At the end of the road is a bronze gate inlaid in a stone wall. The gate is very grand, the momentum is extraordinary, it is carved with auspicious cloud patterns, and carved with dragon shape and bird patterns, very exquisite. Lao Xu kept taking pictures and was amazed. I tried to push the door, but it didn't move, it felt extraordinarily heavy.

"The door is not sealed by weight, but by a rolling stone or a log behind it. It's almost impossible to push away from the outside. "Lao Xu has been conducting scientific research in ancient tombs all year round, so he should be familiar with this. He continued: "The ancients attached great importance to the safety of their mausoleums. In order to prevent theft, after the construction of the mausoleum, usually some of the craftsmen who hold the core secrets will be locked in the underground palace. These craftsmen had to seal the gate of the dungeon from the inside with the stones they had prepared in advance. In this way, outsiders will not be able to enter the dungeon again. Later, in the Qin and Han dynasties, craftsmen invented a mechanism in order to survive. When the tomb owner is buried and buried in the dormitory after his death, all the craftsmen withdraw, and then by triggering the mechanism, the spherical rolling stones pre-placed in the dormitory will automatically roll down, and push against the tomb door from the inside, so that there is no need to leave people to operate inside, and there is no need to bury alive to accompany the burial. ”

"That is, we can't open this door no matter what?" The scholar asked?

"Not necessarily. For one-time closed mausoleums, the sealed door can be circumvented by excavation, and some tomb robbers will also use explosives and other violent means to forcibly open the sealed door. For some reasons, such as the joint burial of husband and wife, one party dies first, and the one-time door cannot be sealed. Because after the other party dies, the door needs to be opened again. At this time, it is generally used to seal the door with a mechanism. Lao Xu replied.

The fourth master said: "Let's look first, if there is a mechanism to open the door." The road was so difficult and the design of the mausoleum was so ingenious that the door should be able to be opened. ”

The four of us took a closer look. However, we have touched almost all the places where this door can be reached, and we still haven't found any mechanism to open it.

"Will it be on the stone wall?" The scholar asked.

Our dead horses were treated as live horse doctors, and then moved to the stone walls on both sides. However, there is nothing special about the stone wall at all. We are puzzled, is it really as Lao Xu said, this is a one-time closed tomb door?

"It's a pity that I didn't get the explosives, otherwise I would have used such a hassle?" The scholar began to mumble again.

"This is a valuable legacy! How can you use a bomb? What's the difference between that and a tomb robber? "Lao Xu is very easy-going, but when it comes to archaeology and cultural relics protection, he is particularly sensitive and true.

"The scholar is just saying, don't take it to heart. Such a strange ancient tomb is full of research value everywhere, how can it be destroyed? It's just that this door is in the way, and we have to find a way to open it. Otherwise, sooner or later you will die here. "I'm playing haha, adjusting it to the scholar and Lao Xu.

The fourth master said, since we can't find a way to open it, let's take a rest on the spot first, eat something to replenish energy, and then make a plan.

We couldn't heat it with fire, so we had to drink some water, eat some compressed biscuits, and eat fast food in the wild. As they ate, they talked about how to open the door. Lao Xu said that in order to open this door, we must figure out the principle of locking the door, otherwise it will be a blind man to light the lamp - in vain. Lao Xu is right, we must figure out what mechanism the door is locked on, so that the targeted solution can be successfully passed.

We think that if a door is closed, then locking it is nothing more than the following situations: either there is a mechanism to hold the door from the inside, or it depends on the weight of the door itself, and there is also a situation where the door is jammed by a stone crack. The best way to find out exactly what kind of situation we rely on is to push the door hard, even if it's a small crack, to peek into a thing or two. As the saying goes, a thousand wisdom is not as good as a force. Instead of talking about it on paper, it's better to come to it in real combat!

After a few of us had eaten and drunk, we decided to go up together and push the door together. The four of them stood side by side in front of the door, shouting the trumpet, and exerting force together. But I don't know if the door is too heavy or the thing behind the door is too heavy, anyway, we have used up all the strength to feed, and this door has not moved at all.

"It's not the way, it seems that there is something else." The fourth master said: "If the mechanism behind the door is as expected, the four of us can at least push a little together." Nowadays, it seems that the mechanism behind the door is not simple. ”

Everyone doesn't know what to do, the secret of this ancient tomb is locked at the last step by a door? None of us are reconciled. What's more, going back the way you came is not an easy way to go. Pushing the door just now depleted the physical strength we had accumulated during the break, and everyone had to sit down and slow down again.

I always felt as if something was wrong, and my mind was starting to filter all kinds of information at a rapid pace. There was a hint of excitement in my heart, as if there was an idea that could open up a difficult situation. It's just that my thinking is a little confused, and this idea in my heart is as difficult to grasp as a loach. My heart rippled, and I hurriedly interrupted the discussion between the scholar and Lao Xu with gestures, for fear that this trace of inspiration would run away. When the three of them saw that my brows were furrowed and my eyes were squinting in thought, they did not dare to interrupt my thoughts again.

"! Maybe I know how it works! "I was in the middle of nowhere, and suddenly I grabbed the tail of this little loach. Thinking through the problem all of a sudden, I stood up excitedly. Desperate to prove the right idea. The fourth master, Lao Xu and the scholar also became a little excited when they saw my excitement. The three of them looked at me, waiting for me to unlock the door.

I said, "This tomb owner is not simple. Do you remember the passage where you almost got a patty? At that time, the fourth master said, 'Put it in the place of death and then live', and this tomb is designed according to this principle everywhere. All kinds of designs are the opposite. The more you follow your normal thinking, the more you will die. If you are in that passage, a normal person will definitely run back or panic when triggering the mechanism, but there is only a dead end, and if you look at death as home, calmly wait, you can see the hint on the stone wall, and you can escape. The same goes for this door...".

"Mr. Xia, can you make a long story short? If you think this is a cross talk, just say the way, don't be useless. "When the scholar heard me say that he knew the principle of the mechanism, he couldn't wait to hear the results, and he didn't want to listen to my ramblings at all.

"Comrade scholar, don't worry. Listen to what I'm saying. I continued, "The same is true of this gate." The more dangerous the place, the safer. The owner of the tomb knew that no matter how elaborate the mechanism was designed, it would be difficult to prevent future generations from opening the door, and there would never be a door in the world that could not be opened. So, the owner of the tomb used a bold design - the opposite, if he guessed correctly, the door had no lock at all, and there was no mechanism. ”

The fourth master's eyes lit up, and he smiled slightly and said, "Xia Nan, it seems that you are really smart." This is really the best mechanism. ”

I saw that the scholar and Lao Xu were still a little confused, so I could only continue: "Lao Xu, for an ordinary person, if you want to open a door, what should you do?" ”

"It must have been a door... Yes! I got it, too! Yes, this design is amazing! Lao Xu, under my hint, is obviously also aware of this.

The scholar said, "My day! What kind of dumb riddle are the three of you playing, fooling around here? Hurry up and say it straight, grinding and chattering, like a girl. ”

"Stupid, what Xia Nan means is that this door is not locked at all, because it is not pushed open according to people's behavior and habits, but should be opened!" Lao Xu explained to the scholar.

The scholar said, "Oh! So that's what happened. This tomb owner is really a ghostly clever, like ordinary people, and people like this kind of clever are the least favorite comrades of the organization. ”

In fact, I also had an idea to think of this meaning. It's just that I don't know if it's the right answer, and whether I can open this door or not, I'm not very sure. You can only try it to know if it succeeds. The few of us began to gear up again, and together we went up to prepare to pull the door. When I got to the front of the door, I realized a problem, this door has neither a handle nor a place to grasp, how to start pulling?

The fourth master looked at the door and said can we use a dagger to insert it through the middle of the door, and then use the dagger to pry the door? We had no choice but to try. The dagger was a military dagger bought in a military store, and it was said that it was a batch of goods made by the boss in the army from internal channels, with a sharp blade and a hard dagger. This time I used to pry the door, and I had to rely on it. We inserted four daggers side by side into the crack of the door, and in pairs we pushed them to the left and right. The door was heavy, but it wasn't impossible to open, and it seemed that my guess was correct. Everyone shouted the trumpet and pried it hard, and the ancient bronze door really opened a crack with a creak.

I was excited, shouting for everyone to come on, but the fourth master stopped us. "There may have been no ventilation in the door for thousands of years, and the stagnant air is very prone to bacteria," he said. What's more, this is in the ancient tomb, and the corpse qi and yin qi are very heavy. We'd better not open the door and wait for a while. ”

Lao Xu also agreed with the judgment of the fourth master and said: "What the fourth master said is very reasonable. The door had cracked a gap, and the air was moving fast, and it would be possible to enter it after a while. ”

Then, while waiting for the air to update, Lao Xu told a story that once happened in the archaeological team. When Lao Xu was a student, he interned at a historical research institute. That summer, a farmer dug up an antique in a cellar and reported it to the police station. Lao Xu's institute was ordered to send an archaeological team to carry out rescue excavations. As an intern, Lao Xu was also approved to go to study with him. It was an ancient tomb of the Ming Dynasty, and the archaeologists on the team were dismissive of it. The time span between the Ming and Qing dynasties is small, so there are more cemeteries found in the Ming and Qing dynasties, and they are not as sensational as the ancient tombs of the Qin and Han dynasties. But since we have come, we have to be responsible for history and the people, and excavation is a must, and progress is also very rapid. But when they dug to the entrance of the underground palace, the captain of the team and the experts of the team happened to be drinking in the farmhouse, and those who worked were either hired farmers or a few half-baked interns. No one realizes that danger is coming. At that time, several farmers working in the pit felt a little dizzy, thinking that they were suffering from heat stroke while working in the summer, so they didn't take it seriously. Soon after, these people suddenly fainted, and the interns on the pit also panicked, and several people went down to see the situation, and they all passed out one after another. Lao Xu was sketching the general area of the cemetery with white ash on the pit at that time, and when he saw these people, he was dizzy, so he hurriedly went to the farmhouse not far away to call the teacher. The captain and the experts hurriedly ran over and pulled everyone up in the pit one by one with hooks and ropes. Later, after being rescued by the hospital, these people were out of danger. In addition to such a big event, the higher authorities sent an investigation team. After investigation, it was discovered that the closed air in the underground palace contained poisonous gas, and if it weren't for Lao Xu's opportunity, those people might not be able to do archaeology anymore. In the end, of course, the captain and the specialist were all dealt with. But this experience made Lao Xu more cautious in his archaeological operations.
