The whole world thinks I'm a scumbag

The training place of the national training team is Yangliu University, which is located in Jiangnan.Because the national training team screened out some players from provinces and cities, Lu Xingyin's ranking in the national training team was not 22nd in the finals, but 15th overall.Many people ranked after him had even higher scores than him.

At this time for everyone, the school affairs have basically been settled, and there is no need to worry about the future.

In the first week, the atmosphere of the national training team was much more relaxed than that of the provincial team training or the national finals.

For three weeks, they received unlimited meal coupons and canteen coupons from the cafeteria of Yangliu University. They ate in each cafeteria one by one, and then went out in a group to buy lotus root starch and chicken blood stones over the wall, and packed squirrel mandarin fish to bring back. public funds tourism".

Lu Xingyin doesn't go out much, he likes to stay in the dormitory to read or play games.The student in the dormitory with him is from N province, the same province as Milk God, and he squeezed in at the bottom of the ranking. His name is Chen Fang.He is not from the same school as Milk God, and his temperament is also very different. One is domineering, while the other is cautious and silent.

Chen Fang was a small man with black and yellow skin, and looked like a stunted junior high school student.

In the national training team, the average score of several tests after joining the team will be announced every day. Lu Xingyin ranked 22nd in the national finals. After coming, he became a blockbuster and directly took the theory-experiment double first place.

Even Cheng Ke was shocked: "Lu Xingyin, what did you go through during your winter vacation?"

They were one of the few people who knew that he had undergone an operation, and the milk god was also shocked: "Didn't you go for the operation? Craniotomy can make people smarter???"

Lu Xingyin sneered and remained silent.

If it is said that his breakthrough before participating in the finals was because he understood the difference between "examination" and "love" for the first time, then these three months of surgical training were the time for him to further understand the word "love".

There is actually no cost to liking chemistry, you just need to like it.Because of his own experience, he once misunderstood the price of liking most people and things in this world, until he walked back before the gate of hell, and he found that it was actually so easy.The crystals precipitated in those test tubes, the white mist rising in the condensation tubes - these are all given to him by this beautiful, mysterious and complicated world.

He is not for the game now, not for glory, but for his own liking.

During the three months of recuperation, he was like tasting a glass of mixed juice with rich taste, constantly reading those textbooks, sample questions, and test papers, slowly looking at those complicated and awkward English words, and the uncommon and changeable names of people.Chemistry told him the complexity of the world and every second, let him know the difference that a slight difference can make from the most subtle.

This is also a luxury that he never even dared to imagine.

From the second week onwards, the atmosphere of the national training team gradually changed. The atmosphere of tension permeated, and the smell of gunpowder seemed to gradually become stronger.

These kids were all woken up from their three-month vacation, and couldn't help but be carried away by everything on the team.Mobile phones were confiscated in the team, and only the scoreboard handwritten and registered by the coach hung outside the door of the training room, recording their achievements after the national finals again and again.Individual grades, average grades, and weighted average grades.Every child is gradually endowed with various responsibilities from the outside world—from his alma mater and from his own province.

50 people, the total score was rotated again and again, the first and last people were replaced one by one, until the end of the second week, the list at the end was almost fixed - some students chose to give up.

The national team competition itself is an opportunity for the provinces to pave the way for the next student resources, and they will desperately snatch it.Every time the mobile phone is handed out after the training, Lu Xingyin can always see some students hiding behind the wall, solemnly calling the coach of his original province, talking about the results.

When my parents came to visit on weekends, it was also the voice of a group of people discussing and planning for the future in low voices.

The first one to leave the team was a girl named Liu Cangsong.She comes from province Z in the remote southwestern region, which is also a weak province, and she is the only girl from province Z who entered the national training team and successfully signed a contract with Peking University in the past five years.

Her family background is ordinary, and her parents are considered enlightened. The national training team has always had the phenomenon that there are fewer girls than boys. It's not that girls are weaker than boys, but that competition is still synonymous with eccentricity and deviation from the norm in the eyes of most parents. There are already very few parents who can support girls to take this path, and even fewer have reached the stage of the national training team.

Milk God has always been straight and unflattering when he speaks, and he is not very polite when it comes to girls' evaluations: "There is a lot of pressure, and the weakest provinces favor the most resources. It is estimated that they have been number one all the way from childhood to adulthood. Thinking of being at the end of the Guoji crane and not being able to climb up no matter how hard I climbed, I naturally lost my mind."

At this moment, it is the 13th day when the training camp starts.

The second member who quit the team came from G City, that is, the high school attached to G University only recruited more than 100 people in each grade, and the school had a combined rate of going abroad, Qingbei, and capital expenditure of 100%.Although the reason for his resignation was not clearly stated, everyone guessed it - this year's G city training team had a bumper harvest, and there were six members of the national training team from the same school alone.

There is only one spot for the national team, and because of the same school, I know the gap between myself and my classmates, so I simply give up.

And there are still some people who don't have the courage to quit the team, refuse to let themselves go, are still struggling on the verge of being eliminated at the bottom, and just want to spend these three weeks from beginning to end.The gap between the results of this group of people and the previous group is widening, and the gap can even be as high as [-] to [-] points.

Gradually, no one went over the wall to eat squirrel mandarin fish.

In the training room, someone had a record of not going out for four and a half days—eating instant noodles to review questions, sleeping on the table when sleepy, and feeling that the time back to the dormitory could not be wasted.Scoring one more point than others in the test may cause yourself to be looked at by the judges in the final national team evaluation.

Lu Xingyin still maintained a normal routine.He sleeps for eight hours every day, brushes up the questions in the training class, goes to the laboratory to do an experiment late at night, repeats the frequency similar to the exam, and then comes back to wash and sleep.

No. On the 20th day, the test of the training team was suddenly changed and replaced with an English proficiency test--most of the candidates did not think of this arrangement, and there was chaos.In order to compete in the competition province, the content of the normal college entrance examination is generally not accumulated, let alone English, which is generally not very good at science contestants.

Lu Xingyin originally thought that he would pass the test, but what he didn't expect was that after the test results came out, he came in fourth.

Most of the top ten students are students from developed provinces and famous schools.It is needless to say that Chu Quan has been taught bilingually since he was a child, and he has no barriers to communication abroad. The remaining students from several prestigious schools have practiced real quality education since they were young.

Discussions about the national team candidates are getting more and more intense.Lu Xingyin reads the posts on the Chemical Island board every day, and sees that there are different opinions on the candidates for the national team.

The number one Chu Quan, undoubtedly the national team, the host province of the finals, has always maintained the first level in both the finals and the training competitions.

And the rest of the rankings are interesting.

One is Cheng Ke.

He was tenth in the final, and the performance of the training team has been stable in the top four.

The other is Milk God, he was sixth in the final, but his performance in the training team was a bit erratic - he was a little slack in the first week, which caused the results to fluctuate a lot.At the same time, Chen Fang, a member of the N province who shared the dormitory with Lu Xingyin, also remained high. He was shortlisted for the national training team with the last ranking of fifty, but he gradually climbed from the top [-] to the top [-], followed by the top [-]. Twenty, and now it has stabilized in the top five.

He and Milk God are in the same province, and it is unknown who will get the national team spot.

The other is the quota discussion between Lu Xingyin and Gu Fangwei.

Gu Fang ranked second in the country in the finals, but he took a long leave of absence during the training camp, and only the online theoretical results were included in the total score ranking.

National No.20 No. [-] in the final of Lu Xing Yin, the training team ranked second overall in terms of total and average points.

They are also in the same province - it is also unknown who will get the final quota.

On the last day of the exam in the third week, Gu Fangwei rushed back.

Although the previous average scores are included in the selection criteria for national team members, the highlight is still today's test results.

The written test was held in the library of Yangliu University, and the difficulty of the test questions was comparable to that of the national final.

After Lu Xingyin finished, he didn't feel any obvious blockage, and there was still some time left, so he went back and checked again.

He and Gu Fangwei were in the same examination room. When he turned over the test paper and looked up, he happened to see that Gu Fangwei had also stopped writing.She was looking at him with her chin resting on her head, her peach blossom eyes were twinkling with starlight, and she didn't know how long she had been looking at him.

Lu Xingyin's face burned, he lowered his eyes and continued to check the test paper.

After the theoretical exam, everyone went out of the library.With the test style of this year's national finals as a basis, after the theory test, the students who are sensitive to the style of the question have more or less reached a consensus-the difficulty of the theory test is moderate, so the experiment must be a moth!

Candidates received the sterilized white coats one by one, lined up to enter the laboratory, and waited for it.

Lu Xingyin walked to the experimental table and saw the experimental questions of the selection exam. The white experimental report book said the experimental topic: "Carmine Pigment Extraction and Yield Detection"

"Carminic acid is a water-soluble anthraquinone pigment, dark red powder, and the molecule is polar. Because the molecule contains 8 hydroxyl groups and 1 carboxyl group, and both hydroxyl and carboxyl groups have strong hydrophilicity, carminic acid Very soluble in water, but also relatively soluble in polar solvents such as methanol, formic acid, dimethyl sulfoxide, etc.; hardly soluble in non-polar or weakly polar solvents such as ether, ethanol, petroleum ether, toluene, benzene, grease, etc. ;No obvious melting point and boiling point, the color deepens when the temperature rises; carminic acid crystallized from the aqueous solution is bright red crystals at 130 ° C, and decomposes at 250 ° C. The aqueous solution of carminic acid is acidic, and the molecules have dissociation equilibrium in the aqueous solution .” (concepts are all references)

On the table of each test bench lay a pack of dried cochineal insects, red and dry like stones.

Someone next to him has already scolded: "Wori—is he still doing personnel work in this competition? Aaaaaaaaaaaaaaaaaaaaaaaaaaaa, I hate bugs the most!"

Lu Xingyin picked up the rubber gloves and put them on carefully, took out a cochineal insect with tweezers, and gently crushed it on his fingertips, the obvious carmine color immediately remained on the light yellow gloves.This little bug seems to be filled with this dye from top to bottom, like a fake bug stuffed with hardened pigment particles.

The staining is strong and the yield may be high.

Lu Xingyin took another look at the reagent bottles placed on the test bench.

The aqueous solution is acidic, and sodium hydroxide should be used for titration routinely, and there are many optional indicators.

But here's the first pitfall in the experiment—carminic acid itself is a titration indicator.

No more indicators are needed.

The pre-experiments followed the normal procedure until the titration, and Lu Xingyin's movements became slower and slower.

Someone next to him also carried out the titration link, and kept dripping according to the usual titration speed. No one paid attention to the abnormality here in Lu Xingyin.

Lu Xingyin hesitated a bit.

Carmine staining is so strong that it is difficult to see the end point, which is no less difficult than asking everyone to pick the correct one among a bunch of similar shades of lipstick.

He just seemed to see a slight discoloration, but he couldn't be sure if this was the end point of the titration-if it stopped here, the yield was only about 30%.

No matter how you look at it, it is a wrong titration.

His hair was slightly wet, and he didn't know whether to put down the burette in his hand, until he heard the teacher announce the last 5 minutes, Lu Xingyin pursed his lips and put away the pipette.

He trusted his intuition and took it as a gamble.

He walked out of the lab and let out a long sigh of relief.

People started asking around: "What's your productivity?"

"99.7%."

"almost."

……

Lu Xingyin walked over with his schoolbag in his arms, and walked back side by side with Gu Fangwei. He also asked him, "What is your production rate?"

"99%, but I'm not sure. I don't think this experiment went so well." Gu Fangwei noticed his strangeness and asked, "What's the matter?"

"It's nothing." Lu Xingyin shook his head and smiled, "It's just my experiment that overturned the car, it's nothing."

The results of the selection competition were announced the next day, and then, except for the four members of the national team selected, this will be the end of retirement for all chemistry competition students in this session.

In the afternoon of that day, Lu Xingyin and Gu Fang escaped from the seminar and climbed over the wall to eat squirrel mandarin fish.

There was fireworks outside Yangliu University, they queued for a long time, and finally came to the shop that was quite famous among the contestants.In the afternoon, the store was crowded, and they waited for a long time after receiving their numbers, and finally came to a narrow table for two.

It was obviously a table for two, with one on the other side, Gu Fangwei insisted on squeezing over and sitting side by side with him: "Sit separately to be cold, and sit next to you to be warm."

He still reached out to shake his hand out of habit.

Lu Xingyin's body is getting better. An example is that even in winter, his palms have become slightly warm, instead of always being cold as usual.Gu Fangwei held his fingertips in his hands and grasped them lightly, while Lu Xingyin was a little nervous, looking back and forth, left and right.However, they wear thick clothes in winter, and no one pays attention to them.

The squirrel mandarin fish and other side dishes were served.The food here in Suzhou and Hangzhou tastes sweet, even if it is not sweet, the taste is a bit salty, but the store they came to today obviously implements "sugar does not cost money" to the end - Gu Fangwei provoked a chopstick He asked for spicy mapo tofu and found that it was coated with a layer of syrup.

"Sweet." Gu Fangwei pointed to this dish, but Lu Xingyin couldn't believe it: "This can't be sweet."

After he was discharged from the hospital, he had to eat lightly. He reached out to hold a chopstick, lowered his head and used a porcelain spoon to remove the slick oil and chili powder on it. As soon as he lowered his head, his warm breath came over. Gu Fangwei tilted his head and kissed him Taking a bite, the tip of the tongue lightly touched his.

"It's really sweet."

There was a lot of voices around, Lu Xingyin was kissed by him, and the spoon was so panicked that he dropped the spoon, and there was an exquisite and crisp jingle, which made others turn around to look at them.

Lu Xingyin's ears were red to the point of bleeding, and Gu Fangwei was about to reach out to touch his head, but two men with fierce looks suddenly broke into the door—Gu Fangwei's hand stopped abruptly.

These two vicious men, one is the head coach of the national training team, and the other is Chen Chong who hasn't seen him for several months.

The two immediately sat down properly.

Seeing the two getting closer, Gu Fangwei protected Lu Xingyin's back and said bravely, "The exams are over, we won't be punished by the team if we climb over the wall, right?"

"—Punish the fart." Chen Chong rolled his eyes, glanced at their dining table, and waved his hand, "The waiter packed up these two children and took them away. We have something to go back and talk about."

Gu Fangwei and Lu Xingyin looked at each other and asked in unison, "...the national team?"

"Yes, both of you get up and do the data verification with me." Chen Chong said. "But don't be too happy, the top ten are all doing data verification."

The two had just eaten a mouthful of tofu——Lu Xingyin didn't even eat the tofu, and they were taken away inexplicably.

In the car, Lu Xingyin heard the head coach say: "There are two situations in this selection competition. One is that the student ranked No. [-] is giving up his place in the national team because he signed a contract with a foreign country to restrict entry. It is also for this reason that the student ranked No. [-] The second student will be number one, and the national team of Lu Xingyin is to be determined, and it will be no problem if it passes the review of the materials."

Lu Xingyin was stunned: "—Me?"

"It's you." The coach showed him the report card, "The theory is 99.7, and the experiment is full. The cochineal yield experiment, 50 people in the training team, only two students did it right."
