At half past six in the afternoon, the task was successfully completed.

The most difficult part of this experiment is PCR, which is much easier than extracting DNA if you don't have to do PCR.

After submitting the task, Zhou Wen did not open the box, but stood there and carefully reviewed the entire experimental process, thinking about what he did not do well enough?

After about ten minutes, he left the lab and went to the cafeteria.

In order to reward himself, Zhou Wen ordered a salted duck and a cabbage beef in the small cafeteria, accompanied by potato soup, which was called a fragrant one, and his mouth was full of oil.

Just when he was feasting, the phone rang in his pocket, and when he took it out, it was Wu Yan, who looked like a very small woman.

"Hmm...... Hello Senior Sister Wu, have you had dinner?" Zhou Wen puffed out his cheeks and politely arrived.

On the phone, Wu Yan smiled and said, "I haven't eaten yet! What, you want to invite me to eat?"

"Okay, you come to the school cafeteria, and I'll treat you to dinner. ”

"Slam the door~ In vain, I specially called you to report the news, and you want to send me away in the canteen?"

"Hehe~ There's no way, the poor jingle can only afford a small canteen. ”

"For the sake of such a pitiful person you said, forget it today, and wait for your salary next time~"

When Zhou Wen heard this, he was pleasantly surprised: "So, your leader agreed?"

Wu Yan smiled and said, "Not yet." The leader said that you are too immodest, and you will be hung for two days, I didn't see your senior sister and senior sister short, so I risked offending the leader and gave you a message, you just said how to repay me. ”

Wu Yan's words were half-true, mainly because after calming down and thinking about it carefully this afternoon, he found that Zhou Wen, a junior brother, was too calm, and he looked confident, and he was the only one.

Just like Zhang Shuguang said, you are an undergraduate student, or a biology student, and you have never published an article in a heavyweight journal, let alone a background, why are you so dragged?

Because of this, she decided to give Zhou Wen a call.

Anyway, if nothing else, Zhou Wen will definitely become her colleague, and there is nothing wrong with knowing each other a day earlier.

Zhou Wen didn't know what Wu Yan was thinking, and said with a smile: "Thank you so much~ When I pay my salary, I will definitely invite you to have a big meal." ”

"Then I'll wait. ”

The two chatted a few more words, and Zhou Wen hung up the phone.

I was in a good mood, but now I'm in a better mood.

Excited, he went to buy two cans of beer.

Snowflakes, brave the end of the world.

After drinking beer, Zhou Wen was still very restless in his heart.

He needed someone to share his feelings at the moment.

As the saying goes, wealth does not return to the hometown, just like a night walk in brocade, at this moment, parents are undoubtedly the best confidant.

And since this period of time, although there has been improvement in all aspects, the work has not been settled, and he is not embarrassed to call home more.

Downstairs in the bedroom, Zhou Wen lit a cigarette, and then dialed his mother's mobile phone.

"Hey, Mom~"

"Hey~ Is it Xiaowen?"

"Well, it's me, Mom, what are you doing?"

"At work, the machine is buzzing and I can't hear clearly~ Is there anything you have to do when you call your mother?

"It's not~" Hearing his mother's slightly tired voice, Zhou Wen's nose was sour, "Mom, tell you something, I got a job......"

Zhou Wen chatted with his mother for half an hour, and when he hung up the phone, he seemed to be able to hear his mother's happy laughter in his ears.

He also grinned so much that the corners of his mouth reached the root of his ears, and the confusion that had been stuck in his chest for a while was swept away at this time.

Back in the bedroom, no accident, only Lu Niang was left.

Zhang Wei is busy working part-time and looking for a job, Liu Yukun is busy setting up and adding pickle girls, Chen Zhiyuan has been completely salted since his work was yellow a while ago, and he stays in the Internet café every day to play games, like an Internet addicted teenager.

Lu Niang lay on her side on the bed, put her hand on her forehead, and said casually: "Someone just sent you a letter." ”

Zhou Wen, who was packing up his toiletries and preparing to go downstairs to take a bath, said strangely: "What is the letter?"

"Here!" Lu Niang reached under the pillow and took out a white envelope, and then shook it with two fingers, "Now I still use the envelope to pass the book, this woman is emotional enough~"

"How do you know it's a woman?" said Zhou Wen put down the plastic basin in his hand, walked over and took the envelope from Lu Niang's hand.

"Of course I know~ You smell the envelope, it is a blue starlight collector's model just launched by Hermes at the beginning of this year, and generally only girls like this taste. ”

Hearing Lu Niang's words, Zhou Wen subconsciously put the envelope on the tip of his nose and sniffed it.

A cool fragrance of cool tones immediately hit his nose, reminding him of a girl in a white dress on a moonlit night, looking up at the blue full moon overhead, beautiful and natural.

Zhou Wen tore open the envelope, opened it, and took out a folded note from inside, with a few words written on it: At seven o'clock tomorrow morning, the playground will not be dispersed, and the payment will be made: debt collector. ”

The deer lady who stretched her neck to look at it was curious: "Who?"

Zhou Wen looked at the words on the note, and probably guessed who it was, "Debt collector." ”

After saying that, he folded the envelope, stuffed it under his pillow, and then went to take a shower with a plastic basin.

……

The next morning, Zhou Wen arrived at the playground at half past six.

I ran for half an hour against the rising red glow, and at seven o'clock, I saw a girl in a black sportswear with long legs standing by the fence outside the playground.

Zhou Wen squinted slightly, it was like a super telescope in front of him, the picture was immediately pulled closer, and if he looked closely, it was Xu Shuangyu who was hit by him half a month ago.

Under the morning sun, some baby fat faces, as if they were smeared with a layer of red glow, look particularly delicate and moving.

"Hi...... You... Hello. Zhou Wen ran to Xu Shuangyu's side, gasped and said hello, "How is your foot injury?"

Xu Shuangyu was still a little embarrassed, but as soon as Zhou Wen mentioned the foot injury, she immediately became angry in her heart, and evil was born to the side of her guts.

"What do you say?" said Xu Shuangyu with a puffed cheek.

How does Zhou Wen know what Xu Shuangyu is angry about, in fact, he is still strange in his heart, isn't it just a bump, as for the fact that he still came to him for half a month, could it be that he can still bump into pregnancy?

"What's the matter, your feet still hurt?" As she spoke, Zhou Wen looked at her feet.

Xu Shuangyu clenched his little fist and said angrily: "What else do you say!"

Do you know how I've spent the past half a month?

I can only stay in the dormitory every day, and basically I can't go anywhere.

Three meals a day, I ask my roommate to help me bring them.

The course also pulls down a lot.

In order not to worry my mother, I can't go back to my home.

Moreover, you are obviously from the biology department, but you lied to me that you were a medical student.

Say, "What sin are you to blame?"

After listening to Xu Shuangyu's accusation, Zhou Wen finally knew what she was angry about, "Okay, it's really me wrong, I apologize to you." ”

Xu Shuangyu snorted, "I don't accept your verbal apology. ”

Zhou Wen: "Then what do you want? I don't have much money, so I can't give you financial compensation." If you don't think this will work, I'll treat you to a meal. ”

Xu Shuangyu looked at him and said, "You have no money, what are you still inviting me to eat?"

Zhou Wen said with a smile: "I can't afford a star-rated hotel, but a small hotel is still fine." I just got a job, and I'm planning to invite my roommate and fellow student to dinner tonight, do you want to come along?"

"With you inviting someone to dinner like this, I feel like I'm rubbing rice. Xu Shuangyu rolled his eyes, then turned around and said, "Let me think about it." ”

After speaking, he asked Zhou Wen for a signal, and then staggered away with his hands behind his back.

Zhou Wen bared his teeth and smiled, this girl has a small chest and a big temper.

At 9 o'clock in the morning, Zhou Wen came to the General Hospital of the First People's Hospital of Jiangzhou City.

Originally, Wu Yan told him last night that the leader was still thinking about it, but she called him again at 8 o'clock in the morning, saying that after her communication, the leader agreed to let him come for an interview today.

Standing at the door of the solemn outpatient department building, Zhou Wen had mixed feelings in his heart.

Seriously, he never dreamed that after graduating from university, he would have the opportunity to work at the First People's Hospital of Jiangzhou.

Fate is simply amazing.

After sighing for a while, Zhou Wen casually asked the family members of the patients passing by, "Where is the testing center?"

"The testing center building is in the back. ”

"Thank you~" Zhou Wen was just about to go over after thanking him, and that Senior Sister Wu Yan had already come over.

"I've been waiting for you for a long time, come with me~" Wu Yan led Zhou Wen to the testing center.

Compared with the endless flow of outpatient department building in front of it, and the noisy inpatient building, the testing center seems deserted, looking through the glass wall, the lobby on the first floor is empty, and no one can see it.

"Wow, blahh—"

The sound of crisp footsteps echoed under the eaves.

In the disinfection room at the entrance of the lobby, the two changed into lab coats, and then took the elevator to the 6th floor after disinfection.

When the elevator opened, there was neither a wall nor a department office, but a long passageway, on either side of which were rooms separated by transparent glass, and in each room there were three, five, seven, or eight researchers who were busy with their heads down.

As a rough estimate, no less than 100 people.

Zhou Wen was shocked by the scene in front of him, he knew that these were all the heroes behind the hospital, they were not as glamorous and respected as doctors, but they were silently guarding the lives of countless people......
