Chapter 19: Don’t Be Too Idle

Jiang Yuan took out the first fingerprint, which was only the front half of the fingerprint, and the position was relatively blurred.

Faced with such a fingerprint, Jiang Yuan's first thing to do was to determine which finger it belonged to.

After that, it was to process the fingerprint image.

Finally, it was to mark the feature points.

After Jiang Yuan obtained the fingerprint skill, he used it for a few times, and it just felt a bit familiar with it. Now the operation was very smooth.

The slightly blurred fingerprint image after being enlarged was constantly enlarged and reduced under Jiang Yuan's mouse, and the color level, brightness and light and dark were changed from time to time. At the same time, Jiang Yuan also kept marking the feature points.

Wang Zhong felt dazzled and couldn't watch it after a while.

PS is a software with very powerful built-in functions and a large number of shortcut keys to facilitate users to improve efficiency.

But for bystanders, if the user does not explain or explain, the bystanders will be dizzy after a bunch of shortcut keys.

Just like Wang Zhong's state at this time.

"Come on, I'll go back first." Yan Ge was even more bored sitting there, so he said hello and went back to his office to work.

Wu Jun naturally looked at Wang Zhong and smiled, "Little Wang, aren't you going back to work?"

"I'll watch for a while, learn a little, and then go back to work." Wang Zhong didn't quite understand Jiang Yuan's operation, but he knew that Jiang Yuan was now processing fingerprints.

This kind of operation, in fact, even if Jiang Yuan explained it to him in detail, he couldn't remember it, and even if he remembered it, he couldn't use it for a while.

Anyway, Wang Zhong just stared at it, and learned as much as he could.

At least, he can learn something now. In the past, Wang Zhong followed Yan Ge and had nothing to learn.

In the process of processing the image, Jiang Yuan marked 4 feature points. After completing this step, he chose a direction from another corner and marked 5 more feature points, saying: "These first, let's run it and see."

Wang Zhong felt dazzled, and before he entered the state, he saw that Jiang Yuan had already run the software.

In a moment, 20 fingerprints appeared in the candidate list.

Jiang Yuan eliminated them one by one and marked them again.

Wang Zhong soon became tired of watching.

For trace detection, fingerprint comparison is extremely boring.

This process is like a person looking for a twin of a hedgehog.

He can pull out 8 thorns first and compare them all over the world. If they don't match, he can pull out a few more thorns, or mix them with some of the previous 8, or form an independent team and continue to compare all over the world until they match, and then check whether all the thorns are the same.

There is an old saying: 8 and 8, 8 and 8, each one is different, hard and slender.

Jiang Yuan compared tirelessly for half an afternoon, and when it was time to get off work, he finally announced that the first fingerprint comparison failed.

"Go home." Jiang Yuan packed his luggage and prepared to get off work on time.

Wang Zhong was like a physics enthusiast, dazed and sleepy after listening to a lecture on theoretical physics for half an afternoon - he thought he should like it and be excited, but his body and brain thought he was wrong, so that he now doubted his own existence.

Jiang Yuan didn't care about that, went home to eat meat, and shared his award with his father.

"I just got to work and I won the award, not bad." Jiang Fuzhen was very happy. While saying this, he took out his mobile phone and called Aunt Hua, saying: "Do you know how much young people make now? Is 10,000 yuan a lot?"

"It should be quite a lot. Now we rent a two-bedroom apartment in our community for only 1,000 or 2,000 yuan. It depends on the decoration." Aunt Hua answered naturally: "The house I bought in the provincial capital a while ago only rents 3,000 or 4,000 yuan a month. In fact, it's not cost-effective..."

"I think so, but when we were farmers, 10,000 yuan was too much. Now I don't know. I just watch the money go into the account all day and don't know how much it is."

"You are Fuzhen, so it must be a lot."

"I heard from my son that he solved a case at work two days ago and was rewarded with 10,000 yuan. I was thinking, do all work units give so much in rewards now? Hahaha, it must be quite a lot..."

Aunt Hua's tone changed after hearing this: "Is there such a high reward for being a policeman?"

"I said that too, I haven't heard of it. But he solved a case from 20 years ago, which is called an unsolved case on TV."

"Hiss, that's amazing."

"Well, their leaders also praised him. I just wanted to ask, maybe the money has depreciated in the past two years..." Jiang Fuzhen laughed a few times and hung up the phone.

Jiang Yuan looked up at his father and said, "Don't you go to the vegetable market every day?"

"Just to confirm. You don't know how serious inflation is. By the way, I forgot to ask..." Jiang Fuzhen picked up the phone and replayed it.

After a short pause, a machine voice came from the phone: The number you dialed is in progress...

Jiang Fuzhen smiled affluently.

...

The next day

When Jiang Yuan arrived at the unit, he attacked the second fingerprint.

To no avail.

The third day.

Continuing from yesterday, to no avail.

The fourth day.

Jiang Yuan gave up the second fingerprint and started to compare the third fingerprint.

Compared with the previous two fingerprints, this fingerprint was also incomplete, but the details of the remaining part were relatively rich. It was equivalent to a hedgehog with healthy fur and plump prickles.

Jiang Yuan then compared more detailed parts.

Starting point, divergence point, small eye, small hook, junction point...

Jiang Yuan enlarged the fingerprint image, and only displayed a part of it on the screen. He moved the mouse gently and carefully outlined it.

Wang Zhong finished his daily work and ran over to watch as usual.

He stared at Jiang Yuan's operation, feeling that he could do it, but also that he couldn't.

It was like facing a physics problem. The formulas were all known, and it felt reasonable for him to write it this way, but if he wanted to say what he thought, his head seemed to be caught by the door.

Wang Zhong fell asleep again while watching.

It was not until he heard Jiang Yuan say "I got it" that Wang Zhong opened his eyes like a toad under a spell and asked, "Did you get it?"

"It should be this." Jiang Yuan pointed at the screen.

Wang Zhong leaned over in surprise, and while Jiang Yuan was checking again, he nervously compared it.

"How is it?" Jiang Yuan asked politely.

"It seems... I got it?" Wang Zhong didn't know how to answer. For him, it is very common to match the fingerprints of a new case, but it is not common to match the fingerprints of an old case, even the old fingerprints of the current case.

If Wang Zhong himself matched, he would probably jump up and shout a few times.

But Jiang Yuan obviously did not mean to celebrate.

For him, the fingerprints of this case cannot be said to be simple, but it is not difficult either.

This is actually normal. Don’t look at what Wang Zhong said about the series of thefts. Even if it is a series of thefts, it is still not comparable to the serious injury case with great social impact like the "Liu Yu injury case". The fingerprints involved were carefully screened by experts in Qinghe City at least.

And this "highway service area series of oil theft cases" does not sound advanced at first. Although it involves a wider range, the trace inspections involved in the investigation are mainly those of the county bureau. Although there may be experts in a certain county bureau, the case may not be assigned to the hands of the experts.

For example, in Ningtai County, Wang Zhong is doing it, and he can’t do it. He just can’t do it.

"This guy seems to be in prison." Jiang Yuan opened the suspect's information and saw a traditional prison photo with small eyes, flat nose, thin mouth, slanted eyebrows.

"He was imprisoned a month ago. There is no conflict in time." Wang Zhong took a quick look, breathed a sigh of relief, and looked at the case again, saying: "Look, he was fighting with someone in a nightclub and caused minor injuries. The money he spent in the nightclub was probably earned by stealing oil."

Jiang Yuan asked: "What about now?"

"Call Captain Huang. With the evidence, it is estimated that several gang members can be brought out." Wang Zhong said with a flat mouth: "If Captain Huang heard that you solved another case, he would be very happy."

Jiang Yuan smiled: "I'm a little free recently, and there are no other cases..."

"You can't talk about this." Wu Jun, who was originally leisurely, heard Jiang Yuan's words, and his face changed immediately.

Jiang Yuan was stunned for a moment, and then smiled embarrassedly: "Forgot, you can't say too free, right?"

"Don't say this word..." Wu Jun sighed, lowered his head and unconsciously glanced at his mobile phone, as if it would ring at any time.
