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

The banknotes floated lightly onto the appraisal table.

Song Qianxia's voice sounded particularly jarring in the quiet conference room.

She was completely absorbed in her field of expertise and didn't notice the menacing stares of the experts around her.

"The paper of genuine banknotes has a unique crispness and flexibility to the touch."

Song Qianxia stretched out her gloved fingers and tapped the counterfeit money on the table.

"This banknote feels too rough to the touch."

"In order to imitate the texture of pure cotton, counterfeiters add at least 15 percent synthetic fibers to the wood pulp."

"Of course it's fine for you to use ultraviolet light, because he added a fluorescence quencher."

The veteran experts were stunned and exchanged glances.

Fluorescence quencher?

Song Qianxia continued to contribute.

She pointed to the collar of the portrait on the front of the banknote.

"The textured feel of the real money is created by the actual pressing of an engraving intaglio printing machine."

"Look at this."

Song Qianxia pouted.

"He used an old-fashioned screen printing technique."

"Then we added expanding powder to the ink and baked it in a high-temperature baking machine."

"To create a false sense of protrusion."

"Try scratching it with your fingers; the ink on a real banknote can't be scratched off."

"But the ink on this stuff can be wiped off with just a little bit of industrial alcohol."

Song Qianxia became more and more enthusiastic as she spoke, completely entering her Thousand Faces guidance mode.

"And the funniest thing is the safety line."

She turned the banknote over.

"The security thread on genuine banknotes is embedded directly into the pulp during the papermaking process."

"That guy is something else."

Song Qianxia gave a cold laugh.

"He sandwiched the security thread between two sheets of ultra-thin paper after the paper was formed."

"Then we use high-pressure hot melt adhesive to press them together."

"Although the craftsmanship is exquisite, you can simply soak the money in 70-degree warm water for ten minutes."

"The money will just split in two, and the security thread will fall out on its own."

Song Qianxia finished speaking in one breath.

He didn't forget to give a concluding speech.

"This is hardly a high-tech counterfeit."

"This is clearly an old swindler who knows a little about chemical formulas, cobbling together a shoddy product using outdated equipment from twenty or thirty years ago."

"High precision? I'm ashamed of him."

After Song Qianxia finished speaking, she picked up the bag of steamed buns on the table and prepared to take a bite of the cold bun.

She had just opened her mouth.

I suddenly realized it.

The entire conference room was deathly silent.

You could hear a pin drop.

Several senior experts gaped, their eyes wide as saucers.

He didn't even bother to steady his reading glasses as they slipped off his nose.

Old Zheng froze on the spot, looking at Song Qianxia as if she were an alien.

Gu Tingchen stood to the side, arms crossed.

The man's dark eyes were as deep as an abyss, staring intently at her.

Song Qianxia's action of biting into the steamed bun froze in mid-air.

A cold sweat broke out all at once.

It’s over.

I couldn't control that liar's mouth again!

He just spoke with such professional jargon, clearly explaining the counterfeiting techniques and flaws.

How could a recent police academy graduate who was at the bottom of his class possibly know this?

This is practically like the factory manager personally overseeing the work on-site!

Song Qianxia quickly took the steamed bun away and swallowed hard.

"that……"

Song Qianxia forced an innocent smile.

Where was I?

The old expert with a full head of white hair was so excited that he trembled all over.

He grabbed Song Qianxia's wrist with astonishing strength.

"Little girl! How...how can you tell the synthetic fiber ratio just by touching it?"

"And that expanding powder and hot melt glue."

"You haven't even had any tests done, how do you know so much!"

The old expert was no longer looking at her like she was a young girl; he was looking at her like she was his ancestor.

Song Qianxia felt a chill run down her spine.

His brain was working frantically, and he began to weave a colossal lie on the spot.

"Hey, what's so difficult about that?"

Song Qianxia was talking nonsense with a straight face.

"Master craftsmen, you don't know this."

When I was a child, my family lived next to a large printing factory.

"That printing factory prints textbooks, newspapers, and those low-quality pirated novels every day."

Song Qianxia described it vividly.

"My family is poor. To earn some pocket money, I go to the printing factory's garbage dump to pick up waste paper every day after school."

"Over time, things like paper fibers and ink texture will..."

"I can tell just by touching it with my eyes closed!"

Everyone was stunned.

Old Zheng scratched his head.

"Can you discover papermaking formulas by collecting waste paper?"

"Isn't that a bit too much?"

Song Qianxia immediately straightened her back.

"Captain Zheng, you don't understand."

"That's called specialization!"

"Later, I also often helped the teachers in our village organize test papers."

"Those exam papers printed with inferior ink have raised characters, and your hands will get black if you rub them."

"It feels exactly the same as this counterfeit money!"

Song Qianxia made a solemn vow.

"I love studying, and I'm especially good at math, physics, and chemistry."

"I just figured it out at home, then I bought a few chemistry books and read them, and I understood everything."

She blinked her big eyes, her face full of innocence.

"Actually, it's just that I'm more sensitive to touch, plus a little bit of common sense."

"It's no big deal."

Silence fell over the meeting room once again.

The veteran experts looked at each other, feeling that something was amiss, but they couldn't quite put their finger on it.

After all, they couldn't think of any other reason besides this absurd explanation.

Gu Tingchen suddenly spoke up.

"really."

Gu Tingchen's voice was exceptionally clear in the quiet conference room.

"Practice tactical rolling by shooting balloons."

"Selling grilled cold noodles gave me radar-like hearing."

"Troubleshooting advanced interlocking locks in an escape room."

Gu Tingchen looked at her, a cold smile curving his lips.

"Now there's another one: picking up waste paper with the skill of an expert from a banknote printing plant."

"Song Qianxia, ​​you really have a wide range of interests."

Song Qianxia was terrified by his words.

She could only manage a couple of forced laughs before turning her face away from him.

"Forced by life's circumstances, forced by life's circumstances~"

Old Zheng doesn't care at all how Song Qianxia trained.

All he knew was that there was a breakthrough in the case!

"quick!"

Old Zheng roared excitedly.

"Immediately test the synthetic fiber content of the paper!"

"Follow the clues about this substandard ink and expanding powder!"

"Check if any factories in the city have recently purchased a large number of hot melt adhesive pressing machines!"

The Economic Crime Investigation Team instantly sprang into action, like a wound-up machine.

Song Qianxia took advantage of everyone being busy.

She stealthily moved to Gu Tingchen's side.

"Captain Gu, I've finished all the work."

Song Qianxia muttered softly.

"Can I still go back and eat steamed buns? They're all cold."

Gu Tingchen looked down at her.

The man reached out and took the plastic bag from her hand.

"The steamed buns have been confiscated."

Gu Tingchen turned and walked out.

"Let's go investigate the clues."
