The system reward for Song Kun's murder case has finally arrived.
What surprised Lu Chuan was that the system had a mode upgrade.
The previous model where he could only passively accept system rewards has now become a model where Lu Chuan can choose rewards independently.
The virtual images in my mind also became vivid.
A window opens that can move up and down with Lu Chuan's thoughts.
"Criminal investigation technology: junior high school advanced criminal psychology, junior high school advanced investigation interrogation technology, junior high school advanced criminal imaging technology..."
"Security prevention technology: junior high school advanced network security technology, junior high school advanced security engineering design, junior high school advanced security system maintenance..."
"Forensic identification technology: junior high school and advanced criminal photography, junior high school and advanced trace identification, junior high and advanced document identification..."
The entire list includes all majors related to criminal investigation.
Within each major, there are several or more than a dozen subdivided skills.
After a cursory look, there are probably hundreds of skills.
Among all the skills, Lu Chuan's existing skills are marked in red, optional skills are marked in blue, and non-optional advanced skills are marked in gray.
This system upgrade gave Lu Chuan the feeling of choosing his major again after the college entrance examination.
Under the teaching system of the Public Security University, the major classifications in the system are actually different school departments.
The skills inside are different professional directions.
In addition to this, there are branches of forensic science.
"Clinical Forensic Medicine: Identification of the degree of injury at the junior high and advanced levels, identification of the degree of disability at the junior high and advanced levels, etc."
"Forensic Anthropology: Skeleton identification and analysis for junior and senior students, skull facial reconstruction for junior and senior students, etc."
There are also all branches of forensic psychiatry, forensic toxicology, forensic pathology, forensic entomology and so on.
In addition to these, there are many other kinds of skills.
For example, the ability to improve combat effectiveness such as shooting and fighting.
They are also divided into junior, middle and senior levels.
"Please host choose the type of reward."
"1. An intermediate skill card."
"2. An intermediate skill upgrade card."
Should I directly choose an intermediate reward, or upgrade an intermediate skill to a high level?
Lu Chuan didn't even think about it. It's not too much effort but finesse.
After the system upgrade, the rewards provided are dazzling. Lu Chuan solves one case a day. It is estimated that it will be very difficult for him to learn them all in his lifetime.
Moreover, since the time-travel system was established, Lu Chuan has participated in the investigation of more than ten cases, large and small.
There are four or five murders, but the rewards obtained are all primary and intermediate skills.
It can be seen that it is relatively difficult to acquire advanced skills.
This time, given the opportunity to upgrade an intermediate skill to a high-level skill, Lu Chuan would not miss it.
"System, select the intermediate skill improvement card."
"The intermediate skill improvement card has been selected, please host select the skills that need to be improved."
"1. Intermediate fingerprint collection skills, 2. Intermediate skeleton identification and analysis skills, 3. Intermediate fingerprint identification and analysis skills."
These are the three intermediate skills that Lu Chuan currently masters. Lu Chuan can only choose one of these three skills to upgrade.
This time, Lu Chuan did not hesitate at all and directly clicked on the intermediate fingerprint identification analysis.
"Upgrade your intermediate fingerprint identification analysis skills...please wait."
brush!
The system prompt tone fell, and the knowledge and skills about fingerprint identification and analysis flooded into the depths of Lu Chuan's mind like a tidal wave.
The ability of intermediate fingerprint identification and analysis allowed Lu Chuan to make a major discovery in the case of the girl's human skin in Mai Langzhong.
The fingerprints collected from the deceased's skin completely identified the suspect.
This time, the intermediate skill was upgraded to advanced, giving Lu Chuan a feeling of qualitative change.
Regarding the skills and methods of fingerprint identification and analysis, Lu Chuan did not hide anything in front of him.
Fingerprint identification analysis is not only a systematic major, but also a major with huge differences in personality improvement.
Theoretical knowledge and practical experience are the keys to improving fingerprint identification and analysis capabilities.
The results analyzed by different fingerprint identification experts are also different.
In the High-tech Zone Criminal Police Brigade, the fingerprint identification performed by front-line detectives should be the lowest level.
It can only be said that a rough identification and comparison of collected fingerprints with relatively clear and standardized shapes will be difficult to successfully identify and analyze fingerprints that are slightly deformed by pressure or are blurred or missing.
At the next higher level are people like Yang Sen and Lao Bai, who have some talents and relatively rich experience.
On-the-spot inspection and fingerprint inspection can carry out certain analysis and adjustment on some defective, deformed and blurred fingerprints, and then conduct identification.
The success rate is generally good, but for some fingerprints with serious defects, serious deformation, and serious blurring, you can only try your luck.
At a higher level are people like Liu Guodong, who can barely participate in the fingerprint competition organized by the provincial department. Of course, he is at the bottom of the list and can only win one or zero fingerprints at a time.
In Liu Guodong's own words, he enriched the expert pool.
There are more than a dozen criminal investigation detachments in the province, and each detachment must have one who can take it out.
Just like a novel website filling a library, it may not work if you get in, but it will definitely not work if you can't get in.
With more advanced fingerprint inspection, one can be called a fingerprint identification expert, at least in the province, one can be called that.
For example, the Tianzhou City Criminal Investigation Detachment's trace inspection is a professional job, not a part-time job. The job content is only one task, fingerprint identification.
They are basically at the forefront in the province. In every fingerprint battle, there are at least two or three successful results.
There are also more advanced ones, namely several experts from the provincial department, who have the strength to participate in the national fingerprint competition organized by the ministries and commissions.
Combat power can be described as explosive.
As for the explosive method, Lu Chuan didn't know it before, but now he understands it after receiving the advanced fingerprint identification and analysis skills.
Usually, fingerprint identification analysis refers to the identity comparison of fingerprints.
Give you a fingerprint, perform corresponding preprocessing on the fingerprint, mark feature points, calculate the data, and then compare it within the system.
The specific methods are various identification methods extended from the classification of ten-finger fingerprints, such as Qingdao-style single-finger fingerprint analysis and Chongqing-style single-finger fingerprint analysis.
Advanced fingerprint identification analysis includes not only single-finger fingerprint analysis methods, but also multiple-finger fingerprint analysis methods.
In addition to this, there is some analysis of the owner himself through fingerprints.
For example, fingerprints can be used to determine the age, living habits, physical condition, living area and other information of the fingerprint owner.
These are things that Lu Chuan has only heard of before, but has never seen.
In advanced fingerprint identification analysis, these judgments and verification analyzes have detailed operation methods.
For example, when judging age, the palm area of a person is smaller when he is younger, and the fingerprint lines appear thinner.
By the thickness and density of the lines, you can tell whether the person is a child or an adult.
After data comparison, the approximate age range can be locked.
