Professor Chen looked at the east side of the mountain and said to Vice Mayor Zhao and Sun Bureau: "Mayor Zhao and Sun Bureau, I personally predict that the entrance is on the east side, that is, the position of Tie Hua in the tunnel is a little bit easter, I hope to do a technical defense there, and then arrange some police forces near the entrance in the rear, I am afraid that someone will come from the east and above, so I hope to be on guard there." ”

When the Sun Bureau of the Public Security Bureau heard that the location of the entrance had been roughly determined, he was surprised and said, "The location of the entrance has been determined so quickly?" He really deserves to be a master from the capital. The armed police will arrive in the afternoon, and they will arrange four in the tunnel, a group of two, 12-hour rotation, responsible for your work and work safety, and then follow your progress to arrange another 6-8, 24-hour armed guards. ”

"If it goes well, you can reach Yongdao through the entrance at night, and then look at it, it is easy to find the entrance, but it is a complicated process to pass through Yongdao."

"Oh, what's in the road? Mechanisms in the movies? ”

"Well, I don't rule it out."

"Is that dangerous? How to rule it out? ”

"This first depends on what kind of institution it is, according to different institutions, you can also roughly judge the purpose and age of this, this Professor Zhang is an expert."

"Admire you! What you need us to do, we will resolutely cooperate! ”

Vice Mayor Zhao looked around, still not understanding why he was sure where the entrance was, so he asked, "Professor Chen, I'm just curious, how can you be sure where the entrance is?" ”

Professor Chen smiled, took out his mobile phone and flipped through the photos he had just taken, showed them to Vice Mayor Zhao and Director Sun, and asked, "Try to see if you are related to this industry, you see, are there any details?" ”

Vice Mayor Zhao looked at it and said, "I really can't see any difference." ”

Sun Ju took the mobile phone from Vice Mayor Zhao's hand and looked at it, and after a while, he seemed to see his eyebrows, and said excitedly: "Professor Chen, is this place, this seems to be a place like a platform." ”

"Sure enough, he is the director of the Public Security Bureau, and his eyesight is good, but judging from a place with a similar platform, there are many coincidences, and many places on the mountain will be similar to this. I'm sure the approximate location is the same as your opinion on this point, and there is another point, that is, the color of this vegetation is different, and it is obviously much darker, that is, this may be artificially planted, and the purpose is very likely to cover the entrance, combined with the location of the iron birch in the tunnel, so it is basically determined. ”

After listening to Professor Chen's explanation, Vice Mayor Zhao shook his head and sighed: "Sure enough, archaeology is not done by ordinary people, it requires great talent. ”

Professor Chen joked: "Haha, if I take a compass and pretend to be in this comparison, can I pretend to be Mr. Feng Shui?" ”

"In that case, you're a feng shui master!" After everyone laughed, they stood aside and watched the supplies be lifted up through the crane on the bridge.

In a few moments, the Civil Affairs Bureau sent tents and other materials to the tunnel, and set up headquarters and shelter in the tunnel according to Professor Chen's request.

With the arrival of materials one after another, Professor Chen's entourage also began to debug all kinds of equipment in the tent in the tunnel, and everything was in an orderly and silent way to tell everyone: the excavation work will start immediately!

Time passed quickly, and the local archaeologists came, the TV station also came, and the various technicians responsible for implementing Professor Chen's request also came. Under the arrangement of Lei Tongren, Lao Ma and a group of workers also began to clear weeds from the edge of the tunnel, and used shovels and pickaxes to level out a simple road more than one meter wide step by step.

Professor Chen gathered everyone together for a simple meeting, and after the personnel were grouped and arranged, the excavation work officially began.

The archaeological team, led by Professor Chen, carried backpacks and skillfully advanced on the improvised road, followed closely by local archaeologists and cameramen, and soon arrived at the predetermined location.

There are still more than 5 meters away from the predetermined location, Professor Chen stopped in front of the mound in front of him, just now the simple road that the old horse and they built is over, Professor Chen squatted down and took off the backpack from the back, took out a delicate small shovel from it, and cleaned up the gravel under his feet, Feng Weiguo immediately squatted down when he saw this, and looked at Professor Chen's movements and asked: "Professor Chen, is this the roadbed of the year?" ”

"I'm not sure now, it's all gravel and dirt, we'll find out later."

With the movement of the small shovel, the original gravel and dirt were cleared, and the whole stone slab was underneath.

"This should be the road that the ancients built to go up the mountain, wait a while, and then see how big this stone slab is."

After speaking, Professor Chen continued to move, and Ma Kai, the assistant on the side, also joined the ranks of cleaning up the floating soil and rubble at the same time.

In less than two minutes, a 30-centimeter-wide, 1.2-meter-long bluestone slab came out.

"Now assuming that this road was 1.2 meters wide back then, it is not easy to transport something in such a steep mountain, unless it is a small thing," Professor Chen stood up and said to everyone after saying to Feng Weiguo: "From now on, everyone pay careful attention to your feet and surroundings, and don't miss any details." ”

After that, everyone continued to search and move forward. Suddenly, archaeologists in one place shouted, "This is a discovery!" ”

Professor Chen hurriedly went over to take a look, and it turned out that it was a square hole cut in the mountain, about 20 centimeters long and wide, and about 50 centimeters deep.

Professor Chen called Zhang Gong to look at it and asked, "What do you think?" ”

"This artificial chisel mark is obvious, it should have been used for cranes back then, this one is flat, there should be such chisel holes below and above, but the angle will be different."

A local archaeologist asked Zhang Gong curiously: "There were cranes in ancient times?" What is it like? ”

"With the existing discoveries, China is the world's earliest country in the invention and use of machinery, in the Zhou Dynasty, the principle of lever was used in many ways, and the combination of the principle of lever and simple pulley was found much earlier than the Greek, they are 330 BC, we are 1046 BC, it is not a street problem to throw them, but the record is quite small; The ancient cranes were very simple, with a triangular bracket suspended from a log on the outside, pulled by a rope, and subsequently developed into multiple groups for changing direction,"

Before Zhang Gong, a physics master, finished explaining, he was interrupted by the cry of "another one was found", and this discovery was four meters away from the discovery just now, and the angle was the same.

Feng Weiguo asked: "Zhang Gong, if this is what was used as a crane back then, that is, the volume of things transported inside by lifting back then will not be small, is it possible to determine the scale of the inside?" ”

"This can't be determined, it can only be said that the objects lifted that year were relatively large and inconvenient to lift. But in terms of quantity, this is unknown, and you will only know once you go inside. ”

After that, everyone continued to look for new discoveries. Sure enough, two more holes full of dirt were found on the slope below the two places found at a distance, and the positions corresponded to the two above, the only difference was that the angle of the holes was diagonally upward. So far, we can fully confirm the purpose of the hole, and everyone is getting excited, and they continue to carefully look at their feet and sides.
