Liang De pretended to be very skillful and pulled out a hundred-dollar bill from her pocket, he opened the banknote detector, and the faint blue-violet light swept through the group portrait of the laborers printed on the banknote, and finally stopped under the name of the bank.

The colorless denomination numerals on the front of the note glow orange-yellow.

Fluorescence identification is not a very reliable means of counterfeiting, far inferior to infrared penetration, magnetic analysis, laser detection and other methods, the identification of fluorescent numbers can only be regarded as "this is a genuine coin" necessary and insufficient conditions.

But when people come out at night to do shady business, they can't always carry a money detector on their bodies.

Besides, technology can never defeat the soul, and for the illegal trade to succeed, it needs trust between people, not a cold money detector.

"Big brother, don't worry."

The young woman who sold banknotes smiled with a slimy affinity, and the last time Liang De saw this kind of smile was at an eldest sister who was holding a child and selling pirated cassette.

The young woman rolled up her sleeves to reveal a row of plastic-textured NFC labels, the size of a fingernail neatly glued to the sleeve of her undershirt, separated by a distance of three or four centimeters, and the touch of a mobile phone could pay for it.

"Restaurants, clothing stores, cigarette hotel accounts have, more than a thousand I suggest to go to the tobacco hotel, good wine prices are high, a touch is over, sister-in-law asked, said that after drinking, it is okay to give it away, and the custody can not be faulted.

How much do you want to buy? ”

Liang De tucked the hundred-dollar bill back into her coat pocket, and pinched the banknote detector with his index finger and thumb and put it in front of his eyes to examine it carefully.

"This ......"

"Brother, don't worry, the pen must be fine, the brand I bought, you see, there are anti-counterfeiting signs here, it can't be fake."

Liang De still shook his head: "I didn't think about buying money when I went out today, so I didn't bring my own pen, or ...... Are you usually around here? ”

The young woman's smile became a little lighter, she took the money detector in Liang De's hand, pulled on the zipper of her coat and said:

"Brother, let's talk about it next time, let's meet again."

She shook her hair, turned around with her hands in her pockets, and walked briskly towards the alley.

"I'll see you soon, okay."

Liang De looked at her departing back, spread his right hand to make a box of original fried chicken, and a vague aroma wafted out from the gap in the carton, like spider silk on the young woman peddling paper money.

"Lao Liang, you are quite idle, buy it and don't buy it, it will delay other people's time."

Li Zhixian, who watched the whole process, spoke:

"What's the matter with her selling for real money, collectible coins? It's not like that. ”

Liang De ate ate fried chicken, and said in a muffled voice:

"I've been looking into the money thing.

It's not to delay time, I'm just to talk to her more and get married. ”

"Tut-tut, Lao Liang, Lao Liang, you have no one to accompany you on a solo business trip this time, the scumbag's tail is exposed so quickly, no, I think this girl is so ordinary that it can't be described as mediocre, you don't want to."

Li Zhixian shrank back, his expression as if a stinky wet sock was suddenly hanging in front of him.

"Where's your manhood!"

The Thunder Pure Sect 415 World Blue Star Priest said in a shocking voice.

"Solair's radar vibrated just now."

Li Zhixian's expression was shocked: "She is the source of the doomsday?" ”

Liang De shook his head: "It's not her." ”

He crumpled the empty fried chicken carton into a ball and threw it into his mouth, and said:

"The radar didn't move when she followed, and I wanted to make a cameo appearance in an urban legend, but the sudden disappearance scared her, but as soon as I saw the money Suoai radar, I reacted.

It should be that the money, or paper money, has a lot to do with the apocalypse. ”

When Li Zhixian heard this, he clicked on the live broadcast video and rummaged forward.

"Didn't you go to a convenience store in the park during the day, why didn't you vibrate at that time?"

"There was no cash in that convenience store, and I walked all over the park, and I didn't see any cash."

"The level of development of electronic payments here is so high?"

"It's not just electronic payments."

Liang De took out his work tablet and screened the data files he had just been distracted from.

"It's digital currency, digital fiat currency."

In this land, the strategy of fully promoting digital currencies has been implemented for nearly two decades.

The central bank no longer issues banknotes and coins, and continues to recycle the banknotes and coins that have been issued, gradually removing them from circulation.

However, even after two decades, there are still a large number of banknotes circulating in the market, and they are worth more than digital currencies of the same denomination.

The reason is that digital currency is too advanced, it is not only very convenient to use, but also has the attribute of "controllable anonymity", which can meet the regulatory requirements of anti-money laundering, anti-tax avoidance, anti-illegal financing, etc., and the ideological level and moral quality of people in other circles are not worthy of this advanced currency for the time being.

They always want to spend money that they don't want to be known where.

Controllable anonymity is not complete anonymity after all, and the issuer of digital currency and relevant management agencies can detect every flow of funds.

That is, the parties to the transaction can be anonymous to each other, but in the background...... Who knows.

The official has repeatedly reiterated that it will strictly manage and operate prudently, and strike a perfect balance between protecting personal privacy and cracking down on illegal crimes.

But how can those who are thieves believe it?

What they are most afraid of seeing to others is their own consumption records.

So nowadays paper money has become a special commodity, and in some strictly regulated areas, the black market, the exchange ratio of digital currency to paper money sometimes exceeds 1.5:1.

Of course, this kind of behavior is not allowed by the relevant agencies, but it is in high demand and lucrative, and under the severe crackdown on real money dealers, it is still banned.

Li Zhixian finished reading the information compiled by Liang De and said:

"What does this have to do with the end times? You've never even seen cash in the park. ”

"I hadn't thought of the connection between the banknotes and the end of the world, there was a hint of inhumanity on the money, but I didn't smell anything.

The "Lessons from the World" is missing information records for the last 153 years, and perhaps the answer lies in the missing information.

The center of the apocalypse is in the park, but the cause of the apocalypse may be outside the park. ”

Liang De looked at the dark city park in the distance and said:

"Because we knew from the beginning that it was the apocalyptic catastrophe that swept the entire world, our attention has always been on the cosmic environment, the ancient gods and demons, and the international situation.

Brother Xian, have you ever thought that maybe this Blue Star Apocalypse was caused by a very subtle event, so small that we couldn't notice it. ”

"You're saying there's going to be a butterfly effect?"

"I don't know, let's continue to look in the park and see if that butterfly will fly in front of me."
