After leaving the sample processing group on the third floor, Zhou Wen rushed to the fourth floor's pathological testing group.
It was 10:15 a.m., so if he hurried the process, it might be possible to complete the test before lunchtime. Then, he would be able to leave work on time today.
On his way, he opened the system, and a mission popped up.
[Mission: Complete the pathological test for Sun Jing's friend.
Reward: 300 course XP, 300 points, 1x Loot box Chance (Black metal)
[Do you accept?]
Zhou Wen was a little amused to see the black metal loot box as a reward again.
After unboxing it twice, he realized that the value of the loot box reward largely depended on the difficulty of the task.
The more challenging the task, the higher the value of the reward, and vice versa.
It was the same for the course XP and points.
In the end, Zhou Wen accepted the mission.
After arriving at the pathological testing group, Zhou Wen found the group leader, who was also Yang Liqun's deputy leader, Luo Siyu, to explain what he wanted to do.
Naturally, Luo Siyu had heard of Zhou Wen before; although they were not close, she happily agreed to Zhou Wen's proposal.
Since Zhou Wen was doing it by himself and did not need her permission, helping him would both sell him a favor and reduce the group's burden, so why not?
Luo Siyu went to the pathological testing lab with him, found Sun Jing's friend's pathological sample in the freezing storage, informed the group members, gave Zhou Wen access to the lab equipment, and left.
After Luo Siyu left, Zhou Wen immediately started the electrophoresis experiment.
Fortunately, the sample was already frozen. If not, he would have to wait for another 24 hours!
The procedure was similar to what he had learned in university: add liquid nitrogen to the mortar, grind the sample cell tissue, add sterile water and grind further, add DNase and RNase before extraction to remove the host gene fragments, and finally, put the mixture into a centrifuge to begin separating the contents.
Throughout the whole process, Zhou Wen's movements were rather intense, causing the 7-8 other testers to stare at him in shock.
Was he doing a pathological test or putting on a live show?
"What is he doing? Entertaining us?"
"How do I know? Why don't you ask him?"
"Hey, bro, what are you doing?" A tester could not help but ask.
Zhou Wen was waiting next to the centrifuge at the time and smiled as he said, "Testing for pathogens."
The tester was amused. "You can't extract the pathogenic DNA this way."
Zhou Wen smiled again. "You can."
He used True Vision throughout the whole process, so he was careful with the details despite looking as though he was making rough estimations. Additionally, the pathogenic DNA did not need to be replicated, so the extracted concentration did not matter. His goal was to complete the process as quickly as possible.
Needless to say, the tester was unaware of the situation. Seeing that Zhou Wen insisted on his method, he shook his head in amusement and left.
The other testers saw his defeated retreat and chuckled silently.
Meanwhile, Zhou Wen quickly extracted the supernatant after the centrifugation was complete. He pipetted it and centrifuged the mixture again. Then, he dropped a droplet of the mixture into the gel electrophoresis machine to begin the virus comparison analysis, which compares the results with the pathogenic gene library of America and NCBI to determine the pathogens present.
He was still very intense, as though he was in a hurry in fear that if he did it any slower, he would not be able to make it in time for lunch. Since he handled everything rather quickly, it seemed as though he was somewhat imprecise.
Two female testers at the side could not help but burst out laughing as they watched him move around. This guy was too entertaining.
In the whole testing center, there were a few hundred lab scientists, researchers, and testers. Nobody dared to handle the samples the way Zhou Wen did in fear of any mistakes that could cause their work to go to waste.
Zhou Wen was the only exception trying to force a miracle. With his method, the onlookers assumed that he would only be able to detect pathogens when pigs could fly.
After completing the electrophoresis detection procedure, Zhou Wen glanced at the clock. It was 11:30 a.m., just in time for lunch.
He stretched his arms and realized that everyone was staring at him.
Zhou Wen touched his face self-consciously and asked, "What's wrong?"
Everyone was amused by his innocent look and laughed while taking off their gloves.
...
After lunch, Zhou Wen had nothing much to do as the pathological test result would only come out at 5 p.m.
Since he was free, he went to the inpatient department. The old lady was discussing Guo Baichun's discharge procedures with the doctor in his office.
The doctor understood Guo Baichun's situation. His cancerous cells had already invaded his entire body, so living in the hospital would do nothing other than delay his death. Since the old lady requested a discharge, he had nothing much to say against it.
After explaining each of the medications and their dosages to the old lady, he signed his approval on the discharge form.
The old lady had already packed their things, so Zhou Wen helped the nurse to carry Guo Baichun onto his wheelchair and walked out of the hospital with them.
The hospital's escort service was parked under the canopy at the door. Other than the driver, there was also a doctor on board.
After sending Guo Baichun into the vehicle, the old lady patted Zhou Wen's hand and said, "Go back to work, kiddo."
"Okay," Zhou Wen nodded and secretly handed her the painkillers. Then, he said bye to Guo Baichun, "Bye, Uncle Guo. "
Other than looking a little skinny, Guo Baichun was feeling quite well. He nodded and returned a weak smile. "Bye."
After sending them off, Zhou Wen returned to the PCR lab in the testing center.
He helped Wen Hao and Su Qi with preparing the reagents.
Time flew by, and soon, it was 4:30 p.m., so Zhou Wen left the PCR lab and went to the pathological testing group.
After waiting for another 40 minutes, the results were out.
As soon as Zhou Wen picked up the electrophoresis report, several people gathered around him.
In Zhou Wen's electrophoresis report, the electrophoresis band on the right was crystal clear, and in the analysis report on the left, one of the polyomaviruses (Py) was tested positive.
At the bottom, the test summary stated, "SV40, BKV, and JKV are not confirmed, it is recommended to…"
WTF??? He f*cking did it?
The testers were all in shock by the outcome of the report.
Some people even started wondering if Zhou Wen simply printed a test report from the computer while others started doubting themselves. Had they been testing the wrong way? Were they supposed to be rougher with the pathogenic DNA to force a miracle?
Nevertheless, they very quickly gave up on the ideas.
Reports could not be falsified so easily. Every single report that was printed represented a patient's life and a family's concern; who would dare to mess around?
No one would be able to bear the consequences.
Furthermore, a miracle was even more ridiculous.
They used to be as rough as Zhou Wen, and it resulted in failure after failure. The reality was that being hasty and imprecise only led to failures for them.
As for Zhou Wen... He was just superhuman.
"How, how did you manage to test it?" The tester who said that Zhou Wen would not be able to extract the pathogenic DNA asked awkwardly.
Zhou Wen smiled. "The same way you guys do it!"
The tester pouted. Of course, he knew that he did it the same way as them. They watched Zhou Wen for the whole day, waiting to see his reaction when the electrophoresis result was out!
It turned out they were the ones who embarrassed themselves.
Just when he wanted to ask more questions, the tester noticed Zhou Wen's smiley expression.
He realized that Zhou Wen had been hiding it all the while - he was, in reality, an expert in pathological testing.
He knew exactly what they were thinking; he just did not bother to respond.
They were waiting for him to be fooled, yet they fooled themselves!
He felt like his face was set on fire at first, but he quickly realized that it was a great opportunity for him to learn.
He smiled and asked, "My name is Qin Haitao; what's yours?"
"Zhou Wen."
"I'll call you Mr. Zhou," Qin Haitao said sincerely.
Zhou Wen had never got to enjoy the respect of his peers. Even when Sun Jing called him an expert, she had said it teasingly.
But Qin Haitao was different; Zhou Wen could feel that he, a young man who seemed to be 2-3 years older than him, was very sincere.
Zhou Wen replied humbly, "No, no, no. Don't. I am just a normal lab scientist like you."
Qin Haitao did not bother to dispute Zhou Wen, so he just continued, "Nice to meet you, Mr. Zhou. I just wanted to ask if you could teach me your ways. Why is it that, if I operate the same procedures as you, a tiny mistake could easily lead to failure?"
Although Zhou Wen acted humbly, he felt very flattered. He smiled as he responded, "That's because there are some key points that you missed out, for instance…"
Since Qin Haitao was so respectful of him, Zhou Wen decided to make an exception and teach him a few key points to pay attention to.
These were the things that he discovered using his Truevision, which even money could not buy.
Of course, he omitted technological advancements like the permeate concentration. That was his money-making secret.
Qin Haitao and one other tester listened carefully, occasionally being hit by realizations and epiphanies.
As for the other testers, they were probably feeling a little embarrassed and left after a while.
After speaking for 5 minutes, Zhou Wen paused. "That's it. If you manage these key points carefully, you won't fail so easily anymore."
Qin Haitao nodded. He felt like, within that short time, many things that he never understood made perfect sense now.
Therefore, Qin Haitao answered gratefully, "Thank you for your advice, Mr. Zhou."
"Thank you, Mr. Zhou."
"No problem."
Zhou Wen raised the report in his hand and asked, "What do I do after this? It's my first time conducting a pathological test, so I'm not familiar with the process."
Qin Haitao smiled. "That's simple; just hand it to me, and I will key it into the system for you…"
