1995, Starting as a Criminal Investigation Expert

I was lucky today; the national highway wasn't too congested, and I arrived in Matsuura in just four hours.

It was just past seven o'clock, and it was already dark.

Li Shu drove around looking for a restaurant, asking if they wanted to eat first before going.

"What are you saying? When we come to someone else's turf, how can we expect to pay for our own meals?"

Han Jianjun had no concept of politeness and urged Li Shu to head straight for room 803.

Because of the radio drama, 803 is well-known throughout the country.

"Captain Han, have you met Detective Ningjiang?" Li Shu asked.

Among the 803 members, the most famous is Duan Chengyan, known as the "Detective of Ningjiang" and the "Oriental Sherlock Holmes".

Han Jianjun nodded.

How come I've never seen that before? For example, the Jianfeng Hotel case was personally investigated by Duan Chengyan, the then head of the Criminal Investigation Department.

"No doubt about it, the moment you see this person, you can tell he's extraordinary, especially his eyes. You can't quite put your finger on it, but they're like Erlang Shen's heavenly eyes, able to see right through you."

Han Jianjun is a senior figure, and there aren't many people he truly admires, but Duan Chengyan is definitely one of them.

Now, we might also need to add Li Shu.

As he spoke, a thought struck him, and he suddenly turned to look at Li Shu.

Li Shu was completely unaware of what Han Jianjun had said, but upon hearing it, he felt his blood boil.

Unfortunately, he has already retired, so I guess I won't be able to see him again.

After showing their identification, they drove into the 803 compound.

Before coming, I called Chen Shengkang, the deputy director of the Criminal Science Institute, and we agreed to wait for him to arrive.

Han Jianjun had been here more than once and knew the way well, so he went straight to the small building of the Criminal Science Institute.

On the way, I kept saying that it's a big city after all, and people here have their own office buildings.

Li Shuxin thought to himself, "That's different."

They're at the provincial level, the brigade level. What level is Nanjiang at?

The lights are on, and people are there.

Surprisingly, I even ran into someone I knew.

"Brother Kun, what are you doing here?" Li Shu asked in surprise.

It's Liu Weikun.

When he arrived, he was having tea and chatting with Chen Shengkang and the others.

Chen Shengkang, in his forties, with a side-parted hairstyle and ordinary looks, asked in surprise, "You two know each other?"

Han Jianjun shook hands with Liu Weikun and said, "Last month we bought the AFIS system, and it was Engineer Liu who came over to debug it for us."

Then, he nervously asked Liu Weikun what he was doing here.

"Director Zhou, is your system broken?" Han Jianjun asked Zhou Xuewen, the director of the Criminal Science Institute.

Han Jianjun's first thought was that there was a problem with the system, so Liu Weikun came to provide after-sales service.

If that's the case, wouldn't I have made a wasted trip?

Zhou Xuewen, wearing glasses and true to his name, was refined and gentle. He chuckled and scolded, "Han Jianjun, can't you wish us well for once? Engineer Liu is here to help us upgrade the system."

"You guys really got lucky. This system has even more features after the upgrade. Not only can it directly search the database, but it can also compare data by region. It's really impressive."

Upon hearing this, Han Jianjun almost burst out laughing.

"Director Zhou, do you know why they were able to upgrade?" He couldn't help but feel smug.

Zhou Xuewen was taken aback, thinking to himself, "It can't possibly be related to you, can it?"

Han Jianjun tried to keep them in suspense, but Liu Weikun, who was standing next to him, spoke bluntly, pointing at Li Shu and saying, "Director Zhou, the new features in this upgrade were actually developed by them in Nanjiang."

The two were taken aback.

"Really? You know about computers?" Chen Shengkang asked incredulously.

Han Jianjun, an old guy, probably only knows how to turn on a machine, yet he can help Peking University's research team with technological upgrades?

Han Jianjun glared at him: "I may not understand, but some of us do."

As he spoke, he pulled Li Shu in front of him and said with a proud look, "Let me introduce you. This is Li Shu, a newcomer in our bureau. You all have to thank him for being able to use this district comparison function now."

Li Shu smiled sheepishly and quickly became modest.

The two people in front of me are almost on par with Tang Weidong in terms of status.

"Engineer Liu, is that so?" Zhou Xuewen asked hurriedly.

Liu Weikun nodded: "That's right. They bought our system after a robbery of an armored truck in Nanjiang last month."

He briefly explained the situation.

The Matsuura system was the first client of the Peking University team.

When it comes to software upgrades, we certainly can't forget about them. Liu Weikun happened to come over these past two days to help with the upgrade.

"My God, these are really young people, just like Sun Pingyuan, amazing." Chen Shengkang exclaimed in disbelief.

Zhou Xuewen nodded repeatedly, staring intently at Li Shu.

Regarding this system upgrade, he specifically asked Liu Weikun why it was necessary to conduct a zone comparison.

I only just learned about this completely new approach to fingerprint comparison.

To be honest, as an elderly man in his 803rd year and an expert in trace evidence identification, he was truly amazed.

I only found out now that this method actually came from such a young man as Li Shu.

"The younger generation is truly formidable."

Zhou Xuewen sighed deeply.

Seeing that the gossip had gone too far, Li Shu gently nudged Han Jianjun, reminding him that it was time to get down to business.

"No rush, let's eat first. I've already made a reservation and am just waiting for you to arrive." Chen Shengkang's eyes were fixed on Li Shu.

Such a talented young man is a rare find, so we must have a good chat with him.

I reckon this meal was originally intended to entertain Liu Weikun.

Zhou Xuewen asked two young men from the institute to accompany him, one of whom was Sun Pingyuan, whom Chen Shengkang had just mentioned.

I learned from our conversation that he was a top student from the Department of Biology at Matsuura Normal University, class of '92.

This year, under his leadership, the Matsuura Institute of Criminal Science established a DNA laboratory.

He's only 25 this year, still a promising young man.

When the topic of DNA came up, Han Jianjun couldn't help but ask a few more questions, inquiring about how much it would cost.

He'd been eyeing this thing for a long time.

Upon inquiring about the price, I promptly abandoned the idea.

It was almost nine o'clock in the evening after dinner, and everyone should have gone home.

We can deal with the fingerprint comparison tomorrow.

As a result, when the topic of the case came up at the dinner table, and Li Shu proposed a comparison method for this fingerprint without a scale, Zhou Xuewen and his companion were once again shocked and eager to see it for themselves.

He hurriedly returned to the Criminal Investigation Institute.

Watching Li Shu skillfully operate the computer, constantly specifying scales and making comparisons using numerical lines, the two of them were truly amazed.

"Old Han, this kid is something else," Chen Shengkang said in a low voice, pulling Han Jianjun along.

Just being proficient in using the system and understanding its principles is enough to qualify someone as a talent.

Not to mention that Li Shu also proposed various innovative fingerprint comparison methods.

Many people go through a lifetime without ever coming up with even one.

Li Shu is quite something; he's only been with the company for a little over a month, and he already knows several things.

They also solved several major cases.

I've seen hot-blooded young people, but I've never seen anyone this hot-blooded.

Han Jianjun, his face flushed from the wine, now couldn't hide his pride as he said, "What do you think? You know Liu Zhenping, right? He always praises Li Shu for being so capable."

Zhou Xuewen clicked his tongue in amazement.

Liu Zhenping is a renowned fingerprint identification expert in China.

Liu Weikun huddled up to Li Shu, watching him operate the system. The more he watched, the more excited he became. He said, "Li Shu, your method is quite interesting. I think we could definitely add a function to manually specify the scale later."

Li Shu was taken aback and quickly asked if it was okay.

Currently, we still have to manually adjust and scale the settings. If there were a dedicated function that could automatically adjust the settings according to a fixed ratio, it would be much more convenient.

Unfortunately, despite continuous adjustments, a match was never found.

Li Shu couldn't help but feel anxious.

On the way here, Li Shu thought about it and felt that there was a good chance.

Because Matsuura is a municipality directly under the central government and one of the most economically developed areas in the country, it has a large migrant population, and their fingerprint database is more comprehensive.

Nanjiang had 160,000 copies, while they had a total of 510,000 copies.

Be patient and keep adjusting.

When the settings were adjusted to 26 lines, another set of results appeared.

Li Shu's heart skipped a beat as he stared intently at the fingerprint on the screen that had the highest probability of being the one in question.

"Team Leader Han!"

Li Shu quickly called out.

The group of people who were chatting quickly gathered around and looked at the screen.

Chen Shengkang is considered a pioneer in the field of 803 trace evidence testing, with extensive experience in fingerprint comparison. Looking at the two magnified fingerprints on the screen, he immediately formed an intuitive judgment.

They are similar, and they are from the same person.

Han Jianjun excitedly slapped Li Shu on the back and shouted, "Good lad, solving two cases in one day, you're the real detective!"

Even without a scale, they still managed to make perfect comparisons.

If this isn't a detective, then what is?
