Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 95 Advanced Skills

The system reward for Song Kun's murder case finally arrived.

To Lu Chuan's surprise, the system has undergone a mode upgrade.

The previous mode where he could only passively accept system rewards has now become a mode where Lu Chuan can choose rewards independently.

The virtual picture in my mind also became vivid.

A window opened that could move up and down with Lu Chuan's thoughts.

"Criminal investigation technology: junior middle and advanced criminal psychology, junior middle and advanced investigation and interrogation technology, junior high and advanced criminal imaging technology..."

"Security 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 school and advanced document identification..."

Throughout the list, all majors related to criminal investigation are included.

Within each major, there are several or more than a dozen subdivided skills.

After a quick 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 advanced skills that are not optional are marked in gray.

This system upgrade gave Lu Chuan the feeling of choosing a major again after the college entrance examination.

Under the teaching system of Public Security University, the major classifications in the system are actually different colleges and departments.

The skills inside are different professional directions.

In addition, there is a branch of forensic science.

"Clinical Forensic Medicine: Junior High School and Advanced Degree of Injury Identification, Junior High School and Advanced Level of Disability Identification, etc."

"Forensic Anthropology: Skeleton identification and analysis for junior high school and senior high school, skull reconstruction for junior high school and advanced level, etc."

There are also all branches of forensic psychiatry, forensic toxicology, forensic pathology, forensic entomology, etc.

Besides these, there are many other kinds of skills.

Such as shooting, fighting and other combat power enhancement capabilities.

It is also divided into junior high school and high school.

"Please host to choose the reward type."

"1. An intermediate skill card."

"2. An intermediate skill upgrade card."

Should I choose an intermediate reward directly, or upgrade an intermediate skill to advanced?

Lu Chuan didn't even think about it, he was more skilled than he was.

After the system is upgraded, there are a lot of rewards available. Lu Chuan solves one case a day, and it may be very difficult to learn all of them in his lifetime.

What's more, since time travel has the system, Lu Chuan has participated in the investigation of more than a dozen large and small cases.

There are four or five murder cases, but the rewards are all primary and intermediate skills.

It can be seen that the difficulty of acquiring advanced skills is relatively large.

Lu Chuan would not miss this opportunity to upgrade an intermediate skill to an advanced skill.

"System, choose an intermediate skill improvement card."

"The mid-level skill improvement card has been selected, please select the skill that needs 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, and Lu Chuan can only choose one of these three skills to upgrade.

This time, without the slightest hesitation, Lu Chuan directly clicked on the middle-level fingerprint analysis.

"Upgrade the intermediate fingerprint identification and analysis skills... please wait."

brush!
The system prompt sounded, and the knowledge and skills about fingerprint identification and analysis poured into the depths of Lu Chuan's mind like a sea tide.

The ability of intermediate fingerprint identification and analysis allowed Lu Chuan to make a major discovery in the girl's skin case in Mai Lang.

The fingerprints collected on the skin of the deceased completely locked the suspect.

This time, the mid-level skills were upgraded to high-level, which gave Lu Chuan a feeling of qualitative change.

The skills and methods of fingerprint identification and analysis were not concealed from Lu Chuan's eyes.

Fingerprint identification analysis is not only a systematic specialty, but also a specialty with great differences in personality improvement.

Theoretical knowledge and practical experience are the key to improving the ability of fingerprint identification and analysis.

The results analyzed by different fingerprint identification experts are also different.

The criminal police brigade of the high-tech zone, the fingerprint identification of the front-line criminal police cameos, should be the lowest level.

It can only be said that a rough identification and comparison of the collected relatively clear and standard-shaped fingerprints is difficult to identify and analyze successfully for slightly deformed or blurred or missing fingerprints.

At a higher level are Yang Sen and Lao Bai, who have some talent and rich experience.

The current survey and part-time trace inspection can continue to analyze and adjust some defective, deformed, and blurred fingerprints, and then carry out identification.

Generally speaking, the success rate is not bad, but for some fingerprints that are seriously missing, deformed, and blurred, you can only try your luck.

The ones at a higher level are those like Liu Guodong, who can barely participate in the fingerprint competition organized by the provincial department.

In Liu Guodong's own words, he enriched the pool of experts.

There are more than a dozen criminal investigation detachments in the province, and each detachment must have one that can be taken out.

Just like the fact that a novel website fills a library, those who get in may not be able to get in, but those who can't get in are certainly not.

A more advanced trace inspection can be called a fingerprint identification expert, at least in the province.

For example, the trace inspection of the Tianzhou City Criminal Investigation Detachment is a professional, not a part-time job. The job content is only one, fingerprint identification.

In the whole province, it is basically a front-running existence. In every fingerprint battle, there are at least two or three fingerprints that are successfully compared.

There are even more advanced ones, namely a few experts from the provincial department, who are capable of participating in the national fingerprint battle organized by the ministries and commissions.

Combat power can be described as explosive.

As for the method of exploding the watch, Lu Chuan didn't know it before, but now that he has received advanced fingerprint identification and analysis skills, he understands it.

Usually, the identification and analysis of fingerprints refers to the identity comparison of fingerprints.

Give you a fingerprint, preprocess the fingerprint accordingly, mark the feature points, calculate the data, and then compare it in the system.

The specific method is various identification methods extended from ten-fingerprint classification, such as Qingdao-style single-fingerprint analysis and Chongqing-style single-fingerprint analysis.

The advanced fingerprint identification analysis includes not only the single-fingerprint analysis method, but also the joint-fingerprint analysis method.

In addition to this, there is some analysis of the owner himself via fingerprints.

For example, the age, living habits, physical condition, living area and other information of the fingerprint owner can be judged through the fingerprint.

These were things that Lu Chuan had only heard of before, but had never seen.

In the advanced fingerprint identification analysis, these judgments and verification analysis have detailed operation methods.

For example, when judging age, the area of ​​palms is smaller when people are young, and the fingerprint lines appear thinner.

By the thickness and density of the lines, one can tell whether the person is a child or an adult.

After data comparison, the approximate age range can be locked.
