Yang Qing followed Park Dongxian back to the laboratory, glanced at the laboratory with both eyes, and found that the laboratory had been cleaned up neatly at this time, so he immediately said to Park Dongxian: "Teacher, have you cleaned up the laboratory?"

"Hmm!" Park Dong-hyun said in a reproachful tone: "I haven't told you many times, every time you finish the experiment, you must clean up and leave, don't do it next time!"

"I know, teacher, not next time!" Yang Qing nodded.

Park Dong-hyun came to the incubator at this time and said, "That is the virus stock solution you cultivated?"

"It's BS-1!" replied Yang Qing.

On the way here, Yang Qing had already told Park Dong-hyun that he had cultivated the virus stock solution, and now that he was back in the laboratory, Park Dong-hyun couldn't wait to study it.

When Park Dong-hyun heard this, he opened the incubator, there were three layers in the incubator, and there were a lot of labeled glass tubes on each layer, which were filled with all kinds of liquids, Park Dong-hyun glanced at the top row, and did not find the BS-1 that Yang Qing said, and then looked at the second row, the second row was also not, and then Park Dong-hyun looked at the third row, but still did not find it.

"Well, why not?" said Park Dong-hyun, and searched again from the top, but there was still nothing.

Yang Qing heard Park Dongxian's words and walked over: "Didn't you find it?"

Park Dong-hyun shook his head and said, "No!"

Yang Qing came to the incubator and looked at the glass tubes inside, but did not find the virus liquid he had configured.

"Could it be that I forgot to put it back in the incubator?" Yang Qing recalled his previous memory, and then turned to Park Dongxian and said, "Teacher, when you cleaned up the laboratory, did you find a test tube on the test bench, there should be some virus stock solution in it." ”

Park Dong-hyun heard Yang Qing's words and recalled the scene when he cleaned up the laboratory: "It seems that there is one, didn't you put the virus stock solution back into the incubator?"

"I was so sleepy, I forgot about it!" Yang Qing whispered.

"What kind of virus did you use as a vector?" Park Dong-hyun asked suddenly.

"Adenovirus!" Yang Qing said with a puzzled expression.

"It's broken!" Park Dong-hyun suddenly turned around and ran outside.

"Teacher, what's wrong?" Yang Qing followed.

"I threw the virus stock solution and commonly used lab waste directly into the garbage hall!" Park Dong-hyun replied as he walked.

"So what?" Yang Qing said puzzled.

"Adenovirus is one of the most mutated virions, especially in the garbage heap, and it is very easy to combine with other bacteria to produce new variants!"

"Teacher, don't worry, the virus stock solution I configured is not contagious!"

"It doesn't matter if he's contagious or not, the important thing is that he might evolve to be infectious!"

"How so, teacher, didn't you say that adenovirus is the best transfection vector?"

"That's right, adenovirus is the best vector for transfection, and it's also the best vector for bacteria!"

Yang Qing was stunned when he heard this, the best bacterial carrier means that it is likely to evolve a superbug.

While talking, the elevator had reached the first floor, and Park Dong-hyun and Yang Qing trotted all the way to the back of the experimental building.

There is a garbage storage area at the back of the laboratory building, which is the garbage chute exit of the laboratory building.

The garbage on each floor of the laboratory building will be thrown into the garbage channel, which greatly facilitates the garbage disposal on each floor, and also allows the garbage truck to easily transport the garbage to the car.

Coming to the exit of the garbage road, Park Dong-hyun looked at the cleaned garbage dump and said worriedly: "It's over!"

"Teacher, don't worry, this garbage will be sent to be incinerated, and the virus will also be incinerated clean!" Yang Qing comforted.

Park Dong-hyun nodded when he heard this, and said, "I hope!"

The garbage had been cleaned up, and it was almost impossible to retrieve the discarded virus liquid, so Park Dong-hyun and Yang Qing immediately returned to the laboratory.

"Teacher, you don't have to worry too much, those virus stock solutions are not harmful, they just change the color of human skin, and there is no harm to the body, even if it evolves a virus, it is not too harmful!" Yang Qing looked at Park Dongxian, who was still a little worried, and comforted.

Park Dongxian glanced at Yang Qingdao and said, "You're right, there may not be a problem I'm worried about!"

Yang Qing saw that Park Dongxian was no longer worried, and said, "Teacher, I'll prepare a new virus stock solution now!"

Park Dong-hyun nodded and said, "Okay, I'll help you!"

"Okay!" Yang Qing said and sat down in front of the test bench.

…………

Seven days later, in the laboratory.

Park Dong-hyun and Yang Qing stood side by side, both of them looking at the row of glass boxes placed on the test bench, each of which was very small, only 15 centimeters long. There are 10 glass boxes that fill a test bench, and in each of them is a small mouse, but the rats are all different colors.

From the left is the mouse, then the color begins to deepen into a small gray squirrel, and when the tenth glass box is an all-black black mouse, from the left to the right you can see that the color of these mice is a gradual process from white to black.

"Teacher, you are so powerful, you can accurately control the performance of DNA!" Yang Qing sighed, and couldn't help but glance at Park Dongxian beside him.

Yang Qing didn't expect Park Dong-hyun to be so powerful, he just took out the most basic skin color fragment from the gene pool, and Park Dong-hyun can accurately control the performance of these genes, which is very close to the orderly editing technology mentioned in the book "Gene Editing: Programming Creatures".

Park Dong-hyun said: "This is all basic operation, you can edit freely after learning from me for a while!"

Yang Qing nodded and said, "Don't worry, teacher, I will study hard!"

Park Dong-hyun raised his hand, pointed to a row of guinea pigs and said, "Do you know what this means?"

Yang Qing cooperated: "What does it mean?"

Park Dongxian stared at Yang Qing with a fanatical gaze and said, "This means that there is countless wealth!"

"Huh?" Yang Qing looked at Park Dongxian suspiciously.

Park continued: "Now we can precisely control the color of the skin, which means that we can produce whitening products that allow all women who want to be white overnight to have baby-like white skin, and if you think about it, this is a big business opportunity, and almost all women will go crazy about it." ”

Yang Qing was also stunned when she heard Park Dongxian's words, yes, how many women in this world spend a lot of money to buy those whitening cosmetics in order to become whiter, but the effect received is very limited, if there is a product that can directly change the skin color, these women will definitely go crazy.

Thinking of this, Yang Qing's eyes lit up and said, "Teacher, how much money do you need!"
