When it comes to the excavation of the underground palace, it is far from being as simple as Yu Fei imagined. In particular, Ye Jianjun's words when discussing the excavation plan stunned the well-informed experts.

The goods said with a big grin: "What's so difficult about this, I'll let the 'Erjian' pick a few skilled workers, bring the guys over, and open the underground palace in one afternoon!" ”

Looking at his smug expression, the experts were dumbfounded.

Luan Minggui was silent for a long time, and then said, "Where did this contractor come from?" Ye Jianjun's face turned red.

Yu Fei laughed secretly in his heart, who made this guy not know how to pretend to understand, and he still likes to behave.

After listening to Luan Minggui's explanation, Yu Fei realized that excavation is actually a very complicated job.

Excavation itself is a destructive process, and excavation is a very dangerous time, as fragile excavated artifacts are placed in a rapidly changing environment and risk complete destruction. The newly unearthed cultural relics are very fragile, and it is only after the first three years that the internal state of the unearthed cultural relics can be initially stabilized.

When excavating the Mawangdui Han Tomb in Changsha, a pot of lotus root soup was found, and when the container was just unveiled, you can still see a very complete lotus root floating in the soup, but it soon turned into a puddle of water. Because after more than 1,000 years, the internal physical and chemical structure of the lotus root has undergone major changes, and once it is returned to the normal temperature of the normal temperature, it cannot maintain its original appearance at all.

Therefore, before excavating, it is important to be well prepared. From excavation to extraction to transportation, it is necessary to take into account all aspects such as moisture prevention, mildew prevention, shock prevention, and theft prevention. Fortunately, the winter temperature in Kyoto is very low, which is still very helpful for the preservation of cultural relics. But that's it. Freezers are still to be prepared on site, and refrigerated trucks are used for transportation.

"Judging from the current situation, the outer edge of the underground palace is well preserved. But. After hundreds of years, the exact shape of its interior remains a mystery. I'm worried about whether there will be stagnant water in the underground palace, and there may be some fine mud flowing in, which will have a bad impact on the cultural relics inside, and I must fully plan for it. Luan Minggui said with a frown.

The excavation of the underground palace is to better protect the cultural relics, and improper operation may bring unimaginable damage to the cultural relics!

Actually, the situation in the underground palace. Yu Fei "looked" clearly, and the stagnant water or the inflow of fine sand that Luan Guiming was worried about did not appear.

But helplessly, he couldn't say it.

Otherwise, people ask him, how do you know? How did he answer? Guess? Or can I see it? I'm afraid not.

In the end, Luan Minggui came forward to find a German archaeological excavation team. This archaeological excavation team has a lot of experience in successfully excavating and preserving the pyramids of Egypt.

In this regard, Yu Fei's heart was a little uncomfortable. Unfortunately, China's technology is indeed inferior in this aspect. If it is hard, of course, there is no problem, but it is very likely to cause immeasurable damage to the cultural relics in the underground palace.

Luan Minggui could only persuade Yu Fei: "We are not cooperating with the German archaeological team this time. It's just a simple employment relationship. Strictly speaking, they're just our buddies. ”

Luan Minggui's self-deceptive speech, Yu Fei could only acquiesce.

Only Ye Jianjun kept shouting that he wanted to go to Erjian to find a few skilled workers. Of course, no one would bother with him.

The official excavation of the dungeon began on the third day. Of course, Ye Jianjun came forward to handle all the formalities.

Fearing that the German archaeological team would deliberately damage or negligently damage the original of the Yongle Canon, Yu Fei insisted on participating in the excavation.

After some bargaining, the price of 2 million labor fees was finally finalized.

In this regard, Yu Fei jumped up again.

"Two million?! Why don't you grab it? Yu Fei shouted: "Two million, enough for me to build two villas." This foreign devil is too dark. ”

It's not that Yu Fei can't come up with so much money. Originally, the Germans were asked to dig up, but he was already very unhappy in his heart. Now that he has to pay such a large sum of money, the fire in his heart is even greater.

"Besides, we people are also going to help from beginning to end, don't we even count a little salary?" Yu Fei shouted again.

"In fact, it's because you joined us that we only need two million. Otherwise, 1.8 million is fine. Daniel, the captain of the German archaeological team, said.

This time Yu Fei was dumbfounded. It turned out that he was a burden in the eyes of the Germans. Looking at this meaning, the extra 200,000 seems to be tuition. However, let Yu Fei not participate, he is not at ease, the skills of these foreign devils are passed, but who knows if they will do their best?

If you can guarantee the unearthing of the original copy of the "Yongle Canon" for two million yuan, then the price is worth it. And it's also a lot easier.

Qin Xiaojin also participated in the whole excavation, but in front of so many people, the two couldn't communicate too much.

The underground palace is the most common form of pit. Different from ordinary dungeons, this dungeon is nearly 10 meters below the surface, if it weren't for the detection showing the location of the dungeon, the foreign devils would almost have to give up. They have also excavated the underground palace before, but it is generally not more than five meters, and the excavation of ten meters has not yet reached the entrance, which is indeed very rare.

And the solidity of the Daxiong Treasure Hall is also greatly beyond everyone's expectations, the foundation is composed of the outermost layer of foundation groove, the stone rammed layer, the inner circle of the original mountain soil layer, of which the stone rammed layer is a layer of rammed earth and a layer of stone "sandwich" type, there are actually 36 layers!

The archaeological team "dug out" a little bit of the underground palace pit with a diameter of about 2.2 meters in the soil, and at 9.2 meters above the ground, the archaeologists finally found a bluestone slab, the stone slab is about 0.9 meters long and about 0.25 meters thick, and there is a layer of blue bricks tightly around it, which seems to be covering the cover plate at the entrance of the underground palace.

Seeing the bluestone slab, Ye Jianjun and the others were very excited, thinking that this was the door of the underground palace.

But Luan Minggui poured a basin of cold water on him again: "This shouldn't be the last door." Underneath the bluestone, there should be at least 50 cm of multi-layered rammed earth and stone layers. This bluestone has no actual architectural function, but is a kind of "hint": this place is not far from the door. ”

"Hey, that's the trailer before the movie is officially released, right?" Ye Jianjun said.

For Ye Jianjun's layman, Luan Minggui has long been used to it, so he ignored it.

In the next excavation, the foreign devils were obviously a lot more careful. And Yu Fei and the others were also ordered not to do it again, otherwise, they would be fully responsible for the damage caused to the cultural relics. In this regard, Yu Fei could only reluctantly stop. Although he can clearly see everything in the dungeon, it does not mean that he can safely take out the cultural relics in the dungeon, after all, he is just a layman.

The archaeological team first cleaned and lifted the bluestone slabs and brick-cladding, and continued to dig down to remove the rammed earth and stones until the underground palace cover was finally found.

After discovering the cover of the underground palace, the archaeological team did not immediately untie the cover, but first reinforced the underground palace. Because the underground palace is a pit structure, it is very easy to collapse, and the underground palace wall must be reinforced and protected. In the end, the archaeological team used caisson technology to strengthen the underground palace, that is, a cylindrical steel frame was placed on the wall of the underground palace to avoid the collapse of the underground palace.

Before opening the door, the archaeological team used remote sensing equipment to measure the general shape, volume and location of the dungeon, which made Yu Fei very impatient, because in his opinion, all this was superfluous. The dungeon has no secrets in his eyes! But the archaeological team was so careful, he couldn't say anything. After all, this reflects the responsibility of foreign devils.

On the third day of excavation, the archaeological team finally decided to open the gate of the underground palace. With a heavy sound, the dungeon was finally exposed in front of everyone's eyes. Facing the entrance of the underground palace of the black hole, Yu Fei took a flashlight and wanted to take care of it, but was stopped by the archaeological captain. Because the beam of the flashlight is likely to have a bad effect on the artifacts in the dungeon.

Then they measured the ambient gas, temperature and humidity, and liquid pH in the dungeon one by one, and then the main thing was to play.

If the excavation of the dungeon is compared to a dish, then it was just a dessert before the meal, and the main meal has not yet begun! For excavation, the ultimate thing is to develop a plan for the extraction of cultural relics. If you don't do this step well, then it will be useless before! The original copies of the "Yongle Canon" extracted this time are all ancient books that have been preserved for hundreds of years, and it is the most troublesome to extract. Will the German archaeological team be able to handle this difficult task? You must know that the loss of any one book may be an eternal regret. (To be continued......)
