Li Zemin casually clicked on the new message notification, then clicked again, and two fingerprints appeared quietly on the left and right sides of the screen. However, unlike the fingerprints that Jiang Yuan had identified as the same last time, the left fingerprint this time could be said to have reached the sky.

Li Zemin couldn't help but rub his eyes and exclaimed, "Has it become like this?"

"The lake is mainly noise, once it's processed, it's not that exaggerated," Jiang Yuan said simply.

Li Zemin clicked his tongue and leaned in to carefully examine the left side of the screen.

After a while, Li Zemin raised his head with a sound and clicked agree on the right side of the new message. He also identified the same based purely on the pattern and lines of the fingerprints, but he hadn't used this method for some time.

Looking up again, Jiang Yuan's number of successful matches had already become "2", as 11 experts had already identified the same.

"Old man," Li Zemin patted his forehead and looked around. Jiang Yuan and Zhonghua Yan had already disappeared, and Jiang Yuan's computer was wailing.

Li Zemin quickly left the office and found a few guys smoking on the shaded balcony.

"Taking a break?" Li Zemin walked up to them with a smile.

"Want one?" Jiang Yuan handed Li Zemin a cigarette.

A quick look at bit.ly/3iBfjkV will leave you more fulfilled.

"Sure." Li Zemin happily took the cigarette and said, "The image processing you did was pretty impressive. Image processing is so good, yet you're still doing our job of trace examination, wasting time."

"What a waste? Those who do image processing are all fake," Qian Mingyu, a trace examiner from Miaohe County, said. He was extremely impressed with Jiang Yuan because he had just identified the same match for a 515 case. He continued, "I don't mean that image processing is bad for breaking cases, but our fingerprints are the king of evidence for breaking cases. If your fingerprints are good, there's no need to waste time on image processing. Plus, those who do image processing stare at the screen all day, which can easily damage their eyes."

Everyone present laughed when they heard this.

It was hard to say which one, fingerprint examiners or image processors, would damage their eyes first.

"What case did Jiang Yuan just break? I was in a rush just now and forgot to check," Li Zemin asked. He had been thinking about soft Zhonghua cigarettes just now and didn't pay attention to the details.

"It was a fingerprint from an arson case in Fumin Building in Changyang City," Jiang Yuan replied.

"No wonder it was an arson case," Li Zemin nodded and asked, "Did you match the suspect?"

"He's already in prison for the arson," Jiang Yuan answered.

Li Zemin was stunned and laughed, "Then it looks like there's no problem."

Jiang Yuan agreed and handed him another cigarette.

"Don't you want one?" Li Zemin asked as he smoked.

Jiang Yuan shook his head, "Someone said that smoking mouthpieces also absorb nicotine, so I don't smoke anymore."

"Then you're wasting the cigarettes you bought," Li Zemin said regretfully as he took a big puff.

"That way, there will be more cigarettes for everyone to smoke. It's also a good excuse to get some fresh air," Jiang Yuan said.

"That's the right way to think. You're a clever one," Li Zemin said admiringly as he looked at Jiang Yuan. After being a detective for a long time, he had learned how to handle interpersonal relationships. He admired two types of people the most: those who were good at their jobs and those who were good at handling people and things. Jiang Yuan had both when he handed out the Zhonghua cigarettes.

Jiang Yuan returned to his office after smoking two cigarettes with the others. The sound of his computer whining had stopped.

The computer had never done such hard work before, and it was now panting. When Jiang Yuan began to move the mouse, the fan spun wildly, as if the two outer shells were shouting, "Can you hurry up?"Jiang Yuan ignored the sound of the computer and focused on annotating the characteristic points on the processed fingerprint image.

This time, he was dealing with a badly distorted blood fingerprint from a lake, probably taken from a glass or somewhere else, with some reflection still visible. It was very weak overall when viewed with the naked eye.

However, after image processing, it was barely presentable. Even so, it would still be difficult for an ordinary trace examiner to mark it.

Image enhancement was similar to a beauty camera. The basic logic was to turn a fingerprint that was dark and unclear into a clear white one, just like turning a dark and unclear face into a clear white one. However, forensic image enhancement was more specialized and had specific requirements for the distortion and changes of the lines.

When annotating the processed image's characteristic points, one had to avoid some special points and surfaces, so Jiang Yuan was particularly careful.

Li Zemin rubbed his ears and looked at Jiang Yuan, who occasionally made a noise as if he hadn't recovered from the noise of the computer. Although the noise was indeed annoying, even if the director came, they would still have to endure it. Of course, the most direct solution would be to change the computer or provide a dedicated location. Perhaps someone had already complained and even called the director directly.

Li Zemin felt that Jiang Yuan didn't care about this matter too much. Everyone was serving the people, and if the machine was exhausted, it meant that the person's efforts were deeper. As long as something could be produced, it might be better to invite the director over to observe.

Just as he was thinking about it, the section chief of the fingerprint post, Yang Ling, arrived in the office.

The fingerprint post of the Provincial Department was a scientific research institution with only a few personnel. It mainly played a role in uploading and issuing information, and activities such as fingerprint battles were also organized and arranged by the fingerprint post.

Yang Ling, the head of the fingerprint post in the Provincial Department of Shannan, was in her thirties and a high-achieving graduate of the Criminal Police College. She had both technical ability and social skills and easily commanded a group of highly myopic middle-aged and elderly trace examiners.

When she entered the office, Yang Ling smiled and approached Jiang Yuan, asking softly, "Do you have a moment, Professor Jiang?"

Using the title of professor was very polite.

Jiang Yuan looked up and saw Yang Ling. He smiled back but hesitated for a moment before saying, "I'm sorry, can you wait for me for a minute? This one seems hopeful."

"I understand." Yang Ling nodded immediately. During the fingerprint battle, reading fingerprints was a big deal, but she didn't need to rush.

Out of politeness, Yang Ling walked around the table and stood beside Jiang Yuan.

From her position, she could also see the fingerprint image on Jiang Yuan's screen.

The two images on the left and right were indeed quite similar.

Yang Ling's expression suddenly became much more serious.

Each case here would touch many people's hearts if it were outside. Even at the Provincial Department, where various cases were seen daily, Yang Ling dared not be the slightest bit careless.

Moreover, despite the fact that the Provincial Department held a fingerprint battle every few months, bringing together dozens of fingerprint experts to work day and night for half a month, ultimately solving more than 50 cases, it was still considered a remarkable achievement.

On average, each fingerprint expert would handle only one case.

And anyone whose salary had been averaged out should know what it meant to handle only one case per person: many experts would go home empty-handed."Even if it takes a specialist 14 days of hard work, there wouldn't be so many pending cases accumulated in the Provincial Department.

Correspondingly, Yang Ling wouldn't dare to interfere with Jiang Yuan's work, even if she wanted to.

'Here Comes the Defender'

Jiang Yuan checked left and right, and finally opened the original blood fingerprint to take a closer look.

After about two or three minutes, Jiang Yuan submitted the "identification of sameness" and breathed a sigh of relief. He looked at Yang Ling and said, "Sorry, I just finished the last step."

"It's okay, it's okay." Yang Ling waved her hand repeatedly and glanced at Jiang Yuan's screen.

At this time, the number of experts who agreed with Jiang Yuan's "identification of sameness" increased rapidly in the lower right corner of his screen.

Many people noticed that Yang, the head of the fingerprint department, had come and naturally took a look at the newly updated message.

And after reading the new message, it was only natural to agree with Jiang Yuan's "identification of sameness".

On the wall in front of the office, the projector displayed the results of the battle rankings, and Jiang Yuan jumped to second place, only one result behind the first-ranked Zhu Huanguang.

"You just asked to see me, is there something you need?" Jiang Yuan looked at Yang Ling.
