The difference between cloud and mud

The dragging made Jiang Tong catch up with the evening rush hour of urban traffic.He ran wildly after getting out of the car, and was still late, making his experimental partner wait for half an hour.

This is a postgraduate course, and Jiang Tong begged the professor to register and became the youngest face in the class.The student who cooperated with him was a first-year doctoral student. When he got the results of the group, he was full of disapproval, thinking that Jiang Tong was overthinking his abilities and would definitely hold him back.

Aspiring is not at a young age.Jiang Tong spent the most time on this course, and he also took a breath, trying to get rid of the doctor's prejudice.However, the moment he opened the door panting, Jiang Tong saw the cold impatience in the doctor's narrow iron gray eyes, and Jiang Tong knew that his efforts were in vain.

The doctor is of Chinese-European mixed race, taller than the average Asian, and his profound facial features are tense under the lights of the laboratory's fiasco, revealing a harsh and oppressive handsomeness.

"Brother Pei, I'm sorry." Jiang Tong hurriedly put on a white coat: "Some private matters have been delayed."

"Don't talk." Pei Jing said impatiently.He is concentrating on operating the pipette to transfer the DNA sample, and if he is distracted, all previous efforts will be wasted.Jiang Tong didn't dare to disturb him, so he turned around twice, and then went to check the settings of the PCR instrument to prepare for heating.

According to the division of labor beforehand, Jiang Tong prepared the DNA samples and reagents, and Pei Jing was responsible for adding the samples.Jiang Tong was absent for no reason, and Pei Jing took on the work of the two alone, and the progress did not drop at all.

The operation of PCR and sample analysis is also mainly performed by Pei Jing, with Jiang Tong assisting.Every movement of Pei Jing is like a copy of a textbook, efficient and precise like a robot.Except for the necessary communication, Pei Jing didn't say a word the whole time, and the whole body exuded a thick low air pressure, and the five characters "I'm not happy" were almost carved on his face.

The two finished the experiment without saying a word, and it was already late at night.Thankfully, the quality of the data is not bad, Jiang Tong's heart hanging in mid-air slowly landed.

He breathed a sigh of relief, wanting to apologize again to Pei Jing, but the man took his coat and walked out the door, as if he was reluctant to even be in the same room with him.

"Brother Pei" Jiang Tong chased out the door quickly: "Brother Pei, I'm really sorry this time. I can guarantee that similar things will not happen again."

Pei Jing stopped in her tracks: "Jiang Tong, how much do you love money?"

Jiang Tong was taken aback: "What?"

Pei Jing sneered: "Thesis writing, restaurant kitchen, tutor... How many part-time jobs have you found?"

"You are studying through the government-funded study abroad program. Isn't the scholarship enough to live? If I remember correctly, it is a lot of money."

Jiang Tong's voice tightened: "Pei Jing, you must speak with evidence."

Pei Jing looked cold: "If you only want to make money, don't do scientific research. Please leave resources to those who really have ideals."

"When Professor Gu accepted you, I voted against it. If you enter the laboratory and still look like today, I will try my best to kick you out."

Pei Jing's tone was light, but it fell into Jiang Tong's ears like a thunderbolt. The combined effect of shame, anger and guilt made him flush from the neck up.He still wanted to refute, but Pei Jing was already impatient to listen.Just as the elevator opened with a ding, he stepped into the elevator and pressed the door close button in front of Jiang Tong.

Troubles are always like dominoes, one after another, which is tiring to deal with.When Jiang Tong came home, he laid himself down on the bed, almost wanting to fall asleep.

There is always something good going on.He swiped his phone to check the balance of his bank account, and the fee for writing a mid-term paper arrived in his account, the price of a box of lenalidomide.

A WeChat reminder message is drawn across the top of the screen.A late-night letter is always an ominous sign.He was a little nervous, and when he opened it, it turned out to be a friend request.

The mysterious friend named ftx has no avatar, no circle of friends, and no signature.Jiang Tong thought about it for a while, and found it ridiculous, how could Xiao Fengtai get his WeChat.

By coincidence, he passed ftx's friend request.

"Hi" he clicked on the screen: "Who are you?"

The mysterious friend didn't say a word. When Jiang Tong almost gave up and wanted to delete him again, two bubble boxes popped up from the bottom of the screen.

"I don't dislike the poem."

"I don't dislike you."

"That's right, I gave it to him." Lu She gnawed on the apple, squinting at Jiang Tong. "I haven't asked you yet, what does Master Xiao want you to do with WeChat?"

When the call came through, he almost thought he was hallucinating after being ill for too long.Xiao Fengtai's tone was flat, and he said that he had a question to ask Jiang Tong. Lu She really wanted to say that only ghosts will believe you, but he couldn't say no in person anyway.

It seems that this kid is in a fight with Jiang Tong, Lu She put down the phone, worried.Consider whether to leave the hospital early and let Jiang Tong go free.

Before he could move, Jiang Tong came to the door.

"He only applied for a friend, and hasn't spoken yet." Jiang Tong gathered the peeled fruit peels with his hands, threw them into the trash can, and took out a napkin to wipe off the water stains on the bedside table.

Lu She stared at him and sighed exaggeratedly.

"I don't know which girl has this luck." Lu She said sourly: "You said you, you look good, you are smart, you have a good temper, and you are so virtuous! Sister-in-law will not be too happy in the future."

"Don't introduce me to a girlfriend anymore." Jiang Tong smiled and shook his head: "I don't want to delay others."

Lu She hates iron for being weak: "It's all girls who beg me to match you up. Big brother, you should correct your understanding of yourself! Little girls don't bully young people and poor people, and you still deny yourself. You say you , Hypocritical or not? Do you want to do it or not?"

"What did Master Xiao say when he came to you?" Jiang Tong forcibly changed the subject.

"I just said that I want to ask you a question-hey, I'm telling you something serious, don't give me gossip!" Lu She was full of Beijing movies when she was in a hurry.

Jiang Tong began to pack his schoolbag: "There have been a lot of things in the laboratory recently. I won't come to see you these few weeks. You should recover well."

"Hmph! I don't have an ungrateful brother like you!"

Jiang Tong is indeed busy.Every morning when he opened his eyes, he stared at the ceiling, and Pei Jing's coffin face appeared in his mind.He knew that Pei Jing would do what he said.

Professor Gu's research in the field of monoclonal antibodies is considered to be the top in Asia. Jiang Tong squatted at the door of the office and blocked him for a month before he barely obtained the qualification to clean the test tubes in the laboratory.Compared with the students who have exchanged overseas, Jiang Tong lacks the opportunity to face-to-face with his favorite professor, and a heavyweight recommendation letter is especially important.

Professor Gu's laboratory is full of great talents, and Jiang Tong brushes the test tubes every day, not in a hurry to express himself.After cleaning the test tubes, he did not leave the laboratory, wandering around, doing some chores such as changing pipette tips, sorting slides, and even taking out the trash, sweeping the floor and cleaning the table, and quickly became one with the whole group.

Jiang Tong is especially favored by the sisters of graduate students.Life in the ivory tower is lonely, and it is a good thing to have a handsome boy dangling in front of his eyes every day.What's more, this little handsome guy works fast and well, and has a down-to-earth and humble attitude.

The revolutionary situation is very good, only Pei Jing is the only discordant note.Since the group experiment broke up unhappy, Pei Jing ignored Jiang Tong when she met him. Jiang Tong knew that he was wrong, and still greeted Pei Jing with a smile.

The sisters of the graduate students were aggrieved for him.

"Pei Jing was half-dead every day in college, Xiao Tongtong, don't take it to heart." Sister a wanted to comfort him, but the topic went off track all the way, and became a personal complaint against Pei Jing.

"When he becomes the boss in the future, he must be the meanest and the one with the most troubles!".

It's not true that Jiang Tong answered, nor did he not answer, he could only respond with an embarrassed but polite smile.

Sister B tried to save the situation: "Oh, don't blame him, the project assigned to him by the professor is not going well. Didn't you see that he wants to live in the laboratory every day recently."

"What's not going well?" Jiang Tong asked cautiously.

Senior sister B casually replied: "Cells are not easy to cultivate. I didn't listen to him in detail. It seems that bone marrow cells are very difficult to live in vitro."

"Don't talk about him, it's unlucky." Senior sister A's anger came and went quickly: "Xiao Tongtong, come and sing karaoke with us on weekends. After singing, I will let you do experiments with us."

"Let's see when the time comes." Jiang Tong said with a smile.

The lab machines hum constantly seven days a week, with the exception of Friday nights.A hard working week is over and the weekend is yet to come.In the gap between old fatigue and new joy, it is easy for people to slack off.Even if they have to come back to work overtime on Saturday and Sunday, Friday night is also a happy hour for the small migrant workers in the laboratory.

In the festive and peaceful atmosphere, only Pei Jing remained unmoved, thinking about his fateful bone marrow cells.He had a preliminary discussion with his mentor and tried several methods, but once they left the body, the bone marrow cells shrank and died like frosted eggplants.

If this continues, the patient can only be asked to draw bone marrow again.

I don't know if the patient's family members will come to the door to smash the laboratory.

Observations under the microscope showed unsatisfactory results.Pei Jing took off her glasses, rubbed the center of her brows, and silently resisted the throbbing pain in the back of her head.Footsteps came from behind him, and when he looked back, it turned out to be Jiang Tong.

Pei Jing immediately got up to pack her things.

"I have a suggestion." Jiang Tong hurriedly said: "The culture of bone marrow cells is not successful, it may be because of the medium environment and the real situation. Can you simulate the human body environment and try to culture bone marrow cells and stromal cells together?"

Pei Jing stopped what she was doing.

"Who told you?" he asked in a low voice, expressionless.Only those who are extremely close can discern a trace of almost nonexistent excitement from his icy eyes.

"I checked some literature." Jiang Tong said confidently: "Although it is not about bone marrow, it involves a similar experimental design. I don't think we will have a better choice besides this."

"Oh." Pei Jing said, continuing to tidy up the table.

"I'm going to discuss it with the professor" They walked out of the laboratory together.While waiting for the elevator, Pei Jing suddenly made a sound.

"If the plan is reasonable, you can assist me and do this part of the experiment together."

The pie fell from the sky, and Jiang Tong was hit by the pie, so he couldn't help but gape and couldn't speak for a while.

Pei Jing is strict, but extremely fair.Assisting him in the experiment goes well, and Jiang Tong will get a chance to show his face under the nose of Professor Gu.

He was so happy that he wanted to yell, but he couldn't calm down left and right, so he simply walked home.Phoenix trees are planted all over Singapore, and right now is the season. Large orange-red flowers are quietly blooming in the night, like pieces of burning red clouds in the dark.

Jiang Tong was in a turbulent mood. Everything he saw was beautiful. On impulse, he took a landscape photo and posted it on Moments.He almost never speaks out at ordinary times. He thought it was wrong and planned to delete it, but found that ftx had already liked the photo.

After refreshing again, ftx canceled the like again.

Jiang Tong found it funny, and poked into the dialog box: "Don't you like that photo?"

This time he replied in seconds: "it's not me."

Jiang Tong thought of teasing him: "Speak Chinese."

"My cousin stole my phone."

"No google translate allowed."

The news disappeared without a trace, and there was no reply.

Jiang Tong imagined that the little boy was so angry that his brows stood erect, and he threw his mobile phone on the bed with a cold snort, but he didn't realize that there was a smile on the corner of his mouth.
