National University of Korea

Yang Qing strolled through the campus of the National University, and through the guidance of the mobile phone map, he soon arrived in front of a building.

Standing in front of the building, Yang Qing saw a row of huge words on the floor, and Yang Qing guessed that what was written on it should be the Science Experimental Building.

Yang Qing counted the rows of windows, this building has a total of 6 floors.

I took out my phone and looked at the time, it was 9.50 in the morning, and there were still 10 minutes left before the agreed time.

Just as Yang Qing was about to find a bench to sit down, a fluent English voice came from the side.

"Hello, are you Wu Ren, Mr. Wu?"

Yang Qing heard the voice and turned his head in the direction where the voice came from, a woman with a book in her arms and black-rimmed glasses was standing behind her, this woman looked to be about 30 years old, wearing a white coat, and the badge on her left chest read: Park Dong-hyun.

"Are you Teacher Park?" asked Yang Qing tentatively.

"Yes!" Park Dong-hyun nodded and said apologetically: "I'm sorry Mr. Wu, I just finished teaching Xue and made you wait for a long time!"

Yang Qing waved his hand and said, "I just arrived!"

Park Dongxian smiled when he heard this and said, "Then Mr. Wu, please come with me!"

After Park Dong-hyun finished speaking, he led the way in front.

Yang Qing followed Park Dong-hyun into the experimental building, and then took the elevator to the 6th floor of the top floor.

Out of the stairs came into view of one after another rooms isolated by glass, although they were isolated by glass, but from the outside they could not see the situation inside, there was a sign hanging at the door of each room, the sign said the name of the room, but what was written Yang Qing didn't know, he couldn't understand the names marked in Korean.

Soon Park Dong-hyun took Yang Qing to the innermost part of the floor and stopped at the door of a room.

"This is it!" Park Dong-hyun said, then pulled out a card from his body, swiped it on the door, and with a dripping sound, the door was opened.

Push the door and enter, there is a room of about 200 square meters, which is full of all kinds of equipment, bottles and cans are neatly placed.

"This is one of the best laboratories in our national university, equipped with flow cytometers, pressure cycle drug preparation systems, automatic sterilizers, carbon dioxide incubators, droplet digital PCR systems, thermal cyclers, ultra-low temperature freezers, liquid nitrogen tanks, microplate readers, ultraviolet spectrophotometers, ......," Park Dong-hyun said, pointing to the equipment.

"You can use all the equipment here, in addition, we also provide commonly used virions, Cas9 lentivirus, adenovirus, various commonly used enzymes, EpFect transfection reagents and other commonly used experimental consumables, Mr. Wu can buy directly if he needs. Park Dongxian introduced this and looked at Yang Qingdao: "Mr. Wu, do you think you are still satisfied?"

Before coming, Yang Qing had talked to Park Dongxian about his needs, and he had already heard Park Dongxian say on the Internet that the laboratories were equipped with those equipment, and now that he saw the equipment with his own eyes, Yang Qing was still very satisfied with this laboratory, and nodded immediately and said: "Very good!"

Park Dong-hyun said with a smile: "The rental price is based on the 1 million a day we negotiated online, how many days do you want to rent?"

Yang Qing reached out and took down the bag on his back, took out a bag containing money from it, and threw it to Park Dongxian: "I don't know how long it will be rented, here is 50 million, you take it first!"

Park Dong-hyun reached out and took the bag thrown by Yang Qing, opened it and looked at it and said with a smile: "It's the first time I've seen so much cash? Mr. Wu is really special!"

Yang Qing smiled and said: "Cash is convenient to use!" After giving Park Dongxian 50 million, Yang Qing didn't have much cash in his hand, probably 50 million left, and the money he got from the robbers was only more than 100 million in total, and it cost a lot of money to stay in a hotel, but although Yang Qing didn't have too much money left, he wasn't worried, and the money in his international account hadn't been touched!

At this time, Park Dongxian carried the money bag and said, "Mr. Wu is familiar with the laboratory first, and I will go to the school to go through the procedures!"

"Okay! Thank you for your hard work, Mr. Park!" Yang Qing said with a smile.

Watching Park Dong-hyun leave the laboratory, Yang Qing began to check various equipment one by one in this laboratory, for the use of these equipment Yang Qing basically only heard about it, and did not really operate it, looking east and west, just as Yang Qing was trying to start the flow cytometer, Park Dong-hyun came back.

Park Dongxian looked at Yang Qing's unfamiliar movements and the hurried appearance in front of the instrument and said, "Mr. Wu?"

Hearing this, Yang Qing turned his head to look at Park Dongxian and said, "Teacher Park is back?"

Park Dongxian nodded and handed over a document: "This is a rental document!" and then handed Yang Qing a card: "This is a key card to enter and exit the laboratory, and Mr. Wu's money is also stored in it, if you need to buy something, you can directly swipe the card!"

Yang Qing took the card and said, "Okay!"

At this time, Park Dong-hyun asked, "I don't think Mr. Wu is too familiar with these devices, do you really want to study gene editing?"

"Hmm!" Yang Qing said when he heard this: "I have just started to get in touch with molecular biology, so I am not too familiar with these things!"

Park Dong-hyun nodded and asked, "If the DNA of the genome is contaminated with RNA, how should it be solved?"

Yang Qing coughed when he heard this: "I don't know, I'm just learning, and I haven't been exposed to specific problems yet!"

Park Dong-hyun continued, "What are the reasons for the low purity of plasmids?"

Yang Qing heard this question and replied: "I know this, there are three main reasons for the low purity of plasmids, the first is mixed protein, the second is mixed RNA, and the third is mixed genomic DNA. ”

Hearing Yang Qing's answer, Park Dong-hyun nodded, and then asked, "What are the main reasons for RNA degradation?"

Yang Qing replied, "......"

Next, Park Dongxian asked Yang Qing a few more questions about molecular biology, some Yang Qing could answer, some couldn't, Yang Qing had already seen it at this time, this Teacher Park must be a master of biology, although he asked some very basic questions, but each question is key knowledge, Yang Qing took the opportunity to take out the questions that he couldn't understand by watching the video before and asked Park Dongxian for advice.

From the beginning of the question and answer, to Yang Qing's continuous questioning, Park Dongxian replied, time passed unconsciously, and by the time Yang Qing came back to his senses, several hours had passed.

At this time, Yang Qing was full of admiration for this Park Dongxian, and the problem that he had spent a long time not knowing in the world was explained clearly in a few words by Park Dongxian, this Park Dongxian is really amazing, no wonder he is a teacher!

Park Dongxian looked at Yang Qing at this time and said, "Your foundation is a little poor, and it is a little difficult to study gene editing with your current foundation!"

Yang Qing nodded again and again: "Teacher Park is right, I don't know if Teacher Park has any good ways to let me improve my level quickly?"

Park Dong-hyun smiled when he heard this: "The best way is to keep doing experiments, and only in the process of experiments can you quickly master theoretical knowledge, but ......" Park Dong-hyun paused here when he said this.

"But what?" Yang Qing asked.

Park Dong-hyun heard Yang Qing's question and continued: "But if you do the experiment yourself, your progress will be very limited, you need a mentor, a mentor who can teach you by hand, so that you can make rapid progress!"

When Yang Qing heard Park Dongxian say this, he reacted immediately, this Park Dongxian wants to be his mentor!

Glancing at Park Dongxian carefully, Yang Qing saw a hint of scheming excitement on his face, and he really couldn't see it if he didn't look closely.

Why does this Park Dongxian want to be my mentor? Is it because I am handsome, Yang Qing was narcissistic, and then thought of another possibility, this Park teacher should be interested in his own money.

The thought in his heart flashed away, and Yang Qing said to Park Dongxian, "Can you be my mentor?"
