There are few people who play cars, especially racing cars, that are not modified. Lu Yao's friends who usually love to play with cars, which one of them didn't spend hundreds of thousands, or even millions, on changing cars.

It can be said that there is more than one vehicle modification car that is supported by the No. 3 race. But after all, the market for vehicle modification is relatively niche, so most modified cars are actually repair shops.

In the entire Haizhou City, there are only a few capable people who can change cars. Sanyo Vehicle Repair Shop is one of the best among them.

Of course, Lu Chuan didn't want to modify the vehicle, the middle-aged man in the photo he paid attention to. More precisely, it was the middle-aged man who compared the middle finger of the scissorhands.

Of course, a man's fingers, no matter how distinctive, will not be as attractive as a little girl's green jade fingers.

What attracted Lu Chuan's attention was the fingerprint of the middle finger of this named Wang Qi. There's always a sense of déjà vu.

As a criminal police officer on the current investigation, Lu Chuan's intuition to solve the case may be a little worse, but his intuition for fingerprints is definitely far superior to others.

All the fingerprints that Lu Chuan has studied, I can't say that I remember every line, but there will always be a sense of familiarity.

In the eyes of the fingerprint identification and analysis criminal police, fingerprints are a person's appearance. With raised ridges and extended lines, each fingerprint has its own characteristics.

Just as there are always a few people in a crowd who look alike, so do fingerprints. In the photo, the man in the middle is comparing his scissor hands, just in time to be able to take the fingerprint of his middle finger clearly.

"Third brother, give me this photo to use."

"No problem, just take it." Lu Yao has the impression that this photo is a photo of the top three and the modder after a competition, which is not important.

Besides, even if it is very important, if Lu Chuan wants it, there is no problem.

"You guys play first, I'll come when I go." Lu Chuan took down the photo and left the crowd. When it comes to work, Lu Chuan naturally has a subconscious habit of vigilance.

More than ten meters away, Lu Chuan took out his mobile phone and retook the whole photo. The focus was on the reproduction and collection of the fingerprints of the middle-aged man.

Of course, due to the pixel problem of the photo itself, the fingerprints collected are relatively blurry, but it should be usable to deal with it.

With Lu Chuan's intermediate fingerprint collection skills, this difficulty was not difficult for him, and within a few minutes, the photo was re-hung on the wall.

Of course, racing can't just race. But in the follow-up field, Lu Chuan did not participate.

This is probably another advantage of going to the Public Security University, the baptism of ideological education is very thorough, and Lu Chuan is not contaminated with the bad habits of ordinary rich children.

Looking at the time, it was almost midnight, and there was no need to process fingerprints now. Lu Chuan just felt that the middle-aged man's fingerprints had some familiarity, and in a cautious and responsible manner, he collected his fingerprints.

When you have time, deal with it and compare it in the system. After all, most of the cases that Lu Chuan came into contact with were big and important cases, and it was estimated that there was nothing good about the fingerprints that he could familiarize himself with.

The next day of the Spring Festival, the Chenguang community was very lively. On a sunny morning, every household came out to paste Spring Festival couplets.

The custom of pasting Spring Festival couplets has different times in different places. Some are the day before Chinese New Year's Eve, some are early in the morning on Chinese New Year's Eve, or in the evening.

There are also early posters on the first day of the new year. The custom here in Haizhou City is to post Spring Festival early in the morning on Chinese New Year's Eve. In the impression of the Lu family, even when they were the poorest in the past, they would post Spring Festival couplets during the Spring Festival.

Even, sticking Spring Festival couplets will extravagantly use white flour and water to make a paste and act as a glue. Commonly known as white batter.

This work, I don't know when it started, it was Lu Chuan who started it. Maybe it's my year in college, maybe it's my sophomore year.

Lu Chuan doesn't remember very clearly, it seems that suddenly one year, many things in the family, his father let go.

"Dad, the Spring Festival couplets are pasted, I'll go set off firecrackers." The Spring Festival couplets are not only pasted with pairs outside the door, but also small parts such as well-springs, safe entry and exit, and joy when looking up.

As for the flocks of chickens and ducks that Lu Chuan saw when he was a child, he can't see them now. If there is, it is estimated that it can only be pasted on the kitchen board.

The Spring Festival breakfast is simple, no different from usual. Lunch and dinner are combined into one, and the whole family eats together.

According to the rules of the Lu family, this meal was not made by someone, but the daughters-in-law of each family showed their skills.

Even some of the men showed their hands in the same way. Other people play mahjong, fight landlords, and smoke and chat.

There was laughter and laughter in the community hall. It was divided into three large circles. The generation led by Lu Jianguo, in the middle of the hall, pushed pai gow.

The second generation of the Lu family of Lu Qiqiang's brothers, in the northeast corner, plays mahjong. Lu Chuan has more than a dozen third-generation children, some of whom play games, some smoke, and some watch videos.

As for Lu Chuan...... in the chat.

"Is your dinner ready?"

"No, my parents are busy." Shen Yan was wearing cartoon bear pajamas, lying lazily on the bed, staring at the phone screen with big eyes and a smile.

"Do you want to come to my house for dinner?" Lu Chuan's heart trembled, knowing that Shen Yan was joking, but he still had a strange feeling.

"Okay, I'll have two drinks with my father, but I don't know where to live if I drink too much?"

"I only have two bedrooms, where do you want to live?" As soon as she sent it out, Shen Yan felt her cheeks burn, and hurriedly withdrew the message.

"Don't withdraw, I've seen ......" In the past two months, the chat between the two has been quite bold.

"Hmph, see it, see it, don't talk to you, I'm going to get up."

"Just getting up?" …… The seventh day of the Lunar New Year. Survey Office. Lu Chuan went to work early, mopping the floor, wiping the table, and making tea, all in one go.

The anthurium by the window did not dry up because of the passage of the holidays. On the contrary, after a week of wild growth, the leaves become more emerald green and the anthurium becomes more delicate.

The tall figure looks like the arrogant Shen forensic doctor. Click. Lu Chuan took a photo of the anthurium and sent it to Shen Yan.

"Lu Chuan, morning, Happy New Year!" Liu Guodong is always the second to come to the office after Lu Chuan came.

"Happy New Year, Master!" During the Spring Festival, the current survey office gathered once. It was organized by Liu Guodong and went to Wang Kai's house to pay New Year's greetings.

The current survey office is not like the action group, because it was established late, and Wang Kai is at the veteran level. Other action groups also met for the New Year, but at the home of the retired old leader.

"Do you have a morning meeting today?" Lu Chuan put down the anthurium and handed the enamel jar to Liu Guodong.

"Today is a heart-to-heart meeting, and it is estimated that it will take a little longer." During the Spring Festival, Haizhou City can be described as calm.

Of course, there were cases, but there were no fatal cases. For the criminal investigation detachment, as long as there are no homicides, the rest is not a big deal.

After Liu Guodong left, Lu Chuan turned on the computer and started the day's work. In fact, there is not much work in the field survey recently.

If there is no homicide, there will be no scene, and there will be no attendance for the investigation. As for the cases in various districts and counties, they naturally have their own people to investigate.

If they all point to a few people in the criminal investigation detachment, they can't do it if they are too busy to die. What Lu Chuan wanted was the familiar fingerprint found in the No. 3 arena seven days ago.

Now that I'm idle, I'm just going to take care of it and see if there's anything to gain. The remade fingerprint photo is a little blurry and needs to be denoised to improve the clarity.

This is the first time that Lu Chuan has used photographs and inadvertently taken fingerprints for identification and analysis. When he was in college, Lu Chuan heard from his teacher that some cases were solved through fingerprints extracted from ordinary photos.

Unexpectedly, Lu Chuan himself met one. The progress of the pre-processing was very fast, and in less than ten minutes, Yang Sen and Lao Bai had just stepped into the office door, and it was over.
