"What's wrong?" Chen Shi could see at a glance that Zheng Zheng's face was wrong, and asked with a smile.

Zheng Zheng shook his head and said with a smile: "It's not much...... Tell me where this thing came from, and I'll hear it. ”

Chen Shi was surprised: "Isn't this just waiting for your appraisal?

This question is very layman's, Zheng Zheng has no choice, he can only popularize his knowledge: "Although I have to identify this thing, but before I appraise it, you have to tell me the information you know, and after I know this, I will compare it with the results I have obtained, and you will know whether the book is true or fake, and how much it is worth." ”

"So that's ......" Chen Shi nodded, took out a stack of A4 paper printed materials from his briefcase, and handed it to Zheng Zheng. He clicked on the book "Yunhe Essays" and said: "This is what I picked up at an old book stall, and the stall owner said that this is an essay record of a Ming Dynasty imperial physician named Xu Zhong, which records a lot of things about the Ming Dynasty royal family. I didn't care about it at the time, but later I checked some information and did find a record about this Xu Zhong, but the approximate record is only one hundred and eight crosses, and I simply wrote his life, and there is no other valuable information. These,"

Chen Shi pointed to the stack of A4 papers and said, "This is the information I found before, you can take a look." There are materials about Xu Zhong and Ming Dynasty printing, as well as materials about Ming Dynasty books, which you can use as a reference. ”

Zheng Zheng listened to Chen Shi while looking at the stack of materials, but he only glanced at it. The characteristics of books and printing characteristics in the Ming Dynasty, including the choice of paper, Zheng Zheng knows them in his heart, so he doesn't need to look at this. Besides, Chen Shi has already bought this ancient book, which proves that the characteristics of this ancient book are in contrast with these materials, and there is no need for reference.

As for Xu Zhong's information, Zheng Zheng just knew it in his heart. You must know that the ancients used ink very concisely, and a hundred and ten words can summarize a person's life, and there is really no useful information to be seen.

However, there is a little information on it that arouses Zheng Zheng's curiosity, according to the information, Xu Zhong was the imperial doctor in the palace of the Ming Dynasty back then, and his medical skills were exquisite, and he happened to serve Zhu Changluo in the years when he was in the palace, that is, Emperor Taichang of the Ming Dynasty.

Most of the emperors of the Ming Dynasty were short-lived, and it can be said that few of them started and finished well, and the few who lived a little longer also had endless anger. And this Taichang Emperor was the best of the short-lived emperors, and he stopped eating after twenty-nine days on the throne. And it was precisely because of his death that there was the Red Pill case, one of the three major cases in the late Ming Dynasty.

Zheng Zheng had read the information about these three major cases when he looked at the relevant materials of the Ming Dynasty before, and he was embarrassed by the red pill case. Emperor Taichang was also unlucky, as soon as he ascended the throne, he began to pamper the beauties, coming every day and night, simply put, in addition to sleeping, he did it, and he estimated that he wanted to have a good time with the emperor's addiction.

As for this Emperor Taichang, his body and bones are like that, and he was also happy with wine before he ascended the throne, and his body has long been hollowed out.

The body is hollowed out, and there is naturally some dissatisfaction between the sheets, although the emperor doesn't have to care about whether those women are comfortable or not, but the emperor also wants to save face, isn't it?

So Emperor Taichang began to eat jelly beans like eating **, eating dry and dry, eating dry and dry...... Finally, one day, he fell ill. At that time, Cui Wen, the eunuch who was also in charge of the imperial pharmacy, took a dose of laxative, and Emperor Taichang could be regarded as suffering a crime after eating it, and he had diarrhea thirty or forty times in a row.

As the saying goes, a good man can't stand three bubbles, what kind of concept should it be thirty or forty times? Emperor Taichang directly pulled half dead.

If it is light, then forget it, the key is that at this time, Li Kezhuo, the Cheng of Honglu Temple, offered a "red pill" to Emperor Taichang. Emperor Taichang took a course of treatment with the attitude of trying it out...... No, after one pill, I feel refreshed.

After finishing less than half a day, I ate another pill, which is considered to be a complete calf, and Emperor Taichang kicked his legs and settled the account.

There are many suspicious points in this red pill case, whether it is a eunuch taking laxatives or Li Kezhuo entering a red pill, there are many articles to be done. If you want to say that the responsibility is on these two people, then you can't say that; if you don't say that it is not on these two people, then Emperor Taichang is indeed because he has paid the account after eating the medicine offered by the two, so this is a confused account, and it is not clear. So later, the two of them were simply dealt with, even if the matter was closed in a mess.

And what is the truth of the Red Pill case, there was no conclusion at that time, and later generations did not have a definite conclusion, so the Red Pill case became a historical unsolved case and placed there.

If this Xu Zhong served Emperor Taichang back then, there are many things that cannot be written on the surface, and he is likely to write them in his essays. If you can know the truth about the Red Pill case from this essay, it can be regarded as a historical unsolved case. At that time, the value of this "Yunhe Essay" will also become more precious because of its research value.

However, there is another premise for this, that is, it must be able to prove that this "Yunhe Essay" is indeed true, otherwise it is meaningless to say anything.

Zheng Zheng put aside the information in his hand and beckoned Bai Xiaoxue to bring a pair of gloves and a steel ruler. Zheng Zheng put on his gloves, but he was not in a hurry to get the book, but took the steel ruler, carefully poked the steel ruler into the gap between the pages, and then slowly used the steel ruler to open the pages.

The most difficult to preserve in antiques should be calligraphy and painting, this thing is afraid of water and fire, if you are not careful, it is over, sometimes even if the temperature is too high or the humidity is too high.

And after so many years, this kind of paper book is not sure what it looks like inside, it is possible to open the pages with a little more force and break the pages.

When identifying this thing, everyone has their own tools, and Zheng Zheng likes to use this steel ruler to turn the pages.

Counterfeiting of ancient books is actually quite difficult, because experienced appraisers can draw correct conclusions from paper. However, this does not mean that the past cannot be blinded, as long as the operation technology is appropriate, the paper ready for counterfeiting can be soaked in the sun, rinsed and other steps, and the desired effect can be achieved.

If it is a painting with a brocade cloth backing or silk backing, then you can start from this aspect if you are not sure about the paper. But paper books are different, and if you are not sure about the paper, this identification is much more difficult.

And when Zheng Zheng was appraising this "Yunhe Essay", he simply skipped the step of paper identification.

Although Zheng Zheng's identification ability is not bad, but compared with the technology used by others to make a living, Zheng Zheng feels that he is still a little worse - of course, if you use a bronze balance, it will definitely not be so troublesome, but Zheng Zheng now knows the harm of using a bronze balance, even if you encounter a more uncertain situation, Zheng Zheng can not use it as much as possible, not to mention this kind of thing that may not necessarily have any benefits.

Since it is difficult to identify from the surface, let's start with the content. If this ancient book is fake, then it is possible to find some clues in its contents.

The handwriting of this "Yunhe Essay" is a little unclear, and the black ink color has become faint, but I can see clearly what is written. Zheng Zheng glanced at it a few times and nodded slightly, it is difficult to say how this Xu Zhong's medical skills are, but he writes a good hand, and the words written in block letters are full of energy, and the layman probably thinks that it was printed by a printing press.

Zheng Zheng flipped through a few pages, and they were all swept over at a general glance. This Xu Zhong's notes are like running accounts, nothing more than when he saw someone, what medicine he used, or something to do and made a memo or something, or who was punished and he sent something to sigh or something...... Anyway, it's just that little thing, and there's nothing to look at in detail.

After turning a few pages in a row, Zheng Zheng didn't speak, and there was no expression on his face. Chen Shi was drinking tea and waiting, but he was not in a hurry. Maybe it's sitting bored, or maybe it's watching the beauty move, Chen Shi also said a few words from time to time Bai Xiaoxue.

This situation fell in Zheng Zheng's eyes, Zheng Zheng had no trace on his face, but he was happy in his heart. Bai Xiaoxue is not in a good mood today, although Chen Shi also looks like a dog...... Uh, it looks pretty good anyway, but it's his fault to provoke Bai Xiaoxue at this time.

Sure enough, Chen Shi also responded to Bai Xiaoxue's conversation, but her tone was indifferent, and her expression was so unwelcome. Chen Shi chatted with her for a few words, and he was a little embarrassed, so he stopped talking to Bai Xiaoxue.

Zheng Zheng was secretly amused, and took his mind back to this notebook. He flipped two more pages and was caught by a short quote: "...... Concubine Jing was infected with wind disease, the more serious she became, the weakness of the medicine stone, and she died in the middle of the winter moon......" followed by his induction and summary of Concubine Jing's illness, and pointed out that there was a problem with the Taiyi medicine at that time, which is almost the same as hindsight.

Such a passage was meaningless, but Zheng Zheng just looked at this passage and was distracted. After a while, he withdrew his gaze and patted his head with a frown, a look of confusion.

"What?" Chen Shi saw that Zheng Zheng's expression was wrong, and immediately asked.

Zheng Zheng shook his head slightly and motioned for Chen Shi not to speak. He placed the book on the edge of the table, then stood up and took a few steps back, looking at it from a distance.

Chen Shi looked at Zheng Zheng and looked at the book again for some reason, he really couldn't figure it out, he couldn't see the reason when he looked at it at a close distance, could he see the problem from a distance.

Zheng Zheng frowned for a while, and then his brows stretched. He took off the gloves in his hand, took out a cigarette and lit it, and said to Chen Shi: "Fake - if you spend more than fifty yuan to buy it, it will be a loss." ”
