Rebirth of the God-level Xueba

Marle is an ordinary Nordic town.

It has a gentle and clean river, but it is frozen for six months of the year, and broken ice is often floating in the rest of the time. It had a beautiful fitness trail, wide and straight, covered with beautiful shock-absorbing planks, but three people died on it.

Marle is most famous for its lithographs, which can be traced back to the Viking era, but no one wants to see these lithographs. They may be works of art or antiques. However, it was not until someone's blood soaked the land that a camera came to this cold city.

Yang Rui jumped out of the car, crunching snow beneath his feet.

Yang Rui looked far away and could see the distant snow-capped mountains and the houses at the foot of the mountain.

"It's a very wide place." Yang Rui exclaimed: "There can be a distance of 100 meters between a house and a house."

"Swedes like to live farther. We don't like hearing neighbors' voices, whether talking or shooting." Officer Ackerman closed the car door heavily and followed Yang Rui.

Yang Rui’s PCR technology recognized Ackerman’s hair, which made him instantly become a fan of PCR technology. Not only that, he also found the information to read it by himself-the Swedes are not a social nation, they love to do it the most. The thing is to squat in the corner of the world and study your own gadgets.

"There are 874 permanent residents in Marle." Ackerman asked, "Where do you want to start?"

"We must first delineate the residents of the town. If it is not done by people from outside the town, we can directly collect the residents' DNA. To be on the safe side, please proceed under our guidance." Yang Rui explained that the content has actually been communicated before. , Just repeat the description.

Ackerman just needs this kind of repetition.

PCR is a new thing for everyone, everyone has to repeatedly confirm, so as not to make the wrong steps, affect the results-in fact, Yang Rui emphasized this point.

The residents of the town were notified in advance and soon gathered.

This may be unthinkable in the United States. The Americans in a town cannot be expected to gather on time in a regular manner, but the Swedes can, whether it is a month in advance or a day in advance, as long as the time is confirmed and confirmed, Will get everyone.

The descendants of these Viking pirates were reticent, but appeared at the assembly place on time as if they were preparing to board the ship.

"Isn't it unexpected?" Huang Mao walked behind Yang Rui and said, "Look at these Swedes, they all look ordinary. Who can guess, there can be a murderer inside."

"It can't be said to be ordinary, many people are over 1.9 meters tall, right." Yang Rui shrugged.

"Similar to you." Huang Mao looked up at Yang Rui enviously, and said, "How do you say you are as tall as a Nordic. No, it's taller than many Nordic people."

"God gifted." Yang Rui said sincerely.

Huang Mao laughed.

"For a while, ours will use a cotton swab to stir in your mouth, so that it won’t damage your body. This is the latest technology and is used to do the necessary tests..." A senior police officer took the microphone and said The residents introduced the situation, and his voice was plain, as if he was talking about an ordinary trivial matter.

The residents also seemed to be listening to an ordinary trivial matter.

Instead, Yang Rui stood below, picked up his red flag camera, and when the first resident started sampling, he desperately pressed the shutter.

In an age when there were less than 30 photos in a roll, his shutter quickly couldn't move.

Yang Rui laughed to himself, opened the back cover of the camera, carefully put away the film, and said to Jing Yulan next to him: "From now on, these will be formal historical materials."

"Historical materials?" Jing Yulan carried LV's bag, wearing a wide-brimmed lady hat, and a sunglasses on the bridge of her nose to prevent snow blindness. From a distance, she was already a beautiful girl at the forefront of fashion. .

Yang Rui put her hand on her waist, hugged and loosened it lightly, and said with a smile: "The first use of PCR in human history to handle a case is of course historical data. This must be in the museum in the future."

"You think it's important, what if others don't?" Jing Yulan joked with a smile.

Yang Rui thought for a moment, and said, "Then I will build a museum by myself." Yang Rui answered very clearly, making Jing Yulan a little dazed.

Kaka.

In an instant, Yang Rui pressed out another roll of photos.

Huang Mao, Tu Xian and others supervised and assisted the entire sampling process.

Sampling is the most important step. For PCR itself, there are few mistakes, but once a sampling error occurs, it is all over.

Yang Rui looked relaxed, but in fact he was nervous.

If the murderer is not among the residents, if the sampling is wrong, if there is a problem with the operation of the technician... what he wants is big news, not a big scandal.

However, this is how you do things. You have to accept acceptable risks. If you can’t accept them, end them early. If you can accept them, you can’t regret it.

Marle's journey soon ended.

Yang Rui returned to Stockholm and just started to sort out the samples. She was called into the office by Director Sherwood and asked: "Mr. Yang Rui, how long will I receive the results? I mean, how long will the murderer be identified."

"If you are lucky, tomorrow, if you are not lucky, it will take two or three days." Yang Rui said: "Our PCR machine is not enough to do all the samples at once."

"That is to say, it takes three days to make a complete sample? Only three hundred per day?" Director Sherwood calculated and asked, "Can you find more?"

"In fact, we can only do less than 200 samples per day, and we don't need to do all the samples. We can exclude some."

"Huh? It can be ruled out, but won't people be missed? Mr. Yang Rui, you have to know that we want to pass the PCR technology with the judge. It takes some work. If we make a mistake the first time, it will be very difficult to pass it. It's difficult."

Yang Rui smiled and said: "It won't be missed. We only exclude women when we are sure. In fact, we only exclude women."

"Isn't a woman committing the crime?"

"Well, because the murderer's DNA is male." Yang Rui briefly explained the relationship between the X and Y chromosomes to Sherwood, and said: "If the genome project is completed, we can exclude more things. At present, it is the safest. The method is to exclude women, and then start the test from young and middle-aged residents. At the same time, a sample of women is taken to avoid accidents."

If the human genome project is completed, or if we can learn more about human genes, we can get the murderer’s DNA and draw a fairly detailed face, such as race, skin color, age, etc., which are all easy to get. Nose or rosacea, curly hair or straight hair, there are signs to follow.

However, the 1986 Human Genome Project is still in its infancy, and there is hardly anything useful, at least not something that can be used immediately at this time, Yang Rui said.

Sherwood is not going to ask for more scientific details. The information Yang Rui told him has already made Sherwood quite satisfied. He smiled and said: "This is the best way. I have talked with the judge. They will learn about this technology independently. , But I believe there is no problem..."

Although the concept of DNA has appeared as early as the 1950s, DNA as evidence is a novelty all over the world, and the judicial system of every country needs a process of acceptance.

Yang Rui had an idea earlier. Hearing Sherwood's words, he couldn't help saying: "I have a proposal."

"Yep."

"You may be able to use some relatively definite small cases as examples of PCR applications. If you pass it once, can you solve the problem of judicial determination?" Yang Rui used uncommon English words to talk to Sherwood with difficulty.

He doesn't need the Marler case to be the first case of PCR. Such a first has limited support for news~www.wuxiaspot.com~ What he needs more is a solid case.

If you can perfectly prove the value of the PCR machine, and then publicize that PCR solves complex cases, it might be more meaningful to Yang Rui.

Sherwood was a little surprised, and said: "Do you want to use a PCR machine to solve a few cases first?"

"Yes. If you can't arrange funding, we can provide trial services."

"No. If it's just a small case, the cost is not a problem." Sherwood obviously doesn't care about the expenditure of tens of thousands of kronor, and just pondered: "You are very confident in the PCR machine."

"Of course." Yang Rui laughed. DNA identification is known as the king of physical evidence. For a long time, the judicial systems of various countries have worshipped DNA as a god.

Sherwood did not have the urge to worship God for the time being, and agreed to Yang Rui's suggestion. From his point of view, it was always good to be able to choose a more secure way.
