    "Secondly, try to find walnuts from the same tree and branches. Generally, when a batch of walnuts is harvested, walnuts from the same tree are more likely to have similar shapes and textures. Some walnuts have even branches. Nuclear farmers usually keep the original branches when picking them.  , such a pair is more approachable in shape and size"

    Yu Xi was talking eloquently, but before he finished speaking, he was interrupted by Liu Woer next to him: "Okay, don't think that I don't know about betting on walnuts. I also know what you said, but  No matter how much you talk, it is just talk on paper without actual combat. In this way, I can give you a chance."

    As soon as he heard the word "opportunity", Yu Xi's eyes lit up a little, and he said quickly: "Brother Liu, just say it."

    Liu Woer said: "In this way, you can buy a pair of green leather and bet on it later. 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 Woer shook his head: "Impossible. I said I wouldn't sell it to you this time, so I won't, but I can bring you a similar piece next time. Of course, you don't have to agree."

    "I promise!" Yuxi agreed immediately. If he didn't agree at this time, there would be something wrong with his brain.

    Liu Woer smiled and said: "It's a good thing to have confidence, but if you can't succeed in gambling after a while, then you can go back to me honestly. In addition, you only have one chance. If you fail this time, you will automatically admit defeat."  ."

    "You can rest assured." Yuxi patted his chest. Although he had only bet on Qingpi a few times, the results of the few times he had done were very good, so he was very confident in himself.

    Since there was nothing else to do anyway, everyone squeezed into the crowd to enter the queue of selectors. Meng Zitao lowered his head and saw that the green skin here did not look fresh. In fact, this was a normal thing.

    Theoretically, the time for walnut trees to fall is generally from the summer heat to the white dew, which extends for one to a few days, usually in August and September of the Gregorian calendar. Of course, due to different geographical locations and different characteristics of each tree species, walnut trees fall from trees one after another.  There are mornings and evenings.

    But it¡¯s already mid-November, so the walnuts here must have been refrigerated so that they can remain as they are now.

    Meng Zitao couldn¡¯t help but shook his head secretly when he saw many people choosing green walnuts, because these people may not know much about betting on green walnuts and have overlooked some of the issues.

    Betting on green peel is actually like jadeite. It is difficult to judge the quality and size of the walnuts in the green peel simply by observing the appearance. Many freshly grown green peels are put directly on the stalls without peeling. One is twenty or thirty.  Making money is the same as betting on stones, it all depends on the buyer's vision and luck.

    Compared with jade stones, green walnuts are fruits, so they have the characteristics of fruits. For example, walnuts will shrink after being dropped from the tree. People who know about this generally know that the size of the walnut should be the largest in one month after it is dropped from the tree.  , it will shrink by about 1mm, but in addition, there is another risk that is more harmful to walnuts during this month, and not many people may know about it, and that is "cracking"!

    Because this period is the time when the dryness and humidity of the walnut cortex changes the most, the shrinkage process causes uneven density of the walnut cortex and different drying shrinkage in places with different thicknesses. Therefore, 98% of Wenwan walnuts crack.  within this period of time.

    You see that there are so many people betting on green walnuts every year, but how many pairs of people survive and become old walnuts?  It is not an exaggeration to say that it is "a drop in the bucket" or "a rare thing".

    From October to December every year, the drying and shrinkage period of walnuts has passed. When buying walnuts, you can almost see the direct size, and you can also observe the cracking.

    So it stands to reason that now is a good time to buy walnuts, but the crux of the problem is that these walnuts have been refrigerated, which will undoubtedly delay the drying and shrinking time. Therefore, if you buy the green-skinned walnuts here, you will also face the problem of drying and cracking.

    A cracked walnut is basically scrapped and cannot be played with at all.  But look at the crowd surrounding the green leather bets in front of you, how many of them understand that the walnuts are basically useless after they are bought?

    Of course, none of this has anything to do with Meng Zitao. If you want to bet on Qingpi, you should be prepared to lose all your money. Moreover, the price of a few tens of dollars is not expensive. In the end, it doesn't matter even if the bet fails.  .  Of course, if you choose the green-skinned walnuts that cost thousands of dollars a pair next to them, you will feel a little sad if the bet fails.

    Back to the topic, Meng Zitao looked to the side and found that Lao Niu was also there, and Lao Niu also saw him and nodded to him with a smile.

    Meng Zitao also smiled at him and motioned for him to continue picking green walnuts.?: "This little guy is the grandson of one of my great uncles. He is quite clingy. Once he knows what is going on, he will never look back until he hits the wall. If he is not sent away, he will do some things when he is trying to solve the problem.  The moth comes out."

    Everyone smiled and expressed understanding.

    The quality of the walnuts at the stall was not very good, and no one was interested in staying here. They continued to go to the antique store. At this time, Lao Niu also followed.

    Seeing that he looked troubled, Meng Zitao asked, "Old Niu, what's the matter?"

    Lao Niu replied: "I just met Lao Liu, and he wants to treat you to a meal. I wonder when you are free?"

    "Hey, the sixth one is getting rich." Meng Zitao said with a smile.

    Lao Niu said: "How did he get rich? It seems that he has something to discuss with you, but it shouldn't be a big deal, otherwise he would definitely come to you in person."

    "What's up?"

    "I don't know either. This guy is so mysterious that he won't reveal any information to me."

    Meng Zitao thought for a while: "Okay, let's do it tonight. I will contact him later."

    "OK."

    "By the way, what's going on with this betting stall?"

    "Have you heard about Qingfeng Cold Storage?"

    "Qingfeng Cold Storage?" Meng Zitao recalled for a moment: "Is it the same cold storage where the liquid nitrogen leakage occurred two months ago?"

    "Yes, this person is the boss of the cold storage."

    Liquid nitrogen is a low-temperature liquid of -196c, which is obtained from nitrogen that accounts for more than 70% of the air component.  Inert, colorless, non-toxic, easily volatile, and has a wide range of uses.  Liquid nitrogen is easily volatile at low temperatures, so it is generally stored in a special container - a liquid nitrogen tank.

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

    Because liquid nitrogen has a low temperature, skin contact with liquid nitrogen can cause frostbite on the skin.  If too much nitrogen is produced by vaporization under normal pressure, the partial pressure of oxygen in the workplace will drop, causing hypoxia.

    The Qingfeng cold storage that Lao Niu mentioned was due to a leak of liquid nitrogen, resulting in a serious accident in which four people died and one was seriously injured.

    "Could it be that he stopped opening a cold storage and switched to the green walnut business?" Meng Zitao asked.

    Lao Niu waved his hand: "Of course not. These green walnuts were actually an investment he made some time ago. He wanted to make a profit. Now that an accident has occurred and his family has almost lost all his money, he can only sell these green walnuts.  "

    ¡°So that¡¯s what happened.¡±

    Lao Niu left immediately because he had something to do. Meng Zitao took everyone to his antique shop and saw that Hu Yuanliang had already brought in a piece of stone dissolving equipment.  This equipment is relatively small, but it can still handle a few kilograms of wool.

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

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

    Yu Weigang was also a little strange about this. He was also optimistic about the piece of wool Liu Woer was talking about, but Meng Zitao just didn't choose it. What's the reason?

    Meng Zitao smiled slightly: "I remember there is a way to make fake materials, which is to grind green glass-ceramic material into a gravel shape and apply it on the surface. In order to disguise it as a high-grade jadeite stone that has been artificially rubbed, the surface is roughly polished.  , and then apply powder on the surface, which can cover up those obvious artificial friction marks, so that it feels like the original jadeite stone skin layer is too thick, which is the characteristic that appears after artificial skin rubbing. "

    Liu Woer frowned and said, "Mr. Meng, you mean to say that this piece of wool was made using this method?"

    Meng Zitao didn¡¯t pay attention to Liu Woer¡¯s angry expression. He smiled and said: ¡°I only know that this piece of wool does not feel cold when you touch it.¡± (Remember this website¡¯s website address: www.hlnovel.com
