"At that time, it will be clear at a glance whether the blood on your hand is yours or your brother's!"

The DNA of identical twins is indeed the same, but there will be differences in methylation modifications.

Describe it in an easy-to-understand way:

It's like two buildings built according to the same blueprint.

At the time the building was built, the two were almost identical.

However, as the number of occupants gradually increases, the decoration styles of each household are different, resulting in acquired differences.

Hayashi Shinichi is not trying to fool Tomoshi Tanaka.

Technically, there are ways to identify identical twins through DNA.

"This this…"

Tomoshi Tanaka was caught off guard by the terminology.

He was flustered for a while, and was almost scared out of the BGM, and was about to kneel down and confess.

However, under this panic...

Tomoshi Tanaka gradually stabilized his position——

His psychological quality is actually not strong, but as a social elite who reads books and newspapers every day, knowledge gave him the strength to fight to the end:

"Are you kidding me..."

"Officer Lin, were you bluffing and bluffing people just now?"

"I have read the latest popular science magazines, and those authoritative experts have said in the articles:"

"Now there is no technology to identify the DNA of identical twins!"

Tanaka Tomoshi gritted his teeth and said.

He believed that his knowledge reserve could not be wrong, so he dared to face the investigation directly.

But I didn't expect that when comparing knowledge with Lin Xinyi, he lost:

"Yeah, not yet."

"In this day and age, there is indeed no identification technology for identifying identical twins."

"But don't worry, the technology will be available soon—"

Lin Xinyi paused slightly, and said calmly:

"I'm going back to write the paper now and post it in a few days."

Tomoshi Tanaka: ""

He was dumbfounded by Lin Xinyi's earth-shattering words:

What are you doing... without appraising technology, just point the technology tree on the spot?

Can the case be solved like this?

Are you a forensic doctor or a scientist? !

"Humph! Be smart!"

Lin Xinyi's smile was full of disdain, but he secretly sighed in his heart:

Of course he doesn't have the ability to write papers.

In fact, even the long speech he just said was memorized on the spot not long ago.

However, Lin Xinyi's work happened to have a great interdisciplinary relationship with Hui Yuanai's major.

He doesn't have the ability to engage in scientific research, but his girlfriend does.

Not only that, but more than enough:

As a rare gifted scientific girl in the world, Haibara Ai brought N SCI papers as a dowry.

The first author's name can be written in Lin Xinyi's.

Thinking of this, Lin Xinyi couldn't help but feel the happiness of being taken care of by a rich woman:

This girlfriend... It's worth finding it!

Chapter 182 Mao Lilan's Date

Tomoshi Tanaka's calculations were good.

He faked the scene as a burglary, then climbed over the wall from behind the house and left the villa quietly.

Then, he chose to return to the scene on his own initiative after the police arrived and contacted him.

In this way, Tomoshi Tanaka, who "actively cooperates with the police investigation", can alleviate his own suspicion as much as possible, further mislead the police, and focus on the non-existent robber.

And even if this trick doesn't work as expected, and the worst happens, he still has the final guarantee:

That was the blood relationship between him and his elder brother, the DNA that the police couldn't identify at all.

But Tomoshi Tanaka did not expect...

Lin Xinyi actually made a technological innovation on the spot, subverting the theoretical basis he relied on.

"How, how is it possible..."

Thin cold sweat could not help oozing from Tomoshi Tanaka's forehead:

"This kind of technology that doesn't exist at all, how can we say that it breaks through!"

"You, are you making it up?!"

He still held that last ray of hope, and stubbornly resisted.

"Heh." Lin Xinyi smiled lightly, and asked in a playful tone: "Do you think that the principles I just talked about are all made up by me?"

"This..." Tomoshi Tanaka was speechless immediately:

Indeed, what Lin Xinyi said was so professional, it sounded so powerful that it made people feel guilty.

He explained step by step the theory of using DNA methylation modification to identify identical twins. This set of theories is clear and complete, but it doesn't look like a random compilation.

"The development of technology is very fast."

"The double helix structure of DNA was discovered by scientists, and it is only 40 years ago."

"It has only been a dozen years since DNA identification technology was applied to the field of criminal investigation."

"And in the not-too-distant 21st century, it will be the century of biological science!"

Although biochemical and environmental materials will become one of the four tiankeng majors widely rumored on the Internet in the future, it is undeniable that biological science has developed by leaps and bounds in the 21st century.

Specifically in the field of forensic science, many problems that could not be solved before will be solved one by one in the future.

"Now there is a theory for identifying identical twins."

"You may not believe that I can write a paper these days, but the criminal prosecution period for the murder case is 15 years!"

Lin Xinyi pressed on step by step, without giving the opponent any chance to breathe:

"Mr. Tomoshi Tanaka, you are so sure..."

"In the next 15 years, has the theory I just mentioned been unable to be transformed into practical technology?"

Hearing this, Tanaka Zhishi's heart was even more disturbed.

He used his spare reading results to challenge other people's professional theoretical knowledge, after all, he was too overconfident.

"I advise you to plead guilty now, and you can barely surrender yourself."

"Otherwise, when I use technical means to identify the blood spot samples in your nails, you won't even be able to win the chance of reducing your sentence."

"me…"

Tanaka Tomoshi's cheeks were completely soaked with sweat.

His psychological defense line, which was barely stabilized by relying on knowledge, finally completely collapsed at this moment:

"I plead guilty...I killed my brother."

After saying this, Tomoshi Tanaka was like a blade of grass that had been exposed to the sun, and his whole body became wilted:

"It's all because of him... he's not good."

"If he hadn't stayed at my house all this time, I wouldn't have hated him so much!"

It turned out that Tomoshi Tanaka's older brother, Kazuyu Tanaka, was a full-time writer.

He writes words that cannot be sold all day long, and works part-time but refuses to work, so he can only live in the house of his rich brother, eating and drinking.

This has been going on for more than ten years, until recently his younger brother wants to get married and start a family, but he still refuses to leave this villa and live alone.

Tomoshi Tanaka couldn't bear it anymore, so he killed this parasitic brother.

It is true that writing is a dead end.

"People always have to pay for what they do."

"Your brother is like this, and you are even more so."

Lin Xinyi sighed lightly, and signaled the police officers to take Tomoshi Tanaka down.

Tanaka Tomoshi no longer had the intention of resisting, and put on the handcuffs obediently.

The police officers took blood samples from his fingernails, then escorted him out of the villa and put him in a police car.

Lin Xinyi finished his work and followed him out of the villa.

Outside the villa, Miss Huiyuan was standing there quietly, looking at him with questioning eyes:

"Well, I should help you, right?"

There was a trace of undetectable concern hidden in her cold eyes, as if she was saying this to Lin Xinyi.

Lin Xinyi was moved, so he left the crowd and walked to Hui Yuanai's side, and said in a low voice, "Thank you."

"Thank you for..."
