After the charter was settled, the camp suddenly became busy, it turned out that once the state machine was operational, the efficiency was not ordinarily high, Zhuang Rui just briefly mentioned the underground situation to Professor Meng yesterday, and now a lot of relevant equipment has been prepared. Pen fun and pavilion www.biquge.info

Five sets of diving equipment representing the most advanced level in China were placed in front of Zhuang Rui and others, as well as various wireless equipment and lighting systems that can work continuously for more than 72 hours, all of which were to be brought down this time.

If it weren't for the preliminary survey, it is estimated that even the bulky diesel generator would have to be brought down.

There are also five sets of clothes specially used for dangerous operations, which, according to relevant professionals, can withstand the erosion of strong acids in a short period of time, and are used by Zhuang Rui and others to pass through the rock wall covered with "slugs".

In addition to Zhuang Rui, the people who followed him into the water this time are all young scientists with a certain status in the domestic archaeological or historical circles, and the main criterion for selecting the team members this time is that they must be physically strong.

This is also something that cannot be helped, the undercurrent at the bottom of the lake is turbulent, and Professor Meng, who is seventy or eighty years old, cannot be allowed to dive into the dark river like a young man, right? Of course, this young man is also relatively speaking, and the oldest one is also forty years old.

Ren Chunqiang is the second person to enter the underground dark river, and with his age advantage, he is also fortunate to be a member of the exploration team, and among the other three people, there is also a professional who debugs wireless equipment.

Through the underwater camera carried by Zhuang Rui and others, the people on the shore clearly saw the situation at the bottom of the lake, which made them amazed, if it wasn't for Zhuang Rui's "mistake", no one would have been able to find out that there would be such a shocking secret hidden at the bottom of the lake full of aquatic plants.

With professional diving equipment, it became easy to enter the waterway at the bottom of the lake, and after a few minutes, Zhuang Rui led the four people through the waterway smoothly and entered the dark river.

After hanging a few lights on the rock wall, the situation in the cave suddenly appeared clearly in the ground monitor, and the camera pointed at the pile of gold cakes underground.

Counting the dynasties and generations of China, the Yuan Dynasty is an era with the least historical imprints, whether it is the inheritance of items or culture, are very few, and now these items with a strong Yuan Dynasty color appear, suddenly make the scientific expedition personnel on the ground excited.

The old Mongolian linguist, who had lost half of his teeth, almost danced with excitement when he looked at the pieces of gold cakes that were close to the camera.

"Zhuang Rui, you go ahead and take a look at the place where there is strong acid......" Professor Meng's temporary headquarters on the ground issued an order to the exploration team below.

"Understand ......"

After Zhuang Rui nodded and agreed, he led the four of them to the depths of the river, this time several people were wearing one-piece clothes and boots, and the speed of travel was much faster than when Zhuang Rui first came in, and after more than ten minutes, he came to the top of the rock wall that was not satisfied with the dense "slugs".

"This is a phenomenon unique to karst landscapes......"

"Yes, these objects do have strong acid ...... in them"

After seeing the "slugs" at the top of the rock face, two geologists on the site gave an answer, which is a very common phenomenon in karst landscapes, caused by changes in soil and rock structure.

"Two, I wonder if people can get through here without any defenses?"

Professor Meng asked the two geologists that his concern was related to archaeology, and this geomorphological phenomenon has definitely existed for more than thousands of years, and it should have existed when the mausoleum was built.

This raises the question, if those people couldn't pass through here thousands of years ago, the mausoleum would never be in the depths of the dark river, and further, it is debatable whether there is a mausoleum inside.

In fact, after observing the underground situation from the camera, many experts present have begun to have reservations about whether there are Mongolian imperial tombs in the depths of the dark river.

Because some sections of the Dark River were so narrow, it was impossible to transport the materials used to build the mausoleum, and of course, no one in the venue could have imagined that this was just an escape route for the craftsmen at that time.

After observing through the camera for a while, a geological expert said: "As long as you pay attention to one point, people can pass through, the formation of these strong acids takes a long time, and a drop may take years or decades, otherwise this underground is not a river but a strong acid flow."

If the human body accidentally comes into contact with those strong acids, it only needs to be rinsed with water in time, as long as it is not the next strong acid rain, there will be no fatal danger......"

"Okay, Zhuang Rui, you pass through this area and continue to travel inside......" After receiving the reply from the geological expert, Professor Meng gave instructions.

With the protection of the protective clothing on their bodies, Zhuang Rui and his party quickly passed through this strong acid area, and continued to travel to the depths of the dark river, and found several traces of artificial excavation in some places where the terrain was relatively narrow.

All this made everyone on the ground very puzzled, saying that there is no mausoleum below, right? These traces also indicate that there were human activities here, but to say that to build an imperial tomb through this dark river is simply a fantasy.

When he traveled about seven or eight hundred meters, there was a fork in the underground dark river, but fortunately, there were obvious artificial marks at the fork, which also saved Zhuang Rui a lot of effort, otherwise he would directly bring everyone into the correct river, maybe some people would think.

Although the straight-line distance on the ground, from the entrance of the dark river to the secret passage of the mausoleum, is only a short three or four miles, but in the complex and winding terrain of the cave and dark river, this distance is infinitely magnified.

In addition, in the dark river, there are also many underground creatures that do not know whether they are poisonous or not, which slows down the travel speed of Zhuang Rui and others, and in some places it is necessary to move forward while surveying.

The group walked for nearly ten hours, resting three or four times in between, until the ground was already dark, and then they came to the exit of the secret passage of the tomb.

The exit of the secret passage is in an open place in the dark river where the water is turbulent.

Since this was an escape exit rather than an entrance, those craftsmen did not cover up this place, and the traces of manual excavation were very obvious, and Zhuang Rui and the others did not have much effort to find the hole covered with ringworm moss.

"Cave thieves?"

The experts who were already red-eyed on the ground, after seeing the cave entrance, couldn't help but make this sound in unison, they are all experts in archaeology, have rich field excavation experience, and are no strangers to such caves.

The appearance of this hole has also dispelled the doubts in the hearts of some experts.

If there is a robbery cave, there must be a large tomb, which is well known to the archaeological community, especially in such a mysterious place underground, the tomb on the other side of the robbery cave must not be simple.

However, the appearance of the robbery cave also indicates that the tomb has most likely been destroyed, which makes many experts feel pleasantly surprised.

"Zhuang Rui, your work today has been completed, and now you can return the same way......"

After some deliberation among the people in the temporary command headquarters on the ground, it was decided to withdraw the underground survey team, because if they rushed into the tomb through the robbery hole, they would face many unknown dangers, and the next step of the survey would be carried out after a lot of careful work.

Moreover, Zhuang Rui and others did not carry some necessary equipment to protect the burial goods, which would also cause damage to some precious cultural relics in the tomb.

…… By the time Zhuang Rui and his party returned to the ground, it was already more than twelve o'clock in the morning, but a group of scientific research experts in the big tent were not sleepy and were having a heated discussion.

After hastily replenishing some drinking water and food, Zhuang Rui and others, who were exhausted, were also called into the tent, and as the first batch of expedition members under the supervision of the relevant departments, they would all become part of the excavation.

"Now it can be basically determined that there is indeed a large tomb underground, and the tomb of the Mongolian emperor is preliminarily identified, but the identity of the owner of the tomb needs to be further investigated......

After some discussion and dialectic, Professor Meng announced the establishment of the Mongolian Imperial Tomb Excavation Headquarters, because today's date is July 28, this scientific expedition has also been named "7.28 Inner Mongolia Major Scientific Expedition Project".

Everyone present, including Battle and others, who first discovered the dark river at the bottom of the lake with Zhuang Rui, were also included in the research team, which also included the consideration of allowing Battle to coordinate with the locals.

In addition, Ouyang Zhenwu became the commander-in-chief of the excavation, but he was busy with things and would return to Běi Jing early tomorrow morning, so Professor Meng became the on-site commander of the operation.

As for the deputy commander-in-chief, there are six people, including a leader of the Inner Mongolia Autonomous Region, as well as several well-known experts in the field of archaeology in China.

As the discoverer of the tomb, Zhuang Rui also became a deputy commander-in-chief of the operation under the nomination of Professor Meng, which made Zhuang Rui a little unexpected.

However, Zhuang Rui has previously discovered the tomb of Liu Xiu, which has unearthed a large number of precious cultural relics and historical materials, and has the two achievements of the běi elite skull fossil and the shipwreck of the Song Dynasty, which is also well-known in the domestic scientific research community.

In addition, this tomb was discovered by him, and others did not have any objections, and the framework of the headquarters was structured.

Such a scientific expedition project of far-reaching significance must be announced to the world, so Minister Ouyang's task is to immediately hold a relevant press conference to announce the news to the world after returning to Běijing.

And this partial place, which was originally located in the depths of the prairie, will also become the focus of the world.
