"President Du!"

At the moment when Nanli was concentrating on opening the stone, three or five male classmates rushed over. Obviously, it was Du Jinsheng who called for help.

"Why are you here? Du Jinsheng complained, but his face was happy, and he said, "This stall owner sells fake jadeite rough stones, and we are betting on it." You're going to have to give me a shot!"

"Isn't this a woman, Nanli?" one of the chubby boys recognized Nanli.

"Do you know her?" the tall boy next to him looked at him in surprise.

"yes, didn't she just join our treasure society? our boss still praises her..."The fat boy introduced.

"Shut up. Du Jinsheng snorted, "I didn't agree to her joining the club." ”

Du Jinsheng's reaction made the few people who had just arrived very puzzled, it was not a popular club in the first place, and it was not easy to recruit new people, why did they disagree? and she was a good-looking girl.

At this time, Nanli turned off the machine, and there was no joy or sadness on his face, but he looked at me suspiciously. I was embarrassed to look at her.

"It's open. "Hey, it's over. The crowd saw that the machine had stopped spinning and became agitated.

Du Jinsheng, who had just been distracted, also turned around and gave orders to the classmates of the treasure appreciation club who had just arrived: "Shhhhhh No matter what, you'll have to support me!"

Nanli slowly stood up and didn't say a word.

Everyone was anxious and asked, "How is it?" "Is there any jade?" and "Is it worth it?"

"Students, that's right, now the material has been opened. But what the result, I say, or he says, everybody is hard to believe. Are there any classmates or friends who know how to appreciate jadeite, come out and give an objective review?" Nanli calmed down everyone's quarrel and said loudly.

But among the people present, not a single one came out to respond.

After a while, a vigorous and powerful voice remembered, "Classmate, how about you let me see?"

Looking at the voice, it was a thin little old man with a pair of gold-rimmed glasses, very elegant. I felt a little familiar, but I couldn't name it.

"Professor Zheng. "Dean Zheng is here too!" There was no shortage of classmates in the crowd who knew this little old man.

Professor Cheng greeted the students cordially. Everyone consciously gave way and guided Professor Zheng up.

Nanli looked at Professor Zheng blankly, although his sudden big eyes looked cute, but he was a little rude.

I hurriedly stepped forward and whispered, "This is the vice dean of our Faculty of Arts, Professor Zheng." Experts in the identification of collectibles, not to mention our school, our collection circle is very famous. ”

Although my voice was not loud, Professor Zheng heard me and asked me with some curiosity: "Oh, this classmate knows me? Did he take my class? Which college?"

This question poked at my soft underbelly, I scratched my head, and said embarrassedly: "Dean Zheng..."

Professor Zheng shook his head, waved his hand, and said, "You can call me a teacher or a professor, I don't like students to call me an administrative position." ”

"Professor Zheng. I signed up for your electives. I said timidly.

After listening to this, Professor Zheng wondered who I was, but to no avail.

I continued, "However, I didn't go that day because of something at home. ”

My words made everyone understand, and I blatantly skipped class in the first class!

The laughter shook the sky, and I blushed a little for a moment.

"Hehe, that's right. That classmate, you are going to come in the future, I remember you. Professor Zheng was also amused by my words and hurriedly said.

Seeing that I was embarrassed, Nanli hurriedly greeted. "Professor Zheng, then I will rely on you to give justice!"

"Ouch, this classmate, don't dare to support justice. I'm just here to show the jadeite. Professor Zheng said modestly. Then, he picked up the cut jade rough and looked at it.

"Iron Dragon. Professor Zheng judged the variety at a glance.

Everyone turned their heads to each other, talking about what Tie Longsheng was.

Next, Nanli's booth became Professor Cheng's three-foot podium.

Professor Zheng said: "Students, Tielongsheng is a variety of jadeite, which means full green in Burmese. Then he held up the jadeite and gestured: "Look, the green of this jadeite is very gorgeous? This green is mainly a kind of jadeite with chromium as the color-causing element, with a dense structure and poor water head, which is composed of chromium-rich jadeite mineral aggregates. The minerals are mainly jadeite accounting for more than 95%, followed by chromium, town, calcium, iron, etc. From a gemological point of view, the main mineral component of Tielongsheng is sodium chromium pyroxene

Eyite monoclinic pyroxene group of mineral gemstones. chemical formula

si2o6。 This mineral is an extremely rare jewel in nature, and the traditional entrance is Longken. ”

Professor Zheng's words are very attractive, and some of the students below took out paper and pen to make notes, and some were busy taking pictures to record such a vivid teaching scene.

"Professor Zheng, tell me about the specific situation of this piece of jadeite in your hand. The students in the audience listened to it and asked about the example.

Professor Zheng smiled and said to everyone: "I must talk about this fast jadeite." ”

Then he turned around and asked Nanli, "Classmate, is this stone yours?"

Nanli nodded, then shook her head again.

Professor Zheng did not get entangled, and continued: "This iron dragon is born, the color is emerald green and uneven, the grain is coarse, opaque, white flowers, and cracks, which is the lower grade; the color is all emerald green, translucent, the grain is fine and medium-grained, the water head is 1 point, it is the middle grade, the color is all emerald green, similar to the first grade, it is a micro-particle aggregate, and the transparency is slightly lower for the upper grade." ”

Professor Zheng paused and continued: "And this piece of jadeite can be described as superb. ”

As soon as these words came out, everyone immediately boiled.

Professor Zheng maintained order and said, "Listen to me." The color is all emerald green, high transparency, microscopic granular aggregates, delicate jewelry, 3 points of water head, white flowers, no cracks. ”

Du Jinsheng suddenly interrupted Professor Zheng's explanation: "Teacher, this iron dragon is not of high quality and has a large output, how can it be such a superb? ”

Professor Zheng waved his hand to stop and said, "I understand what this classmate means. This piece of jadeite rough should not be from Longken, but from Pakan. Let's put it this way, with my eyesight, although I can't say 100% right, at least it's certain, it's a piece of jadeite rough. Moreover, it is also a high-quality jadeite rough. ”

After hearing this, I immediately admired Professor Zheng and sighed that this is the real knowledge!

Zhu Chen shouted next to him: "The surname Du, apologize, apologize." ”

Naturally, we all understood, and coaxed: "Apologize, apologize." ”

Du Jinsheng's face was full of shame, gritted his teeth, and did not spit out a word.

At this time, Professor Zheng, who did not understand the situation, was also a little embarrassed, and persuaded him: "Students, you have to be forgiving and forgiving. Leave room for others. ”

"You don't know, just now he forced this female classmate to be embarrassed. We are a tooth for a tooth!" Sun Wei said mercilessly.

Professor Zheng was a little displeased, so I hurriedly stepped forward and said, "Students, the eyes of the masses are bright. Now we are all justifying Nanli's name! He is not a liar! This matter, let's let it pass like this, let's ask Professor Zheng to talk about the market value of this jadeite!"

As long as it is related to money, it will attract everyone's attention after all.

Professor Zheng said, "Oh, that's a really difficult question. I'm not very good at this market valuation. But this girl, you'd better keep him in the bank. Because the value is at least more than 400,000. ”

Nanli came from a jadeite family, and he had already estimated this piece of jadeite, but he was not shocked. But the crowd of onlookers was really surprised.

Nanli said indifferently: "Professor Zheng, this rough stone belongs to him. Then, he pointed to Zhu Chen next to him.

Zhu Chen was really startled, and hurriedly shouted: "No, no, this is Niu Ben's." Niu Ben, Niu Ben. ”

I was shouted with a little headache and said, "It's here, it's yours, don't call me." ”

Professor Zheng's eyes lit up and he asked, "Are you Niu Ben?"

I was surprised, but the answer was yes.

"Haha, I didn't expect that the college student Lao Ji said was actually from our school. Professor Zheng burst out laughing, very heartily.
