The next morning the sun was shining, and the cool breeze warmed up with the rising sun.

On the boulevard of the campus, there are couples strolling, grinding and whispering all the way, exuding the atmosphere of "spring".

The single dog mixed in with it, his face is impassive, but his eyes are full of envy, jealousy and hatred - you will not end well!

Zhou Wen, who was wearing a biological mask, came all the way to the experimental building.

Originally, he planned to go to the library today to hang up, but he was still a little worried that the mutant aphid yesterday would carry the virus, so he decided to come over for an electron microscope observation and then do a blood test by the way.

When I was changing into a lab coat in the locker room, I accidentally opened my eyes and saw that the clothes were crawling with bacteria, especially the cuffs and neckline, which were simply dense.

And when he took the clothes, the germs also got on his hands.

"it-" Zhou Wen threw away his lab coat with a spirit in his hand.

Then he quickly put away his true eye.

Although I know that these bacteria are symbiotic with the human body and there is no harm, it is really unappetizing to watch them crawl around on my body.

Zhou Wen warned himself in his heart that he couldn't just open his eyes in the future, otherwise he wouldn't be able to live his life.

But the lab coat on the ground can't be wanted, I don't know that there are countless bacteria on it, and if I know it, I can't get past my psychological level.

Fortunately, there is also a spare suit, which has just been washed for a few days, and I am about to change it.

This time, he learned to be obedient, and he didn't dare to see how many bacteria were on the washed and dried lab coat? After changing it, he went straight to the laboratory.

Out of sight, out of mind.

When I got to the lab, I took my temperature first.

Body surface: 36.5°C.

Oral: 37.1 degrees Celsius.

Normal.

Next, start the sterilization of the experimental utensils.

It's the first thing you do when you enter the lab every day.

After working for more than an hour, I finally put the experimental utensils that needed to be sterilized at high temperature into the sterilization pot, and it was at this time that Shi Lei came.

Seeing that Zhou Wen was also there, he said strangely: "Hey, why are you here today?"

Zhou Wen said with a smile: "I didn't do the experiment yesterday, and I felt uneasy when I went back, so I came over today to make up for it." ”

Zhou Wen didn't wait for him to continue asking, and said with a smile: "How was yesterday, where has it been?"

Shi Lei smiled innocently and didn't speak.

Gossip is a common feature of human beings, and Zhou Wen is no exception, seeing that Shi Lei refused to say, he asked tentatively: "The blind man touches the elephant?" or ...... Intubated?"

Under the indiscriminate bombardment of those sluts in the dormitory, although Zhou Wen is still physically pure, his mind has been completely polluted, and he speaks in a riot.

Shi Lei said embarrassedly: "No." Lan Lan has a very shy personality, not as exaggerated as you said. We just watched a movie and had dinner by the way. Still...... I also kissed it. ”

"I'm sorry ~ just kiss you, what's so embarrassing?"

Zhou Wen was speechless, "Shy senior girl...... You believe it. So you're going to send them back after dinner?"

Shi Lei nodded, "Hmm~"

Zhou Wen: "...... Since people are willing to go to the movies with you, they must have brought their ID cards, and you actually sent them back. ”

Shi Lei was puzzled: "Why do you have to bring your ID card to watch a movie?"

Zhou Wen: "............ Movie theaters sometimes check ID cards. ”

"Oh~" Shi Lei rarely goes to the movies, and he doesn't understand much, so he thinks what Zhou Wen said is true.

Shi Lei smiled and went to check the DNA of the white rats in the sterile box, and then said strangely: "Hey, you made 8 strains?"

Although a mouse can theoretically extract 4~8 strains of DNA, it is usually 4 strains, and it is easy to cause DNA extraction failure if there are more, so Shi Lei was a little surprised.

Zhou Wen said casually: "Yes, I was bored yesterday and did a few more sets of experiments." ”

Shi Lei looked through the glass window at the white mouse cage in the next room, and the white mouse in one of the cages was empty, "The electron microscope observation you did?"

Zhou Wen said "um", "I always fail." ”

Shi Lei nodded in understanding. For example, when undergraduates just start to do DNA extraction from mice, the failure rate is very high, especially for electron microscopy observation, temperature, time, and technique, which will greatly affect the success rate.

Shi Lei sealed the DNA box and said, "I'm going to deliver it." Wait for Lin Jiayi to come, you let her make 6 more plants. ”

Zhou Wen nodded, "Well, I know~"

At ten o'clock, Lin Jiayi came.

It was at this time that the sterilization was completed.

Seeing that Zhou Wen was also there, Lin Jiayi showed surprise on her face, walked over and said angrily: "Zhou Wen, discuss something with you~"

Zhou Wen took out the corpse of the mutant aphid that was frozen yesterday from the cryogenic freezer, and said as he walked, "Do you want me to help you work?"

"Shi Lei told you?" Lin Jiayi grinned, "I have something to do today, and I don't have time to do it, please." ”

Zhou Wen: "Why are you going on a date with your boyfriend?"

Lin Jiayi bit her lip and pretended to be pitiful and said, "That's right." Isn't it good~"

As soon as Zhou Wen heard this, he immediately planned to refuse.

She and her boyfriend spent the moon and Han Ting like home, and they helped her do experiments by themselves, and she had a brain disease!

At this moment, a "ding" sound sounded in my ears, followed by a pleasant and soft prompt sound like when I completed the task last night, [Ding! from Lin Jiayi's request, do you accept it?]

Zhou Wen summoned the system, and a prompt box popped up in front of him.

[Task: Help Lin Jiayi complete the DNA extraction of 6 white rats.]

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

Do you accept it?】

Zhou Wen saw the reward, and was a little strange, "Hey, isn't this task exactly the same as yesterday, why have the rewards and points increased?" Could it be ...... What is the difference between active and passive?"

Yesterday was a mission that was actively released by the system, so the experience point is relatively low?

And today is a task that he passively triggers, so the experience given by the system is high?

Zhou Wen thought to himself: "Could this be a bug? If I take the initiative to trigger the task, will the system score be high?" ”

Lin Jiayi saw that Zhou Wen had no sound for a long time, and said in a loud voice: "Zhou Wen~~~ is it good~~"

Zhou Wen came back to his senses and said with a look of "reluctance": "Okay...... bar. ”

"Thank you Zhou Wen~" Lin Jiayi jumped up happily, eager to give a fragrant kiss to Zhou Wen as a reward.

Of course, that's not possible.

After verbally thanking her, Lin Jiayi ran away with a "bang".

Here, Zhou Wen discarded the picture of Lin Jiayi applauding her boyfriend for love at night in his mind, and concentrated on the virus test.

Remove the mutant aphid carcass from the ultra-low temperature freezer, grind and crush, extract and centrifuge.

A total of 4 samples, after the True Eye scanned them one by one, nothing unusual was found.

However, he was not at ease, so he prepared two samples for electrophoresis analysis at the same time, and two samples for electron microscopy observation.

At this time, Shi Lei packed lunch and came over.

"Came out to eat...... Hey, where's Lin Jiayi?"

"I went on a date with my boyfriend. ”

"Her own work, why do she keep dumping it to you. ”

"It's okay, I'm idle anyway......"

The two men walked out of the lab as they spoke.

After washing his hands in the sink at the door, and sitting down in the office opposite the door, Shi Lei opened the three or four vegetable boxes packed one by one, including scrambled eggs with tomatoes, fried meat, fish heads with chopped peppers and a corn rib soup.

Zhou Wen looked at it and said, "Hey, it's so rich, have you picked up the money?"

Shi Lei smiled and said, "Yesterday you helped with the experiment, and today I specially treated you." ”

"Why are you so polite. Zhou Wen said, picking up the chopsticks and pulling up the rice.

After Shi Lei ate for a while, he asked, "What are your plans after graduation?"

Zhou Wen smiled: "I don't know for the time being." What about you?"

"Me...... My boss recommended me a biopharmaceutical company from China Shipping, but I haven't received an offer from the other party. ”

Shi Lei sighed after speaking, and said: "But even if you are admitted, it is not interesting, there is a senior over there, he told me that after paying five insurances and one housing fund, it will be 4,000 yuan a month." ”

"The magic capital is about 4,000 yuan......" Zhou Wen didn't know what to say for a while.

If it weren't for the pharmacist system, he estimated that he would be like Shi Lei now, worried about the future.

After eating, Zhou Wen plunged into the laboratory again......
