Rebirth of the God-level Xueba

the next day.

When Yang Rui came to the Stockholm Police Station, there were twice as many police officers in the office area on the second floor.

Some police officers with high-level epaulettes also appeared inside. They stood with Sherwood and chatted easily.

In the position near the door, several reporters were holding cameras, looking for angles.

Yang Rui was a little surprised by this, but not surprising.

Although I don't know whether it was the reporters who attracted the high-level police officers, or the high-level police officers attracted the reporters, as long as there is a taste of fresh meat, it is not surprising whether it is a mess or a mess.

Yang Rui’s yellow skin was recognized by the reporters without introducing them. They were not many, but they still blocked the way, and asked: "Mr. Yang Rui, I heard that you are going to use high technology to challenge the Marle case, is that true? ?"

There are not many reporters and there will be no rushing and noisy situations, but fewer reporters means that questions are more difficult to answer.

Yang Rui looked up at Sherwood, Director Sherwood nodded slightly, not knowing whether he nodded in greeting or agreed with Yang Rui to answer questions.

Yang Rui didn’t think so much anymore. He said, “It can’t be said to be a challenge. We just want to provide the police with more tools to handle cases so that they can have more choices when investigating. The PCR machine is a tool. It is still the Stockholm police who challenged the Marler case. We are just logisticians."

This answer can be regarded as humble. The policemen who understand English nodded silently, and their attitude improved.

If Yang Rui said in a big way to replace the police, they would naturally not be happy.

"Mr. Yang Rui, some people say that the Marle case was completed by two murderers. What do you think of this?" A reporter looked like a boxer and asked questions with urban tales.

Yang Rui said calmly: "We are just tools. Our PCR machine will give as much information as possible. As for how to interpret the answers from this information, that is the job of the police."

Yang Rui's thinking today is very clear. He is here to promote the PCR machine, not to fight the police.

In fact, his idea is just the opposite. He hopes that more police and police stations will use PCR, that is, use DNA identification technology. On the other hand, Yang Rui doesn't want PCR to be regarded as a pure criminal investigation technology by the society. It insults the value of PCR too much. It is as nonsense as saying that X-rays are pure medical equipment.

"Mr. Yang Rui, how much confidence do you have in today's test results?" The reporters found that they couldn't dig out some drastic data from Yang Rui, and reluctantly returned to the topic.

Yang Rui said, "I have 100% confidence."

"Why?" The reporter finally grabbed a topic and asked quickly.

Yang Rui shrugged and said, "The accuracy of comparison with DNA is very high. Through PCR amplification, the chance of test failure is very small."

After stopping, Yang Rui felt that what was said was not quite clear, and said: "I describe it this way, it may be easier to understand. If the police use DNA to judge the killer, there will be no two people with the same DNA in the 6 billion people in the world. Not only that, but judging from probability, in the recent thousands of years of human history, the DNA of all human beings born will not be completely the same. Therefore, with such accuracy as the basis for judgment, I have a hundred percent confidence."

"Will there be man-made mistakes?" A professional reporter said sharply: "How can man-made mistakes be avoided?"

Yang Rui smiled, looked at the reporter, and said: "I am a scientist. In the realm of science, I will try my best to achieve the goal. Maybe you can ask God to judge your request."

Everyone smiled softly.

The reporter just didn't hear it, and said: "What do you mean, there will still be human errors?"

If it were in a normal question and answer format, Yang Rui should probably answer "of course" at this time, and then explain in detail.

However, in a foreign country, Yang Rui became more sensitive. He took a little more thought. What would happen if a reporter reported PCR out of context?

The first encounter was the challenge of the court.

Unlike later generations, in the present of 86 years, no country has yet to admit DNA evidence. In other words, conviction with DNA requires disputes.

Yang Rui cannot leave such a handle in public.

At least, he could not leave such a handle as the inventor of PCR and as a well-known expert in genetics.

Thinking of this, Yang Rui waved his hand without hesitation, and said: "What we are discussing today is not the issue of human error, but the test results. How about we finish this work first?"

He seemed to question the people below, looking at the Chief Sherwood.

The chief of police is also a very politicized figure. He noticed Yang Rui’s evasive answer and immediately thought of the corresponding results. He said in a flash: “Let’s take a look at the test results now. If the test results meet our expectations, the Stockholm police may take action. This technology is used in the detection of the Marler case. Everyone, please let me."

The people in the office stepped aside and let Yang Rui and Sherwood walk into the room where the PCR was placed.

"Introduce it." Yang Rui nodded to Huang Mao and Tu Xian.

"How to introduce?" Huang Mao and Tu Xian both had stage fright.

"Just talk about what you did in the past two days." Yang Rui said, turning around and smiling at the camera.

Tu Xian and Huang Mao pushed for a moment, and Tu Xian stood up and said in English: "Yesterday, we collected the DNA of police officers. In addition, we got a bunch of hair with skin sacs. After that, our test was to judge the hair. Who is the owner of this."

The policemen who took part in the test smiled, and some raised their hands.

In front of the media, the Swedes have also become more lively.

But that's it.

"Now, the police officers, please give the answer to Chief Sherwood, and we will announce our answer." Tu Xian finished, as Yang Rui arranged in advance, a photo of a bunch of hair and photos of several police officers who participated in the test. , Posted on the whiteboard in front of him, just like a crime drama in later generations in Europe and the United States.

The reporters soon discovered that this method was extremely intuitive and took pictures.

The police leading the team also handed the envelope with the name to Sherwood.

Sherwood didn't open it immediately, and said first, "Mr. Yang Rui, please let me know how you compare."

"Tu Xian." Yang Rui shouted.

Tu Xian coughed, took out two rolls of paper from the bottom of the PCR machine, and said: "The principle of the PCR machine is actually to extend DNA. Now we have made an image of DNA. As you can see, there are two images of DNA. Consistent..."

As he said, he opened the two volumes of drawings and hung them on the other whiteboard next to them.

The two specially printed drawings are full-color, colorful blocks, bumps and bumps on a line, forming a peculiar pattern.

"This is drawing A." Tu Xian pointed out another one, and said, "This is drawing B. As you can see, drawing A and drawing B are the same..."

"What about the other pictures? Let's look at the inconsistencies." Someone from the reporter called out.

Tu Xian glanced at Yang Rui, benefited from it, and unfolded all the other drawings.

Without his special explanation, everyone realizes that other drawings are not the same.

"It's well done." A female reporter praised her.

Tu Xian was bored and said, "This is automatically generated by the machine."

"Tu Xian, read the owner of the hair you confirmed." Yang Rui reminded.

Tu Xian gave an "Oh", lowered his head to check, and said: "We confirm that the owner of the hair is Ackerman."

What he said was plain, with a little less passion.

Fortunately, those who came today were all graphic journalists, and they didn't care about his passion, so they turned their attention to Sherwood again.

Sherwood smiled slightly, opened the envelope in front of him, took a look, and then turned to everyone.

Ackerman's name, printed in swashes, was shown to everyone.

In the office area, there were bursts of surprised sounds.

"Sergeant Ackerman, please stand up." Chief Sherwood called again.

I saw a Swede who looked like a tall Swede, smiling and raising his hand.

"Sergeant Ackerman, was it your hair that you left yesterday?"

"It's mine~www.wuxiaspot.com~ Ackerman laughed twice.

The reporters gave soft applause, but the Swedish police officers present were rather dull.

Yang Rui curled his lips and thought, if this were to be played in the United States, it would have been an uproar.

"Director Sherwood, say that, you will adopt new technology in the Marle case, right?" A reporter raised the point at this time.

Sherwood nodded slightly and said: "Not only in the Marle case, we will also use PCR technology in many cases."

Yang Rui was taken aback, this was a bit beyond his expectation.

However, from Yang Rui's point of view, this is just a good thing. He is not afraid of technology being tested.

Suddenly, Yang Rui became excited again. In his lifetime, he could see the technology he developed for the detection of serial homicides. It was also a rare and handsome thing.
