"hiss-"

"ah--"

“Haoshi ちいい”

After eating the apple, Zhou Wen was immediately energetic and radiant, and all his fatigue was wiped out.

He once again devoted himself to DNA extraction.

Practice makes perfect, and with continuous extraction, Zhou Wen's speed is getting faster and faster.

One DNA plant was extracted in an average of 2 hours.

When it was bright outside, Zhou Wen finally extracted all seven raw materials DNA that needed to be used.

Looking at the DNA sample in the ice box, a feeling of accomplishment surged in his heart.

The first time you extract plant DNA, you can achieve such perfection. Who else can you ask?

After a while of happiness, a faint sense of fatigue came.

From yesterday morning to now, he has been busy for 24 hours, and he has hardly stopped to rest in the middle.

Let's take a look first.

He put the DNA into a sterile box and sent it to the PCR laboratory on the fifth floor.

To prevent anyone from messing up after work, he even wrote a note on the box to inform him.

Then he took a taxi and went straight to the school.

After returning to the dormitory, my teeth were not scanned and I was washed and I was just thrusting my body.

I slept until twelve o'clock in the afternoon and opened my eyes, and there was no one in the dormitory.

I went to take a shower and was resurrected with full blood.

Then I went to the cafeteria alone for dinner.

Halfway through the meal, he suddenly remembered that the box from yesterday was not open yet.

Open the system inventory and a black treasure chest was lying quietly inside.

After clicking, the treasure chest appeared in front of me. [Will you unbox it now? Yes/No]

Zhou Wen took a deep breath, and with great expectations, he chose [Yes]

The black iron treasure chest slowly opened, and a green pampered roll appeared inside.

When Zhou Wen saw it, he was very excited. It was obvious that it was a prescription.

It's true, a prompt box pops up in front of you, [Congratulations, get the biological scar cream formula x1]

"Good things, good things~" Zhou Wen was very excited just by looking at the name.

A person will always experience some bumps and bumps from childhood to adulthood, leaving some ugly scars.

There are also scalds, scars left after surgery, etc.

According to the modern people's love of beauty, if biological scar cream can really eliminate various physical, biological and chemical scar marks, then the value of this formula is simply incalculable.

After being excited for a while, he had just planned to learn the formula, but then he thought that the rice aphid experiment needed a lot of points to speed up the experiment. At this time, he could not waste points at will.

Then I looked at the experience value, which was already 1,000, and I could upgrade my subjects.

After a glance at the subject catalog, I found that there was an extra [Botany] in the branch subject.

After taking a look, he withdrew his gaze and turned his attention to biological immunology.

This discipline is the most difficult in the entire biological sciences. It can be seen from the experience value that the starting experience value of other disciplines is more than 100 points, or even more than 200 points, but biological immunology is only 50 points.

Because there are too many intersecting and implicated disciplines, such as what groups of human cells are, how they are differentiated, what genes are regulated, the characteristics of metabolism, what changes occur after infection, what medicines should be used, and what risks are...

There are countless disciplines in biochemistry, pharmacy, virology, and oncology.

So the system introduces biological immunity: it lets you know the mystery of life!

It is conceivable how difficult this subject is?

Of course, once you master or even master immunology, you will definitely become an excellent doctor. Because you understand the principles of treatment, rather than blindly following experience.

Zhou Wen chose to upgrade immunology.

The next second, countless biological immunology knowledge, like a stream gathering towards the sea, filled his brain, and then the problems that were half-knowing became suddenly understood at this moment.

He knew how human cells differentiate and what genes they were regulated by.

We also know the characteristics of metabolism, changes after infection, and drug applications.

These have become indelible knowledge deep in his memory.

Zhou Wen was in a very comfortable mood. His knowledge of biological immunology was a supplement to biochemistry and pharmacology, which gave him a clearer understanding of biology.

Of course, there is still a distance before mastering immunology.

...

After dinner, Zhou Wen hurried to the hospital.

As soon as I arrived at the school gate, the phone rang. I took it out and saw that it was a local unfamiliar number in Jiangzhou.

"Hey, hello, who?" Zhou Wen walked towards the school gate while answering the phone.

A sweet female voice came from the phone, "I, Xu Shuangyu."

Zhou Wen: "Hey, why did you call me?"

Xu Shuangyu said unhappily: "Did you forget your eyes at home when you go out? You can't see such a big person?"

"Where?" Zhou Wen stopped and turned around and looked around. In the shade of the tree diagonally opposite, he saw Xu Shuangyu wearing a baseball cap.

Wearing a black and white striped long-sleeved shirt and straight jeans, it is refreshing and simple, exuding a fresh and natural atmosphere from the inside out, painting a beautiful picture.

Zhou Wen hung up the phone and stood there waiting for her to come.

Xu Shuangyu raised his head, and his expression clearly said, Come here!

Zhou Wen lowered his head and looked at the time of his phone.

The meaning is very clear, I am very busy, if you don’t come again, I will leave!

When a master fights, the focus is on momentum.

Obviously, Xu Shuangyu can't fight Zhou Wen without desires.

When Zhou Wen made a gesture to leave, he still came over.

Xu Shuangyu raised his head and said with a stinky face: "Will you die if you walk two steps?"

Zhou Wen smiled and said, "Since you won't die, why can't you come?"

Xu Shuangyu widened his eyes and said, "You can't see me standing in front of me with such a big man?"

Zhou Wen: "Then it's over. You're here, why am I going to do it?"

Xu Shuangyu's cheeks were shaking, and his eyes were looking back at the flowing waves, like a pretty woman in Jiangnan, but with a hint of stubborn ripples, carrying the charm of the daughter of the North.

Xu Shuangyu asked with her snow-white teeth: "You have been single for four years in college, right?"

Zhou Wen: "How can I see it?"

Xu Shuangyu: "If you have a low love quotient like you, you can find a girlfriend unless the sun comes out from the west."

Zhou Wen smiled, "You are wrong. I don't want to fall in love. It's not that I can't find a girlfriend, but that I don't want to fall in love because..."

Before he finished speaking, he turned around and left because he knew that Xu Shuangyu would follow him and listen to the reason.

As expected.

Xu Shuangyu followed and asked, "Say, why?"

“Because you can’t afford to offer.”

"whispering sound----"

Xu Shuangyu sneered disdainfully, "I am not capable, but I blame the girls for the reason. Do those boys with poor family conditions have no girlfriends? It is not necessarily true? After all, your emotional intelligence is too low, so no girl likes you."

Zhou Wen: "You are right. I have a low emotional intelligence in love. I don't like girls. OK?"

"It was."

"Then let it be, I have something to do, let's talk back~"

After saying that, Zhou Wen hurriedly left.

Xu Shuangyu looked at his back, wrinkled his nose and snorted, turning around and returning.

After walking two steps, she suddenly stopped again and looked back. Zhou Wen's figure had disappeared.

"Strange, why have you always met this wooden man recently?"

Xu Shuangyu muttered in her heart, then raised her leg and left.

After Zhou Wen arrived at the testing center, he did not delay for a minute and immediately started PCR amplification.
