"Secondly, try to find walnuts with the same tree and branches, generally a batch of walnuts down, walnuts of the same tree are often more similar in shape and texture, some walnuts are branched, and the walnut farmers usually retain their original branches when they are removed, so that a pair is easier to approach in shape and size......"

Yuxi was talking, but before he finished speaking, he was interrupted by Liu Wal next to him: "Okay, don't think I don't know anything about betting on walnuts, I also know what you said, but no matter how much you say, it's just talk on paper without actual combat, so I can give you a chance." Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ”

As soon as he heard the word "opportunity", Yuxi's eyes lit up a little, and he hurriedly said, "Brother Liu, just say it." ”

Liu Wal said: "In this way, you will buy a pair of green skins to gamble, I don't care what the texture is, as long as the size is the same, then I will ......."

Yuxi couldn't wait to say, "If I win the bet, can this old elephant skin be sold to me?"

Liu Wal shook his head: "Impossible, I said that I wouldn't sell it to you this time, but I can bring you a piece of the same next time." Of course, you can also say no. ”

"I promise!" Yuxi agreed, if he didn't agree at this time, it would be a problem with his brain.

Liu Wal smiled: "It's a good thing to have confidence, but if you can't gamble for a while, then you can go back honestly for me." Plus, you only have one chance, and if you fail this time, you'll automatically throw in the towel. ”

"You can rest assured. Yuxi patted his chest, although he didn't bet on Qingpi a few times, the only few times the results were very good, so he was also very confident in himself.

Anyway, there was nothing else, everyone squeezed into the crowd and entered the ranks of the pickers, Meng Zitao looked down, the green skin here did not look fresh, in fact, this is a normal thing.

The walnut tree time is theoretically generally in the summer to the white dew backwards 1 to a few days of this period successively under the tree, generally in the Gregorian calendar in August and September, of course, due to the different geographical location and the characteristics of each tree species are different tree time early and late.

It's mid-November, though, so the walnuts here must have been refrigerated to keep them the way they are.

Meng Zitao couldn't help but shake his head secretly when he saw that many people were choosing their favorite green skin walnuts, because these people may not know much about gambling on green skins, and they also ignored some of these problems.

Gambling on green skin is actually like the jade rough, relying solely on the appearance of observation, it is difficult to judge how the walnut in the green skin is color, how big it is, many of the green skin that has just been peeled off the tree has not been peeled, and it is directly put on the stall, a twenty or thirty, want to make money and gamble on the stone, are dependent on the buyer's eyesight and luck.

Compared with the jade gambling stone, the green walnut is a fruit, so it has the characteristics of the fruit, for example, there will be a shrinkage process after the walnut is off the tree, and people who generally know about it know that the size of the tree shrinking in a month should be the largest, about 1mm, but in addition, there is a greater risk of walnut harm in this month, and there may not be many people who know, that is, "cracking"!

Because this period of time is the time when the dryness and humidity of walnut cortex change the most, the process of drying and shrinking causes uneven density of walnut cortex, and the dry shrinkage degree of different thicknesses is also different, so 98% of walnut cracking is within this time.

You see that there are so many people who gamble on green skins every year, but how many pairs of them are left to play with old walnuts? It is not an exaggeration to say that it is "a drop in the bucket" and "rare".

From October to December every year, the dry shrinkage period of walnuts has passed, and the direct size of walnuts can be seen almost when you buy them, and you can also observe the cracking.

So it stands to reason that it is a good time to buy walnuts now, but the crux of the problem is that these walnuts will undoubtedly delay the drying time after refrigeration, so buying green walnuts here will also face a problem of shrinkage and cracking.

The cracked walnuts are basically scrapped and can't be played at all. But looking at the crowd of people around gambling on green skins in front of them, how many of them understand that this walnut is basically a waste when they buy it back?

Of course, none of this has anything to do with Meng Zitao, since you want to bet on Qingpi, you should be prepared to lose all your money, and the price of dozens of yuan is not expensive, and in the end, even if the gamble collapses, it is nothing. Of course, if you choose a pair of green-skinned walnuts that cost thousands of dollars next to you, it will be a little painful if you gamble.

Getting back to the point, Meng Zitao looked to the side and found that Lao Niu was also there, and Lao Niu also saw him, and was nodding to himself with a smile.

Meng Zitao also smiled at him and motioned for him to continue to pick green-skinned walnuts, and he joined the selection himself.

Meng Zitao's bet on walnuts was actually more theoretical, and he really hadn't started the actual battle, so when he picked a few pairs of walnuts, the ability didn't give a good result, so he simply used the ability. It turned out to be a big disappointment.

On the other side, Yuxi lowered his head to pick his favorite walnuts, and kept muttering in his heart about the number of walnuts to choose.

"The most important thing in choosing walnuts is whether the shape is consistent and correct. When picking, place a pair of walnuts horizontally and observe the position of the umbilicus. If both are in the center, the tip of the walnut may be more positive, and if one is positive and the other is off, the pairing may not be perfect. When choosing a core, it is best not to take the risk of picking a crooked one, which increases the risk of losing the bet...... There you have it, that's it!"

Yuxi looked at the pair of green-skinned walnuts in his hand and was overjoyed, so he asked the stall owner about the price.

"Boss, how much is this for walnuts?"

"Three thousand. The stall owner glanced at the walnuts in Yuxi's hand.

"Why is it so expensive!" Yuxi frowned.

"If you want to be cheap, choose this one. The stall owner pointed to a pile of green-skinned walnuts next to him, which was obviously not as good as his performance, and his attitude did not look very good.

"Can't it be cheaper?" asked Yuxi.

The stall owner directly refused, and no longer talked to Yuxi, and talked to another customer.

The attitude of the stall owner made Yu Xi angry, but there was no way, he had to buy it now, and he could only pinch his nose and admit it, but fortunately, with the performance of this pair of green-skinned walnuts, three thousand yuan was not expensive.

After paying the money and completing the transaction, the stall owner's attitude finally improved: "Do you want to open it now?"

Yuxi immediately said, "Give it to me now." ”

The stall owner nodded, and immediately used the tool to open the walnuts, and the speed of opening the walnuts was very fast, and the first one was opened immediately.

"What a big walnut, what kind of variety is this?"

"It should be a unicorn pattern official hat, the size is estimated to be more than 46. ”

"Wow, it's so big, it must have gone up. ”

"Brother, you don't understand, this unicorn pattern official hat is native to the deep mountains of the Taihang Mountains, belongs to the wild species, and there is only one mother tree, which was introduced from the wild by a villager named Wang Yong in 03. Later, the artificially cultivated walnut came on the market, because the variety is extremely rare, not known to outsiders, and because of its large size, peculiar texture, rough and beautiful and bright color, it was quickly sought after by players, and people rushed to cultivate. ”

At that time, this walnut had no name, because it was discovered and cultivated by Wang Yong in the wild, so it was called Wang Yong's Daguan hat (word of mouth, Yongyi Yong is also brave). Because the walnut texture resembles the scales of China's traditional Rui beast unicorn, it is also known as the unicorn pattern official hat, and has quickly been recognized and respected by many players. In the past few years, the Kung Fu Kirin Daguan hat has become a famous product sought after by many players and has become one of the most popular cultural toys. ”

"But because it is generally large, it is more common to have more than 46, and in addition to the size and performance, walnuts also have to look at the pairing, otherwise even if they are large, it is unlikely to be sky-high. ”

While speaking, the stall owner measured the size of the walnuts with vernier calipers, and finally had some smiles on his face: "49.2." ”

Although the unicorn pattern official hat is more common in size because of the variety, it is still quite rare to have a size above 49, and Yuxi couldn't help but smile on his face.

But then again, although the size of this walnut is big enough, but the texture can only be said to be average, with the current 09 market, the price is about 5,000, unless it can be paired, otherwise it is impossible to be higher.

Yuxi suppressed the excitement in his heart, a walnut is nothing, now he needs a good pair, and because of the large size, he is even more stressed.

As the old saying goes, walnuts are: "It is difficult to pick one in a hundred miles, and it is difficult to become a pair for thousands of miles", the characteristics of walnuts are determined, only the walnuts are paired, the rarer the variety, the larger the size, the more perfect the quality, the higher the collection value!

As a result, the result of the second walnut made Yuxi want to cry without tears, just like Meng Zitao said before, the walnut that opened was cracked, and the size was only 46.

"Brother Liu, can you give me another chance?" Yuxi said with a sad face.

Liu Vol said lightly: "Manly man, a mouthful of spit and a nail, since you have made a bet, how can there be any reason to regret it, don't let me look down on you!"

Hearing this, Yuxi didn't dare to say anything more and left extremely depressed.

"The kid is finally gone. Liu Wal shook his head, and then introduced to everyone: "This little guy is the grandson of one of my uncles, he is more pestering, he recognizes things, and often does not hit the south wall and does not look back. ”

Everyone smiled in understanding.

The walnuts on the stall were not of good quality, and everyone was not interested in staying here, so they continued to set off for the antique shop, and at this time, Lao Niu also followed.

When Meng Zitao saw that he was in trouble, he asked, "Old Niu, what's the matter?"

Lao Niu replied: "I met the sixth child just now, and he intends to invite you to a meal, I don't know when you have time?"

"Yo, the sixth is making a fortune. Meng Zitao said with a smile.

Lao Niu said: "What kind of wealth did he make, it seems that he has something to discuss with you, but it shouldn't be a big deal, otherwise he will definitely come to you in person." ”

"What's the matter?"

"I don't know, this guy is mysterious and won't tell me anything. ”

Meng Zitao thought for a while: "That's okay, just tonight, I'll contact him later." ”

"Okay. ”

"By the way, what's going on with this stall that bets on green skins?"

"Have you heard about Qingfeng cold storage?"

"Qingfeng cold storage?" Meng Zitao recalled for a moment: "Is it the cold storage that had a liquid nitrogen leakage accident two months ago?"

"Yes, this person is the owner of the cold storage. ”

Liquid nitrogen is a liquid at a low temperature of -196°C, which is obtained from nitrogen that occupies more than 70% of the air composition. Inert, colorless, non-toxic, volatile, and has a very wide range of use. Liquid nitrogen is volatile at low temperature, so it is generally stored in a special container - liquid nitrogen tank.

According to the purity and use of liquid nitrogen, it is often divided into food-grade liquid nitrogen and industrial-grade liquid nitrogen. The application of food-grade liquid nitrogen is like liquid nitrogen ice cream and liquid nitrogen biscuits, and high-purity liquid nitrogen is also required for liquid nitrogen freezing and anesthesia in medicine. Other industries such as chemical, electronics, metallurgy, etc. have different requirements for the purity of liquid nitrogen.

Because of the low temperature of liquid nitrogen, skin exposure to liquid nitrogen can cause skin frostbite. If the nitrogen produced by vaporization at atmospheric pressure is excessive, the partial pressure of oxygen in the workplace will decrease, which will cause hypoxia.

Lao Niu said that the Qingfeng cold storage was because of the leakage of liquid nitrogen, which led to a serious accident of four deaths and one serious injury.

"Could it be that he didn't open cold storage and changed his career to the green walnut business?" Meng Zitao asked.

Lao Niu waved his hand: "Of course not, these green-skinned walnuts were actually his investment some time ago, and he wanted to make a profit, but now there is an accident, and his family has almost lost everything, and he can only sell these green-skinned walnuts." ”

"So that's what happened. ”

Lao Niu left immediately because of something, and Meng Zitao took everyone to his antique shop, and saw that Hu Yuanliang had already taken a calcite equipment. This equipment is relatively small, but a few kilograms of wool can still solve the problem.

"Boss Liu, just these four pieces of wool. Meng Zitao picked a few pieces of wool from the box.

Liu Wal was a little surprised by Meng Zitao's choice, he smiled and said, "Mr. Meng, can you say it if it's convenient, why didn't you choose this piece of wool?"

Yu Weigang was also a little strange about this, he was also optimistic about the piece of wool that Liu Wall said, but Meng Zitao just didn't choose it, what is the reason?

Meng Zitao smiled slightly: "I remember that there is a way to make fake materials, which is to polish the green glass-ceramic into a gravel-like layer and apply it on the surface, in order to disguise it as a high-grade jade stone that has been manually wiped, rough polish the surface, and then apply powder on the surface, so that it can cover those obvious traces of artificial friction, so that it feels like the original jade stone skin layer is too thick, which is the characteristic of the artificial rubbing skin." ”

Liu Wal frowned and said, "Mr. Meng, do you mean that this piece of wool is made using this method?"

Meng Zitao didn't care about Liu Wal's angry performance, he smiled and said, "I only know that this piece of wool doesn't feel cold when it touches my hand." ”
