1995, Starting as a Criminal Investigation Expert

Everyone was in shock.

A middle-aged man stepped forward, helped Zhao Yong up, and said, "I still don't understand, let me try."

He hurriedly sat down, picked up the homemade locator, examined it for a moment, and then quickly bent down to begin comparing it.

Zhao Yong stood beside him, guiding him and telling him what to do.

Several people crowded around and listened attentively.

Some people reacted quickly and already understood the underlying principles.

And I gradually came to understand why this method can greatly improve efficiency.

"Li Shu, right?"

A young man with thick lips, who looked to be only twenty-five or twenty-six years old, stepped forward, shook hands with Li Shu, and introduced himself: "My name is Peng Rong. By the way, I went to the same school as you. I graduated in 91."

As a provincial police academy, graduates will most likely return to their hometowns after graduation.

So it's not surprising to run into senior students in the team, and Peng Rong wasn't the only one.

"Hello, senior brother."

Li Shu realized what was happening and hurriedly called out to his brother.

Peng Rong, his face filled with undisguised shock, asked, "This...this is a new method Old Zhang taught us?"

Zhao Yong just said that this was Li Shu's idea.

But Peng Rong subconsciously thought that this was what the school taught.

He has been out of school for four years, so it's quite possible that the school has developed or he has come into contact with a new method developed by someone across the country.

If that's the case, then it's normal for Li Shu to have learned it right after graduating.

Li Shu quickly shook his head: "No, I figured it out myself."

If it's something taught in school, people can verify it, and then it won't be able to be explained later.

It would be better to just say that you figured it out yourself.

It's just one method anyway, and even if you say it's something you dreamed of, no one will say anything.

Peng Rong stared at Li Shu for a full five seconds, his eyes wide, before patting Li Shu on the shoulder and saying, "Brother, awesome!"

Meanwhile, the middle-aged colleague who had personally conducted the experiment had already grasped the underlying principles.

"Old Zhao, this method is amazing!"

He looked incredulous.

Everyone present nodded in agreement.

If you've seen it all with your own eyes and someone has explained it to you, and you still don't understand, then that's not appropriate.

Only after truly understanding the underlying principles can one realize how convenient this method is.

Fingerprints that don't match at a glance, no matter how fast they are, how much faster can they really be?

The main type is fingerprints that match certain features but are not quite the same.

This kind of talent takes a lot of time.

Li Shu's method perfectly improves the efficiency of fingerprint comparison.

"I think this method is flawless. The feature points can match, but the positional relationship is absolutely correct."

"Indeed, the positional relationship of one or two feature points may overlap, but with five of them, the probability of them completely overlapping is extremely small."

"It's not small. Imagine, in a two-dimensional space, the orientation and distance of five positions completely overlap. I feel that the probability of this is basically equivalent to a match."

The crowd chattered amongst themselves, and as they talked, they all turned to look at Li Shu.

A look of horror crossed his eyes.

"Li Shu, right? You're pretty good, kid. How did you come up with that?"

"This young man has a sharp mind."

Everyone was surprised.

In situations like this, it's time to be humble.

Li Shu said that he figured it out slowly on his own, but he didn't have many opportunities to practice while he was in school. He only started trying it out after he started working.

It turned out to be really useful.

"As for whether it will work or not, to be honest, I'm not sure either. I'll have to ask all the seniors for help to improve it together."

Li Shu adopted a very humble attitude.

My dad always says that you shouldn't be too flamboyant, or people will hate you. Being humble and low-key won't hurt you.

"You little rascal, you're being modest now."

Zhao Yong punched Li Shu in the chest and said cheerfully, "You deserve credit for this. This method is really useful, and we should thank you for saving us a lot of effort."

The elderly people present all nodded in agreement.

Technical police officers, unlike those in operational roles, aren't constantly busy when cases come in.

Once the work is done, it's like sitting in an office; you can leave on time.

There are fewer people around now, and then this big case comes along.

When it comes to fingerprint matching, I'm away from home for days and nights. Not only am I exhausted, but my family also has their complaints.

The children are no longer being picked up, and the elderly are no longer being cared for?

Li Shu came up with a good method, which effectively reduced the burden on everyone.

As for Zhao Yong's suggestion to record Li Shu's merits.

What, are you jealous of a young person and trying to steal credit from a newcomer?

Not to mention genuine innovation; you can't steal it even if you want to.

"Alright."

Zhao Yong told everyone to stop talking and said, "Hurry up, Li Shu, you get the locator. Let's get right to it. The first team is getting impatient."

If we have a new method, we should use it, and we should use it as soon as possible.

Solving cases waits for no one.

Li Shu nodded and quickly called Tan Guoxiong to help him set up the locator.

Everyone rushed forward to help.

They even suggested optimization methods, such as making a wooden frame, fixing it in place, and making it a hinged design so that the plastic film in the middle can be directly replaced later.

Another suggestion was to first draw the core area on the thin film, which would facilitate positioning.

Many hands make light work.

Even with a method, you still need to explore, optimize, and adapt it to existing conditions.

Seeing that Tan Guoxiong was somewhat silent, Li Shu secretly nudged him with his elbow and whispered, "You don't have any ulterior motives, do you?"

Tan Guoxiong was taken aback and asked blankly what he was thinking.

"It's nothing," Li Shu quickly shook his head.

I truly considered Tan Guoxiong a brother and a friend.

Now that everyone is a newcomer to the job, Li Shu is worried that Tan Guoxiong might feel awkward about it.

It's human nature, and it's understandable.

Of course, based on my understanding of Tan Guoxiong, it's unlikely.

If he makes a contribution, he will only bless himself.

Otherwise, the two wouldn't have become such good brothers.

That proved to be true.

Tan Guoxiong said "Oh," hesitated for a moment, and asked, "Li Shu, when did you come up with this method? How come I didn't know?"

I often spent time studying in the library at school, but I never saw Li Shu do that.

Li Shu pointed to his head and said, "You're thinking about it. You should think about it more often when you have nothing to do. Didn't Old Man Zhou say that you should think more?"

Old Zhou is a professor of physics and chemistry testing at the school.

Because it involves chemistry, the course is very difficult.

He always told everyone that rote learning is only the foundation; to learn well, one must also think deeply.

Tan Guoxiong nodded thoughtfully and said nothing more.

Meanwhile, Zhao Yong, in his excitement, thought he should inform Han Jianjun.

This is good news, and leaders like Han Jianjun should know about it.

Han Jianjun went out in the afternoon to attend a meeting at the Tingyang City Public Security Bureau to provide guidance.

Actually, it's not too late to talk about it after the other person comes back.

But after thinking about it, he picked up the phone and paged Han Jianjun, asking him to call him back when he had time, saying there was good news.

It wasn't until the locators were gradually made and everyone started working that Han Jianjun called.

"Zhao Yong, what good news?" Han Jianjun asked wearily.

He hadn't gotten the talent he wanted, the introduction of the AFIS system had suffered a major setback, and with all sorts of other things piling up, he was really hoping for some good news.

Without hesitation, Zhao Yong quickly explained the new fingerprint comparison method that Li Shu had devised.

At the end, Zhao Yong glanced at Li Shu, who was busy in the distance, and said, "This kid is amazing. He has ideas and is definitely a good prospect. I personally feel that his method can at least increase our comparison efficiency by two to three times."

He didn't think this was bragging.

But Han Jianjun was stunned when he heard this on the other end of the phone.

"Zhao Yong, what are you bragging about? Two to three times? You really dare to say that."

Li Shu, a novice and a college student, figured out a way to increase the comparison efficiency by two to three times.

Two to three times that, what does that even mean!

Zhao Yong said, "Old Han, whether he's bragging or not, you'll see for yourself. This kid is really amazing."

In any case, he was quite shocked by Li Shu.
