"It should be fine now......"

Jiang Yucheng can't remember how many failures he has experienced - since he was a child, he has never felt so frustrated as he has in the last two weeks......

In the first week of June, the National People's Congress also entered the examination week -- Jiang Yucheng and his department entered the examination relatively early, and they all completed the examination in a week, including the minor courses. In other departments, www.biquge.info exams are scheduled much later—like Xiaoqi's history department, the final exams don't end until the first week of July. Then, according to the arrangement he had agreed with Lao Xu before, Jiang Yucheng entered the laboratory as an undergraduate student and started his own project.

When he was making soy sauce in the laboratory before, Jiang Yucheng thought it was quite interesting - at that time, he was still suffering from the fact that he could only help his brothers and sisters, and he was eagerly looking forward to when he would be able to complete the work independently. In addition, Boss Xu promised to give himself some easy-to-do projects and let himself post articles as soon as possible, so that he could use the school's national award quota to study abroad for a doctorate...... So, with the excitement of new things and the expectation of a better future, Jiang Yucheng started his work full of enthusiasm.

However, it has only been more than two weeks now, and Jiang Yucheng's enthusiasm has begun to decline at an alarming rate - organic experiments, as a "teaching", or "performance", do indeed seem interesting, but in practice it is completely different. The whole process is complex and cumbersome, extremely time-consuming, and has very little fault tolerance, and in many cases if one step is done wrong, the whole process will be negatively affected - and even a complete failure will have to be repeated.

Now Jiang Yucheng has begun to do his own project - naturally he needs to take responsibility for his own products. In the past, when he was working in the laboratory, he only had to do what his brothers and sisters had to do—but now, the timing of crossing the pillar and the like was completely up to him. The slightest mistake can lead to impurities or even missing the product - and then the entire experimental data will become so bad that it can be completely unusable. In this way, it can only be "victory and defeat are a common thing in soldiers, and the young man please start over" - that's right, it is literally "passed".

An article requires about 30 sets of data - and Jiang Yucheng spent a full two weeks doing more than 10 sets of experiments repeatedly, and only two sets of data were obtained, one of which was still impure and mixed with too much debris and needed to be reworked. Lao Xu Xuan's topic itself is indeed relatively simple, and there is no high difficulty - most of the things that need to be done are sure to be done, but even so, Jiang Yucheng still stumbles and is extremely difficult.

Jiang Yucheng's hands-on ability was not good since he was a child, and when he was young, he often broke things with his hands, and when he was older, because he had to cook for Shanshan, he finally learned to stir-fry after a lot of trouble - but his stir-fry skills are actually just "able to cook food safely......

Moreover, even if the delicate hands-on operation and timing judgment required for the entire experimental process are completely smooth sailing, in the most smooth case, the experiment will still last for a very long time - even for a skilled senior sister, it will take more than two hours to pass a column, and if Jiang Yucheng is replaced, it will obviously take a lot more. The whole team started work at 8 a.m. every day and left after 7:30 p.m. -- in many cases until after 9 a.m., six days a week, every day at such a high intensity.

In this way, after returning home every day, Jiang Yucheng basically has no time to do anything else, just take a shower and go to bed - because he goes out early in the morning, does not eat at home at noon and night, and the communication with Shanshan and Xiaoqi has not been carried out much since the end of the comic exhibition; and because there is little time at night, the "Armored Force" that is being updated is basically in a state of semi-abandonment - the communication with Yu Baochen has also become less.

"I have an idea for Blabla......"

"I'm working now, I'll get back to you later"

“…… You're going to get busy first......"

The text message contact between the two people has now been simplified to this point - in this way, Yu Baochen naturally does not contact Jiang Yucheng much. In the final analysis, physical exertion is actually secondary - the biggest trouble is mental exhaustion. Jiang Yucheng has also encountered a similar feeling when writing or programming in the past - writing a wonderful story, or the program running normally, is exciting and interesting, and in order to make the story continuous, you have to do the watering, or the repeated DEBUG in order to make the program run, are all boring.

In short, heavy and uncreative work is inevitable in order to get exciting results - but the problem is that when it comes to writing, you can try to reduce the uninteresting parts, and work like DEBUG, using specific strategies, and a strong IDE can also be effective in improving efficiency. However, there is no way to reduce the number of things like experimentation in any way - and compared to the other two, experimentation is outrageously less forgiving: you can save articles or code, but you can't do experiments......

However, Jiang Yucheng felt that he was not hypocritical enough to the point that he couldn't stand it - the master's and doctoral students in the laboratory were on vacation in the third week of July, because the MRI machine in the department needed to be shut down for maintenance during the holidays, and even if his home was near the school after the holiday, he would not have the opportunity to continue experiments.

In other words, at the beginning of the next semester, before the start of the undergraduate course, I have a month to do experiments -- during this period, if I can produce as much data as possible that can be used, then the greater the chance that I will issue a first-author paper during my undergraduate years -- for chemistry students, "undergraduate papers" are completely equivalent to "academic masters" and "promising futures"...... In contrast, everything else should be put aside - anyway, after the holiday at the end of July, you can still do these things yourself!

The pillar is finally over - this time it is finally a relatively pure product. This time it should be fine, right...... Jiang Yucheng thought about it as he inserted the flask containing the solution he had worked so hard to get on the head of the rotary evaporator, and then directly pressed the knob to turn on the steaming......

"Plop!"

"I'm !!"

Jiang Yucheng was dumbfounded on the spot - he rushed to the water bath with his hands in a hurry, but unfortunately the tragedy had already happened and there was no way to undo it......

The working principle of the rotary evaporator is to keep the inside of the vessel to evaporate at negative atmospheric pressure by pumping air. This has two effects: one is to reduce the air pressure in the container, so that the boiling point of the organic solvent to be evaporated is lowered, and the other is to let the atmospheric pressure "nail" the flask to the container interface so that the flask does not fall off while spinning.

And just now, Jiang Yucheng was negligent and forgot that he hadn't turned on the air pump yet! As a result, as soon as the rotary steaming started, the flask fell directly into the water bath filled with water below......

An accident of this magnitude was not dangerous - but the consequences were catastrophic: Jiang Yucheng's product solution was poured into a water bath and completely lost...... In short, from last night to this afternoon, everything Jiang Yucheng did was completely blind.

Suffering such a heavy blow, Jiang Yucheng sat down on the chair in a gloomy manner - a similar disaster had been encountered when he was doing Galgame before. However, after decades of rapid development, the current software engineering industry is no longer the weak chicken of the era of "The Myth of the Human Moon" - although it has to face new problems and new challenges, there are still many real progresses.

Modern mainstream version management tools can easily deal with this kind of thing - Jiang Yucheng and Jin Xuesen originally opened a private repo on GitHub with student accounts, and it is not uncommon for the code to be incorrectly overwritten, as long as they use Git to roll back to the most recent version. There is nothing wrong with the fault tolerance and robustness of the software engineering activity as a whole.

However, organic experiments are completely different - unless Jiang Yucheng has the superpower of directly manipulating molecules like the protagonist in his book, such a small negligence can completely destroy all of Jiang Yucheng's efforts. The solution is basically to start all over again - although he could theoretically use the huge separating funnel in the laboratory to extract the entire water bath, but the operation is extremely cumbersome, unless it is an extremely precious raw material, it is completely worth the loss, and it is more difficult than doing the experiment again......

An unprecedented sense of powerlessness began to hit Jiang Yucheng - he sat in his chair and didn't continue to do anything, just swiped his phone aimlessly. It's already four o'clock in the afternoon -- and if you want to start from scratch, there's no time left -- because you need to refill the raw materials and re-frame the reaction. The whole reaction takes five hours, and even if I have the reaction on the shelf, I want to collect the product before the laboratory closes, the time is too tight......

Really, what are you so busy about...... The continuous setbacks made Jiang Yucheng want to retreat a little.

"How's it going, Yucheng, how's it going?"

A somewhat familiar voice sounded in his ears - Jiang Yucheng looked up and saw that it was Senior Brother Ye in a white coat. Although his own subject has little to do with Jiang Yucheng, and the location of the experimental table is not next to each other, for some reason, this Senior Brother Ye seems to pay special attention to Jiang Yucheng's side......

"It's a bit troublesome......" Jiang Yucheng replied dejectedly - at the beginning, he still had the leisure to call himself a "future star" and despise this Senior Brother Ye, but now, he has no confidence to do anything to Senior Brother Ye anymore. After all, Senior Brother Ye is already a veteran of Yanyi, and he must be much more proficient than himself in terms of operation, "Senior Brother thinks I should deal with it?"

"Actually, you don't have to fight like this......"

What Jiang Yucheng expected was Senior Brother Ye's life experience as an elder - some practical tips and tricks in the experiment, but Senior Brother Ye said something else, "You are only a sophomore, how good is it to go out and have fun during the rare summer vacation, how good is it to rest and rest......?"

"Ah, I'm fine anyway...... Just do it......"

Jiang Yucheng casually said perfunctorily-Just kidding, I won't give up! Everything is difficult at the beginning, but after this stage, I will definitely get better! I am different from their group of people, but I want to go abroad to study for a PhD in the future--Yanque Anzhi Honghu's ambition!

For the past two years, Jiang Yucheng has been in this mess for two years - at least that's what he thinks. He will be in his third year of college again, and he can't continue to wander around, he must find a definite path for himself to go on -- and as a student in the Department of Chemistry, Jiang Yucheng naturally thought of doing chemical research and continuing his studies. Although he can't say why he wants to analyze it, he still firmly believes that since he has studied chemistry, it will be no problem to continue on this road, as long as he works hard enough, he will definitely have a bright future......

Thinking of this, Jiang Yucheng stood up and decided to start a new reaction again - if he hurried up, he would still be done by night. At the same time, his contempt for Senior Brother Ye has deepened again......

Speaking of which, when I saw Xiaoqi's Weibo just now, it seemed that something was wrong-Jiang Yucheng thought while loading the raw materials. After the lab is on vacation, I have to make sure that Xiaoqi suddenly said that she wanted to close the pen on her scarf and the homepage of her work-note that it was "sealing the pen" instead of TJ, which means that she gave up writing completely, not just the book she was updating now. Xiaoqi likes writing so much, it stands to reason that she should not suddenly choose to close the pen so without warning - Jiang Yucheng feels that there must be something strange in this......

Moreover, it is time to express my feelings for Xiaoqi - it just so happens that Xiaoqi and the others also have to prepare for the final exam, and when the laboratory is closed, they will be fine. Jiang Yucheng has already made up his mind - when he is done here, he will confess to Xiaoqi and tell his heart for her.

Now it seems that Xiao Qi's favorability of herself seems to be quite high, and if she confesses, she should have a good chance of success - even if she fails, it doesn't matter, Shanshan's life has already become "normal", even if she loses Xiao Qi, it will not have too serious consequences. Although it will indeed be very painful after losing Xiaoqi, but now that I can't go up or down, I'm really sorry for my true heart - I can express the feelings in my heart loudly, even if I fail, I admit it......

Of course, this is all for the future - the immediate priority is to do the experiment as soon as possible. Jiang Yucheng thought about it while continuing to devote himself to the intense work.
