78: Oh no, have I become an accomplice?

There are actually many methods for authenticating currency.

Xiao Changchun could explain all the relevant knowledge about domestic currency in one go, and he also basically understood the anti-counterfeiting technology of the US dollar.

The micro-printing technology on the security thread is considered very difficult among anti-counterfeiting technologies.

This is because it involves both character micro-printing and the reflective color-changing properties of the security thread, and finally, it needs to be perfectly integrated into the banknote.

Any one of these elements, taken individually, would have a difficulty comparable to color-changing ink.

It wasn't that Xiao Changchun looked down on Su Yu, but rather that the people who could truly master all these anti-counterfeiting technologies were indeed few and far between.

Otherwise, the counterfeit banknote Su Yu initially displayed should have had this anti-counterfeiting technology.

"Hmph, what did I tell you? How could this Young man possibly counterfeit a US dollar?"

"Officer Xiao just said that he had never seen a security thread on the counterfeit banknotes."

"Just by the name, this thing sounds very secure."

"Security threads are too difficult; ordinary people simply can't make them. It's understandable that the Streamer opposite can't do it; if he really could, that would be a miracle."

In Xiao Changchun's live stream, everyone was relieved that their Streamer was able to regain his composure.

After all, if such a famous anti-fraud Streamer couldn't identify even one issue during a live stream, it would indeed have a significant negative impact on him.

At this moment, Xiao Changchun was calm and confident of victory.

His previous 'failure' actually had an element of performance. Although the other party's counterfeiting technology was indeed impressive, he wasn't completely unable to distinguish it.

Now, even for anti-fraud promotion, live streaming requires a good show.

If there's no reversal, no grand finale, no plot in the live stream, who would want to watch you?

Xiao Changchun's question was within Su Yu's expectations.

After all, the other party was a professional anti-fraud police officer, and he must frequently deal with currency.

The security thread was a reward the system later issued to him, and it was also one of the anti-counterfeiting technologies he planned to produce live tonight.

Since the other party brought it up, he felt it was time to show it.

"Officer Xiao, you are right."

"This counterfeit semi-finished US dollar indeed does not yet have a micro-printed security thread." Su Yu admitted his shortcoming without hesitation.

Xiao Changchun nodded with satisfaction upon hearing this, just as he was about to say a few polite words and simultaneously popularize anti-counterfeiting knowledge about security threads to his fans.

Su Yu's subsequent actions, however, made him swallow his remaining words.

"But it doesn't matter."

"The Brothers in the live stream should also know that I was prepared before starting tonight's broadcast."

"If there's no security thread, then we'll make one live."

"If the Brothers want to know the specific production method, be sure to keep your eyes wide open and watch every step carefully; the Streamer will only demonstrate it once!"

As his voice fell, Su Yu adjusted the live stream camera, pointing the lens at his hands.

"I'm dying of laughter, 'make it live'? Who do you think you are?"

"Exactly, exactly, he's too arrogant, 'watch carefully, only demonstrate once,' so pretentious, I want to see what you actually..."

The bullet comments hadn't even fully floated by.

Su Yu had already started working under everyone's watchful eyes.

A pile of professional machines and materials appeared in front of the camera; these were all the various tools needed to create a micro-printed security thread.

As Su Yu used these tools, the knowledge in his mind automatically surfaced.

In just a few minutes, a translucent, colorful security thread shimmering with various characters had already been made by him.

???!!!

Seeing this scene.

Xiao Changchun was completely stunned.

No, he's really making it live?! No joke?

And his fans in the live stream were all agape at this moment, so shocked they could have swallowed their fists.

This, this... what kind of operation is this?

Just like that, he started making a currency anti-counterfeiting security thread?

It couldn't be more fantastical!

The key is that you make it so easily, it makes all of us feel like 'I could do that too.'

"Alright, Officer Xiao, do you see if this security thread is as you described?"

"If there's anything I did wrong, just tell me directly, and I'll redo it."

Su Yu placed the completed security thread in front of the camera, humble and modest.

Because the security thread is originally hidden inside the banknote, after completing its production, he then found a way to re-integrate it into the semi-finished replica US dollar.

Xiao Changchun opened his mouth, and for a long time, he said nothing.

He had connected with so many Streamers.

There were many with talent and skill, and many with hundreds of thousands of viewers online, but Su Yu was the first person to make him doubt his own professional ability.

He, a dignified anti-fraud Streamer, was powerless against a counterfeiting Streamer.

It wasn't that he was powerless.

It was that if this guy didn't say anything about the things he replicated, he truly might not be able to distinguish them.

Hand-drawn patterns, color-changing ink, watermarks, even micro-printed security threads could be made live.

Looking at it this way, what anti-counterfeiting technology could possibly stump him?

Facts proved.

Over the next two hours, Su Yu indeed did not disappoint him.

Xiao Changchun racked his brains, pouring out every US dollar anti-counterfeiting technology he knew.

And with each one he mentioned, on the other side of the camera, Su Yu's eyes lit up a little more.

Intaglio printing, micro-characters, red and blue fibers... Xiao Changchun would mention one, and Su Yu would immediately take out tools and begin replicating it. His movements were effortless, as if the memory was etched into his bones.

Until the very end, even Su Yu's own fans in the live stream became numb.

Numb.

They were truly numb from watching.

If it weren't for his personal homepage, where the blue V verification clearly stated that Su Yu was a genius researching in the aerospace field, everyone would probably think this guy was a professional counterfeiter, right?

Otherwise, how could all sorts of currency anti-counterfeiting technologies be rendered useless in his eyes?

..."Alright, Officer Xiao."

"Do you see anything else that needs further improvement?"

Stopping his movements once again, Su Yu placed the modified US dollar back in front of the camera.

The black-green ink on the acid-free paper emitted a faint scent of ink.

In the live stream.

Two completely identical US dollar banknotes appeared before everyone's eyes.

Even Xiao Changchun was stunned at this moment.

Who would have thought that all the techniques for distinguishing counterfeit money he had just discussed ultimately served as a bridal gown for Su Yu's replicated US dollar?

Looking at the meticulously replicated US dollar in front of him, Xiao Changchun's heart couldn't help but panic.

If.

If this counterfeit US dollar eventually circulated, Su Yu would naturally be the principal offender.

And he, who had provided so many anti-counterfeiting technologies, wouldn't he become an accomplice?
