Although Wang Feng is eager to try it now, he doesn't have a good goal yet, so he plans to go to the Internet to check the metals that are common and can be obtained by himself.

After thinking about what to do, Wang Feng came back to his senses. When I saw the empty plates and bowls on the table in front of me, I remembered that I hadn't cleaned up the dishes and chopsticks yet. Speaking of this empty plate and empty bowl, Wang Feng recalled the dishes he had made before, and felt that he had not eaten for a long time, how refreshing and enjoyable.

After cleaning up the dishes and chopsticks, Wang Feng looked at the time and was startled, it was almost six o'clock now, and he had been distracted for more than three hours.

Wang Feng shook his head and thought, "Looking for metals that can be recycled and are cost-effective, there is no hurry now." On this hot day, I stayed in the hospital for two more days, and I could get lice on my body if I didn't take a shower, so I still went to the Internet to check about metal after taking a shower. ”

So, Wang Feng took a change of clothes in the bedroom and went to the bathroom to take a shower.

In the process of taking a bath, Wang Feng found that his figure had improved, with eight-pack abs and vest line.

Wang Feng's muscles are not like the coaches in the gym, but his streamlined body shape makes people feel very explosive when they see it, which makes Wang Feng, who has not exercised much since graduation, surprised and delighted. Wang Feng thought to himself: "This is all the benefit of the system." Now that he has such a good figure, coupled with his brother's peerless appearance, who else in the world can resist his brother's strategy?"

Wang Feng quickly took a shower after a while, and threw his dirty clothes into the washing machine by the way. Then Wang Feng sat down at the computer desk in the bedroom and turned it on. Taking advantage of the boot time, Wang Feng went to the refrigerator and took out the iced watermelon, cut half of it and ate it, put the other half back in the refrigerator, and then went to the kitchen to wash a spoon and returned to the computer with the watermelon.

Wang Feng habitually logged in to the Penguin, looked at the news in each group, and chatted a few words by the way. Remembering that he hadn't done anything yet, Wang Feng hastily ended the chat, opened the website and checked the mineral metals.

............

Two days later, in the afternoon, Wang Feng sat on the sofa at home with a depressed face. In the past two days, Wang Feng searched the Internet for various metals and places to sell them, and he tried them one by one, but the results disappointed him. He ran to the hardware store, and even went back to the hospital to get a piece of titanium alloy for artificial bone, but these efforts were not of much use.

Common metals: titanium, tin, copper, aluminum, zinc, lead, steel, iron, only titanium, copper and iron can be recycled among these metals, but the cost performance is too low, such as ten points per ton of pig iron, it is better to exchange money for points directly.

The eight metal elements of precious metals: platinum (Pt), palladium (Pd), rhodium (Rh), iridium (Ir), osmium (Os), ruthenium (Ru), gold (Au), and silver (Ag), among which Wang Feng has only tried gold and silver, and the others have no access to specific information. The cost performance of gold and silver is relatively okay, and Wang Feng can make a little profit if he redeems points, but he will definitely not earn too much.

However, due to the low content of gold and silver in the earth's crust, it is difficult to explore, mine and refine, and the global reserves are not large.

In the entire history of thousands of years of civilization, the total amount of human beings dug up from this planet is all combined, about 1.43 million tons of silver, which is equivalent to 45.9 billion ounces, and at the peak of the 90s of the 20th century, the annual consumption of silver by the world's photographic industry is about 6000~6500t, or about 200 million ounces. At present, about 3,000 tons of silver are used in various electrical industries every year.

According to the U.S. Mint, from 1493 to 1954, at least one-third of the silver produced by humans has disappeared from the world – and since 1954, silver has disappeared even faster due to the massive consumption of industry!

In 1940, the world's reserves of gold were 1 billion ounces, and the reserves of silver were 10 billion ounces. But by 2009, the world's reserves of gold were 5 billion ounces, and the reserves of silver were 1 billion ounces.

World Mining Association official statistics of gold and silver world reserves table by year (100 million ounces)* 1 ton is equal to 32150.75 ounces 1 ounce is equal to 0.0311034768 kilograms.

This also limited Wang Feng's access to gold and silver, and this recovery function was calculated on a per-ton basis for these metals, so Wang Feng simply did not have access to that much gold and silver.

In addition, Wang Feng got these metals, and he recycled them into points, that is, he completely disappeared into Azure Star. The massive disappearance of these metals will certainly have a big impact, both for businesses, for finance, and for the planet itself.

Therefore, Wang Feng can recycle a small amount of metal, but he must not recycle a large amount. Disrupting the order or the environment, this is not what Wang Feng wants to see. It's better to switch to the restaurant industry.

Wang Feng sat on the sofa with a lot of thoughts, and suddenly thought, why did he prefer to turn the tip of the horns on the metal? The essence of jade is not comparable to those metals, and it can definitely be recycled! As soon as he thought of it, Wang Feng immediately put on his clothes, got up and went out, and went to the "Hua Yuxuan" in the city.

Twenty-five minutes later, Wang Feng arrived at the door of "Hua Yuxuan", which was worthy of being the first jade shop in the city.

After Wang Feng entered, he saw that there were many people inside, and a shopping guide with a good face said to him politely with a professional smile: "Hello, sir!

When Wang Feng heard this, he said, "Do you have any varieties of jade?" Wang Feng wanted to try every variety of jade.

The shopping guide gently introduced to Wang Feng that the jewelry of their "Hua Yuxuan" is placed according to the variety of jade, and except for the alias jade, other jade species are available here.

After that, Wang Feng politely thanked the shopping guide and said, "I haven't thought about what to buy, so I'll look around first, and then greet you when I see what I like." ”

The shopping guide replied politely and walked away.

After two days of exploration, Wang Feng knew that as long as he was within five meters, he could know whether the item could be recycled through the recycling function, and if he wanted to know the specific price of recycling, the item had to be in Wang Feng's hands or within one meter. If you want to recycle it directly, it must be within one meter of Wang Feng in the process and the item must not have the slightest resistance.

Two hours later, Wang Feng returned home satisfied, and he had already got the information he wanted.

As Wang Feng expected, jade can indeed be recycled, and the points given by the system are not expensive, and they are converted per kilogram.

However, the price of finished jade is higher, and it is not cost-effective to buy these. Wang Feng also asked the shopping guide, if you buy unprocessed jade, the price will be much cheaper. After all, the first thing to buy jade is the variety, and then look at the appearance and meaning of the finished product after carving, and there is also the appreciation of the handwriting of famous teachers. And these things that added value in the later stage did not mean anything to Wang Feng, after all, the system would not increase the price of the jade because it was carved by a famous artist, unless someone could give the jade other energy.
