The entrance was very small, and it seemed to be blocked by sand, and several attendants and some male students began to clean the entrance, and soon, an entrance that allowed one person to enter was cleared.

Li Ling used the instrument to detect the oxygen content inside, and after seeing that the instrument showed that it met the standard, everyone began to bring their carry-on equipment, and the first batch of people to enter were determined, and the expedition foursome went down to two, one was black sunglasses, the other was yellow hair, me, Li Ling, Anna, and three boys and one girl, Liang Qiu was among them.

The rest of the people are now preparing above, and when we determine the situation below, we are here to take them down, after all, I don't know if there will be unknown dangers below, for the sake of safety, we are equipped with radios, as soon as there is a special situation, the people above will immediately come down to rescue.

After seeing the debugging and erection of the radio equipment, Li Ling waved his hand, and the black sunglasses were the first to jump down, not deep below, but more than two meters high.

It appears to be a passage with strange patterns carved on both sides, and Li Ling tells us that this should be a totem, most likely the belief of this tribe.

I also nodded secretly in my heart, this pattern, I have also seen it in the tomb of King Guli, and now, I have begun to slowly determine, this place definitely has a relationship with the country of Guli, all the way to observe and walk, the more spacious it is, Li Ling told me that she learned that this place was walked by the previous expedition team, but according to their records, it will inexplicably go around back when walking here, and they have not really walked into the underground ruins after walking several times, and because of the lack of materials, they had to retreat.

"Walking and walking will come back? What does that mean? ”

Black Sunglasses spoke, he turned around and asked, Li Ling said that she was not very clear, and the notes did not elaborate, after all, it was a foreign expedition team that did not know much about some ancient Chinese cultures, according to what they said at the time, this passage was about 500 meters away, and it would go back inexplicably.

"Ghost hitting the wall?"

Black Sunglasses whispered, but he said again: "No, the ghost hitting the wall is trapped and people are not allowed to come out, and it is a little strange that people will be sent out here." ”

Li Ling also nodded, however, her statement was that this might be a formation similar to the ancient one, which caused people to hallucinate and disturb people's minds unconsciously.

I listened to their speculation, and quickly remembered my own experience, however, I think more, Li Ling's statement should be closer, I believe that it is a kind of formation, soon, we came to a fork in the road, here is a small space, there are some simple murals on all sides of the wall, and some words, it is indeed Guli script, although I don't know Guli script, but I don't know why, I am very sure that these words are Guli script, and the text carriers on them are very similar, What I've encountered is a kind of writing.

Li Ling also told us very sure that this kind of writing is the Guli script, and she has studied the Guli culture more deeply, and I also believe her words, and then they began to record, take pictures, and record.

Soon, everyone began to hesitate which fork to enter, Li Ling told us that at that time, the expedition team entered all three forks in front of them, and finally went back to the origin, that is, here, and finally, they reluctantly walked out from the same way.

Looking at Li Ling's somewhat calm expression, I don't know why she is so calm, does she have a way to crack it, or rather, she is ready to record it here and forget it, obviously impossible, if this is the case, there is no need for such a big battle.

Black Sunglasses said his plan first, he asked us to try these three forks in the road first, anyway, there is no danger of being rounded back, take a walk first, and find the law here.

After all, foreigners don't have a deep understanding of Chinese culture, and maybe we can understand things they don't understand.

There were nine of us in total, divided into three groups, Liang Qiu and I had another group of female students, who chose the entrance on the far left, Black Sunglasses They led a boy to the entrance on the far right, Li Ling and Anna and a male student walked through the middle entrance.

In short, I think this place is very weird, all around is the same as the passage just walked over, the kind of pattern that is exactly the same, the stone bricks under the feet, are all the same style, just keep walking, the road is straight, we don't have any deviation from the direction, there is no turning or anything like that, I am very sure of this, just walking like this, just walking like this, I found that there is a bright light in front of me, I walked a few more paces, and finally, I saw the gas lamp we had placed here.

The three of us stood here for a long time, especially the girl, her name was Yang Xue, and she asked me with some fear:

"Brother Yun, is this place haunted?"

I smiled and comforted her, told her not to think about it, and told her that this is the same as the maze we played when we were children, but, to say so, but even I don't believe what I said, the maze has all kinds of forks in the road, but the road we just walked is a straight road, without any detours, without any forks in the road, just back to the original point, it is really very weird and inexplicable.

It didn't take long for the other entrances to come out of the people, really the other two groups, everyone came out with the same expression as us, you look at me, I look at you, all of them are incredible, only the black sunglasses are very calm looking at the three entrances, in fact, I am very puzzled, this black sunglasses is very interesting, no matter when, he did not take off his pair of sunglasses, it is so dark here, he did not take it off, I am very skeptical, he has an eye disease, dare not let people see.

Li Ling picked up a notebook and flipped through it, and the others also discussed with each other, while I was smoking a cigarette on the side, this kind of brain-consuming thing, I was really too lazy to do it, and when they were discussing it intensely, I saw black sunglasses suddenly rush into the entrance in the middle, and the speed was very fast, and in less than a while, he rushed out again at a very fast speed.

"I just closed my eyes and rushed in, and at the fastest speed, it seems that there are no suggestive objects here that affect people's thinking, and there are no mental obstacles that affect the sense of direction, which is very strange, that is, it is not a hallucination."

Li Ling also explained, and said: "People's sixth sense is completely subconscious, close your eyes, there will be no external interference, this is really strange, not ......!" ”

Speaking of this, Li Ling and the black sunglasses seemed to be flustered, and then the black sunglasses rushed in again, and after a while, he rushed out again, this time, he gasped a little and said: "It's still not right, this time, I even have a closed sense of hearing, and when my hearing and vision are closed, I won't be disturbed by the outside world at all." ”

"Is it smell?"

"No way, there's no other smell here."

Everyone said some of their own ideas, but they were all rejected one by one, until, Liang Qiu, who was beside me, suddenly whispered:

"If we go together, everyone stops at a point, and ...... when they come out?"

Liang Qiu suddenly said an extremely terrifying guess, if according to him, for example, I was the first to leave, then, would I see the back of the last person, then where did I come from? It's a scary guess, but it could be a way to crack the mechanism, and if it's really a Ecstasy or something, it would be pretty clear.

We do it when we think of it, we line up, Li Ling last, I am in the front, Li Ling will stop at the entrance, we walk forward, pause every distance, just like that, I started to walk, soon, I saw the light, however, I didn't see Li Ling's back, at this time, I began to chuckle in my heart, my back was a little cold, where did Li Ling go.

When I walked out, I found that I walked out of the rightmost entrance, and the one I just entered was obviously the leftmost entrance, Li Ling stood at the leftmost entrance and looked at me in surprise, and I also looked at her, and they all began to be silent, and the others all came back after receiving the signal, and when we all got together, everyone was silent.

When I left, there was no fork in the road, it was still a straight line, but why I had another exit, but we all couldn't figure out where I had entered and where I came out before.

Li Ling suddenly said, "Do you know the principle of the Penrose Ladder? It is also what we call the soul ladder. ”
