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

Back at her workstation, Song Qianxia immediately plugged the USB key into her computer.

All around, there was the sound of Lao Zheng and his economic crime investigation officers painstakingly searching through piles of paper ledgers.

Song Qianxia put on her headphones and directly accessed the city bureau's intranet system.

With advanced access, all the transaction records of the Jiangcheng Charity Foundation's electronic accounts were instantly displayed on her screen.

"Trying to drown us in paper ledgers? No way!"

Song Qianxia moved her fingers and typed loudly on the keyboard.

She has her own unique logic when it comes to auditing accounts.

When the police audit accounts, they usually go through the reports, invoices, and contracts one by one to see where there are loopholes.

But Song Qianxia didn't do that.

In the underground money laundering world, the accounts are made to look as clean as water. If you follow their logic and investigate, you'll never find anything wrong, no matter how long you look.

When Song Qianxia checked the accounts, she only looked at two things: the accumulation of funds and the disappearance of funds out of thin air.

She pulled out all the sub-projects under the foundation. Her focus immediately fell on a star project executed by the Xinghai Charity Foundation.

"Warm Sunshine Scholarship Program"

This is a project that specifically funds orphans and impoverished students in remote mountainous areas. It has a great reputation and raises tens of millions of yuan in social donations every year.

To ordinary people, this kind of project is the cleanest, the most sacred, and the least likely to have problems.

But Song Qianxia immediately saw through the trick.

She typed rapidly on the keyboard, writing a simple web scraping script.

All the major expenditures of this project over the past three years have been presented.

Ten minutes later, three sets of data appeared on the screen.

Song Qianxia ripped off her headphones, turned around, and called out to the other end of the office, "Old Zheng! Captain Gu! Come here for a second!"

Old Zheng was feeling dizzy from being overwhelmed by a thick book of invoices when he heard the shout. He quickly dropped his pen and ran over.

Gu Tingchen also came out of the office.

"What did you find out?"

Song Qianxia pointed to the three sets of data highlighted in red on the screen and opened the scanned copy of the receipt certificate.

"The Xinghai Foundation's Warm Sunshine Education Assistance Project seems to be working perfectly. Every donation comes with a receipt from a school in a remote area."

"But look at these three large grants. They were from March and September of last year, and January of this year. The amounts are all around three million."

Old Zheng stared at the screen: "What's wrong with the time?"

"This is a big problem."

Song Qianxia brought up another page, which was the public trading calendar of the Cyrillic duty-free port.

"These three sums of money were transferred from the Xinghai Foundation's account to an overseas educational equipment procurement company called Oasis."

Song Qianxia compared the dates on both sides.

"Look closely. The arrival times of these three payments are exactly the same, on the last settlement date of each quarter at the Cyrillic duty-free port!"

Old Zheng's eyes widened, and he gasped.

As a veteran economic crime investigator, he knew all too well what this meant.

"The liquidation day is when the flow of funds in the duty-free port is at its largest and supervision is at its weakest. Countless amounts of black money and white money are mixed together on this day, making it impossible to trace their source!"

Song Qianxia snapped her fingers.

"That's right! These so-called educational donations never turned into books and desks. They were disguised as charity and jumped into the money laundering pools of the duty-free port on time."

"This Xinghai Charity Foundation is essentially a large-scale financial transit point for Night Owl in Jiangcheng!"

Gu Tingchen's face darkened completely.

Using people's kindness to launder money is utterly outrageous!

"Old Zheng!"

Gu Tingchen made a decisive decision: "Take men to the Xinghai Foundation's office building immediately. Detain their cashier and financial manager, and retrieve all original documents!"

"Understood!" Old Zheng stopped complaining about being tired and called to his men to rush out.

Song Qianxia sat in front of the computer, staring at the cold data on the screen with a sharp gaze.

A few hours later.

Jiangcheng University, Department of Sociology Teaching and Research Building.

Sunlight streamed through the huge floor-to-ceiling windows, illuminating the spacious professor's office. Floor-to-ceiling bookshelves lined the walls, filled with various weighty academic works. Several potted plants grew lush and green near the window.

The whole room exuded a strong scholarly atmosphere and a sense of peace.

Cheng Yan sat behind a large mahogany desk. He wore a light gray cashmere sweater and gold-rimmed glasses. Holding a fountain pen, he was carefully grading a student's graduation thesis.

The purple clay teapot on the table was emitting wisps of steam.

Suddenly, the encrypted phone on the table vibrated.

Cheng Yan put down his pen, picked up the purple clay teapot and poured himself a small cup of tea, then slowly answered the phone.

On the other end of the phone came a slightly impatient female voice; it was Yinque, who was in charge of external coordination.

"Night Watchman, something's happened." Silver Sparrow's voice was very low.

"The police didn't bother with the scrap paper and ledgers we deliberately left behind! The Economic Crime Investigation Team stormed into the Xinghai Foundation's premises!"

"They had the approval documents in hand and went straight to the original accounts of the Nuanyang Education Assistance Program!"

Cheng Yan paused slightly in the hand holding the teacup.

He looked up and gazed out the window at the young students running on the Jiangcheng University playground.

The sunlight reflected a cold light off his gold-rimmed glasses.

"The Jiangcheng police acted faster than I expected."

Cheng Yan sighed softly, his tone as gentle as if he were praising his student.

"What do we do now?" Yinque panicked. "That cashier, Meng Xiaoqing, has real money transfer slips! If the police get their hands on them, they can trace everything..."

"What's the panic?"

Cheng Yan interrupted her, picked up his teacup, and took a sip.

The tea is very fragrant and has a lingering sweetness.

What he hates most are subordinates who panic at the slightest setback.

Compared to the Thousand Faces of yesteryear, these people today are sorely lacking in artistic sense.

"Since the police want to investigate, let them investigate."

Cheng Yan put down his teacup, picked up a rag from the table, and slowly wiped away the tea that had accidentally spilled onto the table.

"Notify relevant personnel to initiate the self-cleaning procedure for accounts."

Yin Que was silent for two seconds on the other end of the phone, her voice trembling slightly.

"……clear."

After hanging up the phone, Cheng Yan threw the rag into the trash can next to him.

I picked up my pen again and circled a logical error in the student's paper in red. I then wrote a few constructive comments.

Self-purification is never about destroying any documents.

Because paper documents cannot be completely destroyed.

Only by erasing the people who created these documents, and letting all clues die in the mouths of the dead, can we achieve the most thorough cleanup.

Cheng Yan pushed up his glasses, looked at the pages full of text, and a smile appeared on his lips.

Thousand Faces, let me see how you're going to break this situation.
