The second technology is heavy metal pollution control and recovery technology, the emergence of this technology is a big coincidence, this technology, is an American accidentally discovered, that is when he was traveling in the primeval forest of the Great Xing'an Mountains in China, accidentally slipped his foot, fell into a valley.

The American was startled and immediately sent out a distress signal, and while he was waiting, he found that in the valley he had fallen into a strange tree had grown, the bark of which looked like metal, and the fruit on top of the tree was also shining, like a legendary cash cow.

And the American also took off the fruit on it, tried to bite it, sure enough, the fruit of this tree is simply an iron ball, this American is the first time to see a tree that grows a metal fruit tree, and after waiting for a day, the search and rescue team from Huaxia came and rescued the American.

The search and rescue team also noticed the tree, and dug up the tree and took it out, and after that, Huaxia began to study the tree, but accidentally, the American also hid a fruit on his body, and the search and rescue groups didn't care at that time, the fruit was brought back to his country by the American, and handed over to some scientific research institutions in the United States for research.

At that time, the technology of the United States was still much ahead of China, so it didn't take long for them to discover the secret of this tree, and found that the root system of this tree was abnormally developed, and it could absorb heavy metal ions in soil and water for growth, and the fruit produced was a natural alloy, which could be used for industrial production after a little separation.

The United States was also the first to use this technology to eliminate heavy metal pollution and recycle metal resources, and sold this technology to other countries at a high price, so that the United States earned a lot of foreign exchange, after all, after this technology was put into use. Many streets and alleys in the United States may have to plant this kind of tree, and it will be too difficult to keep this technology secret.

People only need to pick a fruit on the tree or something, and bring it back to be able to study it, so the United States has been a good person once, and Huaxia naturally did not spend money on this technology, after all, the United States asking for a price is not low, especially for Huaxia, they have opened a price of 10 billion US dollars.

After another week, Huaxia Fang finally cracked the secret of this magical tree. And put it into use, however, because of the loss of the opportunity, so this tree only let the heavy metal pollution in China be controlled, and the price of metal has also dropped significantly. However, it has not been able to obtain as much foreign exchange as the United States.

After all, the United States sold the technology of that tree to more than a hundred countries around the world. And according to the national strength of those countries. The sale price ranges from one billion to ten billion dollars, which is indeed a big profit, which can be said to be a million profits, of course, now that this technology is in the hands of Yan Feng, it is impossible for the United States to get so many benefits again.

And China doesn't need to be like the United States. After all, it's only 2014, not 2055. Nowadays, science and technology in various countries are making rapid progress.

More than 40 years later, the technology of heredity and genes in the relevant countries has made qualitative progress, so even if that magical iron tree has added various genetic codes and gene locks, it can still be cracked and made to reproduce, but now, the technology of various countries has not yet reached that level.

Therefore, Huaxia can rely on the sale of processed non-reproducible gold-absorbing tree saplings to earn a lot of extra money, of course, this technology, Yan Feng is ready to let the Xinlong Group take over, he here, can get a steady stream of technology, he is ready to develop the Xinlong Group into the world's largest enterprise, when the time comes, the capital will be continuous, and his own city air conditioning also has the possibility of being put into use.

And the next one, is a new type of sand control technology more than 100 years later, now the world, especially in China, the land desertification is becoming more and more serious, and every sandstorm is causing serious losses, and the best way to prevent sand is to plant trees, but after desertification, it is almost impossible to plant any plants.

Even if it could, it was very difficult, and more than a hundred years later, this technology completely solved the desertification of the land, and after this technology was put into use, in just two years, all deserts around the world were wiped out, including the Sahara Desert, the Taklamakan Desert and other giant deserts, all of which were wiped out.

The eradication of the desert is a fusion of two organisms, these two organisms, one is cyanobacteria, as a prokaryotic organism, the structure of cyanobacteria is very simple, generally in the sea, and cyanobacteria are extremely vigorous, and often prone to explosive proliferation, thus causing red tides.

After implanting a gene in cactus into cyanobacteria, cyanobacteria also have the ability to survive on the desert, and then, artificially create an environment that can make cyanobacteria multiply explosively, and then a large area of desert becomes a blue patch, and it only takes a few times for the desertified land to be fixed by cyanobacteria and turn back to the original healthy soil.

Of course, it is not so simple to extract the genetic abilities of these two organisms and form a new gene, otherwise, it will not be more than a hundred years later, this kind of creature will not appear, of course, for Yan Feng, who has mastered this technology in advance, as long as he has a biological laboratory that is currently relatively advanced, Yan Feng can synthesize this kind of biology.

And when the time comes, it will be sold to various countries in the world where desertification is more serious, presumably in a year or two, people want to see the desert, I am afraid it will not be easy, and the desert will become eternal history.

The last has always been the desalination technology nearly a hundred years later, this technology, in Yanfeng's view, is one of the four technologies that play a bigger role, water, is the source of life, but also the necessary conditions for human survival, but the water pollution is serious, water resources are getting less and less, 70% of the world's area is water.

If this technology is announced, the amount of water available to human beings will increase by more than 100 times, after all, the world's freshwater resources account for only 2 percent of the weight of water resources, and seawater accounts for 98 percent. (To be continued......)
