Hearing Zhang Gong say that this organ could not be solved, many people panicked again. One particular person shouted loudly, "It's easy to say, who would know we're here?" Even if they knew, no one would know how to come in and save us. ”

As soon as he finished speaking, someone immediately followed, and the man said, "Yes, I'm really going to be trapped here now." ”

"There are a lot of mechanisms in the ancient tomb, how many people know those skills? We definitely can't get out! ”

In this way, you say a word, I say a word, as if the tragic plot in the movie with the theme of tomb robbery has reappeared, and the pessimism spreads rapidly, as if they will immediately become a corpse in the next second.

Seeing this scene, Professor Chen had reached the time when he had to be appeased head-on, so he comforted: "Don't worry, someone will come to save us." ”

As soon as Professor Chen's words fell, Zhang Gong didn't understand the meaning of this sentence, and first asked questioningly: "How can someone come?" I don't know when we're coming, we're all here, and we might think we're working overtime. ”

Professor Chen smiled and said confidently: "I arranged a lot of things in the afternoon, among which I made an appointment with two people to talk about work in the evening. In addition, a lot of police forces have been dispatched from other places, and now it has passed the point of changing shifts, and they all know why they are coming down, so they will also be aware of the problem, and the above few people know the situation below, so they will know our situation immediately after they come. ”

"But how do they know how to get us out?"

"You don't need them to understand, there are only a lot of people here, and if they come with five or six people, they will naturally rescue us."

Zhang Gong was a little confused, and asked in confusion: "Naturally, we will be rescued, what does this sentence mean?" ”

"I thought about it, this trap should have been triggered from the entrance of the cave, and we scanned it from uphill, so we couldn't find a single anomaly along the way; I judged that as long as there are enough people, the lever mechanism below will be triggered, and then the signal will be passed to the high point, and the channel will be switched and changed, then the mechanism below will naturally be opened. ”

"Oh, you're saying it's actually a gravity-sensing trap? That would be easy. ”

Chen Zhijun listened in a daze, and interjected curiously and asked, "Uncle, what is a gravity sensing mechanism?" ”

After Zhang Gong took a sip of water, he replied: "Gravity mechanism, as the name suggests, is a kind of mechanism that will be triggered after reaching a certain pressure, although it is a bit too much to say that the word induction is used here, but this ancient mechanism is indeed worthy of the name of gravity and the principle of lever to the extreme!" For example, if three people stand on it normally, the weight is not enough to reach the predetermined value, and the wonder mechanism will definitely not be triggered, but when a few people are added, after the set value is reached, the wonder mechanism will be triggered. ”

"How does this work?"

"The principle of the bar, this should be the same as the scale bar, if you set a value on the scale bar, you want to warp the scale top, then you must add weight to the scale hook, the principle here should be like this; Here, when our body weight reaches the set value, then one end of the lever will be cocked, and then through the transmission of force, the force here will be transmitted to the mechanism, and the channel will be switched and closed. ”

"Oh, so how do you need to solve it?"

"Fool, you Lao Tzu has already said just now, as long as a few more people stand there, and then walk from there, the mechanism will be triggered again, then we can get out."

"But, uncle, there were a lot of people when you came down before that, why didn't it trigger?"

Hearing Chen Zhijun ask this, Zhang Gong said indignantly: "It was before he was invited to watch the play, and after watching the play, such a situation occurred, which shows that this organ has a device similar to insurance, and it is manually operated, and what we are experiencing now is all given by those people." ”

"Those people? Grave keepers? ”

"Yes."

Listening to Professor Chen and Zhang Gong's in-depth analysis of the mechanism, everyone was silent. Zhang Gong and the others took out chocolates, compressed biscuits and water from their backpacks, and after distributing them to everyone, the group sat two meters away from the machine, eating and chatting.

During this period, Professor Chen's eyes have been quietly staring at a person, and he feels more and more suspicious, and finally, he finally made an amazing discovery!

In order to divert everyone's attention and further ease the mood, Zhang Gong told a true story at the strong request of Zheng Suo and others.

The story takes place in the early summer of 2002 one morning, a farmer was watering the ground, suddenly found a small hole in the field, the water flowed in, he quickly shoveled some soil from the side, trying to plug the hole, but the hole in the water flow, bigger and bigger, finally, the ground slowly collapsed, soon formed a large pit with a diameter of about 3 meters, frightened he quickly went to pull the electric switch, back to call the village chief. A village of people soon gathered around, and some old people said that there was once a legend here that a certain general of the Liao Dynasty was buried here. Due to the superstition of the people in the village, no one dared to go down to see what was going on, so the village chief called the police. Soon, it alarmed the city's cultural protection department, and after they went in for a preliminary investigation, they confirmed that it was a Liao tomb, and the structure was very special. Feeling unsure, the local government applied upwards. By the time we rushed over, the water had been drained and the silt had been cleared, and everything was done professionally. When digging to the corner of the King Kong Wall, there will be controversy, some people suggested that they directly smash a hole from the top and go directly into it, on the grounds that it is fast and efficient, not a waste of time, and some people advocate digging out the entire tomb along the King Kong Wall, so as to better protect and excavate the tomb. Professor Chen has always been against barbaric excavations, so he made a decision on the spot and said: "Since we are here, then this tomb must be excavated intact, if you want to excavate in a barbaric way, then I will immediately take the team members away, and after we leave, you can dig as you like." That aura immediately calmed everyone. Seeing that everyone was silent, he pulled me out of the cemetery and asked me to stand on a high place to see the feng shui trend of this tomb and see if I could determine where the tomb gate was. So I climbed to a big tree, looked at the cemetery, looked at it a few times, and combined with the compass, I found that the tomb was not facing due south, and the angle was 45 degrees off. I wondered at the time, how could there be such a tomb? So I thought, could this be an octagonal tomb? Over the next two days, I was able to test my idea by expanding the work area, and I found an entrance between the two corners on the south side. The entrance was blocked with volcanic rocks, and it was hard to dig it up. So our comrade Wang came up with a method, let people buy a lot of vinegar, and then slowly brush the gaps in the stones with a brush, and seal them with plastic sheets, and after staying like this all night, the next morning, he used a shovel to easily pull out the door sealing stone to the crack, and then with an iron hook to reach in, pull back hard, in the "pop" sound, the brick was pulled out.

As soon as he finished saying this, Team Fan interrupted: "Zhang Gong, it seems that I really heard a 'pop' sound somewhere just now. ”

As soon as Zhang Gong heard this, he immediately turned his head and sent the flashlight two meters away, and after this photo, he immediately shouted excitedly: "The passage is open, someone has come to save us, hurry out!" ”
