I had no place to vomit when I was bitter, and there was nothing I could do but defend passively.

After the five sand wolves stared at this direction for a while from such a distance, one of them turned around and walked away. As soon as it left, the remaining four followed.

Just gone? I don't feel very reliable, I haven't been in contact with sand wolves, but I know that wolves in other places are very smart when hunting, and even good at using some tricks. I wondered if the sand wolves were playing with something, so I stayed where I was.

The five sand wolves gradually disappeared into the desert under the moonlight, their steps still not fast, but their steps were already showing haste. Traveling so far that they must get to the place where there is aquatic prey early.

I stayed where I was for at least an hour, and finally I was convinced that the five sand wolves were really gone. I wondered, the doubts lingered in my heart, isn't it strange that five hungry sand wolves have found their prey, but they don't round it up?

I took the camel and slowly walked to the place where the sand wolf had just stayed, and I judged correctly, the sand wolf was staying in front of the clay pipe that I had accidentally discovered.

Thinking back to their previous actions, I vaguely realized something else. These sand wolves found the camels, and they must have discovered me, and the reason why they did not besiege was not because they did not want to, but because they did not dare.

What are they afraid of? What deters them?

The desert is full of yellow sand, but the clay pipe buried in the yellow sand is like a hole connected to the ground. The inside of the cave could not be reached, and even the light shone into it, and it was swallowed up immediately.

I carefully organized a backpack and put everything I could fit in. There was not a single tree nearby, nor a single stone, and the camels were left outside and could get lost. I got a reinforcing stake and a steel drill and bolted the camel to the side.

When I re-entered the pottery pipe, I hesitated for a moment, and it was obvious that there was probably something in the place where the pottery pipe was connected. But after so much effort to find this place, I would be very unwilling if I didn't go down and have a look.

I slowly climbed underneath the clay pipe, which was rough and covered with a layer of sand, and once I sat on it, it was like sitting on a slide. I used a shovel to clear some of the sand off in front of me, so that the speed of the slide was well controlled. I think that if the pottery pipe is extended at this angle all the time, then even if it slides down a long distance, it can climb back, and it just takes a little effort.

I slid over the first pipe, then to the second, and as time went on, it got smoother and smoother. During this period, I have been paying attention to the changes in the oxygen content of the air, I came out of the ancient line, even if I have never been in the pit, I have heard other people say that if the underground cavity with a small space has just been opened, it will die if you go down directly without ventilation.

However, the changes in air quality are so subtle that they are not noticeable. This shows that the area of the place where the pottery pipe is connected should be relatively large.

I slid straight past almost ten clay tubes, and the light from the flashlight suddenly difed and weakened in front of me. I feel like the clay pipe should come to an end.

Sure enough, the pottery pipes really came to an end, and what these pottery pipes connected was a huge cavity that I didn't expect at all.

The sand layer of the desert is not particularly thick, and the sand is mostly formed by long-lasting weathering, which does not penetrate too deep into the ground. Therefore, there is generally a mixed layer of rock and soil underneath the sand layer. The underground cavity I saw was not naturally formed because it was too neatly shaped.

In other words, this huge underground cavity was completely excavated by manpower.

The strong light of the flashlight could not illuminate the whole space, so I stood there and slowly glanced left and right. There was not a single sound here, and it was silent as if thousands of people had never come.

It was empty, and there was nothing to be seen in the whole space, except for a few pillars that were too thick for three or four people to hold.

The raw materials of the pillars are all logs, and I guess that the logs are not products of Central Asia, but should have been transported from Europe or the interior of the Central Plains at that time. The manpower and material resources spent on transporting such a giant log along the way have far exceeded the value of the wood itself.

The ground is very flat, it is all tiled with soil and then tamped, and after thousands of years, the rammed earth has been as hard as bricks. On the level ground, three paths can be seen, all the way to the other end of the space.

Why did people build such an artificial cavity centuries ago? It doesn't seem to have any practical use. If it is useful, then the only use may be for many people to gather here.

I watched for a long time, making sure that there was no danger in it, and then I took the first step, slowly walking along the middle path.

It was really empty, and as I walked, I kept glancing, and all I could see was the pillars that stood in between. After walking for a while, the beam of light of the flashlight was able to reach the scene in front of me, and I saw a door.

It was a quaint, one-piece stone carved gate, thick and heavy. Since there is a door, it means that there is an unexplored space behind the door. When I walked up to the stone door, which was at least five meters wide, the first thing I saw was a few carved characters on the door.

I thought that the script found in this place should be the script that was commonly used in the area a few years ago, but after recognizing the characters, I was puzzled.

I don't know the characters on the stone gate, but when I saw the characters, my intuition told me that it was Zhangxiong.

I can make out some of the Zhangzhung sacrificial texts, and the Zhangzhung sacrificial texts are derived from the Zhangzhung script, or rather, the Zhangzhung script is bred from the sacrificial texts, and both possibilities are possible.

Zhangxiong Sacrifice Script, Zhangxiong common script, these two characters actually belong to the same lineage, to put it bluntly, it is equal to the difference between Chinese characters and Japanese.

When the ancient Zhangxiong Dynasty was at its most powerful, its territory never expanded beyond the Qinghai-Tibet Plateau, let alone Central and West Asia. The only thing that can explain the problem is that the information I got before is quite reliable, when Chepan City was prosperous, as a very important transit hub of the Silk Road, Zhangxiong people once had an office in Chepan City, it is because of such an institution, so many Zhangxiong people have come to Chepan Ancient City.

But the Zhang-zhung people are only outsiders here, and without the support of the local authorities, the Zhang-zhung people would not have been able to build such a vast civil engineering project without much practical use.

I can recognize some of the Zhangzhung texts, but I don't know anything about this ordinary Zhangzhung script. I don't understand what the Xiangxiong text on the stone gate means.

However, this empty space has come to an end here at the Stone Gate, and if you want to continue exploring, you must pass through this gate.

I looked at the stone gate, and it would be too much trouble for such a heavy stone door to be pushed open by someone every time. Under the stone gate, there are several grooves that are very regular, and the stone ball is made of hard and load-bearing stones such as granite, and placed in the place where the stone door and the groove are connected, which is a very primitive and simple mechanical combination.

But the force produced by such a mechanical combination was not as great as I imagined, and I used all the strength to feed, and the stone gate did not even move.

The idea of preparing to explore in my heart was suddenly completely extinguished. Faced with this kind of problem, it is not possible to solve it by finding a solution.

I ran to look elsewhere, and the three roads on the ground all lead to this stone gate, and the door is the only entrance, and you can't enter the space behind the door without passing through the stone gate. I ran back and forth at least five or six times before I got back to the stone gate.

I can't open this stone door, even if I know what clues may exist behind the stone door, but if I can't open this door, everything is empty talk.

Click......

At this moment, I heard the stone ball under the stone gate seem to ring, and then the huge stone gate seems to be pushed by an invisible force, and a gap about two meters wide is rumbling open. The stone gate has not been opened for I don't know how many years, and the dust is falling downward.

I was startled by the movement of the stone gate, and I retreated far back. However, the stone gate opened a two-meter-wide gap and then stopped.

The stone gate was still, and the surroundings fell into an unspeakable dead silence. My heart was completely hanging in my throat because this phenomenon was so abnormal.

I stood for at least ten minutes or so, and when I was facing the closed stone door, I wanted to think of all the ways I could and push it open. But when the door actually opened a gap large enough for me to pass through, I was at a loss.

I tentatively shone the beam of light from the two-meter-wide gap, which was not small, and it looked like there was some mess.

I tried several times, throwing water bottles and compressed dry food through the crack in the door, and the things were thrown over, and there was still a dead silence. After hesitating for a while, I gritted my teeth and walked through the crack in the door.

Behind the stone door, there is a boxy space, and when I walked in, I saw that there were three large holes in the wall on the left-hand side, and the holes were load-bearing arched holes. If you pass through these three openings, you may have to go to other spaces connected to them.

There are some stones here, large and small shapes, on the wall on the right, there are continuous murals, but after too long, the pigment used in the murals has fallen off, causing the walls to be mottled and the murals can no longer be distinguished.

The space behind the stone gate may not be of much use, but only as a connection point between spaces. I feel that the three arched holes on the left hand side are the key points to explore.

Without thinking, I walked to the left. There are three vaulted holes, and I don't know if there is any mystery to them, so I have to carefully choose a hole that is generally safe.

As I walked to the left, a syllable seemed to faintly come out of the silent corner of the space.

"Come ......"

In this environment, any sound can alert me, and when I hear this faint syllable, I immediately stop and turn around involuntarily.

I couldn't tell where this syllable came from, but the moment I turned around, I suddenly felt that the atmosphere in the space was wrong.

In the silent space, the dead silence seemed to be broken by something, and I felt that a force that I could not see was slowly diffusing and drifting away.
