However, Gu Chen's incomprehension made explorer Xu Enping unable to answer for a while.

Because this is a very real issue. When exploring a cave, you must at least leave a mark, right? This is basic common sense.

Since both of them are experienced guides, how could they not be clear about it?

So Gu Chen's question made Xu Enping a little embarrassed.

However, Gu Chen asked and answered himself: "Maybe there is another possibility."

"What's possible?" Seeing this, Xu Enping quickly came over and asked.

So Gu Chen quickly replied: "That's this group of people. Maybe they have been here at some time before."

"Moreover, they may have been here to explore the cave a long time ago, so they know the situation here very well and know what the structure inside is like."

After a pause, Gu Chen continued: "For example, they know that they can reach this open area by walking straight from the entrance of the cave."

"But if they want to go from here to the next location, they have to mark it accordingly."

It seemed eerily quiet outside, with only the sound of Xiaojia talking and some walking noises.

"Look at that." Yuan Shasha pointed to one of the walls.

"Officer Gu, do you think you can continue to go like this?"

That is not only for Hou Qinsheng to listen to, but also for others to listen to.

When I was young, Xiaojia came to an area with cracks.

It can make a senior outdoor explorer feel scared, Gu Chenneng'er, the road ahead will be less dangerous.

And that outside corresponds to a cave.

You can't tell from the movement. The water drop in the river outside is very small, so the movement of the water hitting the rocks will be very obvious.

"Once he falls from those cracks, there is no way he can be rescued. He will be washed deeper into the ground by the underground river."

"Yeah." Xu Enping agreed in a complex voice, feeling that at this moment, he really couldn't be too slow and should be calm and calm.

It was not really stupid to choose to be alone at that time.

Moreover, there were bad marks along the way. If he was afraid, he could actually follow the marks and get out of the cave by himself.

"Well, what you said makes sense." Seeing what Gu Chen said, Xu Enping also agreed with this statement.

Gu Chen explored the path behind, but also found that the passage of the cave seemed to be getting wider and wider at the end, which was very different from the terrain that Xiaojia passed through just now.

Subsequently, Hou Qin walked to Xu En's plane and asked: "Senior Sister Lu, it's probably not a long distance for you to retreat into the cave?"

"Yes...yeah." The person who answered was another young guide. That guide seemed to be at the level of a rookie. He was not the kind who only dared to stand in the cave, take photos, and then post them on Moments.

level.

"There is no sound of dripping water." Gu Chen, who has no observation skills at the level of a junior master, has not heard any sound of dripping water.

But now we have only retreated a few hundred meters into the cave, and no two people in the team are making any progress.

"They are all located in deep mountains and old forests. No terrain is possible. There are very few places where the locals themselves dare to go there." Lu Weiwei also explained.

"Then if it falls, it will still be black and blue?"

"Officer Gu, I'm afraid he will laugh." Seeing what Hou Qin said, Lu Weiwei also communicated frankly and explained:

"That time I came here, it wasn't very difficult to get out there, but you didn't notice these two guides."

"With so few of you together, what are you afraid of? How can you be a household guide if you are afraid? First of all, courage means qualification."

That's why Lu Weiweinenger was asked to re-evaluate whether she needed to continue to retreat.

So Lu Weiwei quickly comforted her and said: "I have seen that kind of big scene several times during the subsequent caving. Can it be a long and narrow passage?"

"Senior Brother Gu, you seem to have discovered the mark."

When Xiaojia came to a slightly narrower place, Gu Chen signaled that Xiaojia could not take a short rest.

Moreover, the situation in the cave is complicated, and all kinds of strange-shaped stones actually look similar, making it difficult to rely on any one as a target.

Gu Chen didn't have any worries in that regard. He thought that the two guides had retreated into the outside before. It was not a big problem for him to retreat into the outside. He just had to be less careful.

When they got there, Gu Chen couldn't hear clearly, and there was no sign of the river flowing.

Especially mysterious caves, in fact, have no natural appeal to explorers.

"You have been to few places to explore, and you have met few safe and bad friends. You died on the way to explore."

The water that fell up formed a high-lying pool in those high-lying areas.

Because Gu Chen hadn't felt it clearly yet, as Xiaojia went deeper into the cave, the feeling of fear continued to spread.

Looking around, Gu Chen reminded him, "Everyone, try hard to search. They will definitely leave a mark in the cave."

Just like that, Xiaojia climbed up the steps of the cave to a spacious area. At that time, Xiaojia discovered that what appeared behind Xiaojia was a long and narrow walkway, and the rock wall at the top of the narrow area was very low.

"They see that the two older girls are scared. Do they think the two girls are the same?"

"Officer Gu, that place is really weird. You don't think it's safe to retreat."

At this time, Yuan Shasha shouted, instantly breaking the tranquility in the cave:

If others don't gather together, maybe the mysterious creatures in the cave will still touch him.

"It's mainly because it's your first time in a dark and white place. To be honest, you really are not mentally prepared."

Gu Chen even heard a few other young guides here whispering to each other, and seemed to have given up any intention of making an impact.

The reason why I didn’t retreat from the hole next time was because I didn’t bring professional tools.

But the more extremely quiet the environment, the more it makes people feel peaceful and scared.

But what's even worse is the lack of one more reason to retreat.

Apart from that, Hou Qinsheng still forgot to compare Xu Enping and Yuan Shasha:

"Now it seems that it is far away from the underground river on the ground, but I must pay attention to it. Places without underground rivers are often very safe."

This chapter is not over yet, please click on the next page to continue reading! "According to your youth caving experience, you have not yet come to the underground river area and discovered the underground river in the cave, or it flows through the cracks in the ground.

Passed, and the movement was still very small.”

Outside is a step-shaped corridor that extends all the way down.

But in that mysterious, unexplored cave, what is most lacking is not certainty.

Especially in the dark, that sense of fear will be minimized.

"That's right." When Hou Qinsheng said this, one of the young guides didn't seem a little embarrassed and quickly defended himself:

After all, at that time, if he wanted to make a mark, this person, Neng'er, would go back with him.

"Everyone has no problem, so you can continue walking. You are the first one, and Xiaojia will follow."

"Senior Sister Lu, please be patient. Find her quickly." Seeing that Xu Enping was not impatient, Gu Chen quickly comforted her.

"Young man, you fear life more because you understand the power of nature."

Moreover, perhaps only the two pioneer guides knew about that mark.

What if we want to continue walking back? It seems that this will make Lu Weiwei less shaken.

"It's an underground river on the ground." Officer Wang shined a flashlight on it and complained:

But only one person can leave at a time.

As Xiaojia continued to walk back, the sound of running water stopped and became louder and louder.

Before the water in the pool overflows, it flows straight along the high areas.

After a pause, the young guide looked at Xu Enping again and said quickly: "It's true that both of us girls are afraid. What are you young gentlemen afraid of? It's just the long and narrow passage."

When he discovered the unknown crack in the cave, Hou Qinsheng's heart went up and down, feeling uncertain.

"It's just a matter of time and again." Xu Enping said.

In fact, saying that is out of necessity.

…

Gu Chen also sighed with emotion: "I really thought that there wouldn't be such a deep and long cave in that place."

After all, it is really difficult to find a certain mark in the white cave.

"Mr. Xu, Mr. Xu?" Seeing Lu Weiwei standing there in a daze, Hou Qin also reminded him.

Xiaojia then discovered that it was a white mark.

Perhaps people who often explore have seen too few safe terrains, so they cherish their lives even more.

This kind of panic will continue to spread to the entire team. By then, everyone will be able to do it and will be able to play well.

"Wrong." Lu Weiwei was also excited and quickly reminded:

If they really retreated into the cave to explore, it seems that the two of them didn't have enough courage.

Just like that, Xiaojia kept changing his walking posture, retreating deeper into the cave bit by bit.
