"What's the matter? Do you want to go back to reading books and prepare for the graduate school entrance examination?"

"No, we still have an experimental class this semester, and the experimental teacher asked me to help me go to the sheep ranch in the northern suburbs to buy a few sheep and come back for experiments. Pen, fun, pavilion www. biquge。 info”

You Kexin: "The sheep ranch in the northern suburbs is quite far away, and it takes an hour to drive, in the past, the sheep we needed in the experimental classes of our undergraduate years were bought from the sheep pasture in the northern suburbs, but these things are done by the school logistics department, why, this year you students want to go in person?"

You Kexin graduated from the School of Animal Science of Shida University and was admitted to the School of Biological Sciences, Ye Zhenzhen was admitted to the graduate school of the School of Biological Sciences from the Department of Basic Medical Sciences, and Zhang Zhongsheng was an undergraduate student of the School of Biological Sciences.

Zhang Zhongsheng: "The first few times the sheep bought by the school logistics department are not in very good condition, the experimental teacher has to personally select this time, but our experimental teacher is a young teacher who has just graduated, or a woman, I heard that the rancher of the sheep ranch is not very good to talk, I think, this time to pull me over, is to be courageous." ”

Zhang Zhongsheng looks like a typical northerner, burly, standing beside him, he is indeed very secure, You Kexin quipped: "Zhongsheng looks quite safe, did you drive there by yourself?"

"No, the school logistics department has a car to go to the sheep ranch, and we will take that car together. ”

Ye Zhenzhen: "The sheep ranch in the northern suburbs is a famous scenic spot in our S city, you can take a break by the way, and when you come back, if you have time, you can come to our laboratory again." ”

Ye Zhenzhen followed You Kexin to the P2 laboratory in the laboratory, and Zhang Zhongsheng left after preparing the reagents.

Ye Zhenzhen's master's project is about the protein expression of a bacterium, and Ye Zhenzhen's topic is about the protein expression of viruses, whether it is a bacteria or a virus, the difference is only the size of the protein, but the first few steps of the experiment are infectious, so they have to work in the P2 laboratory.

A busy day passed quickly, and Ye Zhenzhen was busy discussing the difficulties of the project with You Kexin, and at the same time busy continuing her master's extension project.

Unconsciously, Ye Zhenzhen's campus life at Shi University passed another week, and You Kexin's master's project had made a breakthrough, You Kexin was happy, and invited Ye Zhenzhen to the restaurant next to the school to have a big meal, shabu mutton hot pot, the two chatted while eating, You Kexin was very interested in Ye Zhenzhen's trip to Paris, Ye Zhenzhen roughly said the experiment done in Pasteur, just bypassing the unknown package incident and Nan Zhiqiao, Ye Zhenzhen has turned that incident and that person into the secret of her heart.

――

Zhang Zhongsheng did not go to Professor Zhang's laboratory for many days, and it has been more than a week since he reappeared.

On Sunday afternoon, Zhang Zhongsheng brought a pair of blue disposable masks and appeared in Professor Zhang's laboratory, because it was Sunday, there were not many people in the laboratory, only Ye Zhenzhen and You Kexin in the huge laboratory, the two saw Zhang Zhongsheng, they were stunned, Ye Zhenzhen first asked: "Zhongsheng, what's wrong? Why are you wearing a mask?"

Zhang Zhongsheng sneezed unconsciously, and replied in a hoarse voice: "I have caught a cold in the past two days, and I am afraid of infecting you, so I wear a mask." ”

Ye Zhenzhen: "It's the time for the autumn and winter seasons, it's cool in the morning and evening, and it's easy to catch a cold." ”

You Kexin: "Zhongsheng, I see that you have always been in good health, why did you suddenly catch a cold?"

Zhang Zhongsheng looked helpless, "I think I was infected." ”

"Why do you say that?"

Zhang Zhongsheng: "Several people in our class have caught a cold, by the way, and Teacher Xiao Chen, who led our experimental class, also has a cold, Sister Zhenzhen, is it an epidemic now." ”

"Perhaps, this season is already prone to flu outbreaks, you go back and take some antiviral cold medicine, it should be fine soon. ”

Zhang Zhongsheng shook his head with a smile, "No, I'm in good health, the anti-primary antibody will pass, if you have a cold, take medicine for two weeks, don't take medicine, fourteen days, it's the same." ”

Ye Zhenzhen reminded: "A cold can heal itself, but I am afraid of causing other complications, Zhongsheng, you should pay attention to yourself, if you feel uncomfortable, you must go to the hospital as soon as possible." ”

"Well, Sister Zhenzhen, I'll pay attention. ”

You Kexin also comforted: "Since you have a cold, don't come to the laboratory, go back to the dormitory to rest." ”

"No, I came to see Sister Kexin to do experiments, I heard Sister Zhen Zhen say that your master's project has made a breakthrough, so come and have a good time and study." ”

You Kexin: "Unfortunately, today's experiment has just been completed, and the next experiment will wait until two days later, so you can come back on Tuesday." ”

Zhang Zhongsheng had a very regretful expression, "I missed it again, you must call me next time." ”

"Well, I'll call you on Tuesday to inform you, or I'll show you today's experimental procedures, which can be regarded as increasing theoretical knowledge. You Kexin was happy because of the breakthrough progress of the subject, and generously took photos of the experimental records of the past few days and sent them to Zhongsheng, and at the end of the special instructions, "These contents can only be read by yourself, and cannot be passed on, this is the confidential content of my master's thesis, and it cannot be leaked before my thesis is published." ”

Zhang Zhongsheng swore in a sworn tone, "Sister Kexin, don't worry, what the master has taught will never be passed on." ”

As soon as he finished speaking, Zhang Zhongsheng sneezed twice in a row, and beads of sweat oozed out of his head, looking like he had a very serious cold, You Kexin urged: "The cold is so serious, go back to the dormitory to rest." ”

Zhang Zhongsheng nodded cohesively, and then asked Ye Zhenzhen, "Sister Zhenzhen, do you have any experiments to do?"

Ye Zhenzhen shook her head, and was just about to speak, when the mobile phone in her pocket rang, and she took the phone, it was the courier brother.

You Kexin asked casually, "Zhenzhen, did you buy something online?"

"Well, I bought the book. ”

"I'm about to graduate, what books are you going to buy?"

"The book for the job. ”

As soon as they heard that it was about applying for a job, You Kexin and Zhang Zhongsheng came to the spirit again, and they had to see what kind of book it was.

Within five minutes, the courier brother sent the package into the laboratory, and after Ye Zhenzhen signed for it, she opened the package and saw that it was a blue hardcover book, titled "Response and Disposal of Bioterror".

When You Kexin and Zhang Zhongsheng saw the title of the book, their eyes widened and they exclaimed, "You are reading this kind of book, so professional." ”

Ye Zhenzhen: "Someone recommended that you want to work in the disease control system, and you need to know more about this aspect. ”

You Kexin asked: "Who recommended it, so professional!"

Ye Zhenzhen thought of Nan Zhiqiao and smiled slightly, "A friend who works in the disease control system." ”
