"I didn't expect to accidentally fall into this underground and actually see this kind of peerless spectacle that can only be seen in movies. ”

After looking at it sluggishly for a while, Su Yan gradually came back to his senses and began to check the surrounding environment a little sluggishly.

The place where he was now was a huge underground stalactite grotto, and a small river that meandered through the ground not far away.

The water of the river is crystal clear, even if the light in the cave is not strong, Su Yan can see the fish swimming in it.

After not finding anything else in the cave and being safe, Su Yan looked at the barrage in the live broadcast room.

Seeing the various shocking statements expressed by the audience in the barrage, Su Yan didn't think they were too exaggerated.

This kind of amazing place hidden under the deep mountains is unavoidable, and it is a blessing to see it.

Regarding the barrage where some viewers in the live broadcast room asked him why the stalactites here glowed, Su Yan did not answer immediately.

He first judged the direction of the exit of this grotto, and then said as he walked towards what felt like the exit:

"I've seen some viewers say they've traveled to places where there are stalactite grottoes, and some of the stalactites in those landscapes emit all kinds of fantastic colors when illuminated by the lights!"

Seeing the various "111s" that expressed their approval constantly floating in the barrage, Su Yan continued:

"In fact, stalactites are formed by the continuous deposition of calcium carbonate and other minerals. ”

"Viewers who have studied chemistry should know that calcium carbonate is decomposed by water containing carbon dioxide to form a calcium bicarbonate solution, when this solution flows down the rock, it will come into contact with the air, and then his chemical reaction will be reversed, and it will be converted into calcium carbonate and solidified on the rock. ”

"These calcium carbonates slowly increase over the years to form stalagmites that look like they're growing from the top, which is how stalactites are formed. ”

"And the stalactites of all colors that you see in other scenic areas are in the process of calcium carbonate solidifying, and other minerals are entrained in them. Different minerals will have different colors, and the common ones are some colors that cannot automatically emit light, so these scenic spots need to use various lights to reflect the color of stalactites to attract more audiences. ”

As he spoke, he looked at the stalactites above his head that constantly emitted starlight, "As for why the stalactites in this grotto automatically emit this starlight in the dark, it should also contain some kind of mineral that will glow." ”

At this time, he turned his head to look at the camera and smiled: "As for what kind of mineral, then I don't know, after all, I'm just an outdoor anchor, and I don't understand a lot of things." Leave it to the mineralogy professionals to identify. ”

"I like the way you don't understand and admit it. ”

"On the top floor, those anchors who don't understand and pretend to know everything are really disgusting, or watching Huo Ye's live broadcast is wonderful. ”

"Huo Ye knows enough things, and it's not a big deal if there are a few things he doesn't understand. ”

"God is Almighty, and man is man. ”

Su Yan thought that he said that he didn't know what minerals were contained in stalactites, and the audience would ridicule him, but he didn't expect to support him so much.

It seems that he already has a certain weight in the hearts of these audiences. ”

Not continuing the topic, when he went into the cave to check on the situation, the time should have been around three o'clock.

Then, after a series of encounters in the cave, it is estimated that another half hour or so has passed.

That is, before dark, he had less than three hours to get out of here, and to find food and a place to spend the night.

In this way, his time is already relatively short.

"Let's keep walking ahead and see if we can find a way out, or I'll have to go back to the stone house where I fell and climb up the slope hole. ”

Su Yan said something to the camera, and began to speed up and walk forward.

This grotto was really big enough, and he walked forward for about four or five hundred meters, before he finally saw a glimmer of light from the starlight in the cave.

He pointed the camera at the place where the light appeared, and said excitedly: "You see, there is a ray of the sun in front of you, and it should be the exit of the grotto, let's hurry over." ”

Although the floor of the stalactite grotto was not very flat, it was much easier to walk than the road in the forest, and he came to the exit of the grotto in less than five minutes.

It's just that when he arrived at this exit, Su Yan found that he couldn't get out.

The position he was in was still underground, and the ground was about twenty meters high from him.

And the opening above is an irregular small circle, while the area below is getting larger and larger, like a super-large round table space.

A small river in the grotto comes here, forming a small pool.

Although the water is clear, you can't see the bottom of the pool.

And the water of the small river continues to flow into this small pool, but the water level of this pool is not seen.

Su Yan knew that this situation meant that there was an underground river or a channel connecting to the outside river under this small pool.

Through the rotation of the camera, the viewer in front of the screen can also see the hole.

"NO, Huo Ye is going to be trapped in this Starlight Grotto?"

"Hey, Starlight Grotto, that's a good name. ”

"Damn, is it a good time to pay attention to the name of the grotto?"

"Oh...... That's right, then how is Huo Ye going out now? ”

"I can't get out, unless a long rope is thrown down from the ground and let Huo Ye climb up along the rope, otherwise I can only fly out......"

Su Yan glanced at the barrage and agreed very much.

This kind of round platform space, not to mention that his climbing skills are only beginner, even if it is a full level, it is estimated that he will not be able to climb it with his bare hands.

Unless he can cling to a wall on all fours like a gecko.

"Do you really have to go back the way you came?"

Su Yan reluctantly took a closer look at the situation at the bottom of the cave.

The space at the bottom of this pit is still quite large, and it is roughly estimated that the diameter should be more than 30 meters.

"Hey, you see, there's a piece of bamboo growing on the other side of the pool, which is a good thing. ”

Seeing that there was actually a small bamboo forest growing in a corner on the other side of Xiaotan, this made Su Yan's originally somewhat lost mood instantly feel a lot better.

Su Yan smiled and said to the camera: "Originally, I had planned to return the same way. ”

"Although tossing back like this will not only consume my remaining physical strength. And it was past four o'clock, and when the time came, I still had to drag my tired body to find food and shelter immediately. ”

As he spoke, he touched his wet clothes, "But these are better than staying here overnight!"

"Although it seems safe enough to camp out tonight, without the bamboo, there would be no materials for this underground grotto to make a fire. ”

"And bamboo does more than just make a fire. ”
