The room where the sound came from was the room on my left near the cave passage, and the room on my left that was furthest from the main hall a kilometer away. In this uninhabited dungeon, the sudden sound made my heart beat wildly again.

The sound seemed to be the friction between iron and stone, rhythmically beating and beating.

If this sound appeared in other environments, it would not be too prominent, but in such a quiet confined space where there was no wind at all, this sound would be very clear and harsh! People can't help but feel a little creepy, even if I have the experience of "Ghost Cub Ridge", it still makes my skin as if it has been crawled by a snake, cool and slippery, uncomfortable, and the hair stands up unnaturally.

The architecture of the Western Han Dynasty follows the style of the Qin Dynasty and the pre-Qin Dynasty, and follows the architectural concept of "craftsmen camp the country, square nine miles, three gates next to it, nine longitudes and nine latitudes in the country, nine tracks along the way, left ancestors and right societies, facing the future market".

As the tombs of the Han Dynasty, they are generally made of bricks, with bricks instead of coffins, and the size of the tomb where the coffin is parked is modeled after the size of the master's residence before his death.

Of all the buildings, the room that made the sound was the most inconspicuous, and at first my attention was completely drawn to the building of the main hall directly opposite me, and then I looked at that room.

To my surprise, I found that the door of the house was ajar, and from the exposed crack, there was a black hole inside, and the uncomfortable grinding sound came from inside.

From the time I found the rope on the cliff wall until I entered the dungeon, the "tomb robber" who came here before me was nowhere to be seen, and there was no trace except for the rope. I thought something had happened to him, but now it looks like he's in the building that made the sound.

I don't know if this voice has anything to do with him, but normal people would never make such a sound, unless there is something hidden! All the puzzles are inside this building, which is about five meters high and ten meters wide.

I looked at my watch, the hour hand was at 5:45 p.m., this time surprised me a little, probably because of the illusion caused by the dim candle flame in the underground palace, which gave me the impression that it was already late at night.

In fact, it only took twenty minutes to pass the cave full of painted murals, and it was only about ten minutes to look around after arriving at the underground palace.

After some hesitation, I decided to lean towards the room where the sound came from, but before I could fully make up my mind to explore, my curiosity controlled my steps towards the room.

If you say that you are not afraid, you would be lying, but it takes a lot of courage to be alone and doing such an activity for the first time in such an environment, in such a confined space.

Now that I think about it, at that time, I was disturbed by my father's suicide, my second uncle's mystery, and a series of confusions that I couldn't live a normal life, so even if I was afraid and dangerous, I had to approach that mystery.

I put the map of the dungeon back in my backpack, holding a flashlight in my left hand and a dagger in my right hand, and tiptoed towards the room like a thief.

The candlesticks were still some distance away from the buildings on either side, and the light from the candles could only illuminate the road in the middle, and the buildings on both sides could only be hidden in the mist.

The pitch-black room is about five meters high, and the brick eaves and cornices and arches are clearly visible. As I got closer, the sound of friction became clearer and more piercing, and my heartbeat beat rhythmically with the sound, but it was no longer where it should be, it was beating close to my throat.

In this way, I continued to walk up the stone steps in a nervous state and stood in front of the wooden window on the side of the cave wall. The voice was only about five meters away from me, and there was a wooden door and two wooden windows between us.

The shape of the wooden windows in front of me is arranged one by one like the rib bones of a cow, and the silk cloth is sealed between them, which once again confirms the age of the building here, because the windows were sealed with paper after the Song Dynasty.

The sound in the room was still ringing, and I couldn't see it inside because of the silk cloth, and the only place I could see was the half-hidden crack in the door.

Because it is isolated from the wind and water, the silk cloth is well preserved and there is no trace of weathering. The idea that I wanted to peek through the window was shattered.

When I approached the half-open door and looked inside, I was stunned by what I saw inside.

I saw a candle in the southeast corner of the room, and although the flame was faint, it showed no sign of extinguishing, but the color of the flame was blue. The area of the room is about 100 square meters, except for the southeast corner where the candles are placed, and the surrounding area is hollow.

Just now, because it is far away from here, the candlelight of the nine candlesticks in the space cannot illuminate the situation in the crack of the door, and there is no imaginary darkness after approaching at this time, coupled with the faint light of the candlelight in the southeast corner, so that the outline of the room can be roughly distinguished, even if it is not clear.

What attracted me more than the candle with the blue flame in the southeast corner was that there was a person in the middle of this room! A fat man in camouflage uniform, in such a highly nervous situation, I can still pop up the word "tiger back bear waist" in my mind, because when I saw him, I really understood the meaning of this word, if every idiom to describe people has to find a spokesperson, I think, the spokesperson of this word is none other than him!

In front of him there was a pit about two meters wide, the depth of which I could not see clearly, which extended longitudinally to the wall of the house opposite me. His legs hung in the pit, his body was on his side, one hand touching the stele, and the other hand holding a shovel digging the junction between the stele and the floor tiles. He dug the bluestone in front of him, and the side of his face showed a strange smile at the same time.

Judging from the upside-down package on his right, and the things that came out of it, this fat man who was making strange movements and showing an incomprehensible smile was the "tomb robber" who came here before me! The shovel in his hand that is digging bluestone is what I need when I study archaeology, the sapper shovel!

Just as I was engrossed in watching the strange situation in front of me, something happened suddenly! The fat "tomb robber" who was originally concentrating on digging bluestone suddenly turned his head to look at me! That weird smile also retracted!
