This question is Xiao Peng's answer to Yang Meng: "About 30,000 people die of rabies in China every year. And 97% of the dead are in rural areas, of which 99.99% have not been injected with rabies vaccine, and a small number of vaccine deaths, just like James said, before the rabies vaccine is injected, the rabies virus has spread along the nerves and invaded the central nervous system, which also has a lot to do with the patient's personal immunity. But do you know how many vaccines China sells every year?"

Yang Meng replied honestly: "How could I know this." ”

Xiao Peng gave the data: "Fifteen million! At present, China is the world's largest market for rabies vaccine consumption, and in this environment, dozens of domestic and foreign vaccine companies are very competitive in the market, and some vaccine companies deliberately spend money to exaggerate the incubation period and incidence of rabies in the human body, so that more people can consume rabies vaccines." Do you think, that thing is cheap and costs forty or fifty-one injections, expensive four or five hundred and one injections, how much room for profit here? Especially now that Chinese are not bad for money, as long as they are bitten by dogs, wound treatment, vaccination, and immunoglobulin injections must come to a complete set, then spend money. And the gap between the rich and the poor in China is still very large, so on the issue of rabies, it is generally 'rural people get sick, urban people get vaccinated', and the cost of vaccines is often one or two thousand, which is also a big burden for those with low incomes, isn't it?"

"In Australia, about a million people are bitten every year, but only about 10,000 people are actually vaccinated," James said. And almost all of them are given after observation using the '10-day observation method'. There are only three kinds of people who rush to get vaccinated after being bitten: rich people, children, and Chinese。。。。。。 ”

Xiao Peng pointed out his middle finger at James: "We Chinese are both rich and expensive! What do you want us to do? This is called self-protection! This is called being prepared for danger in times of peace! If it were not for us Chinese who had this good habit, where would we find adrenaline to save you!"

James raised his hands, "Okay, can't I surrender?" By the way, we know you're going to dig Opal today, come over and see if you can help." ”

Xiao Peng pointed to the mound behind him: "You came here after we have all finished our work, you are really sincere。。。。。 ”

Steve, who couldn't speak, looked at the mound behind the two of them: "I'll it, you dug it up all morning?"

"Of course. Why don't you go down and have a look?" asked Xiao Peng.

"Let's go, Steve, look at the mines our Chinese friends have dug up, maybe there's something good. Xiao Peng directly started the generator, and lights appeared in the mine. Steve and James put on hard hats and went down to the mine, but as soon as they entered the mine, they heard Steve shouting, "God, you're digging in the wrong direction!"

Xiao Peng walked over, and James said: "It is undeniable that the mine you dug is very good, no matter what the reinforcement work is, it is very professional, but digging black opal, it is really not that the deeper you dig, the more material you have, you must find the sandstone layer, and the black opal only exists in the sandstone layer." If you dig deep, it's not black Opal, it's useless. ”

Xiao Peng didn't explain, but walked in front: "Let's go, follow me down and have a look." After speaking, he took the lead and walked into the newly dug mine, and before he had walked nearly ten meters, James stopped and stroked the mine wall: "Xiao, you see, it is this black sandstone layer, this is the parent rock where Black Opal grows, and Black Opal exists in this layer." ”

Xiao Peng smiled: "Follow me and continue to walk down." ”

James and the two didn't know why, and followed Xiao Peng all the way to the end, but they were dumbfounded: "Why is there another sandstone belt?

Xiao Peng said with a smile: "Foolish people have stupid blessings, yesterday it rained and a hole rushed out next to the mine mouth, we dug along this excavation, and after digging to the end, we found this new channel, this mine turned out to be a double-layer sandstone layer." I found a new sandstone layer. ”

Steve looked shocked: "How is this possible?"

James thought for a long time, and clapped his hands vigorously: "I understand what's going on!"

"James, why is this happening?" Steve was puzzled.

James explained, with a look of shock, "The terrain in our half of the mine is much higher than that of Parrot Valley. The sandstone layer on the surface is pseudosandstone, and the bottom layer is the sandstone layer on the same level as the 'Parrot Valley' sandstone layer! I'll just say, why can they dig the same sandstone layer and Black Opal, but we don't have it here! It turns out that we dug the wrong one from the beginning!"

Steve thought for a moment: "Xiao, you are such a lucky man! Judging from the output of Parrot Valley, you will not lose money on this mine." ”

"What is this called? Good people have good rewards, haha, how do you say this? God always blesses good people, doesn't he?" Xiao Peng looked stunned: "Look, this is what we dug when we dug a hole." ”

After speaking, Xiao Peng took out a lambskin bag from his pocket and handed it to James, who was stunned: "This is 。。。。。。 ”

"Won't you just open it and see it?" Xiao Peng said.

James opened the bag and sat on the spot with Steve: "You dug this up?" Inside were six pieces of Black Opal, one of which was won by Buck.

Xiao Peng nodded: "I saw it when I was mining." ”

James smiled, "Shaw, you're such a lucky guy!"

"HAT THE FACK!" STEVE suddenly screamed, picking up one of the oval opals and looking at the light of the mine wall.

James frowned: "That's a fossil Opal, why are you so shocked?"

Steve said, "Hurry up, come out with me, I can't see clearly under this mine!"

The group was confused by Steve and followed them back to the ground.

In Australia, Opalized shellfish fossils are common, and there is even an Opalized plesiosaur fossil called the Loch Ness Monster, which is an entire Opal dinosaur fossil.

This 'Loch Ness Monster' fossil was found in 1968 in the ditch on the edge of the Great Salt Pans of Lake Torrens in Andamka, Australia, more than 50% of the bones have been Opalized, which means that it is both a plesiosaur fossil and an Opalized gemstone, in Australia, Opalized shellfish fossils are more common, but Opalized plesiosaur fossils are very difficult to find, and this complete 'Loch Ness Monster' Opal has been protected by Australian Heritage Law. It belongs to a national treasure.

The piece of Opal that Steve was holding in his hand was an obvious clam fossil Opal, and although this black Opal was more precious than ordinary black Opal, it was not completely invisible. So after Xiao Peng dug it out, he put it directly in the sheepskin bag and didn't take it out, and he didn't look at it carefully.

When a few people were on the ground, James took the Opal from Steve's hand and observed it in his hand, and took it and looked at it for the first time: "Falker." He also burst into foul language.

Steve looked anxious next to him: "How's the clarity, are there cracks, are there any variegation?" James shook his head.

Steve was on the sidelines: "Choke to death, choke to death!"

Xiao Peng looked at the two of them puzzled: "Isn't this just a blue Opal? Why are you so excited?" That Opal Xiao Peng also observed, the individual can have half of the Opal that Buck lost to himself, it is a translucent Opal, only blue one color, he did his homework when he came, like this, the price of a black Opal with only a blue color is not high, that is, a hundred dollars to five hundred dollars a carat, you know, the price of the top black Opal is tens of thousands of dollars a carat! No matter how good the best direct is not a carat, the overall price is directly the whole. For Black Opal, the more colors you change, the more valuable it is, and the more colors you have, you can sell it for more than $2,000 a carat.

Because there are many types of Opal color changing colors, the more vivid the higher the price, up to seven color changing colors, according to the color value, from high to low for red, orange, yellow, blue, purple, green, light blue, of which red has the highest value, which does not look like an exciting Opal.

"It's a blue Opal, God, you struck this pretending man to death with lightning bolts. Steve exaggerated. James nodded in agreement.

Xiao Peng looked at the two of them puzzled, and James explained: "Look at your Opal, although there is only one color, but if you look carefully, the core is black, and then dark blue, dark blue, little by little changes to the light blue on the surface. And there is no abruptness at the color junction, everything is natural! This kind of color change is very superb, such an Opal can be sold for at least more than 10,000 carats, and you can have about 20 carats, and you can calculate how much it is worth yourself. ”

Xiao Peng whistled: "It seems to be developed." Dig a few more dollars and you'll be back. ”

James smiled: "I'm still talking about the price of carats, if you really like this piece of Opal, you will already pay back the money you paid for this mine! Your luck is really good, you found such a vein! Now the price of Gravel Opal has also gone up, and it is not bad to dig more of that thing." ”

Gravelback Opal is a symbiosis of Black Opal, above the black Opal epigenetic parent rock, Gravelback Opal is epiphytic in dark brown sandstone, once the price of Gravel Opal was only one-fifth of that of Black Opal, but with the decline in the production of high-quality black Opal, the price of this Gravelback Opal has also risen a lot.

"I've borrowed your good words. Xiao Peng nodded in response.

The price of this black opal is very different, and like the white opal, you can't find two exactly the same black opals in the world, so it is impossible to have two black opals of the same value.

There are many factors that can be used to measure the value of black opal: color change, brightness, color contrast, clarity, cracks, other packaging variegation, weight, and so on. The cheapest black opal is 100 Australian dollars a carat, but the best black opal can reach tens of thousands of dollars a carat, digging black opal is the real luck work: first of all, it depends on whether you have the luck to dig it, and secondly, it depends on what quality you dig up. If you're lucky, a top-notch black Opal can make a fortune directly, just like the 'Halley's Comet' Black Opal unearthed in Lightning Ridge, which is a rough stone, but the price has already exceeded 10 million US dollars!

Yang Meng said: "Let's eat, continue to dig after dinner? After tossing all morning, I starved to death." ”

"Okay, what are we going to eat?" Xiao Peng asked.

As soon as Xiaopeng finished asking, Xiao Isaiah ran over with the puppy in his arms: "Mr. Xiao, we have already prepared!"

Xiao Peng Yile, this is from home with food, and it's not bad to try this Australian food.

I only saw little Isaiah running to the carriage and opening the baffle, Xiao Peng saw that there were two large plastic buckets inside.

"Mr. Xiao, I caught two large buckets of crayfish, is this enough to eat?" Little Isaiah's face was happy, and suddenly he had a question: "Hey, Mr. Xiao, why do you have such a bad face? Are you okay?"

"Uh, I'm fine, I'm just a little sore。。。。。 ”
