Coroner Coroner

Miyano Shiho opened his eyes again and started talking nonsense.

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

Because he knew that in the "future", DNA samples for old bloodstains would generally be extracted using more advanced nano-magnetic bead methods.

He had seen that the appraisers of Kesouyan didn't know the nano-magnetic bead method, and thought that this advanced technology hadn't been invented yet.

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

But now looking at what these researchers said, the world already has the magnetic bead method that can be used...

Why didn't Miyano tell him about it?

Lin Xinyi was puzzled, and Miyano Shiho seemed to feel that what he said just now was a bit unprofessional: "Because of patent issues, the cost of the magnetic bead method is high, and it is difficult to promote."

"Only by finding ways to improve the chelex-100 method, which is the most used method, can this method that can detect old DNA be extended to the police system across the country as soon as possible, and this critical technical gap can be filled in time."

"Promoting the technology early can also solve those unsolved cases that cannot be solved due to lack of technology."

"Is not it good?"

"Ah...you are right." Lin Xin nodded:

Indeed, he heard the teacher mention it in class before...

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 method kits.

Later, when China broke through the technology of magnetic bead nucleic acid extraction through independent research and development, those foreign manufacturers suddenly "discovered with conscience" and dived and lowered their prices.

"I didn't expect you to even consider the cost of promotion."

"As expected of Miyano, he easily thought of something that everyone didn't notice."

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

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

It was as if she was really just considering the cost of promotion.

"All right…"

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

"No one bothers us now."

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

"It needs to be soaked in ammonia water first, right?"

"What concentration should it be? I'll prepare it."

Without looking up, Lin Xin put on a mask, gloves, and goggles, and ran to prepare the reagents.

Miyano Shiho: "..."

Is studying biology really so interesting?

Chapter 134 Writing Tests, Read as Dating

Lonely men and widows, in this undisturbed laboratory, did some things related to DNA.

The whole thing was weirdly...boring.

Following Miyano Shiho's instructions, Lin Xin cut up the old blood-stained specimens he had brought and put them into EP tubes (microcentrifuge tubes).

Add ammonia, SDS, proteinase K...

Change the concentration, repeat the operation, and set up several control groups.

"Wait, to be conservative, soak in ammonia water for at least 3 hours first."

Miyano Shiho sat on the side with a cold face, looking at Lin Xinyi with a hint of anticipation:

It's time consuming to do this kind of experimentation...

From morning till night, Lin Xinyi had to stay with her in the laboratory.

For such a long time, it's impossible for this idiot to keep talking about biology with her, right?

After all, although it looks like an experiment on the surface now...

But Miyano Shiho knew in his heart, and Lin Xinyi should also know that they are dating now.

"Speaking of which, we have never been alone for a long time like today."

"Lin Xinyi, what will he talk to me about?"

Miyano Shiho, who had never dated before, felt a little nervous.

Now it takes 3 hours just to soak the test materials in ammonia water.

During this boring waiting time, if there is anything you want to say, you should tell her.

So Miyano Shiho began to wait quietly.

Lin Xinyi sat in front of her and began to wait quietly.

……

The air was a little silent, even awkward.

The two stared at each other, not knowing what to chat to pass the time.

"that…"

Lin Xinyi held back for a long time before he came up with a topic:

"How will we leave?"

"13000 rpm, 10 minutes away."

"..."

The two exchanged the details of the experiment, and the air became dead silent again.

At this time, Miyano Shiho suddenly discovered a fatal problem:

It seemed that she and Lin Xinyi had never chatted "normally".

They didn't talk very much before, but recently they talked a little more... But they never talked about personal issues like normal young men and women in a good relationship.

There's no way... Who made them both have "autistic" temperaments that don't like to talk.

It's like ice cubes meeting liquid nitrogen. When two people get together, the air will not be cold.

"No wonder he keeps asking me about biology..."

"It turns out that this guy is trying to find a common topic with me, and just wants to talk to me more."

Miyano Shiho suddenly realized that the problem might be in herself.

Because her life is too monotonous, let alone Lin Xinyi, even if she meets her sister, she has nothing to say about the current situation.

So, apart from talking about love, what else can she talk to Lin Xinyi about?

Talk about work?Lin Xinyi couldn't understand again.

Talk about life?Her life is as monotonous as a blank sheet of paper.

Talk about hobbies?Her biggest hobbies are reading fashion magazines and collecting designer bags.

Speaking of which, the brand-name bags she collected all these years were bought by Lin Xinyi...

But he has always played the role of a bill payment tool, but he has not shown any interest in the designer bag itself.

"Then what should we talk about?"

"How about I take the initiative...Ask him about his recent life?"

Miyano Shiho couldn't help but fell into deep thought.

At this time, Lin Xinyi suddenly broke the silence:

"That, Miyano?"

"Anyway, we have to wait a few hours for the experiment to continue, why not us..."

"Huh?" Miss Miyano opened her eyes expectantly.

"Shall we do animal testing?"

Lin Xinyi seemed to have discovered something suddenly, and suddenly got excited:

"Last time I asked you about the toxicology and mechanism of action of tetrodotoxin, but after all, I only learned about it verbally."

"I'm always a little uncertain about the dosage."

"Although the dose has been lowered, I am still worried that it will poison people to death."

"If you want to poison with precision, you can poison people 'just right' according to your needs... I think it is still necessary to do animal experiments to confirm the poisoning effect brought by different doses."

Ms. Miyano's expression quietly became subtle.

But Lin Xinyi didn't notice it at all, and just continued to say:

"That's right, Miyano."

"If you want to infer the dosage for humans through animal experiments, how should you convert the dosage for humans and experimental animals?"

Miyano Shiho: "..."

She never expected that her first date with Lin Xinyi...

The topic of dating is to talk about poisoning and the dose of poison.

Dating activities are to do animal experiments and kill rats with poison.

Can you be less romantic, fool?

Miyano Shiho instinctively complained about Lin Shinichi in his heart.

However, after being subconsciously depressed, she suddenly realized that he couldn't be blamed:

It is precisely because she is not good at communicating and not being good at bringing up topics.
