After entering the door, Gu Mengmeng breathed a sigh of relief quietly, and was just about to turn around and walk to the edge of Shi Hua when he was stopped by the Ji Qì people. The situation suddenly became tense, and Abu was nervous about to rush over but was glared at by Gu Mengmeng vaguely, and immediately stood up, pretending to stop a student at the back. Gu Mengmeng's heart was beating fast at this time, and he was constantly thinking about what countermeasures he would have if he was discovered.

The electronic eyes of the machine qì flickered, "Please sign!" As the unique metal sound quality of the machine sounded, what appeared in front of Gu Mengmeng's eyes was a capacitive screen board, one end of which was tied with a stretchable spring with an electronic pen. Gu Mengmeng lowered her eyes, quickly filled out the form and signed her name. Then he turned around and left, this time Gu Mengmeng was not stopped.

After entering the security gate and bypassing the screen, Gu Mengmeng saw the whole picture of the library. Three or four meters away from the screen are several small tables and small cushions half a meter high, presumably for children to rest. Behind this large row of small tables and small cushions are neatly arranged bookshelves. These bookshelves are not very high, probably to make it easier for children to access, and the height of the bookshelves is set at about one meter five. The space on the bookshelf is not wasted, and a few grids are set up, and all kinds of small things are placed on each grid, probably for aesthetics?

Gu Mengmeng and Abu looked at each other and then went their separate ways. Gu Mengmeng asked Shi Hua if he needed to take a break, Shi Hua said that he was not tired, and then Gu Mengmeng and he slowly entered the bookshelf to check. It's very strange to say, Gu Mengmeng has seen the high-definition uncensored big picture printed out by Wei Qi for him, and the pattern composed of the numbers in the trophy is either a fish or a fruit or something, and there is only one number that is a key. This has to be noted, but what does this graphic representing a number represent?

Gu Mengmeng carefully browsed the books on the shelves while thinking.

"Mengmeng! With so many books, how do I read them? I don't even know what to choose! Shi Hua looked at the neat and neat physical book with a new curiosity, and asked in a low voice while pulling the corner of Gu Mengmeng's clothes, he remembered that on the way here, Gu Mengmeng told everyone that you should not make loud noises in the library, you should not run around, you should do your own thing quietly, and if you have any questions, you can ask the teacher in a whisper.

Gu Mengmeng's gaze moved from the rows of books to Shi Hua, who was pulling the corners of his clothes, "Then what kind of books do you want to read?" Gu Mengmeng smiled and pulled Shi Hua, who was pulling the corners of his clothes, to the side of the bookshelf, bent down and pointed to the display screen in the half-point position of the bookshelf, "Have you seen this?" This display screen shows the classification and introduction of all the books on this shelf, for example, the display screen on this bookshelf shows the word garlic plant, with illustrations and text descriptions and pattern picture books. See this? There's a button to enter, if you're looking for some books you're interested in but don't know where to start, just enter a keyword here and the system will automatically find you the coordinates of the book you're looking for! For example, the letter J on this display is the number of rows, and N is the number of columns. Got it? ”

"Hmmm! Got it! Meng Meng is counted according to the alphabet arrangement, right? ”

"Hmm!" Gu Mengmeng touched Shi Hua's head and whispered, "Go ahead!" ”

"Hmm!" Shi Hua nodded firmly, turned around and stared at the display screen seriously, writing one stroke at a time.

watched Shi Hua seriously enter the word 'peach', and then the little chrysanthemum ~ flower on the display screen turned around and gave the answer in an instant - H row S column! Gu Mengmeng's smile that was still hanging on the corner of her mouth instantly froze, and in the flash of light, Gu Mengmeng had an incredible guess in her mind - could those patterns made of numbers be related to the arrangement on this bookshelf? But these shelves can be counted from four directions! So is the pattern of these numbers the key point in determining these bookshelves? Even if you find a bookshelf, what if you find it? Could it be that there is any mystery hidden in these bookshelves?

At this moment, Gu Mengmeng's mind was full of all kinds of speculations, but there was no half point on his face, and even that stiff smile was twisted by Gu Mengmeng into the surprise of seeing Shi Hua use the display screen so quickly. Later, after Shi Hua said goodbye to Gu Mengmeng, Gu Mengmeng pretended to be attracted by the books in this library, and then walked around. Taking advantage of this opportunity, Gu Mengmeng quickly recited a set of numbers jù in the drawings given by Wei Qi - 16, 9, 7, 2, 2, 3, 8

Gu Mengmeng quickly converted in her heart, and the letters she finally came up with were: P, I, G, B, B, C, H, but what do so many letters mean? Could it be that the last few are ISBNs? Gu Mengmeng pretended not to care~ took out a book, flipped through it casually, and finally glanced at the lower corner of the book inadvertently, and Gu Mengmeng was so angry that she almost vomited blood! Nima, even the layout of the library and the order of the bookshelves are in accordance with the 21st century, why can't you number the books according to the ancient times? What the hell is this 2D scan code! The I've taken off my pants, are you going to show me this?

If it weren't for Gu Mengmeng's cultivation, she would really be able to drop the book in her hand at this time! You said that this is about to verify whether this final 'password' is as you think, and the result is stuck in this position at a critical moment, and everyone is going to vomit blood.

Gu Mengmeng, who took a few deep breaths, pressed her anxiety, stuffed back the books in her hand, rolled her eyes, stopped directly in front of a bookshelf, and searched for the word 'recipe', but Xiaoju ~ Hua turned around several times, and just when Gu Mengmeng was about to give up, a few letters suddenly popped out. Gu Mengmeng hooked the corners of her mouth proudly, hum, now the next course is available, and I just need to go outside to find resources, even if the old dean sees something, he will definitely not be able to catch me here! It's a win-win-win!

Gu Mengmeng looked at the letters on the shelf, and after calculating how far the book she was looking for was from this bookshelf, she walked slowly to the bookshelf, her fingers crossed the rows of 'recipes', and finally took out a book that looked quite fancy, flipped through it casually, and found that it was a snack, and it seemed to be a snack with a long history, Gu Mengmeng decisively opened her personal terminal, aimed at the two-dimensional scan code under the book, which looked small and small, and scanned it. The book's identification code was scanned: KJHM-1110813

And so it was! Gu Mengmeng thought that when she saw the graphics composed of the numbers sent by Wei Qi, she felt that some numbers seemed to be connected, for example, the letter KJHM that represents the book identification code is converted into numbers, which is 1110813, so as long as the order of the bookshelves here is recorded, and then the species categories represented on the bookshelf are recorded, but this is really a huge number! Even if this ordinary person comes in, he can think of so many things, and it is difficult to crack this 'password'! No wonder the old dean is so fearless! It's a pity that the person he met was Gu Mengmeng, and this changed to someone else, maybe he knew what was wrong here, but he just couldn't find what the problem was. Therefore, compared to Gu Mengmeng's bad luck, the old dean is unlucky!

In the 21st century, Gu Meng often takes care of a class of children in a secondary school, not only to remember the name of the child, sometimes the child is sick, this illness is a big ~ wave, parents often tell him to remember to give medicine to their children on time when they give Gu Meng. At first, Gu Mengmeng would hold a small bag of medicine and then write XXX on a post-it note, eat it when she was full, eat it before eating, etc., and paste it on the bag of medicine, often before she remembered it, and a few more adults came to hand over the medicine, so Gu Mengmeng was often in a hurry at the beginning. Later, as I gradually became proficient, I began to be able to use it with ease. Gu Mengmeng can not only remember the child's name, but also recognize the child's parents, and also know how to remember people's names or things effectively and quickly. Even when the child was sick, when the parents handed over the medicine, Gu Mengmeng would not be so at a loss. Therefore, it is really not very difficult for Gu Mengmeng to remember some useful books and numbers in this library.

Gu Mengmeng took advantage of this time to carefully wander around these bookshelves, trying not to use the display screen on the bookshelf to find books, because this would leave a search record, and Gu Mengmeng was worried that something would be exposed.

An hour later, Gu Mengmeng wiped the sweat on her forehead, pretended to be very tired, and then pulled out a copy of the painting atlas at the bottom level, sat on the small cushion and drew with the children on the side. Abu came back smiling, unable to sit down because of the threads on Abu's feet, so he had to bend down to instruct a few children to draw, or whisper to them about some small problems they didn't understand.

In this way, until the closing time of the library, Gu Mengmeng and Abu led these children who were reluctant to give up the library back. When returning the book, Gu Mengmeng also reminded the child that he could scan the two-dimensional scanning code under the book, and then enter the number of the book in the bookshelf to download and scan the book into his personal terminal! After the children have downloaded their favorite books, they will go back happily. In their cognition, they thought that they could only enter the library once in their lives! That's why they are so reluctant to leave, but with downloaded books, it's different, which means that they have really been to the library! When these children grow up, they will remember the first time they entered the library when they encounter setbacks and difficulties, and then they will be convinced that nothing is impossible! This belief has made a huge difference in their lives for the rest of their lives! Of course, this is a later story, so I won't mention it for the time being.

After saying that Gu Mengmeng and Abu came out of the library, Abu began to chatter, thinking non-stop, and finally Gu Mengmeng couldn't stand it anymore, "Okay Abu, can you not keep thinking about it?" I was going to compliment you on a good job, but you started to coax you? Stand up straight, with your back straight and your mouth closed! Haven't you heard that the partition wall has ears? I don't think it's home yet--well! ”

"Moe, Moe, you, don't talk nonsense! You—your hands are black! Now it's all upgraded to indiscriminate attacks! Shall I go home soon? Hahahaha~ I'm just nervous, nervous! As soon as Abu saw that Gu Mengmeng was going to spit out some nonsense, he hurriedly stepped forward and covered Gu Mengmeng's mouth, at this time, he couldn't fall short!
