"No, it's the mechanism that opens the entrance to the passage! It's hard to figure out, because it's not only tall, but it's also spacious, and it's hard to figure out the switch. Pen, fun, pavilion www. biquge。 I don't know how to go up and trigger it after I find it! ”

"No matter where you are, find the switch!" Professor Li said, "Let's look for it! Captain Cao, you can arrange it! ”

"Okay!" Captain Cao replied.

It's big here, and we're in small groups looking for switches. For safety reasons, each group was accompanied by at least three military personnel, in order to deal with the possibility of returning blood bats.

At this time, I noticed that the roof of the cave was not only high, but also full of uneven stalactites. This construction makes it difficult for us to find. Because there are many gaps between stalactites and stalactites, some large and some small, we must carefully look at each gap to make sure that there is nothing unusual in it before continuing to look forward.

The shallower slits can see what's inside at a glance, but the deeper crevices are very eye-catching. There were some crevices that were so crooked that the flashlight couldn't shine in, so we had to mark them and wait until the end to figure it out.

Although we searched with great difficulty, fortunately there were many people, and after searching for more than an hour, we went through all the places within a hundred meters of the vicinity.

When we got together, we counted the data. There are five places where the gap is due to the skew, and there is no end in sight. There are two other suspicious places. The first is a small hole in the wall at the end, four or five meters above the ground, and the hole is the size of a fist. Professor Chan estimated it was a vent. There may be space behind the walls. The second suspicious spot was that there was a metal-like object on the left side of the cave roof, which was octagonal, dark green, and the size of a fist. It is sandwiched between two stalactites and cannot be found unless you search very carefully. Master Zhang thinks that it is the switch of the mechanism.

Now the question is how to go up and touch the mechanism. It's more than ten meters here, and there is no place to climb around. Even if the switch is right in front of you, you can't touch it. We were quite helpless.

"Master Zhang, how do you say that mechanism will be activated?" Ma Lu asked.

"There are generally two ways to trigger, one is to press it down, and the other is to turn it! In ancient times, there were basically two ways to trigger mechanisms. ”

"Which one do you think is more likely?" Ma Liu said as he took out the pistol from his waist and loaded it.

"The switch is in an octagonal shape, both are possible! What are you doing? ”

"Can only give it a try! It's not an option to wait here! Ma Liu said, "Don't move the lights!" He said as he aimed his pistol at the switch.

"Wait a minute!" Master Zhang said, "If it is not pressed, but rotated, if the bullet breaks the switch, we will never be able to enter!" ”

Ma Lu stopped and said, "Who has a better way?" ”

No one spoke at this point.

Ma Lu shot at the metal block at the top of the cave, hitting the middle of the metal block. Everyone waited quietly, but nothing happened. Ma Lu then fired several more shots at the metal block, all of which were hit. Although a target more than ten meters away is easy for an ordinary sniper to hit, in such a dark environment, Ma Lu can still hit every shot, and I have to admit that his ability is very strong.

With a few shots hitting, a sparse metal grinding sound rang out from the roof of the cave. We felt that Ma Liu's shots should have been fired correctly, and we waited with excitement and uneasiness for the passage to open.

But to our surprise, there was no sign of the mechanism activating around us, and the sparse grinding of metal had stopped. Then the octagonal metal block on the roof of the cave fell down. We all rushed to dodge.

The sound of heavy metal falling to the ground echoed throughout the cave.

"Ma Liu, you seem to have messed things up, you knocked down the switch!" Ah Chun said.

Everyone looked at the horses!

"This ...... "Ma Liu was embarrassed and didn't know what to say.

"Oops! I didn't think of that! Master Zhang said, "The switch is too old, and it must be rusty." Touch it twice and it's broken! ”

"Master Zhang, you're too late!" Ma Liu said, "What now? ”

"It's all because you're too impulsive!" Ah Chun said.

"I just asked who had any other way, and no one answered me before I!" Ma Liu said.

"Don't make any noise!" Captain Cao said, "Master Zhang, is there any other way to get in?" ”

"Wait until I think about it!" Master Zhang said.

Actually, I didn't want to go into the ancient ruins, because the strange arrangement of the government and the strange encounter last night made me very uneasy. It's best to find the entrance and go back the way you came.

I saw Master Zhang use a flashlight to shine on the place where the octagonal metal block was originally inlaid, and after the metal block fell, a black thing was revealed, but due to the lack of light and relatively high, I couldn't see what it was.

"Shoot two more shots at that black thing," Master Zhang said.

Ma raised his pistol to aim, and then struck it precisely at the black object.

There was a grinding sound of metal and stones. We all looked on both sides, and before we found the end of the road, we noticed a large rock slowly lifting up directly below the vent.

"That should be the passage!" Master Zhang said.

This is not good news for me. For most of the members who joined the archaeological team without knowing it, it is probably not good news.

We packed our bags and headed for the aisle.

As soon as I entered the passage, a cold wind blew in my face. Aren't caves always warm in winter and cool in summer? It's winter, why is there a colder wind blowing inside? It was not just the coldness of the temperature, but the coldness of my heart, and I felt inexplicably panicked.

I took a deep breath. Suddenly, I heard a very soft laugh in my ears. The voice is sharp and thin, and it is impossible to tell whether the person who is coming from it is a man or a woman. I shuddered. I looked on both sides in a panic, who would be so boring and pretending to be scary in this kind of place?

I saw Xu Li on the right, and she was telling Dr. Wu what medicine they had brought. On the left is Ah Chun, who checks his pistol as he walks forward. Both of them are doing their own thing, not like pretending. And as far as I understand, these two are not the kind of people who are so bored that they pretend to be scary.

"What's going on?" Ah Chun loaded the magazine of his pistol and asked me, "Did you take the wrong medicine?" ”

I looked behind me and behind me was a group of soldiers, all walking quietly. They all looked at me strangely when they saw me looking back.

"What's wrong?" Xu Li asked me, "Your face is not very good?" ”

"Just now...... Did you hear the laughter just now? ”

"What laughter? Nope! Dr. Goh, did you hear that? ”

"Nope!" Dr. Goh said, "Who can laugh in this environment. ”

"Are you going to be too tired and have auditory hallucinations?" Xu Li said.

"Hmmm! Chances are, I'm a little tired! ”

"I hope this archaeological mission will end soon, and you will be able to go home and rest!" Xu Li said.

The laughter was soft, maybe it was just my auditory hallucination, I hope so. I don't want anything to go wrong. Just like Xu Li said, I just want the mission to end quickly and go home as soon as possible. Because the fatigue of yesterday's mountain climb and the strange thing last night were enough for me. You know, before yesterday, I had been working in the forensic department of Guangzhou since I graduated from university. I've been working for years, and my job is either sitting in the office drinking coffee or facing a cold corpse, and I rarely do anything that is both physically exhausting and stressful.

At this time, I realized that this place was no longer the appearance of a cave outside, but like a straight secret passage, and it was not wider and wider as it went, and its width remained basically the same. The road on both sides is much narrower than the cave you entered, the ground is paved with stone slabs, and the walls on both sides are fairly smooth. On both sides of the road are iron basins, which contain wooden strips, presumably used for lighting in the past.

The road on both sides has always been exactly the same structure, and we have been walking for almost two hours, and we have become tired of this kind of road. I shone my flashlight forward, but I still couldn't see the end. The light of the flashlight was swallowed up by the endless darkness. It was as if the road would never end.

In order to deal with the sudden danger, we formed a siege formation, and the soldiers surrounded those of us who needed protection. Master Zhang, Professor Li and Professor Chen were in the front position, and they were constantly looking at the situation around them. It's the same everywhere here, and I don't know what they're looking at! What can you see?

At this time, they stopped, and Master Zhang said, "It should be nearby!" ”

"What?" Ma Lu was surprised and said, "What will be around here?" ”

"An entrance to the lower levels!" Master Zhang said.

"It's the same everywhere here, how do you know it's going to be around here?"

"Based on the Liangyi Formation and Professor Chen's research on architecture." Master Zhang said as he groped around the wall, looking as if he was looking for a switch to trigger the mechanism.

Professor Chen and Professor Li were doing the same on the other side of the wall.

Soon, Master Zhang didn't know what he had pressed, the ground shook slightly, and a stone slab rose up on the right side of the wall, and then a staircase leading to the bottom appeared.

Everyone sighed at the ability of Master Zhang's three people. According to metaphysics and architecture, you can find out the secret passage switch hidden by the predecessors. Plus an experienced archaeologist, Professor Li. My heart immediately relaxed a lot, and although there was still a lot of uneasiness, it didn't continue to swell.
