The information that is now known is that this student borrowed more than 2,000 books from the library during his entire high school period, borrowed more than 400 books in a month after installing the computer in the school library, and borrowed more than 300 books repeatedly. Then the first time I borrowed a book was three years ago.

The administrator looked at Mo Ming seriously, wanting to know the answer.

"Do you know why?"

"Probably not."

"Classmate Mo Ming, be a little more serious, and you can always find some clues after analyzing little by little."

Mo Ming kept quiet and didn't ask anything more, where did the breakthrough in this matter begin? "A four-year high school student? Device updates for libraries? Or the contents of the borrowed books?" Mo Ming is undoubtedly caught in thinking, he has a habit, when he thinks, he likes to close his eyes, and when it is difficult to explain, he will bite his upper and lower lips slightly.

Mo Ming made this action at this time, and Qiu Yanzi also looked at him quietly on the side, silent, afraid that the current of this thought would be cut off by her sudden move.

This thinking time is unexpectedly not long, maybe I understand something, the corners of Mo Ming's mouth eased slightly, his eyes slowly opened, and Qiu Yanzi noticed this change.

"Got an idea?"

"Ah, probably."

"You're saying you figured it out? Just in this short minute? No, it probably hasn't been a minute yet."

The administrator, who had a serious expression, was now obviously a little hesitant, as if he didn't believe Mo Ming at all.

"I guess I understand the key point."

"Then tell me."

"Well...... Let's fix some other small problems first."

Mo Ming didn't answer the administrator's question directly, and bent over to look at the computer, looking focused.

"Well, can I see what books he borrowed?"

"Okay, I'll pull it out."

The slender fingers of the administrator girl jumped dexterously on the keyboard, as if playing the piano, a pleasing operation, and after a while, the books that the classmate had recently borrowed and the time of return were clearly displayed in front of Mo Ming's eyes.

Mo Ming carefully looked at these books, there are mainly two categories, one is the books that are borrowed repeatedly, and the other is the newly borrowed books and periodicals, although I don't know which books are borrowed repeatedly, but the books here can be divided into two categories, if you look carefully, it is easy to summarize.

"The ones that are borrowed repeatedly are all novels, right?"

"That's right, more than 300 of them are novels, mainly classical classics, the kind that ordinary students don't like to read."

"Can you find those books now? With your superpowers."

"Superpowers?"

"What Mo Ming said is that your ability to clearly report the location of books is a very strong memory ability, just like a superpower."

"Hehe, I lifted it, but unfortunately, I can't do it."

"Why?"

"After the library changed its equipment, a large number of books were placed in a different position, and these books may have been in one section before, but now they are all more carefully categorized."

"If that's the case, the other books should have changed places, and besides, you should be a freshman in high school, right? So you shouldn't know the distribution of books before, right? How do you know the location of "Gray Feather" and "Gone with the Wind" and the like?"

"The school magazine has always been placed in a specific position, so I know that as for the "Gone with the Wind" you are talking about, those are all popular books, and there are more people borrowing them, so they are naturally familiar with the location, but other unpopular books are basically unknown."

"So, is that the right superpower?"

"Don't talk about superpowers...... Blame the shame, and I want to ask, how do you know I'm a freshman in high school?"

"Hehe, if you weren't in high school, I might have recognized you as a junior high school, and since you're a high school student, you can only think about it at a young age." Of course, this is Mo Ming's mental activity, and he is also a person who pays attention to proportion.

"A kind of youthful vigor."

Of course, it was Qiu Xiaozi who said this kind of thing, and she often quoted the syntax of the language in the conversation, which made people smell a kind of literary youth.

"Oh, I hope it's not for any other reason."

The administrator girl glanced at Mo Ming, which made him suddenly excited, "This guy is so sharp."

"The 400 books after returning to the equipment can be divided into two categories, one is the unpopular classical novels that have been borrowed repeatedly, and the other is the supplementary books that have been borrowed again."

"Alas, there are really a lot of supplementary books, including "Introduction to Primary School English", "Junior High School Geometry", "Composition Writing Materials for Primary School Students" and so on......

"Well, I'm also a little strange, where is this book that high school students should read? But you see......

The administrator girl pointed to the computer screen and found an interesting phenomenon, there was a change in the process of the books borrowed by this person.

Mo Ming sighed a little.

"It's so inspiring."

"Mo Ming, you see, he has finally learned the grammar of the third language of junior high school, and he has also begun to learn mathematics for the second year of junior high school, which is really touching."

The administrator girl pushed her glasses with her index finger, looked off the screen, and looked at Mo Ming and Qiu Yanzi.

"I have a guess, listen to it."

"Classmates, please speak."

"Say it."

"The phases of the borrowed supplementary books are obvious, as if the progress of learning, one by one is learning rapidly, this person, the ...... It's convenient to call him student A, A is in his fourth year in our school, so he is probably a repeat student, does this mean that he is preparing for the exam?"

"Yes, and I learned from scratch."

Mo Ming nodded, and what he wanted to say was this.

"I don't know what the remaining 300 books are for, you just said that you already know the answer, it should be that the doubts about the existence of this place have been solved by you, right?"

The administrator handed over the right to speak to Mo Ming, and Qiu Yanzi also looked at Mo Ming expectantly, the reasoning before this was very reasonable, and it was natural to draw, but the next thing was absolutely difficult.

"I probably know what A wants to do, but I don't know the motive."

"So what do you think he wants to do?"

Mo Ming nodded, then picked up the thick borrowing record book, opened it to Student A's side, and pointed to his name and borrowing time.

"In the past, the borrowed book was a debit card, which was a form card sandwiched inside the book, with the time and class of borrowing and returning written on it, as well as the signature, right?"

"Yes, but at that time there were no computers in the library, and the time could only be accurate to the date."

"How do you keep track of borrowed books?"

"Students consciously fill in debit cards for borrowing and returning books, and then the librarian regularly organizes the list of debit cards in the books in the notebook."

"Is there a time when the name and class can be faked?"

"It's better not to, if the school finds out, it may report criticism."

"Is there a limit to the number of books I can borrow in a day?"

"I didn't know the rules before, but now because of the credit card borrowing, the amount of books borrowed is less than 1,000 books per month, and it is said to be 1,000 books, but no one can borrow that much, even if they borrow books from the class, it can't be so many."

"In other words, there's no limit to the number of books you can borrow, right?"

"No, I don't."

"Is it permissible to borrow fifty books a day for thirty days in a row?"

"Well, didn't Student A borrow it?"

"Fifty books are borrowed and returned on the same day, don't you feel tired? And since it is borrowed on the same day and exchanged on the same day, the possibility of borrowing books or borrowing them from the class is ruled out."

"Yes, whether it's after the library has changed equipment or before, Student A is just borrowing books for himself, right?"

Qiu Yanzi also thought about it seriously, saying this did rule out a lot of normal possibilities, and then she really didn't know the reason for the abnormality. Mo Ming looked at the two who were very puzzled, and felt that the other truths had been explained clearly, and he could talk about his abnormal thinking.

"There is no possibility of lending it to the class or lending it to anyone, and if you read it, it is very difficult to read a complete book after borrowing it for only one day, let alone reading 50 books, so we can conclude that this book is not borrowed for reading?"

The two nodded, reasonable, impossible to refute.

"Besides, it's too hard to carry fifty books in and out every day, right?"

Qiu Hina nodded.

"It's not just strenuous, it's conspicuous."

"Yes, so can we assume that the book wasn't lent out at all?"

Mo Ming's words surprised the administrator, what he meant was that the book had never been out of the library at all, was it borrowed by a ghost?

"Don't be surprised, without falsifying the name of the class at the time of the time, you can put a little thought into other things, such as falsifying the borrowing of books."

"Do you mean that Student A secretly wrote his name and other information on the debit card in the library?"

"Yes, I don't know what he wants to do, but it's a useful thing, leaving his name on the debit card."

"So is there still a use?"

"Yes, I guess, to convey some kind of message, right? Like Morse Code?"

"Mo Ming has a lot of question marks today, why are you not sure? Be confident."

Qiu Yanzi encouraged Mo Ming, because now Mo Ming's judgment is very meticulous and he can't find a loophole, maybe the answer is about to come out.

"Morse code? What information did you mean A left in the book?"

"Probably, but not all the books, I guess it's only the more than 300 books he borrowed recently."

"Huh? So what does he want to do? Collect these passwords?"

Hearing the rare and interesting things, classmate Qiu Yanzi really became excited again, and stood on tiptoe to look at Mo Ming's lazy and godless face, this lemon was almost about to devour Mo Ming, Mo Ming's face was slightly hot, and he quickly turned his head.

"Well, I don't know."

"Then let's go find these three hundred books! No, no, according to that argument, just find a few books inside, right?"

"That's right, the library computer has information about each book, so it's easy to find a few."

"Yes! That's great, let's go."

"Ah, I'm so tired, let's do it another day...... Even if you find it, you may not be able to crack it, and if you crack it, you don't know the motive, and if you guess the motive, you won't be rewarded with candy or something......

"Classmate Mo Ming, there are too many words."

Qiu Yanzi accused Mo Ming very seriously, and then suddenly thought of something, slapped his right hand with his left fist, suddenly woke up, and looked directly at the administrator girl.

"My name is Qiu Yanzi, this is classmate Mo Ming, dare to ask the girl's name?"

"I'm just talking about it now......

Mo Ming complained weakly and tiredly.

The administrator's sister was shy, and her cheeks were flushed.

"Loria."

"Loriya?"

"Don't say that, minister, she's going to cry......
