The rise of nanometers

At the Vienna International Airport in Austria, Brian received a blow as soon as he got off the plane. Under the escort of his family employees, he returned to his shelter base.

As the global situation has changed dramatically in recent years, many people with foresight have prepared shelters in advance.

Brian's father, Brian Sr., invested 82 million dollars to build a shelter with a high level of protection in his small town.

Brian, who was brought back to the shelter, showed a complicated smile when he saw his long-separated parents, sister, brother-in-law, and family.

"Welcome back, my boy!" Old Brian patted him on the shoulder.

Brian shook his head in distress: "Why is this happening? It's a mess outside now, it's just terrible."

His mother hugged him and comforted him: "Son, don't worry, everything will be fine."

At this moment, a piece of news was broadcast on the TV in the shelter. It was a real-time report from a BBC reporter in New York:

"Viewers! I am Frankie, the BBC correspondent in New York. Now I will tell you about the follow-up situation of the Yellowstone volcano eruption...

Cities in central and northeastern North America have been affected by the first wave of volcanic ash. The death toll in various places continues to rise. It is expected that the volcanic ash cloud will reach Xizhou in the next 15 to 18 hours. Please..."

Cough cough cough…

The BBC reporter's face turned red and he coughed. Apparently he had also inhaled a lot of toxic gas and volcanic ash.

in the report screen.

The overwhelming black snow, the gloomy sky, the panicked people, and the streets in a mess.

Brian's inner uneasiness became more intense.

On the other side, the Federation, which had been prepared for a long time, was not too chaotic. Even in Southeast Asia, where the quality of the people was not good, there were no large-scale riots.

There was not much of a problem on the Federation's side, but Xizhou, which bore the brunt, suffered a brutal blow 15 hours later.

In the snowstorm, the original white and flawless snowflakes turned into gray and black poisonous snow, and a large number of wild animals were destroyed in batches.

The rich are hiding in nuclear war-level shelters, while ordinary people can only hope for their own good. Those who are aware of prevention have already purchased gas masks and emergency food.

As for those who rush to the mall to buy something last minute, they can only gamble their luck.

All large and small shopping malls and stores in the Xizhou Alliance were sold out by frightened people in less than five hours.

When the black snow fell, those who failed to escape in time had their respiratory tracts directly damaged.

There are also some "smart" people who don't believe in the eruption of the Yellowstone volcano and still act indifferently.

Or those happy boys/girls who take "harmless stimulants" and are also high all night long.

These people became the first creatures to be eliminated by the volcanic ash.

Weak and ignorant, yet extremely arrogant.

Are these people not dead? Who dies?

the other side.

Sure enough, 27 hours later, weather monitoring ships in the Caspian Sea and Persian Gulf detected that a lot of snowfall contained volcanic ash.

Huang Xiuyuan, who spent the winter in Lingnan, also participated in federal emergency meetings through virtual meetings.

At this time, on the borders of various parts of the federation, especially the border areas in the northern hemisphere, large transport vehicles or large transport ships opened their launch units diagonally in the air.

This is the third line of defense on the federal side.

The first line of defense is on the oceans of the Persian Gulf and the Caspian Sea, except for this line of defense here.

Parts of Central Asia and South Asia are also included in the federal volcanic ash removal scope, forming a second line of defense.

Not because I want to be a good guy, but because I want to create a buffer zone. According to the atmospheric circulation, there is a westerly belt in the stratosphere.

Therefore, the volcanic ash erupted by the Yellowstone volcano will quickly cross the North Atlantic, enter Western Asia, then reach Central Asia and South Asia, and finally enter the federal territory.

If we do not establish buffer zones in Central Asia and South Asia, then we must make every effort to block the invasion of volcanic ash at our home borders.

There is not much problem in establishing a large buffer zone for the defense line on the ocean.

On land, a volcanic ash isolation zone with a width of about 100 kilometers can only be established from the northwest Ceylon Ocean to the Caspian Sea.

After the weakening of the first two lines of defense and the slow settlement along the way, only about 1 to 2% of the volcanic ash that can actually reach the federal mainland remains.

But even so, the harm of volcanic ash still needs to be further curbed.

Therefore, rockets need to be fired regularly on the border to further settle the volcanic ash that has slipped through the net.

The current concentration of volcanic ash over the mainland has been suppressed to a very low level, probably only about one ten thousandth of that in the core area of ​​the Yellowstone volcano.

Meteorological monitoring airships deployed in the troposphere and stratosphere also detected large amounts of volcanic ash approaching the border.

emission!

The launch unit on the launch vehicle launches special rockets into the high altitude, and then the rockets detonate at high altitude.

The rocket contains a volcanic ash rapid settling agent developed by the federal government, which can cause volcanic ash to condense into large particles and settle into the ground within ten minutes.

As each rocket detonated in mid-air, a large amount of rapid settling agents were released into the air, and then black snow began to fall in the border area.

That's right, it's black snow.

These black snow are condensed volcanic ash particles.

Although it is impossible to remove all volcanic ash 100%, it can at least remove about 95 to 98%. This is also the back-up that the Federation has prepared long ago.

In Kazakhstan in northern Central Asia.

More than a dozen transport planes, transporting a large number of specially-made rockets, landed at a base near the Caspian Sea.

Kazakhstan, whose economy is still so-so, can only pray that the black snow will not be too severe and that the Yellowstone volcano will not continue to erupt.

Many locals took out gas masks from their homes that were left over from the old Maozi era decades ago.

In fact, their worries are unfounded. Central Asia belongs to the quasi-sphere of influence of the Federation, so naturally they will not watch them suffer serious losses.

In less than two days, freight trains came along the railway line, bringing the first batch of five million sets of gas masks and protective clothing.

There is also a large supply of emergency food, medicine and warm clothes.

This small amount of supplies is just a drop in the bucket for the federation that has entered the red state.

However, these supplies are not free. Instead, they adopt a work-for-relief model, recruiting a large number of unemployed young people locally to control the construction of infrastructure.

Come two days.

Over the sea near the Caspian Sea and the Persian Gulf, warships and tanks on the first line of defense poured hundreds of thousands of tons of rockets into the airflow clouds.

Fortunately, the harm to the environment caused by the black snow settled through the settling agent is minimized, and it is intercepted on the ocean.

Although Central Asia, northeastern West Asia, and South Asia have been affected a lot, they are not as severe as Xizhou and Lucia.

As for North America, the number of direct deaths has soared to 1.73 million, and the number of people injured to varying degrees has climbed to more than 20 million.

There is nothing better than this in hell on earth.

But the eruption of the Yellowstone volcano not only did not stop, but showed signs of expansion. Just after the first large-scale eruption, about 29 hours later, there was another large-scale eruption, and millions of tons of volcanic ash entered the atmosphere.

The area covered by magma has also expanded to a radius of about 183 kilometers. Looking down from outer space, you can see faint fire coming out from under the clouds in Wyoming.
