However, Ning Xiaofan also found that this firefly was much bigger and brighter than the one he had ever seen.

The fireflies I saw before were just a small insect, and then they emitted some bright light, but these are different, each firefly is like a small candle, and it illuminates the surrounding environment, although the range is not large, but because of the sudden increase in the number of fireflies on the top, the cave where the three of them are located is slowly brightened.

"Wow fireflies! so beautiful!" Chang Xiaoxiao also lowered his vigilance after learning about fireflies.

For fireflies, girls like Bai Muxiao and Chang Xiaoxiao still like it very much.

But the biggest utility they bring is that they have a cold and the whole cave is cold.

At this time, most of the cave scene has been illuminated.

The front is indeed a wall, and a very thick one.

"Is this really a wall?" Chang Xiaoxiao suddenly said at this time.

"What do you mean?" Ning Xiaofan looked at her.

"What if this cave is a cave with no exit, it may be that the only exit is the entrance when we came in just now, I think it's possible. Chang smiled and smiled.

"This ......" Ning Xiaofan didn't speak.

"No way, when I came here as a child, there was indeed no wall in front of me, and I'm pretty sure I don't have to deceive you. Bai Muxiao said.

After all, it was Bai Muxiao who led them to this place, and if something happened, it could be said that Bai Muxiao was still responsible.

"Miss Bai, don't get excited, I know you don't have to lie to us, after all, you are also here. I was thinking maybe you were mistaken. We don't have to worry about whether this is a wall or not, we have to think about how to get out, like the hole we came into, can we go out again? As long as the wind outside weakens, we can go out according to the previous hole. Although Chang Xiaoxiao is very afraid of these dark things, he is still relatively organized when he analyzes the problem carefully.

"I think she has a point, we can go back and see what the hole looks like when we come in. Ning Xiaofan said.

At this point, it is not so important to really worry about whether this is a wall or not, what matters is how to get out.

The three of them returned the same way again, but when they returned, they found that the entrance to the cave had been sealed so tightly that there was not even a trace of the entrance.

When the three of them went back to look, they didn't know which direction the hole was heading.

It's incredible.

What kind of cave is this?

Ning Xiaofan felt at this time that this so-called skeleton could be the person who strayed into this cave, and then died here directly because he couldn't get out, this possibility is very big at present.

The three fell silent for a while.

Ning Xiaofan suddenly thought of his perspective function, since the golden cicada recovered, he seemed to have recovered his perspective, if he could use his perspective to help him get out of here, it would be excellent.

Thinking about it, he directly opened his perspective.

But he was a little disappointed.

Perspective worked, but when they entered, the hole in the place was nowhere to be found.

As if there was no opening, it merged with the wall next to it, and there was no trace of it at all.

However, Ning Xiaofan saw the switch, which was the switch to turn on this cave.

But the switch was only placed outside the cave, that is, on the ground, and not in the cave.

In other words, it was almost impossible for them to get out of the hole again.

Then they came to the spot where there were fireflies again.

Just when the two of them felt hopeless, and they both felt that they were going to die here like that skeleton, Ning Xiaofan was suddenly surprised to find that the wall in front of them that was blocking them from moving forward was indeed a wall.

Behind this wall is a tunnel with a staircase.

This shows one thing, that is, Bai Muxiao said before that when she came when she was a child, there was a tunnel in front of her, and she went down from the tunnel and then went directly to the outside of Lingshan, which is very possible. And the existence of that skeleton shows that there were indeed people who came to this cave during the time when Bai Muxiao didn't come later, but because of the existence of this wall, he didn't go out, but was trapped and died here.

But the question is, why is there such a wall all of a sudden?

What is the reason for the existence of this wall?

This thing is hard to imagine, Ning Xiaofan thought about it for a long time, but he didn't come up with it.

"Are we really going to die here?" Bai Muxiao said.

The others didn't speak, but it was obvious that except for Ning Xiaofan, Chang Xiaoxiao was now also in a very sad atmosphere.

After all, this kind of thing is very uncomfortable for anyone.

"I'm sorry ......"

Bai Muxiao said suddenly.

Obviously, Bai Muxiao feels that this responsibility lies with himself.

"Don't you be so pessimistic? Who said we have to die here now? Ning Xiaofan naturally knew that it was indeed just a wall, as long as this wall was opened, there was a possibility of escape.

Of course, Bai Muxiao and Chang Xiaoxiao naturally didn't know, and it was because they didn't know, so they were a little sad now.

"Can't get out, judging from the current situation, we are almost blocked here, this skeleton should be the one who entered this cave and couldn't escape, and our fate should be the same as him in the future. Alas. Chang Xiaoxiao sighed, and she could see that she was very helpless and regretful.

Bai Muxiao said: "I'm sorry for you, if it weren't for me, you wouldn't have entered this place at all." It's my responsibility, and you kill me now, and I have no complaints. ”

Ning Xiaofan didn't expect Bai Muxiao to be able to say such a thing, which really surprised him.

"Alright, you guys take care of it, I can tell you clearly, now we just need to open this wall and we can escape. Ning Xiaofan looked at them and said.

"Wall, you say this is a wall?" Chang Xiaoxiao suddenly looked at Ning Xiaofan, he knew that Ning Xiaofan's skills were still relatively large, after all, the person who could exorcise ghosts for himself was definitely not ordinary, and he was not a liar, he had that kind of real ability.

"yes, it's the wall. After Ning Xiaofan finished speaking, he knocked on the wall in front of them.

It's just that the walls don't make a crisp sound, but it's not stuffy either.

It is precisely because there is no crisp sound, so they often smile and feel that Ning Xiaofan is comforting them, if this is really a wall, then knocking on the wall will definitely make a crisp sound, but at present, there is no, that means that this is not a simple wall, but a solid mountain.
