The dark door was horizontally in front of us, and the white cloud patterns on the door were reflected by the yellow ancient lamps of bronze beasts, making people look up. It was probably the same for Brother Shunli. The two of them felt the same way. They reached out to push the door. The two of them increased their hands and the door opened with a creaking sound. Unexpectedly, there was light in the hall! We immediately became alert, waited for a while, and there was no movement, and then we tried to slowly enter the hall. When we came in, we found that there were several bronze ancient lamps on the walls around the hall, which were the same as outside the gate, which also emitted yellow light.

The moment I stepped into the hall, I vaguely smelled the fragrance that rushed straight into my brain. I looked around, and the others seemed to have not noticed it, and were still carefully exploring the hall. Could it be that I was suspicious? Maybe it was because my nerves were too tense and it was easy to associate.

"Are the lamps here also eternal lights?" asked the scholar.

"It should not be. Although modern science cannot make a conclusion on the principle of the eternal lamp, the general view in the archaeological community is that the reason why the eternal lamp can be bright and never fade is divided into two possibilities. One is the efficiency of fuel, and the other is the timeliness of lighting." Lao Xu replied.

The scholar imitated Lao Xu's tone: "The so-called high efficiency means that the fuel is relatively durable, such as the legendary mermaid oil used in the Mausoleum of the First Emperor. The so-called timeliness means that the lamps in some tombs have been designed to be clear when people come and when people go, making people feel that the lamps are always on and bright when they are bright. I'm right, Professor Xu?"

Lao Xu pushed his glasses: "That's right, it's also good for children. That's right, so I said that the lamps here should not be eternal lights. If you look closely, all the lamps here are exactly the same as the two outside the door. I noticed this structure when I was outside the door, and it was impossible to store too much fuel. From archaeological discoveries to modern science, as far as I know, there is no such flame-resistant material that can provide thousands of years of combustion with such a small volume. As for the timeliness..." Lao Xu lowered his voice and continued: "Do you still remember that he came out of the small path and was so dark around him, but before we fired the flares, we had already discovered this palace, which was actually because of the two lamps outside the door. What does this mean?"

"When we walked out of the trail, the light outside the door was on. It is very likely that the light outside the door did not light up as we entered, but was on!" Linglong replied.

Everyone stopped talking, and now we all realized something. The lamps here do not rely on "efficiency" or "timeliness". So, what has been able to keep them shining for thousands of years?

"This shows that someone has been managing these lamps, constantly injecting fuel into them, and maintaining lighting." The Fourth Master said the key point we realized.

My hair stood up like my hair, and my brother Shunli immediately took out his gun, turned on the headlight, and looked around.

The surroundings are still silent.

Lao Xu changed the headlight to a battery, then adjusted the focus of the headlight, and began to investigate the situation everywhere. There was nothing else in the hall except for a few wooden pillars that were thick and thin. There was only a few bronze beast-shaped lamps on the wall, which looked like ghost fire, and there was no valuable clue.

We didn't find anything and stared at Lao Xu. After all, he was the authority in archaeology. After Lao Xu turned around, he suddenly looked up and fixed the light column of the headlight above his head. We were startled by him and all followed him to shoot the headlight towards the roof.

Several lamp posts gathered on the roof, illuminating the sky. I saw that the roof of the hall was designed with a dome. On the inside of the dome is a large octagonal frame, and the inside of the frame is round. The round material cannot be seen, but under the illumination of the headlight, strange light continues to shine.

"It's amazing! This is really a miracle!" Old Xu was so excited that he ignored the academic identity and pulled Linglong and the Fourth Master and said, "Do you know that no complete pre-Qin buildings have been found in the archaeological world. However, in the sporadic records of documents and the site investigations of archaeological world fragments, it can be concluded that from the late Warring States Period to the pre-Qin period, the manufacturing process of architecture has developed rapidly, and the ancients could build many palaces and tombs that modern people could not imagine. However, in the pre-Qin period, the general palaces were flat roofs or sharp-angled roofs, and dome-like buildings were almost unrecorded in the literature. Perhaps the Keyan tribe absorbed the architectural characteristics of the Central Plains and the Western Regions, and integrated them to develop its own unique architectural style."

"Master Xu, don't be excited. There is something wrong with this." Ashun said, "Everyone has turned off the headlight."

We didn't understand why, and turned off the headlights as Ashun said, and then looked up at the dome. I saw that under the light of the ancient bronze lamp, the entire dome was slightly shining with countless light spots in the dark shadows, just like the night of late summer and early autumn when I was a child, lying in my mother's arms in the arms of my mother, looking at the vast starry sky.

"This is so amazing! What the hell is that?" said the scholar.

"It's so amazing, so amazing..." Lao Xu no longer had any other words and kept nagging this sentence.

Everyone was shocked by this scene and felt the deepest touch in their hearts. It took them a long time to slowly come back to their senses. We looked carefully for a long time and inferred that there was a huge piece of green jade on the dome as a "screen", reflecting the light emitted by the bronze ancient lamp below, forming a "starry sky" wonder.

"It's so strange here. Whether it's a rosy or a rosy, what's the purpose of building such a strange palace in such a cave?" Ashun's words brought our thoughts back to reality.

Yes, what is the meaning of this palace? After entering the main hall, we began to search. There was no passage or discovery here except the gate that came in. However, the Keyan tribe spent a lot of manpower and material resources to build a high platform to place such a meaningless palace? Even elementary school students would not believe it.

Then there must be some secrets here. The reason why we didn't find it must be that something was ignored. Everyone was silent, trying to discover something.

"Hey, Mr. Xia, do you think the people of Keyan know much about medicine? Sajia refers to Western medicine?" The scholar threw a cigarette and said.

"Fuck, can you be more normal? Haven't you seen everyone thinking about a way out? Can you not make trouble? And Western medicine, why don't you say that the people of Keyan will change their heads? Let's change you a normal one." I said to the scholar.

The scholar almost choked with a puff of cigarette: "Mr. Xia, you are really worthy of being the successor of socialism that the family is beloved by Sajia. With you, communism can be achieved. You are smart, and you really have the point. Did you also find out? The people of Keyan might really do surgery."

"What are you saying? Did you discover something?" I asked.

"Mr. Xia, look, the lights on the walls here. Look carefully, are there any characteristics? Have you been to the operating room? For example, if you have a hemorrhoid or a circumcision?"

"Your uncle! Make a circumcision for you." I just finished scolding the scholar and suddenly understood the scholar's words, "Are you talking about the shadowless lamp?!"

I finally understood what the scholar was going to express. This kid was right. Do the people from the Keyan tribe really understand surgery? The bronze ancient lamps set up in this hall are very distinctive. Each lamp is set up very carefully, and lamps are placed in all directions.

When I said this, the Fourth Master immediately said, "Fourth directions? These are the five elements and eight trigrams!"

Five Elements and Eight Trigrams! Yes, I counted exactly eight lamps, and the positions were exactly in eight directions!

"If it is arranged in the direction of the gossip, what does it mean?" Linglong asked.

"The Mechanism" The Fourth Master walked around for a few times, constantly swaying the bronze ancient lamps on the wall, and then said, "These lamps are fixed and cannot be rotated. Could it be that we were wrong?"

"Second Master, the mechanism does not necessarily rely on rotation or pulling to trigger the switch. What if it is triggered by light and dark?" I pointed to the "starry sky" on the dome.

"Xiao Nan, do you mean by extinguishing some of the bronze lamps?" said the Fourth Master.

"Try it. I think the lamp here should have something to do with the green jade on the dome." Since the "starry sky" on the green jade is the light of the ancient bronze lamp below, then if the bronze lamp is turned off by controlling the situation of the bronze lamp, you may find something.

But how do you determine which light is turned off?

The Fourth Master considered it and said, "The eight lamps here are set according to the directions of Qian, Dui, Kun, Li, Xun, Zhen, Gen, and Kan in the Eight Trigrams, and correspond to the eight gates in the Qimen Dunjia. Among the eight gates, only the Sheng Gate is the only way out. The Sheng Gate is in the Gen Palace and is in the northeast direction."

"That means that only one lamp in the northeast direction is left, and the others are all turned off." The scholar said as he wanted to turn off the lamp.

The Fourth Master stepped forward, buckled his wrist and grabbed the scholar's shoulder, and said, "Don't move! This is not that simple."

The scholar was stunned: "Isn't it the northeast? I just figured it out. Our entrance is south, up, north, and south, and the front right is Shengmen in the northeast direction."

The Fourth Master glanced at the scholar and said, "The eight trigrams are not the upper and lower north. The left one is the green dragon, the right one is the white tiger, the front one is the vermilion bird, and the back one is the black womb. The green dragon is in the east, the white tiger sits in the west, the vermilion bird flies south, and the black womb hangs north. Therefore, in the eight trigrams, the upper and lower north. The gate we entered is the north, and the south is the south in front. Shengmen is in the northeast, so there should be only a lamp on the left rear."
