[BL, MTL] The Whole City is My Old Attack

Chapter 95: DNA Identification

"What did you say?"

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

"Mr. Chu, I'm very sorry, but I really can't extract it from the tableware you sent. Nothing, not just DNA, not even a fingerprint."

Chu Feng was silent for two seconds, X's hand was tied with a bandage, so it's understandable that he didn't have any fingerprints, but it's too strange not to mention any DNA, Spoons, chopsticks...all put in the 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 contacted immediately Restaurant staff.

"Yes, yes. President Chu, we will follow your instructions throughout the whole process. We have never touched the tableware. We have ensured that it has been sent to the appraisal office with zero contact and has never been cleaned." After understanding the situation, Chu Feng clicked on

the Wechat, the people from the DNA testing institute have 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 traces?"

DNA Testing Office: "Yes. Mr. Chu, I'm very sorry. Your fingerprints and DNA were extracted from that tableware, but the other party's...very clean, what? None found."

It's almost as if no one has 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 case of 13-year-old Xiao Xie. At that time, the old criminal policeman took the dismemberment case from sixteen years ago and said, "He is 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 looked back at the events at noon. He didn't leave for a second during the meal, and X was under his nose from beginning to 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 actually something is wrong, causing 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, smile and say to the eating companion: [I'm 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 suspect that the

DNA left in the mouth would melt into the soup without a trace. no 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 eaten with Xie Shiyu for so many years and watched it thousands of times...

Until today, he really realized that Xie Shiyu had such a little habit, and 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. "Hi, hello, President Chu."
