Rong Ling was rather humane.

But the more Liu Wei thought about it, the more he felt that this method was feasible. She suddenly stood up.

Rong Ling pressed down on her eager hands and took a deep breath, then sighed: "I'm wet, but I really can't sew it back."

Hearing that, Liu Wei obviously hesitated for a moment, but in the end, her rationality was still broken by her desire to search for the truth!

She poured water over all the papers on the table and began to read them one by one.

A quarter of an hour later, she sat down in disappointment and muttered, "It's not water."

Then he looked up again.

Rong Ling stood on her back, her temples throbbing with pain.

Liu Wei threw caution to the wind and lit up the candle, causing it to soften and bake close to the candle. After burning it for a while, the word "stealth" did not come out, but it left a burn mark, and almost burned up.

Rong Ling blew out the candle and pulled Liu Wei who was standing far away, then said: "I'm going to the bookstore to buy a new book, stop messing around."

Liu Wei nodded with a complicated look on her face and sat in her chair to think.

Rong Ling was worried that the moment she stepped out of the door, she would burn the house down. Before she left, he would also take the candles with him.

When Rong Ling returned, she saw that Liu Wei was still sitting at the same spot, but her eyes were still far away, staring at the pages on the table.

He passed the newly bought《 Diamond Sutra》 to her. Liu Wei took it and casually flipped through two pages, but suddenly stopped: "This … It's not the same. "

Rong Ling looked over, but did not see any difference.

Liu Wei walked to the front of the table, picked up a half-dried page, compared the new book, and said: "The first version is an ink, the second is a lead, Grandfather's book, is made of lead."

When Rong Ling heard this, she looked at it. The new book's font color was dark, it was ink black, the words were clear, the old books' font color was light, grey, the words were also blurry. Looking at it from this way, the two books' printing materials were indeed different, but what did this mean? Liu Wei said: "For these kinds of engravings, the ink imprint is much easier to form and much more durable, there are very few engravings on the lead, which also means that at that time, this book was also made using the lead imprint, but since the ink imprint is the more commonly used ink used by the various bookshops, why would they use the lead imprint on this book? Could it be that ink-jet printing was more prevalent at that time? However, that's not right. The Residence of Yun also has many ancient books and books.

After reading a few books, some old books started using ink seals or handwritten copies. In other words, a few decades ago, ink seals were more common in distant lead imprints. The only reason why this booklet used lead seals was because of the cost. "

Rong Ling shook her head, rejecting her words: "Ink is cheap, lead is expensive."

Lead is a kind of ore, is also a kind of medicinal material, the ancients have said, its weight is solid, its sex is slippery, its color is black, inside to the kidney.

In the world of apricot trees, lead is often used as medicine, and because of its great effect, lead has a wide range of uses, and the ink that can be found everywhere at a high price is much more expensive.

However, Liu Wei smiled. "Under normal circumstances, lead would indeed be expensive, but what if it comes from nearby lead mines?"

Rong Ling was startled. "You mean …"

Liu Wei was enlightened, and could not help but laugh: "There is no map in this book. It is originally a map, and as long as one knows the important locations of Immortal Yan Nation's plentiful lead mines, they can determine the origin of this book."

Rong Ling got up and walked out.

A map of the country was no small matter. A normal book shop had no right to sell such a map. Ordinary families would not dare to draw such a map in private, but the king's mansion must surely have one.

When Rong Ling left for the Duke's Palace, she did not stay idle either. She carefully dried the wet pages of the book, folded them into a pile, and arranged them according to the order of the new books.

The two volumes had different fonts and colors, but the contents were exactly the same.

Liu Wei was unable to find any differences between the words, she could only focus on the paper and the sculptor.

To create a book engraving was not a child's play. First, it required a large enough engraving, and the author often used his usual handwriting to carve it out.

This was a new book written in ink, and the engraver had noted it on the title page. It was the descendant of the current engraver, and he used the avatar style.

As for the old book, the title page had the author's name, but it only had one code name, 'Blue Luan Ju'.

The Cyan Orchid Flower was a branch of the Orchid Flower, and was distributed between the Northwest and Northwest. Liu Wei boldly assumed that it was the sculptor or someone from the Northwest?

In addition to the engraver, the last page of the lead-printed book was also engraved with a red seal. The title of the book was "Understanding the meaning of the heart, the meaning of the Great Perfection", which was the summary of the Diamond Sutra. It was not inappropriate for the book to leave behind a red seal, but the red seal was used with a small amulet.

When the entire text was transformed into an italic figure, the small seal seemed somewhat strange.

While Liu Wei was still thinking about the details of the seal, Rong Ling had already returned with a scroll.

He opened up the scroll and it was indeed the picture of the Immortal Swallow Mountain.

When he borrowed the map, Rong Ling had asked ahead of time. Now that they had started, he directly pointed to Sky Stone State on the left and said: "An Yi County, Lai Cheng County, and the two counties are all places where lead mines are produced. Also, Golden East County in Ting Jiang Prefecture, there is also a portion of the stone mine distribution."

Liu Wei pointed to the name carved into the title page of the old book and said, "Sky Stone Region and Pavilion River Region are both located in the northwest. This Blue Orchid Residence's Blue Orchid also originates from the northwest."

Rong Ling frowned, her expression did not look good: "Sky Stone Region occupies over a thousand acres of land, An Yi County and Lai City County each occupy half of the land, not to mention Ting Jiang Prefecture's Jin Dong County also occupies several hundred mu of land. If we continue to search like this, we will still be looking for a needle in the ocean."

Liu Wei then pointed to the red badge at the end of the page: "If you can find the person who carved this, then the scope of the carving will shrink a lot."

A vast sea of people filled the vast world. It would not be an easy thing to find an Inscription Craftsman in the two provinces. Liu Wei also knew that it was not easy to find, so she continued to exclude him: "The Diamond Sutra is a famous Buddhist book, these kinds of books, are usually published by the big book shop, and the seals used by the big book shop are definitely not carved by the small vendors, in these past fifty years, I have found the two prefectures' most famous sculpting experts' rankings, and I think I will be able to find more clues."
