Qian Yang couldn't find a way to take all the books away, so he decided to write down as much useful content as possible.

What kind of content is useful? Qian Yang's brain spun at an extremely fast speed, his spiritual sense flew through the almost boundless stacks of books, and the titles of books rushed through his mind.

"How to sell yourself in life", "How to get ahead in KTV", "How to conquer a beautiful girl" ......

"Poof, what are all these things?" Qian Yang was a little embarrassed.

"Huh, what is this?" Romance of the Three Kingdoms

"Romance of the Three Kingdoms? I'll give you 82 points for this translation!" Qian Yang wanted to laugh a little.

"How to dispose of the ashes of your predecessor"

"That's a good question!" Qian Yang shook the corners of his mouth.

"Drinking Your Own Urine to Cure Your Own Disease"

"Okay!

Qian Yang really didn't want to complain about the chaos of the publishing industry back then, the problem was that it was too difficult for him to find something useful from the vast sea of books.

Qian Yang gave up the blind search and calmed down to think about the direction. Speaking of which, the difference between the two eras is indeed too great, and it is not easy to find instructive knowledge from prehistoric books. What kind of economy, culture and the like, it has nothing to do with the immortal cultivation world. Not to mention any agricultural science, industrial technology, etc., the rules of heaven and earth have changed, and only spiritual power is the only direction of development. Philosophy and art may have some effect, but the meaning is also very limited.

"Where is the biggest connection between the two eras?" Qian Yang finally thought of this question.

There is no doubt that the biggest thing that the two eras have in common is that he Qianyang! A monster who has lived from prehistory to the present! Who else can connect millions of years before and after him?

"Huh?" Qian Yang's eyes lit up.

Qian Yang smiled bitterly: "The most able to connect the prehistory and the present are the ruins!"

Ruins are entire prehistoric areas that have been relatively well preserved in the catastrophe, and there may be a large number of prehistoric items in the ruins. And because of the breeding of spiritual energy and the change of the rules of heaven and earth, it is very likely that the items in the ruins will still be well preserved for millions of years. For example, Qian Yang himself, for example, the signboard, and for example, the paper books in front of him that have long exceeded their useful life, but are still barely recognizable.

And the most valuable item in the ruins is the prehistoric antique, Qian Yang has made several sums of money with his unobtrusive appraisal level by virtue of the advantage of rebirth, if he can improve his appraisal ability, won't he have to make a lot of money in the future?

Qian Yang finally found the right way, but is there any knowledge about antiques in this pile of books?

Just kidding! Dongliao City Library was one of the top municipal libraries in China at that time, and the number of books about the collection of books in the collection can definitely be compared to the number of trucks!

It was not difficult for Qian Yang to find books about antiques from this vast number of books. After the library purchases books, a cataloger will classify the documents, and attach the classification number to the books, and then arrange the books according to the book classification number.

Dongliao City Library is in accordance with the "Zhongtu Law" to classify the books and shelves, when the relocation of the year, it is also in accordance with the order of the shelves when packing, and then the cartons are stacked into the new library warehouse in turn.

"Zhongtu Law" is a book classification method based on subject classification, and most books of the same discipline are listed in one place. For example, books related to philosophy and religion will be classified as category B, books related to economics will be classified as category F, literature will be classified as category I, biological sciences will be classified as category Q, and so on.

Of course, there will be different degrees of subdivision for each book. For example, the well-known "Romance of the Three Kingdoms", if Qian Yang was to classify it, he would probably give a classification number of I242.4, I stands for literature, I2 is Chinese literature, I24 is a novel, I242 is an ancient to modern work, and I242.4 is a chapter hui novel.

Since books of the same kind are all stacked together, Qian Yang can easily find what he wants as long as he finds the category to which the collectible books belong.

It is easy to say, but in fact, in the specific classification process, the classification boundaries of many books are very blurred, and there will always be some differences in the understanding of categories by catalogers. Even if it is the same book, it is very common for two catalogers to be divided into two completely unrelated categories, so the book Qian Yang is looking for should be divided into many places.

So how do you look for it? There's no search engine here.

However, this is not difficult for Qian Yang, the layman may be confused about the classification number, but as an excellent librarian, book classification is the professional skill he relies on to survive, and there are traces of where a book will be assigned after all.

Qian Yang walked forward gently, for fear that the air flow brought by walking would break these books, and the first thing Qian Yang wanted to find was the location of the G books, which were cultural, scientific, educational, and sports books, and most of the books about collecting were under this category. Not far away, Qian Yang found a mountain of G-class books under a pillar. Picking up the numbers, Qian Yang easily found G894, which represents private collections, and many collectible books have been assigned here.

"Analysis of Gold and Silver Collections"?"Not bad!"

Qian Yang needs this.

"Notes on Collecting Ancient Coins", "Anecdotes on Collection", "Guide to Private Collections", ......

Qian Yang roughly swept through the books in the vicinity, removing the copies, and there were about 2,000 copies of a certain value. It's not a small task to write it all down.

Qian Yang didn't rush to record it, but left a mark next to this pile of books, and then continued to look for other classifications. Not far away is his next target: the G26. This classification number represents the museum and the museum business. There are many reasons why catalogers will assign some collectible books here, such as the emphasis on the content in the book, the provenance of the collection, the origin of the author, and so on.

"The Story Behind the Hidden Collection", "Practical Collection", "First Acquaintance with Jadeite", ......

Still leaving only a mark, Qian Yang continued to look forward, and in the corner not far away, Qian Yang found the target K85: Cultural Relics Archaeology, and next to it K86: World Cultural Relics Archaeology, K87 Domestic Cultural Relics Archaeology.

Looking at the place where the books were, Qian Yang shook his head, this part of the books was stacked at the bottom, and now they were completely soaked in water.

Flooding is not a problem, the problem is that the books have long been weathered and cannot be handled, and although the flow of stagnant water has not completely destroyed the books, it has also caused a lot of damage, and it is impossible to record them completely.

"It's a pity!" Qian Yang was a little distressed, sighed and continued to search.

Category F Books: Economics.

It seems that the economic category has little to do with the collection, but in the F category, there are also quite a few books that Qian Yang urgently needs.

F713.359！

This seemingly small classification number represents the auction, and most of the books related to the auction are distributed here, including the antique auction. For Qian Yang, a layman in the collection, it is already very unreliable to distinguish the authenticity of an antique by feeling, and it is even more marginal if he is asked to evaluate the price of an antique.

However, for the identification of prehistoric antiques, the evaluation of the price is the most important. Through its prehistoric price, we can roughly get the current spiritual energy content, so as to know how many spirit stones a thing is worth, and what kind of cultivator it should be suitable for.

In the previous secret auction, Qian Yang showed his skills, but in the end, all the bids were given by Zhou Lao, and Qian Yang couldn't even give the approximate range of the price. Now that he has these books about antique auctions, Qian Yang believes that when he has mastered them all, the previous embarrassment will never appear again.

After searching for this, Qian Yang felt that it was almost there. He also knew that there would be a lot of books hidden in other corners. For example, some collectible books with strong stories will be classified as literature, and some books with more antique art value will be classified as art, and so on.

But these are a few after all, and these books are scattered among other books, Qian Yang really doesn't have the time or the need to spend energy to find them all. He had found nearly 6,000 books before, and it would have taken him quite a long time to record them all, and he didn't even know if the time left for him by Broken Ice was enough for him to go through them all.

The sound of dripping water seemed to be a little faster than just now, Qian Yang didn't dare to slack off, and sat cross-legged in front of a bunch of books that had been marked before. The pile of books was located in a low position, and in order to prevent it from being flooded by the rising water, Qian Yang chose to start here first.

The spiritual sense landed on a book called "Introduction to Porcelain Identification" through the bookcase, and Qian Yang did not pick and choose, and read the book page by page.

When it is said to be reading, it is actually not intentional at all, it is just a simple eye. For this way, Qian Yang can be regarded as familiar with the road, and the spiritual sense enters one page after another rhythmically, and his eyes blink quickly with the immersion of the spiritual sense.

Qian Yang used his spiritual sense to record the content of the book very quickly, but the book was indeed not as refined as Yujian, and this thick book really took him a lot of time.

Qian Yang didn't bother to calculate how much time it would take to record these books, anyway, as long as the broken ice river didn't collapse, he was desperate to put all the marked 6,000 books in his head. As long as he has the backing of these books, Qian Yang believes that his achievements in the way of appraisal will not be inferior to anyone in the future, and with outstanding appraisal skills, the spirit stones will naturally flow into his pocket, and if he has a large number of spirit stones, the path of cultivation will be bright.

Qian Yang is recording mechanically, and at the same time looking forward to the future. In fact, he also knows that there is still a long way to go from obtaining the knowledge in books to having the real skills of identification. However, there is such a wonderful beginning, and the future will naturally be like a cloud, and thousands of miles can be expected.
