprints on the black dirt where the rope was hanging, and it seemed that there were eight or nine people. The footprints went towards the depths of the stalagmites, which should have been left by the group in front.

He looked around again, and the towering stone pillars and stalagmites were scattered and layered, covering the distant scenery from the wind and rain.

Han Daring pulled the string, and after a while, Mei Ruohong slipped off the rope first.

As soon as she landed, she looked at the rock wall above and said:

"I looked at the rock wall along the way, and I found that there were a lot of hedron minerals on the wall, which should be a type of magmatic rock.

As far as I know, these rocks are formed after the cooling of volcanic magma eruptions, and because they condense deep underground, a large number of crystals are formed. The magmatic rocks on the surface condense much faster than underground, and it is unknown how many tens of thousands of years it would take to form such a huge rock wall. ”

Han Daring said:

"It's not surprising to see this underground world now!"

Not long after, Ye Ling Wang Weihan arrived one after another, Chen Feiyang also arrived after a while, only Fan Tong wasted half a day's work, and only rubbed it down little by little, and thanks to Li Huan's help all the way, he stumbled and fell to the ground, and after Fan Tong came down, Li Huan also followed.

Everyone stepped on the soft black soil, looking around, although the clouds on it did not disperse for a long time, but the light on the top of the cave shone down, shining on the clouds, reflecting a white light, although not as bright as on the clouds, but not dim, but a little like a false cloudy race, the light is slightly insufficient.

Suddenly, out of nowhere, a foul smell came out.

Chen Feiyang covered his nose and said:

"Old Fan, did you fart!"

"You're farting!"

Fan Tong retorted, but then he also smelled the stench, and immediately reached out to cover his mouth and nose.

Everyone felt that this stench was choking, and there was a strong smell of blood in it, and after careful identification, they found that this smell came from the black soil under their feet!
