Chapter 121: came back

　　　　 Tang Xin is a good girl with a soft personality.
　　 In fact, he didn't want to be Zhou Wen's assistant, let alone go to Jiangzhou with him.
　　 But I am embarrassed to say it in person, so I can only go back and complain to my classmates.
　　 Then when her mother called to ask, she said Zhou Wen's words truthfully.
　　 Unlike Tang Xin, Tang Xin’s mother still trusts Zhou Wen. I heard that Zhou Wen is going to take her daughter to work in Jiangzhou, so she called to confirm.
　　 After confirming that what Zhou Wen said was true, Tang Xin's mother smiled and said, "Tang Xin will leave it to you! If she doesn't understand anything later, please teach her more."
　　 "Good Aunt Wang, I will take care of Tang Xin, don't worry."
　　 "Then thank you Zhou Wen, I have time to come home for dinner."
　　 "Hmm, ok..."
After 　　 hung up, Zuo Mengmeng’s group chat video came back.

　　 At 6:30 the next morning, Tang Xin came to the side of the provincial highway.
　　 Zheng Lina, the classmate who sent her here, was yawning.
　　 "Xin Xin, let me tell you, when you get there, if you find something is wrong, do you know if you have to run away immediately?
　　 Or you call me, I will rescue you.
　　 Don't be silly, he is what he says.
　　Although I haven't seen your unbeatable form yet, according to your description, it is basically certain that this is a guy who runs a train with his mouth full.
　　 Go to Baidu Baike to revise the entry, and then rub the popularity again, and become a celebrity.
　　啧啧啧, people nowadays can do anything for money, for face.
　　 Xinxin, don't be stupid, and don't listen to him fooling around.
　　 The most important point is to protect yourself.
　　 There are too many guys with human faces and animal hearts..."
　　 Just as Zheng Lina was talking cracklingly, Yu Guang saw two daytime running lights coming from the north.
　　 In a blink of an eye the car has come to them, and then slowly stopped.
　　 Zheng Lina took a closer look. It was a royal blue Audi with a huge body that covered the line of sight.
　　 Without waiting for her doubts to be heard, after the car stopped, the door opened, and a young man came down from the inside and smiled: "Sorry, you have been waiting for a long time."
　　 Talking about Zhou Wen, he went to open the trunk and helped Tang Xin put the suitcase and shoulder bag in.
　　 closed the door and smiled: "Let's go, get in the car."
　　 Tang Xin and Zheng Lina, only then reacted.
　　 Especially Zheng Lina, after looking at the brand-new car body, he also took a look at the model, Q7. In my impression, this model of Audi seems to cost millions.
　　 Zheng Lina asked Tang Xin in surprise: "It doesn't look like a liar."
　　 Tang Xin blushed and said, "I... didn't say he was a liar."
　　 Zhou Wen smiled and said: "What's the matter?"
　　 "Uh, nothing." Zheng Lina replied, "I just want to ask you a question."
"what?"
　　 "What the do you do?"
　　 "It's a medical test."
　　 "That..." Zheng Lina pointed to the car and said, "This car is yours?"
　　 Zheng Lina asked Tang Xin, knowing that Zhou Wen's family conditions are average.
　　 If the car is really his, then the report on the Internet is probably true.
　　 Zhou Wen said jokingly: "The colleague I borrowed from."
　　 "This is about the same~" Zheng Lina muttered to herself.
　　 She didn't think Zhou Wen was joking at all, but took him seriously, otherwise she couldn't explain it at all.
　　 "Your name is Zhou Wen, right? Even though you are her cousin, I still want to tell you that Xinxin has a very gentle personality, so don't bully her.
　　 If you have a job, you can find the best, and even if you can’t find it, send her back to me intact, have you heard? "
　　 "Uh... I know."
　　 Zhou Wen discovered that next to a girl with a gentle personality, there will always be a stronger classmate, girlfriend, or something.
　　 is like Shen Xue and Zuo Mengmeng.
　　 But fortunately, the pair was separated immediately.
　　 "Then let's go~"
　　 "Call me when you arrive~" Zheng Lina went up and hugged Tang Xin.
"Bon Voyage."
　　 "Goodbye—"
　　 Zhou Wen opened slowly, and arrived at Jiangzhou City Hospital at ten o'clock in the morning.
When arriving at the testing center building, Zhou Wen said: "I'll go in to deal with something. You will sit in the car for a while. If you are bored, go around the hospital and don't run far. Give you the key. Remember to lock it when you get off Car, this is the lock key..."
　　 Zhou Wen confessed to Tang Xin, and then entered the testing center.
　　 First, I went to the comprehensive laboratory on the sixth floor. It took an hour to extract 12 strains of DNA. This is for PCR.
　　 then went to the office of the Prion Research Group on the seventh floor.
　　 Dong Wenying was doing data in his office, and seeing Zhou Wen came, she was pleasantly surprised: "Hey, when did you come back, Zhou Wen?"
　　 "I just got here for a while, I helped the PCR side to extract a DNA~" Zhou Wen explained, and then asked: "Zhang Pengfei, how is the data sorting?"
　　 Dong Wenying took a bunch of data from the desk and handed it over: "This is just sorted out this morning. They are all very valuable first-hand information."
　　 Zhou Wen sat down and studied the data report carefully.
　　 Then I couldn't help thinking of prion inactivation in my mind, and my thinking couldn't help but spread...
　　 Zhou Wen thought that it was thirty minutes. After returning to his mind, she realized that Dong Wenying had left long ago. Looking at the time, it was already twelve.
　　 He suddenly remembered that Tang Xin was still waiting for him in the car downstairs, and went downstairs quickly.
　　 When Zhou Wen came downstairs, he found that Tang Xin was sitting in the car, holding his mobile phone, reading novels with relish.
　　 "Sorry, I forgot to be busy just now, are you in a hurry?"
"No."
　　 "Go, let's have lunch~" Zhou Wen asked casually on the road: "Do you like reading novels?"
　　 Tang Xin: "Hmm!"
　　 "What type do you like?"
　　 "Speak now, go through..."
　　 After dinner, Zhou Wen first took Tang Xin to the science and technology park laboratory.
　　 After staying here for half an hour, he went to the Institute of Drug Research.
　　 When he entered the door of the Blood Research Center, Tang Xin, who had been sitting quietly in the passenger seat, finally couldn't help but ask: "Why are we here?"
　　 Tang Xin was really curious at this time. What kind of identity is this cousin?
　　 Why don't you go to work in the hospital, but run around?
　　 And some people I saw were very kind to him.
　　 Zhou Wen smiled and said, "I will show you where to work in the future."
　　 "Oh~"
　　 Tang Xin responded and turned to look out the window.
　　 She discovered that the environment of this blood research center is really good, with birds and flowers, green trees, and the buildings of the Republic of China style with red walls and green tiles, which look very beautiful.
　　 If I can work here, it would be a very pleasant thing.
　　 However, it may be preconceived. Even if he has already arrived at the place at this time, Tang Xin still feels that Zhou Wen is bragging.
　　 Zhou Wen drove to the drug laboratory building. After registering in the lobby downstairs, he was about to take Tang Xin upstairs when he happened to see Chen Ruobing.
　　 And when Chen Ruobing saw Zhou Wen, his eyes suddenly brightened, "Hey, Zhou Wen, when did you come back?"
　　 "This morning..."
　　 The two exchanged greetings, and Chen Ruobing noticed Tang Xin next to him, and smiled and asked, "Who is this?"
　　 "Tang Xin, the assistant I just hired."
　　 Zhou Wen explained, and then introduced to Tang Xin: "This is Director Chen Ruobing of the Institute of Pharmaceutical Research. You can consult Director Chen when I am away in the future."
　　 Tang Xin bowed slightly and said shyly: "Hello, Director Chen."
　　 "Well, hello~"
　　 Chen Ruobing nodded with a smile, and then asked Zhou Wen, "How did you purify your biotin and avidin?"
　　 Zhou Wen: "This is simple, you first like this..."
　　 The two talked as they walked.
　　 Tang Xin followed them step by step before going to the elevator.
　　 soon came to the fourth floor laboratory.
　　 Seeing Chen Ruobing and Zhou Wen come in, the researchers inside said hello.
　　 Many people saw Zhou Wen, and their eyes even showed a look of worship.
　　 Chen Ruobing took Zhou Wen to the dressing room and changed into sterile clothes. Then, under the guidance of Zhou Wen, he began to purify biotin and avidin.
　　Biotin and avidin can be used not only for disease detection, but also for clinical drug testing, which is also of great help.
　　 However, biotin and avidin are still being tested, so it will take some time to wait for clinical use.
　　 At this moment, Chen Ruobing is really thankful that the original decision to let Zhou Wen enter the Institute of Pharmaceutical Research...
　　 The time in the laboratory was very fast, four hours passed in a blink of an eye.
　　 Zhou Wen carefully extracted the purified streptavidin from the vessel and poured it into a test tube.
　　 After putting down the extraction gun, Zhou Wen said: "Okay~ It can be used now."
　　 Chen Ruobing picked up the test tube with biotin, looked at the viscous liquid inside, and said happily, "Thank you~"
　　 "You're welcome~"
　　 Zhou Wen walked to the sink and said while washing his hands: "Remember, when using it, follow the dosage instructions strictly, not more than 100μg at a time. If it is too much, it will not only waste, but also the effect will not be good."
　　 "I know~" Chen Ruobing put the biotin in the ice box for preservation~EbookFREE.me~ walked over and took off his gloves and washed his hands, "Please have dinner tonight."
　　 "You don't need to eat~" After a pause, Zhou Wen followed: "But I have to kiss you and do me a favor, so that my assistant will be named in the institute. I will pay the salary and insurance personally, okay?"
　　 "What's the problem with this~" Chen Ruobing readily agreed, and followed: "If it doesn't work, just hang it under the name of the research institute. You can help her with hardware."
　　 "That's not necessary. She is my personal assistant, and it is inappropriate for the institute to pay for it."
　　 After a pause, Zhou Wen followed: "Oh, one more thing, do you know where there is a house nearby..."
　　 Ten minutes later, Zhou Wen, Chen Ruobing and Tang Xin stood in front of a beautiful four-story building.
　　 This is still in the blood center.
　　 And this building is the staff dormitory of the Institute of Pharmaceutical Research. Chen Ruobing has a bachelor apartment here. Later, after her parents settled in Jiangzhou, she moved back home, so it was always empty.
　　 just lent it to Tang Xin to live.
　　Opening the security door, a musty smell that has not been ventilated for a long time rushed towards him.
　　 At this moment, Chen Ruobing's phone rang. After answering the call, he gave Zhou Wen the key and left in a hurry...
