Professor Cao nodded approvingly. It seems that he has learned real things as a student.

Yang Xiaobao couldn't understand the meaning of the professional terms in the second group at all. He couldn't restrain his curiosity and asked Mei Zi, "what's the matter?"

Meizi explained: "huangchangticuo is a kind of tomb situation, which is a frame structure made of cypress wood around the outer chamber of the emperor's mausoleum. The coffin was surrounded by a circle of wood walls with a roof, like a house. Most of them were found in the Han Dynasty, and they rarely appeared after the Han Dynasty. This is a kind of tomb situation of the highest standard, which can only be used after the death of emperors or princes. "

Yang Xiaobao understood. This is the same reason that only the leaders of the county Party committee can match Santana. The issue of rank is a means to show identity and honor!

Professor Cao added: "after we found this, we can basically confirm that it was a Han Dynasty Prince buried in it, which has quite high research value."

After a while, the staff reported that the air in the cave was not enough to pose a threat to the human body.

Professor Cao excitedly ordered: "take the safety belt and the sliding rope. I'll go down and have a look myself."

Yang Xiaobao was stunned. The old man was really desperate. The cave is more than ten meters deep, which is equivalent to the height of a four story building. Because the tomb passage is too tight and narrow to put a ladder, it can only be hoisted in with a rope. Even if young people are allowed to do the work, it will take a lot of effort. What's more, God knows if there are any secret devices in it?

Meizi also dissuaded her teacher: "teacher, you are old, and you have to take the overall situation. I'd better lead a few people down to have a look first."

Professor Cao is right after thinking about it. There must be someone on the ground to command by remote control. If Mei Zi is given the job, she is still a little inexperienced.

"Then you take some quick young men down. You must be more careful and pay attention to safety."

Meizi nodded and agreed, and immediately ordered a few more people. Several men began to arm.

Safety belt, safety helmet, gas mask, miner's flashlight, these people are really a professional.

Yang Xiaobao gapes at Mei Zi, who is equipped. In front of her, she is just another person. Apart from the tight waist and slightly fat hips, there is no more feminine features.

... I didn't expect this girl to have a good figure.

"Young man, do you want to go down and have a look? It's a lifetime opportunity. " Professor Cao asked Yang Xiaobao excitedly.

Yang Xiaobao is really curious. He wants to go down and have a look. But think of a rotten tomb robber's body in the cave... Forget it, it's not disgusting enough.

Mei Zi led several archaeologists to hang ropes down to the cave. Through the surveillance camera, Yang Xiaobao deliberately saw that she and several staff members tied the tomb robber's body with ropes and hung it up.

It's live. It's more exciting than a horror movie. Especially when she saw the archaeologists lifting the corpse, Meizi holding a rope and arms around the back of the corpse, it was like holding the dead ghost, and disgusting Yang Xiaobao almost vomited out.

This girl's psychological quality is so powerful! After she comes up, no matter how beautiful she is or how good she is, I have to stay away from her... Yang Xiaobao thought.

The body of the tomb robber was dragged up and sent to the tent for professional study. The archaeologists in the cave also entered the main tomb passage, lined up and moved forward carefully.

Meizi's performance makes Yang Xiaobao look at her with new eyes. As the only woman, she has the courage to walk in the front all the time. Through the lens of her helmet, you can see the dark graveway.

Yang Xiaobao was so frightened that he didn't dare to go out. Professor Cao noticed his nervousness and said with a smile, "don't be so nervous. Although Xiaomei is young, she is my most proud student. I have seen many ancient tombs with her in the past two years. Among the following people, she is the most experienced, so she is ahead of the others. "

Yang Xiaobao was so impressed that he turned his lips and said, "great. It's rare for a girl to have the courage to practice like this..."

Yang Xiaobao's voice did not fall, at this time the change suddenly happened!

One of the archaeologists behind accidentally touched the wall with the palm of his glove, and there was a loud bang. A huge stone appeared at the main tomb crossing somehow. At this time, Meizi, who was walking in the front, happened to be walking in the front. Just stepped into the entrance of the tomb.

Through the lens, we can see that she is very quick to respond, and she has escaped the misfortune of being pressed by the boulder as soon as she pours forward. But just as the rock fell, the signal went off

Professor Cao was shocked and immediately gave an order: "everyone return to the ground immediately!"

Fortunately, several archaeologists began to be pulled up in panic. Excited, Yang Xiaobao grabbed old man Cao's arm: "what about your students? Let her stay down by herself? "

Professor Cao's face is very blue. Meizi is his most proud student. It's not him that worries about such an accident? But what can be done? The signal can't be connected. No one knows what happened to Meizi below. It doesn't help to have those archaeologists down there.

The archaeological scene was in a mess, and Professor Cao urgently called all the people together to discuss countermeasures.

A group of people talk about everything.

"The most important thing now is to find a way to restore the signal, otherwise we have no way to know what happened in the graveway."

"She's a girl's family. Is she nervous when she's alone in the graveway?"

"Xiaomei is my best student. She has excellent psychological quality. Don't worry about it." It's Professor Cao speaking.

"But the oxygen in the graveway is very thin. It's hard to say how long the gas mask can last. Besides, it's getting dark, so the rescue is more difficult."

A group of people were full of gossip, and they couldn't come up with an effective way to save people.

Yang Xiaobao was very worried. At this time, he had only one idea in his mind: the next one is a living man, a young girl

Professor Cao and they finally came up with two plans.

First, break down. Open a hole directly from the big stone blocking the graveway to rescue Meizi. It takes a short time and can be done in a few hours, but the risk is also great. God knows if breaking the big stone blocking the door will trigger other organs in the tomb passage?

Second, we should speed up the construction progress and use all our strength to start the excavation. It is expected that the tomb passage can be dug out in five days. This is safe, but only if Metz can live to that time without water and food.

It was Professor Cao who made the final decision, but he couldn't make up his mind for a moment. No matter which plan, it is extremely dangerous for Meizi.

At this time, the situation met by Meizi was a bit similar to the mine disaster, but it was worse than the mine disaster. After all, there were no man-made lethal mechanisms in the mine, so every minute she stayed underground, she was in more danger.

Yang Xiaobao put forward his own opinion to Professor Cao: "in addition to what we discussed, I have come up with a way, which can be regarded as the third scheme."

Professor Cao: "tell me about it?"

Life matters, not to mention the trapped students. At this time, Professor Cao is willing to accept any suggestions, as long as Mei Zi's safety can be guaranteed.

"Everyone saw the body of the grave robber. The body was found at the entrance of the cave. He died on the way back. This shows that the protection mechanism set up by the owner of the tomb is not without loopholes. At least the unfortunate thief once entered the passage of the tomb. "

Professor Cao's eyes brightened. The starting point of Yang Xiaobao's idea is really original, and it is also true in theory.

Yang Xiaobao then said: "since the tomb robbers of many years ago can do it, why can't we make the same hole and save people first?"

Professor Cao smiles bitterly and tells a real case to Yang Xiaobao.

"During the excavation of the terracotta warriors and horses, there was a tomb No. 6 of Duke Qin. In the process of excavation, archaeologists found that the tomb was excavated by the tomb robbers. However, dozens of corpses were also found in the cave, all of which belonged to the tomb robbers, indicating that none of them succeeded. Even one of the caves was blasted out by tomb robbers with explosives. It was 19 meters deep and led directly to the coffin. But this brave grave robber finally fell on the last pass. Do you know why? "

Yang Xiaobao hesitated: "why?"

Professor Cao said with a wry smile: "because explosives can open the earth, but they can't open the coffin. The coffin of Qin Gong's tomb No. 6 is basically the same as the one in front of us. They have a common name, Huang Chang Ti CuO... "

The specially treated cypress is even harder and more tenacious than stone, so it can't even be blasted by explosives.

Yang Xiaobao: "impossible! I firmly believe that there must be shortcomings in this tomb, and there must be a way to solve the problem of Huang Chang. Otherwise, among all the stolen tombs of the Han Dynasty, none of them has a cypress coffin? "

The reason why Yang Xiaobao is so determined is that he knows very well that the treasures found on the tomb robbers must have been brought out from the inside of the coffin. This unfortunate thief must have gone in! Now that grave robbers can get in, now that people have mastered more techniques, they can certainly get in.

"Professor, let me have a try! Since there are grave robbers who can enter the tomb and steal cultural relics through the hole dug out overnight, I believe I can do it myself. "

Professor Cao has some ideas. If others say it, he will not believe it. But if Yang Xiaobao says it, he will have some credibility. After all, he has a unique family tradition.

Professor Cao thought about it and asked Yang Xiaobao cautiously, "how sure are you?"
