The system reward for Song Kun’s homicide case has finally arrived.
To Lu Chuan’s surprise, the system has undergone a mode upgrade.
Previously, he could only passively accept system rewards, but now Lu Chuan can choose the rewards himself.
The virtual screen in his mind has also beco more vivid.
A window that could move up and down according to Lu Chuan’s thoughts appeared.
"Criminal Investigation Technology: Basic, Interdiate, Advanced Criminal Psychology, Basic, Interdiate, Advanced Investigation Interrogation Techniques, Basic, Interdiate, Advanced Criminal Imaging Techniques..."
"Security Technology: Basic, Interdiate, Advanced Network Security Technology, Basic, Interdiate, Advanced Security Engineering Design, Basic, Interdiate, Advanced Security System Maintenance..."
"Forensic Technology: Basic, Interdiate, Advanced Criminal Photography, Basic, Interdiate, Advanced Trace Identification, Basic, Interdiate, Advanced Docunt Identification..."
The entire list included all specialties related to criminal investigation.
Each specialty had several sub-skills, often numbering in the dozens.
Upon a rough glance, there were about a hundred skills.
Among all the skills, those Lu Chuan already possessed were marked in red, selectable skills were in blue, and unselectable advanced skills were in gray.
This system upgrade gave Lu Chuan a feeling similar to choosing a major after taking the college entrance examination.
Within the Public Security University’s teaching frawork, the major categories in the system were essentially equivalent to different departnts in schools.
The skills within were different professional directions.
In addition to these, there were branches of forensic dicine.
"Forensic Clinical dicine: Basic, Interdiate, Advanced Injury Assessnt, Basic, Interdiate, Advanced Disability Assessnt, etc."
"Forensic Anthropology: Basic, Interdiate, Advanced Skeleton Identification Analysis, Basic, Interdiate, Advanced Skull and Facial Reconstruction, etc."
There were also branches like Forensic Psychiatry, Forensic Toxicology, Forensic Pathology, Forensic Entomology, and others.
Beyond these, there were many other types of skills.
For example, abilities that enhance combat effectiveness like shooting and fighting.
These also divided into basic, interdiate, and advanced levels.
"Please choose the type of reward, Host."
"1. An interdiate skill card."
"2. An interdiate skill upgrade card."
Should he directly choose an interdiate reward, or upgrade an interdiate skill to advanced?
Lu Chuan didn’t even think about it; skill mastery is about quality, not quantity.
After the system upgrade, the rewards were abundant, and even if Lu Chuan solved a case every day, mastering them all in his lifeti seed challenging.
Moreover, since acquiring the system, Lu Chuan had been involved in about ten cases, big and small.
Among them, there were four or five homicides, but the rewards were all basic and interdiate skills.
This shows that acquiring advanced skills is quite challenging.
This ti, with the opportunity to upgrade an interdiate skill to advanced, Lu Chuan wouldn’t miss it.
"System, select the interdiate skill upgrade card."
"Interdiate skill upgrade card selected, please choose the skill you wish to upgrade."
"1. Interdiate Fingerprint Collection Skills, 2. Interdiate Skeleton Identification Analysis Skills, 3. Interdiate Fingerprint Identification Analysis Skills."
These are the three interdiate skills Lu Chuan currently possesses, and he can only choose one of them for an upgrade.
This ti, Lu Chuan didn’t hesitate at all and directly selected Interdiate Fingerprint Identification Analysis.
"Upgrading Interdiate Fingerprint Identification Analysis Skills... Please wait."
Swish!
As the system’s notification sound fell, knowledge and techniques about fingerprint identification analysis rushed like a tide into the depths of Lu Chuan’s mind.
The interdiate fingerprint identification analysis ability led to significant discoveries in the girl skin case in the wheat field.
The fingerprints collected from the victim’s skin completely locked down the suspect.
This ti, the upgrade from interdiate to advanced gave Lu Chuan a feeling of qualitative change.
The techniques regarding fingerprint identification analysis were now completely transparent before Lu Chuan’s eyes.
Fingerprint identification analysis is both a systematic discipline and a field with significant individual differences.
Theoretical knowledge and practical experience are crucial in enhancing fingerprint identification analysis ability.
The results analyzed by different fingerprint identification experts also vary.
The fingerprint identification conducted by frontline investigation criminal police, like those in the High-tech Zone Criminal Investigation Team, should be considered the lowest level.
They can only perform rough identification and comparison of clearly collected and standardized fingerprints; they struggle to succeed with fingerprints that exhibit slight distortion, blurriness, or loss.
A higher level includes people like Yang Sen and Old Bai, who have so talent and relatively rich experience.
While conducting cri scene investigation part-ti trace examination, they can make so analytical adjustnts to defective, distorted, or blurry fingerprints before identification.
The success rate is generally good, but they can only rely on luck with severely missing, distorted, or blurry fingerprints.
Even higher are people like Liu Guodong, who barely participate in the fingerprint battles organized by the provincial departnt, always ranking at the bottom and usually finding only one or zero fingerprints.
As Liu Guodong himself said, he’s just there to fill out the expert database.
Each of the ten or so Criminal Investigation Teams in the province needs at least one mber they can present, after all.
It’s like how a novel website fills its library – those who get in may not be capable, but those who don’t certainly aren’t.
Even more advanced trace examiners can be called fingerprint identification experts, at least recognized as such within the province.
For example, the Tianzhou City Criminal Investigation Team’s trace examiners are professionals, not part-tirs; their sole job is fingerprint identification.
They are among the best in the province, achieving at least two or three successful comparisons in each fingerprint battle.
Beyond that, there are the experts from the provincial departnt, who have the ability to participate in nationally organized fingerprint battles by the ministry.
Their combat effectiveness can be described as off the charts.
As for what "off the charts" ans, Lu Chuan didn’t know before, but now, after receiving the advanced fingerprint identification analysis skill, he has gained so understanding.
Generally speaking, fingerprint identification analysis refers to the comparison of the identity of the fingerprint.
You are given a fingerprint, preprocess it, mark feature points, compute data, and then compare it within the system.
The specific thods derive from various identification thods extended from ten-finger fingerprint classification, such as Qingdao-style single-finger fingerprint analysis and Chongqing-style single-finger fingerprint analysis.
Advanced fingerprint identification analysis not only includes single-finger analysis thods but also linked-finger analysis thods.
Additionally, it includes analyses related to the fingerprint owner themselves.
For instance, you can determine the fingerprint owner’s age, lifestyle habits, physical condition, residential area, and other information through fingerprints.
These are things Lu Chuan had heard of but never seen before.
In advanced fingerprint identification analysis, there are detailed operation thods for these judgnts and verifications.
For example, in determining age, a person’s palm size is smaller when they are young, and the fingerprint lines appear finer.
By examining the thickness and density of the lines, you can determine whether the person is a child or an adult.
Through data comparison, you can lock onto an approximate age range.
