On the third day after the long holiday, it was finally time to officially visit the Qianling Tomb. The Qianling Scenic Area Management Office closed the park for three days in the name of cleaning up garbage in accordance with the meaning of the Provincial Cultural Relics Bureau.

Early in the morning, everyone gathered at the entrance of the main tomb road of Qianling on the southeast slope of the north peak of Liangshan, and Professor Dong announced to everyone: "The nature of entering Qianling this time is exploration, not excavation, so there are several disciplines that everyone must abide by. First of all, not a single artifact inside is allowed to be taken for any reason. Second, no damage of any nature should be carried out on any item inside, including walls, stone doors, floors, etc., unless absolutely necessary. Third, in view of the long-term closure of the Qianling, it is likely that there is not enough oxygen inside, but in order to prevent the oxidation of the cultural relics inside, oxygen will not be instilled inside, so everyone has to carry oxygen supply equipment on their backs after entering. ”

After speaking, Professor Dong asked Li Su to distribute the oxygen cylinders and miner's lamp caps placed on the side to everyone.

Yu Fei and Luo Zi had already carried a caving bag, but now they had to carry this oxygen cylinder, which was a little inconvenient, so they had to carry the caving bag on their chests, and then carried the oxygen cylinder on their backs.

After everyone was dressed, Professor Dong asked the staff guarding the entrance of the tomb to open the heavy iron door and lead everyone in.

Everyone wore long-range miner's lamps on their heads, and under the illumination of more than a dozen strong lights, the not spacious tomb road looked very bright.

Professor Dong introduced to everyone: "The entrance to the main tomb of Qianling is composed of two parts: a trench and a stone cave. The trenches were nearly 20 meters deep, and all of them were filled with stone strips more than one meter long and one to two feet wide. The tomb road is in the shape of a slope, with a total length of more than 60 meters, wide in the south and narrow in the north, with an average width of about 4 meters. The stone strips are stacked and interlocked along the slope from south to north, a total of 39 layers, the plane is exposed 410 stone strips, and there are more than 8,000 pieces of common stones in 39 layers. These stone strips are fixed with a swallowtail-shaped thin waist iron bolt plate, and the holes between the upper and lower are pierced with iron rods, and the molten tin iron juice is poured into one, and the stone strips are melted as a whole, and the whole tomb road is very solid. ”

Yu Fei sighed when he heard this: "With so many stone strips used in just one tomb, I really don't know how magnificent this Qianling Tomb should be." ”

Professor Dong said with a smile: "This Qianling Tomb is the 'crown of the tombs of the Chinese emperors in all dynasties', known as the 'first mausoleum in the world', and the project is so vast that it may far exceed the Pyramid of Khufu in Egypt." ”

Luo Zi stuck out his tongue on the side: "How much manpower, financial resources, and material resources will be spent on such a big project." ”

"The Qianling Tomb was built in 684 A.D., and it took 23 years for the project to be basically completed, and hundreds of thousands of labors were used to build the Qianling Tomb, and the treasures buried in it almost occupied half of the treasury in the Tang Dynasty."

"Ahh Half of the treasury! In ancient times, the construction of an imperial mausoleum was really a waste of money for the people, and it is no wonder that the Tang Dynasty has declined since then, and it must have something to do with the construction of this Qianling Mausoleum. Yu Fei said in surprise.

Professor Dong nodded: "It is indeed a bit related, in order to build the Qianling, the imperial court spent a lot of financial resources, which gradually weakened the imperial court's control over various places, which eventually led to the demise of the Tang Dynasty and formed a situation of five dynasties and ten kingdoms. ”

As they spoke, they came to a stone brick wall.

"This is the King Kong Wall of Qianling, passing through from here, it is the interior of the Qianling Underground Palace?" Professor Dong said.

"What is this Vajra Wall?" Yu Fei asked curiously.

"Ahh You don't even know about the Vajra Wall! Professor Dong was a little surprised, this expert in Ye Lao's mouth, the young man who brought the secret map of the Qianling Underground Palace, didn't even know the basic common sense of the tomb. Wang Qi and Lei Kun also cast disdainful glances from the side.

Ye Lao was busy explaining on the side: "This King Kong Wall is a kind of reinforced wall. The Vajra Wall is made of Vajra clay. Vajra soil is a kind of mixed soil in ancient times, that is, glutinous rice juice and several other kinds of flower juice are added to the unique loess of Huangtiyuan, which is characterized by incomparably hardness and inaccessibility. ”

"Brother is right, but the outside of the King Kong Wall of this Qianling is reinforced with stones, and the middle layer is King Kong soil, we have used instruments to detect it before, and the wall is almost more than two meters thick."

Ding Laosan smiled when he heard this: "Hehe, such a thick King Kong wall, even if you want to blow it up with explosives, it's not easy!" Dong Lao, you better tell me where the secret door is. ”

"According to the records, the secret door should be in the lower left part of the west side of this King Kong wall, let's go over and have a look." After Professor Dong finished speaking, he led everyone to grope on the west side of the King Kong Wall.

Soon, Wang Qi found a trace of a door more than one person high on the wall, and he shouted loudly: "Found it!" The secret door is here. The crowd quickly gathered around.

Professor Dong said: "The mechanism to open the door should be on the wall on the left, let's look for it." ”

Sure enough, not far from the secret door, there were three stone bricks that could be moved. It seems that it is the mechanism that opens this secret door.

"The method of opening the door recorded in the information is 461." Professor Dong said, fiddling with the three stone bricks.

He pressed four times on the first brick, six times on the second brick, and once on the third. Then he waited patiently for the secret door to open automatically.

However, after waiting for most of the day, there was no movement at all.

"Huh? Strange! I should be right! Li Su, show me the information. ”

After receiving the information handed over by Li Su, Professor Dong checked it for a while: "It's indeed true, the information recorded in the information is clear, the method of opening the door at the beginning was 461, why can't it be opened now?" ”

"Could it be that the mechanism that opened this secret door is broken?" Li Su said on the side.

"Hehe, this Qianling organ has not been broken for more than 1,300 years, and it has only been broken for a few decades, so it shouldn't be. Why don't you let me try it. ”

"Okay, then ask Brother Ding to try it." Professor Dong stepped aside and let Ding Laosan walk to the front of the organ.

Ding Laosan walked to the side of the mechanism, and only then did he fiddle with a cigarette effort, and the secret door slowly opened.

Professor Dong couldn't help but exclaim: "Brother Ding is really an expert, and he really deserves his reputation!" It's just that how did Brother Ding know the password of this organ? ”

Ding Laosan smiled: "Actually, Dong Lao, you told me." ”

"You mean 'four-sixty-one'? But I've tried it just now, and I can't open it at all, why did Brother Ding open it as soon as he tried it. Professor Dong was even more puzzled.

"Dong Lao doesn't know, this lock is also known as the Dou Zhuan Xing Shift Lock, every time it is opened, the password will be automatically replaced, but all the replaced passwords will not be generated at random, and they must be set in advance. In the eyes of Taoists, the number 'seven' is highly respected, and this Qianling Tomb was built by Taoist masters, and the password must also be related to seven. I tried to subtract each digit from the previous set of passwords with seven, and got another set of passwords '316', and when I tried it, it was opened, purely by luck. Hey! ”

Professor Dong's words made Professor Dong admire: "Brother Ding is not only knowledgeable and courageous, but also so humble, which is really admirable. ”

At this time, the old ghost standing by the door saw that the stone door had been opened, and was about to go inside, but was pulled by Ding Laosan: "What are you in a hurry, this Lei Ye is a first-class master of the Black Evil Sect, and it is a small skill to deal with a few zombies." Let's ask Lei Ye to go first. After speaking, Ding Laosan raised his hand and waved his hand and made a gesture of invitation to Lei Kun.

As soon as Professor Dong heard that Lei Kun could actually deal with zombies, he immediately cast an admiring look at him. Lei Kun couldn't refuse, so he had to bow his hand to everyone: "Since the third master is so elevated by Lei, then Lei is walking in front." With that, he strode into the stone gate.

The rest of the people followed behind and walked in one after another, Ding Laosan had a mind before entering, and he asked the old ghost to find a large stone slab to hold the stone door against it, so as to prevent the stone door from closing automatically.

After entering the secret door, there is a long corridor made of stone strips, the corridor is about one meter wide, about two meters high, and about one or twenty meters long.

The hall is also all made of stone slabs, and the four walls are full of colorful murals, which are very exquisite, Professor Dong's attention is completely attracted by these beautiful murals, and Li Su is holding a single-lens reflex camera to shoot hard, and the two of them have not noticed that on one side of the hall, there are seven sarcophagi neatly placed, and behind the sarcophagus, is a gilded door nearly three meters high.
