Police Detective

The car that just passed Bai Song's car was the city bureau's car.

After Bai Song came out, the person responsible for watching at the door understood Bai Song's meaning from Bai Song's eyes.

"This ride is important."

The most taboo thing about following a car is to follow it all the time. It is easy to be discovered. But with three cars interspersed and then using cameras to track, this problem is very easy.

Bai Song also didn't expect that today's situation would really block the clue of possible counterfeit currency - Mian.

Regarding the production of counterfeit currency, the largest counterfeit currency gang in the world is basically concentrated in the field of U.S. banknotes. In the early days, rosin glue was used for sizing paper, which was acidic and not conducive to long-term storage. Later, with the advancement of technology, alkaline sizing was used, so now there is no technical threshold for acid-free paper.

Short-staple cotton, also called cotton linters, is also called cottonseed lint, which is used in industry to extract cellulose.

As we all know, US dollar bills are printed on acid-free paper. But the RMB is different. It looks like paper, but is actually a mixture of short-staple cotton and other natural materials.

In order to investigate this case, the Municipal Bureau also found many cases of counterfeit currency discovered across the country in the past. Basically, they were printed and dyed using ordinary paper. However, some of the counterfeit currency that has appeared on the market recently were printed and dyed using short-staple cotton. Yes, the technology is so advanced that some old currency detectors can be fooled.

Some currency detectors are worse than using human eyes. The human eye can illuminate the upper part of the denomination number with a fluorescent lamp to see whether the fluorescent position is complete and the lines are delicate; the human eye can also see whether the watermark image is perfect by looking directly at the watermark through sunlight.

Some primitive banknote detectors only automatically recognize fluorescence.

On the way back with the car, Bai Song's mind was no longer here.

"What are you thinking about?" The tattooed man asked as he drove the car and saw Bai Song was distracted.

Bai Song was called by the tattooed man and realized something was wrong with him. He simply ignored the tattooed man and immediately began to look at the plum blossoms to quench his thirst.

"Hey, I'm calling you." The tattooed man was a little suspicious and stretched out his hand to push Bai Song.

"Suck it." Bai Song reacted immediately: "It's okay, it's okay."

The tattooed man was speechless when he saw Bai Song almost drooling on the car: "It's only around three o'clock in the afternoon, and you're already hungry?"

"Hey, what do you know? It's not food I'm hungry for. Can't I make four thousand yuan today? This is enough for me to find two girls." Bai Song swallowed.

"You get two for four thousand yuan? So expensive? Where is my C?" The tattooed man also showed an "I understand" expression: "The quality is very high?"

"No, spend two thousand and keep two thousand. If you are blocked by someone, it will give you some relief." Bai Song shook his shoulders.

"I'm telling you, big man, you owe hundreds of thousands, can you get relief with just two thousand?" The tattooed man looked unbelieving: "At least you have to pay out twenty thousand, so we can talk about this, right?"

"Two thousand, that's enough." Bai Song clenched his fists, his joints making a crackling sound: "Anyway, if I say two thousand, you can take it easy, and you can usually take it easy."

The tattooed man nodded enviously: "Yes, if I ask you for an account, I guess I can get two thousand even if I take three or four people with me. I'll talk about the rest another time. It's not impossible."

"That's right," Bai Song said proudly, "but it won't work without a penny. Giving two thousand is just a matter of face. But, having said that, are there many jobs like this here? Is there any job that pays faster? ?”

"Isn't this fast enough? In addition to the reward from the boss, you also have two thousand yuan this day. Now you go out to do odd jobs and can only earn two thousand yuan a month."

"Working?" Bai Song glanced at the tattooed man, seeming to despise the word.

"I'll just give you an example. If you work hard here, you will still have enough to eat and drink." The tattooed man felt that he was getting old. He was obviously a bad person, but why did he become a good person in front of Bai Song?

"The most I ever won was 190,000 in one night." Bai Song was a little excited when talking about this.

The tattooed man sneered slightly. He also played with money, but in the past few years, he could make money in the transportation company, but he still rarely played that big.

It doesn't matter how much money you win from gambling, it's all about probability. The more you gamble, the more you lose.

The initial probability of winning or losing is 50% for gambling. Because there is a 10% rake for winning money, you must maintain a winning rate of more than 52.381% to avoid losing money.

What is this concept?

Play 10 games, the probability of not losing money is 50%;

Play 20 games, the probability of not losing money is 25%;

Play 50 games, the probability of not losing money is 12.5%;

Play 100 games, the probability of not losing money is 1.57%;

Play 1,000 times, the probability of not losing money is 0.00000000000003%;

Play 10,000 games, well, it’s too clumsy to write.

The most important thing is, is there any gambling with a 50% winning rate? Even if the casino does not cheat, the winning rate is generally between 40% and 48%.

Some people can achieve a winning rate of about 53% through actuarial calculation of cards, but in the face of rake, they lose nothing in the end, and some do.

You can still win by gambling for a long time, which is no less than winning the first prize by buying lottery tickets continuously.

Gamblers all know this truth, and it is too common among gamblers to laugh at a hundred steps.

The tattooed man had lost a lot playing cards over the years, but he knew that Bai Song had lost 270,000 in one night a few days ago, so he felt that Bai Song was a big fool.

What's the use of winning 190,000? Isn’t it enough to fill the hole in the end?

The tattooed man had an inexplicable sense of superiority and said, "So how much money do you have now?"

"It's okay." Bai Song's smile didn't diminish: "I'd like to talk about you guys. Although someone said during lunch that most of you have been in the army (and been in prison), but now you have to be honest for this little money. I said, our boss is not a simple person, he is a person who does big things. It won’t take long for me to follow the boss and do better than you."

The tattooed man was not happy to hear this. The newcomer's ability to stay here had a lot to do with him. Why was he so stunned? Don’t know how much you weigh?

"The water here is deep, where can you see?" The tattooed man said insultingly to Bai Song.

"What do you know?" Bai Song hammered the car door with his fist, and the car door banged: "I used to sell hustlers in the Ganning area. Do you know how much a trip to that thing costs? I've asked a lot of questions. People who understand, anyway, if I am caught, I will leave the team. As long as I am shot less than once, there is nothing in the world that I dare not do! Let me tell you, I dare to earn and spend, two thousand yuan to play at night One night is nothing, I have spent sixty or seventy thousand for fun in one night, have you ever seen it?"

The tattooed man is usually very aggressive in the transportation company. He bullies Xiaohou and Wang Huadong very easily. But now when he encounters Bai Song, a tough guy like Bai Song, he really can't control himself.

This is a bit embarrassing

The tattooed man looked at his flowered arms, and then at Bai Song’s bald head.

Actually, am I a good person?
