Previously, limited to poor English proficiency, Zhou Wen could only watch Chinese teaching videos within the wall.

But now there is no need, such as BioInteractive, a well-known foreign biology video website, and PBS Learning Media, there are a large number of biology-related videos, videos and lectures, and he just goes over the wall to watch it.

After discovering the benefits of upgrading subject knowledge, for the next period of time, Zhou Wen went out early and returned late every day, and soaked in the library.

Steady growth in subject experience and credits.

During this time, he also discovered that if the boxes were not opened, they would accumulate until the next day, become two boxes, and so on.

Don't worry about not opening the box, it will be swallowed by the system.

In this way, you can open two boxes at once, three boxes, and double and double the happiness.

Zhou Wen stayed in the library for ten days, submitted five missions, and reached 1280 experience points.

I opened two boxes before, one with an empty box, and one with 100 yuan.

For the remaining three unpacking opportunities, Zhou Wen plans to save again.

Anyway, he plans to stay in the library for the next few years to brush up on experience.

Ten days ago, he had a hard time watching English videos, so he rarely went over the wall, but now he is familiar with English and finds that foreign biology lectures and videos are really very interesting.

In particular, the lectures were a combination of theory and practice, which was very vivid, which benefited him a lot and greatly broadened his horizons.

For example, PCR experiments, although he has not done it himself so far, he is clear about all the processes, techniques and precautions, and only practice remains.

On April 9, at nine o'clock in the morning on Monday, Zhou Wen received a call from Shi Lei and asked him to come over for a favor.

Zhou Wen looked at the progress of the task, there were still 10 hours left.

Got up and put the book back on the shelf, then rushed to the lab with his belongings.

When he arrived at the laboratory, Shi Lei was dissecting the white mice, while Lin Jiayi next door was watching a TV series with his mobile phone.

In addition, Yang Yudong and Gu Hongyun were also in the PCR laboratory, chatting and laughing. The two are a couple.

"What's the matter, boss?" Zhou Wen asked.

Shi Lei said: "Just now, a pharmaceutical company in Jiangzhou City called me and asked me to come for an interview, so I want to ask you for a favor." ”

As soon as Shi Lei finished speaking, a prompt sounded in Zhou Wen's ears, [Ding! From Shi Lei's request, do you accept it?]

Zhou Wen didn't look at the task panel, and said directly: "DNA extraction, no problem." ”

"Then thank you, I'll invite you to dinner when I come back. ”

Shi Lei thanked him, then asked with a smile: "By the way, the last time the testing center reported that the concentration of DNA you extracted was much higher than that of ours, how did you do it?"

"Hehe, just do what you taught me. Maybe it's a coincidence~" Zhou Wen said with a smile, waved his hand and said, "Okay, you go first, let's talk later, don't let people wait in a hurry." ”

"Well, then I'm leaving~" Shi Lei said and hurriedly left the laboratory.

Zhou Wen only opened the task panel at this time, and a task prompt box popped up in front of him.

[Task: Help Shi Lei complete the extraction of DNA from 9 white mice.]

Rewards: 200 subject experience, 300 points, and one chance to open a box (wood).

Do you accept it?】

Seeing that the reward was 200 points, Zhou Wen said secretly: "Active and passive, there is really a difference." ”

At this moment, Lin Jiayi raised her head and asked, "Hey, why did he leave?"

"Something's gone. Zhou Wen replied casually, and after choosing to accept the task, he continued to do Shi Lei's work.

Lin Jiayi grinned and asked, "Hey Zhouwen, what are you doing all this time?"

"I want to think about the topic of my dissertation. ”

Lin Jiayi let out an "oh", then stretched out her head and gossiped and asked, "I heard Shi Lei say that you saved people in the night market, right?"

"Hmm!"

"You really have to give that old man artificial respiration?"

"Hmm!"

"Huh~ It's disgusting. Seeing Zhou Wen nodding, Lin Jiayi shook her body and showed a disgusted expression.

Zhou Wen, who was staring at the centrifuge, looked up and said in amazement, "What did you say?"

Lin Jiayi still said with a disgusted face: "Aren't you disgusting to give an old man mouth-to-mouth artificial respiration?"

Zhou Wen looked at Lin Jiayi, saw that she didn't look like she was joking, and said, "If that person is your parents, do you think I won't save them because I'm disgusting?"

“.........”

Lin Jiayi was speechless by Zhou Wenyi, her face was blue and white for a while, as if she had opened a dyeing workshop.

Finally, Tie turned around with a blushing face.

Zhou Wen smiled and didn't care.

Since entering this laboratory, Lin Jiayi, the titular "senior sister", has never helped him, but he, as a novice, often has to work for her.

And never knew gratitude, as if it were taken for granted.

Just like the last time he helped her with DNA extraction, he didn't say thank you afterwards.

On the contrary, he often teased him and showed his superiority.

This kind of selfish and self-feeling girl, he is really too lazy to deal with it, and he is just clean when he doesn't speak.

After cleaning the leg bones of the rats, he began to extract bone marrow.

With the True Eye, extracting mouse DNA is a piece of cake.

After the supernatant is extracted, the next step is electron microscopy.

Just as he was walking towards the electron microscope with the slide, Lin Jiayi suddenly walked over and said coldly, "Who allowed you to electron an electron microscope?"

Zhou Wen said with a smile: "Do I still need your approval for the electron microscope?"

Lin Jiayi stiffened her neck and said loudly: "I don't need my approval." However, there are regulations in the laboratory that undergraduates are not allowed to operate the electron microscope. ”

"Then you can talk to the professor~"

"I don't say it's my business, you don't allow it anyway. ”

Zhou Wen's face slowly darkened, he had been putting up with this woman for a long time.

Just when the two of them were tense, the door of the PCR laboratory opened, and Yang Yudong and Gu Hongyun came out.

Gu Hongyun said, "Why are you two blowing your beards and staring?"

Lin Jiayi, who was originally cold, had miraculously red eye circles, didn't say a word, walked to the side, and cried on the table.

Gu Hongyun looked at it and said, "Zhou Wen, are you bullying Jiayi?"

Zhou Wen said expressionlessly: "I bullied her, do you think she is a master who will be bullied?"

Gu Hongyun blinked his eyes and pretended to scold: "You still say~"

Yang Yudong also came over and grabbed his arm and pulled him aside. "Okay, okay, Zhou Wen, you don't have to say a few words. People who are about to graduate, what are you doing~"

Over there, Gu Hongyun began to comfort Lin Jiayi, "Don't cry Jiayi, it's all Zhou Wen's fault, I'll help you scold him later...... Let's go to dinner first. ”

Gu Hongyun pulled Lin Jiayi, who was rippling with tears, and left.

Yang Yudong also pulled Zhou Wen and said, "Let's go, let's go eat together." ”

"Wait a minute, it'll be right away~" Zhou Wen picked up the slide and put it on the stage.

Yang Yudong stood next to him and said with a smile: "Only villains and women are difficult to raise." Be generous, don't be angry with her~"

Zhou Wen said while adjusting the electron microscope multiple: "This woman can't talk with her brain, I scolded her, and she began to cry and make trouble with me...... Forget it, don't bother to talk about her. ”

Yang Yudong just wanted to enlighten him, but suddenly found that Zhou Wen was observing DNA with an electron microscope, and said in surprise: "Hey, you can do electron microscopy observation?"

"Hmm!"

"When did you learn it, I'll see~"

Yang Yudong squeezed Zhou Wen aside and stared at the camera, and the DNA strand inside was clear......
