MTL - Into Unscientific-Chapter 489 The hidden second floor of the underground palace (continue nine thousand words to explode the liver

  Chapter 489 The hidden second floor of the underground palace

  “.”

   On the clearing.

   Hearing Xu Yun's words.

  Jiang Chenggu and others were subconsciously taken aback.

  As a civil servant in the GWY office, Jiang Chenggu may have relatively limited knowledge in science, and the knowledge of many physics and biology is indeed far inferior to that of Xu Yun and Academician Pan.

   Like a Gravity Gradiometer report.

   In his opinion, the above words are as indistinguishable as a heavenly script from beginning to end.

  However, in terms of disciplines, especially history, Jiang Chenggu is enough to hang up and beat these science and engineering men on the scene.

   So less than two seconds.

  A possibility popped up in Jiang Chenggu's mind:

   "Dr. Xu, what do you mean"

   "In Emperor Jiajing's coffin, are there still a few 'elixir' that he usually takes?"

  Xu Yun nodded with a subtle expression:

   "If there are no accidents, it should be."

be honest.

  Xu Yun really didn't expect to find this thing in Jiajing's coffin.

   As expected of you, Daoist.

   Well known.

  As one of the most popular dynasties in Chinese history, the Ming Dynasty has lived in the country for 276 years and passed on a total of 16 emperors.

   I don't know if it's because of the blood of the old Zhu family.

  These 16 emperors may have different abilities, but basically they all have various eccentricities.

   For example, the commoner emperor Zhu Yuanzhang.

  The well-known murderous maniac in history cuts people like melons and vegetables, and is as decisive as Li Guding chops books.

   Another example is Ming Xuanzong Zhu Zhanji.

   Zhu Zhanji's career after he took office was quite brilliant. He solved the rebellion of his uncles, further consolidated the northern Xinjiang area, and created the "rule of benevolence and propaganda".

   But he has a very strange hobby:

   I love fighting crickets.

  Unable to find an opponent in the palace, he succumbed to the market, fighting crickets with the grassroots, and rarely lost.

   And after he won, he always taunted his opponents, and even got beaten because of it, but he still enjoys it.

   Another example is Ming Yingzong Zhu Qizhen, a social expert, who is also a top-notch wonder.

  Due to the early death of Emperor Xuanzong, this gentleman became emperor when he was 9 years old.

   As a result, his emperor was restless, and he had to listen to the eunuch's imperial conquest. In the end, Tumubao was defeated and captured, and became a prisoner.

  According to the normal situation, this one is almost cold, right?

   Unexpectedly, Zhu Qizhen mobilized his social skills, not only turning the guard into his fan, but even the leader's younger brother formed a deep friendship with him, and married a wife in Wala.

  Later, Yang Shan made a fuss and took Zhu Qizhen back to Daming in a daze.

  When they were sent back to the Ming Dynasty, the Oirats sent them off once and then again, and they were very reluctant.

  Later, the civil war **** of war launched another coup, and became the emperor again.

   There is also Ming Guangzong Zhu Changluo.

  This gentleman is a product created by his father inadvertently, and he was not favored by his father and stepmother since he was a child.

   Fortunately, the ministers supported him, and after 39 years of hard work, he finally became the emperor.

  After taking office, Zhu Changluo was busy with political affairs every day, and his stepmother arranged a large number of beauties, and his body was quickly emptied.

   Seeing this, the stepmother ordered someone to put laxatives on her. She pooped thirty or forty times in one night. The sound of the imperial toilet changed from plopping to clattering, and finally it was ticking.

   It's not over yet.

   Then another wise man offered red pills, saying that it can be a great tonic, but this thing is actually the product of lead + mercury.

  This gentleman ate two pills, and the person who finished the matter disappeared immediately—it took a month from the upper position to the upper card position.

   There are many similar examples, such as the carpenter emperor.

   On the contrary, the subjugated Emperor Chongzhen was relatively normal. When he was leaving, there was Wang Chengen who died with him.

   Among these wonderful emperors of Ming Dynasty, there is another one that I have to mention.

   That is Jiajing.

   This wonderful woman explained one thing with the events of her life:

  What is [all talent points are crooked].

  Emperor Jiajing came to the throne at the age of 15, and his cousin was Ming Wuzong Zhu Houzhao.

  So he originally took the script of the prince who is extravagant and lustful, and eats and waits to die.

   It turned out that Zhu Houzhao had no children after his death, and no one could inherit the throne.

  So the cabinet Yang Tinghe and others who were ordered to draft a will could only complain about having no children, while choosing Ming Wuzong's cousin Zhu Houcong as the heir from the perspective of patriarchal clan and blood relationship.

be honest.

   When Jiajing first came to power, he really showed a strong talent and ability.

  He first issued an edict to abolish the bad government of Wu Zongshi, and then killed the courtiers Qian Ning, Jiang Bin and others, making the government a new one.

   Then, a dispute over rituals was triggered.

  The final result was that Jiajing revered his father as Ruizong, and put the **** into the Taimiao, completely mastering the authority of the emperor.

   Indeed.

  Great ceremonies prompted a group of upright ministers to retire, and some sycophants took the opportunity to take over, making the court's waters muddy again.

  But purely from the perspective of Jiajing or the emperor, this matter can be said to be profitable everywhere—I have officially changed from a puppet to a real emperor.

  If Jiajing can be diligent in governing the government, according to his previous means and judgment, those courtiers will probably not be able to make any big waves.

  For example, Hai Rui once commented on the early Jiajing in the Public Security Bureau:

   "Your Majesty is talented, wise, and knowledgeable. He can serve as Yao, Shun, Yu, Tang, Wen, and Wu... In the early years of his ascension, he eradicated the accumulated evils and made a new start with the world."

   But unfortunately.

  Jiajing suddenly went astray since then.

  He first became an avid cat slave.

  Looking at all the emperors in the history of China—including those outsiders in the Yuan and Qing dynasties, none of the emperors had a love for cats comparable to Jiajing.

  Jiajing raised more than 2,000 cats in the palace, and the palace also set up a special cat room, where eunuchs and maids carefully took care of the famous imperial cats in the cat room.

  1560.

  Jiajing's beloved cat "Shuangmei" passed away.

  In spite of the objections of his ministers, he buried Shuangmei in a golden coffin and was buried on the north **** of Longevity Hill with a very high standard.

  Establish a tombstone and name it Qiulong Tomb.

  In addition to playing cats, Jiajing also has a more well-known wonderful hobby:

   That is cultivating immortals.

   Jiajing was almost obsessed with cultivating immortals. He did not go to court for 24 years, and the strike time was second only to his grandson Wanli.

   As for Xiuxian, students who have read novels should know it.

  In addition to practicing exercises, the most common routine is naturally eating 'elixir'.

  So ever since.

  Jiajing practiced alchemy almost every day in the second half of his life, and the materials used in alchemy were extremely strange:

   Fingernails,

  The saltpetre in Laoba Restaurant,

   Bird droppings.

   Even the blood of the aunt of the court lady is used to make alchemy—this sentence is not an exaggerated description.

  During Jiajing's reign, there was a big change called "Renyin Palace Change" - this is a palace change recorded in history books and encyclopedias.

  The reason for the palace change was that the palace ladies wanted to strangle Jiajing to death because they couldn't bear this kind of torture.

  If it weren’t for the fact that the two dead knots couldn’t be tightened together, Jiajing would have been able to really ascend.

   Among these elixirs, there are two essential materials:

  Lead and mercury.

  So after Xu Yun said that there was mercury and pill reaction in Jiajing's coffin, Jiang Chenggu immediately thought of it

  The ‘elixir’ that Jiajing took!

   More critically.

  Although the Yongling Underground Palace is indeed filled with a lot of stagnant water.

  But in the case of a high degree of water filling, the things inside the coffin may remain intact.

  Because for vectors of plant origin.

  They are most afraid of being in an environment rich in moisture and air—because they will soon be spoiled under the action of microorganisms and oxygen.

   And if it is in a very dry environment or completely submerged in water, it can be stored for a long time due to the lack of humidity and air (water acts as an air barrier).

   As long as one of these two conditions is met, it should be stable for a long time.

  Organic matter can be preserved for a long time.

  For example, the buildings in Venice have been around for hundreds of years, and the wooden piles buried under the water are still intact.

   There is also the wooden pile of His Royal Highness Jinci Temple, which has been more than 900 years old and is still working.

   Archaeology and the wood industry have another catchphrase on this:

   Dry for a thousand years, wet for ten thousand years, half a year for neither dry nor wet.

   Not to mention the outside of the 'elixir', there is a jar and Jiajing's coffin for the second protection.

  So from a theoretical analysis, the degree of preservation of that 'elixir' should be .

   High!

   Indeed.

  This 'elixir' is absolutely impossible to be a real elixir, and it is harmful to the human body without any benefit.

  But it has extremely high research value for analyzing the "culture" of ancient emperors' Taoism:

   Everyone knows that many emperors in ancient times liked to cultivate immortals, and liked to take lead and mercury, but what kind of medicine did they take?

  This question has never been answered before.

  Even the National Museum has never had a specimen of 'elixir' before.

   So no question.

   This is a discovery with high research value and topicality, and making it public will inevitably lead to high topic discussions.

  Think here.

  Jiang Chenggu couldn't help but raised his eyelids, and asked Xu Yun again:

   "Dr. Xu, can the gravity gradiometer detect the completeness of the 'elixir'?"

  Xu Yun waved the report twice, shook his head lightly, and explained to Jiang Chenggu:

   "It's difficult to be honest. After all, the gravity gradiometer is not a perspective mirror. Its working principle is to complete the measurement based on the gradient difference."

"For example, for a three-centimeter elixir, the gradiometer will detect the gradient difference in the interval according to a certain accuracy, such as 0.01 mm, and then collect the gradient difference, which will be analyzed and interpreted by the computer-this is why we cannot grasp it in real time during the measurement process. specific information."

   "So now we can only judge the size of the 'elixir' and the mercury content. As for whether it is complete or not. I am afraid that we will only know after opening the tomb."

  Jiang Chenggu touched his chin thoughtfully:

"I see."

   I think so too.

  If the gravity gradiometer can completely analyze the preservation degree of the elixir

   Then what is it called a gradiometer? It can be called a gravity perspective machine.

   Then Jiang Chenggu thought for a moment, looked up at the sky, and continued to say to Xu Yun:

   "Dr. Xu, let's stop here about the elixir first. Let's continue the previous discussion—is there anything else found in the tomb besides the elixir?"

   At this time, the drone carrying the gravity gradiometer has landed and returned to its original position, and the scene looks the same as ordinary remote sensing mapping.

  So even if the pictures on the ground are captured by satellites, there is no major problem, and it is even less likely to leak secrets.

  So Jiang Chenggu was not in a hurry to get Xu Yun to submit the report.

   Instead, I learned about the specific situation on the spot to see if there were any other discoveries.

   "Except for the elixir"

  Xu Yun turned a page of the report, looked at the results above and said:

   "In addition to the elixir, the equipment also swept out a gradient difference shadow of the order of 0.068E inside the coffin that is highly suspected of being Jiajing Emperor's coffin."

   "This shadow is about the size of two palms, and the gradient is evenly distributed, with a very obvious reaction of pure gold—gold is one of the substances with the highest feedback in the gravity gradiometer mapping, especially in the environment of the underground palace."

   "In addition, in the other three coffins, we also found three hat-shaped objects with gradient feedback of pure gold and gemstones."

   "So judging from the supercomputing 'SSOM' that assists in summarizing the data, they should be Jiajing's funeral emperor's crown and the queen's phoenix crown."

   Heard the words Golden Wing Emperor Crown and Phoenix Crown.

  Jiang Chenggu's complexion remained unchanged.

  But in my heart, I was faintly relieved.

  Although the higher-ups have a very firm attitude towards this Yongling excavation, the approval of various procedures has not been delayed at all, and the support that should be given is also very strong.

  But after the news was made public, the competent authorities did bear a lot of pressure.

   First, it is a lesson from the Dingling tragedy that year.

  Secondly, I am worried that the preservation of cultural relics inside Yongling Mausoleum is not optimistic—after all, there was not much water in Dingling Mausoleum back then.

   Now I know that there are 'elixir' and four imperial crowns and phoenix crowns in the apse alone.

  So no matter what the final result is, at least there will be no embarrassment of finding important cultural relics after Yongling is dug up.

   This is obviously good news.

  At the same time, the apse is where the coffins of Emperor Jiajing and the three empresses are located, and there are not many utensils inside except the coffins.

   So a few minutes later.

  Xu Yun finished introducing the situation of the apse.

   "The next detection situation is Oh, You Peidian."

   Then Xu Yun moved his gaze down and introduced the second detected tomb:

   "The area of ​​the right side hall is about 240 square meters, about 20% larger than the right side hall of Dingling, and there are many items stored inside."

   "About 40% of these items have obvious metal gradient differences, and the rest are some bulky items, such as swords, clay figurines, etc."

   "At the same time, the positions of these items are extremely irregular, with horizontal and vertical orientations. It seems that the original order of placement was disrupted by stagnant water."

   "What? There is something in the right side hall?"

   Hear this sentence.

   Tong Huaijun, who had just rushed to Xu Yun's side, was taken aback for a moment, and hurriedly asked:

   "Then what about Zuo Peidian?"

  Xu Yun turned another page of the report, his eyes stayed on the paper for about ten seconds, and he quickly gave the answer:

   "Professor Tong, according to the test results, although there are not as many objects in the left side hall as in the right side hall, the density is still considerable."

   "From the point of view of the gradient difference, it should be something like lamps and clay figurines."

   "In short, whether it is the left side hall or the right side hall, it is impossible to have a large number of books inside—even if it is sealed in a box."

  Tong Huaijun subconsciously opened his mouth.

   But in the end still did not speak.

  As a professional archaeological researcher, how could he not understand the value of Xu Yun's words?

   has been introduced before.

  In the Dingling Underground Palace of Emperor Wanli, the left and right supporting halls are empty.

  Some people believe that the left and right side halls of the underground palace followed the old system and were used as tombs for buried concubines in the early Ming Dynasty, which is equivalent to the setting of the six palaces in the inner court of the Forbidden City.

  So after the burial of concubines was abolished.

  The system of setting up the left and right side halls in the underground palace of the imperial mausoleum still continues, but it is only for symbolic meaning, and it does not actually store things.

  Another view is that the auxiliary hall is originally the place where the burial objects are placed. The reason why the left and right auxiliary halls of the Dingling Mausoleum are empty is mainly because Wanli was buried in a hurry:

   Wanli’s business is not finished, and Taichang is gone—Taichang is the Ming Guangzong Zhu Changluo who died of diarrhea and eating red pills after a month of ascending the throne.

  The two emperors were going to be buried at the same time, so the funeral objects must not be enough.

  Therefore, there must not be as many burial objects in Wanli as planned in Dingling Mausoleum. Rather than placing them scattered in the left and right side halls, it is better to concentrate them in the middle hall and leave the left and right side halls empty.

   Now it seems

  The reason for the vacancy of the left and right side halls of Dingling Mausoleum is indeed the latter, so there are other funerary objects in Yongling Mausoleum.

   Indeed.

  Xu Yun's detection results confirmed that there are no books in the Zuobei Hall of Yongling Mausoleum, thus negating the possibility of the existence of "Yongle Dadian" in the Zuobei Hall.

But on the other hand.

  He managed to confirm some speculations about the imperial tomb without opening the tomb.

To know.

  Due to the fact that only the Dingling Mausoleum has been opened so far, many details of the emperor's tombs in the Ming and Qing Dynasties can only be analyzed, without any empirical evidence to refer to.

   In a sense.

  The current archaeological world is actually similar to domestic military fans:

  Army fans can only comfort themselves with a mop as Bartley, and the archaeological community can also only flip through books to guess a lot of ancient information.

   And now we have a gravity gradiometer

   It’s hard to say about the funerary objects, but at least the structure of the mausoleum can be analyzed, right?

  If you can fly more mausoleums in the future

   Maybe the archaeological community will be able to classify a set of authoritative conclusions about the ritual system of the imperial mausoleum without destroying the mausoleum!

  This is really a big topic, and it may even have an impact on the entire East Asian civilization circle-after all, Tangling has not been opened yet.

   And just as Tong Huaijun's mood was flying high.

  Xu Yun coughed lightly again, and continued to start a new round of reports:

   "In addition, according to the inspection, there are also a number of items stored in the small halls behind the left and right side halls, and the specific types are still unclear."

   "However, the area of ​​these two small halls is only a few square meters, so it is unlikely that there are large cultural relics."

   As he spoke, Xu Yun turned to the next page, introducing with the same terminology:

   "Then there is the aisle in the middle and the three tomb chambers in the vertical direction. From the structure. Er?"

   As a result, I kept talking.

  Xu Yun let out another light hey, and stopped talking.

  See this scenario.

  Jiang Chenggu on the side couldn't help being shocked, and asked quickly:

   "Dr. Xu, did the gravity gradiometer detect any new objects?"

  When Jiang Chenggu said this, there was a hint of excitement and curiosity in his tone.

   As the mausoleum of the supreme ruler of the ancient Chinese dynasty, the imperial mausoleum must have a lot of cultural relics inside. This is a concept that has been imprinted in everyone's cognition.

   So in theory.

  Simple and expensive things—such as jadeware, crowns and other utensils—would not surprise Xu Yun so much.

   After all, I have already been mentally prepared.

  Only something beyond precognition can make Xu Yun ask such a question.

   For example, the previous 'elixir'.

  And this time, what did Xu Yun discover?

   Is it a cat's coffin?

  Ultraman's transformation stick?

   Or a large bronze vessel?

   Or... the legendary "Yongle Dadian"?

   Just as Jiang Chenggu was frantically brainstorming, Xu Yun's light words suddenly came to his ears:

   "Uh, Director Jiang, it's a few fish."

  “.”

  Jiang Chenggu was startled when he heard this.

   After regaining consciousness.

  His neck subconsciously leaned forward a few centimeters in a funny way, his originally calm expression was full of astonishment:

   "Dr. Xu, what are you talking about?"

   Seeing this, Xu Yun raised the report in his hand and explained:

   "Director Jiang, according to the test results of the gravity gradiometer, there are at least five fish in the aisles of the underground palace."

   "The longest of these five fish is about 18 centimeters, the shortest is 4 to 5 centimeters, and the average length is about 10 centimeters."

   "In addition, I want to take back what I said before. Compared with pure gold, fish in the water are the things with the highest feedback accuracy"

  Jiang Chenggu was silent for a few seconds, and licked the dry corners of his mouth, still in disbelief:

   "But. But how can there be fish in the underground palace?"

   "It's impossible, no one can put fish in the emperor's tomb, right? That's the emperor's tomb."

   "Besides, what kind of fish can reproduce in the closed conditions of the underground palace from hundreds of years ago to the present."

   "No, it's still possible."

  Facing Jiang Chenggu's barrage of questions, Weng Tong on the side suddenly spoke:

   "Obviously there will be no fish in the imperial mausoleum at the beginning—even if there were, they would not be able to survive for a long time, because there was no water accumulation environment in the underground palace at the beginning."

   "But Director Jiang, have you ever thought that if the conditions are right, foreign fish may survive in the underground palace?"

  Jiang Chenggu was taken aback for a moment:

   "Exotic fish?"

   Weng Tong nodded, gestured to the treasure city in front of him with both hands and said:

   "For any imperial tomb, apart from the site selection, which is the geomantic treasure, there are only two key links."

   "One is the secrecy of the mausoleum passage, and the other is the design of the drainage system."

   "There are also two types of drainage systems, one is underground water seepage, and the other is external rainwater."

   Hear this statement.

  Rao, who is a science student like Xu Yun and Academician Pan who doesn't know much about archeology, also nodded at the same time.

  The underground palaces of imperial mausoleums are generally located very deep underground, which is a common problem of ancient emperors.

  For example, the underground palace of Qin Shihuang.

   Students who were Qin Shihuang in their previous life should know it.

  The Mausoleum of Qin Shihuang is located at a depth of 35 meters underground, and its vertical height is equivalent to that of an 11-story building.

   This height has far exceeded the depth of many wells. Although the area where the mausoleum is located may not necessarily have water veins, over time, some underground water will always seep in along the sand and gravel.

  The same is true of the Ming Tombs.

  The average underground palace depth of the Ming Tombs is 25.6 meters, so water seepage is a link that must be considered.

  As for rainwater, it is better to understand. When it rains, the rainwater accumulated on the ground flows into it.

   Then Weng Tong paused and continued:

   "Facing the two possible water accumulation situations, most imperial tombs have designed very effective drainage facilities."

   “These sewers are very efficient at first, but over time, they gradually become functional problems, or even... completely fail.”

   "For example, Emperor Qianlong's Yuling Mausoleum, there was a gap of more than 40 cm in the drainage facilities of this mausoleum, which was only repaired by the Cultural Relics Bureau in 1994."

   "Therefore, if there is a gap in the drainage facilities of Yongling Mausoleum and some floods occur at the same time, then it is indeed possible for river fish to break into the interior of the mausoleum."

   "Combined with underground water seepage and periodic rainwater inflow, the accumulated water inside the Yongling Mausoleum is not considered to be 'dead water'. If plants such as moss regenerate on those stone statues, then there will be food sources for fish."

  Looking at the eloquent Weng Tong.

  The initial surprise on Jiang Chenggu's face gradually calmed down, replaced by a look of thought.

  At the same time, he quickly recalled the map near the Ming Tombs in his mind.

  The Ming Tombs are located on the outskirts of Changping District, next to the Dongsha River, a tributary of the Wenyu River, and next to the Ming Tombs Reservoir.

  In this area in history, flood disasters often broke out.

   Actually.

  It was precisely because the floods affected the cottages and farmland on both sides of the strait that the country established the Ming Tombs Reservoir here.

   So in theory.

  When a certain flood broke out, several fish flowed into the underground palace through the drainage gap of Yongling Mausoleum.

   Also justified?

  Think here.

  Jiang Chenggu's expression couldn't help being a little subtle.

  He suddenly remembered that when he was sorting out the equipment, he found a fishing rod in the trunk of the car. At that time, the owner of the fishing rod said that he would throw a few rods in the pit

  Is this the fisherman?

Of course.

   This news was unexpected. After experiencing the early surprise, everyone quickly accepted this fact.

   Anyway, just a few small fish.

   So a few minutes later.

  Everyone turned their attention to the test report again.

   "These fish are located in the aisle of the mausoleum, and some traces of lamps and utensils were also clearly detected in the aisle."

  Xu Yun turned the page again, and after several introductions, he became more and more familiar with the layout of the report:

   "The area perpendicular to the aisle is three tombs, the central one is the nave, followed by the front hall, and finally the tunnel ticket."

   "In terms of area, the three decrease in order. The area of ​​the nave is also about 240 square meters, the front hall is about 150 square meters, and the tunnel coupon is about 30 square meters."

  Tunnel coupons.

   Although the name seems a bit of a mouthful, it is actually a very important node in the underground palace.

  It is the leading part of the underground palace, that is, the excavated sand will be transported out from here.

   In other words.

  The stone wall of the tunnel coupon is the outside of the gate of the underground palace, which is equivalent to the entrance in nature.

  This part was called "Ticou" before the Ming Dynasty, and it was changed to the tunnel ticket after the Ming Dynasty.

   It was further expanded in the Qing Dynasty, and structures such as tunnel vouchers, tomb passage vouchers, passage vouchers, and Mingtang vouchers appeared.

   Then Xu Yun picked up a bottle of C'estbon from the side, moistened his throat, and said:

   "According to the detection results, the tunnel coupon is filled with a large amount of sand and stones, completely blocking the entrance."

   "There are a large number of funerary objects sealed in the nave and the front hall. It seems that they should be artifacts such as jewelry, which were also submerged in stagnant water."

  After listening to Xu Yun's introduction.

  Jiang Chenggu nodded again.

  Xu Yun did not explicitly mention the information about the burial objects this time, which means that in terms of shape, there should be nothing particularly weird in these burial objects.

   followed by the next second.

  Jiang Chenggu suddenly discovered a situation:

  At this time, Xu Yun has already reported the situation of nine large and small tombs, but the thickness of the report in his hand is still left.

   Full half.

   Indeed.

  The current underground palace still has some information that has not been fully reported.

  For example, the length and width of the external tunnel, whether a certain area collapsed, and so on.

  But even if the entire tunnel collapsed and blocked up, theoretically, half of the thickness would not be left—after all, this was the work of Zhang Ziang and the others.

  Think here.

  A flash of lightning flashed across Jiang Chenggu's mind, and he asked Xu Yun in a hurry:

   "Dr. Xu, Could it be."

  Xu Yun glanced at him, understood his thoughts, nodded quickly and said:

   "That's right, Director Jiang, we found another tomb under the floor where the nine tombs are located."

"one."

   "A burial chamber without water."
