Chapter 0405 is clear at a glance

Mangroves, sand dates, poplar willows, and 10,000 each.

Looking at such a prize, Gu Yu couldn't afford to vomit. In the past, when he drew lotteries, he didn't draw similar prizes, such as the dead wood aphrodisiac elixir, which was used to treat trees on the verge of withering, and the effect was magical. There are also refreshing tea, physical chocolate, etc., which seem to be inconspicuous little things, but they are all things that are very helpful to him, and the scientific and technological content is not low.

But he really couldn't see how the three kinds of trees of mangroves, sand dates, and poplar willows could help him, did he let him open a nursery, and go to sell trees for fun? How much money could he sell? How many dollars a plant? Or a dozen yuan, dozens of yuan?

Gu Yu rubbed his temples with a little headache, he was really about to be defeated by this lottery system. He took a deep breath and looked at the reputation he still had left, and found that there were more than two billion, which was not less. He is not willing to let this lottery pass like this, he will go to BX country in a few days, if he can't find other investment projects, he can only put the treasure on the sea, land and air amphibious individual combat vehicle project, then there may be a risk that he will return empty-handed in BX country, which is definitely quite unfavorable for him to expand his influence in BX country.

Without thinking too much, Gu Yu decided to continue the lottery, he still didn't believe it, and the lottery system could still allow him to draw trees all the time. Gritting his teeth, Gu Yu bought a full 10,000 lottery chances again, and the 500 million prestige value was gone in a blink of an eye, he bet all the lottery chances at one time, and then started the lottery machine.

After a few moments, the lottery machine's wheels slowly stopped, and there was no sound. Gu Yu smiled bitterly and shook his head, is it time for the empty prize again?

He spent 500 million reputation points again to buy 10,000 lottery chances, and then bet them all on, and immediately activated the lottery machine again.

Just when Gu Yu didn't have any expectations for this lottery, the roller stopped turning, but the system prompt sounded.

"Congratulations to the player for winning the jackpot - E+ level prize seawater resistant mangrove cultivation manual, it is detected that the player has used 10,000 times the bet, so this manual can be upgraded to 10,000 E+ level and below plant cultivation manual. Will the players withdraw their prizes?"

It seems that the lottery system is dry with plants such as mangroves, what else can Gu Yu do? It is better to have a prize than nothing, so he chose to extract.

The system beep sounded again.

"The Plant Cultivation Manual has been copied to the system interface, and players can go to view it on their own. ”

Gu Yu didn't rush to check, he didn't think that plant cultivation would be his investment project in BX country, he still felt that he had to continue the lottery. So, he bought 10,000 investment opportunities again and bet them all.

Then this time Gu Yu didn't draw anything, not only this time, but in the next few draws, Gu Yu still didn't draw anything. Seeing that the prestige value has decreased by 500 million and 500 million, in the end, there are only more than 100 million left, and it is impossible to think of another 10,000-fold E+ level lottery.

Gu Yu stopped, he looked at the last remaining prestige value, and sighed, these prestige points are still kept in case of emergency, not to mention the rest, the non-staple food area of the system store will be updated again soon, if you don't leave some prestige points, it is impossible to even empty the non-staple food area.

It seems that it is not easy to find other investment projects through the lottery system, Gu Yu can only press this matter down first, and prepare to wait until he arrives in BX country to consider this matter, if it really doesn't work, he can also divide the projects that have now settled in China, the United States or JND to BX countries, and get a branch or processing plant or something, isn't this what many multinational companies do?

Gu Yu calmed down and came to the system store, although he didn't like the several prizes drawn this time, but this was also worth it for him to spend five billion prestige, even if he didn't like it, he had to understand it and see if they were easy to plant, if so, he would go back to China and find a place to plant them all, which would be regarded as his contribution to the greening of China.

Gu Yu first checked the sea-resistant mangrove, he absentmindedly clicked on the manual of this plant, first looked at it casually, and then his eyes widened, and he looked at the manual with a look of disbelief.

Mangroves, Gu Yu is known, there are mangroves growing in the coastal areas of some provinces and cities in the south of China, they are not afraid of seawater, they can directly take root in the seawater to grow, it is a kind of tree species that looks amazing to people in the north. It is precisely because Gu Yu knows this that he thinks that the so-called E+ grade plant sea-resistant mangrove that he drew is a dispensable prize, and if he needs mangroves, he can go to the south of the country to buy them, as much as he wants.

However, when Gu Yu saw the E+ grade tree species sea-resistant mangrove, he realized that his idea was still too underestimating the lottery system. This seawater-tolerant mangrove has one thing in common with ordinary mangroves, that is, they can grow in seawater, but it would be wrong to think that seawater-resistant mangroves only have such one characteristic.

In addition to being able to grow in seawater, the E+ grade species of seawater-resistant mangrove has several characteristics that ordinary mangroves do not have, that is, fast growth, high timber yield, and high developable value. Moreover, the requirements for ambient temperature are much smaller than those of ordinary mangroves.

According to the instructions, if the seawater-resistant mangrove saplings are planted on the beach or the coast with relatively shallow seawater, then within five years, the seawater-resistant mangrove can grow to a height of more than ten meters, and the thickness of the adult is surrounded by humans, while ordinary mangroves cannot grow to this extent anyway, and even if they can grow to this extent, their growth time needs to be measured for decades.

Even if you plant seawater-tolerant mangroves in the north where the temperature is low, they can grow, and their growth cycle is longer than in the south, but it will not take more than eight years to grow.

When the trunk grows to this extent, then the sea-resistant mangrove can naturally be used as wood, and its material may not be suitable for high-end furniture, but it is absolutely no problem to make ordinary furniture and boards. In addition, it is very suitable to use seawater-resistant mangrove trees to make wood pulp and finally make paper.

This is only the economic value of the seawater-resistant mangrove, which is its smallest value, and the greatest value of the seawater-resistant mangrove is actually in environmental protection. You need to know how much seawater and how much carbon dioxide it needs to absorb in the process from a small sapling to a tall tree in just five to eight years.

According to the instructions, a seawater-resistant mangrove will absorb about one ton of carbon dioxide and no less than ten tons of seawater in five to eight years.

That is to say, if there are 10,000 seawater-resistant mangroves, then during this time, they will be able to absorb and solidify about 10,000 tons of carbon dioxide, and no less than 100,000 tons of seawater will be absorbed. If you magnify it tenfold, it will become 100,000 tons of carbon dioxide and millions of tons of seawater.

Among the most criticized environmental issues today are rising levels of carbon dioxide in the atmosphere and rising sea levels. Planting seawater-tolerant mangroves will not solve these two problems completely, but it can greatly alleviate them.

Especially for the absorption of carbon dioxide, the seawater-resistant mangrove can be called an artifact. If a large number of seawater-tolerant mangroves are planted along the coast of China, the number of planted mangroves may need to be measured in tens or even billions. If measured at 100 million plants, calculated according to the longest growth cycle of eight years, it is equivalent to reducing the annual carbon dioxide emissions of more than 10 million tons in China.

Today, the world's annual carbon dioxide emissions are about 41 billion tons, which means that these sea-resistant mangroves can absorb about 4,000th of them. That's a pretty impressive number.

If we imagine that seawater-tolerant mangroves are planted on a large scale on coastlines around the world, it is believed that human beings, who are plagued by increasing carbon dioxide concentrations, may not be as anxious as they are now.

Artifact, this is definitely an artifact.

Gu Yu's eyes lit up, he was still more concerned about environmental protection issues, otherwise, he would not be willing to spend tens of billions of dollars to invest in various environmental protection undertakings. If seawater-tolerant mangroves can be promoted, not only can they reap considerable economic and environmental benefits, but also definitely a huge amount of prestige value.

This award was not wrong, the dissatisfaction in Gu Yu's heart disappeared in an instant, not to mention that there were several other prizes, even if there were none, this alone would not be a loss of the five billion prestige points he spent.

Gu Yu temporarily put aside the E+ grade tree species seawater-resistant mangrove, and looked at the second tree species he extracted, that is, the salt-alkali tolerant tree species S. samphifera, he carefully read the instructions of this tree species from beginning to end, and found that this kind of salt-alkali tolerant sand date is strengthened on the basis of the existing saline-alkali plant S. spp., and its environmental protection value and economic value are also there, but the environmental protection value is much worse than that of the seawater-resistant mangrove.

The value of saline-alkali tolerant sand dates is mainly reflected in the economic value, they can grow in saline-alkali land, and the fruits of sand dates are nutritious, can make various snacks, and can also make wine, and the nutritional value of the wine is also extremely high.

Salinity-tolerant dates do not grow to exaggerated heights, but they can grow to the height of peach trees, which is much taller than ordinary dates.

Subsequently, Gu Yu checked the hardy poplar willow, and after reading the manual, Gu Yu also had a considerable understanding of this E+ grade tree species. Although the environmental value of drought-tolerant poplar is not as good as that of seawater-tolerant mangroves, its environmental value is not weak at all.

The drought-tolerant poplar is not very fast, and it is more drought-tolerant than the ordinary poplar, its roots are deeper, and the ability to store water and resist sunlight is stronger, which makes it thrive in a harsh environment where it is more drought than ordinary poplar. This thing is obviously very suitable for growing in desert areas, and it is an artifact for controlling and fixing sand.

Not only in China, but also in the world, desertification is a rather head-scratching problem, if we can plant drought-tolerant poplar willow in the desert, then how many deserts will become Saijiangnan? This is definitely another weapon that can earn prestige points in a big way.

Gu Yu realized the value of three tree species, he found that only 10,000 trees for each tree species was too little, he hurriedly checked how much prestige value was needed to buy these three tree species, and when he saw it, he shook his head again and again.

These tree species are not expensive, a plant only needs 5,000 prestige points, which does not seem to be much, but don't forget, this thing has to be planted in patches to be useful, so that it can be calculated, then it has to be hundreds of thousands, millions or even tens of millions, hundreds of millions of prestige points to fill in, in order to be able to buy a sufficient number of E+ grade tree species to plant.

Gu Yu only has more than 100 million reputation points left, and if they are all used to buy sea-resistant mangroves, it is only more than 20,000 more, which is not much.

Gu Yu sighed, he had already understood a truth, that is, the prestige value is never enough to spend. It seems that in the future, I haven't figured out a way to earn more prestige.

Gu Yu came out of the system store, and just when he wanted to leave the system space, he suddenly thought that he had also drawn a prize, which was the Ten Thousand Species Cultivation Handbook. His heart moved, and he hurriedly stood in front of the holographic light brain of the system and opened the manual of ten thousand plant cultivation.

Gu Yu found the names of seawater-tolerant mangroves, salt-alkali tolerant dates and drought-tolerant poplar willows on it, and after opening them respectively, he was pleasantly surprised to find that it introduced the whole process of how to use ordinary mangroves, sand dates and poplar willows to cultivate into seawater-tolerant mangroves, salt-alkali tolerant dates and drought-tolerant poplars.

Not only that, Gu Yu also found a greater number of plants in this manual, including tree species, as many as 10,000 species. Seeds like the rice and noodles that Gu Yu bought in the non-staple food section of the system store can be found in this 10,000 kinds of plant cultivation manual. In addition, how to grow artificially grown ginseng to be as medicinal as wild ginseng, and how to make tomatoes grow as big as eggplants while retaining the sandy and sweet characteristics of tomatoes, etc., are all recorded in detail in this handbook of plant cultivation.

Gu Yu casually looked at the cultivation methods of several plants, and realized that the value of this book is much higher than the value of seawater-resistant mangroves, after all, the number of seawater-resistant mangrove saplings is limited, and when they run out, they have to use prestige to buy, and with the methods provided in this manual for the cultivation of ten thousand plants, he only needs to spend money to be able to get a steady stream of seawater-resistant mangroves, as well as other nine thousand nine hundred and ninety-nine kinds of magical plants, the value of the two is naturally clear at a glance.
