A corner of the "tenth power", Vientiane laboratory, waste-to-energy power plant, biometallurgical plant......

After calculating this series of projects, the dozens of small goals that Lin Han had just earned were about to bottom out again in a blink of an eye.

It's right to come back after the daughter is gone, but the premise is to earn it.

So after leaving Dongguang Province, he went to Nanhai Province non-stop to take over the task of invasive species management in Nanhai Province.

As the smallest province in China, Nanhai Province has less than 40,000 square kilometers, and with the full biological coverage capacity, it is more than enough to sweep twice.

After being swept away by the "anti-green buff" with full biological privileges, the invasive plant is undoubtedly dead.

But what made Lin Han feel a little tricky was that the Brazilian turtle, which was the most difficult for him, was actually the main force among the invasive animals in Nanhai Province.

This thing is hard and long, and it is inconvenient to collect, which is quite troublesome.

It's just that there are a lot of these things in Nanhai Province, and if they don't clean it up, it may affect the mission goal of eliminating 30% of the invasive animals.

"Gaia, can the biological authority allow the Brazilian turtle to run into the sea by itself?" Lin Han asked in his consciousness.

Brazilian turtles belong to freshwater animals, and freshwater animals and marine creatures, once they enter each other's territory, the drastic change in osmotic pressure, can quickly cause their death.

When marine animals reach freshwater, they end up being "strutted to death" by water, and when they reach seawater, they end up dying of dehydration.

The South China Sea Island is small, has a well-developed water system, and is surrounded by the sea, so it shouldn't take too long to get the Brazilian turtle to swim into the sea on its own.

Gaia was silent for a moment before saying, "This ...... Actually, I don't know. ”

Lin Han was stunned: "What do you mean?"

Gaia explains: "The evolutionary direction of living things is to better maintain their own survival. Therefore, if you control a specific creature to die, it is equivalent to violating the fundamental wish of life, and the effect will definitely be discounted. ”

"How much discount will be made, this is a case-by-case analysis. Organisms that are completely inintelligent, such as microorganisms and plants, certainly do not have such a problem. And if it's an ape, if you let it jump off a cliff directly, it probably won't be able to jump. ”

Generally speaking, the higher the creature, the more afraid of death.

The silverback gorilla, the strongest of the primates, is not without a fight with the tiger and lion in terms of physical hardware level alone.

But the reality is that the silverback gorilla has almost never won against the lion and tiger.

The reason for this, in addition to the combat power of the lion tiger itself, the gorilla's fear of death and weak fighting spirit cannot be ignored.

Lin Han said: "In other words, when the Brazilian turtle feels threatened by its life, some of them may flee?"

"Yes. However, what you said is indeed a feasible solution, once a small freshwater animal touches the seawater, the onset of dehydration symptoms is very fast. ”

Lin Han nodded: "Eliminate as much as you can, anyway, the area of Nanhai Province is not large, and you don't need to run much." ”

The area of Nanhai Province is only slightly larger than the coverage capacity of full biological rights, and he can cover the whole province by driving a little on the highway in the central region alone.

That night, wild Brazilian tortoises from all over Nanhai Province came into action, rushing from their hiding places to the nearest river waters......

Due to their rapid movement in the water, and the small size of Nanhai Province but the well-developed water system, these wild Brazilian tortoises quickly converge on several designated large rivers once they set out.

All of these designated rivers lead directly to the sea, and wild Brazilian tortoises can quickly rush to the sea as long as they go down the river.

However, not long after coming into contact with the seawater, the body of the Brazilian turtle began to show symptoms of dehydration, and its physiological state was chaotic.

Under the threat of death, a small group of Brazilian tortoises struggled to escape the sea out of a strong desire to survive.

Some of these "elite Brazilian tortoises" managed to escape the sea before they died, and survived after a period of recuperation.

Although some escaped from the sea for a while, they survived for a while due to heavy dehydration, but finally failed to escape the catastrophe.

Some failed to escape and were buried in the sea with the mainstream Brazilian tortoise.

Overnight, the people of Nanhai Province were shocked to find that there were countless more Brazilian tortoise carcasses near the surrounding coast, some of which had washed up on the shore, and some of which were floating in the sea on their backs.

Of course, some sank into the water and were used by some sea creatures to fill their stomachs.

Related news reports poured in, and a large number of photos went viral on the Internet. The news that Vientiane swept the Brazilian tortoise naturally aroused unanimous praise from people.

After a rough count, it was estimated that more than 90% of the wild Brazilian turtles in the entire South Sea Province have been wiped out, and the clean-up work in Vientiane has once again achieved remarkable results.

The remaining less than 10% of the Brazilian turtles survived, but they were all eunuch turtles that had permanently lost their reproductive capacity, as if they were no longer in the climate.

Most of the carcasses of Brazilian turtles around the coast were collected, sterilized and inactivated by high-temperature cooking, and then transported as organic waste.

During this time, there was also a small episode.

Probably that a third-tier Internet celebrity publicly made a statement to condemn Vientiane for hurting the little turtle, which is a great sin and a human being in vain.

Then someone listed the evidence for the first time, indicating that the Brazilian turtle is an ecological killer invasive animal, and while criticizing it fiercely, it also led the whole people to condemn it.

This incident almost set off a frenzy on the Internet, and the hot search remained high.

After Lin Han learned a little, he felt a little strange inexplicably, and only after inquiring did he know that it turned out that Liu Yufeng had made a big news by directing and acting by himself through the newly established Vientiane Media.

turned an ordinary third-tier Internet celebrity into a super negative Internet celebrity, and at the same time, it also made the person who took the lead in condemnation popular, and also invisibly brushed Vientiane with a wave of prestige.

The depth of the routine made Lin Han embarrassed for a while.

……

After the Brazilian tortoise was treated, the task of controlling invasive species in Nanhai Province was basically completed, and a total of more than 400 million yuan in clean-up fees from all parties was also received one after another.

Just as Lin Han was about to leave Nanhai Province, Secretary Zhang, Secretary of the Municipal Party Committee of Yangkou City, the capital of Nanhai Province, personally called him to greet him.

This made him a little surprised, after all, he was the secretary of the municipal party committee of the provincial capital, a member of the standing committee of the provincial party committee, and a deputy provincial boss who greeted him personally, and he definitely didn't talk nonsense.

"Huanghuali?"

On the phone, Secretary Zhang said: "That's right, it's the world-famous Huanghuali of the South China Sea." ”

Huanghuali, the scientific name is fragrant yellow sandalwood, originated in Nanhai Province, is a precious material for hardwood furniture in the Ming and Qing dynasties.

It is highly regarded for its yellow color, fine material, soft texture and aroma.

All kinds of excellent wood characteristics, as well as the scarce quantity, make the price of Huanghuali has always been high, the price of each ton of wood is as high as millions of yuan, and when it is fried in the sky, it can even reach tens of millions.

In the era of information isolation and unmanaged, some farmers often cut down wild huanghuali and take it back for their own use.

Later, some people noticed this phenomenon and bought rosewood in the countryside and sold it at a high price to make a huge profit.

As rosewood became more and more famous and its price became higher and higher, the number of people who stole it naturally increased, and a large number of wild trees suffered from the catastrophe.

Now the wild Huanghuali is already a national protected plant.

Secretary Zhang sighed: "Huanghuali can be said to be a business card of Nanhai Province, but you know a little bit about the current situation...... In the South China Sea, which is famous for its huanghuali, there are actually not many huanghuali with actual value, and the wild ones are almost extinct. ”

Lin Han thought for a moment: "Then what are you looking for me for?"

"Of course, I also know about the large-scale greening of Ayla in Vientiane, and I heard that you can promote the growth of plants, so I came to ask. ”

After a pause, Secretary Zhang continued: "I want to ask, is your technique also effective for Huanghuali?"

Lin Han said: "We can indeed promote plant growth, but the effect is mainly reflected in the early stage, after the plant body matures, the increase is not particularly significant. ”

Hearing the news, Secretary Zhang was not only not discouraged, but a little overjoyed: "Is it really effective?"

"Huanghuali grows slowly, and if it doesn't take a hundred years, it can't be used at all. As long as the growth of hundreds of years can be shortened by 20%, it will be able to reduce the watchfulness of a generation!"

The same goes for the growth of trees.

Ordinary trees, that is, the level of "ten-year trees", can be grown in as little as seven or eight years, and as many as one or two decades.

However, if you want to make a top-quality wood like huanghuali and small-leaved red sandalwood, it will take hundreds of years, and one or two decades will be useless.

The Huanghuali products on the market are basically bracelets, mainly because there are too few large pieces of wood, and the corners are only enough to make small objects such as bracelets.

Lin Han thought for a while and said, "According to the previous data, it is estimated that the maturity time of ordinary trees can be shortened by at least half. For huanghuali, if you only reduce the growth time by 20%, it is still no problem. ”

He is also very concerned about the effect of the green buff.

In order to test the specific effect, Lin Han deliberately bought a forest farm and counted the growth rate of the trees in it through controlled experiments.

After calculation, it is found that with the blessing of the green buff, the growth rate of trees shows a trend similar to that of a decreasing exponential function.

Although it varies depending on the tree, in general, the time to grow the tree can be reduced by about half.

"Cheng ...... The time to maturity has been shortened by half!" Secretary Zhang was so shocked when he heard the words that he stammered a little.

He thought it would be nice to be able to shorten it by 20 percent. Cut it in half, and the effect is simply incredible.

"Well, there are no side effects......"

Lin Han said with a smile: "It is absolutely green and pollution-free, except for the growth rings, there will be no other special places for trees." ”

Secretary Zhang was silent for a while: "Then I'll say it directly...... In the province of Nanhai Province, there are several nature reserves where some wild huanghuali grows. In addition to this, there are some businesses that have planted some in their respective tree farms. Of course, most of them are small trees, and large trees are rare. ”

"Therefore, the province would like to ask your company to carry out a maintenance on these small trees to speed up their growth, so that this business card of Nanhai Province can live up to its name. ”

"Of course that's fine, I can say yes. After all, it is also about protecting endangered plants. Lin Han said dryly, "The total area of those reserves and forest farms, how many square kilometers is it?"

"Square kilometers?"

Secretary Zhang was a little strange, but he still thought for a while and said: "If it is square kilometers, the reserve is only a few tens of square kilometers." The forest farms of several companies should be about the same size combined, but the planting density will be much larger. ”

After a pause, he added, "In terms of expenses, your company ......"

Lin Han smiled: "Since it is a feature of the South China Sea, a national protected plant, and we will not charge money for that part of the nature reserve." ”

Dozens of square kilometers, with the rarity of wild huanghuali, it is estimated that even if you can find a few thousand, even if it is good, you will not make much money by charging.

"As for the fees for the company's forest farms, I'll talk to their bosses. ”

……

Led by the staff of the Forestry Bureau, Lin Han went to a nearby nature reserve and was able to catch a glimpse of the legendary Shenmu Huanghuali.

"This is Huanghuali?"

He looked up and down the small tree in front of him for a moment, and asked in some surprise.

The tree in front of him was indeed too thin in terms of physique, more than one person tall, and his arms were thick.

Lin Han was very sure that he could pull the tree out of the soil with his hands.

Standing next to him was a young bespectacled girl wearing a hat, who worked in the local forestry bureau, and she nodded when she heard the words and said, "Don't look small about this huanghuali, it has been growing for almost ten years." ”

Decade!

After ten years of wind and rain, what finally grew into this thin one was just this thin one.

Lin Han carefully observed for a while, and gradually found that although this huanghuali looked thin compared with ordinary trees, it gave people a feeling of being quite extraordinary, and the leaves were all verdant, as if they had a bit of jade color, showing a strong vitality.

He looked at a few other small trees nearby and asked, "In this reserve, how many huanghuali trees are there, all of them are so big?"

The glasses girl stretched out her hand and pointed into the distance: "There are more over there, and there are about 600 wild huanghuali trees in the entire reserve, which are basically so big." ”

"The youngest looks no bigger than grass, and the thickest one is no thicker than a thigh. ”

She hesitated and asked, "Mr. Lin, can you really make these trees grow faster?"

Lin Han gently pinched a leaf of Huanghuali and said with a smile, "Of course you can." ”

"But for Huanghuali, slow growth is not the main threat, stealing and chopping is. If the supervision is not in place, even if these trees can grow overnight, they will still end up cheapening those who steal them. ”
