Chapter 488 The underground palace detection results are out! (It’s still nine thousand chapters!!!)
2 hours and 18 minutes.
The time limit given by Jiang Chenggu quickly spread throughout the entire scene after being informed by Xu Yun.
See this situation.
The speed in everyone's hands couldn't help but speed up a lot - this situation can be said to be a real race against time.
"Where's the power cord? Xiao Li, give me another power cord!"
"Hurry up and put the antenna up! Have you measured the wind strength?"
"The wind force is level 2, which is quite normal!"
"The UAV team is ready, the remote sensing target will be in the sky within five minutes!"
"Check everything in the car again. Don't leave anything behind. Why is there a fishing rod in the trunk?"
"Oh, I stuffed that in before leaving from the headquarters. Brother Huang, wasn't I thinking that there was a lot of water in the Yongling Underground Palace? Maybe it would have its own ecosystem with fish? Don't throw it away when you encounter a puddle. If you have two rods, can you still call yourself a fisherman?”
"."
After a while of busy work.
8:15 am.
The remote sensing team members on the two remote sensing vehicles were notified and released the remote sensing drone first.
There are a total of twelve remote sensing drones in this batch, all equipped with standard remote sensing detection equipment - the kind that can transmit signals back and forth.
Their main purpose is simple, which is to confuse people as mentioned before.
It can be regarded as a means to confuse those melon-eating parties, and it can also satisfy the psychological needs of the melon-eating parties to watch the excitement.
Just like road construction in reality.
As soon as you put up the shed and swing the excavator out, the machine will make a clanging sound.
Basically, not many people will explore whether it is actually building roads or quietly tinkering with other things.
After flying into the sky.
The twelve drones quickly began to fly towards the Chongmen area.
From a geographical perspective, Yongling is located due west of Deling and due north of Jingling.
In other words.
The three mausoleums of Jingling, Yongling and Deling form a standard L shape.
Therefore, when the Ming Tombs scenic area is completely closed, there will definitely be no tourists in Jingling and Deling.
Only the west and north positions of the Yongling Chongmen can accommodate people.
In fact, this is exactly the case.
At this moment.
In the tourist resting spots on both sides of the Yongling Main Gate, hundreds of tourists were sitting, ready to eat melon and watch the excitement.
After all, the Ming Tombs, as a well-known scenic spot around Yanjing, receive a high number of tourists on weekdays, with the average number of visitors per day being in the thousands or tens of thousands.
For example, the May Day holiday in 2021.
The total number of visitors to the Ming Tombs is as high as 96,000, which is only a little less than the 108,000 in the Old Summer Palace. It ranks among the top ten in Yanjing.
In addition, Xinhua News Agency just broke the news about the excavation of Yongling Tombs, which suddenly raised the popularity of the Ming Tombs to a higher level again.
Even men like Wang Tong, a man in science and engineering, were attracted by the news, let alone other tourists.
Many people simply came to Yongling today. Although they now learned that the Ming Tombs were not open to the public today because of the exploration of Yongling, these people became more and more interested.
Some people chatted in twos and threes, while others started the live broadcast alone, and the chatter seemed lively.
"Hey, the last time I came to the Ming Tombs was when I was in college. I haven't seen you for twenty years in the blink of an eye. The Ming Tombs have changed a lot. In my impression, there used to be a wall there."
"Remote sensing exploration should start soon. I don't know how long it will take to start digging the underground palace this time."
"I guess at least two more chapters."
"Thank you Zhang Ying, who loves me the most, for the gift of love. What? How much does it cost to do a tweet for me?"
"Emperor Wanli buried in Yongling was very controversial in history. He was a dissolute man. Do you know that Baofang was built by him?"
"What? Brother, the Leopard Room was built by Zhu Houzhao, and buried in Yongling is Emperor Jiajing"
Just when everyone was chatting happily.
Suddenly someone pointed in the distance and said loudly:
"Look, drone! Has remote sensing mapping started?"
Hear this.
Swish——
The scene fell silent for a moment.
Everyone turned their heads and looked to the east where the person was pointing.
Sure enough.
At this time, four black drones were flying leisurely out of the Chongmen area to the east, and they were much larger than ordinary drones.
If your eyesight is good enough, you can also see a device on each drone flashing red light.
See this situation.
The melon eaters who were originally sitting in their seats stood up one after another and poured out of the corridor of the rest point.
Many children excitedly waved their hands towards the drone and jumped up and down, as if they were using the drone as a camera.
More people took out their mobile phones and took videos.
"Boys, are you watching? That thing is a drone!"
"Mom, have you seen the little black dot in the sky? Surveying and mapping has begun!"
"Sons in the dormitory, my father wishes you a happy Qingming Festival in front of the grave of the Ming Dynasty emperor~"
Tell the truth.
Drones are actually not uncommon devices in life. Drones can now be seen in many places or activities.
But after it was associated with the word Yongling, its nature suddenly became different.
While the melon eaters were filming the video.
in the crowd.
Several men with ordinary looks and carrying small hiking bags like many tourists looked at each other and walked to a deserted corner in a tacit understanding.
The leader was a tall middle-aged man. He pretended to be a gathering of smokers and handed a cigarette to a young man in blue with glasses, and asked in a low voice:
"How's it going? Have you got any results from the detector?"
The young man in blue pulled the shoulder strap of the mountaineering bag twice and nodded:
"Well, some of the feedback electromagnetic waves from land surface remote sensing have been intercepted, and the converted radiation calibration conforms to the RSP remote sensing model. This is a topic being studied by the Electromagnetic Information Space Laboratory of the University of Science and Technology of China."
"In other words, there is nothing unusual about this detection?"
"I think so. If it is to test the actual effectiveness of the RSP remote sensing model, the time will be explained - the results are ready to be published, just like the article doi.org/10.1038/s41586-021-04315-3 Same.”
I heard what my companion said.
The middle-aged man nodded slightly:
"Very good, then we can go back and file a report. The rewards will be divided according to the old rules."
Then he raised his head and glanced at the drone not far away, suddenly thought of something, and added to the speaker:
"By the way, Xiao Zhou, we captured the electromagnetic wave signal of the drone. We won't be discovered by those inside, right?"
When the young man in blue named Xiao Zhou heard this, he smiled confidently:
"Don't worry, it won't be discovered. Unless they are equipped with a work trace recorder, the receiver must only operate in one direction - and the work trace recorder is military equipment. You think it may appear here. ”
"If you ask me, this matter is purely due to you and the superiors being cautious. It is just an ordinary surveying and mapping from beginning to end."
The tall middle-aged man glanced at Xiao Zhou and slapped him on the back of the head:
"You're the only one who talks a lot. Okay, let's close the team and let Pangu Seven Stars help themselves. I'll treat you!"
And just a few minutes after this group of mysterious 'tourists' left.
Surveying site.
Jiang Chenggu quickly came to Academician Pan and Xu Yun with the engineer Ma who was responsible for network security whom he met at the meeting:
"Academician Pan, Dr. Xu, you guessed it right."
"According to the work traces and the recorder detection, someone outside the heavy door did intercept the feedback signal of the remote sensing detection equipment. Fortunately, we took extra precautions."
Academician Pan glanced at him, his face looked very calm:
"As expected, this is something that can be done across the sea."
Xu Yun on the side also nodded slightly.
Although due to publicity needs these days, Haidian often shows an ugly and stupid image in China.
But let’s be honest.
It's really ugly across the sea, and they do all kinds of dirty things, including stealing oil and smearing others.
So stupid.
Many times it's not necessarily true.
If the other side of the sea is really stupid, the pressure on the rabbits now is far from being so great.
In many matters, the think tank across the sea is not a free-for-all,
Take this excavation of Yongling, for example.
Although the project seems to have no sensitive color from beginning to end, it is just an ordinary excavation project.
But the project proposal is a red text document after all, and it is entirely possible for the other side of the sea to use some detection methods other than satellites.
Anyway, just spend some money, the funds are used for this purpose.
There are many similar examples. People with malicious intentions were caught when the No. 2 Pit of the Terracotta Warriors and Horses was being excavated.
Therefore, after prior discussion, Academician Pan, Jiang Chenggu and others finally made a more reasonable plan:
The remote sensing module of the drone is equipped with a set of remote sensing models from the Electromagnetic Information Space Laboratory of the University of Science and Technology of China to complete the trick.
This remote sensing model is relatively advanced in theory, and at the same time, the signals are easy to identify and can be easily captured and intercepted.
This way.
The admission of Academicians Pan and Xu Yun has become reasonable, and the confidentiality of the gravity gradiometer has also been enhanced simultaneously.
Of course.
It needs to be explained.
Academician Pan and Jiang Chenggu are not worried that the gravity gradiometer will be copied after being leaked. It has been mentioned before that the real core of the gravity gradiometer lies in the mapping module and structure. This was Xu Yun's breakthrough through awarding drawings.
That is to say, even if the other side of the sea knows that Pangea particles can be used for instrumental surveying and mapping, it is still difficult to imitate them.
Academician Pan. In other words, what the higher-ups are really worried about is that the existence of the gravity gradiometer itself is known to the outside world.
If the other big countries across the sea know that the Rabbits have developed a gravity gradiometer, they will inevitably increase their military expenditures significantly to upgrade nuclear submarines.
This way.
Unless three wars break out immediately, over time, the deterrent effect of the gravity gradiometer may be weakened as the opponent's technology improves.
So for the rabbits.
The gravity gradiometer is a vital weapon.
It is just like Mao's nuclear submarine breaking the ice and surfacing. It is not that it cannot be made public, but it must be used at an appropriate time, otherwise it will be a waste.
Give an example.
If someone demonstrates on the grounds of "visiting" a sensitive area, play some games through diplomacy.
If only the rabbits had gravity gradiometers
Then there is no need for force to deter them. The rabbits only need to lightly announce the location of the nuclear submarine on the other side of the sea in the Arctic. Then the outcome of this matter will probably be different.
After the Damao nuclear submarine broke through the ice and surfaced, the other side of the sea languished for seven months.
True.
Some days have passed since the 4V incident, so there is no need or meaning to discuss it again.
But now the rabbits have the gravity gradient meter. If something similar happens again in the future, it will be fun to watch
Anyway, Xu Yun was looking forward to that day.
all in all.
The reason why the gravity gradiometer is kept secret has nothing to do with technical reproduction, but because the deterrent effect will be reduced after it is made public.
Therefore, until then, strict precautions must be taken to prevent information from leaking.
Then Academician Pan thought for a while and asked Jiang Chenggu:
"By the way, Director Jiang, have those people who intercepted the signal been locked in?"
Jiang Chenggu nodded and patted Engineer Ma next to him on the shoulder:
"Don't worry, in less than a minute, the comrades from the Internet Security Bureau have dug out their family trees."
“These people are all travel-related video bloggers or practitioners, as well as electronic device enthusiasts.”
"The leader among them is called Chen Weizhi. His profession is quite special. He runs a noodle shop next to Beijing Normal University."
"The bosses just wanted to play a long game to catch big fish, so they didn't take any action against them for the time being and let them go back."
Talking and talking.
Jiang Chenggu suddenly smiled, as if he thought of something interesting:
"However, although they were not controlled immediately, there must still be necessary surveillance."
"For example, Chen Weizhi's noodle shop. If nothing else happens, his noodle shop will become the canteen of the confidentiality department in the future - it is said that the comrades in the confidentiality department are already making reports and trying to allocate a certain amount of funds. After all, eating noodles has to add something. Isn’t it braised egg and small intestine? ”
Academician Pan:
"."
Then Academician Pan paused, looked at the time, and asked Jiang Chenggu:
"Director Jiang, it's almost time. Should our equipment be ready?"
"Oh, I was just about to tell you."
When he got down to business, Jiang Chenggu’s expression was solemn:
"Is the pre-commissioning of the gravity gradiometer completed?"
The debugging of the equipment was the responsibility of Xu Yun, so he quickly gave a reply:
"Director Jiang, the gravity gradient instrument was prepared five minutes ago and is ready to take off at any time."
Jiang Chenggu nodded, glanced at Zhang Ziang, who was conducting data mapping on the external buildings of Yongling, and said:
"In that case. Dr. Xu, let's get started."
"Received!"
Xu Yun said yes to Jiang Chenggu, then turned to look at Zhang Han beside him:
"Sister Zhang, you can send the equipment to the sky."
Zhang Han was ready when several people were talking. Now that he received Xu Yun's instructions, he immediately pressed a button.
After a while.
Two F-500 central axis drones flew into the sky at the same time.
Same as the previous small drone.
One of the two F-500 central axis drones is also equipped with normal remote sensing equipment to confuse the line of sight.
At the same time, its height is more than 300 meters higher than the one carrying the gravity gradiometer.
Other than that.
This time the gravity gradiometer is also simply packaged on the outside. It looks like an area array push-broom scanner - an area-array push-broom scanner is a relatively large type of optical remote sensing instrument. The popularity is also very high.
For example, in the documentary "A Journey to Hundreds of Mountains and Hundreds of Rivers" shot by the CCTV Documentary Channel, a considerable part of the footage was shot using an area array push-broom scanner.
You can say that this thing is used for data detection, or it can be said to collect material for documentaries.
After all, for such a special project as the Yongling Excavation, it would be normal to film a documentary from beginning to end, but it would be abnormal not to film it.
Other than that.
In the last remote sensing vehicle, there is an information team of five people who are constantly observing changes in signals in various bands in the surrounding area.
Assisting them is a satellite located above Yanjing called Cangqiong 3.
This is a geostationary electronic reconnaissance satellite. Its performance is benchmarked against the Mentor, also known as the advisory satellite, across the sea.
It has a space-based wide-area surveillance system that can monitor thousands of ground signal sources at the same time.
If necessary, electronic signals such as radar, missile telemetry, mobile phone signals, and communication broadcasts in low northern latitudes can also be searched.
What, why low northern latitudes, you ask?
Want to watch the Vietnam Football League?
no way.
Although rabbits are all stable
Then under the gaze of everyone.
The two F-500 central axis drones flew higher and higher.
After reaching a height of one hundred meters.
Among them, the drone carrying a true area array push-broom scanner began to change direction and gradually moved outward, while continuing to increase in height.
After a while.
There was a faint sound of shouting near the heavy door.
Obviously, the melon eaters are excited again.
The drone carrying the gravity gradiometer stopped at a hundred meters and began to circle around Baocheng.
Of course.
Xu Yun and others have already conducted rigorous calculations on the data and specific processes required for the entire surveying and mapping process.
There are strict and clear plans for the drone's altitude, flight speed, and which area it will stay in for a longer or shorter time.
For example, the exact height of the drone is 114.514 meters, the speed of the circle is only 15 kilometers per hour, etc.
Two minutes later.
The drone, equipped with a gravity gradiometer, stopped at the first area marked in advance and began surveying and mapping.
Taking advantage of the break in surveying and mapping.
Xu Yun also introduced Jiang Chenggu and Zhang Ziang, who had just completed ground data collection:
"Director Jiang and Academician Zhang, both of you should know that the state has actually conducted many microgravity remote sensing surveys of Yongling a long time ago."
"Although the relevant surveying and mapping accuracy is very low and no information about the tomb has been collected, two things are certain."
"The first is the accumulation of water in the Yongling Underground Palace. The height of the accumulation is about 6.5 meters, which is close to the top of the tomb."
"The second is that although the underground palace of Yongling is the second largest among the Thirteen Tombs in terms of structure, its layout is the same as that of Dingling."
Jiang Chenggu and Zhang Ziang nodded at the same time.
The first point Xu Yun said is a commonplace and does not need to be elaborated.
As for the second point
This is the information I learned after joining the project team.
Jiajing was the second longest reigning emperor among all Ming emperors, and had enough time to repair his tomb.
Therefore, Yongling is also the second largest tomb among the Thirteen Tombs in terms of organizational scale.
However, according to remote sensing mapping.
The Yongling Underground Palace is large, but its layout is similar to Dingling:
It is a pattern with the character [A] minus the bottom horizontal line.
Among them, the left, upper, and right parts of the word [A] after removing a horizontal line are palaces. The upper one is called the apse, and the ones on the left and right are called the left and right side halls.
At the same time, there is a small hall behind the left and right side halls.
The middle horizontal line is the aisle, and the vertical line is divided into three tomb chambers.
"According to the earliest microgravity detection results, the left side hall is closest to us."
on the ground.
Xu Yun pointed to the real scene of Baocheng in front of him and said:
"The back hall is located to the east of us, which is on our left hand side, and the front hall is on our right hand."
"Among them, the coffins of Emperor Jiajing and the three empresses Chen, Fang and Du are located in the apse - this is a rule of 'etiquette' and does not even need to be supported by detection results."
Then he paused, took a floor plan from Zhang Han, continued to draw and said:
"So based on the distribution of these nine tomb chambers, we formulated nine surveying and mapping stopping points to ensure that the first floor of the Yongling Underground Palace is clearly detected first."
Hear the words ‘first level’.
Jiang Chenggu looked up at Xu Yun but said nothing.
Mentioned a long time ago.
At present, people in the world have two different views on whether the "Yongle Dadian" exists inside Yongling.
Those who support the existence of "Yongle Dadian" in Yongling are divided into three small factions:
The first is that Jiajing did not have separate tombs, and the "Yongle Dadian" is in these nine or eight tombs except the apse. Let's call it the Adventist.
The second theory is that Jiajing opened a secret room on the same floor of the underground palace to store the "Yongle Dadian" separately. Let's call it the salvation faction.
The third type is.
Jiajing did not dare to destroy the inherent structure, so he dug a second floor below the underground palace to house the "Yongle Dadian" - this part is considered a survivor.
Tell the truth.
All three factions have a point.
The total number of "Yongle Dadian" is 10,000. According to Ming historical records, each volume is 50 cm long and 30 cm wide, but the thickness is unknown.
Assume that each volume is two centimeters thick.
Then 333 volumes of "Yongle Dadian" can be placed per cubic meter, and only about 30 cubic meters are needed to store 10,000 volumes.
A modern two-bedroom apartment has an area of almost 100 square meters.
In other words.
Theoretically, as long as the pile is as high as a quarter of Pandora, this room can hold all the more than 10,000 volumes of the Yongle Canon.
Although if buried according to standard etiquette, there would not be such a large vacancy in the Yongling Underground Palace.
However, during the excavation of Dingling, an unusual discovery was made:
The entire left side hall of the Dingling underground palace is completely empty.
This issue is still very controversial so far, and the Advent party’s explanation is as follows:
The left side hall was originally used as a tomb for the burial of concubines. After Zhu Qizhen, Emperor Yingzong of the Ming Dynasty, abolished the burial, although there were no more concubines buried, in order to ensure the continuity of the etiquette, the subsequent emperors still kept this empty tomb.
If that's true
Then the tomb in Yongling must be empty, and it is indeed possible that the "Yongle Dadian" is stored.
However, not many people agree with this concept. After all, there is no concrete evidence to support it.
At the same time, if the "Yongle Dadian" exists in the left side hall, then it must have lost the significance of saving it, so it is called the Advent Sect.
Even fewer people agree with the second concept.
Because the layout of the underground palace is an absolute restricted area.
The restrictions on the upper and lower floors are better, but if you dare to open a small door on the same floor, Zhu Yuanzhang would be so angry that he would come over and beat you to death during construction.
Therefore, among all viewpoints, survivalists are the majority.
It seems now
Xu Yun seems to be a survivor too?
A few more minutes passed.
Zhang Han raised his head from the operating table and said to Xu Yun:
"Dr. Xu, the apse data collection has been completed. Do you want to move on to the next point?"
Xu Yun nodded decisively:
"Change places."
"Understood!"
After getting new instructions.
Zhang Han quickly took the communication equipment and determined the new point information:
"Coordinates 132,544, tilt angle 14.5°, horizontal movement from left to right 8.85 meters, expanded parallax 29.954, action!"
Huhuhu——
The drone in the sky quickly adjusted its position and circled to the right side of Baocheng to measure data.
After a few minutes.
"Coordinates 137,602, inclination angle 8.5°, horizontal movement from left to right 59.5 meters, expanded parallax 5.677, action!"
that's all.
Every seven minutes or so, the gravity gradiometer completes the measurement and changes its position.
More than an hour later.
The time came to 9:27 am.
Zhang Han raised her head from the console again, but this time she no longer reported the orientation problem, but asked:
"Dr. Xu, all the data below the underground palace have been collected, and the results are being analyzed and generated. Do you want the drone to land first and be on standby?"
at the same time.
Kakaka——
The printer on the console began to automatically generate inspection reports.
Seeing this, Xu Yun looked at each other and Academician Pan, pondered for a moment, and said:
"Okay, let the drone come down first."
"Received!"
More than a minute later.
The drone landed successfully.
At almost the same time as the plane landed, the printer also output the last report result.
introduced earlier.
The gravity gradiometer measures very fine data, and you cannot see the corresponding actual information if you take out a single section.
All its detection data can only be analyzed and summarized by computers after the mapping is completed. No one knows the specific results before that.
Therefore, even Zhang Han, who has been paying attention to the screen, does not know what the result of this report is.
After the report is released.
Zhang Han once again handed the thick stack of documents into Xu Yun's hands, and then stood aside with a curious look on his face.
She is not a big fan - to be precise, she is not a fan of any dynasty, but when it comes to "Yongle Dadian", this matter is not just a fan issue.
Wow——
Xu Yun first opened the first page of the document, which clearly displayed
The condition of the apse.
After all, it was the first tomb to be explored.
Xu Yun then checked the gradient database while looking at the report:
"There are four coffins stored in the tomb. The decoration is unknown and the material is unknown. The structure is high in front and low in back, wide in front and narrow in back."
"The four coffins are arranged in a layout with one at the top and three at the bottom. The lid of the upper coffin is 3.34 meters long, 1.48 meters wide and 0.22 meters thick at the head end, 1.35 meters wide and 0.19 meters thick at the foot end, and the bottom plate It is 3.33 meters long, 1.7 meters wide at the head end, 0.22 meters thick, 1.5 meters wide at the foot end, and 0.21 meters thick."
Jiang Chenggu on the side listened quietly, touched his chin and said:
"These four coffins should be those of Emperor Jiajing and the three queens. The layout, orientation and size are similar to what we know. Dr. Xu, are there any more?"
Xu Yun looked at the data a few more times and was about to turn the page when his eyes noticed a very strange measurement result:
"Hey this is"
Then he stopped and looked up the data carefully.
Then he checked the database on the computer, and a trace of astonishment suddenly flashed in his eyes:
"Director Jiang, according to the scan results, there is a gradient shadow of 0.003E level in the upper part of the apse, that is, inside Jiajing's coffin."
"I simply simulated this data, and the restored result should be a small closed jar of about ten centimeters, with something inside"
"Three round pill-shaped substances with a diameter of three centimeters and a strong mercury reaction"
