We asked you to solve cases, and here you are sharing your criminal experiences?

In Jiangcheng after the start of autumn, it rained for several days in a row.

The temperature dropped sharply.

In this awful weather, even street thugs don't want to go out for a stroll.

But there are always a few who value money more than their lives.

It's 11 p.m.

The atmosphere in the task force's office was somewhat heavy.

A security camera video of a convenience store is playing on a loop on the large screen.

This is a 24-hour convenience store in the northern part of Jiangcheng.

The video footage is somewhat blurry.

The time displayed in the upper right corner is 2:15 AM.

A man wearing a black raincoat and a fully enclosed motorcycle helmet walked into the store.

The convenience store clerk is dozing off.

The helmeted man walked straight to the cashier and pulled out a gleaming watermelon knife from under his raincoat.

"Don't move! Hand over all the money!"

Although you can't hear his voice, you can tell from his actions that he's threatening you.

The clerk was terrified and quickly opened the cash register drawer.

The man in the helmet acted roughly.

He grabbed the several hundred yuan in loose change and stuffed it into his pocket.

Then he turned and ran.

The whole process took less than a minute.

Clean and efficient, without any hesitation or fuss.

After watching the video, Zhao Ming scratched his head and looked at Gu Tingchen with some confusion.

"Captain Gu, isn't this just a typical motorcycle gang robbery?"

Zhao Ming pointed at the screen.

"The case value is only a little over six hundred yuan, which doesn't even meet the criteria for a serious crime."

"The North District branch can handle this perfectly well, why did our task force take on this case?"

The other officers nodded in agreement.

They are the elite team investigating murder and serial crimes.

Are you suggesting they catch petty thieves who rob convenience stores now?

Isn't that a bit of a waste of talent?

Gu Tingchen sat behind his desk, twirling a pen in his hand.

His face was hidden in the light, making him appear very cold and stern.

"If it's just one case, then it does fall under the jurisdiction of the branch office."

Gu Tingchen threw a summary report on the table.

"But this is the seventh case in three days."

"Seven convenience stores, located in three different areas of Jiangcheng."

"The suspect's height, build, and modus operandi are completely identical."

"Most importantly," Gu Tingchen tapped his finger twice on the table.

"Their route of committing the crime formed a perfect regular hexagon."

"This is definitely not a blind, itinerant crime, but a highly purposeful plan."

Zhao Ming flipped through the report and still found it unbelievable.

"Planning such a meticulous route for a few hundred dollars? This thief must be out of his mind."

Song Qianxia sat at her workstation against the wall.

She was holding nail clippers and snip-snip-snip-cutting her nails.

These past few days have been fortunate that Lin Wan was assigned to maintain order.

No one in the task force was watching her.

She embodied the spirit of salted fish to its fullest extent.

Hearing Zhao Ming's words, she lazily looked up at the big screen.

The video then looped back to the scene where the helmeted man was grabbing money.

Song Qianxia stopped moving.

The nail clippers stopped in mid-air.

As a former top figure in the underworld, her sensitivity to detail is practically obsessive.

"Um..." Song Qianxia suddenly spoke up, breaking the office discussion.

Everyone turned to look at her.

She pointed to the big screen.

"Xiao Wang, please rewind the video and go back to the thirty-seventh second."

Xiao Wang hesitated for a moment, but still did as instructed.

The image freezes.

It was at the very moment the helmeted man pointed a knife at the clerk while grabbing money from the cash register with his other hand.

Song Qianxia put down her nail clippers and slowly walked over.

"Zoom in again."

When the image is zoomed in, the picture quality becomes very pixelated.

But the helmeted man's movements are still clearly visible.

Song Qianxia stretched out her finger and tapped the bottom left corner of the screen.

"Look at his left hand."

Everyone looked in the direction she was pointing.

The helmeted man held a knife in his right hand, but his left hand did not reach for the money in the drawer.

His left hand, in an awkward position, reached under the cash register.

That's where the main unit and various cables are located.

Due to the limited angle of view, the surveillance camera could only capture his arm hovering below for about three seconds.

Then he took it out to get the money.

Zhao Ming leaned closer and looked at it for a long time.

"What does this prove? Maybe it was an accidental touch down there."

"It wasn't by chance." Song Qianxia shook her head.

The nonchalance on her face disappeared, replaced by a focused expression.

"Judging from the tension in his arm muscles, this is a forceful thrusting motion."

Song Qianxia turned to look at Gu Tingchen.

"Captain Gu, what's down there?"

Gu Tingchen's eyes sharpened instantly.

He didn't answer, but instead picked up the walkie-talkie.

"Scene investigation team! Head to the seventh crime scene immediately."

"Disassemble the bottom of the cash register, especially the area near the data motherboard, and check it carefully!"

Ten minutes later.

The on-site investigation team sent back a message.

The photos that were sent back showed an old-fashioned data interface hidden under the cashier.

It had a tiny device, about the size of a USB flash drive, plugged in.

"Captain Gu, we've found a data copyer!"

The officers on the investigation team were trembling in their voices over the communication channel.

"The tech team just confirmed that this thing is frantically copying the convenience store's payment records and transaction information for the past two weeks!"

The entire task force office erupted in chaos.

Zhao Ming gasped.

"My God! This isn't a robbery at all!"

The thief's real purpose wasn't the few hundred dollars in cash.

It's the massive payment data flow from convenience stores!

The cash was just a cover for them.

Gu Tingchen placed his hands on the table, his eyes as cold as blades.

"An ordinary robbery has escalated."

"This is a large-scale, organized, and premeditated financial data theft."

He turned to look at Song Qianxia.

The little girl had retreated to the corner again at some point and continued snip-snip-snip-snip as she trimmed her nails.

But Gu Tingchen knew.

If she hadn't noticed that tiny insertion and removal motion at a glance...

Police are still investigating this as a typical drive-by robbery.

Just how many surprises does Song Qianxia still hold?

At this moment, Song Qianxia felt anything but relaxed.

Collect merchants' underlying payment transaction data.

This technique is all too familiar.

This is the first step in building an underground money laundering pool!

This reminds me of the blind bird marker that appeared on the cruise ship a few days ago.

Song Qianxia was certain.

The Night Owls, this pack of mad dogs, are laying a massive black net in Jiangcheng.

And she just happened to step into the center of this net.

Ruined.

I can't live like this anymore!
