A lunch meal really reminded Ding Fan.

For this case, in fact, he still knows too little, and he has not completely solved even the simplest problem of rope and knots, and there are actually not many clues in the whole case.

Compared with previous cases, there are already a lot of clues in this case, but at the same time, there are not only more clues, but also many puzzles.

It's like a huge ball of yarn, which is getting bigger and bigger, and the clues that leak out of each case eventually become a mystery, and the bigger and bigger it gets, it's like a snowball.

As long as this thread is found, perhaps the whole thread group may be solved.

It's just that if you want to solve these mysteries, it's really a bit difficult at the moment, not to mention the problem of the rope, and there is no news about even the symbols outside.

Zhou Feng should have tried his best, if he found the news, he would probably have called a long time ago.

But in the morning, Ding Fan's phone never rang.

Thinking about it, I also know that eighty percent of his side is not going well.

A question of ropes, a question of symbols, and now I'm afraid to add a question of what these people experienced back then.

Because after Meng Huan's continuous investigation last night, he had already made a detailed investigation of the approximate timeline of these people, and it was really the same as Ding Fan imagined.

These people had no contact for more than 20 years, but coincidentally, they appeared in the same hospital on the same day fifteen years ago, and were in the same ward.

There are more and more commonalities, in addition to proving that there is a connection between these people themselves, but also proving that the murderer kills not as simple as random killings, but kills with purpose.

This is a serial murder case, and it is very likely that it is a serial murder case that has been planned for many years.

The cause of the murder is likely to have something to do with what they experienced together fifteen years ago, and this needs to be investigated from the hospital to make some key push.

It's just that Ding Fan didn't think about interfering too much in this matter, but handed it over to Meng Huan to deal with, and what he was thinking about now was how to figure out all the things that bothered him as soon as possible.

That strange icon, Ding Fan had already asked his uncle, but the result was a bit unsatisfactory, and the uncle had never seen such a strange symbol before.

Originally, I wanted to ask my grandfather, but this time, my grandfather told him for the first time that he couldn't do anything.

Unexpectedly, the omniscient grandfather didn't know what this thing was this time this time.

But looking back, if this thing was just a trace left by a thief, even if Grandpa didn't know it, it seemed normal!

After all, grandpa didn't have much contact with those pickpockets before, so it's not strange to know about this thing.

It seems that this time, if he wants to solve this mystery, Ding Fan still needs to think of something by himself.

At the moment, in addition to going to the library to check the information, Ding Fan has no superfluous methods, of course, even if he goes to the library, there is no guarantee that he will be able to find these useful materials, at most he will try it.

Although the library in Jin'an City is not large, the amount of books stored in it is still not small, and many famous books at home and abroad are stored, you can think of it, you can basically find it here.

In particular, you can basically find some foreign books and periodicals, and even picture albums.

I heard that many universities communicate with each other, will give each other some collections, and this library in the center of the city used to be the library of Jin'an University, and later after the relocation of Jin'an University, only this library remained, and the collection of books inside is not necessarily the original work, but there are still a lot of translated works later.

There are indeed enough books, but for Ding Fan, it is not necessarily a good thing.

Looking at the various text books placed on the more than 30 bookshelves in front of him, Ding Fan's scalp was numb for a while.

Is Ding Fan what he needs these books?

Not at all, all he needs is a book, as long as the book has what he needs, who cares about this amount?

Just these books, not to mention Ding Fan is here alone, even if there are more people, everyone in the entire police station comes, I'm afraid it's useless!

It's useless to talk too much, even if it's more, you always have to look for it, and it is impossible for that thing to jump out by itself, so you can only find it and talk about it.

Ding Fan stood in the corner of the library, taking down those obscure English books from the shelves one by one, leaning against the window and reading the content of the great ambitions on them quickly, just to find out what he needed from the inside as soon as possible.

But in the end, in addition to attracting many people to stop and watch, he didn't find anything useful.

The symbol found in front of the deceased's house before was composed of letters and mathematical symbols, which obviously would not be recorded in Chinese books, and if you want to find something more direct, it is best to look for it in these English books.

But after reading seven or eight books in a row, I almost flipped through the entire book, but there was no record of this symbol in the middle.

In order to investigate this symbol, Ding Fan almost used his speed reading skills to the extreme, and the speed of reading books was more than five times faster than that of ordinary people, but he still couldn't withstand the more than thirty huge bookshelves behind it, and roughly calculated, there were at least more than two hundred books in the back.

And the worst possibility is that after reading all the more than 200 books, he may not be able to find any traces on them, and he will have to go to the university library to take a look.

Of course, Ding Fan doesn't have to read all books, but he mainly needs to look at those books with illustrations, which may have a greater probability.

Just as he was flipping through the book with both hands, a girl stood next to him, looking at him curiously, and finally couldn't help asking, "Are you reading?"

Ding Fan ignored her, and still quickly flipped through the books in his hand, but when the book was almost finished, the afterglow of his eyes swept over her body.

Not to mention, this little girl is quite beautiful, with white and tender skin, black and beautiful long hair, floating in front of her like seaweed, under the faint eyebrows, a pair of moist big eyes flickering, like two exquisite gems, dazzling.

"Is there something wrong?" Ding Fan casually glanced at the girl's body, changed a book casually, flipped through it quickly, and said in a low voice as low as possible: "Is my voice disturbing others?"

The little girl didn't expect that Ding Fan didn't have any superfluous words to herself, but just responded to herself coldly, and looked at the book as if no one was around.

Although I can't say how rude he is, it still makes her feel a little lost in her heart, and as for where this feeling comes from, she herself is not very clear.

"No, it's just curious, you read books quite fast!"

The girl didn't know what to say, so she had to find a random reason and say it.

It's just that after saying this, Ding Fan didn't seem to hear it, and the speed of turning the book in his hand still didn't change in the slightest, which made people wonder if he was really reading a book.

Anyway, Ding Fan is not very interested in the content of the book, and what can really interest him is the illustrations in these books, which may be of some help to the case.

It's just that there aren't many such books, Ding Fan looked through the two bookshelves in a row, and the books on them were all over, and he didn't see anything useful on them.

On the contrary, it attracted the little girl beside him, and wherever he went, the little girl followed him, without saying a word, only occasionally reaching out to look at what he was looking at.

"Are you looking for the three masters of European literature and art?"

The little girl had been following Ding Fan for almost two hours, and seeing that the sun was already slightly westward, she really couldn't wait, so she asked.

Ding Fan put down the book in his hand, turned to look at the girl next to him, and asked a little puzzled: "What is the matter with you, let's be honest, you have been following me for more than an hour." ”

The girl frowned a little embarrassed, glanced at the people around her, stretched out her finger and pointed to a book in Ding Fan's hand and said, "I just want this book, you have been holding the ......"

Ding Fan looked at the book in his hand, and then he realized that this girl had been following him, and she actually wanted this book!

When I was looking through this book before, I found that there seemed to be a pattern on it that was a little similar to the symbol I saw before, but I couldn't be sure, and I thought I would take the book back and study it later.

I didn't expect that I had appropriated the books that others needed, but even if I knew it now, Ding Fan couldn't give the books to others!

"You...... If you want to use this book, can't you do anything else?" Ding Fan said a little embarrassed: "I mean, I also need to use this book, it won't take long, can you wait for me to use it up before I give it to you, or can I replace it with something else?"

The girl saw that Ding Fan was indeed useful, so she had to nod helplessly, and said a little reluctantly: "It's only like this, are you also learning to paint, or a poet?"

Draw?

Poet?

These two seem to be a little out of touch with Ding Fan!

"Don't get me wrong, I don't mean anything else, I see that what you are just reading is a collection of European poems or biographies, so ......" The girl looked at Ding Fan's face with a little embarrassment, and quickly explained: "Actually, I also learned to paint, and I also have some foreign poetry collections and books of famous painters at home, if necessary, we can exchange!"

This is a good thing, these books look obscure and difficult to understand, the most important thing is that the amount of these things is really a bit large, just rely on Ding Fan to check it here, God knows when to find it?

It's good to have someone to help, and looking at the girl in front of her, it seems to be quite simple, so she should be willing to help!

"Of course you can, I'll take a day or two to give this book, and I'll give it to you soon, in fact, I don't know much about these paintings and the like!" Ding Fan glanced at the people around him, it seemed that there were not many people in the library anymore, and it was time for the sun to get off work: "That's it, thank you for lending me the book first, I'll treat you to a meal!"

In fact, Ding Fan just said that, he didn't really want to invite her to dinner, he couldn't say that he knew her, and he didn't borrow books, and now he invited her to dinner, just to relieve the embarrassment.

Who knows, this little girl stood at the window and glanced down, turned around and nodded in agreement.

This agreement caught Ding Fan off guard, he had only been in Jin'an for two days, and he didn't know what to eat here.

Who knew that even if he said it casually, the little girl agreed, and now she can only grit her teeth and lead the little girl out to eat.
