Lu Chuan now has a total of three primary skills.
They are primary spot photography, primary footprint analysis and primary fingerprint identification analysis skills.
The Eye of Truth is a passive ability, a novice gift package rewarded by the system, and there is no possibility of improvement.
The skills of fingerprint collection and skeletal identification and analysis are both intermediate.
Therefore, this time the skill upgrade card can only be used by Lu Chuan for on-site survey photography, footprint analysis and fingerprint identification analysis.
These three skills were of great help to Lu Chuan.
Although it seems that among the skills of spot investigation and taking photos, it has the least effect on solving crimes.
However, when Lu Chuan was involved in Zhang Wen's murder case, he discovered the problem through the photos.
If Lu Chuan had not acquired this skill at that time, the photos he took might not be so complete.
Clues from soot may not be found.
The preliminary footprint analysis has made great contributions to Lu Chuan's participation in several cases.
Fingerprint identification analysis can be said to be one of the most commonly used skills in daily case handling in the investigation office.
After any of the three basic skills is upgraded to the intermediate level, there will be a qualitative change.
Having experienced the benefits of intermediate fingerprint collection and intermediate skeletal identification and analysis, Lu Chuan is very much looking forward to the next upgrade.
After thinking for a moment, Lu Chuan finally decided to upgrade his basic fingerprint identification and analysis skills.
After all, identification of fingerprints is more common than footprints.
If there is no murder case for on-the-spot investigation and photography, it won’t be used that much.
"Choose to upgrade your primary fingerprint identification analysis skills!"
The thoughts in his mind fell, and colorful lights shuttled through Lu Chuan's mind.
The most important step in fingerprint identification analysis is not the comparison, but the preprocessing of the fingerprint.
Compared with primary fingerprint identification analysis, the pre-processing methods for fingerprints in intermediate fingerprint identification analysis skills are more abundant.
It will also be faster.
The primary fingerprint identification analysis made Lu Chuan 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 was already at the level of an expert from the provincial department.
Of course, there is no practice yet. Lu Chuan can only guess whether it can be compared with the intermediate skeleton identification and analysis skills.
The work on site ended quickly 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 were transferred to the Tianzhou City Criminal Investigation Detachment.
The case originally belonged to them, and the injured person was also a criminal police officer from the Tianzhou Criminal Investigation Detachment.
Therefore, according to usual practice, the subsequent investigation of the case is also the matter of the Tianzhou Criminal Investigation Detachment.
After all the work on site was over, Lu Chuan got into the ten-year-old Cruiser a little tiredly.
"Lu Chuan, what's going on with Tian Yongjiang?"
When evacuating the scene, Zhang Hui and Lu Chuan took the same car.
Hearing Zhang Hui speak, Lu Chuan finally reacted: "Brother Hui, I haven't thanked you for saving my life yet!"
The encounter with Tian Yongjiang at noon and being discovered by the other party did put a lot of pressure on Lu Chuan.
He is not a front-line criminal police officer, and he has not yet taken the relevant test for his gun license.
Therefore, Lu Chuan did not have a gun with him.
In fact, even if you carry a gun, it will be difficult to be effective at that distance.
The investigators of the Tianzhou City Criminal Investigation Detachment are veterans. Although they are out of their jurisdiction to handle cases, they do not have guns.
But his strength was no worse than Zhang Hui's, but he was still seriously injured when the opponent unexpectedly opened the door and struck directly with the knife.
Fortunately, the rescue was timely. The opponent was in a hurry to escape and did not do any last-ditch attacks. Now he is fine. Otherwise, things would have really been a big deal.
In the car, Zhang Hui's face looked a little ugly: "Lu Chuan, I told you when I left that you must not act privately. Why didn't you listen?"
After Zhang Hui escorted Chen Qing away, he happened to meet the policemen who were returning to Longshan Police Station to assist in patrolling the streets.
He was also afraid that Lu Chuan would cause problems alone. After all, this was his first time participating in an investigation operation.
So, I hurried back.
Don't even think about it, you are afraid of something happening.
When Zhang Hui just came back, he saw Tian Yongjiang rushing towards Lu Chuan with a knife.
He almost took out his gun and shot directly.
To be honest, Lu Chuan had no choice at the time.
He originally followed Zhang Hui's instructions and hid more than a hundred meters away from the warehouse, watching from the corner of his eye.
Who would have thought that he would meet Tian Yongjiang and try to borrow a fight with him?
Lu Chuan briefly explained the process: "He said that I am a Chinese smoker and there is no way I would come here to find a woman. He said that I am handsome and there is no way I am short of women..."
Zhang Hui half-opened his mouth, what the hell...
It's indeed a bit unfair.
However, no matter what the process was, if Lu Chuan had not taken action at that time, Tian Yongjiang would not have taken the initiative to attack.
"Xiao Lu," Zhang Hui's tone softened a little, and his title changed from Lu Chuan to Xiao Lu: "No matter what, you should not have taken the initiative at that time."
"I know that you are considering the other party alone. There are no hostages, and the opportunity to catch him is rare."
"However, the premise of all this is that one's own safety must be guaranteed."
"Colleagues from the Tianzhou Criminal Investigation Detachment were injured because of their carelessness."
"Captain Qin and Brother Qiang gave you to me because they don't want anything to happen to you. I can't help you hide this matter. I have to report it."
Five years of work experience have allowed Zhang Hui to see a lot of things.
In fact, only Lu Chuan and Zhang Hui knew the situation of Tian Yongjiang's arrest at that time.
It can be said that without Zhang Hui, no one would know about Lu Chuan's private attack.
However, some things cannot be hidden.
If you help Lu Chuan hide it this time, Lu Chuan will not have a long memory.
This may happen next time.
By that time, Zhang Hui may not appear in time.
Lu Chuan may pay a big price.
Some mistakes cannot be corrected if you want to correct them subjectively.
Lu Chuan did not expect that his thoughts at the time would be analyzed so accurately by Zhang Hui.
For a moment, I was a little dazed.
Seeing this, Zhang Hui sighed: "Xiao Lu, I know you don't understand why I did this."
"But, for some things, it's too late when it really happens."
Four years ago, just a year after Zhang Hui joined the police, his brother in the same dormitory worked at the grassroots police station.
Because he acted privately, he was seriously injured while arresting a robbery suspect.
Although his life was saved later, his spleen was removed and he will not be able to go to the front line in the future.
Lu Chuan came back to his senses and realized that Zhang Hui had misunderstood him: "Brother Hui, you misunderstood. I just thought, how did you know it was time for me to arrest Tian Yongjiang? What did you think?"
"At that time, I was thinking of Liang Qi's hostage situation..."
"Brother Hui, don't worry, even if you don't report it, I still have to report it."
"Invite Brother Hui to dinner tonight. Thank you for saving your life!"
Seeing Lu Chuan's sincere expression, Zhang Hui patted Lu Chuan on the shoulder: "There's no need to eat. If you think so, don't think I'm taking your credit."
"Brother Hui, who do you think I am? If it hadn't been for you this time, I might have been doomed."
"We have to eat tonight, call the previous team leader and my master..."
