"Huh? When did the teacher say that, why don't I know, it's over, it's almost the end of class, and I haven't memorized it at all? Xu Yan said.

"'Walk one hundred and twenty steps west from the hillock, separate the bamboo, smell the sound of water, like a ring, and be happy.' Happy fart,, how can I memorize this, it's still classical Chinese, I haven't read it well. Seeming to be a little irritable, Xu Yan grabbed his hair with both hands, and then said with some self-deprecation, "Forget it, I can't finish it anyway, let's talk about it later." Then, lying on the table boredly playing with the pen in his hand.

Wang Xiaoshan retracted her gaze, and when she saw a familiar expression on his face, the apprehension in her heart disappeared. Turning around, she whispered the book 'like a ring, happy heart', no matter what others do, anyway, her heart is relaxed at the moment.

As if she had been poisoned by ecstasy, Wang Xiaoshan had long been unable to hear the discussion between He Wen and Zhou Ying, her eyes were now full, her heart was full, and she was thinking about that person, the person who always appeared in her sight when she was embarrassed, and then, seeing his figure, she seemed to have become more courageous, at least, not so flustered.

Just like at this moment, she was as she was at that time, quiet, not worrying about these and those things.

"Xiaoshan, did your teacher ask you to enter the laboratory so early?" Bai Minmin asked.

At this time, towards the end of the semester, almost all the courses of their graduate students were completed, and the only remaining courses were laboratory courses. After the class, there will naturally be more time. However, if you think it's easy to finish the class, you're wrong!

For their majors, the first semester of graduate school can be regarded as the easiest time for them in the past three years. Once it's over, it's unexpected, for the next two and a half years, you have to go to the lab every day to do your own experiments, to do the teacher's experiments.

Once you start experimenting, it's not just a matter of working from 9 to 5, sometimes it's possible to go back to 11 or 2 p.m. to get back to the dorm room, and then come to the lab the next day at the same time. Day after day, year after year.

However, this is far from the most exaggerated time Wang Xiaoshan has heard, according to the senior brothers and sisters in the laboratory, some other laboratories have people who do not return to the dormitory all night, just because the experiment has to last for 24 hours.

Even with these efforts, it is very likely that this experiment will not get the results you want.

Of course, now, it's just getting started, and at least in this semester, which is less than a month left, they don't need to think about these things.

"Yes, the teacher asked" Wang Xiaoshan said a little deflated, she originally thought that after class, she could still go out with her classmates, but now it's okay, and she can't go anywhere.

"We're almost there, although the teacher didn't let us go to the lab, but also let us read the literature and write a review, I heard that if we can't finish writing, the teacher won't let us go home?" He Wen didn't know where to come from.

"By the way, do you know when we're going to have a holiday?" Bai Minmin asked.

"I heard from my senior brother, the situation in each laboratory is different, it is all stipulated by the teacher, we should be a week later than the undergraduates, that is, more than 20 January, what about you?" Wang Xiaoshan asked.

"I don't know, the teacher didn't say" Bai Minmin really didn't know, the teacher she chose was really busy every day, and the most important thing was that the teacher was a little serious, and they didn't dare to ask. However, listening to the senior brothers and sisters, it is very late.

"I don't know, anyway, we can't leave until we finish our papers." He Wen looked at the two of them and spread his hands.

Alas, whether you enter the laboratory or not, everyone's pressure is not small!

Wang Xiaoshan lay on the bed and silently lamented for himself: I have to get up early every day in the future, and I have to do experiments every day in the future, and in the future, how many hairs will I have left!

The next day, early in the morning, Wang Xiaoshan got up, packed up his things, made an appointment with his friends in the same laboratory, and walked to the laboratory together.

As a result, Bai was worried all night, and on this day, they didn't do anything, just sat in their places and read the literature. Then the two had dinner together and went back to the dormitory.

The next few days seemed to be such a leisurely life, and the heart that was still a little nervous suddenly quieted down.

Just when Wang Xiaoshan thought that she could stay so leisurely until the holiday, unexpected things happened again.

"Tell me, tomorrow, three of us are going to help another teacher do a day's experiment" The senior brother in the laboratory spoke, pointing at Wang Xiaoshan, and then at Lin Lin.

"Senior brother, what experiments are we going to do tomorrow," Wang Xiaoshan asked.

"Mouse experiments, mainly because there are too many mice, and these experiments have to be done as soon as possible, so let's pass." Senior Brother patiently explained.

Speaking of which, there is one more thing that has to be said. Two weeks ago, Wang Xiaoshan had finished a month-long period with mice. It was their teacher's experiment, and there were not enough people, so that Wang Xiaoshan and Lin Lin had to go to the animal room every time they didn't have classes to do experiments.

In fact, this experiment is quite simple, that is, the mice are given different concentrations of drugs every day, filled with 30 days, and then the mice are sacrificed, the internal organs are taken, and after treatment, they are tested.

In this animal experiment, gavage is the simplest, but for those who have not been in contact with it, such as Wang Xiaoshan, it is fatal.

Wang Xiaoshan still remembers the first time she went, it was with a senior sister, before entering, Wang Xiaoshan didn't feel anything, after all, he was such a big one, and the mouse was a small one, so there was no need to be afraid.

After entering, one cage after another, looking at the mice in the cage, it was quite cute. Wang Xiaoshan stood by and watched her sister's movements and thought, it's quite simple, grab it, insert the gavage needle into it, and it's okay.

"It's easy, you can try it," the senior sister said, leaving the last mouse in the cage.

Wang Xiaoshan looked at the mouse lying on his stomach in the cage, and according to the point that his senior sister said, he went to grab the tail of the mouse first, but it was obviously a very simple action, but Wang Xiaoshan couldn't do anything. Especially when she saw that the tail of the mouse was red, it looked a little weird inexplicably.

raised his head and looked at his senior sister, a little embarrassed, this can't help but learn, maybe I will do it myself in the future.

Hard-headed, Wang Xiaoshan stretched out his hand again, but the mouse that was obediently lying on his stomach suddenly jumped up, and then quickly fled around the cage.

Wang Xiaoshan hurriedly withdrew his hand, his heart palpitated, what if it bit himself, how much it hurts, do you still need to get an injection!

The senior sister smiled, and then said, "It's okay, it doesn't bite, when we first learned, we didn't dare to catch it, and it will be fine if we catch it a few more times."

Suddenly, Wang Xiaoshan's confidence increased greatly, and the most important thing was that this little thing didn't bite people.

Stretching out his hand again, Wang Xiaoshan took advantage of the mouse's inattention, grabbed its tail quickly, lifted it to the iron cage rack, and put it away.

Don't look at Wang Xiaoshan who is quite bold this time, in fact, her heart has long been so panicked that she can't breathe. In particular, the three fingers pinching the tail of the mouse are very clear to the touch. It looks like the tail seems to be very soft, but pinched in his hand, Wang Xiaoshan feels that the tail is a little hard, especially when the mouse climbs forward, the tail feels even more weird, as if there is a force, flowing on the tail.

Wang Xiaoshan tried to suppress the illusion of grabbing a snake, and then tried to pinch the skin of the mouse's neck with his free left hand to fix the mouse's neck.

Wang Xiaoshan also doesn't remember how many times she tried that day, she only remembers that when she successfully gavaged the mice, she felt like she had been on a long march of 20,000 miles, prostration, except for prostration.

Fortunately, there are one and two, the first time has passed, and the rest is not so difficult. In this way, Wang Xiaoshan spent the next time in class, while reviewing, and at the same time giving gavage to the mice. Before entering the exam, the time was pressing, and Wang Xiaoshan's technique of gavage became more and more proficient.

In short, by now, Wang Xiaoshan is also a skilled worker.

The next day, the three of them arrived at the animal house as agreed. It's just a day, not to mention the work that you have done yourself, and it's nothing rare. It's just that there is a person who appeared to her a little surprised.

"Zhang Nan?" Wang Xiaoshan never expected that she would be here when she saw Zhang Nan again.

"Call Senior Brother," Zhang Nan said unceremoniously.

"Call" fart brother, Wang Xiaoshan wisely closed her mouth, and then stopped talking, after all, in front of so many people, not to mention the senior brother in her own laboratory, she couldn't burst into foul language, and decisively chose to shut up and not speak.

However, she did not speak, but someone did. "Senior brother" Lin Lin called.

Wang Xiaoshan glanced at Lin Lin as if unintentionally, and then whispered "Senior Brother". This senior brother called, it was a gritted teeth, she couldn't wait to go up and walk this person with two punches, but now she wants to call someone else's senior brother, she is really angry with her.

"Hey~ Don't worry, junior sister, don't worry, today's experiment is very simple, just a larger amount" Whether the sentence 'hey' is in response to Wang Xiaoshan, or just a tone word, I'm afraid only Zhang Nan himself knows.

It's not right, there is another person who also knows, that is Wang Xiaoshan, this is not difficult for Wang Xiaoshan to guess at all, that person just looked at himself and said.

"Senior sister, I don't know if you have done mouse experiments, but don't worry, mice are very docile" Zhang Nan said to Wang Xiaoshan as he walked.

"I'm not worried" Wang Xiaoshan wasn't worried at all, she just didn't want to see this person. Originally, he had quietly walked to the back, but this person actually followed her at the back, couldn't he see that she didn't want to communicate with him?

"It's good not to worry, senior brother is afraid that you will cry out in fear," Zhang Nan said a little provocatively.

However, Wang Xiaoshan didn't want to pay attention to him, rolled his eyes widely, and distanced himself from him. It's not up to him to cry or not, even when she caught the mouse for the first time, she didn't cry, how could she cry now! If you want to see her shed tears, it will be a hundred and eighty years early!
