I reach the pinnacle of life by learning

Tianhai No. 1 Middle School, multimedia classroom.

Today is Saturday, not the usual class time, but the classroom is full of seats.

Two students from other schools also received a notice from Chen Kai and came from another urban area.

Teacher Chen's kind eyes swept over each small head, and his tone was full of joy of harvest: "Students, tomorrow is the preliminaries of the National Mathematical League."

The Olympiad class opened for one semester, and the number of students dropped sharply from 32 at the beginning to 21 now.People kept dropping out and new students came in.

Everyone in the class paid a registration fee of 200 yuan, ready to show off.

Competing on the same stage, in addition to students from prestigious schools with "specialized" backgrounds like them, there are also many outstanding Ye Luzi.

Some high school students focus on the road of competition, hoping to avoid the single-plank bridge of the college entrance examination with a national gold medal.Therefore, the comprehensive grades may not be well-known, but the strength of the single subject of mathematics is unsurpassed.

"The preliminaries of the mathematics league are only a little more difficult than the college entrance examination papers. The mathematics olympiad class in our No. 1 middle school is at the top level in the whole province!" When Teacher Chen Kai said this, his expression was full of pride. If you can't make it to the semi-finals, congratulations, you have created a precedent in the history of 1-year competitions in No. 12 Middle School, and you won't have to use it for class in the future."

After finishing speaking, Chen Kai let out a hearty laugh.

It's just that his jokes were so cold that no one in the audience could laugh.

Qiao Yu is not afraid of competitions, for him, this is just a different place to take the exam.

But it is clear that not everyone is not afraid.

Zheng Qinghua on one side looked like he was about to faint.

Sitting next to him was Shang Harvard, and said: "You are also in the top 10 of your grade, can you be a little bit promising!"

Zheng Qinghua cried and said, "I'm not good at math."

Shang Harvard originally wanted to comfort him, but in the blink of an eye, remembering the last monthly exam, Zheng Qinghua got 148 in mathematics and he got 144, so he immediately chose to shut up.

"Hehe, I believe in the evil of a dog-scholar like you."

Zheng Qinghua is really not good at mathematics. He has a good foundation, but he can't solve too difficult problems. Chen Kai said that his thinking is not active enough, and he doesn't know how to do problems that he has never seen before, so he suffers a lot.

Within Osaiban, his ranking usually hovers between 5-10.

Teacher Chen Kai encouraged everyone for a while, and finally said the main purpose of this trip: "The teacher has printed out the admission ticket..." He swept his eyes around the faces of the students, and said, "Chu Xining, send it here."

The tradition of No. 1 High School is to let the first in the class issue the admission ticket, so that all the students in the Olympiad class can feel the spirit of a university bully.

It stands to reason that Qiao Yu was actually number one in the Olympian class, but Chen Kai was afraid that he didn't know anyone in the class.

The rest of the students sat obediently on the stools, waiting to get their admission tickets.

Chen Kai continued: "Tomorrow is just the first test. You are lucky. The test center is in No. 1 Middle School. The test time is from 9:11 am to [-]:[-] am. Students who are far away from the school, remember to pay attention to the time. Remember to bring a pen and exam admission ticket. Do not bring any prohibited items..."

In the preliminary round, the teachers of each test center will correct the papers and select the best candidates for admission. After 15 days, there will be a rematch, also called the league.

In the semi-finals, the winning students of the whole province compete at the same time, divided into the first test and the second test, and take the test on the same day.The second test is an additional question, a total of 3 questions, each question 50 points.The total score of the two papers is 300 points.

After the rematch, the province's 1st, 2nd, and 3rd prizes will be awarded based on the results.

There are a total of 1 first prizes in the province. These 40 students can get the opportunity of self-enrollment examinations for different grades of colleges and universities according to their rankings, but basically, if they enter the top 40 in the province, they will be eligible to be sent to Qingbei.

If you can pass the self-enrollment examination, your three-year high school study career will end early.

Qiao Yu received the admission ticket and put it in the folder.

The moment he closed the folder, he met Joan's eyes who turned to look at him.

The other party turned his head unnaturally, which made Qiao Yu feel very baffled.

Since the last variety show, Qiao An has kept a low profile a lot, a little sluggish, and her grades have dropped a lot, and now she barely maintains around 50 in the whole grade.

For most people, he is still a respectable academic master; but for Joan, this achievement is an indescribable shame.

Normally, Qiao Yu would not be able to think of such a person.

But the look in his eyes was really uncomfortable, Qiao Yu thought for a moment, opened the folders, and checked them one by one.

no problem.There were hundreds of test papers, all of which were questions that he had done. Although some of the test papers were blank, Qiao Yu did have an impression. He could even recall what day and class they handed out.

There is no interlayer in the test paper, and the admission ticket has just been issued.

Qiao Yu can only attribute it to himself thinking too much, after all, the other party just gave him a look.

Being close to an important exam is indeed easy to make people nervous.

Because he was afraid of motion sickness the next day, Qiao Yu originally planned to sleep in a hotel the day before.

But the idea was blocked by others.

Chu Xining frowned, and said, "No way. The hotel is not comfortable to sleep in, and the sound insulation is not good."

Qiao Yu is a person who will not wrong himself, if he lives in a hotel, he will naturally live in a suite in a nearby big hotel.In general, the above problems will not exist.

Zheng Qinghua's house is next door to Qiao Yu's house, but he usually lives on campus, he opened his mouth for a long time, and didn't know what to say, so he could only scratch his head.

Lu Miao said at this time: "It's okay, my house has a school district room nearby, will you live with me?"

Lu Miao's junior high school grades are very good, but he has a younger sister who is not very bright. That's when I bought the house in the school district.

Both of them went to Tianhai No. 1 middle school in junior high school, but one went to No. 12 middle school and the other went to No. 7 middle school in high school.

Lu Miao's parents are not around all year round, and they hired a nanny for them in the third and third years of junior high school.Later, the brothers and sisters of the Lu family went to different high schools, and he and his sister got together on weekends and holidays.

Chu Xining tried to gain the initiative: "My house has extra bedrooms."

Lu Miao: "My parents are not at home."

Chu Xining: "Someone in my family cooks."

Lu Miao crossed his arms, and the old god was there: "My parents are not at home."

Chu Xining's fist hardened.

He lost his advantage, so he could only look at Qiao Yu anxiously: "Who are you going with?"

Qiao Yu: "..."

Why do you always feel that this sentence is weird?

Qiao Yu met Chu Xining's father, at the dinner party at Professor Lin Feng's house, at the local news station in Tianhai City, and online in newspapers.

For most people, "friend's parents" is a very disturbing existence.

Although Qiao Yu was not stage frightened, she didn't really want to see her parents if it wasn't necessary.

He pretended to be contemplative, and after a while, he said, "I'd better go to Lu Miao's house to sleep."

Chu Xining was defeated, but still said gracefully: "Okay, fine, remember to get up on time."

Shang Harvard watched the war without gunpowder smoke, and after school, he ruthlessly laughed at Chu Xining.

"You don't understand." Chu Xining said, "Don't you have a friend you particularly like? The kind that you only want him to play with you, and don't want him to play with others."

Shang Harvard's expression was blank: "Then I really don't understand. No, brother, we have known each other for almost 10 years, why don't you let me sleep?"

Chu Xining's expression was delicate: "...how about you look in the mirror?"

Shang Harvard couldn't help sneering: "Oh."

This despicable face dog!

The school district house bought by Lu's family is just across the street from No. 1 Middle School.The elevator room is on the 17th floor. The home is a two-story duplex, and there is an open-air balcony upstairs.

Lu Miao pointed to a small door at the corner of the second floor and introduced: "The outside is an open-air balcony. You can enter through this door at home, but you can also enter through the stairs. The other door was not locked before, and people often go up to this building. Planting vegetables, pouring chemical fertilizers smells too bad, and some people raise chickens, so we sealed off the top floor.”

At that time, this incident caused quite a stir in the community, and the vegetable growers went to the property.Regardless of the property, those families even called the police, saying that Lu Miao had embezzled their property.

Just the few green onions and the few nests of vegetables planted in the vegetable field.and two old hens.

"Usually no one lives in the house. The first floor is the bathroom, dining room, living room, and kitchen. The second floor has a master bedroom, two second bedrooms, and a piano room. You sleep in the master bedroom. I'll find you sheets and quilts later. .”

Neither Lu Miao nor Lu Yun wanted the other's bedroom to be bigger than their own, so it used to be the master bedroom where the nanny slept, but after the nanny left, it was always vacant.

Lu Miao opened the refrigerator and sighed: "Order takeaway or go out to eat, there is not even an egg in the refrigerator at home."

There was only a can of Coke and two wilted shallots, the tips of which were all yellowish brown.

Because there was an exam the next day, the two of them ate ordinary home-cooked food in the evening, without any chili, and the oil and salt were not heavy.When I was [-]% to [-]% full, I stopped my chopsticks.

When returning back, just as Lu Miao opened the door, he heard a familiar sound of the piano.

His heart skipped a beat, thinking to himself, it's broken.

Sure enough, several headlights in the room were turned on, and the sound of the piano disappeared in an instant. After a while, Lu Yun's figure appeared beside the stairs on the second floor.

She was still wearing the school uniform of No. 12, her long hair was slightly curly, and the end was dark brown.

Lu Miao is not bad looking, so it stands to reason that his younger sister should also be a beauty.

It's a pity that the other party has dyed dark brown curly hair, and the makeup on his face is quite heavy, so he can't see his real facial features clearly.

When he saw the person behind Lu Miao, Lu Yun's movements suddenly stopped, his expression was very shocked.

But because of her exaggerated makeup, this shock is not obvious.

Lu Miao closed the door behind his back, and frowned: "Why are you putting on makeup again? Don't you have class tomorrow?"

Lu Yun was quite rebellious in his adolescence, and the adults in his family were often absent, saying that his elder brother was like a father. Lu Miao has been heartbroken these years.

Because he is too lenient, the relationship between the brother and sister has actually been awkward all these years.

The flashpoint of the conflict was more than a year ago, when I was graduating from junior high school and choosing my volunteers.

Lu Miao had already talked with the teacher, saying that he would continue to study in No. 1 Middle School, and his sister would also stay in No. 1 No. [-] Middle School.

As a result, Lu Yun refused to do it, and she would not go to high school if she said that.

Later, Lu Miao applied for Tianhai No. 7 High School for her, but he waited until the deadline for volunteer submissions before Lu Yun told him that he had applied for No. 12 High School.

It made Lu Miao very angry.

But in fact, Lu Yun just hoped that Lu Miao would be able to retreat in the face of difficulties and return to No. 1 Middle School to continue his high school studies.

He has good grades, even if the deadline for voluntary reporting has passed, as long as the school does not start, there is always room for maneuver.

But Lu Miao didn't, so he stayed in No. 7.

In fact, Lu Yun hadn't put on makeup for a long time, and according to her usual personality, she wouldn't explain it to Lu Miao.

But for the first time, Lu Yun said: "There is a cultural performance in the school, I went up to play the piano, and I didn't have time to take off my makeup. There will be no class tomorrow."

Unlike her dress, Lu Yun's voice is soft and sweet.

... It made Qiao Yu feel a little familiar.

After finishing speaking, Lu Yun turned around and left. A moment later, there was a loud door closing on the second floor.

Lu Miao was stunned for a moment before explaining to Qiao Yu: "My sister has a bad temper and is a bit rebellious, so don't worry about her."

I was pretty good when I was a child, but why did I behave like this when I reached puberty? It must be because I was chasing stars and chasing my brain stupid!

This is the reason why Lu Miao hated a certain artist surnamed Su so much.

Qiao Yu was still thinking about where he heard this voice, and subconsciously replied: "Okay."

Then, I asked, "What's your sister's name?"

Lu Miao immediately looked at him vigilantly: "Why do you ask this? Let me tell you, my sister doesn't fall in love early, don't even think about it!"

Qiao Yu: "..."

Forget it.

On the other side, Lu Yun's heartbeat reached 180 miles, and he stood against the door, feeling a little dizzy.

Her expression was very strange, it was probably a look of smirk mixed with ecstasy...it was inexplicable.

She pulled out her phone and opened her contacts list.

Xiaoyun: Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh! ! ! !

Lord:?what's wrong

Xiaoyun: Have I ever told you that Teacher Xiaoqiao and my brother are in the same school.

The group leader clicked on the potato chips and replied: Yes, what's the matter?

Xiaoyun: Grass, shocking my whole family!My brother brought Teacher Xiao Qiao home? !

The potato chips in the group leader's hand suddenly became tasteless.

Group owner: I don't believe it!

Lu Yun secretly opened the bedroom door a crack.

It's 9 o'clock in the evening, it's not time to go to bed, and I have an exam tomorrow.

Downstairs, two people are sitting at the dining table, doing final practice for tomorrow's exam.

Qiao Yu felt that there was nothing wrong with her, but Lu Miao was a little worried.

Qiao Yu's school uniform was draped on one side, his shirt sleeves were rolled up, his skin was so white that it glistened under the cold light, his nose was high and straight, he looked like the male lead of a school idol drama.

When he was doing the questions, he was always focused on nothing else, and Lu Miao turned his back to Lu Yun, so naturally he would not find that someone had quietly taken a photo upstairs.

This photo was quickly sent to the group owner by Lu Yun.

The group leader is sour, sour and bubbling.

He was jealous, jealous of the pen in Qiao Yu's hand, the clothes on his body, the test papers spread out on the table, and the person opposite him.

Qun Chengguang gritted his teeth and said, "Wait for me! Which class is Qiao Yu in?"

He's going to go through school transfer procedures now!

On the next day's exam, Qiao Yu felt that he did well.

When it was time to hand in the papers, he followed the flow of people out of the examination room, his ears filled with complaints from other people, whether true or false.

"Damn it, who the hell made the question this time, must be out of his mind!"

"It's so difficult. I haven't solved several questions. I'm sure there is no hope..."

In fact, Qiao Yu felt that the difficulty of the test paper this time was moderate, nervous, interesting and challenging, and the person who wrote the test did a good job.

At the same time, sigh, if the math questions in the college entrance examination also have this level, it will probably be much more interesting.

And the system, which has not moved for a long time, finally released the main task again.

As soon as the task list came out this time, Qiao Yu was completely dumbfounded.

[Main task] Have a biological laboratory of your own.Requirements: Can meet the needs of high school biology experiments.Reward: 200 points, failure to deduct the next free class right.Time limit: 30 days (remaining 30 days)

Introduction: A young man who is struggling on the road of biology, how can you not have your own biology laboratory?Are you trying to dissect a rabbit at the vegetable market?

[System Task] Familiarize yourself with the basic instruments and complete 100 perfect cell slices.Reward: 50 points.There is no penalty for failure.Progress: (0/100)

Introduction: Proficiency in basic operation skills is the first step for every scientific research dog to realize the value of life.Please master the basic skills necessary for scientific research dogs as soon as possible.

Qiao Yu couldn't help asking: "How can it be considered my own biological laboratory?"

The system replied: "It's like a real estate certificate, with your name on it, it's yours."

Qiao Yu: "..."

In Huaguo, if you walk into a university and arrest a professor of science, he may have the names of several laboratory leaders on him.

Some people are fighting for scientific research and their own ideals, and some people are for the convenience of making money.

Knowledge is priceless, but investing limited money in the pursuit of knowledge may create more value.

To put it bluntly, it is to trick others into investing money and soliciting sponsorship.

There are high and low among laboratories.

The one at the top of the Huaguo laboratory food chain is undoubtedly a national laboratory.

Doctors walk everywhere here, graduate students are not as good as dogs.

The well-known old professors don't need to say a word, just a hint in their eyes, and countless companies will go through fire and water for him and throw a lot of money.

But entrepreneurs do not like to do charity. Most university laboratories or private laboratories are in a half-dead state when they have no results.

Some mentors are even so poor that they can't afford to pay the wages of wage earners.

In the country of Hua, private construction of laboratories is allowed above.But you need to go to the local construction department for approval, and you need copies of relevant certificates, certificates of conformity, health certificates...

It is obviously unrealistic for a high school student who is still in 696 to do it.

Qiao Yu finally understands why the total assets must reach 100 million before the system's 3.0 stage can be started.

No matter from which angle you think about the main task, it is very expensive.

Laboratories are not worth much, but the related products researched in them are more valuable.

But to prove that this thing belongs to you, there will be endless papers, endless investigations, endless experiments...

Without the guidance of a teacher, it is very unrealistic to achieve any results without the guidance of a teacher.

The threshold of scientific research is very high, and it is destined to belong to the path of a few people.

Under normal circumstances, if ordinary people want to engage in scientific research, they only need to start with a score of 600 in the college entrance examination, and then choose a major with strong relevance, and maintain a stable grade in the top grades. When they are juniors and seniors, they will have the opportunity to contact scientific research.

In addition to this path, there are also many "folk scientists" in Huaguo.

It's just that in academia, "minke" is derogatory.

After all, most minkes are still studying perpetual motion machines or trying to overthrow Newtonian mechanics.

Many scientific researchers in Huaguo call themselves "research dogs". They have learned a lot of knowledge and are respected by everyone in the outside world. However, they are often scolded by their instructors in the laboratory.

The pedigree of a scientific research dog also depends on the mentor who follows it.

If the mentor is a big name in the industry, then they are purebred famous breed dogs; if the mentor has no achievements, then they are ordinary working dogs.

The scientific world is cruel.

The crushing caused by knowledge barriers is like a moat, and some people spend their lives doing nothing but mediocrity.

Qiao Yu felt a rare headache: "Can a laboratory without a certificate be ok?"

If he could, he could buy a villa in the suburbs and renovate the basement.

The only problem is that Tianhai's house price is quite expensive, and I don't know if the little money in my hand is enough.It's a pity that the old house at home will not be demolished until one or two years later, or else I would have an excuse to live in a bigger house right now.

The system said: "Yes, but the system will check whether the laboratory is qualified. Please pay attention to safety and related equipment issues to the host."

Qiao Yu sighed in his heart.

It seems that I still have to find a way to earn more money, and I can't start to relax just because I won the 500 million lottery.

Teacher Chen Kai said that after the exam, we will gather in the multimedia classroom.

Qiao Yu sat on a chair and studied how to build a laboratory with the system, his expression was a little blank, and his eyes were so empty that other people subconsciously felt that he had failed the exam.

System: "By the way, there is one more thing..."

Before Qiao Yu had time to ask, a burst of calls brought him back to reality.

"Qiao Yu," Teacher Chen Kai whispered beside him, "don't worry, the usual basic set is there, no matter how bad it is, as long as you are in the top 100 in the city, you can basically pass the preliminary round. "

It seems that Mr. Chen also thought that he encountered a small problem in the initial test...

But he didn't intend to explain, just smiled at Mr. Chen to reassure him.

Chen Kai also shook his double chin slightly, nodding to show that he understood.

In all fairness, although he and Lu Miao are students in No. 7 Middle School, Chen Kai has always treated them equally and taught them with all his heart. He is a very responsible teacher, so Qiao Yu has a good impression of him.

Chen Kai continued cheerfully: "The preliminaries are finally over, and everyone can relax for a while. It just so happens that it's the weekend. I'll treat everyone to hot pot at noon!"

As soon as this remark came out, the students in the classroom burst into cheers.

Qiao An quietly raised her hand at this time, her face was pale, and she said, "Teacher, I'm not feeling well, can I go first?"

Joan, who got the permission, didn't go home directly, but after confirming that no one was paying attention to him, he slipped into the black Internet cafe near the school.

His hands trembled so badly that he could barely hold the mouse.

The full name of the mathematics competition is the National Mathematical League.

Managed by the Huaguo Science and Technology Association and sponsored by the Huaguo Mathematical Society, the topic is unified across the country.

For this competition, Joan joined many related groups in an attempt to obtain first-hand information.

Just the morning before the exam, in a small group with only more than 20 people, the administrator sent them an email, saying that someone posted a post in the early morning of Tieba and gave this thing, although it was deleted within 10 seconds, but There are still a few people who see it.

Qiao An didn't even remember when he joined this group. He thought it was a spam email, but when he opened it, he found a WPS file inside.

Out of curiosity, Joan downloaded it and found that it was actually a topic for the math league preliminaries.

Qiao An didn't know whether to believe it or not, but she didn't dare to say anything.He slowly browsed through the topics and subconsciously calculated.

Every year on the eve of the league, some people claim to have won the internal test, but they are beaten in the face every year, and most of them don't take it seriously.This is even more true for powerful people like them.

As for this set of questions...it's very fresh.That's all Joan can say, and he's interested in it.

It's actually good as an exercise.

As Qiao An was doing it, a thought suddenly popped up: If this is true, would he be able to beat Qiao Yu in the exam?

Both of them have the surname Joe, so comparisons are inevitable.

From Qiao Yu's first day in class, this kind of comparison is everywhere.He knew that he had let Teacher Chen down.

In the middle and late stages, someone in the classroom called "God Qiao", and when Qiao An turned his head, he would still have an embarrassed smile on his face.

Little did he know that Joan himself was the one who felt the most embarrassing.

He didn't understand why things happened like this.But the desire to win against Qiao Yu is getting stronger day by day, and the hope is getting slimmer day by day.

In terms of study, Qiao An has always been looked up to by others. He never expected to meet such a person one day, which made his neck sore and his eyes hurt, and he couldn't see the hope of surpassing.

Qiao An completed the math paper alone, because she didn't dare to ask Mr. Chen, and many questions were paid by other people who consulted online.

The night before the exam, Joan closed his eyes and rested on the bed, and couldn't fall asleep for a long time.

He whispered to himself in his heart, could he also send the question to Qiao Yu?

Qiao Yu's Penguin is in the class group of the Olympiad Class, and it never bubbles up, but it can be found.

In the Internet cafe, blood rushed to Joan's face. The tip of his nose smelled of disgusting smoke, and Joan felt a little nauseous.

But he didn't throw up.

He remembered that just yesterday, in the same Internet cafe, around 12 o'clock in the morning, he registered a small account, and then sent that email to Qiao Yu.

Joan chose to send at a fixed time, and the time was just 10 minutes before the exam.

It was too early, he was afraid that Qiao Yu would see it.

At that time, everyone had already entered the examination room and was waiting for the papers to be issued, so it was unlikely that Qiao Yu would be able to see this email.

Qiao An felt a little regretful after sending it, and wanted to delete the email, but was too lazy to open the email.

As soon as today's exam papers were handed out, Joan's mind went blank.

His heart beat faster, his breath became short of breath, and he met the slightly worried eyes of the invigilator several times.

This is the set of questions I saw yesterday, and the questions are exactly the same.

Can Qiao Yu get full marks in the exam?

Joan didn't know...but he started to calculate the problem according to the answer in his memory.

Now that the exam is over, Joann opened the mailbox, took a deep breath, permanently deleted the email, and quit the group chat.

The author has something to say: You can only fall in love after you are an adult.

Modification: rematch time (following the actual competition system, adjusted from September to 9 days later.)
