Tomosaki Tanaka's abacus played well.

He faked the scene as a burglary, and then went out through the back of the house and quietly left the villa.

Then, he chose to return to the scene after the police arrived and contacted him.

In this way, Tomoshi Tanaka, who "actively cooperated with the police investigation", was able to alleviate his suspicions as much as possible, further mislead the police, and focus on the non-existent burglar.

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

That's the blood relationship between him and his brother's cousin, the DNA that the police can't identify at all.

But Tomoshi Tanaka didn't expect ...

Lin Xinyi actually engaged in scientific and technological innovation on the spot, subverting the theoretical basis he relied on.

"How, how is it possible..."

Tomoshi Tanaka's forehead couldn't help but ooze a thin layer of cold sweat:

"This kind of technology that doesn't exist at all, how can it be said that a breakthrough is a breakthrough!"

"Y-You're making it up, aren't you?!"

He still had the last glimmer of hope, and he resisted stubbornly.

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

"This..."Tomosaki Tanaka was suddenly speechless:

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

He elaborated step by step the theory of using DNA methylation modification to identify identical twins, which was clear and complete, but not at all like a random fabrication.

"Technology is evolving very quickly."

"It's only been 40 years since the double helix structure of DNA was discovered by scientists."

"DNA identification technology has only been applied to the field of criminal investigation for more than ten years."

"And in the 21st century, which is not too far in the future, it will be the century of biological science!"

Although biochemical ring materials have become the four major sinkhole specialties that are rumored on the Internet in the future, it is undeniable that biological science has developed by leaps and bounds in the 21st century.

Specific to 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 thesis these days, but the criminal prosecution period for a homicide case is 15 years!"

Lin Xinyi pressed forward step by step, not giving the other party a chance to breathe:

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

"In the next 15 years, will the theory I just mentioned not be able to be translated into practical technology?"

Hearing this, Tanaka Chishi's heart was even more uneasy.

Using his own amateur reading results to challenge other people's professional theoretical knowledge, after all, he is too self-conscious.

"I advise you to confess your sins now, and you can barely turn yourself in."

"Otherwise, when I use technical means to identify the blood spot sample in your fingernails, you won't even be able to get this chance to reduce your sentence."

"I... I..."

Tomoshi Tanaka's cheeks were completely soaked with sweat.

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

"I plead guilty... I was the one who killed my brother. ”

Saying this, Tanaka Chishi was like a blade of grass that had been exposed to the sun, and the whole person wilted:

"It's all because he... It's that he's not good. ”

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

It turned out that Kazuyu Tanaka, the elder brother of Tomoshi Tanaka, was a full-time writer.

He writes some words that can't be sold for money all day long, and he refuses to work part-time, so he can only rely on his rich brother's house to live, eating and drinking.

This Lai has been for more than ten years, and his younger brother recently wanted to get married and start a family, but he still refused to leave this villa and live alone.

Tanaka couldn't bear it anymore, so he killed this parasite-like brother.

Writing a dead end is true.

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

"That's true of your brother, and even more so of you."

Lin Xinyi sighed lightly and motioned to the police officers to take down Tanaka Zhishi.

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

Officers took a sample of the blood spots from his fingernails and escorted him out of the villa and into a police car.

And Lin Xinyi finished his work and walked out of the villa.

Outside the villa, Miss Gray Yuan was standing there quietly, looking at him with an inquiring gaze:

"Well, I should have helped 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 in his heart, so he left the crowd and walked to Gray Yuanai's side, and whispered, "Thank you." ”

"Thanks for what..."

Miss Gray Plains replied coldly:

"It's just a matter of applying ready-made theories to forensic science research."

"It doesn't take much effort to write a paper at this level."

"And in addition to DNA methylation modification differences, I can also help you study the technical methods for screening WZ from multiple directions such as copy number variation, microRNA expression, and antibody library differences."

"If I need to, I can help you write a few more papers—"

"The first author writes your name, just use it."

At this moment, she is like a domineering president who has taken care of her boyfriend, and her tone and expression are so cold and stylish when she speaks.

"But—" suddenly took a turn of events.

Miss Gray Yuan suddenly changed from an awesome academic boss to a gentle and homely little wife:

"These days, remember to go home early."

"Huh?" Hearing Gray Yuan Wai suddenly say such a sticky word, Lin Xinyi was a little surprised.

"Don't think too much..."

"I'm not one of those clingy little ghosts..."

Gray Yuan Wai turned her head a little embarrassed, revealing her half-breed delicate and three-dimensional perfect profile:

"I asked you to come back early because I wanted you to learn the necessary knowledge from me."

"The paper has your name on it, but you have to understand the theory mentioned in it."

"Academic fraud must also be passed by one's own ability, otherwise when you meet peers who come to exchange academics, you will soon be exposed."

"So..."

Her cold little face showed a beautiful pink:

"Remember to come back early, student bio."

..............................

The next day, at noon, the Maori Detective Agency.

School is on holiday again today, and Conan is out of the cage.

But fortunately, the Mori family had no activity today, and Conan stayed honestly in the detective agency and didn't go anywhere.

Time passed peacefully.

Mori Kogoro finished his lunch, drank a few cold beers, and fell asleep at his desk.

Conan had just woken up from his nap and opened the bedroom door to the living room, wanting to lie on the couch and watch TV.

At this time, he suddenly discovered...

His little sister Lan was tiptoeing around the sleeping Maori Kogoro like a thief, pushing open the door and walking out.

"Sister Xiaolan?" Conan was wearing his pajamas, rubbing his eyes, and asked, "Where are you going?" ”

"Huh? Ke, Conan? Maolilan turned his head in a bit of a panic and was slightly relieved to see that it was Conan who appeared behind him.

"Shhh Maorilan made a silent gesture at Conan, making it very mysterious.

And Conan only then noticed:

His sister Xiaolan had already changed into that very formal suit and skirt at this time.

The slim hip skirt with a bright white shirt, thin stockings, and high heels looks quite a kind of mature charm of an urban beauty.

If you look closely, her white and red cheeks seem to be wearing just the right amount of light makeup.

Not surprisingly, this moving shape that is completely different from the usual school uniform makes the sleepy-eyed Conan children hungry all of a sudden.

"Ahem..."Conan swallowed his saliva and asked with some curiosity, "Sister Xiaolan, is there another case?" ”

He knew that Maolilan usually only changed into this very formal workplace dress when he needed to follow the forensic class to the police.

And this time, unlike what he thought, Xiaolan's answer was a little vague:

"No... I'm out for a bit of a thing. ”

"Something?"

Conan's eyes suddenly sharpened:

It's the afternoon of the holiday, Xiaolan avoids her family, what can she do when she goes out alone?

Going to the supermarket to buy groceries and groceries?

No, since Xiaolan gradually became obsessed with solving cases and studying, the work of purchasing daily necessities at home has been completely handed over to him and Maori Kogoro, two men who have "nothing to do" all day long.

So, is it to go shopping with the garden?

No, when Xiaolan and Yuanzi go shopping together, they won't dress so formally.

Not to mention, she also rarely wore light makeup and dressed up so brilliantly.

That being the case, that .... So what's the answer?

"Sister Xiaolan..."

Conan was apprehensive in his heart, and said with some concern:

"You can't go out on a date with someone this time, right?"

"Uh... Appointment? ”

Mao Lilan was slightly stunned and replied:

"Well, that's right, it's dating."

"Conan, you have to help me keep it secret, don't tell Dad!"

Conan: "......"

His little face turned green, and he couldn't help asking, "Who are you dating?!" ”

"It's—that's..."Mao Lilan thought for a moment, and said a little embarrassedly, "It's your new brother!" ”

"Don't tell Dad, let him know that I'm dating your new brother, he'll probably lose his temper."

As she spoke, without waiting for Conan to react, she closed the door with a smile and walked out.

Conan, who stayed in place, was still a little dazed:

"Brother Shinichi..."

"Oh, it turns out that Xiaolan is dressed up so beautifully, she is going out on a date with me!"

Conan breathed a sigh of relief, and then...

How is this possible!!

I'm Shinichi Kudo!!

Wait, dating Shinichi's older brother... Don't...

Xiaolan is talking about this "new brother", doesn't he mean me?

Conan's little heart pounded.

His faint worries that have never been dispelled, the terrifying scene he saw in the "Black Cloak Organization Exercise", and the analysis and reasoning of Miss Yuanzi's relationship with Xiaolan...

These shadows emerged one by one, completely occupying his mind at this moment.

Thinking of this, Conan's face became greener and greener:

"Lin Xinyi... You bastard! ”
