on the ground.

   Hear what Xu Yun said.

  Jiang Chenggu, Academician Pan, Weng Tong, Huang Yuting, Tong Huaijun, Zhang Ziang

  These experts and scholars who had expressed their opinions, or were silent but listened very carefully, were suddenly stunned.

   After a while.

  Jiang Chenggu suddenly felt an inexplicable heat coming from the base of his ears.

   Immediately after.

   bang bang bang—

  He heard his own heart pacing—a signal of increased blood flow in his brain.

  Jiang Chenggu subconsciously glanced at the detection bracelet on his hand, and found that the real-time heartbeat displayed on the screen had reached the .

  129.

  However, Jiang Chenggu didn't care about this situation at all. He swallowed his saliva quickly, and asked Xu Yun seriously:

   "Dr. Xu, are you sure you can see clearly?"

   "Is there really another underground palace under the Nine Palaces? And there is no water?"

  Although Jiang Chenggu was extremely emotional at this time, he still maintained the most basic sobriety.

  Although his tone was hasty and serious, his tone was not high, and he didn't lose his composure enough to yell.

  The communication range of the sound is still kept within a few meters around.

  唰—

  At the same time, as Jiang Chenggu raised these questions, the eyes of the rest of the people also focused on Xu Yun, waiting for Xu Yun's confirmation.

  Facing everyone's eyes, Xu Yun nodded neatly:

   "That's right, Director Jiang, according to the detection results of the gravity gradiometer, there is indeed another underground palace under the Ninth Palace."

   "The confidence level of this detection result is very high. It is not the unsure speculation of "suspected" and "possible" in common concepts, but a conclusion that can be called a solid hammer."

   "As for the determination of water accumulation, Director Jiang, this is the most basic category in the field of gravity remote sensing surveying and mapping."

   "Not to mention the gravity gradiometer, ordinary microgravity remote sensing equipment is impossible to make mistakes."

  Xu Yun's tone was firm.

   This is somewhat contrary to his usual aggressive, ahem, conservative style.

   After all, what they are communicating now does not allow him to hide his clumsiness.

   Besides, the concept of judging the situation of water accumulation is the basic disk of gravity remote sensing surveying and mapping.

   Well known.

  Gravity changes on the surface are basically caused by material migration, and the most variable variable in the short time scale on the earth is water.

  So water remote sensing surveying and mapping can be called the root of all evil in the field of surveying and mapping, just like the broken chapters of the starting point, it is a must-learn knowledge for entering the industry.

   Therefore, as early as the 1970s, the international gravity detection technology for water was very mature.

Of course.

  The above sentence refers to the normal area.

  Some places in North America are close to the North Pole, so their mass change is measured by a model called GIA, which is rebound after ice, which is an abnormal situation.

  In 2003 and 2009, the country conducted two rounds of microgravity remote sensing detection on Yongling.

  The results of the two rounds of detection were not satisfactory, and it was impossible to detect which important cultural relics existed inside the Yongling Mausoleum. Only two situations were confirmed.

  First, the Yongling Mausoleum is the same as the original Ding Mausoleum. The interior is similar to the "A"-shaped structure, and the underground palace has a total of nine supporting halls.

  The second is that the water accumulation inside Yongling is extremely serious.

   At the level of technology at the time, it was still possible to detect the accumulation of water inside Yongling, let alone the detection ability of the gravity gradiometer today.

  After that, Academician Pan took the detection results from Xu Yun and looked at them for a while, then turned a few pages, and his eyes suddenly focused:

   "Huh? This is."

  Jiang Chenggu's heart tightened when he saw this:

   "Academician Pan, what's wrong?"

   "Oh, nothing, nothing, just thought of something else."

  Academician Pan came back to his senses. He quickly glanced at Xu Yun, handed the report back and said:

   "Director Jiang, in short, what Xiao Xu said is correct, there is indeed an underground palace under the Ninth Palace."

   "The area of ​​the lower underground palace is about 50 square meters, which is equivalent to 20% of the left and right side halls, and there is indeed no feedback from water accumulation."

  “.”

  Although it is a little difficult to understand Academician Pan's short-lived expression.

  But Jiang Chenggu quickly withdrew his attention and focused on what they were discussing now.

  Seeing that academician Pan and his apprentice are so sure of the existence of the lower underground palace.

  Jiang Chenggu's heartbeat not only did not drop to the normal value, but quickly increased a lot:

   "Then Dr. Xu, are there any objects inside this brand-new underground palace?"

  When I said this.

  Jiang Chenggu stared fixedly at Xu Yun, for fear of hearing a negative or 'undetectable' reply.

  However, Xu Yun looked very strong this time, and he quickly nodded again:

   "Yes, according to the report, there are a large number of closed boxes stored in the lower underground palace, occupying about 80% of the area of ​​the tomb."

   "The appearance of these boxes has obvious metal gradient differences, while inside the boxes. A large number of stacked shadows similar to books have been detected. The main gradient value judgment is"

   "Sap Organics."

  Boom—

  Xu Yun's words were like mushroom bombs dropped on a neon boy, and exploded in everyone's hearts.

  The scene suddenly became like Hiroshima after the explosion, and needles could be heard.

even

  It was more silent than when I heard that there was a lower dungeon.

   Except for Academician Pan who has seen the gradient detection report, everyone seems to have turned into a sculpture.

  咻~~~~

   Exactly at this time.

   There was a slightly stronger wind blowing in the distance.

  Everyone's hair fluttered in the wind, and the wig of Engineer Ma, who was in charge of network security, was blown aside.

  But everyone is still like a scarecrow standing in the wind in the wheat field, motionless in the wind.

  This news is really amazing.

   After a while.

  Weng Tong rolled his eyes a few times, and was the first to come back to his senses.

  I saw him take a big step forward suddenly, put his hands heavily on Xu Yun's shoulders, and even trembled in his tone:

   "Xiao Xu. How big are the boxes and books you mentioned, and how many are there? Tell me quickly!"

  Weng Tong's not-so-tall body exploded with astonishing strength at this time, so much so that Xu Yun's shoulder hurt a little from being scratched.

  But Xu Yun didn't care about this feeling, but quickly turned the report to the next page.

  Different from the content on the first page.

  The report on the first page contains relevant information about the water accumulation and the scale of the underground palace, which can be regarded as a summary at the beginning.

  So Xu Yun can report the relevant situation without much need for comparison.

   But the new page is different.

  This page contains a large amount of gradient data, so even Xu Yun has to rely on the nearby database for analysis.

   "0.0006T should be 1.2m"

   "△4.65 is about 52 cm"

   "Right character 5T-3, oh, found 30 centimeters."

   It took a while.

  Xu Yun just raised his head from the console.

  At this moment, even Xu Yun himself didn't notice that his hands holding the data report were trembling slightly.

   Then he glanced at Weng Tong who couldn't wait, took a deep breath, and said:

   "Professor Weng Bo Weng, according to our data comparison, the final internal situation of the underground palace is as follows."

   "There are a total of 18 boxes with metal gradient feedback in the underground palace, and the specifications are all 1.5x2x1, and the unit is meters."

   "Some of the boxes are stacked. That is, another box is placed on top of one box."

   "There are tree pulp organic matter 50 cm long, 30 cm wide, and 3 cm thick inside each box. It can basically be determined that they are books placed in a vertical style inside the box."

   The voice just fell.

  Weng Tong on the side picked up a pen and paper from the table and began to calculate by himself.

  Although Weng Tong is a solid liberal arts student, at this moment, he has exploded with unprecedented mathematical literacy:

   "1.5x2x1, the volume of a box is 3 cubic meters. Well, 3 cubic meters is right."

   "The volume of a book is 0.5x0.3x0.03 which is 0.0045 cubic meters, so a box can store 667 is wrong, this cannot be rounded, it should be able to store 666 books."

   "If the books were bound with rope or on shelves, then the number would be less. A box of 650 would have been fine."

   "650x18 is"

   Count here.

   Weng Tong's pen tip suddenly squeezed hard, piercing a hole in the manuscript paper of the calculation.

  But he didn't care at all, and quickly wrote down the answer to the calculation in another blank space:

  11700.

  Then Weng Tong slowly raised his head, looked at his old partner Tong Huaijun, and murmured:

   "Old boy, what are the specifications of the Yongle Grand Ceremony?"

  Tong Huaijun took a deep breath and said slowly:

   "The Yongle Encyclopedia was completed in the sixth year of Yongle, with a total of 22,877 volumes, 60 volumes in the catalog, and 11,095 volumes."

   "According to the statistics of "Shangshu Supplement" and the few existing copies of Yongle, the original version of "Yongle Dadian" is large in scale and single volume"

   "50.3 centimeters high, 30 centimeters wide, and about 2-3 centimeters thick."

have to say.

  Tong Huaijun, who also serves as the commentator of Jinling Museum, has a very magnetic and charming voice.

  Long and sweet like a jar of old wine, everyone was in a daze for a while.

   But soon.

   This artistic conception was broken by Huang Yuting:

   "So Professor Weng, Professor Tong, those boxes under the underground palace contain the "Yongle Dadian"?"

  Tong Huaijun nodded upon hearing this, took a deep breath, and was about to speak:

   "That's right, it's probably "Yong"

   As a result, before Tong Huaijun finished speaking, Weng Tong quickly interrupted him:

   "No, definitely not!"

  Tong Huaijun turned his head and stared at Weng Tong blankly:

   "?????"

  Tong Huaijun's expression at this time is quite similar to the expression pack created by teacher An Tianxu at the Tchaikovsky International Music Competition because the organizer put the wrong song.

  Xu Yun, Jiang Chenggu and others were also taken aback.

  What's the situation?

  According to the data released by Xu Yun, the books in the underground palace are almost certainly the "Yongle Dadian" - this was calculated by Weng Tong himself.

  As a result, why did he start to deny it now?

   Then, under the eyes of everyone, Weng Tong continued to say uncharacteristically:

   "The number of books doesn't explain anything. I personally think that the things in the box should be blank pages or other books buried with Jiajing. In short, it can never be "Yongle Dadian."

   "If the "Yongle Dadian" really exists in the underground palace of His Highness the Ninth Prince, I will go and eat the ax that is still in Rongcheng on the spot!"

  Everyone:

  “.”

  Xu Yun also opened his mouth, wanting to say that utilitarian milk is not advisable.

   But after seeing Weng Tong's tense facial muscles, he still gave up the idea.

  In the past two days, Xu Yun and Weng Tong also had contact several times.

  Combined with Weng Yujing's previous introduction, he also had a general impression of the old comrade Weng Yujing was talking about.

be honest.

  Weng Tong and Xu Yun have almost the same image of the previous generation.

  Stable personality, unsmiling, only rely on listening to books when reading novels, pay attention to efficiency and never talk nonsense

   But he is such a rigid uncle.

  In order to ensure that "Yongle Dadian" can be successfully presented in the world, it was even so "humble" that it took the initiative to insert a reverse flag.

  Perhaps for Weng Tong personally.

  The "Yongle Dadian" must have some reasons to be unearthed smoothly.

  Therefore, including Xu Yun, Lu Chaoyang and others, no one at the scene broke Weng Tong's flag for the first time.

   Then after a while.

   Lu Chaoyang, who had been silent all this time, suddenly raised his hand and asked Xu Yun:

   "By the way, Xiao Xu, I have a question that I haven't figured out. I don't know if it's convenient to ask now?"

  Xu Yun turned to look at him, and said cheerfully:

   "What's the problem? Professor Lu, just say it."

  Lu Chaoyang thought for a while, then pointed down with his index finger twice:

   "Xiao Xu, let me ask you first, how thick is the soil layer between the underground palace of the Nine Palaces and the underground palace on the lower level?"

  Xu Yun glanced at the report, and quickly reported a value:

   "The thickness of the soil layer from the top of the lower underground palace to the bottom of the Jiudian underground palace is about 6 meters."

   "Six meters. That's about two floors, right?"

  Lu Chaoyang gestured a height in the air, and asked again:

   "The thickness of this soil layer can only be said to be quite satisfactory for the depth of the underground palace, so why is there no water in the lower underground palace when the drainage system of the Jiudian underground palace is completely ineffective?"

   "Let's not talk about the rain and floods for this thickness. It took hundreds of years for the water in the upper layer to infiltrate, and it should have infiltrated."

   Heard this question from Lu Chaoyang.

  Jiang Chenggu, Huang Yuting and others also nodded slightly.

  Lu Chaoyang's words happened to be the doubts in their hearts.

   was introduced earlier.

  For buildings like imperial mausoleums, water accumulation in underground palaces is extremely common.

   It can be said that there are not many imperial mausoleums and underground palaces that do not accumulate water.

   But water accumulation can also be divided into seriousness levels, and the degree of water accumulation in different imperial tombs is different.

   For example, some are more than ten centimeters.

  Some are half a meter long.

  Some one or two meters and so on.

   Among them, Yongling Mausoleum belongs to the most serious kind - there are about 30 imperial tombs surveyed and mapped by remote sensing in China at present, and none of them has more water accumulation than Yongling Mausoleum.

   In other words.

  The drainage system of Yongling Mausoleum has been completely scrapped. Under such circumstances, how could there be no water in the lower underground palace six meters below the Ninth Hall?

   After Lu Chaoyang finished speaking.

   Zhang Ziang, the engineering boss, also coughed lightly, and gave his views on the data:

   "Xiao Xu, I actually wanted to ask you just now. It's really strange that you said that there is no water in the underground palace at the bottom."

   "Because according to the soil samples we collected before, the soil in Yongling is a saturated and weak soil layer, with a void ratio of about 1.3 and an undrained shear resistance of 22.45KPa."

   "This is the standard lagoon-facies soil formed in the late Quaternary period, which is almost the same as that in Dingling."

"I did a simple calculation based on the data of Dingling. Logically speaking, the area within 14 meters below the Ninth Palace should be a water seepage area. The area within 6 meters should be at least 1/3 or even 1/2 of the volume of the underground palace. .”

  Looking at the questioning crowd, Xu Yun subconsciously exchanged glances with Academician Pan.

   After a while.

  The faces of the two suddenly showed a tacit understanding of a smile.

   Then Academician Pan took a deep breath, looked around everyone, and said:

   "That's right, if you simply look at the soil conditions, there should indeed be a lot of water in the underground palace under the Ninth Palace."

   "But the question is. Xiao Xu said before that the outer wall of the underground palace. Is it an ordinary layer of soil?"

  Everyone was taken aback for a moment.

   Then Jiang Chenggu reacted first, and a guess appeared in his heart:

   "Academician Pan, what do you mean"

  Academician Pan did not answer his words, but continued:

   "Actually, apart from the stagnant water mentioned by Xiao Lu, there is another standard logic that is difficult to explain in the underground palace at the bottom, that is, it does not conform to the etiquette system."

   "The layout of imperial tombs in ancient China must abide by fixed regulations, such as site selection, such as orientation, and such as the layout of the underground palace."

"The layout of the nine tombs is the standard etiquette of the Ming Dynasty. Even if Jiajing reigned for forty-five years, it would be difficult for him to break this rule—so many people would rather think that the "Yongle Dadian" is stored in the Zuobei Hall, or I don’t believe that Jiajing will dig another lower underground palace.”

   Hear this statement.

   Rao was still puzzled by the problem of stagnant water, so the two archaeological experts Weng Tong and Tong Huaijun nodded.

   These words can be said to have gone to their hearts.

   Mentioned earlier.

  In the group that believes that the "Yongle Dadian" exists in Yongling, it can be divided into three factions.

  respectively are Adventists who believe that Yongling is in the left side hall.

  Think that Jiajing opened a secret room on the same floor of the underground palace to store the "Yongle Dadian" alone.

   and Jiajing dug a second floor under the underground palace to accommodate the survivors of the "Yongle Dadian".

  The reason why the surviving faction disagrees with the salvation faction is that opening the secret room on the same floor of the underground palace violates the rules of etiquette, and the ruling and opposition parties must strongly oppose it.

But in fact.

  The views of the Survivor School are also somewhat inconsistent with the rules of the Ming Dynasty's imperial mausoleum.

  Because theoretically, the area where the emperor's coffin is located leads to the 'pole of the earth'.

  You dig a secret room under the pole of the earth, no matter what, it's a bit intimidating, right?

   It’s just that the etiquette system of the Ming Dynasty did not explicitly prohibit this kind of behavior, so the survivors are a little easier to accept than the rescuers—but only a little bit.

  The reason why many people adhere to the Survival School is not because they really believe in it.

   It is because the possibility of the Salvationists is almost zero, and at the same time, the Adventist School believes that the left side hall must have been submerged by stagnant water long ago.

  So many people chose the Survivor faction out of the perspective of good expectations.

  But the current discovery verifies the view of the survivors. For professionals like Weng Tong and Tong Huaijun, it is obviously impossible for you to say that they have no doubts.

  It’s just that their minds were all put on the exploration of whether there is "Yongle Dadian" in the underground palace at the bottom level. Regarding the fact that the underground palace exists in the lower level, they temporarily put it aside with the idea that existence is reasonable.

  But now I hear what Academician Pan said.

   This is indeed a bit strange.

   Accumulation of water, etiquette system.

  These two logical problems appeared at the same time, which cannot be explained by coincidence.

   Afterwards, looking at the bewildered crowd, Academician Pan didn't hold back anymore:

   "Everyone, I saw the results of the report just now, so I have the audacity to say something more instructive from the perspective of God, that is."

   "Your thinking has actually fallen into a misunderstanding."

  Jiang Chenggu was taken aback for a moment:

   "Misunderstanding?"

   "Exactly."

  Xu Yun nodded, and took over from Academician Pan:

   "In everyone's perception, the so-called underground palace should refer to a space dug out of the ground, which is equivalent to the basement in our modern buildings, right?"

   "But have you ever thought of another possibility?"

   "That is, the basement located deep underground is not necessarily a basement that was pulled out, but it may also be a box that was 'buried' in?"

  “.”

   Hear this statement.

  Everyone had a question mark on their faces:

   "?"

   But soon.

   Weng Tong was the first to react, his eyes widened:

   "Wait, Xiao Xu, you mean that the lower underground palace is actually a huge box buried underneath?"

   "That is to say, the books are packaged in a box, and there is a shell on the outside of the box?"

"bingo!"

  Xu Yun gave a thumbs up to Wengtong, and a trace of emotion appeared on his face:

   "The biggest difference between the 'box' and the 'basement' is that the basement has a walkway to the ground, but the box buried in the ground does not."

   "According to the detection of the gravity gradient meter, there is no connecting channel between the underground palace on the ground floor, the underground palace of the Nine Palaces and the ground."

   "That is to say, Jiajing took out a huge earth pit first, stuffed the 'box' into the ground, and then built the Nine Temples Underground Palace on top."

   "In this way, there will be no so-called problem of destroying the layout. Jiajing's talent is indeed a bit crooked."

  Jiang Chenggu and everyone:

   "????"

  Mom?

   Is this tmd okay?

   But think about it

   Does it really make sense?

  The so-called destruction of etiquette and layout refers to the matter of 'architecture'.

  But if you just put a 'box' under your own coffin and don't build a passage

   Then this has nothing to do with architecture.

  It's like a homestead in reality.

   You can’t build a basement for feng shui reasons, but you can bury a bottle of wine under the homestead site, right?

  According to the comparison of the area of ​​nearly 1,000 square meters of the upper underground palace, the lower underground palace is equivalent to you buried a refrigerator in your own underground.

  The behavior is weird, but there is really nothing wrong with the rules.

  Given Jiajing's unique attributes and his enthusiasm for "Yongle Dadian", it seems that he can really do this kind of thing.

   Then soon.

  Weng Tong realized another thing:

  Since it is a box, there must be six closed faces.

  In addition to what Xu Yun said to block stagnant water, then there are not many optional materials for these ‘surfaces’—after all, they have been blocked for more than 400 years.

  According to the information Xu Yun mentioned before.

  The area of ​​the underground palace on the lower floor is about fifty square meters, and many of the boxes containing books are stacked.

  Then let’s calculate the height of the ‘box’ as 3 meters.

  Assuming it is a cuboid with a bottom of 7X7, then the total area of ​​materials required by the six sides is .

  7x7x2+7x3x4

  182 square meters.

  Think here.

  Weng Tong couldn't help asking Xu Yun:

   "Xiao Xu, what material is the outer wall of that box made of?"

   "Copper? Or pure gold?"

  Xu Yun glanced at him:

   "The outer layer is copper."

   "Is it really copper?"

   Weng Tong touched his chin thoughtfully, the answer did not surprise him.

  The total area of ​​the six sides of the underground palace on the ground floor is about 180 square meters, and the volume is 50x3, which is 150 cubic meters.

  With the strength of the Ming Dynasty when Jiajing was in power, it is not difficult to get this size of copper.

   Actually.

  In the long history of China, there are many giant pure copper buildings, such as the most famous four copper halls.

  The Four Great Bronze Halls have always been known as the Four Great Golden Halls because of their superb craftsmanship, high value and resplendent resplendent.

   Among them, the most famous one is the Golden Temple of Wudang Mountain, also known as the Golden Summit of Wudang Mountain, located at the top of Tianzhu Peak, the highest peak of Wudang Mountain.

  The Wudang Mountain Golden Palace was built in the 14th year of Yongle in the Ming Dynasty. That is, in 1416, it is the earliest of the Four Golden Palaces.

  The statue of Emperor Zhenwu, weighing about 400 tons, is cast in copper and gilded. It is still magnificent after more than 600 years.

   There is also the heaviest bronze hall in Mount Wutai.

   Located on Mount Wutai, one of the four famous Buddhist mountains, Daxiantong Temple is a traditional building structure with double eaves and a gable top, with a total weight of 500 tons. It is the heaviest existing copper temple in my country.

  Wutai Mountain Copper Hall was built in the Wanli period of the Ming Dynasty. That is, in 1608, a little later than the Jiajing era, it is seamless from the inside to the outside.

  Wutai Mountain Copper Hall is 4.7 meters wide, 4.5 meters deep and 8.3 meters high, with a total volume of about 175 cubic meters.

  The largest copper hall is the Mingfeng Mountain Copper Hall, which is 6.7 meters high, 6.2 meters wide and 6.2 meters deep, with a total volume of 257 cubic meters.

  So in terms of Jiajing's ability, there is no problem in the feasibility of forging such a copper temple to seal the "Yongle Dadian".

  At the same time, the copper hall is fully enclosed. Or the water-proof ability of the copper box needless to say. In the history of archaeology, there are many examples of cultural relics preserved in sealed copper boxes that have not been corroded.

  Think here.

  Weng Tong couldn't help exhaling slowly:

   "It's no loss that it's Jiajing, this skill is really big"

  However, he hasn't finished expressing his emotion.

  Xu Yun's voice sounded in my ears again:

   "Professor Weng, in addition to the outer copper layer, the interior of the lower underground palace is also wrapped with a layer of material to strengthen the waterproof effect."

   "Is there any inner layer?"

  Weng Tong blinked, but he soon felt relieved:

   "This is normal. We have also found similar situations in many ruins. The inside of the metal shell is often attached with other materials, such as gold plating."

   "Xiao Xu, what is the inner material of the underground palace's copper shell?"

  Xu Yun raised his head and glanced at him:

   "Golden nanmu."

Note:

   I saw that some students mentioned normal temperature superconductivity in the comment area, so here is a brief talk about my opinion.

  First of all, although this technology is at room temperature, it actually requires high pressure to complete, and the pressure is 10kbar—note that it is kbar, which is 10,000 atmospheres, not 10kPa.

   That is, normal temperature and pressure superconductivity is still far away, and this technical path has nothing to do with controllable nuclear fusion.

In addition, the publisher is Dias, who has caused many controversial things. Many people are saying that his papers were withdrawn, but in fact the biggest black history is metal hydrogen—yes, he was the one who made the metal hydrogen thing , is still a joke.

  Finally, a little trick. When you see a certain technological achievement being boasted by a bunch of financial bloggers, you must be prepared for the distorted news.
