"In addition to the skills brought by the Central Plains, there can be no other method for building tombs in Heiyun Village, so no matter what era the tombs are built, they are all the same."

Thinking of this, I sped up my search.

Caiyun saw my actions and searched on the other side of the coffin.

This time, though, hopes were doomed.

Caiyun and I quickly turned over the inside and out of the sarcophagus again, but we didn't pick up the white bones in the coffin and examine them one by one.

It's a pity that this is just an ordinary sarcophagus, and it doesn't reveal the slightest hint of hiding a secret passage.

Just as Caiyun and I gave up the sarcophagus and were about to expand the search area to the stone room outside, Uncle Ciwang on the side suddenly let out a cheer.

"Found it, here, here's the doorway." Ciwang ran over in two steps, grabbed my arm, and dragged me to the edge of the tomb wall at the entrance.

"Look, look at the clay over here, there's no difference." Ciwang excitedly pointed to an area about half a person tall in the corner.

I turned on the flashlight, shone it on his fingers, and leaned my face over to take a closer look, and there was nothing surprising about it, the same green bricks, filled with the same clay in the gaps.

"Old pot, I look the same, what's the difference?" Deyang Ram on the side was a little strange.

"Look at this place carefully," Ciwang stretched out a finger and pointed to the clay in one of the crevices, "Look at the clay in this location, and you won't see any difference." ”

Seeing Ciwang doing such a thing, I thought to myself that it must be something different, so I fixed my eyes and looked at the gap again.

On closer inspection, I could really see a difference, the clay in this crevice was a little darker than the other places, a very subtle difference, if he hadn't pointed it out, I wouldn't have noticed such a difference.

"It looks like the clay here is a little darker."

"That's right!" Ciwang patted me on the shoulder, scraped the clay with his fingers, scraped some soft clay between his fingernails, and then scraped the clay elsewhere with his other finger.

Holding two fingers in front of my eyes, Ciwang continued, "Not only is it darker, but it's also softer than the rest. ”

Looking closely at the clay blocks on his two fingers, there are indeed slight differences, the dry crumbs scraped off in the places where they are fine, and the clay blocks that hang down are slightly sticky in the places in question.

I had a vague understanding in my heart, dusted off the clay on my hands, and said, "This clay is called cooked soil, and it contains a certain percentage of lime paste, which absorbs moisture in the air. Judging from the scale of the construction of this coffin, in the outer layer of the coffin, if nothing else, there should be a sealing layer and a waterproof rammed earth layer to separate the coffin from the outside mountain. In this case, it is almost impossible for the water flow on the inner side of the mountain to penetrate the double blockade of the sealing layer and the rammed earth layer, and penetrate into the tomb, and a small amount of water is directly absorbed by the outer layer of soil. ”

"What does that mean?" Ciwang and Deyang Ram and others don't know why.

I continued: "But judging from the condition of this small patch of clay, it clearly means that it absorbs some moisture. So, is it possible that there are cracks in the outer layer of the sealed and rammed earth layers, allowing the water to come into contact with the coffin chamber of the tomb? This is not true. If the coffin is in direct contact with the water flow, then under the penetration of the water flow, the clay on the brick wall of the coffin should be soaked in a relatively large area, and it should not be just such a small area. ”

"Judging by the degree of softening of this clay, it is only in contact with moist air with a little moisture, not direct contact with moisture, so the signs of softening are not obvious, you say that means?" I looked inquiringly at Ciwang and Deyang Ram.

"This means that the circulation of air, that is, behind this small piece of clay, is not completely sealed by the rammed earth layer, there is a gap for air circulation."

"That's right, the more elaborate the mechanism, the more it is necessary to leave space behind the wall for cohesion and hinges, and judging from the situation of this clay layer, I can conclude that the secret passage switch of this tomb is near this location."

After saying this, the morale of the team was boosted, and next, we focused on this small area, carefully groping for the existence of the switch.

Discovering where the mechanism might exist does not mean that the switch has been exposed to us, it can only be said that it is a good start.

However, as long as the analysis is correct, it is only a matter of time before the switch to the dark channel is found.

Sure enough, within two minutes, we made a new discovery on the nearby green bricks.

I gently tapped a green brick near the clay, and it made a softer and crisp "click" sound, which was completely different from the "porphyry" sound of other green bricks.

The green brick was found, but what was hidden behind it was a mechanism or a switch in the secret passage, and I was not completely sure in my heart.

Although according to common sense, the trigger point of the mechanism should be in a more conspicuous position, and the switch of the secret channel can naturally be hidden, but before the answer is revealed, there will still be some nervousness.

As soon as I pressed my hand, my whole palm pressed down heavily.

There was a sudden silence in the burial chamber, except for the breathing of a few of us echoing through the space.

No traps were activated, no tunnels were opened, nothing happened.

We looked at each other, and our minds couldn't turn for a while.

But within a few seconds, we heard a muffled sound behind the walls on both sides, and then the whole chamber rattled and turned. We hurriedly held the coffin and watched the burial chamber slowly turn in the cacophony of the stone rubbing.

"Click!" About three minutes later, with a soft sound, the chamber came to a complete halt after turning one hundred and eighty degrees.

The entrance to the burial chamber where we had entered before, after turning one hundred and eighty degrees, led to another swarthy passage.

A cold breath poured out from the mouth of the passage, filling the entire tomb in an instant, making us shiver. It seems to remind us of the intruders of the uninvited guests that what we will face next is the horror of the deep world.

"Isn't it the tomb at the bottom of the lake?" Ciwang became a little nervous.

With doubts, we slowly walked forward. However, as soon as I arrived at that place, I was directly dumbfounded.

A pool of blue water appears in front of us like a mirror in the sky.

"This ...... This is the village of madmen? ”

"No, this is the village of madmen." Ciwang said affirmatively.

I got on the edge of the lake and put my hand in the water, "Ouch, it's pretty cold." ”

The place where we are is the lake under the big lonely mountain, looking at the blue and quiet lake and worrying, "Isn't this secret passage leading to the tomb at the bottom of the lake?" How did you get to Dagu Mountain? ”

By this time, the sun had climbed the mountain, and I was sweating profusely.

"Yun Ding'e did say that this secret passage leads to the forbidden land, the big lonely mountain and the small lonely mountain, not to say that this secret passage goes directly to the tomb at the bottom of the lake, perhaps, just near the road." Deyang Ram analyzed.

Suddenly, Ciwang shouted "Be careful". I hurriedly turned around, only to see Yu'er suddenly unusually, like a tiger out of the cage, pounced on me. I didn't have time to dodge, I was slammed by it, and the whole person fell backwards, falling directly into the bottomless blue lake, and when I fell into the water, I vaguely heard the screams of Ciwang and a few of them.

As soon as I fell into the water, I choked on the sour nose and mouth. I struggled to swim up, only to see a dark shadow flash overhead, and a huge object jumped into the water after me. I paddled my arms and gradually adapted to the underwater environment, and before I could swim out of the water, I realized that it was nothing else that had just fallen into the water, but Yu'er.

After knocking me off the lake, I jumped off for some reason. Yu'er moves swiftly underwater. It dived into the water and jumped up to me, constantly flapping its front paws at me, as if beckoning me to come with it. I held my breath for a long time, and if I didn't go up to breathe, I might drown at any time, but Yu'er refused to let me go.

The dog was quite stubborn, and when he saw that I didn't want to go with it, he grabbed me by the collar and swam straight to the bottom. I was caught by the collar by it, and the underwater resistance was very great, I waved my hands and feet to shake off its restraint, and the force was all melted away by the water, and finally I lost consciousness because of the lack of oxygen.

When I regained consciousness, my mind went blank, and in a trance I heard the clanging of horses' hooves, and then I seemed to see countless small blue fish swimming around me in unison. I felt like I had been run over by a car, and it hurt and hurt.

I let out an "ouch" and opened my eyes, only to see darkness.

But soon I calmed down, my eyes widened, and I quickly got used to the darkness around me, and I reached out and was blocked by a flat, shiny wall as soon as I reached my chest. I was shocked, I didn't know where I was, I just knew that I was lying flat at the moment. I took advantage of the situation and felt to other places, but the way out was all blocked, and there was no room to sit up. I slowly realized that I was trapped in a small object.

I took a deep breath and felt that the air was not cloudy, there was fresh air flowing, this time I was a little relieved, and then I started to investigate my situation. I tried to shout a few times, but I didn't dare to shout too much, in such a nearly completely enclosed space, yelling too much would only hurt my ears.

Sure enough, I shouted a few times, and the sound was humming, reflected off by the solid wall. I clenched my fists to my chest and struck hard upwards, but there was no movement. I tried everything I could, and finally determined that it would be difficult for me to escape from this confined box-shaped object unarmed.

I closed my eyes and commanded myself to calm down, and then I began to wonder what this place was.

First of all, I was dragged into the water by Yu'er, and finally lost consciousness. I don't know how long the interval was, but I don't think it will be too long. And then what? Yu'er dragged me into the water, obviously purposefully and directionally, and I seemed to hear the sound of others falling into the water. There were just a few of us by the lake, and the more I thought about it, the more irritated I became, because this place was so small and dark that it was like a coffin!

A thought crossed my mind, and I hurriedly reached for a gap in the wall, and sure enough, I found a curved gap near my head.

I was sad and happy in my heart: damn it, Lao Tzu was nailed into a coffin. The arc was the mark of the nail that had been hammered in.

Perhaps out of instinctive fear, although I figured out where I was, my heart became heavier and I couldn't help but slap the coffin lid again.

"Fuck, Lao Tzu won't be buried as a drowned ghost!"

Just as he was thinking about it, there was a faint knocking sound outside. I calmed down, put my ear to the coffin board and listened for a while, and vaguely heard someone calling my name. The sound seemed to come from many layers of things, but it felt like there was more than one person.

I made sure it was the voices of Ciwang and Deyang Ram, and I couldn't help but shout: "I'm here!" ”
