Chapter 6

"Lose money!" The man stands in front of Lin Lu, his face is ferocious and roars.

"Yes, lose money!" There are also many people in the crowd who are not too big to watch the excitement and start to make noises.

Lin Lu's eyes are slightly red. She has no way to deal with it. She doesn't know what to do. It's too bad for her now. There's no end to losing money. But if you lose money, isn't it obvious that the responsibility is in your shop? Now even the TV stations are coming. This negative effect will let the whole city know that things will not only lose their reputation, but also the compensation will not work at all.

What should we do?

The voice of losing money in the crowd is louder and louder, including many peers around who are secretly involved. This is the so-called peer is the enemy.

Yao Shengwei didn't know what to do. He wanted to help, but he couldn't do it. He couldn't get five million.

At this time, a not very tall figure stood in front of Lin Lu, separated her from the people who denounced her, and blocked all the wind and rain for her. The voice was smooth, and said word by word: "that night pearl is a fake."

"What?"

Everyone looked at the figure with consternation, and scolded this guy in his heart for being stupid, right? Dare to question Master Zhang's appraisal. Master Zhang is the most popular antiques expert in the city. How can he identify something wrong?

Even Lin Lu and the old shopkeeper were stunned.

Yao Shengwei is more indignant, shout: "in the middle of the week, you add what chaos!"

The figure standing in front of Lin Lu is Zhou Zhong!

Zhou looked at Yao Shengwei faintly without paying attention to him. Then he said to everyone again, "the Pearl of the night is a fake!"

This time, a flurry flashed in the eyes of the troublemaker's man, but he immediately felt that Zhou Zhong was a child. What can he do? And look at Zhou Zhong wear a rag goods, dirty, immediately disdain angry voice scolded: "where do you come from? Brick resistant in the construction site? Do you understand antiques? Go back and play with your cement

Master Zhang also frowned and said in a very angry voice, "boy, the curse comes from the mouth. Do you know that? You dare to question my identification of the goods, today or you will tell me this thing clearly, where is the night pearl fake! If you don't understand, I'm not finished with you! "

People nodded one after another, thinking that Zhou Zhong was just coming to make trouble. What can a bumpkin understand when he looks so shabby?

"Thank you in the middle of the week, but you can't help it." Lin Lu was grateful for Zhou Zhong's coming forward, but she couldn't handle it. Zhou Zhong's coming in would only involve him. Lin Lu didn't want to implicate Zhou Zhong, so she whispered to Zhou Zhong.

"It's OK. Don't worry." Zhou Zhong looks back and gives Lin Lu a confident smile.

Lin Lu was stunned. It seemed that she had never seen such a week. In the past week, I was a little self abased, and I was silent when I was in the class. I spent most of my time reading by myself and would not play with my classmates. Some class activities were also avoided as far as possible.

But today's week seems to have changed, and before that self abased, introverted, closed self week is completely different!

Zhou Zhong looked back at Master Zhang and said, "if I say that night pearl is false, there must be a basis."

For a moment, people were surprised. Did the young man dare to say that there was evidence to prove that the night Pearl was false? Are you kidding? What kind of antiques can he understand at that age?

At the moment, even the TV reporters are interested in Zhou Zhong. They quickly ask the photographer to shoot at Zhou Zhong to see what he will do next.

Zhou Zhong walked towards the fragments of the night pearl, then squatted down and picked up some of them. He played with a confident smile in his hand for a moment. He looked back to the camera and all the onlookers and said faintly.

"The night pearl, as we all know, is formed by the accumulation of some luminescent materials in the earth's earth after thousands of years, from the initial volcanic eruption to the later geological movement. According to historical records, it first appeared in the period of Emperor Yan Shennong. "

After a pause, Zhou Zhong continued: "the luminescence of night pearl mainly comes from phosphor, which is divided into permanent luminescence and long afterglow light storage type night pearl. It does not need any external energy, but relies on its own activators, such as 14C, 3h, 147Pm, 226Ra, 232Th, and other radioisotopes, to emit light by itself. "

"The long afterglow luminous night pearl, the activator in the phosphor is not radioactive, and it can only emit light after being excited by sunlight, ultraviolet and other light sources. Nowadays, there are more than 100 kinds of phosphors in common use, and their chemical compositions are all second-order metal compounds except alkali metal halides, such as sulfide, selenide, telluride, silicate, aluminate, tungstate, phosphate and halogen phosphate

-

all the spectators, Lin Lu, the old shopkeeper, Yao Shengwei, and the TV reporters, including the two troublemakers and master Zhang, were all dumbfounded.In particular, Zhou Zhong didn't use any foreign things, a lot of chemical substances blurted out, looking at the light cloud, it was just handy. Many people don't believe in evil. They think that Zhou Zhong is boastful, so they turn on their mobile phones to check information on the Internet. They are scared to take it. Zhou Zhong's words are not bad.

In the middle of the week, regardless of these people, he continued to talk: "to distinguish the authenticity of the night pearl, there are the following points. First, the night pearl must be illuminated for 15 minutes, and it can emit light continuously for dozens of hours. Second, it has phosphorescence,. Third, beautiful color, translucent, without any light, both permanent active light, and large amount of light. Fourth, the fluorescence and phosphorescence of fluorite must be distinguished. The phosphorescence phenomenon is that under the action of external light source, the phosphorescence can keep a certain luminous time after being removed. The length of the fifth luminescence, the length of its half-life, and the length of its afterglow

"Now most of the cost of the night pearl on the market, mostly use the luminous effect of fluorescein or phosphor to create the illusion of luminous night pearl. To distinguish the true from the false, we only need to distinguish whether there is fluorescence, or the marks and cracks left after filling with fluorescein or phosphor, which is easy to distinguish."

In the face of Zhou Zhong's talk, the troublemaker felt that the situation was not right, so he could not let him go on, so he made a decision and yelled: "boy, you stare at your dog's eyes. The Pearl of our night is not fluorescent, and there is no trace of filling. Can you understand such a simple thing, Master Zhang? You want to show off here? "

People were originally deceived by Zhou Zhong, but after listening to the man's words, they nodded one after another, and felt that what the man said was reasonable. It was impossible for Master Zhang not to know such a simple identification method.

However, Zhou Zhong did not change his face. He still looked calm and confident, holding the fragments of the night pearl in his hand, he said: "yes, if it is a simple forgery, the so-called master Zhang can naturally identify it. However, I have to admire you. You are really smart. You should add a kind of substance to the phosphor that can comprehensively dilute the phosphor and make it emit light continuously for a long time. This substance is a synthetic product, including fluorescence, and the water light body extracted from some fish luminous organisms. "

"So it can emit light for a long time, and it's hard to detect any sign of fluorescence!"

After listening to Zhou Zhong's words, the old shopkeeper suddenly realized and said, "ah! I said, how do I feel that the night pearl is a little strange. It meets all the special requirements of the night pearl, but I always feel that it's not right. I can't tell what's wrong. It's such a thing

For a moment, people were suspicious, but at this time, the big man who had never spoken suddenly asked his companion angrily, "Lao Guo, didn't you say that this is your exclusive invention, and no one can see through it?"

……

Everyone's eyes are wide open. It's Is that really the case?

"Waste! Don't talk nonsense. What exclusive invention is the night Pearl! Don't listen to his nonsense The troublemaker quickly sophisticated to cover up the way.

Zhou Zhong chuckled faintly and said lightly: "is this a simple thing? As long as you take it to the material identification center to identify the ingredients contained in it, it will be clear at a glance."

The next two men are a little flustered, turn around to run.

Coincidentally, two policemen arrived just in time to intercept the two men.

"We suspect that you two are suspected of cost fraud. Let's go back to the Institute." The two policemen said with cold faces and caught them directly.

The two policemen were Lin Lugang who saw that things were not right. They secretly called the police, but they really came in handy.

For a while, people began to talk about it, and they were excited to point to the middle of the week. They didn't expect a big reversal. The troublemaker duo, who had already occupied the absolute advantage, was directly exposed by such a seemingly insignificant young man.

Isn't this young man so wonderful? Look at the way he just picked up a lot of professional knowledge. He was a master of antiques. Even the night pearl that master Zhang didn't identify was identified by him.

The master's face turned red at this time, but he didn't expect that the Pearl of the night was really fake. It was like hitting his face. Suddenly no face to continue to stay here, while people do not pay attention to the crowd ran.

"My God, mid week, you How did you do it? " Lin Lu looks at Zhou Zhong like an alien at this time. Zhou Zhong's performance just now completely shocked her.

She never imagined that Zhou Zhong had such a deep research on yemingzhu. At the same time, she was very grateful to Zhou Zhong. If it had not been for Zhou Zhong, the antique shop would have suffered.

As early as Zhou Zhong saw the fragments of the Pearl at first sight, the treasure finder had already listed the ingredients of the Pearl, and directly identified two words - counterfeit!

But these things naturally can't say in the week, just low-key said: "I've read this kind of book before, did not expect to really use it."

"Well, a blind cat meets a dead mouse." Yao Shengwei quite envious in the side cold hum way.

At this time, a gray bearded old man came out of the crowd and said to Zhou Zhong with eyes full of appreciation: "little brother, your performance just now really brightens the old man's eyes. This is my business card. If you encounter anything in Jiangling, you can come to me."Zhou Zhong saw that the other party was very old, respectfully took the card, and then rather embarrassed said: "old man, I don't have a phone."

The old man said with a smile: "when you have a phone call, you should tell me the first time."

"Yes, certainly." Zhou Zhong nodded and agreed.

The old man nodded to Zhou Zhongdian again and then turned away.
