The whole city is my old attack

"what are you saying?"

Two hours later, after seeing off X who had seen the old photos, Chu Feng received a call from the DNA laboratory:

"Mr. Chu, I'm very sorry, I really couldn't extract anything from the tableware you sent, not only DNA, not even a fingerprint."

Chu Feng was silent for two seconds. X's hands were bandaged. It was understandable that he didn't have fingerprints, but it was too strange not to mention any DNA. Spoons, chopsticks...all were put in his mouth.

"Are you sure it's the tableware I sent over?"

"Yes, Mr. Chu. I'll take a video right here for you to confirm."

"Okay. Thank you." Chu Feng hung up the phone and immediately contacted the restaurant staff.

"Yes, yes. Mr. Chu, we followed your instructions throughout the whole process. We never touched the tableware. We ensured that it was sent to the appraisal office with zero contact, and it was never cleaned."

After learning about the situation, Chu Feng clicked on WeChat, and the people from the DNA testing institute had already sent a live video.Chu Feng glanced at the leftovers in the bowl, it was indeed the tableware he and X had eaten.

Chu Feng: "Are you sure - you can't find any trace?"

DNA Laboratory: "Yes. Mr. Chu, I'm very sorry. Fingerprints and DNA were extracted from your set of tableware, but the other's set...was very clean, and nothing was found."

It's almost like no one has ever used it.

Chu Feng stared at the video. X's used tableware was placed on the test bench and packaged. From the naked eye, there was still some soup left in that bowl, which was less than 1/2 of the small bowl. It couldn't be said to be very clean. Like all the cutlery that normal people finish eating in restaurants.

But it's too clean to mention a key thing.

Chu Feng was inexplicably thinking at this moment that he was investigating the matter of 13-year-old Xiao Xie. At that time, the old criminal policeman took the dismemberment case from 16 years ago and said:

"Definitely a veteran, the scene is too clean."

At that time, Chu Feng was silent, and he was the only one left in the whole world. One person knew that Xie Shiyu was only 13 years old at that time, and it was his first crime.

,

In Chu Feng's mind, he recalled the events of noon. He didn't leave for a second during the meal, and X was under his nose from the beginning to the end.

Just like two normal people, he ate until the end, and sent the tableware to the DNA laboratory. The laboratory easily extracted his DNA and fingerprints, but X had nothing.

The absence of fingerprints could also be interpreted as X's hand being bandaged.

But why is the DNA missing?

After hanging up the phone, Chu Feng repeatedly played the real detailed video sent by the DNA testing institute.

—There must be something that seems normal but is actually wrong, allowing X to erase the potential DNA traces under his nose without knowing it...

,

Chu Feng compared the differences between the two sets of tableware.

The last thing he ate at noon was scrambled eggs with mushrooms. The bottom of the bowl was stained with golden egg liquid from the mushrooms, and there were some slight oil stains and sauces.

X finally drank a bowl of rose fish milk soup at noon today. X had already drank two bowls before, and it was the third bowl in the end. Some of them may not be able to drink, and about 1/3 is left in the bowl.

soup……

Chu Feng stared at the small bowl of leftover soup, thinking of X's preference for dishes.This guy likes to eat the same food as Xie Shiyu.

Xie Shiyu still likes to drink the rose fish milk soup from this restaurant, and he will drink two or three bowls every time.Chu Feng remembered that every time Xie Shiyu came here to eat, he always ended up with a bowl of rose fish milk soup.

——Chu Feng suddenly figured out something, and memories of going out to eat with Xie Shiyu came back one time after another. Almost every time, Xie Shiyu would drink a bowl of soup after meals.

This is not something worth noting, and many people may have such eating habits.But Chu Feng began to doubt today, whether Xie Shiyu finished the soup every time, or every time like this, deliberately left some in the bowl.

When eating, spoons and chopsticks may leave DNA in the mouth. If the last thing you drink is a bowl of soup and you deliberately don’t finish it, then just shake the spoon and chopsticks into the soup for a little bit, and all traces will disappear. up.

——At the end of the meal, scoop a bowl of soup, drink it with a spoon until about 1/3 is left, put a small spoon into the soup, and stir into the soup with chopsticks to make sure there is nothing left. Then put the chopsticks on the chopstick rest on the dining table. If the restaurant has a spoon rest, put the spoon back again, and say to the eating companion with a smile:

[I am full.let's go. ]

All movements are very natural.When I went out to eat, there was some undrinkable soup left in the bowl. It was a very common thing. It was impossible for normal people to doubt it.

And the DNA left in the mouth melted into the soup without a trace.

Therefore, Xie Shiyu will never leave DNA when eating out.

Chu Feng sat alone in the bedroom and suddenly laughed.It's like discovering another little secret.He had had dinner with Xie Shiyu for so many years and watched it thousands of times...

It wasn't until today that he really realized that Xie Shiyu had such a little habit, and he thoroughly understood all the reasons behind this little habit.

Xie Shiyu is not a normal person.All the reasons behind these seemingly ordinary little habits are to eliminate traces to the greatest extent.

Chu Feng understood the judgment of the criminal police back then. The most people in this world are ordinary people. Most people choose to be ordinary good people, and a small number become ordinary bad people. Even if they embark on the road of crime, they are still ordinary people. people.

-Start to do bad things, half-knowledge, flustered, through continuous dealings with the police, -observe and learn step by step, understand how the police investigate cases, and then gradually acquire sufficient awareness of anti-reconnaissance, and become - an old hand.

This is the common learning mode of human beings.The difference is that some people are learning the right things, while others are learning the crooked ways.But no matter what you learn, this is a skill you have learned and cultivated the day after tomorrow. Most people will feel mentally and mentally exhausted if they want to maintain a counter-reconnaissance state all the time.

But Xie Shiyu was not, he seemed to be a kind of innate instinct, a natural reaction engraved in his bones, and he was born with this material.

God had given him a dark cloak of invisibility, allowing him to walk unhindered.

But he took off, put on a casual vacation shirt, held someone's hand, and went to the sunniest tropical seaside to spend his honeymoon.

,

"Hello, Mr. Chu."

"Hi, I'm sorry, this DNA test is temporarily canceled," Chu Feng said.

"...Are you sure you want to cancel?"

"Yes." Chu Feng: "For the time being."

Because of this little soup habit, the plan failed this time.It is impossible to extract X's DNA from the tableware, and it cannot be identified. Scientifically, it is still impossible to determine who X is.

But in retrospect, people who can have such a habit can carry this instinct in their bones like Xie Shiyu even if they have amnesia... In a sense, it shows that X is...

Chu Feng raised his hand and pinched the center of his eyebrows, dissuading himself from indulgent thoughts.

His current state of mind is really unbearable anymore - he will be happy again, and he will collapse again.I can only lower my expectations as much as possible, and if the scientific results come out, X is not Xie Shiyu, so it won't be too uncomfortable.

"Mr. Chu, let us cancel it for you first, and we will also dispose of the tableware. Your fingerprints and DNA data extracted from it will also be eliminated. Please rest assured."

Chu Feng: "Yes."

"Mr. Chu, do you still need to continue to extract DNA from the clothes you just sent? Or do you need to—and cancel?"

Chu Feng paused for a moment: "This will not be cancelled. Is there any result now?"

Laboratory personnel: "Because there are too many things, we are still extracting samples one by one. We may have only screened about half of the clothes, and no DNA has been found for the time being."

To verify the DNA, you need to collect X's DNA and Xie Shiyu's DNA, and compare the two to see if they are the same person.

Although X's DNA collection is a bit difficult, X is a living person after all, and if the tableware project failed this time, there will always be another chance.And Xie Shiyu...

Chu Feng has already sorted out all kinds of old things of Xie Shiyu and sent them to the DNA laboratory, asking the laboratory to find out if there is any DNA of Xie Shiyu left on it.

Now it seems that hope is very slim. If Xie Shiyu wiped out his DNA in this way even when eating, he would be very careful in his daily life.

The most important thing is that after Xie Shiyu left for two years, Chu Feng would regularly wash his old clothes.Even if Xie Shiyu was relatively relaxed at home and would not deliberately erase the traces, but... the old things that have been scrubbed for two years, it is really difficult to leave any residues.

Laboratory: "Don't worry, Mr. Chu, we will do our best to find it. If there are any traces left, we will extract them."

"Okay." Chu Feng: "It's troublesome."

The laboratory he was looking for was very trustworthy, as long as the money was in place, everything would be fine.The best point is that this computer is closed. Even if the DNA fingerprint information is extracted, it cannot be transmitted to other places. Once deleted locally, it will be completely shredded to protect the privacy of the authenticator.

This is something that Chu Feng values ​​very much. He will never allow such important DNA information of Xie Shiyu to fall into the hands of others.Just in case, he also placed people in the laboratory. If Xie Shiyu's DNA was extracted, it must be destroyed as soon as possible after the comparison.

"How long will it take to extract the DNA?"

"Mr. Chu, it will take at least 24 hours, because the clothes you sent are really... There are several large boxes, and we need to inspect each one..."

Chu Feng nodded: "En. Please hurry up."

"-Certainly."

,

108-story hotel.

After returning from Chu Feng's house, X was sitting in the bedroom, holding in his hand a whole package of old photos brought back from Chu Feng.

He looked down and overlooked the city under the floor-to-ceiling windows, small people as big as ants, and cars as fast as beetles, flowing continuously, day and night.

X - Zhang, - Zhang, scroll down, most of the photos are single photos of young Chu Feng, wearing brand-name sweatshirts and sneakers.

Sometimes there will be a photo with another little boy in the photos, who is a little taller than the young Chu Feng, and the clothes can't be seen from the brand, but the price can't be seen either.

X observed carefully - took off the shoes, the little boy's shoes were a bit tattered, observed carefully, there was a little bit of degumming on the back of the soles, it can be seen that this little guy's family background is not very good.

One has a good life, the other has a hard life, and their family backgrounds are very different, but because they entered the same class in elementary school, their relationship gradually improved. Then the little boy invited Chu Feng to his house to observe the swallows.

X sits in a wheelchair, sketching a big outline of what's going on.He began to search for Chu Feng's solo photos, and finally, he pulled out—Zhang Xiao Chufeng...

It seems to be participating in the sports meeting of the second grade. Chu Feng and his childhood sweetheart husband are participating in the two-person three-legged weight-carrying.

The competition calls for a bag filled with all the textbooks for the semester.Then the two ran on three legs.

The game begins—

Several photos were taken in a row... X pinched the photo and looked at it with a magnifying glass:

Little Chu Feng carried a heavy blue schoolbag with a string of letters embroidered on it:

adidas.

,

"Hi, hello, this is the DNA laboratory, may I help you?"

X—holds the phone in one hand, and in the other—holds—a plastic bag containing a few strands of hair he just plucked:

"Send a sample. Do a DNA test."
