For safety reasons, we decided to advance and retreat together, so we lined up in a column, and I led the way at the front, with willow leaves sandwiched in the middle, and my big teeth broke behind.

The front hall was empty and echoed very loudly. Even if the noise was inadvertent, it was like a high-power loudspeaker, buzzing in my ears, and the lingering sound continued.

Stopped and waited until the light gathered, you could clearly see a door in each direction in the southeast, northwest and north. Daya looked around and was a little confused. His eyes turned and asked me carefully: "Let's Liang, where are we going? There are too many doors. Is it the only one that paid for by any door factory? It's like this one doesn't have money, why are you doing so much?"

I heard it funny, looked at the other three doors, and lowered my voice and said, "The door we just came out should be the gate of the east ear chamber, the door opposite should lead to another ear chamber, the gate on the south should be the main entrance of the underground palace, and the gate on the north should normally lead to the depths of the underground palace."

After hearing what I said, Liu Ye and Daya also took photos with flashlights. They were a little curious, and I don’t know why I said so sure.

I shine the door leaf of the stone door on the south side with a flashlight, then shake it, telling Liu Ye and Daya: "The door leaf of this door is the thickest of all doors, and it is the only door that has not been opened. And the long stone behind the door that holds the door should be a "stone".

Liu Ye also illuminated the flashlight and nodded thoughtfully and said, "I have heard of this kind of 'project stone' before. It seems that there are grooves on the ground. Before closing the door, the lower part of the project stone is placed in the groove on the ground, and then leans against the stone door. There are pre-made convex grooves behind the stone door. After the door is slowly closed from the outside, the projected stone will press against the stone door from the back. There are convex grooves on the top and grooves on the bottom. It is very firm and cannot be pushed open from the outside. This seems to be a common method used to prevent tomb robbery in the past. It should be called a great invention by the ancients. I have heard of it, but this is the first time I have seen the real thing."

In fact, I have heard of this kind of thing before. Like Liuye, I went to the underground palace to "visit" and it was also the first time that the big girl got into a sedan chair. It is said that some masters of the backfighting can open the thick stone door from the outside within five minutes, and when they cracked the "stone", they had a special tool called the "snail key".

The "Crooked Nail Key" is made of a very tough steel bar, and the thickness is strictly regulated. The steel bar is bent into a half-mouth shape and sharpened the top. When using it, the key is poked into the crack of the door, and the upper part of the stone is bent into a half-mouth shape. While pushing the door hard, the stone is pulled to the side. The purpose is to move the lower end of the stone out of the groove and lose its fulcrum. In fact, as long as the door is opened, the subsequent things will naturally be easy to handle.

Looking from here, except for this gate, the other three gates were already open. I don’t know if it was because it was rushed when evacuating, or because someone came here to open all the gates. No matter what, it saved us trouble. Otherwise, even if these gates knew how to open, there would be no tools to help, and it would be very likely that they would return without success.

The width of the front hall is about six meters, and the depth can reach twenty meters. The three of us walked carefully to the door of the Xier Room and were amazed when we saw the carvings on the pillars at the door. It was really a magical work.

There seemed to be nothing worth noting here, so I took the lead in walking towards the nave. The door of the nave opened a very wide gap, and the three of us easily squeezed through the door and walked in.

The layout of the middle hall is similar to the front hall, but it is a little larger than the front hall. It is connected to the front hall and the back hall, and there is an ear chamber on the left and right. This should be the center of the entire underground palace. The interior floor is paved with fine square bricks, and a sacred seat is located in the middle, which looks like it is made of white marble. There are four wolf heads carved on the backrest. The wolf stretches to the front of the backrest to make a howling sound, and cloud patterns are carved on both sides of the armrest and the outside of the backrest. There is a large table in front of the seat, with a copper incense burner, the size of a soup bowl, reflecting the faint and cold light. Two candlesticks and four vases are placed symmetrically beside the left and right, and there is a large blue and white porcelain jar on both sides of the seat.

We walked to the large blue and white porcelain jar in a few steps, looked down and looked in. The jar was filled with lamp oil of most of the tank. A copper round float was floating on the oil surface, with a wick as thick as a finger inside. It was probably the so-called "Eternal Light". It is said that the lamp oil used for "Eternal Light" is the oil of the "mermaid" in the sea. The grease is very resistant to burning and can burn for hundreds of years.

Daya glanced at the two jars, thudded, and said to me, "Come on, this is the 'Eternal Light', right? I didn't expect that there would be such a play. God said, there should be light..." As he said that, he reached out and lit the wick in the copper float with a lighter.

I didn't have time to stop him, but I saw the wick splashing twice, and then the flames shook twice, illuminating the surroundings in an instant.

This kind of floodlight is much more useful than the point light source of flashlights, and the entire hall also shows a rough idea. The plane of the nave is also rectangular in a longitudinal direction, about six meters wide and more than twenty meters deep. The roof of the room can be more than nine meters high, making it a longitudinal stone arch structure. The door leading to the back hall is particularly spectacular. The pair of monster heads with eyes and grinning on the head of the door pavilion, with flames flickering, and it feels like it is alive, hideous and terrifying, and it makes me feel a little panicked.

After looking around, nothing unusual was found in the middle hall. Just as I turned around, I was about to ask Liu Ye and Daya to go to the ear chamber next to me to take a look, but suddenly I found that the shadows on the ground were actually of four people.

As the swaying light swayed, the extra shadow stood behind the big teeth. Judging from the shadow, my body was not tall, my head was small, and my ears seemed to have a little sharp and thin. This scared me so much that I was sweating all over. I blinked my eyes a few times, and I was sure it was not an hallucination. I pretended not to care and looked at the back of the big teeth. It was so dark that I could not see anything.

I didn't dare to make a statement, but instead pretended to tidy up my backpack with calmness, winking at Daya and Liuye. Liuye and Liuye looked at me and winked at me, but I didn't understand why, so I was so anxious that I secretly pointed down with my hand. Only then did they understand what I mean. When they looked down, their faces changed immediately.

As the fire flashed, the extra shadow lay motionless behind Big Teeth, making our scalp numb.

Big teeth gritted their teeth, and did not dare to turn back rashly. I guess I was so scared that I had already had fine sweat beads on my forehead, and I slowly put my hand on the dagger.

Once fear arises, it will pass by like a huge wave in an instant. Staring at the shadow on the ground, every second it lasts, fear increases exponentially.

I made up my mind and simply didn't do it, and bit the tip of my tongue hard. In the past, except for accidentally biting my cheeks, I never deliberately self-injured. I thought this move should be very casual and stylish, but I thought that as soon as I bit my tongue, I grinned. This pain is probably not much better than sticking bamboo sticks on my nails. It seems that this self-abuse really requires courage.

I held a mouthful of blood in my mouth, raised my head suddenly, and squirted out my mouth behind my big teeth.

I saw a burst of white smoke coming out of thin air behind Daya, as if something was burned. I reached out and pulled Daya and Liuye over. After looking at the white smoke opposite, I gradually returned to calm and could not see anything.

Daya was also frightened and sweated. After looking at the feet, the shadow disappeared. We were all a little frightened. Daya panted and asked me: "Let's go, what was the one I was playing with just now? Mom, who did I mess with? First, I pinched me secretly, now I'm going to do something bad behind my back. It's really bad for eight lifetimes!"

I glanced at Big Teeth and shook my head: "Although I don't know what it is, it is definitely not a serious thing. The 'true saliva' I just vomited just now probably hurt it, so I might have hid where to hide."

After saying that, I patted Big Teeth, which was still cursing and muttering, and then advised him: "Big Teeth, believe that the earth is moving, and a person will never be in an unlucky position forever."

Big teeth rolled over their eyelids and looked at me: "Don't fart or mix sand, even sarcasm and blows. My buddy is not an ordinary soldier. I will remain unmoved by the wind and waves!..."

Just as he was talking, Liu Ye suddenly pulled my arm gently, glanced at the seat in the hall, and stuttered in a low voice: "Hu...Brother Hu, look at that seat, there seems to be... blood on it!"

Daya and I quickly stopped talking and looked over there. After looking for a long time, we didn't see any blood at all. There was nothing on the seat. Daya and I turned around with confusion and looked at Liu Ye.

When Liu Ye saw our expressions, he realized something was wrong. He pointed at the seat nervously and his body trembled a little: "The seat is bleeding down, drop by drop, dripping, not when he came in, and what he had just happened, you... can't you see it?"
