Lu Chuan now has a total of three primary skills.

They are primary on-site survey photography, primary footprint analysis and primary fingerprint identification and analysis skills.

The True Eye is a passive ability, a newbie package rewarded by the system, and there is no possibility of improvement.

Both fingerprinting and bone identification and analysis skills are intermediate.

Therefore, this time the skill upgrade card, Lu Chuan can only be used for on-site photography, footprint analysis and fingerprint identification analysis.

The three skills are of great help to Lu Chuan.

Now survey and take pictures, although it seems that among several skills, it has a relatively small effect on solving the case.

However, when Lu Chuan was in Zhang Wen's murder case, he found the problem through the on-site survey photos.

If Lu Chuan hadn't acquired this skill at that time, the photos he took might not be so complete.

The clues of soot may not be found.

The primary footprint analysis has contributed to Lu Chuan's participation in several cases.

Fingerprint identification and analysis can be said to be one of the most commonly used skills in the daily handling of cases in the field investigation office.

The three primary skills, after any one is upgraded to the intermediate level, there will be a qualitative change.

Having experienced the sweetness of intermediate fingerprint collection and intermediate bone identification and analysis, Lu Chuan is very much looking forward to the next upgrade.

After thinking for a while, Lu Chuan finally chose to upgrade his skills in primary fingerprint identification and analysis.

After all, fingerprint identification is more common than footprints.

Now survey and take pictures, if there is no homicide, it is not much.

"Choose to upgrade your primary fingerprint analysis skills!"

The thought in his heart fell, and the colorful light of the Dao Dao shuttled in Lu Chuan's mind.

The most important step in fingerprint identification analysis is not comparison, but the preprocessing of fingerprints.

Compared with the primary fingerprint identification analysis, the preprocessing methods of fingerprints in the intermediate fingerprint identification and analysis skills are more abundant.

It's also going to be faster.

The analysis of primary fingerprint identification has given Lu Chuan the ability to be basically equivalent to Liu Guodong and others in terms of fingerprint identification, or a little higher.

As for the intermediate fingerprint identification and analysis skills, Lu Chuan estimated that he already had the level of experts from the provincial department.

Of course, there is no practice yet, whether it can be compared or not, Lu Chuan is only guessing by comparing the intermediate skeleton identification and analysis skills.

The on-site work ended soon after Liu Guodong and others came to support.

The criminal suspect Tian Yongjiang and the rescued hostage Liang Qi also went through the transfer procedures in the afternoon and transferred them to the Tianzhou City Criminal Investigation Detachment.

The case was originally theirs, and the injured were also the criminal police of the Tianzhou Criminal Investigation Detachment.

Therefore, according to the usual practice, the follow-up investigation of the case is also a matter for the Tianzhou Criminal Investigation Detachment.

After all the work on the scene was over, Lu Chuan was a little tired and sat in the ten-year Cruiser.

"Lu Chuan, what's going on with Tian Yongjiang?"

When evacuating the scene, Zhang Hui and Lu Chuan made the same car.

Hearing Zhang Hui speak, Lu Chuan reacted: "Brother Hui, I haven't thanked you for saving your life!" ”

What happened to Tian Yongjiang at noon, and being recognized by the other party, really brought a lot of pressure to Lu Chuan.

He is not a front-line criminal policeman, and he has not yet taken the relevant exams for gun permits.

Therefore, Lu Chuan did not have a gun on him.

In fact, even with a gun, it is difficult to be effective at that distance.

The investigators of the Tianzhou City Criminal Investigation Detachment are veterans, although they do not have guns because they are out of the jurisdiction to handle cases

But the strength is not worse than Zhang Hui, but when the other party opens the door unexpectedly and goes directly to the knife, he is still seriously injured.

Fortunately, the rescue was timely, the other party was in a hurry to escape, and there was no mending the knife, and now the person is fine, otherwise the matter will really be big.

In the car, Zhang Hui's face was a little unsightly: "Lu Chuan, when I leave, I will tell you, don't act privately, why don't you listen?" ”

After Zhang Hui escorted Chen Qing away, he happened to meet the police who returned to the Longshan Police Station on the way to assist in patrolling the streets.

He was also afraid that Lu Chuan would have a problem alone, after all, this was the first time he had participated in the investigation.

So, I hurried back.

Which Cheng thinks, what is afraid of what.

As soon as Zhang Hui came back, he saw Tian Yongjiang rushing towards Lu Chuan with a knife.

He almost pulled out his gun and shot it directly.

Seriously, Lu Chuan couldn't help it at that time.

He originally followed what Zhang Hui said, hiding more than a hundred meters away from the warehouse, and kept watch.

Who would have thought that he would meet Tian Yongjiang and borrow fire from him?

Lu Chuan briefly said the process: "He said that I smoke China, it is impossible to come to this place to find women, and he said that I am handsome, and it is impossible to lack women......"

Zhang Hui half-opened his mouth, what is this......

It's a bit wronged.

However, no matter what the process is, if Lu Chuan didn't do it at that time, Tian Yongjiang should not take the initiative to attack.

"Xiao Lu," Zhang Hui's tone softened a little, and the title changed from Lu Chuan to Xiao Lu: "No matter what, you shouldn't have taken the initiative at that time." ”

"I know, you are considering the other party alone, there is no hostage to coerce, and the opportunity to capture is rare."

"However, the premise of all this is to ensure their own safety."

"The colleagues of the Tianzhou Criminal Investigation Detachment were injured because of carelessness."

"Team Qin and Brother Qiang handed you over to me, they just don't want you to have an accident, I can't help you hide this matter, I have to report it."

Five years of work experience has allowed Zhang Hui to see a lot of things.

In fact, only Lu Chuan and Zhang Hui knew the circumstances of Tian Yongjiang's arrest at that time.

can be said here, Zhang Hui doesn't say it, no one will know about Lu Chuan's private attack at all.

However, there are some things that cannot be hidden.

This time I helped Lu Chuan hide it, then Lu Chuan would not have a long memory.

Maybe next time.

At that time, there may not be Zhang Hui in time.

Lu Chuan may pay a big price.

Some mistakes can be corrected if they are not subjectively wanted to be corrected.

Lu Chuan didn't expect that his thoughts at that time would be analyzed so accurately by Zhang Hui.

For a moment, I was a little stunned.

Seeing this, Zhang Hui sighed: "Xiao Lu, I know you don't understand why I did this. ”

"However, there are some things that are too late when they do happen."

Four years ago, just one year after Zhang Hui joined the police, his brother in the same dormitory worked in a grassroots police station.

Because of his own actions, he was seriously injured in the arrest of a robbery suspect.

Later, although his life was saved, his spleen was removed, and he could not go to the front line in the future.

Lu Chuan came back to his senses, where did he not know that Zhang Hui had misunderstood himself: "Brother Hui, you misunderstood, I was thinking just now, how do you know when I arrested Tian Yongjiang, what do you think?" ”

"At that time, I just thought of the situation of Liang Qi's hostage......"

"Brother Hui, don't worry, even if you don't report, I have to report too."

"Invite Brother Hui to dinner in the evening, thank you for saving your life!"

Seeing Lu Chuan's sincere expression, Zhang Hui patted Lu Chuan on the shoulder: "You don't have to eat, you can think like this, don't think that I rob you of your credit." ”

"Brother Hui, what do you think of me, if it weren't for you this time, I might be finished."

"I have to eat at night, call the previous team leader and my master ......"
