The whole world thinks I'm a scumbag

When Gu Fangwei entered the laboratory door, the experimental platform in the middle of the laboratory was already surrounded by people, and it was very lively.

It was night, the other classes were all over, only the competition class laboratory was brightly lit.

He was carrying a large bag of things in his hand—sealed iced soy milk, rice ball fried skewers, potato chips and hot dogs, etc., for four people.

Gu Qingfeng was almost annoyed to death by him, but in the end he sent him some money.He had the funds to change the shell of the little robot and upgrade the customized hardware. After much deliberation, he didn't know how to use the rest, so he bought some food for Lu Xingyin.

I can't explain why, he and him haven't seen each other for two days, and there is no contact between them, as if the relationship has faded a bit.

Today, Gu Fangwei realizes that his connection with Lu Xingyin is just like Lu Xingyin's temperament, quiet and detached.All the intersections they can have are based on Qingmo No. [-] Middle School.

He went to class so we could see each other.He didn't go, so the two broke off contact.

Lu Xingyin will not take the initiative to come to him, and occasionally, like last time, he will suddenly go to another city far away without saying a word. In that city, he has not mentioned, and Gu Fangwei has nothing to say know the past.

Huang Feijian stood guard by the door, paying attention to the people in the Academic Affairs Office.After seeing him coming, he noticed him: "Hey, Gu Shen, you're here? What, it smells so good——"

The boy by the door took off his scarf, revealing a delicate and sharp face, with dark and shiny eyes.

At a glance, he saw that Lu Xingyin was surrounded in the middle, two experimental tables were separated in the middle, and the titration equipment was neatly placed.

"What happened to the little calculator?" Gu Fangwei asked with a frown.

Huang Feijian said in a low voice: "—Zaibi Titration!"

He told Gu Fangwei the cause and effect.

Gu Fangwei put down the things in his hand, leaned against the door, looked serious, and frowned. "Say he cheated in the competition?"

Huang Feijian could clearly feel that Gu Fangwei's whole body tensed up immediately after hearing the word "cheating", his thin lips were pursed, and his eyes became a little colder.

He remembered who Cheng Minjun was. He had seen this person talking to Lu Xingyin at the gate of Class [-] last month.

He seldom remembers other people's faces, only that scene is quite impressive.

In acid-base neutralization titration, a solution of known concentration is used to neutralize a solution of unknown concentration, and the concentration of the unknown solution is deduced by the required solution volume, and an indicator is used as an indicator in the middle to judge whether it is completely neutralized.

This titration operation generally needs to be averaged three times in the competition experiment operation, so as to reduce the possible impact of errors.

A series of operations, including the rinsing operation of the preparation before the experiment, the recording of the initial reading, and the titration itself.Theoretically, the end point of the titration should wait for half a minute without fading. However, the regional chemistry competition was aimed at junior high school students. Repeat operation starts after five seconds.

Erlenmeyer flasks, glass rods, burettes and other experimental supplies were placed on the table. Someone with good intentions recommended personnel, and Yingcai and Qingmo No. [-] Middle School each sent one person to "propose the question". Zhong and students from Yingcai Middle School jointly prepared the sodium hydroxide solution to be tested.

"Acid titration, the school laboratory only has acid burettes." Someone said.

After 10 minutes of preparation, the solution to be tested was brought up, and Lu Xingyin and Cheng Minjun were assigned the corresponding equipment.

"Stand back! The two people who just prepared the solution went out first to prevent interference with the results. It is now 27:3, and we will start the timer in [-] minutes. Who has a mobile phone?"

"I have." A lazy voice sounded by the door, Gu Fangwei took out his phone and shook it.His mobile phone is not a domestic brand, it is specially customized by Gu's, simple and elegant, and the shooting accuracy is extremely high.

Lu Xingyin followed everyone's gaze to look at him, was stunned, then lowered his head and smiled.

The eyes of the two met at this moment, Gu Fangwei didn't know why, seeing Lu Xingyin smiling like this, he wanted to be scratched by the kitten's paw again in his heart.

He slowed down his voice: "...I will record the whole process."

He'll be here watching him.

Timing begins.

Cheng Minjun quickly grabbed the glass rod and burette in front of him, and started the preparations before the experiment. The action was so hasty that it made a very loud noise.

The people around, even the students of Yingcai, couldn't help laughing—this overly eager desire to win seemed somewhat ridiculous and embarrassing to them.

Lu Xingyin was on the other side, but there was no fluctuation.He was holding the burette steadily while moistening, and on the other hand, he said softly: "Also, I don't know if your memory is wrong. I can't go faster than 20 seconds, and the preparation work is more than this time."

"I saw it with my own eyes, not counting the preliminary preparations. You just shook it a few times and changed it a second time, a third time, and then filled out the report."

Because Cheng Minjun was impatient, his breathing became a little short, and he lowered his voice and said: "—Bijibi, stop talking about these things to disturb me! Why, I think I'm about to lose, so I'm adding it at this time, do you want to get away with it?"

"No."

The laboratory was quiet, everyone held their breath, Lu Xingyin smiled: "You mean... like this?"

He rinsed the acid burette, exhausted it, picked the zero, and methodically introduced hydrochloric acid of known concentration.

Gu Fangwei glanced at it, ten seconds had just passed.

Unlike Lu Xingyin, his movements are actually very fast, but fast and steady, without shaking hands, and without hesitation in recalling the operation steps.He was naturally adapted to these equipment and operations, just as he had quickly become familiar with every mechanical part in the winters of the past few decades.

The titration operation starts.

Lu Xingyin leaned over slightly, adjusted the titration piston with one hand, and gently oscillated the Erlenmeyer flask with the other. His slender, pale wrist was shaking slightly with a steady strength and frequency.

"Damn it, look what he's doing! His buret is dripping! What can this flow rate do?" Someone quickly discovered the abnormality——Lu Xingyin was completely different from what was said in the standard experimental operation. One drop Instead of titrating with one drop, let the solution fall very fast.

In the middle school experimental titration operation, the first requirement is to be slow, slow enough to be meticulous, and it is best to be accurate to one-half of the last drop, and gently scrape off the wall of the conical flask.

And when it comes to college, some tutors even ask for accuracy to be as low as one-quarter, and even more devilishly, there is one-sixteenth drop.

Lu Xingyin completely violated this operating law!

"Fuck, the way is really fierce, is he so fierce?" Huang Feijian rubbed his eyes, although he was surprised, but he didn't seem very surprised.

Yi Qingyang said silently at the side: "...you forgot that he took away the deduction book last time, Xiao Lu seems to be... always pretty..."

Shen Ke looked at Lu Xingyin seriously: "Is he relying on guessing? It drips out so quickly, and then there is a general range, rounding up the answer?"

"He will not."

This sentence was said by Gu Fangwei.He didn't let go of Lu Xingyin's eyes, then looked down at the time of the video on the phone.

In less than five seconds, the first round of titration of Lu Xingyin ended.

On the other side, Cheng Minjun was still staring at the color of the solution in the Erlenmeyer flask, holding the mouth of the bottle, and shaking it after a while.

Lu Xingyin changed to a Erlenmeyer flask, put hydrochloric acid of known concentration into the buret again, and still slowly placed the piston.

This time, his speed was faster than last time, but he slowed down when he was approaching the end of the titration, and became a little slower, watching the scale carefully.

He leaned over, holding the mouth of the bottle with his fingertips, and when he looked up at the scale of the burette, his eyelashes seemed long and curled up, and his dark eyes were extraordinarily deep, deep and energetic, illuminated by the electric light above his head.

The solution in the Erlenmeyer flask changes color, and the second round of titration ends.

15 seconds passed.

Deer Walking Yin began to seamlessly connect with the third round of titration.

At this moment, Cheng Minjun next to him had just finished the first round of titration, and leaned over to write down the numbers on the paper.

The onlookers quickly discovered another point about Lu Xingyin: he didn't use paper notes to count at all, as if those numbers and concentration conversions were all engraved in his mind at the beginning.

In the third round of titration, Lu Xingyin really slowed down, and performed the titration at a speed similar to that of Cheng Minjun's first round.

The last half drop of the solution rolled down into the Erlenmeyer flask, and the solution changed color. After shaking, the color became so light that it almost disappeared.

Lu Xingyin put down the instrument in his hand, picked up the pen next to him, without any pause, and wrote down his final mental calculation result on the blank draft paper next to him.

He put down his pen and said softly, "I'm done."

Bring the pre-operation time, a total of one minute and 20 seconds.

Cheng Minjun took a deep breath—he was still in the second round of titration, Lu Xingyin's words completely angered him, and reminded him of the pressure he felt in the examination room a year ago—to write the test paper, Mr. Lu Xingyin It is the fastest to finish writing, almost without using scratch paper; he is also faster than anyone else in experimental operations.

Just after the theoretical score was released, some people talked about it: "Have you heard? This regionalization competition has revised the test paper to reduce the score. The experimental test in province S was earlier than us, and one person did not get the first place because of the reduced score." , committed suicide."

……

There is no cost to reporting, so why not?The clean is clear by itself. If Lu Xingyin is really clean, why is there no further prosecution after being reported?

He later saw Lu Xingyin's cheating notice, half a year later his score was cancelled, and he was stuck in the middle school entrance examination.In the middle of the time, he didn't know what happened, but although the process was long, the result still came out.

This result reassured him.Since he was a child, he has been one of the children who are known as "smart". He is always the first and can always stand out among all the children.

Lu Xingyin, a little country bumpkin from Dongtong City, was the first person to bring him pressure.

He absolutely does not allow this pressure to continue!

"Don't get distracted, keep doing it!"

The student Yingcai next to him cheered him up, "He may be deluded, or he may be wrong! Don't panic!"

Cheng Minjun's breathing trembled a little, and the speed at which the solution fell drop by drop, in his eyes, the time seemed to be stretched infinitely, which made people feel anxious.

He tried his best to stabilize his emotions, but with a slight voice, everyone present was stunned.

It was a small splash, like the sound of petals breaking.

Part of the solution in the Erlenmeyer flask was splashed out by him shaking.

The scale of the Erlenmeyer flask was imprecise, and the lost volume could no longer be calculated. His single mistake directly ruined the entire second titration.

After Cheng Minjun was stunned for several seconds, he gritted his teeth and started the third titration.

After a full 5 minutes, Cheng Minjun finally completed his titration, and then began to calculate and fill in the final number.

"How much? How much have you written?"

At this moment, Lu Xingyin turned over the white paper in his hand for everyone to see.

0.75mol/l

At the same time, Cheng Minjun's paper was also turned over.

0.7mol/l

"What's the answer?"

Someone yelled outside, and the two students who had written the question were shivering in the corridor.

Two overlapping voices came from the wind: "[-]! We have mixed the concentration of [-]!"

"Deer Walking Yin is right! He only took a minute and a half! All the titration operations probably took less than 1 minute!"

"Impossible!" Cheng Minjun's face was ashen, "You can't be so fast. You must have used some other method!"

He said exactly the same thing back then.

Lu Xingyin said calmly: "It's really possible."

"There are also ways. Take the upper limit of the approximate range for the first time, the lower limit of the approximate range for the second time, and the fine titration for the third time. I have been doing this to save time." Lu Xingyin said, "It can be faster, that is, I The situation at that time - when the approximate range was taken for the first time, it just happened to hit the result value precisely. The difficulty of the junior high school competition experiment questions will only stop at one decimal place, 0.6mol/l. Once you hit it, you know it is the standard Answer."

"My mental calculation is very fast, so I don't need to spend time making drafts." Lu Xingyin said softly, "If you don't believe me, we can continue to try."

"Impossible - you can't be such a coincidence, you are cheating, you have never taken a competition class, and you are the first in experimental theory, who would believe it? Do you think you are a genius? Are you a genius who will come to Qingmo to study? I—" Cheng Minjun stared blankly at the class, and roared with red eyes, "You must have cheated! You cheated to get such a good grade! Who would believe that you went from over 100 in the grade to second in the exam in one month, ah, you guys Who believes it?"

The laboratory was silent and silent, watching all this dumbfounded.

By the door, Gu Fangwei turned off the video, put down his hands and walked into the laboratory.

He was depressed all over, and his eyes were already icy cold.

Lu Xingyin thought he was coming to find him, but he didn't - Gu Fangwei stopped beside him, and his eyes were on Cheng Minjun.

Without saying a word, he directly punched and swung Cheng Minjun's glasses with a beautiful movement!

Holding Cheng Minjun's collar, he said in a cold voice: "Come on, don't you like to talk, come to Dad and talk, Dad will listen."

Another punch!

Cheng Minjun was beaten so hard that he hit the experimental platform backwards, his whole body wobbled and couldn't stand still.

The girls screamed, and the boys next to them rushed over to fight, and the whole laboratory was in an uproar!

Lu Xingyin rushed up to grab Gu Fangwei, hugged his arm and dragged him towards her.

Gu Fangwei didn't move anymore, but his eyes seemed to be on fire, and his usually delicate and beautiful face looked extremely aggressive.

He lowered his voice and said, "Hey, my brother is fighting. Stand far away, don't get hurt."
