。 "Boom, boom..."

In the vicinity of Dawu County, more than 100 kilometers north of Wuhan, a group of workers are using bulldozers and other important facilities to dig an artificial lake out of a plain...

"It's a big project..."

Looking at the tens of thousands of workers who were working there, a farmer in the distance sighed, joking about the Three Kingdoms - the latest chapter of Haruko's book.

"Yes, I heard that the president has already shed a lot of money for this project..."

On the other hand, Yan Guang himself was also surrounded by a large number of people, looking at the scene in front of him.

"How's it going?"

Looking at the construction scene in front of him, Yan Guang asked lightly.

"We have already completed one-tenth of the progress, and if we continue to maintain this efficiency, I believe it will be completed by the end of this year or early next year..."

Standing beside Yan Guang, the magistrate of Dawu County replied with a smile.

"Hmm..."

Yan Guang nodded.

"Keep up this progress, if you lack funds, you can ask me, and after the lake is completed, you must also ensure the environment and safety of this lake..."

"Don't worry, I understand this..."

But when he said this with a smile, the magistrate of Dawu County also muttered in his heart.

Artificial lakes are reservoirs, hydraulic engineering structures used to hold water and regulate water flow, and can be used for irrigation, power generation and fish farming.

In some places, artificial lakes exist in the form of a landscape, architecture, etc.

Unlike natural lakes, "Artificial Lakes" embodies the wisdom of human beings in using and transforming nature, and other book lovers are reading: The latest chapter of Immortal Monk and Strange Child. Reservoirs have emerged and developed with the emergence and development of human beings to solve floods and store water for later use. More than 4,000 years ago, the people of ancient Egypt and Mesopotamia began to build the world's first reservoirs to prevent flooding and to irrigate the land. The Chinese built the Shaobi irrigation project in the sixth century BC, and the project is still in use today. According to statistics, the total storage capacity of reservoirs in the world reaches 55 trillion cubic meters. The water surface area is more than 350,000 square kilometers.

Generally speaking, artificial lakes are mainly used as reservoirs, and there may be more fish farming or other purposes, but they are usually smaller in size.

However, this time, Yan Guang sprinkled a huge amount of money near Dawu County. More than 400 kilometers of area were bought, almost the entire area of Honghu Lake, the seventh largest freshwater lake in China.

And on such a large area, the construction is ready to dig out a large artificial lake...

However, it is surprising that such a large area of artificial lake is not a reservoir used for water storage or power generation. It's for the sake of fish farming ...

Ahem, maybe it shouldn't be called fish farming, but farming, no, it should be freshwater dolphins...

Baiji...

Baiji dolphin (scientific name: ipotesvexillifer), also known as baiji whale, baiji dolphin, baiji, baiji, baiqi, baiji, jiangma, qingji, yangzi finless porpoise and yangtze porpoise, is a freshwater cetacean baiji dolphinidae, only produced in the middle and lower basin of the Yangtze River in ♀ China, is the only unique species in the baiji dolphin family, to the 20th century due to various reasons its population declined, in 2002 it is estimated that there are less than 50.

It is one of the least abundant of the four remaining freshwater dolphins in the world and is a national first-class protected wild animal in China. In 1996, it was listed as one of the 12 most endangered species by the International Union for Conservation of Nature (now known as the International Union for Conservation of Nature, abbreviated), ‖and was also listed on the IUCN Red List of Threatened Species, the Convention on International Trade in Endangered Species (Appendix I), and the National Endangered Species Act of the United States. After a failed six-week field survey in November-December 2006, the species is thought to be probably extinct, and even if there are any individuals still alive, it is difficult to maintain and sustain the species, as other book lovers are watching: Legion of Wealth. …,

The baiji dolphin was first recorded in the Qin and Han dynasties' dictionary "Erya", and the animal was named "Zhou" ♀ because there was little knowledge of cetaceans and other water mammals at that time, so it was mistakenly classified as a fish. The word "fish" is used next to the word "fish" in the creation of the word. The fishermen along the Yangtze River call it "". It is estimated that there were as many as 5,000 in China, and they were known as the goddess of the Yangtze River and the "mermaid of the Yangtze River".

In 1914, the young American adventurer Hoy collected a specimen of the baiji dolphin in the Dongting Lake area of China, but he was not familiar with the species at the time. So he took the specimen and asked the local fishermen, and it turned out that according to the local Hunan and Hubei accents, he wrote "peihi" ("white flag") ♀ on the specimen and brought it back to the United States. S. Miller's interest. Based on the specimen of the baiji dolphin, Miller has made a comprehensive and detailed study of morphology, anatomy, and the position of its bones and teeth. Miller further compared the skeleton with sub-puffer fish specimens collected in the Brazilian Amazon Basin.

1918 year. Miller published a summary of his research in the Smith Institute's journal series in a research paper titled "A New Species of Freshwater Dolphin from China." It was confirmed that the baiji dolphin was a unique new species of animal, and the Latin scientific name was established: "ipotesvexillifer". Miller also named the baiji dolphin "hinese riverdolphin" (literally translated as "Chinese finless porpoise").

In this era, the baiji dolphin has not yet reached the point of extinction, so although the existence of the baiji dolphin has attracted the attention of some scientists, not many people have expressed concern about their survival.

However, this does not include Yan Guang...

According to the survey results before the war, that is, in 1938, there were probably more than 1,000 baiji dolphins in the Yangtze River, which is indeed much more than the number in later generations, but in the early years, that is, when the Yangtze River was not as prosperous as it is now, it was estimated that there were more than 2,000 baiji dolphins in the Yangtze River in 1913.

In just 30 years, there has been such a big change...

If the Yangtze River continues to prosper with China, I am afraid that in the 21st century, the Baiji dolphin will be completely extinct in the Yangtze River, the latest chapter of the beautiful novel: The Tide of the Iron Blooded Man.

It was in this situation that Yan Guang began to think about plans to protect the Baiji porpoise—————— and many other plans were launched at the same time. For example, pandas, South China tigers, etc., but the most important thing at the moment is the white dolphin...

The number of baiji dolphins is decreasing year by year, mainly due to its poor reproductive ability and more human activities in the Yangtze River Basin. Most of the cetacean aquatic species to which the baiji dolphin belongs survived in the saltwater after migrating tens of thousands of years ago, and the population of cetacean freshwater dolphins living in freshwater basins across the world is small, and the remaining five species of freshwater dolphins are all endangered. Furthermore. According to genetic studies, the genetic diversity of baiji dolphins is low, which also exacerbates the rate of extinction. Scientists have proposed ex situ conservation for this reason.

The area of the lake has been reduced due to the reclamation of land around the lake, the construction of dams has blocked the migration of fish between rivers and lakes, and the water pollution of the Yangtze River has increased. In the Yangtze River, there is a serious shortage of fish eaten by baiji dolphins, which destroys the living space of baiji dolphins and poses a serious threat to the survival of their population.

Fishermen in the Yangtze River basin also led to the death of the baiji dolphin. The baiji dolphin is large, and when it enters the fishing net set up by fishermen to catch small fish in the river, it will constantly struggle, making the net messy, and it is difficult to rescue it from the net in time. There are also many fishermen who use illegal fishing methods in order to increase their catch. Occasionally, the baiji dolphin will unexpectedly fall into the net and die, which has a direct impact on the baiji dolphin group.

Overly busy water transportation on the Yangtze River, severe river water pollution, and the construction of a large number of water conservancy projects all threaten the living environment of the baiji dolphin, especially the noise pollution caused by various human activities. It has a great impact on the baiji dolphins, which rely on sonar systems for identification and positioning, and many baiji dolphins are buried in the propellers of ships. The Yangtze River is one of the most important waterways in China, with an average annual volume of ships and thousands of ships equipped with propellers, which can easily cause accidental casualties caused by Baiji dolphins colliding with propellers. The baiji dolphin is small and has a pale gray complexion. It is not obvious, and it is extremely difficult to distinguish in the dirty water of the Yangtze River, which has a perspective of less than one meter. In the construction of large-scale water conservancy projects or during the removal of waterways to bomb rocks, baiji dolphins have also been found crushed to death by stones. …,

It is precisely because of this that Yan Guang decided to build a giant artificial lake comparable to Honghu Lake in Dawu County, which is 100 miles away from the Yangtze River, ∞. Naturally, he is the richest man in the world...

Anyway, he's the richest man's money, and now it's too much to spend, and other book friends are reading: The Witch - The Seven Deadly Sins txt download.

And he doesn't have any children, and he only has a three- or four-figure secretary around him, so it's better to spend the money where it should be...

So far, through various methods, the staff in the Yangtze River have captured more than 10 baiji dolphins. Now they are all kept in small conservation bases in various places, and when the artificial lake is completed, these baiji dolphins can be sent here.

Of course, the opposition to this is not small, after all, the construction of such a large artificial lake is also a great damage to the surrounding ecological environment, but Yan Guang has another calculation in his heart...

Why did people in later generations eat puffed pork while protecting pandas and tigers? It is because these latter poultry are not as precious as pandas and tigers, and no matter how much they eat, it will not have much impact on the existence of these groups.

The same is true now, the construction of such a large artificial lake will indeed have an impact on the local ecology, but it will only affect ordinary organisms. Although it may be a bit cruel to say this, they are indeed not as precious as the white dolphin.

In later generations, there was a baiji dolphin named Zhenzhen, who was caught in 1986, and was originally going to marry another baiji dolphin named Qiqi, who had been caught for a long time, but in 1988 he died of illness.

It wasn't until 2006 that Chen Peixun, the first person to study white-sided dolphins, reluctantly revealed one of the possible causes of Zhenzhen's death: the awning on the west side of the pond was of poor quality, and iron filings, wood chips and other debris would fall into the pond on windy days. Since there were no other ponds to divert the white-sided dolphin, it was never repaired' after Jane's death, and 700 grams of iron filings and stones were found in its stomach.

Therefore, a good environment is indeed very important...

"What is the purpose of crossing? Isn't it just to make up for regrets, rather than regretting it one day in the future, it's better to let it go now..."

As for the opposition at home? It's nothing to Yan Guang now...

"Speed up the progress, it must be completed before next year..."

After saying this to the commander-in-chief of the construction team, he waved his hand to the workers who were under construction, and in the cheers of the workers, Yan Guang left Dawu County and was reborn in the candy box.

There are still many things waiting for Yan Guang to solve. He couldn't afford to stay here for long.

"But such a large lake, it should be enough for the Baiji dolphin to survive, right? But it doesn't matter, if it's not enough, it would be nice to continue to expand, anyway, there will be many projects to move mountains and reclaim the sea for the sake of political achievements in the future, what is it for me..."

Thinking so, the light left Dawu County.

————————————————————

While Yan Guang was still there inspecting the artificial lake where Yang Heng would be raised in the future, on the Nanyang Islands, fierce battles were still going on.

Due to the overwhelming superiority of the Wehrmacht in overall strength, the Japanese army was losing ground almost every day. Even so, however, IDF casualties are increasing daily.

And it's no wonder. After all, the Japanese army is not a second-rate country, and it can be regarded as a first-class power. In particular, in terms of crude steel production, although Japan did not reach the level of France in 39 until 42, it is quite remarkable.

What's more, the battlefield at this time is still on the jungle-covered Nanyang Islands.

If it is a plain duel, it will indeed be easy to clean up Japan, after all, Japan does not have much armor at all. The so-called chariot under the Wehrmacht or the German army can only be described as low-level. …,

That kind of armored force, it may be okay to bully African countries, but against the Wehrmacht...

Hehe...

However, in the jungle, although the strength of the Wehrmacht is still stronger than that of the Japanese army, there are many times when the terrain also needs to be considered. And it's obvious. The Japanese were more familiar with the terrain than the Wehrmacht.

As a result, while the Japanese army continued to drive away, the casualties of the Wehrmacht also increased dramatically.

In the battle of Malaysia alone, the Defence Force paid more than 300,000 casualties—————— attention, it was casualties...

And if you want to occupy the entire South Sea Islands, I am afraid that this number will have to quadruple...

In particular, the Japanese, who were hiding in the jungle, were unable to confront the Wehrmacht because of their confronting the enemy. They even set up many traps in the jungle instead of facing the Wehrmacht head-on. Very often, the Wehrmacht, who went into the jungle clearance, paid a terrible price before even finding out where the opponent was...

That is, in this case. The commanders, who were in charge of directing the operation, began to think of some special ideas...

"Buzz Buzz Buzz..."

In the sky above a jungle, a -3 bomber was flying under the escort of several D-20s. In fact, this kind of escort is completely meaningless, because in the past series of battles, the Defense Air Force has almost beaten the planes of the Japanese Army Airlines. Until now. Unless it's a large-scale campaign, it's just a general bombing mission, and the Army Aviation will not be dispatched at all.

"It's here..."

Look at the jungle below. The navigator said lightly to the pilot.

The jungle below was a place where Japanese soldiers were hiding.

The Japanese troops hiding here have repeatedly repelled the Wehrmacht's clean-up missions, for which the Wehrmacht has paid considerable casualties ♀, and with the stimulation of some other places, the Wehrmacht has begun to think of some extreme measures...

"Let's start fighting..."

Saying that, the crew members, including the pilot, put on a mask for themselves, and the costume they were wearing was not the usual flight suit, but a protective suit ...

"Ten, nine, eight, seven, six..."

With a faint countdown, a bomb fell from the bomber's magazine and eventually exploded over the jungle...

"Boom, Flame of Youth!"

With a bang, a yellowish gas spread out in the area where the bomb exploded...

At this time, several Japanese personnel under the air explosion area of the aerial bomb were still looking up there...

"Hmm..."

While the Japanese were still wondering what was going on, a Japanese soldier suddenly clutched his throat and fell to the ground in pain, and soon several other soldiers also fell to the ground, and in other parts of the jungle, similar things kept happening...

The soldiers who fell to the ground were almost all curled up in a ball, like shrimp...

And their skin is also...

"I don't know what's going to happen down there..."

After dropping the bomb, the bombardier smiled bitterly.

"I'm sure you won't want to know..."

Hearing the words of the bombardier, the doctor who specially participated in the flight said lightly.

The doctor can be said to have quite a good understanding of the poison gas used this time. In order to take adequate precautions, doctors have also seen some photos of chemical weapons after use...

VX gas, that's the weapon used this time...

VX Poison is a more toxic nerve agent than sarin, one of the deadliest chemical weapons, and the latest chapter in the good-looking novel: Dreaming of Cold Snap. It is also a colorless and odorless, oily liquid once it comes into contact with oxygen. It will turn into gas. Industrial products are yellowish, yellow or brown, and a small amount of mercaptan will be decomposed during storage, so it has a foul smell, mainly because of the liquid to cause poison to the ground and objects, which can be transmitted through the air or water source. Almost imperceptible. Human skin contact with it or inhalation can cause poisoning, and headache and nausea are the main symptoms of infection with this poisonous gas. VX gas can cause central nervous system disorders, respiratory arrest, and eventually death. …,

Among the various chemical agents, according to the length of their killing time, they are divided into temporary agents and persistentagents. After the persistent agent is applied, it is in the form of droplets or fine powders, causing poisoning on the ground and poisoning by contact with personnel. The effective killing time is more than 60min, and the poison used is mostly liquid poison with high boiling point and non-volatile such as mustard agent and VX. In order to hinder, delay or contain the opponent's military operations, the fine powdery agent settles on the ground after being applied, and flies again when people or vehicles pass through or when the wind speed is high, so it can cause poisoning on the ground and air for a long time.

VX is a transliteration, also known as Vickers gas, which is a poison first discovered by the British in 1952. Later, the Americans selected VX as the focus of the development of chemical warfare agents, and the scientific name of VX agent is S-(2-diisopropylaminoethyl-methylthiophosphonate), which is probably the longest name among the poisonants.

VX is mainly loaded in shells, bombs, etc. It is used by the explosion dispersion method, and can also be sprayed by aircraft, and the VX poison agent infects the ground and the surface of the object with its droplets; It poisons the air with its vapours and aerosols. Protection against VX agents is the same as protection against other nerve agents, and full-body protective equipment should be used, i.e., gas masks, anti-poison, anti-gas gloves, anti-gas boot covers, etc., and the first aid of poisoned patients can be treated with Atopine drugs. Disinfectants such as hypochlorite and sodium dichlorotrimeric isocyanate can be used for its disinfection.

VX is typically a persistent agent with a killing effect lasting from a few hours to a few days and nights. VX agents are more toxic for a longer period of time than other nerve agents. The toxicity is strong, the lethal dose is 10 mg, a small drop of VX liquid drops on the skin, if not disinfected and treated in time, it can cause death, other book friends are watching: one step fairy demon txt download. v Chemical munitions are mainly used for delayed chemical attacks, hindering the enemy's mobility, preventing and restricting the opponent's use of favorable terrain and equipment, and weakening its combat capability.

The Communist government has never used chemical weapons, but this does not mean that the Communist government has not researched ♀ this area like a nuclear bomb, although it has been used a few times in total, and it is very likely that it will never be useful in the future, but no major country has stopped researching this aspect...

The same goes for the national government...

Because of the outstanding effect of chemical weapons in World War I, the Communist government never stopped researching chemical weapons, but never used them.

After all, at that time, the Nationalist government, like Russia, was a thorn in the side of Western countries, and China at that time was not as powerful as it is now, so it was natural to do less things that were easy to say.

But now...

In order to effectively reduce casualties, it was also necessary to use...

Anyway, the opponent is Japan, which has used chemical weapons on the battlefield, and the Kokusha government has not used anything.

Moreover, the chemical level in Japan is very low, and Nomenkan poured bacteria into the river, but because he was afraid of leaking secrets, he kept it secret from his troops, and as a result, many people were poisoned by drinking river water. On the contrary, the Soviet army does not drink river water directly, they have special logistics water pipes and water wheels...

And against opponents in the jungle, chemical weapons are indeed very effective weapons, as for incendiary bombs or something...

Although it was equally effective, the Nationalist government's attack on the South Sea Islands was not for the sake of a blank slate. You must know that the South Seas are full of jungles, and if they really burn, it will not be easy to control...

Moreover, a blank field is useless to the national government, and the puppet government can only become a burden after it is established.

So, chemical weapons are probably the best option...
