Genius Girlfriend

Chapter 17: FPGA electronic board

At 7:40 the next morning, Jiang Yubai brought the review book and stepped into the office of the teacher Wu.

Just in time, Wei Rongjie and Liu Xingjian also came.

Jiang Yubai, Wei Rongjie, and Liu Xingjian stood in a row and stood in front of the head teacher honestly.

Teacher Wu accepted the review book from the three of them and read it on the spot. Her eyebrows wrinkled and tightened, and her facial expression became solemn.

Jiang Yubai was a little nervous. Last night, he personally copied the review. He kept Lin Zhixia's manuscript at home, and then gave his copy to Teacher Wu.

There is no doubt that Lin Zhixia's writing style is obvious. Her vocabulary is very rich, and her ability to choose words and make sentences is extraordinary.

In contrast, Jiang Yubai's language level still has a lot of room for improvement. Jiang Yubai suspected that Teacher Wu would find that the review book was actually written by Lin Zhixia.

Teacher Wu has been teaching for many years and has a pair of insights.

She is the head teacher of the key class of the Provincial Experimental Primary School. She has taken many students, and she must be very aware of the tricks of elementary school students.

Jiang Yubai began to think, if Teacher Wu sees through the truth, how can he justify so that Lin Zhixia will not be involved.

He hadn't figured out why, so Teacher Wu suddenly said, "Liu Xingjian, Wei Rongjie, you two, did you seriously write a review yesterday? The 800-word review is the same thing over and over again. What do you two mean? The attitude is very bad."

Liu Xingjian's face was pale, and he stopped talking.

Wei Rongjie vaguely said: "Teacher Wu...I, I can't write..."

He sniffed and sniffed quietly.

Jiang Yubai sympathized with Wei Rongjie.

Yesterday morning, Jiang Yubai also struggled and struggled to produce 13 words.

Without the help of Lin Zhixia, Jiang Yubai would not be able to produce an 800-word self-examination after staying up all night.

why?

It may be because Jiang Yubai did not subconsciously think that he had committed a terrible mistake. It is not an unforgivable thing that he draws comics and plays games with the whole class. Lin Zhixia also let the class see the wonders of the world, the beauty of physics, the mysterious charm of astronomy, and the importance of economic models.

Jiang Yubai nodded. Yes, his review is only forced by the situation. He still has a thirst for knowledge in "Exploring the Universe".

"Jiang Yubai," Teacher Wu praised him at this time, "Your review book is well written. Teacher Wu can feel that you really regret it, know your mistake, and correct your attitude."

Teacher Wu handed Jiang Yubai’s review book to Liu Xingjian’s hands: "You have to learn from Jiang Yubai’s good qualities of correcting mistakes. I will criticize you for your good. I don’t care about you, that’s what Hurt you. Liu Xingjian, Wei Rongjie, before 8 o’clock tomorrow morning, give me an 800-word review. Correct your attitude, okay? Don’t let me see repeated sentences, don’t write a sentence over and over again Ten times. That was perfunctory teacher, and you did not correctly recognize your shortcomings."

Liu Xingjian and Wei Rongjie can only obediently respond.

After walking out of the office, Wei Rongjie hurriedly followed Jiang Yubai and asked, "Jiang Yubai, why is your review written so well? You didn't pull other classmates into the water, and you didn't talk bad about others..."

Jiang Yubai replied: "The review book is a review of myself, I will not involve others."

"Jiang Yubai," Liu Xingjian suddenly called to him, "You stop me!"

Jiang Yubai rushed into the classroom. His sports coat was slightly open, and it was as elegant as a knight when running. He threw a word to Liu Xingjian: "Why should I listen to you?"

Liu Xingjian was irritated by him again.

Originally, Liu Xingjian wanted to honour his dignity, so he personally asked how to write a good review-this was the only opportunity Jiang Yubai could please Liu Xingjian.

If Jiang Yubai counseled patiently and behaved polite enough, Liu Xingjian would forgive Jiang Yubai and forgive Jiang Yubai for all the mistakes he made before.

However, it is a pity that Jiang Yubai wasted this precious opportunity.

Liu Xingjian punched the front door of the class and said gloomily: "Jiang Yubai! You wait for me!"

As soon as these words came out, the whole class couldn't help but look at Jiang Yubai.

Jiang Yubai completely ignored Liu Xingjian. He couldn't wait to return to his seat and reported to Lin Zhixia: "Mr. Wu accepted the review. She didn't let me rewrite it."

Lin Zhixia was not surprised: "Great."

Jiang Yubai opened his schoolbag and found a copy of "Fourth Grade First Book Math" that he would use in the next class.

He pretended that he was reading the contents of a math book. He brewed for a while, maintaining a proper posture, and said sincerely and formally: "Lin Zhixia, thank you for your help."

"What did you say?" Lin Zhixia put a hand to her ear, "I didn't hear it."

Jiang Yubai sneered: "Just forget it if you don't hear it."

Lin Zhixia sneered like him: "Hahahaha, Jiang Yubai, are you shy?"

Jiang Yubai was not shy at first, but he felt a little embarrassed when asked by Lin Zhixia. He changed his sitting position, facing the other direction, further away from Lin Zhixia.

Lin Zhixia called him: "Jiang Jiang Jiang Jiang over white!"

Jiang Yubai responded immediately: "Lin Lin Lin Lin Lin Zhi Xia!"

Lin Zhixia said "Hey": "I thought you would say, crazy."

Jiang Yubai insisted: "These three words are a bit offensive. If you want me to say it, I don't know how to say it."

The two of them were bickering, and suddenly the dean's voice came from the school radio.

The instructor asked the fourth-grade class leader and deputy class leader to immediately go to the printing room to receive an important material. The class teachers of each class must also coordinate their recent work.

The dean announced via radio: "Upholding the principle of voluntariness, classmates in each class, you have to inform your parents to choose whether to vaccinate hepatitis B vaccine."

Hepatitis B vaccine!

Lin Zhixia's face paled when she heard these four words.

She is most afraid of injections!

When she saw a needle, she felt fear. What universal truth, what Nietzsche's hypothesis, what kind of second-type string theory, will all be left behind by her. That sharp and sharp needle is the whole world she sees in her eyes—of course, that world is horrible and dull.

Where is Jiang Yubai?

Is Jiang Yubai afraid of injections?

Lin Zhixia suddenly turned her head and stared at Jiang Yubai without saying a word.

Jiang Yubai was so stared at her that his heart grew furry, and couldn't help asking: "What's wrong with you?"

Lin Zhixia's eyelashes blinked twice. How can she tell Jiang Yubai how much she hates injections?

In the "Exploring the Universe" series of comics, Jiang Yubai portrays Lin Zhixia as "the **** of truth, the first military division, and the space navigator." These extraordinary titles brought a trace of idol baggage to Lin Zhixia. She was ashamed to admit that she would cry when she saw a needle.

As a space navigator, the first military division of the earth, and the **** of truth in the Orion base, Lin Zhixia is not strong at all. A mere hepatitis B vaccine can make her feel dangerous.

However, if Jiang Yubai is also afraid of injections, Lin Zhixia can gain his empathy. Lin Zhixia asked roundly: "Jiang Yubai, did you hear the broadcast just now?"

Jiang Yubai said calmly: "I heard it."

"Do you have any thoughts?" Lin Zhixia cautiously tested him.

"I have no thoughts." Jiang Yubai pulled out the cap of his pen and wrote a math homework assigned by his tutor. "I was vaccinated against hepatitis B last year."

So, this time, does Jiang Yubai no longer have to vaccinate?

Lin Zhixia envied him.

She asked bluntly: "Do you cry when you get an injection?"

"Why are you crying?" Jiang Yubai was puzzled, "It's over for a while."

Lin Zhixia's problem ends here. She has determined that Jiang Yubai doesn't care about "injection" at all. She was like a down-and-out soldier who had lost her allies, and she had been living in a muddle all day.

But she still has a glimmer of hope-the hepatitis B vaccine is not free. Not only is it not free, but it is also expensive.

The squad leader and deputy squad leader went to the printing room and received the hepatitis B vaccine brochure. This batch of brochures was distributed to every student by the monitor. In the brochure, it is clearly written in black and white: Our school cooperates with provincial tertiary hospitals to ensure the safety, reliability, effectiveness and stability of the hepatitis B vaccine. Hepatitis B vaccine is 72 yuan per person and 24 yuan per dose...

After reading this, Lin Zhixia's mind flashed.

Yes, she knows that hepatitis B vaccine must be given at least three times.

24 yuan per time, 72 yuan three times.

Indeed, 3 times 24 equals 72.

However, my mother was very reluctant to pay 76 yuan for the autumn trip last time.

This time the 72 yuan hepatitis B vaccine, my mother must not accept it!

Lin Zhixia won't have to get an injection if his mother doesn't give money!

That evening, the setting sun shone across the earth, and the cold wind in late autumn mixed with coolness.

Lin Zhixia broke into the house with her schoolbag on her back and handed the Hepatitis B Vaccine Brochure to her mother with confidence.

She behaved very well, very quiet, just waiting for her mother to say: Xia Xia, there is no money at home. Can this 72-yuan vaccine not be used?

She can answer happily: Okay, mother. Xia Xia didn't want to get an injection.

However, things backfired.

My mother carefully read the "Hepatitis B Vaccine Brochure" and called Lin Zhixia's father loudly.

Father and mother discussed for a while, and father suggested: "Xia Xia had been vaccinated against hepatitis B when she was born. She is 9 years old now, and the brochure says that the antibody titer will decrease year by year, or let's ask her to get another shot. vaccine?"

Mother readily agreed: "Okay, let her go to school. The doctors in the tertiary hospitals, we can rest assured. Next year, we have to take Xia Xia back to our hometown. There are not many old people in my home village who love to pay attention to them. People must be prepared in advance."

"I haven't been back to my hometown in a year," Dad sighed, "My parents said on the phone that they want to see Qiuqiu and Xiaxia..."

Mother sneered coldly: "Come on. Your mother is not eccentric for a day or two. She only has grandchildren in her eyes. How can there be granddaughters?"

"In front of the child," Dad pointed at Lin Zhixia, "Don't talk to me like this."

Mother opened the cash box, found out 72 yuan and gave it to Lin Zhixia. Mom also coaxed her: "Xia Xia, you are 9 years old this year, and you are a little adult. You can no longer be afraid of injections. Vaccination is a good thing. You must know more than mom, so mom won't talk more. "

Lin Zhixia looked dull. She accepted the 72 yuan in silence, and walked slowly to her bedroom.

She recalled the experience of getting injections when she was a child, as if she had gone through the scene again. She used a handkerchief to fix the 72 wallets and tied the knot before stuffing the handkerchief into the bag.

The night sky is vast, the evening breeze is light, and the faint moonlight shines through the glass windows, but is completely covered by the bright lights in the room.

Lin Zhixia was holding her rice bowl and sitting at a round table, eating dinner quietly.

"Big Windmill" is being shown on TV, and tonight's show is the animated version of "Journey to the West". Monkey King held the golden cudgel, leaped up into the air, swung the baton, and smashed the bones into ashes on the spot, so majestic!

Lin Zeqiu yelled: "Good fight!"

He turned his head and looked at his sister: "Lin Zhixia, what did you do? I was slouched for dinner."

Mom gave Lin Zhixia a chicken wing: "Xiaxia, what are you thinking about?"

Lin Zhixia grabbed the chicken wings, but did not respond.

Tonight’s chicken wings are braised chicken wings cooked by mother calmly. The meat is tender and delicious, and the heat is just right. Lin Zhixia was eating while thinking about how many good days can she live like today before she gets the hepatitis B vaccine?

The abnormal behavior of the younger sister caught Lin Zeqiu's attention.

Lin Zeqiu put down his rice bowl, leaned slightly, approached Lin Zhixia's ear, and shouted: "Hey! Lin Zhixia!"

Lin Zhixia was scared to death by him.

Mother was so angry that she cursed: "Lin Zeqiu, what's the matter with you, so scaring your sister! You are her brother, there is nothing like a brother should be!"

Lin Zeqiu bored his head and grilled rice. After taking a couple of mouthfuls, he said, "I think she is always in a daze..."

Lin Zhixia refused to admit: "I'm not in a daze!" Holding her chopsticks, she pounded the rice in the bowl: "I'm just thinking about getting a vaccine."

"You are nine years old, are you afraid of getting an injection?" My brother mocked her mercilessly, "Girls are squeamish. I fought with someone at the age of seven, and my knee cracked. I didn't say a word."

Lin Zhixia sneered: "When you were seven, you peed once in bed."

She described the situation in detail: "Mom and Dad took us back to our hometown. You dare not go to the toilets in the countryside. You are afraid of bugs in the dry toilets. Boys are really courageous... as courageous as my brother, seeing a bug, people I was in a panic."

Lin Zeqiu was stabbed in the sore spot and fought back fiercely: "When you were seven years old, where was better than me? You are afraid of the dark, afraid of ghosts, afraid of aliens catching you, so you always have to go to your bedroom and coax you. You are asleep. I have never seen a girl who is more cowardly and weak than you!"

"So what!" Lin Zhixia's face suddenly turned blue and red, "Mom likes me, and mother is willing to coax me! My brother always quarrels with me, and it is even more impossible for my mother to coax you!"

Lin Zeqiu buckled the bowl heavily on the table: "You think everyone is like you! I'm not rare!"

Lin Zhixia stared at him: "No, I can see it, you envy me very much."

Mother patted Lin Zhixia on the shoulder: "Xiaxia, stop talking, eat quietly. The food is almost cold."

Then, her mother turned her head and warned her brother: "Lin Zeqiu, don't pick things up at the dinner table and let your sister finish the meal. She is only nine years old this year, and you are three years older than her, so why can't you let her be a little bit? You have to fight with her! Your sister is so small and skinny, how can she not eat well?"

Lin Zeqiu let out a dull "um".

The indoor lights are shining on him, his short hair is a little messy, and the emotions in the corners of his eyebrows and eyes are hidden. He kept restrained silence, and there was no sound of eating.

Lin Zhixia stared at his profile. After a while, she secretly picked up one of the largest chicken wings, put it in Lin Zeqiu's bowl, and poured some soup on him with a spoon.

He began to say coldly again: "Who wants your chicken wings."

His mother glared at him, and he changed his words dryly and said, "Good, delicious."

After dinner, Lin Zeqiu was washing dishes in the kitchen, and Lin Zhixia was reading in the bedroom.

On Lin Zhixia's desk is a book called "Computersystemarchitecture". She borrowed this book from the Provincial Library. The new book published in 2003 is very popular and popular. There are many people lining up for it.

Lin Zhixia has been waiting, and finally it was her turn the day before yesterday. The librarian called Lin's family as a notice, and Lin Zhixia went to the Provincial Library on the same day and only then invited the book into the house.

Last night, she took the time to read more than half of the book. This morning, she basically read the entire book.

This book mainly describes computer system architecture. Lin Zhixia has been studying this direction recently. She wants to make PCB components, design circuits, operate FPGA electronic boards, and make a computer CPU by herself.

Her ideas are wonderful, but the reality is not close to humanity. In order to fulfill this wish, first of all, she must have money. Secondly, she should have a workshop. The above two points are not easy to achieve at home.

Lin Zhixia temporarily forgot the hepatitis B vaccine.

In the kitchen, Lin Zeqiu washed the last bowl and wiped the water drops in the bowl with a clean towel. He packed the cabinets and cupboards, and finally had time to finish today's homework.

When passing by Lin Zhixia's room, Lin Zeqiu saw that Lin Zhixia was sitting at the desk blankly, seeming to be struggling with something important.

He tapped on her door and said, "Lin Zhixia."

Lin Zhixia answered badly: "What are you doing?"

Lin Zeqiu walked into his sister's bedroom: "Are you still thinking about that vaccine?"

He didn't mention it. His mention immediately aroused Lin Zhixia's worry.

"I don't care..." Lin Zhixia tried to convince herself, "I don't care at all."

Halfway through speaking, she left the desk, found a stuffed penguin, and held the penguin tightly in her arms.

Her entire face was buried in the gray fluff of the penguin, which reminded Lin Zeqiu of her mother's words-your sister is only nine years old this year, can't you let her be a little bit?

Yes it is.

Although Lin Zhixia has a good memory, strong comprehension, and high IQ, she is only nine years old after all. She is still afraid of the dark, afraid of ghosts, afraid of aliens, afraid of strangers, afraid of going to the hospital for injections.

Lin Zeqiu sat on a chair and said to her, "Hey, Lin Zhixia."

Lin Zhixia looked up at him: "Do you want to scare me again?"

"What are you doing, you always think of me so badly," Lin Zeqiu said impatiently, "I tell you, when you have an injection, don't stare at the needle like a goose. Can you close your eyes?"

Lin Zeqiu recalled the past: "The year before last, when you were seven years old, your parents took you to the hospital for an injection, and I was there. The nurse took your hand, and you kept looking at the needle, and you kept crying. Who would get an injection like you? That way, staring at the nurse?"

Lin Zhixia was extremely wronged: "I..."

She couldn't speak a complete sentence.

"Take a deep breath," Lin Zeqiu told her, "Before the injection, you take a deep breath, close your eyes, and trust the nurse. Things that are over in less than a minute are worth worrying about until now? Don't waste your precious time on this meaningless Things."

Lin Zhixia held the two wings of the little penguin doll: "Brother."

The elder brother speaks softly, and the wording is rude: "Say something quickly."

Lin Zhixia asked him, "Brother, are you comforting me? Thank you, brother! When you feel scared, I will also help you. For example...Next time you see a bug, I will help you to get a bug. Shoot to death."

Lin Zeqiu neither admitted nor refuted. He stood up and left Lin Zhixia's room.

"You ignore me again." Lin Zhixia accused.

Lin Zeqiu stood at her door and said, "Please, I want to do my homework. I have a math test paper and an English test paper to write tonight. I am not like you, I can't solve a problem in one second. You be honest, don't come. Bother me, don't pester me."

"I don't want to care about you." Lin Zhixia declared.

"That's great," Lin Zeqiu replied, "I have nothing to say to you."

After he finished speaking, Lin Zeqiu walked back to his own bedroom. He turned on the lamp, poured out his homework from his school bag, and placed them on the table one by one.

The table lamp is bright, and the light yellow halo is falling, illuminating a warm mood.

Lin Zeqiu opened the curtains, the night sky blurred the lights of thousands of houses, and several lone stars were faintly discernible in the night sky. He dragged away the chair, sat down casually, held up a black pen, and focused on his math homework.

Today's math homework is a test paper.

It took Lin Zeqiu forty minutes to write the last question, and his thinking suddenly encountered obstacles.

The last question is an additional question, the question type is very flexible, Lin Zeqiu suspects that this question exceeds the outline of junior high school mathematics.

He meditated for twenty minutes before remembering that he still hadn't finished his English homework. If he spends too much time on math, he will fall asleep very late tonight.

But he is the math class representative in the class.

Tomorrow morning, the head teacher, that is, their math teacher, will let the whole class exchange test papers and mark each other's scores. The class teacher will correct the test papers while introducing the problem-solving methods.

It is feasible to give up additional questions. However, Lin Zeqiu's face as a mathematics class representative will not be able to bear.

He sighed softly.

Outside the bedroom door, Lin Zhixia's voice floated: "Brother."

Lin Zeqiu suddenly turned his head: "What are you going to do?"

Lin Zhixia ran into his room, "Twenty minutes ago, I came out to pour water and saw you in a daze. Twenty minutes later, you were still in a daze... Why? Brother?"

"There is no why," Lin Zeqiu covered his test paper, "Don't talk nonsense, take care of yourself."

Lin Zhixia brought a chair and placed it next to his position. She sat unceremoniously at the table, trying to peek at Lin Zeqiu's math test paper.

Lin Zeqiu was very determined and refused to let go. Lin Zhixia grabbed his fingers and read the questions from his fingers.

She had guessed the intention of the person who wrote the question without even seeing the complete question stem.

She seriously reminded: "This problem can be proved by mathematical induction. After all, the difficulty of junior high school mathematics is not high, and induction is sufficient. You can transform this proposition into...for the set of positive integers in the problem For each element in N, there is a corresponding ordered array of real numbers A. When n is less than 2, the condition is obviously true. When n is greater than or equal to 2, the newly added array data C should be..."

Lin Zhixia wrote a simple and easy-to-understand equation.

Lin Zeqiu caught the flash of light in his mind. Under the guidance of his sister, he successfully completed this additional problem in four minutes.
