It's said that even a tiger won't eat its cubs, but the heart of a woman can be the most poisonous.

To kill one's own flesh and blood after raising them for eighteen years—what else can't such a person do?

The interrogation of Sun Jicheng has made a breakthrough, and Wang Huihui probably can't hold on much longer either.

When Chen Ying saw Sun Jicheng's confession, she felt an inexplicable force gripping her heart.

She finally understood that what Wang Huihui did back then wasn't a false testimony at all.

No wonder Wang Huihui didn't have any emotional reaction when faced with inquiries and the irrefutable evidence of Sun Jicheng's murder; she wouldn't say a word.

As it turned out, she was also a participant in the murder case.

Or rather, it wouldn't be excessive to say she was the instigator.

Chen Ying has been a police officer for many years, and she has interrogated many female crime suspects.

Over the years, she has seen too much of the dark side of human nature.

Prostitution, abandoning husband and child, performing live shows—she's seen all kinds of female crime suspects.

But a mother who killed her own flesh and blood—this was the first time she had encountered such a case.

In previous years, there were cases of abandoning babies, but none involved murder.

Moreover, an eighteen-year-old son is different from a newborn child.

Years ago, she read a news story.

A child was run over and killed by a vehicle at school, and the child's mother was so grief-stricken she committed suicide by jumping from her home a few days later.

Not to mention humans, even animals—she saw on a short video platform that in monkey groups, even if a baby monkey dies by accident, the mother monkey still clings to the dried corpse and won't let go.

If animals are like this, then what about humans?

Wang Huihui!

She deserves death!

The net of heaven is vast and wide, with none able to escape.

Anyone who commits a crime will be punished by the law.

They say that heaven's justice has cycles—who can escape the reckoning?

Even after thirteen years, those who owe lives cannot escape.

The Provincial Department.

Fingerprint Warfare Meeting Room.

Li Donglin excitedly patted Lu Chuan's shoulder: "Good, good, good!"

Three consecutive "goods" showed Li Donglin's current mood.

In one morning, two cold case homicides were matched consecutively.

The second one was a serial case of taxi drivers being murdered in Tianzhou City.

This series of cases had a huge impact and spanned a long time; it existed even before Li Donglin started working at the provincial department.

"Sun Bing, arrange for the logistics support office to provide two attendants for the experts, to ensure all their needs are met; look, the tea has gone cold, quickly order someone to make hot tea."

"And bring over a few electric heaters—this is the top floor, and the weather is warming up, so the heating is about to stop, but the indoor temperature is not high; what if the experts catch a cold?"

Zhao Zhigao, Wang Huiyou, Tian Rong, and others either shook their heads or pursed their lips.

This is what treatment looks like.

In the fingerprint warfare organized by the provincial department, as long as you can match a case, especially a murder case, you are treated like royalty.

Most of those present are old-timers in the system.

Though technically skilled and not good at interpersonal relationships, that's just their personality.

They focus on refining their skills, which is how they reached the level of being experts at the provincial department.

Not being good at socializing doesn't mean they don't understand what interpersonal relationships are.

Whether it's the provincial department or lower offices, or even sub-bureaus and police stations, promotion may not have much to do with ability, but as long as you can solve cases—especially those others can't—you can be the most unyielding person, and the director won't bother you.

They might even say, "Look at them—such character."

But without the ability to solve cases, being unyielding is not having character; it's having an issue.

Fingerprint warfare organized by the provincial department doesn't result in cold cases being matched every year.

This time, just one morning in, two murder cases were matched.

One was a thirteen-year-old case, and the other a serial taxi driver murder case, both solved single-handedly by Lu Chuan.

Of course, Li Donglin would provide treatment.

There's still four and a half days to go.

Even if Lu Chuan doesn't maintain the current match speed, with one match per day or even one every two days, he could still match three or four more murder cases.

Adding the two already solved, that would be five or six cases in total.

Five or six homicide cases—the level of even a departmental fingerprint warfare competition.

The briefing ended quickly, and Li Donglin needed to promptly arrange for Tianzhou City Public Security Bureau to apprehend the suspects.

This cannot be delayed.

In no time, the meeting room turned quiet again.

"Teacher Lu, want to take a smoke break?"

Zhao Zhigao pulled out a cigarette and gestured.

Lu Chuan nodded, noting the time; it was almost eleven, and it would soon be time for lunch.

Solving two murder cases in one morning—quite efficient.

"Let's go, Brother Zhao, have one on me."

With that, he took out a pack of Chunghwa to Zhao Zhigao's surprise.

"Does the Haizhou Criminal Investigation Unit pay... that well?"

Zhao Zhigao knew Liu Guodong and had discussed this topic before.

Everyone's pay isn't that different.

In fact, Tianzhou City is more economically developed and offers higher bonuses.

"Not at all, from home."

Lu Chuan smiled and handed a cigarette to Wang Huiyou, who had followed them out.

Coping with crime scene investigations and trace inspections requires high concentration; smoking is a familiar means for boosting alertness.

"Teacher Lu, thank you for that case of ours."

Just moments ago, a colleague of Wang Huiyou had briefed him on the case investigation.

"Brother Wang, you're too kind; it was just luck that I stumbled upon it."

"And please, just call me Lu Chuan, or Lu; being called 'Teacher' feels a bit awkward."

"What's awkward about it? Among us tech specialists, outside of leadership, whoever has the skill is the 'teacher.'

Zhao Zhigao followed up: "You matched two murder cases; in past warfare competitions, many don't even get one."

Wang Huiyou nodded in agreement: "Right, especially with murder cases—weren't they cases where all efforts were put in at the time?"

"Yet they still became cold cases, proving their difficulty."

As the group chatted, others joined in.

The provincial department had a dedicated smoking room indoors, on the top floor, so it didn't affect others.

Chatting also served as a break, a way to relax.

"Old Wang, how's your case coming along?"

An acquaintance inquired about the Qianzhou case.

"It's solved; the suspect was caught and confessed, but the person Lu matched was just one of the perpetrators—there was also an accomplice in the child's murder."

"Oh? Who? Were they caught too?"

It's rare for two people to commit a crime together and not be discovered for so many years.

"They were caught—it was the child's mother."

"His mom?"

Wang Huiyou nodded, took a deep drag on his cigarette: "It's said, when the stepfather was killing the child, the child resisted fiercely, nearly escaping."

"In the end, the child's mother stepped in to help hold the child down, and the child stopped struggling instantly."

Wang Huiyou's words hit everyone like a sledgehammer to the heart.

Lu Chuan was also stunned, taking a long moment to regain his composure.

Sigh...

Someone sighed, and gradually, everyone returned to the meeting room.
