"Shhhhh

"Ahh

"気持ちいい"

After eating the apple, Zhou Wen immediately felt energetic and radiant, and all his tiredness was swept away.

Once again, he threw himself into DNA extraction.

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

On average, it takes 2 hours to extract DNA from one strain.

When it was bright outside, Zhou Wen finally extracted all the 7 raw materials DNA that he needed.

Looking at the DNA sample in the ice box, he felt a sense of accomplishment in his heart.

The first time you extract plant DNA, you can do it so perfectly, who else?

After a moment of rejoicing, a faint feeling of tiredness hit.

From yesterday morning to now, he has been busy for a full 24 hours, and he has hardly stopped to rest in between.

Let's go squint for a while.

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

To prevent anyone from breaking him after work, he also wrote a note on the box to inform him.

Then I took a taxi and went straight to school.

After returning to the dormitory, I didn't brush my face or wash my teeth, and I just stood up.

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

I went to take a shower and came back to life full of blood.

Then a person goes to the cafeteria to eat.

Halfway through his meal, he suddenly remembered that yesterday's box hadn't been opened yet.

Open the system inventory, and a dark treasure chest is lying quietly inside.

clicked, and the treasure chest appeared in front of me, [May I ask if you open the box 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 parchment roll appeared inside.

When Zhou Wen saw it, his heart was suddenly excited, this look was a prescription.

Sure enough, a prompt box popped up in front of me, [Congratulations, you got the bio-type scar cream formula ×1]

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

From childhood to adulthood, a person will always experience some bumps and bumps, leaving some ugly scars.

There are also burns, scars left after surgery, and so on.

According to modern people's love of beauty, if biological scar cream can really eliminate all kinds of physical, biological, and chemical wound traces, then the value of this formula is simply immeasurable.

After being excited for a while, he was just going to learn the formula, but then he thought of the rice aphid experiment, which needed a lot of points to speed up the progress of the experiment, and he couldn't waste points casually at this time.

Then he looked at the experience points, which was already 1000, and he could upgrade his discipline.

glanced at the subject catalog, and found that there was actually one more sub-discipline [botany]

After two glances, he withdrew his gaze and turned his gaze to biological immunology.

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

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

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

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

Can you imagine 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 principle of healing, not blindly follow experience.

Zhou Wen chose upgraded immunology.

In the next second, countless biological immunology knowledge, like a stream converging towards the sea, filled his brain, and then those half-understood questions suddenly became clear at this moment.

He learned how human cells differentiate and what genes they are regulated by.

It is also known about the characteristics of metabolism, changes after infection, and drug application.

These have become indelible knowledge in his memory.

Zhou Wen was in a good mood, and the 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 long way to go before you are proficient in immunology.

......

After eating, Zhou Wen hurried to the hospital.

As soon as I arrived at the school gate, the phone rang, and when I took it out, it was an unfamiliar number in Jiangzhou.

"Hey, hello, who is it?" Zhou Wen answered the phone as he walked towards the school gate.

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

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

Xu Shuangyu said very unhappily: "Did you forget your eyes when you went out, you can't see such a big person?"

"Where?" Zhou Wen listened, stopped and turned his head to look around, but under 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-leg 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 over.

Xu Shuangyu held his head high, and his expression was clearly saying, come here!

Zhou Wen lowered his head and looked at the time on his phone,

The meaning is very clear, I'm busy, if you don't come again, I'll leave!

The master has made a move, and what he pays attention to is a momentum.

Obviously, Xu Shuangyu is nothing more than Zhou Wen, who has no desires.

When Zhou Wen was about to leave, he still came over.

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

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

Xu Shuangyu's eyes widened and said, "I'm such a big person standing in front of me, can't you see it?"

Zhou Wen: "Isn't that over, you're all here, why should I go over?"

Xu Shuangyu's cheeks trembled, and her eyes looked back at the flowing waves, like a pretty Jiangnan woman, but with a trace of stubborn ripples, with the charm of a daughter in the north.

Xu Shuangyu grinded his snow-white teeth and asked, "You have been a single dog for four years in college, right?"

Zhou Wen: "How can you see it?"

Xu Shuangyu: "With a low EQ like yours, if you can find a girlfriend, unless the sun comes out of the west." ”

Zhou Wen smiled, "You're wrong, I don't fall in love, it's not that I can't find a girlfriend, it's 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 and listen to the reason.

Sure enough, as expected.

Xu Shuangyu followed next to him and asked, "Say, because of what?"

"Because they can't afford to provide for it. ”

"Woo ————"

Xu Shuangyu let out a disdainful sneer, "I don't have the ability, but I blame the girl for the reason." Isn't it true that all those boys with poor family conditions don't have girlfriends? Not necessarily? In the final analysis, your emotional intelligence is too low, so no girl likes you. ”

Zhou Wen: "You're right, I have low EQ in love, and I don't like any girl, okay?"

"It meant to be. ”

"That's it, I still have something to do, let's talk back~"

After speaking, Zhou Wen left in a hurry.

Xu Shuangyu looked at his back, wrinkled his nose and snorted, turned around and went back the same way.

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

"Strange, why do you keep meeting this wooden man lately?"

Xu Shuangyu muttered in his heart, and then raised his legs and left.

After Zhou Wen arrived at the testing center, he didn't delay for a minute, and immediately started to do PCR amplification.

Unlike DNA extraction, PCR amplification can be done with multiple samples at the same time.

Zhou Wen prepared samples of the DNA of seven plants one by one.

After getting on the PCR machine, he was not idle, but began to configure the biological enzyme preparations that needed to be added.

This is much simpler than plant purification, and it only needs to be added in strict proportion with various biological agents.

At half past four in the afternoon, the plant DNA was amplified.

I took the samples out of the amplification instrument one by one and looked at them, and the amplification effect was very good.

Next, there are a series of complex preparation and sterilization procedures following a professional biotech pharmaceutical process.

However, Zhou Wen is a laboratory pharmacy and does not need to be marketed, so some steps are directly omitted, and some use simple procedures, such as purification and separation, concentration, crystallization, etc.

This saves him more than 90% of his time.

At three o'clock in the afternoon, the first batch of 12 biological analgesics was successfully formulated.

Then there is the final step, in vivo experiments......
