120: Oh no, what kind of new technology is this? How do I replicate it?

However, not everyone could grasp the profound meaning embedded within it.

But that didn't matter.

Solely from the perspective of anti-counterfeiting technology and practicality, this was already more than enough for Su Yu to specifically showcase.

After all, currently, globally, no one had thought of combining a thermometer with paper currency, let alone a paper-based thermometer. Its practicality and significance should not be underestimated!

"Streamer, can you show us? Although we all believe what you say, a thermometer on paper currency is something we've never heard of before."

"What exactly is in Su Yu's mind? He can even think of such an obscure and niche method. First, he showed us the unique dot-image projection technology, and now he comes up with paper temperature-controlled color-changing technology. He's too amazing!"

"When I saw the news report before, my grandpa thought the reporter was exaggerating and bragging, but who would have thought Su Yu was truly incredible."

"Su Yu, quickly demonstrate it for us. I've already started recording, waiting for you to show off."

In the live broadcast room, the audience stared with expectant eyes.

Among them were many foreigners, especially netizens from Meijian Country and Sakura Country, who fundamentally disbelieved Su Yu's words.

Practice makes perfect; only by witnessing this anti-counterfeiting technology firsthand would they believe it. Su Yu looked at the bullet comments on the screen and understood this principle.

Therefore, any anti-counterfeiting technology he mentioned today needed to be demonstrated live, one by one. Either he wouldn't say anything and keep it hidden, or if he did say it, he would openly demonstrate it.

"No problem!"

"I know everyone is very curious about the so-called paper temperature display technology, so without further ado, let's randomly pick one of these four paper currencies to demonstrate for everyone."

Su Yu was not worried about any mishaps during the demonstration, because he had applied this technology to the other three paper currencies as well; it was one of the universal anti-counterfeiting technologies for this set of paper currency.

Soon, at his signal, Host Yan Bingbing jogged out from the side of the stage.

When the girl appeared, she was carrying two large cups of water.

One of these two cups of water was ice water, and the other was hot water with a higher temperature.

Su Yu took the two cups of water and nodded in thanks. Then he turned around again, facing the audience outside the stage.

"As you can see, I now have two cups of water with different temperatures here."

"Now, I will place these two cups of water separately on the 'twenty' and 'fifty'. I will hold this 'one hundred' in my hand the entire time."

"In just three minutes, after the fluid ink comes into contact with objects of different temperatures, the gold powder within it will begin to change."

As he spoke, Su Yu started a countdown on the spot.

Three minutes later... Su Yu first displayed the 'one hundred' he had been holding in his hand.

He held up the paper currency high, and the ultra-high-definition camera promptly provided a close-up shot.

Through the large screen on site, everyone clearly saw the golden dragon paper currency magnified a hundred times.

Inside the gilded 'An' character, the gold powder had already stratified, with the lower layer of gold powder faintly visible and the upper layer showing no signs of shimmering.

And at the boundary between the two, there was a tiny scale line.

"Everyone, look, the scale line at the gold powder's boundary is 37 degrees, which is our normal human body temperature," Su Yu said, then removed the ice water and hot water from the display stand.

"This 'twenty' paper currency was pressed under the ice water for the past three minutes, so its temperature display is at the very bottom part of the 'Tai' character."

"And finally, this 'fifty' was pressed by hot water, and everyone should be able to see that the gold powder has flowed to the upper half of the 'Min' character."

"We can count the position of the scale line upwards from thirty-seven: 54, 55, 56..."

"So the temperature of this water is 56 degrees!"

Beside him, Yan Bingbing had already prepared an electronic thermometer.

As Su Yu gave the answer, she also scanned the temperature of the two cups of water with the electronic thermometer.

Sure enough, the thermometer showed that the hot water's temperature was 56 degrees, while the ice water was only 3 degrees.

Precisely accurate!

Not even a 1-degree temperature difference was wrong!!

At this moment, the netizens in the live broadcast room were completely stunned.

If the previously displayed dot-image projection brought them visual shock, then what the paper temperature display brought them now was a complete crushing by anti-counterfeiting technology!

Ingenious ideas and wild imagination were no longer enough to describe Su Yu's anti-counterfeiting technologies.

In Anti-Counterfeiting Technology Expert's words, this was simply a milestone day in the reform and innovation of anti-counterfeiting technology!

Tears of excitement flickered in the old man's cloudy eyes, and for a moment, he was choked up and unable to speak.

And the currency research experts from Sakura Country were also completely dumbfounded.

"Masaki! This, this is impossible! How can a piece of paper reflect temperature? Is this guy performing magic?"

"Originally, I thought fluid ink was everything, who knew there was something else hidden within!"

"Oh no, Mr. Itada couldn't figure out the dot-image projection technology that kid just showed, and now there's a paper temperature display?"

"If I remember correctly, Su Yu said the complete set of paper currency used thirty-four anti-counterfeiting technologies, and he's only just shown two. Don't tell me the rest of the anti-counterfeiting technologies are all things we've never seen before?"

Ten minutes later.

The Sakura Country research experts were completely convinced.

Because Su Yu's subsequent series of actions were indeed 'shenanigans' they had never seen in their lives.

What about water immersion, fire roasting, laser etching, reverse printing display... The most outrageous part was that, to demonstrate the special nature of the paper currency material, Su Yu connected several pieces of paper currency to a battery and a light bulb at both ends.

The next second, the light turned on!

???

!!!!

This scene directly made the previously confident Sakura Country research expert, who had been spouting nonsense in the Meijian Country live broadcast room, dizzy and faint with anger.

And countless curious netizens, after witnessing the live broadcast 'rollover' of the Meijian Country Currency Research Institute, once again witnessed the collective collapse of Sakura Country's news media.

Netizens in Sakura Country who were following Su Yu's live broadcast were now all wailing with long faces.

Every two minutes, phrases like "Oh no!" "Not good!" "Yamete!" and other such words would appear in the bullet comments.

"I can't watch anymore, I can't watch anymore! If I keep watching, my lungs will explode from anger!"

"Indeed! Is the gap between our Yamato Nation and Huaxia Country really that big?"

"And we still had the nerve to say we broke through their fifth set of national currency? Is this all it was? As soon as they made a move, it was a height we couldn't reach!"

"Oh no, what new technology is this again? How do we replicate it!!"
