super medical system

Chapter 62
"Don't think that you are not talking about yourself, I am talking about everyone! Every one of you will be killed in the future!"

The people below were silent.

"Didn't you just go through military training? Why are they all like this? Orders and orders are prohibited, do you understand?!"

"Hmph, those people in the school know how to mess around, where are the traditions of the military school going!"

As Zhong formally said, he stared at Yang Tian.

"what's your name!"

"Yang Tian."

"The first time, even if you don't know, and the next time, you will directly deduct the normal points!"

"Continue to class!"

Zhong Zhengzheng's temper was really weird and irritable. After a class, several students were punished to stand.

Yang Tian was not caught again, but he didn't listen to the class very much. He had just operated this experiment in the experimental teaching system a few hours ago, but he took a look at the ppt, and it was exactly the same as the system taught.

Since it is the same content, there is no need to waste time. Yang Tian is now thinking about how to gain experience as soon as possible.

Yesterday's random mission inspired him. It turns out that he doesn't have to treat diseases to gain experience, and the so-called "science popularization" can still be done.

However, if you want to popularize science, you must first have a deep understanding of the relevant knowledge, otherwise the system will definitely not admit it.

"Okay, that's all for now, now let's start experimenting in groups of two."

Zhong officially finished playing the last page of the ppt, and glanced at the audience.

The students in this class are really incomparable with those in the military academy before. Look at how many people were punished by themselves!And this Yang Tian in the front row!
On the surface, he was staring at his ppt, but actually he was in a daze, thinking he couldn't see it!
Those dark circles are so deep, they must have stayed up late yesterday to play games!What the hell did the Academic Affairs Office do? Didn't they tell them to cut off the Internet in the dormitories of undergraduates before? My own words are not working now?

The theory has been finished, and now it is time to start the hands-on experiment, and everyone immediately moved.

After all, it was the first time to do an experiment, and everyone was a little flustered. Zhong officially spoke a little too quickly, and he ignored some basic experimental skills because he thought they were the basics that everyone knew.

"Hey, what are we going to do first? Academician Zhong's aura is too strong. I was so busy listening to the lecture that I didn't remember..."

"Does anyone remember how to use a pipette? How to choose this range?"

"Which liquid should I get first?"

There was a mess all around, but Yang Tian and Han Bing remained calm.

"Will you do it?"

Yang Tian looked at Han Bing.

"Ah."

Han Bing nodded.

Sure enough, a good student like Han Bing would preview before class, which saved Yang Tian a lot of trouble.

"I'll get the reagents, you go prepare the equipment."

Yang Tian greeted Han Bing and walked towards the crowded podium. He should do this kind of hard work by himself.

Today's experiment is the extraction and identification of DNA, using the E. coli liquid prepared in advance.

To extract plasmid DNA from E. coli, the first step is to lyse the cell wall and membrane of E. coli to release the contents inside.

The school provided a complete set of kits, which were specially prepared by the pharmaceutical company according to the experimental requirements in consideration of the time constraints of scientific researchers. Not only did they contain prepared solutions, but they were also numbered according to the order of use.

There are two kits in a laboratory, but there are nearly 30 people, which is naturally not enough. Fortunately, most of the students are still confused and don't know what to do. Yang Tian quickly grabbed a bottle of "Solution I".

Back at the test bench, Han Bing had already adjusted the pipette, installed the disposable tip, opened the bottle, and took the liquid. The action was standardized and efficient.

Taking advantage of the opportunity, Yang Tian took the bacteria liquid with the reagents to one side. There is a vibrator here. When the power is turned on, the test tube is put up, and the vibrator will be ready in a few seconds.

Turning his head, Han Bing was already waiting to pinch his watch beside the ice water bath.

A wonderful sense of tacit understanding rose between the two. Because of the familiarity with the experimental procedures, the two didn't even need to turn over the book or read the ppt. When one was operating, the other must have prepared the equipment needed for the next step. and reagents are ready.

The chaos of the crowd was in sharp contrast to the orderliness of Han Bing and Yang Tian. Zhong Zheng was a little surprised. He glanced at it and curled his lips, but said nothing.

After 5 minutes of ice-water bathing, 200 μL of solution II was added. At this time, under the guidance of Zhong Zheng, the others gradually entered the normal state and began to add solution I.

Since Yang Tian and Han Bing's speed was about 5 minutes faster than the others from the beginning, they didn't need to make orders with others at all. They got enough ten test tubes and then proceeded to the next step together. They would always take the lead and the gap would widen. bigger and bigger.

"There is one last step."

Han Bing took out a small centrifuge tube containing the test solution from the centrifuge, and Yang Tian had already got a pipette and a clean centrifuge tube in his hands.

Carefully absorb the supernatant from Han Bing's hand avoiding the sediment below, transfer it to a clean centrifuge tube, then discard the pipette tip, Han Bing naturally reached out to take the pipette.

Touching fingertips, Yang Tian was startled.

The frost on Han Bing's face melted for a moment, and Yang Tian seemed to see her blushing, but when he looked carefully, there was nothing.

In 0.5 seconds, the fingers of the two separated instantly, and their eyes moved away.

"Ka Ka Ka, Ka Ka Ka"

The amount of liquid taken by the pipette changes with the rotation of the gears, and the hearts of boys and girls seem to have subtly changed.

Add twice the volume of absolute ethanol, put the centrifuge tube into a refrigerator with a constant temperature of minus 20 degrees, and the experiment finally came to an end.

Next, it is half an hour of waiting, and you need to wait for the DNA to precipitate.

The two sat back on the seats in front of the experimental table.

Yang Tian looked at the flustered students, with a smile on the corner of his mouth, turned his head, and a smile broke out on Han Bing's face.

Suddenly, like a night of spring breeze, thousands of trees and pear blossoms bloomed.

The hair brushed against Han Bing's ears with the breeze, and the delicate face seemed to be shrouded in a layer of light under the sunshine, and the neck was so slender and smooth.

Ripples suddenly began to appear in the lake that had not fluctuated for a long time.

There must be a reason behind the formation of a person's character. Han Bing is so good-looking when he smiles, but he has to keep a straight face every day. Why?
Yang Tian suddenly became interested in understanding Han Bing's mind.

Zhong Zhengli stood on the podium with his hands behind his back, looking down at the people in the laboratory, his eyes involuntarily fixed on Yang Tian and Han Bing.

Yang Tian looked at Han Bing silently, with a flash of light in his eyes.

"Hey!"

A scream came, and in Yang Tian's blind spot, the girl with the ponytail accidentally dropped the reagent, and the transparent liquid drew an arc in the air, heading straight for Han Bing's face.

At the critical moment, time and space changed speed again, the woman's scream was elongated in the ear, and the parabolic liquid in the air was almost stationary. Yang Tian glanced at Han Bing while stretching out his hand.

On the brown reagent bottle, it was written impressively: Chloroform!
