Miss Miyano was instinctively a little depressed.

It's like a cat that has been left out in the cold by a game-addicted shovel officer, lying there quietly with her little hands, and there is a faint resentment in her cold eyes.

But Lin Xinyi still sat in front of her and focused on thinking, and while thinking, he didn't forget to stuff food into his mouth.

A mouth is only concerned with eating, but does not speak.

It's as if he's come to dinner today, not to see her.

But how is this possible?

How could anyone risk disobeying Gin's orders just to come over and ask a question or have a meal?

Obviously, this guy has been rejected too much, and he has become the coward who didn't dare to express his heart before.

Even when I came back to accompany her, I had to find an excuse to carefully test her heart.

It's so stupid...

"It's no wonder that after so many years, people only feel a little bit about him now."

"This emotional intelligence... It's not saved at all, is it? ”

Shiho Miyano, who has basically zero social experience, suddenly discovers that he can still establish a sense of superiority in emotional intelligence in front of others.

"If I don't agree to him, he will probably be single for the rest of his life."

It seems that Shizuka met Nobita, and Miss Miyano already felt a little pity for Lin Shinichi in her heart.

And that's what she thought to herself...

Lin Xin wiped out the breakfast in a whirlwind, and suddenly raised his head:

"Miyano, the laboratory should have the corresponding DNA identification equipment, right?"

"If I could, I'd like to test the improved extraction method you mentioned in the lab."

"That way, if something goes wrong, feel free to ask you as an expert."

"Oh?" The corners of Shiho Miyano's mouth turned up slightly:

Really... The drunkard does not mean to drink.

"I knew, at the end of the day..."

"You came here today to let me accompany you to 'do the experiment', right?"

Shiho Miyano picked up the sandwich and took a bite of it, and the smile on the corner of his mouth became a little playful.

"Huh?" Lin Xinyi was slightly stunned:

He can do the DNA extraction operation himself, and he doesn't need to be accompanied by Shiho Miyano throughout the process.

And he only came to ask her for technical improvement ideas today, but he didn't expect this genius girl to end up in person.

After all, asking Shiho Miyano to accompany him to do this kind of simple experiment is like a college graduate who doesn't do it himself, but asks his mentor to help him complete the design...

This is clearly an excessive request.

"Well, you misunderstood..."

Lin Xinyi was trying to explain his intentions.

But Shiho Miyano finished the sandwich in his hand with a brisk expression, gently wiped his lips clean, and stood up neatly:

"No problem, I can accompany you."

"Huh?" Lin Xinyi was a little surprised: "No... Won't it delay your work? ”

"I don't have any work today."

Miss Miyano opened her eyes and said nonsense, and her flat expression was convincing:

"And, DNA extraction..."

"Occasionally doing this simple experiment is a way to reminisce about your childhood."

Saying that, Shiho Miyano habitually put his hands in his pockets, stood in front of the table playfully, and looked at Lin Shinichi, who still hadn't reacted:

"What are you doing in a daze?"

"If you don't want me to help, I'll go back and rest."

"Yes, I think!" Lin Xinyi immediately followed.

Although there were some surprises, the full-level master promised to take the fly in person, and of course this kind of good thing could not be missed.

In this way, Shiho Miyano led the way in front, and Lin Shinichi followed behind.

The two left the cafeteria area that Lin Shinichi was most familiar with, and walked around the high-security building to the experimental area where Shiho Miyano usually worked.

The busy people here are all researchers in white coats, most of whom are not young, and many of them are extremely smart and have lost their hair early.

Miyano Shiho's youthful and beautiful face appeared here, and it was a little disobedient to look at it.

But with her own wisdom and strength, this genius girl was able to use this excessively young face to win the majesty of being the chief researcher in front of a group of uncle-level subordinates:

"It's good that today's work goes according to plan, and I'm not involved."

"Also, help me prepare a PCR lab, I have an experiment to do."

Miyano Shitoshi methodically directs his subordinates to do things, and he has a kind of leadership temperament in his gestures.

And although those researchers stayed away from this cold genius girl in life, they were still very cooperative in their work.

They quickly helped sort out an empty lab.

And when Shiho Miyano took Lin Shinichi in, a researcher finally couldn't help but ask:

"Director Miyano, what kind of test are you going to do?"

Seeing that Shiho Miyano, who had excellent intelligence, suddenly took Lin Shinichi to do a "secret experiment", and the researchers were very curious about the content of this experiment.

Shiho Miyano maintained an indifferent posture and did not answer.

But Lin Xinyi replied honestly:

"I asked Miyano to help me with the research, using the modified Chelex-100 method to extract DNA samples from 12 years of old bloodstains."

"Uh... Extract DNA from old bloodstains?"

"There's no need for Director Miyano to do this kind of simple experiment."

The researchers looked at each other with puzzled faces.

They unconsciously said things that would embarrass the leader, and Director Miyano is very unhappy right now.

"Also, if it's about extracting old bloodstains..."

"Although the Chelex-100 method is easy to operate, it is still a bit flawed after all."

Completely ignoring the increasingly cold pretty face of their own leader, a group of scientific researchers discussed science one by one:

"After all, Chelex-100 is not effective at removing impurities and degraded DNA fragments."

"And there is no cell lysate to lyse the cells, and the temperature change and proteinase K are used to rupture the nuclear membrane to release DNA, and the DNA content and purity obtained are very affected."

"This method is still more suitable for samples with less contamination and less impurities."

"Instead of putting effort into improving the Chelex-100 method, it is better to use the most advanced nano-bead method today."

"The magnetic bead method uses cell lysate to promote changes in the cell membrane and nuclear membrane, and after obtaining DNA fragments, the DNA is bound to DNA through magnetic beads as a carrier, and it will not adsorb or bind to impurities."

"With this method, the success rate of extracting old bloodstain DNA should be higher."

"yes... And this one is more hassle-free. ”

"I heard that the German company Qiagen has just launched a commercial magnetic bead DNA extraction kit, and if necessary, it can be purchased directly from overseas."

After eagerly discussing with a few bald guys, they quickly came up with a simpler and more convenient solution.

But Miyano Shiho's expression was even colder:

What do you all know...

According to what you said, let Lin Xinyi go back to purchase magnetic bead kits...

Isn't that just driving people away?

Lin Xinyi consulted about the DNA extraction method, but the drunkard did not mean to drink, and asked her in disguise if she was willing to date him.

She kept silent and didn't mention the more advanced magnetic bead method, but she knew the meaning of the strings by hearing the strings, which was a disguised expression that she agreed to his invitation.

On the surface, it's an experiment, but it's actually dating.

Both of them tacitly did not express their hearts directly.

But it's all in plain sight.

She knew it, and he knew it.

So... You people with low emotional intelligence, don't meddle here!

Suddenly found that his emotional intelligence was still the highest in this laboratory, and Miyano Shiho's heart was very tired.

There was a little more cold air on her body.

However, because Miyano's face has always been so cold, everyone is used to it.

Therefore, when she is really unhappy, others will not realize it.

"Director Miyano, there is a more advanced magnetic bead method, and this kind of improved test against the Chelex-100 method is of little significance."

"Recently, our R&D progress has been quite rushed, so why don't you do this..."

The researchers discouraged them.

But Shiho Miyano stared at her steaming eyes and asked expressionlessly:

"You're teaching me how to do things?"

Researchers: "......"

"You know more about biology than I do?"

Shiho Miyano's tone was a little colder.

The researchers glanced at each other, and finally closed their mouths obediently in the leader's gaze that could freeze people to death, and left the laboratory in line.

Only one or two people in the laboratory, Shiho Miyano and Lin Xin, suddenly became quiet.

"Lin, we can do the experiment."

Shiho Miyano looked back with a flat expression.

She has just shown the majesty of leadership, and now she looks very heroic.

Lin Xinyi also followed unconsciously, and even lowered his voice:

"Miyano, that magnetic bead method..."

"The magnetic bead method is not easy to use."

Shiho Miyano opened his eyes again and said nonsense.

And even Lin Xinyi, a half-person, can hear that there is something wrong with this nonsense:

Because he knows that in the "future", DNA samples for old blood stains are generally extracted using the more advanced nano-magnetic bead method.

He originally saw that the appraisers of the scientific search and research did not know the nano-magnetic bead method, and thought that this advanced technology had not yet been invented.

That's why he retreated to the next best thing, thinking about how to improve the current DNA extraction method to extract the DNA of old bloodstains.

But now that these researchers are saying, there is now a magnetic bead method in this world...

Why didn't Miyano tell him about this?

Lin Xinyi was puzzled in his heart, and Miyano Shiho also seemed to feel that what he just said was a little too unprofessional: "Because of the patent problem, the cost of the magnetic bead method is high, and it is difficult to promote." ”

"Only by finding a way to improve the most widely used Chelex-100 method can we quickly expand this method of testing obsolete DNA to the police system across the country and fill this critical technology gap in time."

"The sooner the technology is promoted, the sooner the unsolved cases that cannot be solved due to the lack of technology."

"Isn't that bad?"

"Uh... That's right. Lin Xin nodded:

Indeed, he had heard the teacher mention it in his previous lessons...

The magnetic bead method was promoted late in China, because of the lack of independent intellectual property rights, which led to the high price of imported magnetic bead kits.

Later, when China made a breakthrough in the technology of magnetic bead nucleic acid extraction through independent research and development, those foreign manufacturers suddenly "discovered their conscience" and dived to reduce prices.

"I didn't expect you to even take the issue of promotion costs into account."

"It's worthy of Miyano, and he easily thinks of things that everyone can't notice."

Lin Shinichi expressed his admiration for Miyano Shiho's carefulness from the bottom of his heart.

"Hmm." Shiho Miyano naturally accepted Shinichi's compliment.

It's like, she's really just thinking about the cost of promotion.

"Alright..."

Shiho Miyano walked to the door and slowly closed the door:

"No one bothers us now."

"Are you going to do the experiment first, or do you want to talk to me first..."

"You need to soak in ammonia first, right?"

"What concentration should I configure? I'll prepare. ”

Lin Xin didn't lift his head, directly put on a mask, gloves, and goggles, and ran to prepare reagents.

Shiho Miyano: "......"

Student biology, is it really that interesting?
