As Lu Chuan matched the third murder case, the hero board was updated simultaneously.

The numerous experts still battling at their computers were surprised when the hero board popup appeared, and they clicked it open.

At this hour... another case has been matched.

The achievements of today are unprecedented in the history of fingerprint battles.

Earlier, Tian Rong individually matched five cases, scoring twenty-four points.

Following that, other experts also achieved breakthroughs, and now, ten people have matched cases.

And now, Lu Chuan has even matched three murder cases in a single day!

Three murder cases!

"Damn!"

Zhao Zhigao swore.

"The Meishan Mine Case?"

The expert sent by the Meishan Criminal Investigation Team to participate in the fingerprint battle was Sun Yifan.

When the Meishan Mine Case happened, Sun Yifan had just turned thirty; back then, he was not yet an expert.

However, at the time of the incident, Sun Yifan was already a key figure in the Meishan Criminal Investigation Team and had participated in the case back then.

In fact, the fingerprints on the murder weapon from those years were collected by Sun Yifan.

Therefore, he knows this case better than anyone else.

The death of the Meishan miner wasn't just a simple murder case.

Ten years ago, it was a critical moment for the survival of the Meishan Coal Mine, which was undergoing restructuring at the time.

The final coal mine ownership was dependent on a tender back then.

And it wasn't just one miner who died; other cases have been solved.

Because the other cases have been solved, only one person who fits the investment criteria and hasn't been caught remains.

Now, that person is the owner of the Meishan Coal Mine.

This ten-year-old cold case finally has a lead.

"Teacher Lu!"

Sun Yifan rushed over from his seat, knocking over two chairs along the way.

"The Meishan miner's case... did you match it?"

Zhao Zhigao, recognizing Sun Yifan, introduced him to Lu Chuan: "This is Director Sun from the Crime Scene Investigation Office of the Meishan Criminal Investigation Team."

"Hello, Director Sun."

Lu Chuan greeted him, "I got lucky; it seems like I matched it."

"Who is it?"

Sun Yifan was very excited and tense; he hadn't had a chance to look at the details on the hero board after seeing Lu Chuan matched the miner's case and rushed over straight away.

"It seems to be someone named Chen Hu."

Lu Chuan had only glanced at the results; his main focus wasn't there.

Be it Chen Hu or Zhang Hu, as long as one person matches, Lu Chuan's work is done.

Arrests, interrogations, and case studies are the local police's responsibility.

"Chen Hu?! Is it him?!"

Sun Yifan clearly knew who Chen Hu was. After the case broke out back then, everyone related to the victim was included in the investigation scope.

Everyone who entered the mine around the time of the murder was also under investigation.

Chen Hu was the safety supervisor at the mine back then and is now the safety director of the Meishan Coal Mine.

The current Meishan Coal Mine is under Meishan Mining Investment Group, a listed company. Chen Hu has risen from being a small-time safety officer to a senior executive at the mine.

With the three murder cases, Lu Chuan's battle score also rose to thirty points, reclaiming the top spot on the hero board.

Still in the meeting room, aside from the experts focused on analyzing fingerprints at the crucial moment, everyone else gathered around.

Everyone discussed the fingerprint match Lu Chuan just completed.

Many people have studied the Meishan miner case before, so they discussed it with enthusiasm.

Meanwhile, Li Donglin, who had just returned home from work, received a call from Sun Bing.

"What did you say?!"

Li Donglin's tone rose by eight tones.

"Director Li, Teacher Lu has matched another murder case!"

Matched another case?

Li Donglin felt a tingling sensation on his scalp.

"Which case?"

"The Meishan miner's case, Teacher Lu matched the Meishan miner's case!"

Li Donglin put on the coat he had just taken off, ready to return to the office.

"Working overtime again?"

Li Donglin's wife, who had reheated the dinner she'd prepared long ago, spoke with a tone that was somewhat complaining but more so resigned.

Li Donglin sighed, looked at his wife apologetically, and softened his tone, "The fingerprint battle experts are working overtime, and Lu Chuan, whom I told you about, matched another murder case."

Although Li Donglin's wife wasn't a police officer, she knew something about these matters from exposure.

"Is that the detective who graduated less than a year ago?"

"Yes, he matched a murder case from ten years ago, and I need to arrange it overnight."

Matching in a murder case cannot be delayed for even a moment, and Li Donglin had to deploy immediately.

The Meishan Criminal Investigation Team will be busy tonight as well.

Provincial Bureau.

Li Donglin had just given orders to the Meishan Criminal Investigation Team.

Chen Hu's fingerprint match was successful, and the old case was solved; surely, more than just Chen Hu was involved.

Although Chen Hu was under investigation back then, due to no direct connection or personal grudges with the deceased miner.

Therefore, he was not considered a key suspect in the investigation.

So, why did Chen Hu kill that miner?

The arrest operation was organized promptly.

In the meeting room, Li Donglin met Lu Chuan again.

Li Donglin's expression was excited; when he came to see Lu Chuan earlier, it was half because of their personal relationship and half because Lu Chuan indeed had the capability.

Even though the fingerprint battle organized by the Haizhou City Public Security Bureau wasn't as tough as the provincial level, the murder cases in it were real.

Even those cases were part of the provincial fingerprint battle database.

Yet, Lu Chuan still matched most of them.

The second time meeting Lu Chuan was because Lu Chuan matched a murder case, the first murder case.

The third meeting was also due to a murder case Lu Chuan matched, the second murder case.

This early morning was the fourth time Li Donglin had seen Lu Chuan.

Director Li Donglin felt that today he seemed to be constantly busy around Lu Chuan.

From morning till night.

"Lu, it's already midnight. Why don't you take the lead, and let's all rest first? There are so many cases; we can't solve them all in a day."

Lu Chuan nodded, accepting Li Donglin's suggestion.

Today was indeed quite tiring, especially in the afternoon, spending several hours with little results.

After Lu Chuan left, most people packed up and left, but three experts didn't return to the guest house and instead stayed in the meeting room.

They were so used to working shifts in their units that they couldn't sleep when they went back.

They were dependent on camp beds for sleep.

The next morning.

"Good morning, Teacher Lu!"

"Teacher Lu, may I observe when you're analyzing fingerprints later to learn a trick or two?"

It was Sun Yifan from the Meishan Criminal Investigation Team who spoke up.

The fingerprint battle was, on one hand, about solving unsolved cases and, on the other, providing a chance for fingerprint identification experts within the province to exchange experiences.

In previous years, the experts who participated in the fingerprint battle were all acquaintances, and their special skills had more or less already been shared.

Lu Chuan, being a new force, had tricks that seemed very practical, and everyone wanted to learn.

Yesterday being the first day, many people weren't familiar enough to feel comfortable speaking up.

Now that Sun Yifan had spoken up, others turned their heads to look at Lu Chuan.

"No problem, let's exchange ideas with each other."

"Haha, thank you, Teacher Lu. My skills are average, so today I won't do my analysis but instead focus on learning from you."

Soon after, a group lined up behind Lu Chuan.

Out of over ten experts, eight stood behind Lu Chuan.

Others wanted to come too, including Tian Rong, but they were late and didn't find a spot.

They could only wait for the afternoon.

Lu Chuan didn't mind, opened his computer, searched the murder cases in the fingerprint battle database, and began selecting his next target.
