The fingerprint of Bai Shengsheng was neat and proper, like a young girl from a deep boudoir.

Jiang Yuan knew, however, that this seemingly perfect fingerprint had looked like an African American comedian just a few hours ago. It had taken him a long time and LV4-level image enhancement skills borrowed from the Provincial Department's Criminal Investigation Division to restore it to its current appearance, which could be considered an epic-level transformation, like turning an orange cat into a ragdoll cat.

And to count the person behind it, the fingerprint of Bai Shengsheng would also turn black and red.

Jiang Yuan did a routine feature point marking and scanned 300 fingerprints without a match before stopping.

This fingerprint was quite special.

It was taken from the collar behind the victim's neck, and with the technology of several years ago, the technician on the scene needed to have a considerable level of skills to do so.

However, the technician who did the scene investigation at the time was still unable to match this fingerprint.

Jiang Yuan stared at this seemingly transformed fingerprint and fell into deep thought.

He could imagine that when the killer, the owner of this fingerprint, tried to strangle the victim, the strength of his fingers would be pushed to the limit. Similarly, the victim must have tried his best to resist the attacker's attack in the last moment, tightening his muscles and skin.

Therefore, this was a fingerprint that deformed in both directions on soft material, and the marked feature points could not be made. The next step should be to adjust the deformation. Based on the lines and structure, some artificial adjustments should be made, which were basically done by trying to find a match.

Some fingerprints could take several months for a forensic examiner to match, and some could take several years of continuous attempts.

Jiang Yuan had previously used the trial-and-error method to match fingerprints, but that was because he had enough relevant information and conditions to do the testing.

However, Jiang Yuan couldn't find any room for adjustment no matter how he turned this fingerprint over.

It's not that it couldn't be adjusted, but because the force and deformation were both variable, the difficulty of trying to match it had greatly increased. Moreover, the technician who did the scene investigation was obviously a master in fingerprint analysis, and Jiang Yuan could only imagine that the methods he could think of were probably the ones the other party had tried.

But if he didn't use conventional methods, which direction should he take to win?

It was not easy to play with a fingerprint that was only about one square centimeter in size, turning it over for months or even years, and thinking of a new trick that no one had thought of before.

Matching this fingerprint was difficult.

During Jiang Yuan's contemplation, the system's semi-transparent interface silently appeared in front of him.

...

Mission: Persistent Pursuit.Mission content: During the fingerprint battle, do your best to solve multiple cases. Current progress (8*2)...

...

From the content, 8*2 should be the total number of cases and the number of cases assigned.

Jiang Yuan's thoughts were interrupted for a moment, but he quickly refocused and glanced at the fingerprint. He couldn't help but think: actually, there's no need to consider the entire fingerprint.

This fingerprint was taken from the neck, and the curvature of the neck, which may not be noticeable under normal circumstances, may be more prominent when being strangled.

Jiang Yuan simply cut out a small piece from the fingerprint and marked it.

In other words, he abandoned most of the fingerprint that was painstakingly taken by the forensic team.

Only the most stable small piece.

This small piece of fingerprint, when carefully analyzed for its features and scanned into the software, gave Jiang Yuan hope.

He is now using the Qingdao-style single-finger fingerprint analysis method to process this small piece of fingerprint.

The Qingdao-style single-finger fingerprint analysis method and the Chongqing-style single-finger fingerprint analysis method have their own advantages and differences. One obvious difference is that the Qingdao-style divides fingerprints into 68 categories, while the Chongqing-style divides them into 24 categories.

This difference makes the Chongqing-style easier to start with, while the Qingdao-style is more suitable for manual brushing of large quantities.

After brushing a few fingerprints in a few seconds, Jiang Yuan sat up straight and stared at a fingerprint, carefully comparing it.

Li Zemin, who was next to him, noticed that his own work had stopped and watched Jiang Yuan's operation.

He was a little interested in learning from Jiang Yuan.

However, Jiang Yuan had no intention of hiding his work.

Fingerprint comparison is a very personalized job, especially when dealing with difficult fingerprints. After reaching this stage, judgment is more important than skill.

Skills can be learned, but judgment involves more things.

Li Zemin was still thinking about Jiang Yuan's thoughts when he saw Jiang Yuan move the mouse and select "identify as the same."

"Is that a match?" Li Zemin was surprised.

He knew that Jiang Yuan was comparing the assigned cases.

Jiang Yuan took a sip of tea and cleared his throat before saying, "Take a look and see if it's a match."

"Right, right." Li Zemin turned back to his screen and heard the sound of notifications coming in one after another.

It was a beautiful morning, and many people had notifications for new messages.

When they saw it, many people clicked to take a look.

Jiang Yuan's name was like a cool cup of coffee poured over everyone's heads.

Comfortable.

Eye-catching.

Full of energy.

Li Zemin carefully looked at the fingerprint image several times, and then slowly clicked "agree" under "identify as the same."Turning his head, Li Zemin looked at Jiang Yuan in surprise and asked, "So fast? Is image processing really that useful?"

Jiang Yuan smiled. How could he answer? Should he say that he was fast because he was really skilled and already a provincial expert? Or should he say that image processing technology needed to be combined with fingerprint technology, and his image enhancement skills were only at the level of a weak provincial expert?

"Want a cigarette?" Jiang Yuan took out a pack of Zhonghua cigarettes.

"Let's go." Li Zemin was indeed diverted by the topic and immediately got up to follow Jiang Yuan.

In front of the building, there was an ancient-style pavilion where several smokers from the Provincial Department were smoking nicotine. When they saw Jiang Yuan and Li Zemin coming, they smiled amiably.

Jiang Yuan also nodded and took one side of the pavilion with Li Zemin, each smoking a Zhonghua cigarette.

One of the middle-aged smokers saw the soft Zhonghua cigarettes in Jiang Yuan's hand and immediately frowned. Ignoring his colleagues' glances, he said in a dissatisfied tone, "The conditions are so good? What are the units below thinking these days? They are all..."

"I'm from Jiang Village." Jiang Yuan didn't let the other party finish his sentence and handed him a Zhonghua cigarette in a very Jiang Village manner.

The middle-aged man who spoke still maintained his serious frown and took the cigarette in a daze.

The expressions of the other people were better, but they were also quite surprised to receive the cigarettes.

Li Zemin also couldn't stand the attitude of the Provincial Department people too much. Looking at this scene, he couldn't help but smile.

"From Qinghe?" The middle-aged man who took the cigarette confirmed.

"Yes, from Jiang Village in Ningtai County." Jiang Yuan calmly lit his cigarette and took a puff in front of the smokers.

Looking at the soft Zhonghua cigarettes being spit out without any value, several people showed a look of pity, but thinking of Jiang Village's identity, they didn't bother to comment.

"Jiang Yuan!" A police officer with a tightly fastened collar walked out of the Provincial Department building with extreme seriousness.

Jiang Yuan and the others recognized him when he approached and smiled, "Director Liu."

The one who came quickly was Liu Jinghui, a fourth-level senior police officer known for his reasoning skills in the Provincial Department.

He walked into the pavilion, looked at the middle-aged men smoking, reluctantly nodded, and greeted, "Director Hong."

Turning his head, Liu Jinghui asked, "I just saw the police report. Did you match the fingerprint on Wu Long's collar?"

From Liu Jinghui's description, it could be seen that he was highly concerned about this case. He not only set up related reminders but also had a clear understanding of the victim's situation.

Without hesitation, Jiang Yuan said, "I matched the fingerprint on a murder case. The victim was found on Wu Long Mountain."

"That's it, that's it..." Liu Jinghui's fingers pointed twice, and his emotions visibly rose.

His colleagues from the provincial department looked at Jiang Yuan curiously, surprised, "Did you win a lottery or something? Are you here to participate in the fingerprint battle?"

"Yes. I'm from Qinghe." Jiang Yuan replied with the term he was just asked.

Everyone understood, and the middle-aged man who spoke first laughed, "You have a temper, but that's to be expected from someone from Jiang village. Sorry about earlier, I thought you were a young person who came here to slack off, but I didn't expect you to come for the fingerprint battle. It's rare to see such a young fingerprint expert."

"Plus, he's won three lotteries." The person next to him gave a thumbs up.

Li Zemin chimed in, "That's right, three of them."

"Three what?"

"He's won three lotteries." Li Zemin held up three fingers.

Everyone was amazed.

The middle-aged man took a puff of his just lit cigarette and smiled, "I really couldn't recognize Mount Tai. Nice to meet you, I'm Hong Wanjun. My brothers call me Hong Qi, Hong Qi from Hong Qi Gong. They say I have a temper, which sounds good as 'jealous of evil,' but bad as 'offending people everywhere.'"

Jiang Yuan shook hands with him and exchanged WeChat numbers.

Liu Jinghui, who was next to him, had accumulated enough emotions at this point and took advantage of a gap to say, "Jiang Yuan, you have to come with me."

"Where to?" Jiang Yuan was puzzled.

"To investigate the Wu Long's wild tree. This tree is definitely not a simple case of throwing a corpse in the wilderness." Liu Jinghui spoke confidently, "I think there are hidden motives behind this tree, and it's likely a series of murder cases..."

"There's a body?" Jiang Yuan was surprised, thinking he didn't see that in the case briefing.

Liu Jinghui said seriously, "No body, it's possible that other bodies were thrown in better places. But from the handling of this body, the murderer has rich experience, and the discovery of this body is also quite coincidental. It was discovered by a lost hiker and not on the regular patrol route of the mountain rangers, and there are no conditions nearby for companionship..."

"So now that we've won the lottery, shouldn't we go catch the suspect first?"

"It's been too long." Liu Jinghui shook his head slightly, "You should be able to see for yourself that the suspect who won the lottery has been released from prison for six years and has disappeared without a trace. He also participated in a murder case during that time. It's difficult to find someone like that directly. However, investigating the Wu Long's wild tree has opened up a new direction for investigation. I invite you to join me and form a new investigative team...""Liu Chu, I'm currently participating in a fingerprint competition." Jiang Yuan interrupted Liu Jinghui's words. He didn't like Liu Jinghui as a person, and in his view, reasoning was neither mysterious nor reliable. Liu Jinghui's approach of reasoning first and then gathering evidence was even less accepted by him. Under such circumstances, Jiang Yuan naturally didn't want to join any special task force with Liu Jinghui.

However, Liu Jinghui looked at Jiang Yuan with affection in his eyes and said word by word, "I'll wait for you!"
