Tang Ding's knowledge of ancient calligraphy and painting is also much more than Qin Yujie's.

In the past two years, although Tang Ding has read history, he has not forgotten to learn the words found in history, because to study history, we must first study the words that record history, and don't forget Tang Ding's teacher, Shu Hai Shulao, who is the only surviving in the country and is known as the double masterpiece of calligraphy and painting.

Tang Ding carefully looked at the big seal characters on the book.

The big seal is earlier than the small seal of the text, the small seal is after the unification of the six countries of Qin Shi Huang, the promotion of the text after the implementation of the "car on the same track, the book with the text" in the country, before this, the six countries have their own words, although the writing is different, but the academic community has become the big seal.

The big seal is more difficult to recognize than the small seal, because there are many ways to write a character depending on the region.

The words on this silk book, if Tang Ding is not mistaken, are talking about the water of eternal life and the jade of eternal life.

If you want to live forever, you can only get the water of eternal life and the jade of eternal life. The jade of eternal life, Qin Mugong has already obtained, he expects to get eternal life, and wears it with him, but the water of eternal life that can live forever, Qin Mugong has been looking for it everywhere but has not found it.

This is what this calligraphy and painting will be.

Tang Ding continued to open the handwriting of the silk painting, and found that there was a description of the water of eternal life on the second page of the silk painting, but there was only one sentence: the legendary water of eternal life, even a bronze sword can float on it.

In addition, the silk painting also records that Qin Mugong's great achievements at that time were reconciled with the Jin Dynasty and subdued the Jin Dynasty.

Later, there was also the story of a large-scale westward expedition to the Rong tribe.

Although Tang Ding couldn't recognize all these handwritings, he could still see the general meaning.

Of course, Tang Ding didn't show half of Qin Yujie, "I can't understand these things for a while, I'll go back and take a look." ”

"How many days will it take?" Qin Yujie hurriedly asked.

"Why do it take more than ten days, and I have to go to Shaanxi tomorrow. ”

"Shaanxi, what are you going to do?" Qin Yujie's first impression was that Tang Ding was going to go to the tomb of Duke Qin again because he had seen his calligraphy and paintings.

"Shall I go to Shaanxi for a tour? Terracotta Warriors, Huaqing Pond, Huashan, where can I go?"

Qin Yujie heard the displeasure in Tang Ding's tone, and she hurriedly changed her words, "I didn't mean that, I mean that if you want to go to the tomb of the Duke of Qin, it has been sealed and guarded by armed police, and you can't enter at all." ”

"Oh, I'm not going to the tomb. ”

"Okay, I'll wait for you to come back. Qin Yujie took the opportunity to put away the jade of immortality.

The moment he closed the crystal box of the Jade of Immortality, the gloomy aura that permeated the café suddenly disappeared.

It was like going from winter to summer.

On the plane to Baoji, Tang Ding turned his mobile phone into airplane mode and flipped through the photos that Qin Yujie sent him.

The narrative in the Qin people's text is very brief, basically one sentence to describe the facts clearly, and never use the second sentence.

However, this also relatively increases the difficulty for future generations to understand and scrutinize.

"Sir, may I ask what you have to drink?" the stewardess asked Tang Ding politely.

"Let's have a glass of water. ”

"Okay, please wait. ”

After the stewardess asked Tang Ding, she picked up the big kettle on the cart and poured water for Tang Ding, Tang Ding noticed that a small insect suddenly flew in, fell into the water without warning, floated on the water, and swam around.

"Sir, I'm sorry, I'm sorry, I'll change your glass right away. ”

The stewardess was about to take the cup back and give Tang Ding a new one.

"Don't move, just ask for this one. ”

Tang Ding's words made the flight attendant mistakenly think that Tang Ding was going to find fault, "Sir, I'm sorry, I didn't mean to." ”

Tang Ding didn't answer the stewardess's words because two things suddenly came to mind at this time:

First, the water of eternal life mentioned in Qin Mugong's silk book can float copper swords.

What kind of water can float a copper sword? Mercury, of course. Anyone who has studied chemistry knows that the specific gravity of mercury is more than eleven times that of water, and the specific gravity of copper is less than nine times that of water, so copper must be floating on it in mercury.

Second, he remembered Sima Qian's description of the scene in the tomb of Qin Shi Huang.

Sima Qian's "Historical Records" recorded: "The first emperor succeeded to the throne at the beginning, wore the Lishan Mountain, and merged the world, the world sent 700,000 people, wore three springs, and went down to the copper to the coffin, and the palace was full of strange and strange artifacts. Let the craftsman make a crossbow arrow, and if there is a nearness, shoot it. With mercury as the rivers and seas, the machine is instilled, with astronomy and geography. With mermaid paste as a candle, the one who will not be extinguished will last for a long time. ”

The previous mentioned is the construction of the tomb of Qin Shi Huang, in which there is a sentence "under the copper and to the coffin", which shows that the coffin of Qin Shi Huang is likely to be made of pure copper.

"Mercury is a hundred rivers and seas, with astronomy at the top and geography at the bottom. This sentence says that the tomb of Qin Shi Huang has the sun, moon and stars on it, and there are mountains and rivers below, and the rivers are instilled with mercury.

The function of this mercury is to prevent tomb robbery and embalming corpses. Ancient Taoist priests mostly used mercury to make pills, so mercury should have an immortal effect in the minds of the ancients.

Combining these two points, the water of eternal life that can float the copper sword recorded in the silk book in the Qin Mu Cemetery should be mercury.

Tang Ding thought more far-reaching:

Qin Mugong begged for immortality but couldn't, because he only got the jade of eternal life, but he didn't get the water of eternal life. And Qin Shi Huang also asked for immortality, he got a large amount of eternal water, but why Qin Shi Huang did not have immortality, is it because he did not get the jade of eternal life.

Ancient mercury was unusually scarce, and it was not easy to refine, and Qin Mugong lived in the northwest, so he had no way to find mercury, so he did not get the water of eternal life.

The people of the world do not understand how Qin Shi Huang was confused by some scholars because of his great talent and great talent, and how could he be confused by some scholars when he possessed the cultural and martial arts to unify China? Didn't he know that immortality was just a beautiful fantasy of mankind? Before Qin Shi Huang, the history of mankind was also very long, so didn't he know that birth, old age, sickness and death were the normal feelings of human beings?

But why did Qin Shi Huang pursue immortality so persistently?

The world believes that immortality is impossible. But Tang Ding has another opinion, or speculation: if Qin Shi Huang's pursuit of immortality is not groundless, but real, then it is understandable why Qin Shi Huang is so obsessed with the pursuit of immortality. It is also understandable that when Qin Mugong died, he would keep the jade of immortality by his side and carry it with him, and in his tomb, he would record everything about immortality in a grand manner.

In the history of the pre-Qin period, it seems that this immortality was passed down from generation to generation in the royal family.

Of course, if it was only passed down from generation to generation, Qin Shi Huang could not be so blindly believed, he must have seen other legends, or true stories, true stories about immortality.

However, Qin Shi Huang did not find the Jade of Eternal Life, so he could not live forever, and it is because of this that Qin Shi Huang brought so much of the water of eternal life into the tomb.

Waiting, Tang Ding suddenly thought of a record he had read in history, which was about an even more mysterious kingdom in ancient China, a mysterious woman.

Qin Shi Huang found mercury in this mysterious kingdom, which was called Ba. And that mysterious woman, Tang Ding also remembers very clearly, her name is Qing.

At the beginning of the Western Zhou Dynasty, Zhou Tianzi divided seventy-one vassal states, and Ba was one of these seventy-one vassal states.

This woman called Qing is a widow, known as Widow Qing, and the family of Widow Qing has been engaged in the mining of Dan sand ore for generations, and she is rich enough to rival the country.

Dansha, i.e. mercury sulfide. It can be used as a medicine and dye, and can also be used to refine mercury.

It is recorded in the book that the mercury obtained by Qin Shi Huang was obtained from the widow Qing of this Ba country.

The flight attendant looked at Tang Ding quietly looking at the flying insects swimming in the water cup, without saying a word, she was a little angry, and said in her heart, didn't this person want to use this cup of water to enter the flying insects to complain about herself, right?

"Sir, may I change a glass of water for you?"

"Oh, oh, well, just got distracted. ”

Tang Ding handed the water to the flight attendant, who poured him another glass, and then pushed the car away quickly.

Tang Ding drank the water and thought of something: If the water of eternal life that Qin Mugong asked for but couldn't get was in the country of Ba, then did this country still have any connection with Qin Mugong?

It stands to reason that Qin Mugong should not have known that Pakistan had the water of eternal life at that time.

But is this water of eternal life really mercury?

If the water of eternal life is really mercury, then how can the water of eternal life and the jade of eternal life be used to truly achieve eternal life?

This is another problem.

Mercury is easy to get, and mercury can be obtained casually in modern society, but how to use it?

Tang Ding also thought of a question, if the dead Qin Mugong knew that the water of eternal life was mercury, would he know that mercury could be obtained casually now? If he knew, would he crawl out of the grave angrily because he lost the chance of eternal life?

It was definitely not possible to climb out, because he had already turned into ashes and scattered.

"Huh. Tang Ding thought about it and laughed.

"You are smiling like this, did you think that you could soak in the beautiful flight attendant just now?" a person next to him asked Tang Ding with a smile.

Tang Ding turned his head and saw that he was a very handsome young man, and he smiled and winked at himself, as if he thought he had guessed his thoughts.

"No, I'm glad I didn't. Tang Ding also made a rare joke.

"And, you just brag about it, the flight attendants on the plane are all masters who have read countless people, you think you can soak if you want!" said the young man.

"That's why I'm glad I didn't. ”

It was probably because of the news of the Jade of Eternal Life and the Water of Eternal Life, which had been hanging in the air, that he had a little confidence in finding the whereabouts of his parents, so Tang Ding was in a good mood and joked with this young man who was younger than him.

"That's it, don't brag, if you can get this flight attendant's WeChat account, I'll treat you to a meal. ”

Hearing the young man's words, Tang Ding glanced at him and knew his thoughts.

This young man used the agitation method on himself, it turned out that he wanted to soak in this flight attendant!
