(When I got up in the morning, I found that it was sunny outside and the weather was good, so I decided to add a change for such a beautiful haodeshijie!) This is added and does not affect the update of the low level. ）――

Early the next morning, Li Yan got up early in the morning, came to the ponytail girl's bedroom in high spirits, and knocked on the door. The door of the ponytail girl hadn't opened yet, but the door of the bedroom next to her had opened first, Kang Min stuck out his head, glared at Li Yan with resentful eyes, and said faintly: "You villain, return Sister Qiao to me." ”

Li Yan spread his hands and rolled his eyes at her: "She's not your thing, I'll give you a fart." ”

"Humph!" Kang Min snorted coldly, retracted his head, and slammed the door on the ground.

Li Yanxin's hair was cold, and he secretly thought: If this thing knew that the ponytail girl was already with me, would she run away? It's dangerous.

At this time, the door of the ponytail girl opened, and today's ponytail girl has a more sweet and charming feeling than usual, and it seems that she has transformed from a girl to a woman, and her mood has also changed. In the past, her expression was more vigorous and heroic, but today it is a little more feminine. When she saw that the person outside the door was Li Yan, two red glows suddenly flew on her face, and she remembered the wonderful feeling of yesterday, and couldn't help but feel a fever in her heart: "Classmate Li Yan, are you coming to me?" What's the matter? ”

Li Yan took out three senior library cards and said with a smile: "This is what we earned by singing, let's go borrow books together." ”

The ponytail girl said happily: "Okay." ”

The two walked out of Meizhuang side by side, the morning air was exceptionally fresh, the birds were singing, and there was harmony and tranquility on the black wood cliff. In fact, today's Blackwood Cliff is not much different from the usual Blackwood Cliff. But the two are "newlyweds". The mood is very different from yesterday. The shijie they saw in their eyes was a little more vibrant than usual.

Li Yan said: "Half a month later, I want to take a long vacation, and I may have to leave school for a while. ”

The ponytail girl asked, "Want to leave school to do a mission?" ”

Li Yan didn't hide it from her, and replied: "Well, Wei Xiaobao's task over there is a bit difficult, and I want to help her." Originally, she was not supposed to be in danger, but because of my mixing. Her situation has changed, and if I don't care, something will happen to her. ”

The ponytail girl then thought that the braided girl came in last night and disturbed her and Li Yan's good deeds, it turned out that she had a task, she was not a girl who held a grudge, since this was the case, she forgave Wei Xiaobao for the interruption, and said a little worriedly: "Is it dangerous?" Why don't I go with me? ”

Li Yan thought about the strength of those enemies in "The Legend of the Deer and Ding", then shook his head with a smile and said, "It's not a difficult task. The enemies are weak, so don't worry. ”

The ponytail girl is actually a little afraid to see the braided girl. The embarrassment of last night has not been erased, although she has not been recognized, but as long as she sees the face of the braided girl, she may die of shame on the ground, so she does not force it.

The two of them said some plain conversations, but the feeling of happiness came spontaneously, and before they knew it, they walked to the front of the Scripture Pavilion. In the past, every time Li Yan came, he could see Wang Yuyan sweeping the floor here, but he didn't expect to come over this time, but he saw that there was no one in front of the Scripture Pavilion, and Wang Yuyan was not there.

Li Yan couldn't help but wonder: "It's strange, the librarian is not here, isn't the school afraid that someone will steal the book?" ”

The ponytail girl smiled: "Who dares to steal?" If you make the Oriental girl angry, please invite the four famous people to arrest and investigate, who can stand it? ”

Li Yan thought about it, this is also true, stealing things will always leave some clues, ordinary people may not be able to find out, but once the four famous catchers are dispatched, cough ...... Oh my God, there are also four famous catchers in this plane? Li Yan's sweat flowed out in a hurry, and he thought: Ruthless must be a girl in a wheelchair with a broken leg, all of her body is a hidden weapon, and she will not tolerate the killer of the enemy. Iron Hand should be a gentle girl with a pair of unstoppable hands. The chasing is a drunkard girl with a pair of slender legs. Cold-blooded should be a cold-hearted and arrogant girl who walks alone with a sword, it must be so. The four of them are fast and thoughtful, so they must be able to grasp the key points, right?

While thinking wildly, the two walked into the Scripture Pavilion.

Wang Yuyan is really not there, there is quiet in the Scripture Pavilion, only a woman is standing in front of the bookshelf of intermediate cheats reading, this woman's age seems to be not young, her hair is gray, her back is facing Li Yan, and she can't see her face, but Li Yan feels that she is a little familiar, it seems that she has seen it somewhere, but she can't remember it for a while.

Li Yan's library card is advanced, and he wanted to go to the bookshelf of high-level cheats, so he passed by the bookshelf of intermediate cheats and walked inside. At this moment, the gray-haired woman raised her head, saw Li Yan, and couldn't help but say "Huh", "You are Li Yan, you are Qiao Feng, and the two of you are the first place in the singing competition." ”

Li Yan looked back when he heard the sound, and recognized it this time, this woman was actually Aunt Ying. She looked similar to that day on the martial arts stage of the singing competition, and her dress did not change much, a mature woman in her thirties, her body was very hot, and she was so mature that she was about to drip water, and the only drawback was her gray hair, which made her look dozens of years older out of thin air.

Aunt Ying was holding a copy of "Nine Chapters of Arithmetic" in her hand, and it seemed that she was flipping through the book just now, and happened to see Li Yan and the ponytail girl, so she said hello.

Li Yan saw that it was Aunt Ying who greeted him, and his heart was also full of strangeness, and said, "That's right, I'm Li Yan, this is Qiao Feng, you are Aunt Ying's sister, right?" I don't know what to tell us? ”

Aunt Ying said: "That's right, I'm Aunt Ying, I'm looking for you, I want to discuss with you......"

Li Yanqi said: "What are you discussing?" ”

Aunt Ying said seriously: "You won the first place, and you got three senior library cards, one for each person, and one more, can the third one be used to help me borrow a book?" I won't lend your card in vain, you can try to make conditions, as long as I can do it, I will agree to you. ”

Li Yan shook his head and said, "This ...... I'm sorry, I don't think I can exchange my library card, it's more valuable than anything. ”

Aunt Ying was immediately anxious: "You use this library card, don't you just want to borrow advanced martial arts cheats?" As long as you are willing to use a high-level library card to help me borrow books, I will teach you this advanced martial arts, so that you are equivalent to borrowing a secret book? ”

Her proposal is not bad, Li Yan was immediately moved, in the book "The Legend of the Condor Heroes", she specially introduced Yinggu's loach skills, which is a very clever kung fu that can make the enemy's palm force hit the body and be slid to the side. In the condor shooting, Guo Jing used the eighteen palms of the dragon to slap on Yinggu's body several times, but they were all dissolved by the loach skill, which shows the power of the loach skill.

Li Yan thought to himself: The martial arts borrowed with a high-level library card may not be better than the loach skills, if such an exchange is made, it is reasonable and not a loss. I went to King Jin's Mansion this time and was injured by Ouyang Ke's fist, and if I knew how to do loach skills at that time, I wouldn't be afraid of her at all.

Li Yan hurriedly said: "Okay, deal!" You teach me loach skills, and I'll help you borrow a high-level cheatbook. ”

The two hit it off, Aunt Ying was overjoyed, and hurriedly took Li and Qiao to the bookshelf of the high-level cheats, and hurriedly said: "What I want to borrow is this book, look, it's here, it's called "The Picture of Luoshu". She looked eagerly at a hardcover book on the shelf. It can be seen that although she wants this book very much, she doesn't dare to reach out to take it, she only dares to stare at it, it seems that the rules of Heimu Cliff are really strict, she doesn't have a high-level library card in her hand, and she doesn't even have the qualifications to touch the high-level cheats, so she can only look at the treasure book with red eyes.

Li Yan didn't have this concern, he reached out and took down the "Picture of Luoshu", flipped through it casually, and said with a smile: "I'll take a look, what's the treasure of this book, it actually makes you want it so much." ”

After only a few glances, Li Yan smiled dumbly, this book is not a martial arts cheats at all, but an arithmetic book. The book is painted with a diagram of the nine palaces, and there are many methods of mathematics written next to it, Li Yan read casually: "The outer four circles are distributed in four directions, which are square, and the ten packs of five are included, and the circle is still hidden in the circle, and the circle is hidden in the square, and there is yang in the yin, and there is yin in the yang...... Is this geometry? ”

This is an ancient arithmetic book, of course the algorithm in it is not very clever, Li Yan read a few paragraphs, then laughed dumbly, thinking: This is the level of junior high school and high school mathematics in later generations, and it was actually put on the bookshelf of advanced martial arts cheats, and it was laughing to death.

Hearing Li Yan read a paragraph casually, Aunt Ying's face showed a fanatical expression, and she said stupidly: "Yes, this is it...... The most advanced arithmetic book, if you learn this, you can learn the clever formation...... Quick, give it to me. ”

Li Yan smiled dumbly: "Sister Ying, what kind of treasure book do I want to borrow, forget about this level of arithmetic book, it's too wasteful of library cards, I can teach you arithmetic casually, and it is a hundred times stronger than this book." ”

Ying Gu was immediately furious: "What did the kid say? This book is the work of a master of mathematics, recording the most powerful changes, you are young, you can't read this book, you dare to boast of Haikou? ”

Li Yan smiled: "Okay, if you look down on me, I'll just test you with a random question to see if you can do it." ”

Ying Gu sneered: "My nickname is God Operator, if you can't do the questions of your little brother, you don't have to mess around." ”

Li Yan said: "Now there is an army that needs to pay food, the first soldier needs to be given three buckets of rice, the second soldier needs to be issued six buckets of rice, the third soldier needs to be issued nine buckets of rice, the fourth soldier needs twelve buckets of rice, and so on, how many buckets of rice do the one hundred and eighty soldiers need?" ”

When Aunt Ying heard this question, one head was suddenly bigger than two. She hurriedly took out the calculation chips she carried with her and calculated: "Each soldier has three more buckets, the fifth soldier is fifteen buckets, the sixth soldier is eighteen buckets, and the seventh twenty-one buckets...... The eighth twenty-four bucket ......" She counted them one by one, and after a while, her hair turned gray again, and sweat flowed down her face.

It took a long time for her to count fifty soldiers, and she was already sweating. (To be continued......)
