A month later.

Before you know it, the time has moved from late autumn to winter.

In late January, the final exams of each subject came one after another, and the campus was filled with the atmosphere of vacation, and there was a joy in suffering.

In Shangdu, dark clouds formed by cold and warm air masses covered the sky of the entire southern part of Zhongzhou, snowflakes began to appear in the Yangtze River basin, and the meteorological observatory also issued a cold wave warning.

At this time, Chen Chen, who was in the library, had just put down a copy of "Lippincott's Illustrated Reviews: Biochemistry" and exhaled deeply.

This represents the end of a month of dark study program.

Of course, this is only the first stage.

In the past month, Chen Chen has not only completed the knowledge points of several disciplines such as cell biology, microbiology, molecular biology, biochemistry, genetics, etc., but also delved into the field of stem cells and biochemistry, raised it to a master's level, and put forward several ideas.

For example: "Can the subject's nervous system be reconnected while maintaining the subject's physiology while separating the subject's head and neck, and then using autologous neural stem cell therapy?" ”

Another example: "Can the use of chemoradiotherapy to destroy senescent stem cells in the bone marrow of elderly subjects, and then use the 'homing function' to inject in vitro cultured autologous hematopoietic stem cells and mesenchymal stem cells to rebuild the immune system, can some organs of elderly subjects be rejuvenated?" ”

Another example: "Is it possible to reconstruct cranial nerves by removing part of the brain of an experimental subject and using autologous neural stem cells to create a framework model?" ”

Chen Chen feels that the branch field of adult stem cells alone has a lot to offer.

If you give yourself a lab at this time and let yourself go to do a few experiments, and then publish a few sci, you can easily start in the biological academic world, which is called lore.

But I can't.

Chen Chen thought silently, it is not realistic for him to start a project now, he is just a freshman dog, not to mention that the school cannot give himself the right to open a project topic, and even those professors' research groups will not want him.

If you can't do experiments yourself, you can't write papers, and you can't make a career in scientific research.

Chen Chen couldn't help frowning, his time was running out.

But at this moment, Chen Chen suddenly noticed that someone beside him was poking his arm with his fingers.

He remembered that the one next to him usually had some familiar faces after staying in the reading room for a long time, and the one next to him was a girl from the same Faculty of Biological Sciences, and she could often be seen reading relevant books.

However, she should be in her senior year, because she can always be seen on the computer screen frozen in the interface of her graduation project.

"Hello, I see you're reading a book on biochemistry, can I borrow a moment for you to ask a question......

The girl bit her lip with her eyes wide open, and asked with some weakness.

"Just ask." Chen Chen closed the book in his hand and looked at the other party calmly.

Facing Chen Chen's gaze, the girl unconsciously avoided Chen Chen's eyes.

As early as a week or two ago, the girl noticed Chen Chen's arrival, although the man did not have a handsome appearance, but he still attracted the attention of many people.

Not because of anything else, but because the man in front of him had an indescribable taste.

It was an aura where everything was under control, every movement, every expression, seemed so frank and swaying, extremely confident, especially his eyes, which seemed to contain a sea of stars.

Handing over the exercises in her hand, the girl carefully moved the stool to Chen Chen's side, waiting for Chen Chen's explanation from a safe distance.

There was a faint fragrance on the girl's body, it was the smell of a high-end perfume, Chen Chen subconsciously glanced at it, and then looked down at the topic.

[There is a polypeptide, its primary structure may be linear or closed-loop, please make it as simple as possible to identify, and write a detailed plan?] 】

"It's a simple question."

Chen Chen thought for a while, then said, "Use 6 moles per liter of hydrogen chloride or 4 moles of sulfuric acid per liter to reflux for 20 hours, obtain L-type amino acids without causing racemas, analyze their amino acid composition, and then select the appropriate proteolytic enzyme hydrolysis according to the amino acid composition, and try several more ......times if you are unsuccessful."

The original sample was then used as a control for polyacrylamide gel electrophoresis to separate the proteins and oligonucleotides...... You should know that next, right? ”

The girl nodded again and again, revealing a sudden look.

"Estezolam should still be eaten a little less."

Chen Chen reminded and pointed to his head, "This thing will affect your thinking." ”

"How do you know ......"

The girl was stunned when she heard this, and asked in surprise.

"Even though you cover your face with glasses, if you look closely, you can still see that your face is slightly puffy."

Chen Chen explained softly, "At the same time, your eye circles are too heavy, your eyes are bloodshot, and your skin is full of oil secretion, which are all side effects of taking estazolam, and there is this case in the book I just read." ”

"Okay, okay......"

The girl smiled awkwardly, wanting to cry without tears.

"Ahem!"

There was a cough from the front row, as if to remind them that the conversation in the library was a bit louder.

"If you can, you have to find a way to quit sleeping pills,"

Chen Chen continued, "Otherwise, you won't be able to survive the postgraduate entrance examination." ”

"You know I'm going to graduate school?" The girl was even more surprised.

"The list of students who will start the first semester of their senior year will come down, and if you succeed in your research, you won't take estazolam, and you won't ask me the question I just asked."

Chen Chen continued to explain, "Besides, a bachelor's degree in the Department of Biological Sciences is useless, at least a master's degree has a little use, and people who are a little self-motivated will choose to continue their studies, so you have only one way to go to graduate school." ”

The girl was about to cry, "It's because I'm too stupid, I can't pass the graduate school with all my hard work, and I basically smashed the ...... in the preliminary examination for the graduate school entrance examination."

"Do you want to be admitted to this school, I suggest that you find students with good grades to ask for advice, don't waste time on your graduation project, if you still can't get in...... You can wait until next year to take the test. ”

"Ahem!"

There was a heavy cough from the back row.

"But what should I do if I can't write my graduation project?"

The girl pursed her mouth and opened the conversation completely, "Also, I'm just waiting for a graduate student to show my dad, if I can't pass the exam the first time, I may not have the patience to continue the exam......"

"Just impatient?"

Chen Chen took a serious look at the girl once, the girl was not ugly, but she didn't wear makeup, and she wore a pair of black-framed glasses, which looked a little out of the ordinary.

However, if you look at her clothing brand, you won't think so.

Although the girl is wearing a dark casual dress, if you look closely, it is all Celine Hermes and the like, and even her computer is an alien brand.

Even her long satin hair is not something that ordinary shampoos can wash.

"Actually, there is still hope."

Chen Chen pondered for a while, and said again, "Students who have outstanding scientific research and academic achievements during their undergraduate years, or who have participated in large-scale discipline competitions and obtained outstanding results, can apply for academic expertise. ”

"Academic expertise?"

The girl muttered in a low voice, just raising hope, but then her face fell again, "But even if I join the mentor's project team, the project team also has outstanding scientific research results, and I can't get a ......."

Chen Chen shook his head and chuckled, "If you have enough money, you can go to the off-campus to rent a laboratory, I just have a few experiments, if it is successful, I can give you one." ”

"You?"

When the girl heard this, she showed a look of vigilance, and unconsciously moved back, "Why don't you go to the tutor if you want to do an experiment?" ”

"I haven't assigned a mentor yet."

The girl's eyes suddenly widened, and she pointed to a large pile of English materials in front of Chen Chen, "Your freshman?" ”

"Ahem!"

There was a cough on both the left and right sides at the same time.

"Class 20 of Biology 2, my name is Chen Chen."

Chen Chen took out his campus card and shook it, "Forget about the school's laboratory, the few experiments I have to do are at least in months, I am not a professor, and the school can't let me occupy it for so long." ”

"But you're only a ...... older"

The girl was a little moved, but also a little hesitant, "Are you the top student of Zhiyuan Academy?" ”

"It's not." Chen Chen shook his head.

"Then how do I trust you to help me?"

"I'm just making you an offer, and if you don't believe me, there's nothing you can do."

Chen Chen didn't care, and then turned his gaze to the book in his hand again.
