The First Emperor said with a smile: "Empress Zetian is right, this mausoleum gathered the best craftsmen and designers in the world at that time. The number of people in the whole team is about 1,000. ”

Ou Zhou sighed: "With such a grand project, there is no second one in the world." According to the scientific community today, physicists, chemists, architects, astronomers, and geographers worked together to design and build such a huge project. ”

Jiang Yang continued: "It took 300,000 people to build it for 39 years, that is, the construction of the Pyramid of Khufu, the landmark of the earth, only 30 years to build, and the number of people used every year does not exceed 100,000. ”

The First Emperor smiled: "I don't know what the Pyramid of Khufu is, but if my mausoleum is built on the ground, I am afraid that there will be no name for the Pyramid of Khufu, right?" ”

Ou Zhou nodded and said with a smile: "Yes, whether it is the extent of the project or the scientific and technological content of the mausoleum, this underground palace of His Majesty the First Emperor is definitely the first in the world." ”

Empress Zetian remembered an insoluble mystery at this moment and asked, "Your Majesty the First Emperor, you said that this space is sealed, but when the tomb door is opened, aren't you afraid of the leakage of mercury volatile gases?" ”

The First Emperor smiled: "This question was thought of at the beginning of the design. The volatile gas of mercury is much heavier than air and will not be emitted outward. It can only exist in this confined space, penetrating into the ground or into the four walls. ”

Empress Zetian gave a thumbs up and praised: "The First Emperor is worthy of being a person in the world, and he even understands such scientific truths, no wonder he gave you Yin Fruit, you don't want it!" ”

The First Emperor laughed and said, "If the Yin Fruit is stored in such a space, it will turn into a Silver Fruit. That's the equivalent of making me eat the silver. ”

Her Majesty sighed: "The feeling of the pavilion floating in the air is wonderful. His Majesty the First Emperor is the first person in the Yang world, and when he reaches the underworld, he can also be called the first soul! ”

The First Emperor laughed: "We are already friends, if Her Majesty likes it, you can come and play often in the future!" ”

The Empress rejoiced: "Well, we are not far away anyway, we were neighbors earlier, and now we are friends." ”

Ou Zhou and Jiang Yang looked around for a long time, and suddenly asked: "Your Majesty the First Emperor, it is rumored that Concubine Li was buried alive back then, where is the body now?" ”

The First Emperor sighed silently: "After Concubine Li was martyred, the residual oxygen left when the tomb was closed quickly ran out, and she accidentally fell into the mercury lake, but her body was completely preserved. I don't know exactly where it is, though. ”

The Empress nodded and asked, "Where is her ghost?" ”

The First Emperor was sad: "Concubine Li hates me to the bone, and the ghost is attached to the body, and she never wants to see me." ”

Ou Zhou and Jiang Yang couldn't help but be stunned for a moment, and after a while, they asked, "Your Majesty the First Emperor, where is your dormitory?" ”

The first emperor looked sad and said: "After the end of Mount Tai's meditation on the same day, on the way back, I mistakenly took golden erysipelas and died. It was a hot autumn season, so much so that the body was not protected. Her Majesty's body is so vivid and beautiful. I don't want to look at my corpse. ”

"What, Your Majesty the First Emperor, it is said that your funeral goods are huge in number, and there are countless treasures, where are they placed?" Ou Zhou said curiously.

The First Emperor waved his hand and smiled: "In the entire mausoleum, there are everywhere. It's just covered by mercury volatile gases, so as far as to see, it's silver. ”

Ou Zhou nodded, and asked again: "Your Majesty, the basha wood you just talked about, as far as I know, this kind of wood is produced in the tropical rainforests of South America, and it does not grow in our country. How did Your Majesty get this fine wood? ”

The First Emperor smiled, "This is a very good question, maybe I said that you may think it is a fantasy." In fact, two thousand years ago, there was originally a place in the deep mountains of the Qinling Mountains that produced basha wood, and the craftsmen who built the mausoleum also traveled all over the north and south of the river to find this kind of wood. In view of the rarity of basha wood, after the construction of the mausoleum was completed, in order to prevent future generations from knowing the excellent qualities of this wood, I ordered the burning of the wood. As far as I can see, the basha wood of the South American rainforest that you are talking about, I am afraid that the tree species also flow out from here. ”

"No, South America is thousands of miles away, how can tree species get by." Ou Zhou denied.

The First Emperor smiled: "People can't get by, the birds in the sky can, and the migratory birds migrate every year." Over the past 2,000 years, Ju Zhen has observed that there are no less than 100 species of migratory birds from the southern hemisphere inhabiting the Qinling Mountains alone. Every late autumn disappears, and spring flies again. ”

Ou Zhou smiled: "I didn't expect His Majesty the First Emperor to observe so meticulously. It is very likely that migratory birds will be planted with trees. Migratory birds play an important role in the reproduction of many plants on the earth. ”

Empress Zetian praised: "His Majesty the First Emperor is really wise, and even such details can be analyzed, and His Majesty is really worthy of being the first emperor of the ages." ”

The First Emperor said humbly: "In the two thousand years since I died, in addition to confessing my sins in life every day, I have seen many birds on the Qinling Mountains, tweeting every day, flying up and down freely, feeling emotional, and making more observations." ”

Empress Zetian praised: "I can't imagine that His Majesty the First Emperor is so careful with nature, but I am afraid that contemporary botanists are not as knowledgeable as you in this regard!" ”

His Majesty the First Emperor smiled and said, "Hahaha, I am also idle and happy." ”

Ou Zhou said curiously: "Your Majesty the First Emperor, the legend of the world is that in the mausoleum of His Majesty, mercury is used as the carrier to build a lake, and the coffin is a boat on it, imitating the sun running in the sky, in the east in the morning, in the west at dusk, day and night rotate, all the time. Tonight, the mausoleum is far bigger than the legend. However, with the power of modern science and technology, it is not easy to prepare 30,000 tons of mercury. But I don't know what method Your Majesty used to prepare so much mercury? ”

The First Emperor laughed and explained, "Speaking of which, you probably don't believe it, strange things in nature can always be encountered by me. Because of my delusional desire for immortality, I took an overdose of the elixir refined from cinnabar, which eventually led to the death of mineral poisoning. Mercury comes from cinnabar. In order to find the rich reserves of cinnabar mines, alchemists traveled almost all over the country. Coincidentally, later, mercury ore was found under this lotus peak, and the enrichment of mercury content reached 2.5%. It is well known that mercury is commonly found in cinnabar, chlorosulfur and mercuro-antimonite ores and other minerals, with cinnabar being the most common. Mercury ore was formed during a new orogeny, and Lishan was formed during a new orogeny. When cinnabar is heated in flowing air, the mercury in it can be reduced, and when the temperature is lowered, the mercury condenses into mercury, which was the most important way to produce mercury 2,000 years ago. ”

The First Emperor pointed to the mercury lake below and said with a smile: "This mercury lake is to dig cinnabar ore to make mercury, the day the lake was completed, 30,000 tons of mercury into the lake for a week, the volatile gas will push the pavilion into the air." ”

Ou Zhou and Jiang Yang glanced at each other and couldn't help but smile: "His Majesty the First Emperor is not only outstanding in his martial arts, but even the various science and technology he has are also outstanding in today's world. It's no wonder that such a huge underground project was created! ”

Jiang Yang said with a smile: "His Majesty the First Emperor is not only different from ordinary people in terms of martial arts and science and technology, but even in terms of dedication and affection, he is not inferior to anyone in all dynasties. ”

Empress Zetian smiled and asked, "How do you say this?" ”

Jiang Yang explained: "Legend has it that His Majesty the First Emperor built Afang Palace because he fell in love with a girl named Afang when he was a proton in Zhao State. After returning to China and ascending the throne, he wanted to marry the girl from Afang, but he was opposed by the ministers led by Lü Buwei. At that time, His Majesty the First Emperor made a lot of fanfare to build a house, which can be seen in the depth of affection. ”

The First Emperor sighed and said: "I can't look back on the years I was a proton in the Zhao Kingdom, and I was repeatedly bullied by the Zhao people. After I ascended the throne, I missed the innocent feelings of my youth very much, and I wholeheartedly wanted to marry Miss Afang, but who wanted Lü Buwei to interfere and try his best to prevent it, so that I could not fulfill my wish. To this day, that relationship still haunts my heart all the time. ”

Empress Zetian sighed: "It turns out that with the domineering spirit of the First Emperor, there are many unsatisfactory things. Sure enough, every family has a scripture that is difficult to read! ”

The First Emperor smiled and said: "If you are like you, the Empress of Heaven, her life is full of emotions, her achievements are outstanding, her children and grandchildren are multiplied, and she will die a good life." It can be a model for the emperors of all dynasties. ”

Empress Zetian sighed: "His Majesty the First Emperor only knows one of them, and he doesn't know the other. When I was exiled to the White Horse Temple as a talented person of Taizong, I felt that the world was difficult and dangerous, and I almost collapsed. If it weren't for the time to run and soar into the sky, who would remember that there was a talented person Wu Meiniang back then? ”

The First Emperor nodded, and just when he wanted to say something, he suddenly paused and said with a smile: "There are a lot of Xiaoxiao outside, and they are fighting the idea of the tomb of me." Shall we go out and have a look? ”

Ou Zhou and Jiang Yang said happily: "We just want to see what tomb robbers look like?" ”

Empress Zetian smiled and said, "For more than a thousand years, I have seen a lot of this kind of thing. At first, I was a little worried, but later I saw that the tomb robbers were desperate and couldn't do what to do, but I thought it was very interesting. Let's go out and see what this gang of grave robbers are doing tonight. ”

The First Emperor waved his sleeves and took the lead in flying upward.

Ou Zhou and Jiang Yang followed, and Empress Zetian followed closely.

In this sealed space, the vapors volatilized by mercury are like still water, which creates both resistance and great buoyancy.

Just like a person in a swimming pool, if the body does not move, it will stand still and fall, move slightly, the buoyancy will increase, and the body will naturally float upward.

When approaching the top of the Lotus Peak, the First Emperor recited the words in his mouth: "The gate of heaven is open, the gate of the earth is closed, and I bow down to open the door in person." ”

After speaking, the crack at the top of the lotus peak suddenly opened up.

A group of four spirits left the mausoleum, and under the guidance of the first emperor, they came to a place at the foot of the mountain.

At this moment, it is three o'clock in the morning, all the sounds are silent, the wilderness is silent, the crescent moon is sinking in the west, and the breeze is slow.

Under the guidance of the First Emperor, I saw five or six sneaky tomb robbers who were doing what kind of rat theft and dog theft.

The First Emperor chuckled and said, "In recent days, these tomb robbers have come almost every night and have been wandering around Lotus Peak for half a month. Now they are in a position no more than fifty meters from what they call the entrance of the tomb. Obviously, it belongs to the category of more occupations. ”

"Your Majesty the First Emperor, how did you know about the arrival of the tomb robbers?" Ou Zhou is puzzled.

"The ancients had the wisdom of the ancients, and when the mausoleum was built, various trigger devices were set up. This is very similar to the surveillance equipment of modern people. If a tomb robber comes, a little more professional, he will touch the devices. But ordinary people or animals would not touch that kind of alarm device. ”

Ou Zhou became more and more puzzled: "Your Majesty the First Emperor, why is this?" ”

The First Emperor laughed and said, "Professional tomb robbers, they will use astrological and compass positioning and then use tools such as probe shovels to explore. As a result, those devices will inevitably be triggered. Ordinary people don't have those behaviors, and as for beasts, they don't have them. ”

Ou Zhou and Jiang Yang glanced at each other, nodded and praised: "It's really amazing, no wonder many of the techniques of the ancients can't be cracked by today's scientific community, it's really extraordinary." ”

Empress Zetian smiled and asked, "When encountering this kind of tomb robber, how does His Majesty the First Emperor usually deal with it!" ”

"Sometimes it's fun with them, but most of the time, it's dismissive."

Empress Zetian smiled and said: "In my Qianling, if you encounter more professional tomb robbers, they will encounter the strange phenomenon of sudden changes in celestial phenomena. In fact, the reason is the same as the trigger device of the First Emperor's Mausoleum, once they trigger the setting device, abnormal celestial phenomena will appear. And it is by no means a coincidence as later people speculated. ”

Ou Zhou and Jiang Yang glanced at each other, nodded, and said with a smile: "We finally figured out the key. Later generations passed on this miracle, but it turned out to be an inevitability in chance. However, if it weren't for the whims of the designers and builders, this anomalous celestial phenomenon would not have been possible. ”
