1995, Starting as a Criminal Investigation Expert

A restaurant near the Municipal Bureau.

When it was time to leave work, Peng Rongfei pulled the two of them aside and offered to treat them to dinner.

He still has some questions about the AFIS system and doesn't understand it, so he wants to ask Li Shu for advice.

"Computers will be everywhere in the future. I'm an old-fashioned person, I can't afford not to learn," Peng Rong said while picking up some food.

He's only 25, hardly an old man.

Peng Rong witnessed the widespread adoption of computers.

If you don't understand, you might really be eliminated.

Li Shu thought so too.

On the system side, there is a dedicated sixth category: electronic data verification, which involves computers.

Is it okay not to study computers?

Li Shu then considered whether or not to get a whole computer.

The problem is that this thing is ridiculously expensive.

One unit costs several thousand.

I only earn three or four hundred yuan a month, and I would have to save up for dozens of months without eating or drinking to afford it.

If I want it right now, the only way is to get some financial support from my family.

Fortunately, they had some savings.

The key thought is that I'm an adult, I have a job, and I can support myself.

As a result, he still has to rely on his parents.

But this is a trendy thing, the trend of the future.

If you know computers, it will be an advantage at work.

My dad always tells me to work hard and be ambitious.

We can't just offer verbal support; we have to actually contribute.

With that thought in mind, Li Shu made up his mind to call his father and ask for money.

Just then, Peng Rong's pager went off.

He glanced at it and hurriedly said, "Li Shu, Captain Han wants to see you. He wants you to come back to the station."

Li Shu dared not delay, quickly picked up two bites of food, and hurriedly went out.

Before leaving, he quietly settled the bill, then got on his bicycle and headed to the bureau.

It was almost eight o'clock when I got back to the station.

I went upstairs to the office, but Han Jianjun wasn't there.

But I've already told the person on duty to let Li Shu go to the 19th floor.

The bureau chief has contacted them.

Upon hearing this, Li Shu immediately became uneasy.

Chief, it's probably not a good thing that you're looking for a trainee police officer who's only been on the job for a few days.

Not daring to delay, they quickly took the elevator upstairs.

I was still dizzy when I got out of the elevator.

I haven't been up to the 19th floor.

Before he could walk two steps, someone called out to him.

A young man in his thirties, with a gentle demeanor, introduced himself and revealed that he was Director Tang's secretary, surnamed Chen.

"Secretary Chen, what does Director Tang want with me?"

Li Shu asked cautiously.

Secretary Chen must have noticed Li Shu's nervousness, so he offered a gentle explanation.

It turns out that Han Jianjun had approached Director Tang, and now Director Tang wanted to hear Li Shu give a report on the AFIS system.

Li Shu calmed down a bit and felt more confident.

However, after following Secretary Chen into a conference room on the top floor and seeing the situation inside, Li Shu was stunned again.

It was a fairly large conference room, the kind where national flags were hung at the back.

Then Han Jianjun and Xu Qiang were both there.

Sitting in the very center was a middle-aged man with a side-parted hairstyle, a square face, and somewhat dark skin.

It should be Tang Weidong, the director of the Nanjiang City Public Security Bureau.

There were five other people sitting to his left and right.

They were of different ages, but judging from their demeanor and shoulder insignia, they were probably all deputy directors or at the level of the bureau's party committee.

As soon as Li Shu entered, everyone looked at him.

To say I wasn't nervous would be an exaggeration.

After all, the person sitting in the middle is a deputy director-general.

"take it easy."

Tang Weidong noticed Li Shu's nervousness and, upon speaking, smiled and said cheerfully, "Old Han said you're self-taught and understand this AFIS system. That's why I took up a little of your time after get off work to have you come over and introduce this thing to us old guys."

Despite the significant difference in their ranks, Tang Weidong didn't put on any airs of a high-ranking official when facing Li Shu, a trainee police officer. He was not only approachable but also spoke with a sense of humor.

A middle-aged man next to him chimed in, saying that was right. Back then, they relied entirely on their legs to solve cases, but now, in just a few years, they've started using computers to compare fingerprints.

Han Jianjun was a little anxious and urged Li Shu to explain the working principle of the AFIS system and his own partition comparison method.

Li Shu composed himself and asked Secretary Chen for another blackboard, where he wrote and introduced the topic as he went.

I've introduced this before, so let's review it again. No problem.

When introducing the partition comparison method, I would like to mention that to use this method to compare incomplete fingerprints, you must have an AFIS system.

But after thinking about it, I decided against it.

This is not something I should say.

Moreover, the fact that Han Jianjun had come to introduce him meant that he had already laid the groundwork, and Tang Weidong had become interested.

Li Shu finished his introduction very quickly.

Tang Weidong nodded slightly, smiling as he praised Li Shu for his excellent and clear explanation, saying he understood everything.

Turn to the deputy directors and ask if there's anything else they don't understand.

After confirming that there was nothing wrong, Chong Lishu waved his hand, telling Lishu to go back first.

He also praised Li Shu a couple of times, mentioning the rapid positioning method that Li Shu had developed before.

"You're so young, this is the time to build your career. Do your best, I have faith in you."

Tang Weidong's final words, "I have high hopes for you," made Li Shu feel as if he had just received a piece of candy, and he couldn't help but feel a little unsettled.

There are so many police officers in the city, it's not easy for the chief to remember you.

Secretary Chen saw Li Shu off at the door and even escorted him to the elevator.

Xiaoxiao pressed the elevator button for Li Shu and they left.

Once outside the building, Li Shu calmed down a bit.

Being praised is a good thing, but more importantly, the AFIS system may have a future.

really.

The next afternoon, Han Jianjun announced to everyone with great excitement.

The Party Committee of the Bureau has basically made a decision to introduce the AFIS system.

They weren't exactly overjoyed, but they were pretty close.

Fingerprint matching is definitely the task that everyone in the entire technical team hates the most.

In Zhao Yong's words, all the elderly people in the team have herniated discs, and most of them developed the problem from lying down for too long while matching fingerprints.

The only drawback is that it's not an imported system.

It's made in China, supposedly to support domestic operating systems.

"Anyway, don't complain. Old Cao said that the domestic system is pretty powerful now."

Han Jianjun also communicated with Cao Junfei, and it is said that the domestic system is not bad.

The main advantage is the convenient after-sales service; any problems can be resolved immediately.

As he spoke, he beckoned to Li Shu: "Li Shu, we have the system, but I feel like you're the only one in the whole team who knows anything about it. You said yesterday that we need to build an archive in the early stages. How do we do that? You need to step up and tell us how to do it."

"We need to get this system up and running as soon as possible, and we also need to get the curved surface photography method you mentioned working, and see how exactly to do it."

After saying that, Han Jianjun himself found it unbelievable.

After all, Li Shu has only been with the team for a few days, and now a whole bunch of things are falling on this newcomer's shoulders.

Everyone turned to look at Li Shu.

Seeing that Li Shu didn't speak, Zhao Yong thought that Li Shu was intimidated, so he said, "Li Shu, don't think too much. The important thing now is to get things done. Anyway, we'll listen to you. After all, you're the only one who understands this stuff."

He's not even proficient with the mouse yet.

Li Shu wasn't intimidated; rather, he was thinking that if they were to create a fingerprint database, the encoding method he had previously mentioned could be prepared in advance.

And this half of a fingerprint.

It will probably take some time before the system is in place, so we can take this opportunity to study it in advance and make preparations.

Once the system is available, the fingerprint database will be established, and comparisons will be performed immediately.

As for the issue of stage fright.

There's a saying that goes something like, "A newborn calf is not afraid of a tiger." Li Shucai wouldn't miss an opportunity to prove himself.

While everyone was busy encoding the fingerprint card and studying the half fingerprint, a major incident occurred on September 5th.

That morning, not long after Li Shu started work, around nine o'clock, he received a phone call.

There's a case.

It's a major case. In Xinbei District, north of Nanjiang, and below Yanqiao Town, at the Nanjiang Rural Credit Cooperative, Yanqiao Branch, criminals robbed an armored truck at gunpoint.

Several shots were fired, killing and wounding the guards and several bank employees.

Upon hearing this, everyone present changed their expressions drastically.

Li Shu's heart pounded wildly.

Robbing an armored truck is a really big case.
