Everyone turned to walk back, and this time for a long time, the petroglyphs that should have appeared, and the holes with ropes hanging from them did not appear. We were all on the same dark road in front of and behind, and there was no end in sight when the flashlight shone past. Tension began to spread.

"My day! I'm afraid it's hell, right? The scholar's words made everyone even more nervous. This place is so strange and pitch black, even the originally bold people can't help but break out in a cold sweat when they mention the word "ghost".

"I didn't find a fork in the road at all, and I didn't find the end to explain it just now. Now that I have returned the same way, I have walked for so long, why haven't I returned to the same place? Could it be that you have encountered a ghost hitting the wall? "I'm starting to get a little scared, too.

"No, it won't. Ghost hitting the wall is generally a trick and you have to use a lot of references. This place is a road, and there is no special object to use as a reference to confuse people, how can you get out of the ghost and hit the wall? It seems that there is some other mechanism. The fourth master said.

"Let's do this, make a mark. Draw a circle on the wall at intervals, and if that doesn't work, press the mark back. Lao Xu proposed.

They decided to keep walking in the direction of the mural, drawing stones on the wall as they went. After walking like this for a long time, it still didn't come to the end, and everyone's sense of fear became stronger and stronger, and they couldn't help but go faster and faster, and finally they even began to trot. But nightmares don't wake up from fear, and there is still no mural in front of them, and there is still no hole with a rope hanging down. Under the effect of fear, physical strength dropped very much. We had to decide to take a break, drink some water, eat some compressed biscuits, and replenish our energy. The scholar looked forward to the wall while eating, and suddenly found that a large circle appeared on the wall not far from us.

This is the circle that we decided to mark at the beginning, and the scholar smiled at the time and said that this is the starting point, and the bigger picture is imposing... Looking at it now, the scholar's face was even more ugly than crying, and he still had a biscuit stuffed in his mouth, but he was surprised that he had forgotten to chew. We couldn't eat anything anymore and ran over to stare at the circle.

"We're back to square one?! What the hell is this! It was obviously difficult for scholars to accept this fact.

In fact, to be precise, it is back to the beginning. Relative to this starting point, I still want to go back to square one. If I knew it was so weird, I wouldn't have come down from the inner hole if I was killed. The big circle at the beginning stared at us mockingly like an eye. The fourth master seemed to be surprised for a moment, and immediately recovered his indifferent demeanor, "There are no ghosts here, it is your own heart that has ghosts." Something must have confused us. ”

But how is it possible to walk back to square one from a straight passage with no forks in the road? Everyone doesn't know. Later, Lao Xu came up with a solution, that is, the four of them were divided into two groups and went in reverse. Any group that finds an anomaly or finds the origin blows the whistle we bring for help in the wild. I was originally opposed to dispersing and weakening the force in this situation, but I couldn't think of any other good way, so I had to adopt Lao Xu's suggestion. In the end, it was decided that I would be in a group with scholars, and Lao Xu and Siye would be in a group. Our group continued to move forward, and Lao Xu and Si Ye went back in reverse, and everyone agreed that if nothing was found for more than an hour, they would go back the same way and return to the mark of this big ring.

After the soldiers split into two ways, the scholar and I walked hand in hand, checking the marks on the wall as we walked. It is a sign that has indeed made what we had carved on the wall appear so suddenly that it is difficult to understand what is really going on. Now, instead of thinking nonsense, it is better to step up and explore as far forward as possible, and maybe you can find the starting point. But Murphy's Law does exist: the more fearful you are, the more you will eventually appear.

I walked with the scholar for a while, and I noticed a bright light in the distance! On this dark road, there is a light in front of you, which makes people nervous. The scholar and I turned off our flashlights, held our breath, and walked slowly forward to see what the light was coming from. As a result, when I got closer, it was actually the flashlight of the fourth master and Lao Xu! The scholar and I turned on the flashlight, and apparently the other party was also shocked.

"Xia Nan? Scholar? Lao Xu was more than ten meters away from us, asking tentatively.

"My day! Fuck me! "The scholar and I were obviously stunned as well.

"Is it really you? Why are you running ahead of us?! Lao Xu asked.

"I want to ask you how you got ahead of us." The scholar's face became even more ugly.

Then everyone realized that this road was actually a ring! We walked in the opposite direction, exactly in a circle. But the road has always been straight, and there is no fork in the road, how can we walk all the time? And even if it's a ring, then why can't you see the original fresco and the rope of origin?

"I knew this was the case, so I bought some paper money in advance. It must have been the trick that the ghost in white had tricked us. As soon as I got out of the cave, I found a ghost, and you don't have to say that I was dazzled. What now? The most important thing is that he hasn't married a daughter-in-law yet, and he doesn't want to die in such a ghost place. "The scholar chattered, and he didn't have his usual demeanor at all.

"Don't panic, everyone, it seems that you are on the way. It's definitely a trap here. As long as you figure out how the mechanism works, you can get out. "The fourth master keeps cheering everyone up.

"Lao Xu, you're just doing archaeology, and you've encountered a lot of ancient tomb organs, right? What do you think is the principle of this mechanism we encountered? "I think it's useless to panic now, it's better to calm down and think about the key.

"Many ancient tombs do have anti-theft devices such as quicksand machines and crossbows, but I really don't know that a single road like this can trap people. But I have a feeling that something is wrong with our senses. Lao Xu said.

"Lao Xu is right, there is no Dao technique that can distort space, so that a road can be connected in the first place, it only means that the road itself is a loop." The fourth master appreciated Lao Xu's calmness, "This road should be a loop, but due to the darkness around it, the ups and downs on the Yong Road, and the walls are exactly the same, it is easy for people to lose their sense of direction." In the absence of a reference to correct the direction of travel, because the right foot is more powerful than the left foot, the right leg will be slightly larger than the left leg, and the distance will be long, and we will involuntarily deviate to the left. ”

Lao Xu took over the conversation and said: "What the fourth master said is what I want to express, in fact, this road is an ordinary loop, but the path is very long, and with the darkness, we don't feel that we will deviate from the original route when we feel like walking in a straight line." ”

In this way, in fact, the straight extension line from the place where we follow the rope down to the mural is the tangent of this circular road. In layman's terms, when we walked forward at the mural, we missed a correct intersection, and instead of entering the intersection in a straight line, we turned left and entered this circular road when we felt like we were walking in a straight line. And then no matter how we go, we are tossing and turning within this huge loop.

After thinking about this layer of mechanism, everyone's hearts immediately felt comfortable and stable. So we lifted our spirits and returned to the original point together. This time, we walked more slowly, using flashlights to keep looking for secret doors on the rock walls on both sides to escape from this circular road. Sure enough, after a long walk, we found a secret door on the rock wall on the right. After walking through this inconspicuous secret door, I walked for a while, and sure enough, I returned to the entrance of the cave and saw the murals on the rock wall on the side. Everyone couldn't help but take a deep breath and put their minds at ease.

got out of the predicament, and the choice was placed in front of everyone again. Do you choose to climb up the rope and fight the hundred and ten foxes outside, or continue to explore? The scholar hesitated and looked at me. I think the information revealed by this mural is worth studying, and it is better to explore such a place that seems to be an ancient tomb. And Lao Xu tried his best to persuade everyone to stay, saying that this may be a big discovery, maybe it can fill a number of scientific research gaps, and we must stick to it. The fourth master said very firmly that he would continue. The result of this 3-1 vote forced the scholar to decide to explore as well, and he comforted himself that he might find a lot of treasures.

Once again, the target is identified, so let's set off again and explore the place. We have a lot of equipment, and we buy military equipment and camping equipment, and we are still very confident in our hearts. This time, we walked close to the rock wall on the right, and sure enough, we found a secret door at the other end as a fork in the road. Passing through this secret door, there was no sign we had begun to make, and everyone breathed a sigh of relief that the circular road had been crossed correctly.

After walking along the road for a short time, I found a large stone cave. The top of this cave is very high, about five meters, so it is not oppressive at all. The scholar found something on the stone wall of this cave. These strange objects are cast in bronze and are shaped like oversized wine glasses, and on the top of this "wine glass" are carved a simple dragon, the dragon's mouth facing the "wine cup", as if it is about to drink water. Lao Xu looked at it with a flashlight, and said that these "wine glasses" are very similar to the common everlasting lamps in some ancient tombs, arranged in eight directions, symbolizing that the tomb owner can get the light forever, but these lamps seem to have no fuel in them, and they have been extinguished.

The scholar didn't believe it, so he had to use a lighter to light the wick and try it, but he didn't light it back and forth, "What the hell, why is the owner of this tomb so poor, he can only use a few lamps for decoration, and he is reluctant to buy even lamp oil." It seems that there is no good treasure to be found here. The scholar complained and walked back, and when he reached the center of the cave, he found a stone platform. The stone platform is very smooth and flat, and there is a monument with it, as if it were a chair made of stone. I was about to shout don't be blind, but the scholar had already sat down with a big grin.

I only listened to the distance and near, and faintly heard the trivial clicking sound, and then suddenly it lit up in all directions. It's not as bright as our tactical flashlight, but it happened so suddenly, and we've been getting used to the darkness for so long, and the world is spinning all at once. I tried to restrain myself, rubbed my eyes, and looked around. Oh my God, the eight ever-bright lights are on!
