Rong Ling is more human.

But the more Liu Wei thought about it, the more she thought it would work. She suddenly stood up and was about to go out.

Rong Leng grabbed her and pulled her back.

He is powerful, Liu Wei is cold and unprepared, he is dragged to stagger, his body is askew, and he bumps the desktop.

On the table, there is also half of the tea that Rong Ling had drunk before. The water cup shakes and the water pours out. All of a sudden, the scripture paper on the table is soaked.

"Bad." Liu Wei frowned and cried. She picked up the paper and tried to dry it. Suddenly, she was so blessed that she looked at Rong Ling.

Allow edge a Leng, in the heart gush out a foreboding feeling.

Sure enough, the next moment, Liu Wei said, "I haven't tried water and fire yet. Maybe it's invisible words. Come here and drench all these papers."

Rong Leng pressed her eager hand, took a deep breath and sighed, "it's wet, but it can't be sewed back."

Liu Wei hears the words, obviously has a moment's hesitation, but in the end, the reason is still broken by the desire to pursue the truth!

She poured water on all the papers at the table, and then distinguished them carefully.

A quarter of an hour later, she sat down again disappointed and whispered, "it's not water."

Then he raised his head again: "there is only fire."

Rong Ling is standing behind her, the pain in her temple.

Liu Wei burst out, lit a candle, and made a piece of soft warp paper. Then he baked it close to the candle. After burning for a while, the invisible words did not come out, but they burned a scorch mark, which almost didn't burn up.

Rong Leng blew out the candle and pulled Liu Wei to stand far away, saying, "I'll go to the bookstore and buy a new book. Don't bother."

Liu Wei nodded with a complicated face and sat in the chair thinking.

Rong Leng is not at ease. Afraid of going out of the gate, Liu Wei burns the house. Before leaving, he takes the candle with him.

When Rong Ling came back, he saw Liu Wei still sitting in the place before him, but his eyes were far apart, staring at the pages of the table.

He handed her the newly bought Vajra Sutra. After Liu Wei received it, he flipped over two pages at will, but suddenly he said, "this It's different. "

Rong Leng looked, but did not find any difference.

Liu Wei went to the desk, picked up a half dry page and compared it with the new book, saying, "one is in ink, the other is in print, and my grandfather's book is made of type."

Let Leng smell the words and compare them. The font color on the new book is darker, black and clear. The font color on the old book is lighter, gray and fuzzy. Just look at it. The printing materials of the two books are different, but what can it say?

Liu Wei said: "at present, books and ancient books are mostly printed by carving, that is, first carve out the model books, then print on clean paper, and finally bind them into volumes. For this kind of carving, ink printing is easier to shape than lead printing, and it is also more solid and durable. There are few print engravings. Grandfather's book of scriptures has existed for many years, that is to say, at that time, this book was also made of lead Printing plate, but since ink printing is a more commonly used printing solution for various bookstores, why should this book use lead printing? Was ink printing more popular than lead printing at that time? But that's not right. There are many ancient books in Yunfu. I have read several of them. Some of them are old books. They are all printed in ink or by hand. That is to say, decades ago, ink printing was far more popular than lead printing. The only reason I can think of is the cost. "

Rong Ling shook her head and rejected her saying: "ink is cheap, and lead is precious."

Lead is a kind of ore and also a kind of medicinal material. According to the ancients, its body is heavy and solid, its nature is slippery, its color is black, and it can pass through the kidney.

Lead is often used as medicine in the apricot forest. Because of its great effect and wide use, the price of lead is much higher than that of ink everywhere.

Liu Wei is a smile: "under normal circumstances, the cost of lead is indeed higher than that of ink, but how about living near the lead mine?"

Rong Leng is shocked: "you mean..."

Liu Wei felt suddenly enlightened and couldn't help laughing: "there is no map in this book. It is a map. Now you only need to know several important places where Xianyan country is rich in lead ore, and then you can judge the source of this book."

Let Leng get up and go out.

The border map is very important. Ordinary bookstores have no right to sell it. Ordinary people dare not draw it privately, but you must have it in the palace.

Rong Ling leaves for Rujiang palace, and Liu Wei is not idle. She carefully dries the wet pages, stacks them up, lists them in order, and compares them with the new books one by one.

two edition is as like as two peas, but the contents are the same.

Liu Wei can't find the difference from the words, so he has to work hard on the paper and the engraver.

It's not a joke to make a Book engraving. First of all, it needs a large enough engraving, and the engraver often uses his usual font to make engraving.

Ink version of the new book, engraver in the title page, is the next generation of engraver family, using regular script.But the author's name marked on the title page of the old type book only has one code name, which is called qinglanjuke. He uses italics.

Qinglan is a branch of orchid, which is distributed in two places in the northwest. Liu Wei's bold assumption is that the sculptor or or the northwest people?

In addition to the woodcarver and the end page of the printed book, there is also a red seal, which is written on the chapter as "knowing what you want, riding on the top". This is a summary of the Vajra Sutra. There is nothing wrong with the red seal falling from the Sutra, but it is a small seal.

When the whole engraving is in italics, the seal printing of Xiaozhuan seems a little strange.

While Liu Wei was still pondering the details of the seal, Rong Ling was about to return and brought back a long scroll.

Unfold the long axis, which is indeed the picture of Xianyan River and mountain.

When borrowing the picture, Rong Ling asked in advance. At this time, he pointed directly to the top left of tianshizhou, saying: "Anyi County, Laicheng County, both of which are lead ore producing areas. In addition, Jindong County of Tingjiang Prefecture also has some distribution of ore."

Liu Wei pointed out that the title page of the old printed book was carved as the name, saying: "Tianshi Prefecture and Tingjiang Prefecture are both located in the northwest, and the Qinglan among the Qinglan residents is also from the northwest."

The expression is not good: "Tianshi Prefecture covers an area of 1000 mu, Anyi county and Laicheng County account for half respectively, let alone Jindong County of Tingjiang Prefecture also covers hundreds of mu, so to find, is still looking for needles in a haystack."

Liu Wei pointed to the red chapter at the end of the page: "if you can find the engraver, the range should be reduced a lot."

It's not easy to find an engraver in two states.

Liu Wei also knew it was hard to find. She continued to rule out: "the Vajra Sutra is a famous Buddhist Scripture. Such books are usually issued by Dashu shop. The seals used by Dashu shop will not be carved by vendors. Find out the ranking of the most famous sculptors in the two states in the past 50 years. There should be more clues."
