It looks like a mathematician pondering over a mathematical formula.
Seeing Meng Yan's appearance, several of the waiters quietly approached Zheng Jinguo and asked in a low voice.
"Boss Zheng, Mr. Meng seems to be very interested in this purple-black rough stone. Do you want us to be a favor?"
After being reminded like this by his subordinate, Zheng Jinguo reacted.
Yes, this rough stone has been cut into pieces anyway. Meng Yan is so interested in it, why not just give it to him as a personal favor.
"I will discuss with Mr. Meng later. You two should put this rough stone in a sack first."
After Zheng Jinguo made up his mind, he gave these instructions to his men.
Meng Yan was still pacing back and forth minding his own business when he suddenly saw several of Zheng Jinguo's men lifting stones from the stone cutting machine and stuffing them into sacks, and hurriedly stepped forward to stop them.
"Hey! What are you doing? Boss Zheng and I are still looking at this rough stone."
Several guys stopped tying up the sacks in their hands. Zheng Jinguo saw this and came up to meet him, smiling at Meng Yan.
"Mr. Meng, this rough stone collapsed three years ago. No matter what Mr. Meng thinks, I don't think there is much hope."
"Since Mr. Meng is so interested in this rough stone, I am going to give it to you directly, Mr. Meng. You can take it back and do whatever you want with it."
"So it's because of this!" Meng Yan looked at something not far away, slapped his forehead, and said in sudden realization.
Zheng Jinguo was immediately confused: "Mr. Meng, what on earth are you talking about?"
Meng Yan asked Zheng Jinguo, pointing to the sack where the two men carried the purple-black rough stone.
"Boss Zheng, what do you think this is?"
Zheng Jinguo followed Meng Yan's hand and found several large red characters clearly written on the sack containing the rough stones.
"Industrial nitrites."
"This is the sack used to contain nitrite. Mr. Meng, why do you ask for this?" Zheng Jinguo asked doubtfully.
"What is the nitrite used for in the jade field?" Meng Yan asked rhetorically.
As if he thought he understood what Meng Yan meant, Zheng Jinguo smiled and waved his hand.
"Mr. Meng, I know what you are thinking, but this situation is completely impossible."
"Although nitrite is corrosive, it comes from the outside in, and the area washed by it is as bright as new, and ordinary impurities cannot penetrate it at all."
"On the contrary, it can be said that if a rough stone is washed with a solution mixed with nitrite, then the light will not only not be blurry like this, but will illuminate more transparently."
Although most of this kind of work is done by stone gambling shops, in some places, it is also done in order to process the rough stones and make them look better.
This kind of work is called grinding stone in the jargon of the industry. It uses physical methods to polish and polish the sandy surface of raw stones to make them look smoother and tighter and increase their appearance. This method is generally used
It is used on cheap kilogram materials.
Of course, there are also some people with ulterior motives who will polish the rough stones that are already selling well.
Because the grinding stone not only increases the price of kilograms of materials that generally cannot be sold at high prices, but also has a greater effect. After the rough stone is dug out from the entrance of the field, the original small lines of moss, pine flowers, etc.
The clues were erased.
There are many masters who relied on the tiny clues on these rough stones to have better eyesight than others and eventually made a fortune. If these details are erased, the test of the buyer's eyesight will be even higher.
Hearing Zheng Jinguo's words, Meng Yan smiled slightly and shook his head.
"Mr. Zheng must have misunderstood me."
After saying that, Meng Yan sniffed the air in the factory.
"Mr. Zheng, could you please try your best to breathe in some air in the factory like me? Tell me what it smells like?"
Although Zheng Jinguo was a little confused, he still sniffed hard according to Meng Yan's words. When several people on the side saw this appearance, they couldn't help but imitate it.
"It doesn't smell like anything?" Zheng Jinguo asked.
"It's just like the air in all our factories in Myanmar. It's not as fresh as in the mountains. It's also mixed with some particles and acid..."
When Zheng Jinguo said this, he suddenly closed his mouth, as if he realized something, his eyes widened, and he looked at Meng Yan in disbelief.
"Mr. Meng, what do you mean?!"
Meng Yan smiled and nodded: "Mr. Zheng, you finally noticed."
It is almost eight or nine o'clock in the evening. Myanmar's subtropical climate close to the equator causes the temperature to drop suddenly at night. Coupled with their dense jungle, the humidity will be very obvious.
Meng Yan stretched out his finger and touched the metal levers that could be seen everywhere in the nearby factory, and put his finger in front of everyone.
Water droplets visible to the naked eye.
"The climate here in Myanmar is close to the subtropical zone. The hot temperatures during the day will immediately drop at night. The extremely strong temperature difference between day and night causes such tiny water droplets to form on any object that can be attached."
"But if it's just like this, then there are many places in our Xia Kingdom that have a similar climate. This is not enough to oxidize the sand inside this purple-black rough stone." Meng Yan continued to explain.
"Mr. Zheng just said that your man used this rough stone as a stepping stone for the factory. And Mr. Zheng, your factory is being built in the lowest place in this area, and the humidity can be said to be the heaviest."
"In addition, the entrance to the rough stone field is right outside. Once the rough stone is dug out, it will be sent to the factory for grinding and processing with nitrite solution. Over time, this smell will be mixed in the air."
"In other words, some of the nitrite solution evaporated into the air."
At this point, everyone suddenly realized.
Indeed, if it is ordinary water vapor, it will not be able to oxidize the sand surface of the original stone within two years. But the problem is that this water trace also contains corrosive nitrite solution, which is another matter.
.
"Mr. Meng, in that case, this purple-black rough stone..." Zheng Jinguo asked hesitantly.
Meng Yan nodded: "As Mr. Zheng said, there is still hope."
Upon hearing this, Zheng Jinguo immediately slammed the table, pointed at his two waiters and said loudly.
"Hurry up and take out this rough stone again!"
Although none of the waiters had gone to school, after hearing Meng Yan's long and uninterrupted speech, Jue Li had a deep admiration for him. After hearing Zheng Jinguo's words, he naturally did not dare to slack off and quickly put the sack in the sack.
The newly installed rough stones were lifted out and placed on the stone cutting machine.
