A few regulars who spent the day in the library were familiar with the layout and structure of the library, and after a while they were back on the fifth floor, holding the same book with a different cover - the third book of The Hitchhiker's Guide to the Galaxy, "Life, the Universe and Everything" written by Douglas Adams, which was available in Chinese, English, and other languages, and published in different years.

Zhang Zi'an has also read this classic science fiction, but he never knew that there are so many versions of this book......

They found a spare table and lined up the books all over the table, and it looked spectacular.

Some of the other readers didn't know what they were doing and looked inquiringly.

They returned to their seats and began typing in English.

[Coco]: We've found the book you want, so we'll put it on the table on the fifth floor and go up the stairs, and we'll pick it up.

All those in the know, including Zhang Zi'an, looked at the table covered with books, waiting for what would happen. Especially Zhang Zi'an, although he thinks that the answer will not be so simple, he is also quite worried that if one of the books suddenly disappears in front of everyone's eyes, it will become a supernatural event and cause a sensation......

As the minutes ticked by, the air in the library was almost suffocating, and the entire fifth floor was all seated in place, not a single person stood up, and of course there were no supernatural events such as books disappearing into thin air.

[3.1415926]: This is not my book.

After struggling to make out this sentence in English mixed with a string of pi, several of the regulars Coco knew were a little tightened in their chests, thinking that they might have been tricked and almost vomited blood! If they found the wrong one, it didn't matter, they could look for it again, but they obviously found the right one, but the other party didn't admit it...... Isn't this blatant deception?

[Coco]: But isn't that the book you're looking for? Life, the Universe, and Everything, or which specific edition do you want? I've heard that some people are very picky about publishers......

[3.1415926]: My book has no name.

[Dashuaibi]: Your book doesn't have a name, it's about life, the universe, and everything?

[3.1415926]: Yes, can you find my book?

[Jackdaw]: I'm sorry, we don't help, so you'll have to find it yourself!

[Pancake Fruit]: Yes, there must be a limit to playing tricks, wantonly consuming other people's kindness, and it will make people feel chilled if you do this.

[Coco]: Don't be discouraged, let's try again!

[Jacaranda]: HMMMMM, I'm not familiar with sci-fi, but I want to move a small bench and continue to watch the excitement.

Some of them spoke in Chinese, others in English, and their words were full of indignation and banter. Zhang Zi'an waited for their verbal and written criticism to come to an end, and continued to type.

[Dashuaibi]: I forgot to ask, you said that you were looking for your book, can I understand that this book is not a book provided by the library, but you brought it yourself?

[3.1415926]: Yes, it's the book that appeared in this world with me.

[Dashuaibi]: Last question, this book is about life, the universe, and everything, does that mean the content of the book is very complex?

[3.1415926]: Yes, can you find my book?

Zhang Zi'an understood that this book and this elf are probably in a symbiotic state and interdependent, and this elf currently exists incompletely in this world, so it has no body, and it must get this book to become a complete body.

At the same time, he understands why it is so difficult to capture - his task is to find an all-encompassing book with no name, no register, and no name from the library's collection of more than two million books!

Finding a needle in a haystack is all that way, right?

And this Nima is still a limited-time mission!

Pit daddy!

The conversation between Zhang Zi'an and the elf seemed completely inexplicable to others, and it was not logical to bring bags or books in the library.

The elves are really asking for help, asking others for help in order to survive.

Zhang Zi'an re-entered the game's electronic map interface and looked at it, and the light cluster representing the elf's location was already very dim, and it could dissipate at any time like a mist before the morning sun rose.

[Dashuaibi]: I don't know if I can find it, but I'll try my best.

[3.1415926]: Thank you.

Zhang Zi'an pushed away the chair and stood up, Coco walked quickly with light steps, and asked in a low voice, "Do you really want such an inexplicable book?"

"I have to find it. Zhang Zi'an replied.

He didn't have time to explain, and it was a waste of time to cover up, so he waved his hand and went downstairs, leaving Coco alone in the wind, while the other readers chatted in the chat, waiting to see how the farce would end.

Zhang Zi'an came to the fourth floor and slowed down at the staircase.

Although he let out bold words, he didn't know how to find them.

I don't know the size, thickness, binding, style, content, and classification of the book, so how can I find it?

However, he had a guess - the book appeared in this world with the elves, that is, it was a book summoned from the void by the Pet Hunter game. Like the elves to be captured, the book is not visible to the average person, but it can be seen through the game's capture interface!

The situation on the fourth floor is slightly better, because the shelves are full of literature and newspapers, and if there is a book on a certain shelf, it is still quite easy to see.

He searched the fourth floor, but he couldn't find it, there were no books on any of the shelves, and if he could find it on the fourth floor, the task would not be extremely difficult.

Zhang Zi'an went down to the third floor, and from now on it was like entering hell mode.

He looked helplessly at the shelves lined up in the foreign language reading area on the third floor, which meant that he had to carefully filter each shelf, because the book might appear on any of the shelves. Each shelf has six floors, and the book can appear on any of them. There are dozens or hundreds of books lined up on each shelf, and the book may be tucked between any two books.

To find this book, he had to hold his phone up to an area of the bookshelf, look through the game capture interface, then look at it with the naked eye, and then compare the two to find the extra book that is not visible to the naked eye but can be seen through the game capture interface - how difficult is it to find it from the collection of more than two million books, and find a specific stone from the mountain of books.

Even if there is a road to the book mountain, it will take time to reach the top!

What Zhang Zi'an lacks most now is time!

If it is too close to the bookshelf, the range that the mobile phone camera can shoot at a time is limited, and it is easy to see too far away from the bookshelf...... He tried a few times and found that it was best to stand at a moderate distance, with the first to sixth floors of the bookshelf filling exactly the entire space in the portrait orientation of the phone screen, and then scanning it layer by layer with his eye.

The horizontal length of the bookshelf is very long, and on average, Zhang Zi'an has to compare each bookshelf more than a dozen times - the bookshelf is two-sided, the sum of the number of times the front and the back are two.

To avoid slipping through the cracks, each comparison takes at least twenty seconds, with the focus of the eyeball switching back and forth between a close-up phone screen and a slightly farther bookshelf......

The densely packed books on the shelves are dazzling in colors, green, yellow, black, white, red...... It's all mixed together, like a big dye vat, especially since these books are still foreign titles, and those twisted flowery characters on the spine are easy to get sick after looking at them for a long time.

After reading the front of each bookshelf and then going around to see the back, it didn't take long for Zhang Zi'an to be dizzy, with bursts of nausea and nausea, even so he gritted his teeth and insisted.

However, seeing the hundreds of bookshelves left on the third floor, and the only number of bookshelves on the second floor, he knew that unless he was lucky, he would never have time to find the book before the elf disappeared.

Holding the mobile phone in the same posture and the same height for a long time, his arm was already sore, this is still after he and Lao Cha practiced a pair of unicorn arms, if he was replaced by his previous weak body, it would not take a few minutes for the arm muscles to spasm.

When he came down from the fifth floor, he also took the book "Modern Genetics: Anatomy from Genes to Surface" with him, and kept it under his armpit, pretending that ordinary readers were looking for a book, but now his arms were sore and tired, and the book had become a burden, and this forced pretending was meaningless.

So he looked at the open space on the bookshelf and was about to stuff the book back.

"Store Manager Zhang, are you still looking for books?"

Zhang Zi'an maintained the same posture of putting the book down, and turned his head to see that Meng Li was also standing next to him with two books, looking leisurely and wandering, and the woolen coat he had taken off before had been put back on his body.

Meng Li noticed the English version of the modern genetics monograph in Zhang Zi'an's hand, and was deeply surprised in his heart, and some of the remaining doubts completely dissipated, thinking that he was really concentrating on the study of modern genetics.

"Store Manager Zhang, have you read all such a thick English monograph?" Meng Li asked politely.

Zhang Zi'an subconsciously pretended to be forced: "...... After a cursory flip through, the content of this book is a bit shallow, and it can't satisfy my appetite, so I want to find something deep. ”

Meng Li smiled: "No matter how deep I am, I'm afraid I can only study the latest papers." ”

Zhang Zi'an didn't want to dwell on this issue, so he changed the topic and said, "Teacher Meng, you are also looking for books?"

"I've finished looking for both books on arithmetic superfiltration, mainly studying the solution of infinite element Diophantine equations. Meng Li raised the two books in his hand.

Zhang Zijia smiled as if he could understand.

Meng Li looked at the sky: "It's almost noon, I'm going back to school." Manager Zhang, are you going to stay here for a while?"

Zhang Zi'an nodded: "Stay a little longer, I haven't found the book I'm looking for." ”

"Oh, it's also about modern genetics?" asked Meng Li politely and casually.

"Uh...... It's about life, the universe, and everything. Zhang Zi'an said with a wry smile, mentally prepared to be ridiculed.

However, Meng Li did not laugh at him, but was slightly surprised, revealing a rather surprised look, and asked, "Store Manager Zhang's hobbies are really extensive...... Do you like to study mathematics in addition to modern genetics?"
