"Tang Chen, didn't you say that the light in here is very good, why do I feel getting darker and darker?" Zhao Xiaoshi said suddenly.

"Uh...... Well, it's not very dark, can't you still see the road clearly?" Tang Chen touched his nose with some embarrassment. In fact, he also wondered a little, when he came here in his previous life, it was indeed much brighter than this, why is it so much darker now?

Tang Chen raised his head and took a look, and immediately found the problem. It turned out that the small holes on the top of the cave were not as big as those that were opened in the previous life!

In his previous life, when he came here, it was eight years later, and I don't know if the small hole in the roof of the cave was naturally enlarged or artificial. Anyway, it was going to be much brighter at that time!

"Fortunately, you went to buy a flashlight, otherwise, hum~" Zhao Xiaoqian snorted.

"Hehe, I'm very prescient!" Tang Chen's skin was already thicker than the city wall, so he naturally didn't care about her taunt, "Aunt Li, are you okay in the back?"

Tang Chen walked in the front, the two girls were in the middle, and after Li Xiangqin was broken, even if there was no danger here, he still asked.

"It's nothing, what can happen with such a spacious road!" Li Xiangqin replied with a smile.

"That's good!By the way, if we have a fate later, we may encounter a surprise!" Tang Chen began to sell Guan Zi again.

"Hmph, Tang Chen, you are really annoying, every time you are so appetizing!" Zhao Xiaoqian walked behind Tang Chen and directly pinched his waist with her hand. She knew very well that someone would not tell them, and now she said this to whet their appetite.

"Hiss~"

Tang Chen suddenly gasped, and secretly said that this Zhao Xiaoqian was really ruthless! But he still didn't say it, because he wasn't sure if this karst cave in 2005 would be the same as the one eight years later.

Li Xiangqin was curious about the "surprise" Tang Chen said. It will not be easy for him to say this. So what surprises await them at the end of this cave?

With a distance of more than 20 meters, no matter how slow they walked, it didn't take long for them to finish. What appeared in front of them now was a large cave hall that was much different from the one they had seen when they came in.

"This is the surprise you are talking about?" Although there were a lot of strange-shaped stalactites in this cave hall, the people present had not seen them, so they didn't think it was unusual.

"That's not what I'm talking about, you come with me. Tang Chen shook his head and smiled slightly, then beckoned everyone to walk to the cave wall close to the side.

Tang Chen raised his head and glanced at it, then showed a happy smile.

"You guys stand in my place and look up, the surprise is up there!" Tang Chen turned to the three of them and said a word, and then moved to the side.

"It's really fake, it's not fooling us, right?" Zhao Xiaoqian glanced at Tang Chen with suspicious eyes, then stood where he was just now, and raised his head to take a look.

"Wow, that's beautiful!" he looked up, and exclaimed. Zhao Xiaoqian seemed to have seen some incredible beauty, and in addition to excitement on her face at this moment, there was also incredibleness.

"Sister Qian'er, what did you see?" Seeing Zhao Xiaoqian's performance, Zhao Xiaoshi was a little itchy.

"You'll find out if you come and see for yourself!" Zhao Xiaoqian retracted her gaze and moved away with unfinished thinking.

Zhao Xiaoshi stood over, raised her head to look, and suddenly exclaimed: "Wow, it turned out to be a rainbow! It's so beautiful!"

"What?rainbow?!!" Hearing Zhao Xiaoshi's exclamation, Li Xiangqin was stunned. This is a cave, how can a rainbow appear in it?

As we all know, the rainbow is a post-rain optical phenomenon that is formed by reflection and refraction of sunlight hitting rain in the air. You can see a rainbow in this cave, is it raining outside?

Now Li Xiangqin guessed that Zhao Xiaoshi should have seen the rainbow outside from the hole on the top of the cave.

But when Zhao Xiaoshi gave her the position, Li Xiangqin was dumbfounded. What did she see? It was a rainbow across the roof of the cave, about two meters wide.

This phenomenon completely subverted her imagination. Is there such a small rainbow in the world? And it's in a cave!

She looked closely, and saw that there were several places on the roof of the cave where water was dripping, and there was a small stone platform underneath. The temperature inside is very low, and over time, the water vapor will form small droplets on the top of this small hole. Sunlight shines through the small hole above, and if the angle is right, a rainbow is formed.

Theoretically, this condition is indeed capable of forming a rainbow. But rainbows are usually formed in open places, can such a mini rainbow really be formed in such a narrow space?

If the rainbow was really so well formed, I don't know how many such places across the country would have been exposed, but why have I never heard of it?

Looking at Li Xiangqin's dumbfounded appearance, Tang Chen was a little proud. In fact, he walked here for the first time in his previous life, and when he inadvertently looked up and saw it, he was also stunned. Because he had never seen such a small rainbow before, he thought he was hallucinating. But when he pinched himself hard, he found that the rainbow above his head was still there.

He was so excited that he immediately ran over and told his companion who was watching the stalactites on the other side of the cave hall.

The companion said at the time, "Are you sure you are not hallucinating?" Tang Chen saw that he didn't believe it, and he didn't care, so he directly pulled him and ran to that position. But by that time the rainbow had disappeared, so the companion touched his forehead with his hand to see if he had a fever.

The rainbow disappeared, and Tang Chen had nothing to say. He regretted that he hadn't taken the picture at the time, so he waited there for another two hours and still didn't see the rainbow appear, so he thought he was hallucinating. After all, it is impossible for such a small rainbow to appear in the cave.

Although he felt that it was an impossible thing, Tang Chen did not give up, because he knew very well that he had pinched himself at that time, so he firmly believed that it was not an illusion.

So since that day, whenever it's sunny, he'll ride there to see it. Finally, on a drizzly afternoon, he saw the mini rainbow again. At that time, he was very excited, and immediately took out his mobile phone and took a picture of the roof of the cave.

However, because the light in the cave is not good and the distance is a bit far, the shooting effect is not good. No matter how much he adjusts the focus, the shot is blurry. He was using 5s at the time, which was already a good camera, but it didn't work well.

"Could it be that God doesn't allow such a beautiful scenery to leak out?" No one believed that kind of photo at all, so Tang Chen couldn't help but have some thoughts in his heart.

Sure enough, two minutes later, the rainbow faded and then disappeared completely. He didn't tell anyone about this discovery. Because he knows that in order to form a mini rainbow, all kinds of conditions need to be put together. As for wanting to see it, it needs fate even more. Because it's just a flash in the pan, such a short time, if there is no fate, you can't see it.

Later, Tang Chen also went to the other four cave halls to see if there were any similar places. It turned out that there were, but compared with the original place, it was several grades worse.

Even the initial places need various conditions, so these places will naturally not be possible. Sure enough, Tang Chen never saw a mini rainbow again. Neither the original place nor the few places that might have appeared later have been seen again.

After persisting for another month, Tang Chen gave up. Because on several occasions when conditions were sufficient, I didn't see him again. He thinks that maybe his fate with Mini Rainbow is over. Fate is gone, and you can't barely come, right?

In the future, he would often flip through those blurry photos in his mobile phone. Every time he watched it, he would sigh with emotion. During that time, he broke up with Huang Qingya, so he also learned a lot from it. The two of them are just like this mini rainbow that suddenly appeared and disappeared suddenly, they are all fateful, so why bother to worry about it anymore?

Therefore, Tang Chen deleted the photo, and then he gradually stepped out of the shadows. Therefore, the mini rainbow in his previous life was not only a dream in his heart, but also an introduction to wake up.

When he came to Tianyuan Media again this morning, Tang Chen suddenly thought, isn't Xiaonanshan Park right next to it? Thinking of the mini rainbow in his previous life, he was a little excited in his heart, so he brought a group of people here. The purpose is to see if they have the fate to see the mini rainbow that they have only seen twice in their previous lives!

Because in the early hours of this morning, it seems to have rained lightly, and it has only been raining for an hour. In this way, Xiaonanshan will absorb rainwater before seeping into the roof of the cave.

You don't need too much rain, too much water seeps in, and if the water vapor is too strong, it won't form a mini rainbow. That's no more, no less, plus the sun is not very strong today, it should be a good opportunity.

This is all the boredom of his idle life in his previous life, and he ran here to wait for the experience summed up by the mini rainbow!

Sure enough, their fate is very good. In my previous life, I took a lot of effort to meet it twice. The first time I came here in this life, I met it. Could it be because of Zhao Xiaoshi and others?

The wonders of the ages that only he had seen in his previous life, and there were people who witnessed it with him in this life!

"Hey, the rainbow is starting to fade, is it going to disappear?" Li Xiangqin exclaimed.

"Ahh

Li Xiangqin moved his position, and Zhao Xiaoshi and Zhao Xiaoqian squeezed over together. The two are slender, but they can barely watch together.

"It's really going to disappear!Sister Qian'er, hurry up and take out the camera, let's take a picture of it!" Zhao Xiaoshi urged.

"yes, why didn't I think of it!" Zhao Xiaoqian patted her forehead, put down the bag on her back, and began to take the camera from inside.

"Hurry up Sister Qian'er, the rainbow is about to disappear!" Zhao Xiaoshi exclaimed.

"Ah, I haven't turned on the phone yet!" Zhao Xiaoqian was suddenly a little scrambling.

By the time she turned on the camera and pointed the camera at the top of the cave, the rainbow was already faint and almost completely gone.

"Click~Click~" After Zhao Xiaoqian took a few photos, the rainbow disappeared completely.

"How is it, Sister Qian'er?" Zhao Xiaoshi leaned over and asked.

"Alas, the light was not good, and the rainbow became so faint again, and nothing was photographed!" Zhao Xiaoqian was a little dejected.

"Ah, that's a pity!" Zhao Xiaoshi glanced at it, and was also a little depressed.

"It's a pity, let's just wait for it to appear again!, Xiao Chen?" Li Xiangqin suddenly spoke, and then turned his gaze to Tang Chen.

Now she is still a little incredible, how did Tang Chen find out about this? If this phenomenon is exposed, it will cause a sensation in the world again!

Li Xiangqin was sure that in the past, only Tang Chen knew this secret, but now there were three more of them. He was the first to discover this secret, so he must be the secret of the formation of this rainbow. Otherwise, how could they have come here today by such coincidence and saw this almost impossible thing to happen?

The two girls also thought of this, so their eyes lit up again. They turned their gazes to Tang Chen, expecting him to give an answer.

Tang Chen smiled bitterly and said, "I'm sorry, I don't know how to answer this question. Because I don't know when it's going to show up next time, maybe right away, maybe after the next rain, maybe never!"

"What, you can't be joking, are you?" Hearing Tang Chen say this, the two girls couldn't help but be dumbfounded.

"Xiao Chen, what do you mean by this?" Li Xiangqin was also puzzled.

Actually, this is not difficult to understand, you can understand it by thinking about it yourself. This phenomenon is almost impossible, and it can even be said that it violates the laws of nature. If we can see it once, it is already a gift from heaven. If it was so easy to appear, I am afraid that it would have been exposed by others a long time ago, how could it be that no one knew about it until now!" Tang Chen sighed, very emotional. In fact, he feels lucky to be able to see it again now!

"......" Listening to Tang Chen's words, the three of them fell into deep thought. Yes, this is indeed a natural spectacle that defies the laws of nature. They are fortunate enough to see it once, and they are already lucky to have three lives!

"That's true, but haven't you seen it before? Otherwise, you wouldn't have brought us here, would you?" Li Xiangqin was silent for a moment, but couldn't help but ask.

Tang Chen nodded and said, "Yes, didn't I tell you? I was brought here by a partner from Guicheng once before. In fact, I was only in the fifth grade at that time, and my parents took me to a relative's house in Guicheng to play during the summer vacation. Their family lives not far from here, and my older brother, who is a little older than me, brought me here to play. (To be continued.) )
