The detection of Treasure Ginseng Stone is not simple, especially there are many high-quality Treasure Ginseng Stones, Ling Feng is more cautious. The trunk opened, revealing a lot of tools that he didn't recognize for nine days.

"This is a magnifying glass, this is a laser, and this is a solution for detecting gemstones...... Ling Feng briefly introduced to Jiutian, and the detection of treasure ginseng stones generally comes from two ways: physical and chemical.

As soon as he entered the working state, Ling Feng's attitude became extremely serious and began to test one by one.

While testing, Ling Feng also introduced Jiutian at the same time.

"This purple ginseng stone weighs 17.6 grams, which is considered medium in size. The light transmittance is very good, and the pattern inside is like a flying bird, which is relatively clear. This is a high-quality ginseng stone. ”

Ling Feng said, and also opened a thick booklet, which contained pictures of various treasure ginseng stones, as well as recent quotations. After testing, these can be combined to give a more accurate estimate.

Jiutiangang was still looking at it with interest, but after ten minutes, he began to feel bored. These tests are just mechanical repetitions of movements, which are not fun at all.

Of course, the valuation given by Ling Feng is not the market price, after all, he also wants to make money, and he must be one or two percent higher than the market price to earn the profit from the difference. This is a very normal thing, after all, there is no channel for nine days to directly contact the market.

There are many details that affect the pricing of Ginseng Stone, such as air bubbles, turbidity, and so on. Not every stone is perfect. No one has yet understood the principle of the transformation of the ginseng into the ginseng stone, but some scholars have conducted research and tracked the activities of the ginseng salamander. But all of these trackers failed in the end, and the final location was deep underground.

This shows that Baoshen stone should be a kind of ore located in the very deep underground of Hanhai Park. When the salamander burrows into the ground, it eats these ores. And the effect of ground ginseng is equivalent to an emetic agent.

Of course, this is a more scientific explanation, and there are many things that cannot be explained, such as why the ground ginseng and ginseng stone salamander cannot be taken out of Hanhai Park. There was even a time when someone wanted to dissect a stone salamander. However, when the salamander is damaged, it will decay into ashes in an instant. This peculiar phenomenon comes from the influence of a certain force. It is very likely that the powerful sect that established itself here during the Chaos Period. This is a legacy of power.

"Rare treasure!" Ling Feng suddenly shouted, startled. He turned his head and found that Ling Feng had picked up the Treasure Ginseng Stone that had been made from more than two hundred years of ginseng. The black and white treasure ginseng stone, under the cold light of Ling Feng, shimmered with a strange luster.

"You're going to make a lot of money buddy this time! I just flipped through the information, this kind of black and white ginseng stone is not recorded at present, that is to say, this is a unique treasure ginseng stone, and this head is also very large, 156 grams!" Ling Feng was even more excited than Jiutian, holding this treasure ginseng stone and reluctant to let go.

Although he was very reluctant, Ling Feng finally carefully repacked this black and white ginseng stone into the box, then took it out separately, put it aside, and said: "You must put this treasure ginseng stone well, it is best to find a bank to rent a safe and put it in." ”

This made Jiutian quite surprised: "Don't you want this piece?"

Ling Feng glared, then smiled bitterly, "I really want it, but I really can't afford it." The price of this black and white ginseng stone is many times more expensive than the price of these other ginseng stones combined. I suggest that you auction this treasure ginseng stone, and the price may not be less than 10 million. Hanhai City's ginseng stone is still relatively popular in the jewelry industry. ”

Nima! Jiutian was shocked, he knew that this black and white treasure ginseng stone must be valuable, but he didn't expect it to be so valuable.

The test lasted nearly two hours, and Ling Feng appraised all the Ginseng Stones. Originally, it seemed to be a treasure ginseng stone, but three were sold to Ling Feng before, and there were thirty-seven left. When the black and white ginseng stones were taken out, there were only thirty-six left.

The combined price of these thirty-six pieces was two million seven hundred and thirty thousand, and in the end, Ling Feng gave Jiu Tian a whole price, two million seven hundred and fifty thousand.

As for this black and white treasure ginseng stone, Jiutian decided to entrust Ling Feng to help him sell it, the other party has relevant contacts and resources in this industry, of course, Jiutian has to pay an intermediary fee for this. For this matter, Ling Feng is naturally very happy, and being able to help sell such a piece of ginseng stone is also an opportunity for him to brush his face in the jewelry industry, and can indirectly provide him with a lot of network customers.

Of course, such a large transaction cannot be only verbally agreed, but also signed a contract agreement or the like. It's early in the morning. So Jiutian agreed with Ling Feng to talk again tomorrow afternoon. Ling Feng also has to go back to draw up the contract.

............

The exchange came to the fifth day.

The fifth and sixth days are the last two days of the meeting, and the closing speech will be held on the morning of the seventh day.

The topic of these two days is about large-scale weaving works, and the theme is Hanhai City. Each school has to produce a work, and the top three will be selected at the end.

This time, the lecturer led the team and the students to work together. Although the lecturers of various schools are not necessarily weaving masters, the three stinkers have beaten Zhuge Liang, and no one has an opinion.

Weaving is the forte of the nine days, and since he entered the school in the morning, he has been thinking about what kind of weaving work he wants to make. After thinking about it for a long time, he also came up with a few ideas, but in the end he felt that it was too ordinary, so he crossed it out.

In the end, after thinking about it, Jiutian felt that he couldn't help himself in this matter, so he gathered all the students together for a brainstorming session.

I took the students to apply for a classroom at Hanhai Academy, and then everyone began to discuss the weaving work.

The biggest feature of brainstorming is that no matter how irrational the idea is, it can be proposed. As for whether it can be realized, it is a question later. The principle is to never evaluate or criticize ideas on the spot.

The students were very interested in this brainstorming and rushed to express their ideas.

"I think I can weave an aquarium and weave all the fish in the neighborhood!"

"Seafood! We weave a big seafood!"

"We can freeze the sea water and make ice sculptures!"

"Beauty! There are so many beauties in Hanhai City! How about we make a beautiful 3,000 group weaving?!"

“......”

Jiutian forcibly piled up smiling faces, listening to all kinds of unreliable suggestions from the students. Brainstorming is like that, no matter how unreliable it is, you have to record it. The quantity of ideas is directly proportional to the quality.

Ruan Tang started working as a recorder, and then put forward his own ideas from time to time.
