Yang Zichen was still absent-minded on the way to the chemical laboratory building, and when she met others to greet her along the way, it was basically a hasty and perfunctory end, and even some people she might have walked over before she could see it clearly, which was in stark contrast to the enthusiastic chatting with everyone she usually saw.

Such an emotion has begun to affect Yang Zichen's normal life, but Yang Zichen himself still belongs to the kind of party who doesn't know anything.

In order to provide students with a better learning environment and atmosphere, Oceanpower University has also put a lot of effort into the course of physical chemistry, which exists in experiments. Although the experiments that Yang Zichen is now exposed to are still very rudimentary, Zhao Baian has studied a lot of schedules (after all, he wants to find something that interests him as much as possible), and if he studies the same kind of discipline for four years, the experiments he does in his junior year will already be at the level of the Institute for Advanced Study.

In addition to artistic talents, Oceanpower University also attaches great importance to the cultivation of basic research talents. Its negative floor is embedded in various laboratories, which contain a large number of precision instruments, the reason why it is placed underground is not because there are any secrets, but simply that almost every large instrument is too heavy, at least several tons, if it is placed on the floor or on the ground, the ground will subside.

As far as Zhao Bai'an knows, one of the more famous ones in Haichuan University is a press, don't listen to the ordinary name, it can easily press graphite into diamonds, there are only three in the world. For scientific researchers, such high-end instruments are like huge treasures, buried underground. The experimental conditions that students can have have have made many researchers from the outside world jealous.

It is precisely because of the blessing of these awesome instruments, coupled with the fact that Oceanpower University encourages students to find professors to collaborate on research if they have any ideas, basically by the time of their senior year, there are always many students who can publish highly influential research papers. In addition to the three giants of Nature, Science, and Cell, there are also some SCI journals. In the eyes of outsiders, they are all proud achievements, but the people of Haichuan Dali are no longer surprised.

In order to give a good training to outstanding students from all over the world at the beginning, if you choose to study physics, chemistry and biology, all courses are designed in parallel with theory and experimental operation, and students are mostly connected through experiments during class. The evaluation criteria for laboratory classes and even various exams are stricter than those of some test-taking subjects.

Before each laboratory class, the teacher has to spend half an hour to an hour to talk about the experimental specifications, after all, chemistry experiments are especially related to life safety issues. Although it is all a small fight at present, if you don't develop a good habit from now on, you will have big things in the future. There have been at least eight large-scale explosions in history that Haichuan Dazhao Bai'an was able to find.

In order to avoid any problems in the operation, the teacher decided to emphasize the precautions for the students in advance in the last 30 minutes and remind the overall process of the experiment again.

Throughout the class, Yang Zichen kept looking at the teacher with one hand and explaining various steps to them. Of particular importance are the purification of the solution and the flame reaction. Because there is no mandatory requirement that students who choose chemistry majors must be science students in high school, the teacher actually explains very carefully in some seemingly inconsequential places, and treats everyone as a novice.

Because both of them chose general chemistry in college, Wang Yichuan sat in front of Yang Zichen obliquely in this class, but it is impossible to know whether it was due to coincidence or careful preparation at the beginning.

"Because the solution is purified, there will be liquid heating boiling and splashing, so when heating, you must remember to add a few pieces of broken glass or zeolite to prevent boiling, so as to avoid scalding......"

"If you find that you have forgotten to add it when it is already boiling, you should move the alcohol lamp before adding ......"

Originally, there was no longer an open flame in the laboratory, and it had long since been replaced with an induction cooker. However, it is precisely because the last few small projects have more or less involved the flame color reaction, which is to use an open flame after all, so the experimental teacher simply designed all the experiments in the past few days to be operated with alcohol lamps. After all, it always doesn't hurt to learn more of these operating skills, and you can draw inferences from each other if you need them in the future.

The explanation of the safety of these experiments is a point that needs special attention, but Yang Zichen felt entangled and other feelings in his heart again because Wang Yichuan sat behind him and listened to the lecture.

Yang Zichen has always had very little experience in love, although she seems to be really super hot on the surface, but at the same time, the love stories that really appear in her real life seem to end in some unhappy situations.

In the most extreme case, the previous love between Si Li and Fang Zhihua ended in a particularly tragic ending, and there is no love but use. One person almost died, one took poison and committed suicide, and even in the end, her sister Siqing discarded what she originally loved because of her sister's death, and chose to continue to live in this world for her sister.

Although Yang Zichen was not particularly clear about the details of this matter, some rumors still reached her ears to some extent. She really has a lot of concerns about Wang Yichuan's request for this relationship, should she agree to Wang Yichuan's confession, what if everything gets worse and worse? But if you just give up, do you have to keep holding back like this?

Until now, Yang Zichen couldn't make up his mind about this matter.

The love of the poets in the ancient poems in high school seems to always be full of affection and seeing each other in silence. Dripping water sends autumn waves,

I hope you want it. Now it seems that the relationship in real life is not so simple, obviously in Yang Zichen's memory, the relationship between his parents in the early days was very good, and all the mutual consideration was reflected in his own home. Family status is equal, although it is not to the point of respecting each other, but they respect each other, and you and I come together when we encounter anything.

Thinking of this, Yang Zichen unconsciously had a smile on his face. It seems that all the entanglements just now have long been forgotten, although this is only temporary, but this short moment of a few seconds was captured by Wang Yichuan's frequent recollection. The beauty smiles, and the smile is sweeter. Wang Yichuan also smiled unconsciously.

But Yang Zichen then thought of now, the original sweet breath has long disappeared at home, and her parents' laughter is only aimed at her. When two people are alone in the same space, the atmosphere is awkward and cold. Yang Zichen couldn't figure out why it became like this. She even felt that she would be in a good mood when the two of them walked out of the house separately, and when she got home, she was in a cage. And what I said may sound good may be the existence of maintaining the relationship between the two, and the ugly thing is the shackles that bind the two.

Thinking of this, Yang Zichen didn't have any smile on his face for a long time, but frowned. And this scene was seen by Wang Yichuan again, and his eyebrows were also raised, as if he couldn't figure out what could make Zichen's mood change so much.

"Okay, students, let's do the next class, that is, the next morning, we will do the practical operation of the two experiments I just mentioned. Everyone must pay attention to safety! ”

"Alright, let's get out of class."

"Goodbye, classmates."

The teacher's words interrupted Yang Zichen's thinking about everything, and the end of class finally pulled her back to reality completely.
