"Old Wu, don't laugh at me! I don't study mining, nor do I study metallurgy, so it's normal to not know! So if I ask you what is DOTA, what is CS, what is WC3, you must not know, right? I asked Lao Wu with the name of the game, "Tell me quickly, what is the use of fire alchemy?" ”

"The so-called, real gold is not afraid of fire, and true grandsons are not afraid of tests!" Lao Wu pretended to be a professor and said to me seriously, "Gold sand is all grain by grain, and there are a lot of mercury and other residues in it, burning it into gold water with fire, on the one hand, it can be formed, on the other hand, it can remove other impurities, and the melting point of gold is relatively high, and mercury or something has become gas!" Know no! It's called junior high school physics! ”

"Got it, Mr. Wu!" I followed Lao Wu's "play" and continued to cooperate with him.

"Haha!" Lao Wu laughed as he took out a small bowl from the corner and said that the bowl was inaccurate, more like a small jar of ceramic crickets! Lao Wu poured the gold grains into the gold bucket and poured it into this small vat. Wei Ergou handed over the gold grains he had found last week, and Lao Wu poured them into this small pot together.

I was about to ask him what the little vat was called, when Wu took out a powdery object like flour from a plastic bag. Then he took the small bowl and placed it on top of the charcoal that was already burning on the edge of the kitchen, and he turned on a blower to blow it into the fire.

"Old Wu, what is that little bowl? You're trying to melt the gold, aren't you? "Won't that little bowl melt?" I saw Lao Wu stand up and wash his hands in the basin, and asked after him.

At this time, Wei Yiyun also stood over curiously to look at the small pot that was burning, and inside the small pot was the "gold nugget" of our trophies for more than a week.

"Melt? The melting point of that bowl is 3800 degrees, and this coke burns to 1500 degrees at most, how can it melt! I'll just say you didn't study physics! After washing his hands, Lao Wu teased me while taking the tea that Wei Ergou gave him.

"That little bowl is a molten gold crucible, which is specialized in smelting gold! By the way, Lao Wu, what kind of material is he? Wei Ergou sat next to me and said with a smile.

"Graphite crucible!" Lao Wu took a sip of tea, lit another cigarette, dragged it for a minute, looked at us, and then spit out a puff of smoke rings and said.

"Graphite? What is Graphite? "It's really the first time I've heard of this.

"You don't even know graphite! Xiaosheng, this chemistry class must be taught! Wei Yiyun stood next to the crucible and laughed at me, "Graphite chemical formula C, it's carbon!" Diamonds, that is, diamonds, are all carbon, they are allotropic forms! ”

"Oh, come to think of it, diamond is the hardest substance!" I scratched my head and looked at Wei Yiyun.

"Graphite, on the other hand, is the softest in nature! Ha ha! "I really don't have much impression of what Wei Yiyun said, I have been playing games for four years in college, and I have already returned my high school and junior high school to the teacher.

"That's right, this crucible is made of graphite! There is still a gap between the same college students! Lao Wu laughed at me next to him, "Xiaosheng, I'll give you another chance, tell me what is the melting point of gold?" ”

"Erh, 2000 degrees?" I casually guessed an answer that I don't remember at all.

"1064 degrees!" Wei Yiyun blurted out.

"Haha, Xiaosheng, you college student is not worthy of your name! If you look at Yiyun, you know that the knowledge level of Guangxi people is higher than that of you Shanghainese, haha! Lao Wu sat next to the hot pot and continued to laugh at me while watching the fire.

"I'm ashamed, I've disgraced the people of Shanghai! But Lao Wu, you Guangxi people are good at digging gold, you must know all the relevant knowledge, right, you take what you are doing better than what I am not good at, then I will definitely suffer, right? "I'm quite embarrassed, but I also thought of a way to reply to Lao Wu, I can't embarrass the Shanghainese.

"So what are you doing, let's see if we know?" Lao Wu asked me unrelentingly.

"For example, I visually observed that your Yin Hall was dark and the human middle collapsed, I pinched my fingers and counted, your old Wu aspect is a bit empty!" I used the symptoms that Erijia said to make a fool of Lao Wu.

Lao Wu was stunned by what I said, as if the secret in my heart had been told by me, and I didn't know what to say if I wanted to say it for a while.

"Huh? Which aspect is that? Lao Wu, are you a little empty? Zhu Yong also heard our conversation on the side, and as soon as he heard his old profession, he paid special attention to the question.

"Go, go,! Lao Zhu believes in you! Okay, okay, let's not talk about it, this gold has to be burned for an hour, look at the mud on my body, you have washed and changed your clothes first, and I will wash it too. "Lao Wu was hit by what I said, and he didn't want to continue the topic, so he found an excuse to go out to take a bath. The bath of the shed is very simple, the water is the water accumulated in the mud pit dug by the excavator next to it, put it in the bucket to precipitate it clearly, use the water of the upper part of the water directly to pour a big spoon on the body to rinse, the bath is on the side of the shed, it is directly enclosed with a color steel plate, the so-called bath is to wash it with water.

"Xiaosheng, you just said that Lao Wu is empty, how do you kid know? Don't say it, before the last time we came to Ghana together, we were in Shenzhen, I asked them to go to the foot washing city, and Lao Wu was done in a few minutes, hahahaha! Zhu Yong talked about the past when they came to Ghana.

"I deduced it based on the reaction of the Divine Fruit!" I smiled, Wei Ergou and Zhu Yong both looked at me, "Really, why are you looking at me like this, what I said is true." ”

"Xiaosheng, you kid really thinks of yourself as a shaman!" Zhu Yong said with a smile at me.

"Lao Zhu, you laugh at me again, don't say it, we're all hungry! What a good thing to eat today! I touched my stomach and asked Zhu Yong.

"It's all right, I'll start eating when Lao Wu comes back from taking a bath! Today I went to the town, and I happened to come across Pearl, who helped me go to the slaughterhouse and buy a lot of pork knuckles, pork livers, and pork head meat! Did you know? Black people don't like to eat these things, I basically picked them up for nothing, I bought 20 pork feet, two pieces of pork liver, a piece of pork head, guess how much I spent? 5 Sadie! 20 RMB! Zhu Yong said that the spit splashed, as if I drove into the city today to pick up a big bargain.

"That's quite cheap, it's all the credit of my pearls Okay, I asked her to wait for you, I called her to tell her that you would go grocery shopping, so I waited for you on the way through, and I also asked her to help buy some pig's trotters, just a few days ago, Lao Zhu, the soybeans you bought were stewed together!" Wei Yiyun talked about his arrangement.

"Okay, okay, your pearl! But then again, this girl is really good, diligent and sensible and smart, although she looks black, she actually has a good figure and a very warped buttocks! Zhu Yong said with a hippie smile, "I said, Yiyun, you asked your pearl to help a few of our brothers also show up, right?" ”

"Who made a bet at the beginning that they would never touch a black girl, why did it change in just a few days?" Wei Yiyun remembered Zhu Yong's bet and asked him.

"Man! There is a demand! Zhu Yong also smiled, "Really, you tell your pearl to find a local girlfriend for us, we can rent a house in Dongkua and house the local family group, right?" ”

"Lao Zhu, your abacus is not bad, specially set up a heaven and earth in the town, right? Go and go, bring the dishes first, Lao Wu is here! Wei Ergou impatiently beckoned Zhu Yong to serve the food.
