Before July 3, 2112, no one could have imagined that humans could go crazy to this point, just as before September 11, 2001, no one could have imagined that a madman would hijack a civil airliner to hit a skyscraper.

In Zhao Yu's time, Hollywood screenwriters dared to let terrorists rush into the White House with guns, kidnap the president, and use an entire city as a bargaining chip to negotiate with the government, but they didn't dare to really destroy a city that existed in reality, let alone kill all mankind; If this must happen, then the culprit must be aliens, superpowers, natural disasters...... In short, it won't be earth humans, and earth people can't be crazy to this extent.

Until July 3, 2112.

The Fourth World War is still going on, two years ago the technological exchange of the European Community stimulated all the forces on the planet, the war was fought in a more intense way, and the uncontrolled military organizations such as terrorist organizations, mercenaries, private armies and other uncontrolled military organizations also exploded, finally reaching their peak on this day.

A group of extremists who have been fighting the United States for more than 100 years, and even the United States has not been able to eradicate the roots with extraterrestrial technology, entered Wyoming on the day before the 2112 American National Day.

And then they did what only the craziest science fiction novels would dare to do - they detonated the Huangshan volcano.

Just as scientists have been fearing, the supervolcano, which has been dormant for more than 600,000 years, has erupted like a giant bomb. The seismic waves caused by the eruption were so strong that half of the earth's detection instruments failed, the huge shock wave pushed everything out of a radius of hundreds of kilometers on the spot, the volcanic ash plunged the North American continent into darkness in a few hours, a third of the Rocky Mountains disappeared without a trace, and the terrain of Wyoming, Idaho, and Montana, adjacent to the Yellowstone volcano, was almost completely changed by the earthquake, and the earthquake spread to North Dakota, South Dakota, Nebraska, Utah, Colorado, Nevada and other states. Fifty million Americans died as a direct result of the disaster, and another 20 million later died from air pollution, earthquakes, and other secondary accidents.

This is the worst man-made disaster in human history, known as the "Great Eruption", in which the North American continent was shrouded in darkness when the Earth was seen from space for a full month.

For the first time in history, the Buttermins took the initiative to release into the atmosphere what they called "suppression particles", binding the dust and volcanic ash that filled the atmosphere to the North American continent, so that the long winter did not spread to the whole world. But Americans are not grateful to the aliens, because for the next two decades, the United States was in darkness.

Agriculture collapsed, ecology collapsed, and then industry collapsed. If the eastern part of the United States, which borders the Atlantic Ocean, can still receive some rescue, the western part of the United States has completely become a post-apocalyptic world. Suppressing particles would rip everything flying in the sky off, and the unbearable poison gas and lava were still raging along the Rocky Mountains, cutting off the road to the west almost entirely, with only southern Texas leaving a narrow corridor to reach New Mexico, through which some help could be provided further west.

But New Mexico's rescue teams reached Arizona and California at most, and further north, closer to Yellowstone, Nevada, Oregon, and other places, people can only describe the hellish scene there through the lucky ones who escaped intermittently.

Under these circumstances, the new President of the United States made a decision: to unite with the European Community with the remnants of American power in order to guarantee the greatest interests of the United States, and the western part of the United States, which seemed to have no hope in a bottomless pit, needed temporary ...... Abandon.

Stop the supplies, stop the rescue. There was no salvation in the west, and in any case, it was impossible for that area to re-establish its cities in a hundred years. Rather than a steady stream of desperate rescues, it would be better to let the survivors of the West go to the East and wait for the wounds of America to heal before starting to build the West again.

But policymakers forgot ...... Or perhaps it was a deliberate attempt to ignore the fact that most of the western survivors would never make it to the east alive. On the other hand, after learning that the West had been abandoned, almost all the citizens of the West who were still alive were outraged, and hostility spread wildly among the people who survived the catastrophe, and during the twenty years from the tenth to the thirtieth year after the eruption of the Yellowstone volcano, the opinions of the East and the West became more and more divided, and the last remnants of the Westerners formed the "West Coast Republic" and declared their independence from the United States of America, which of course caused a strong reaction from the East, which had already breathed a sigh of relief to attack the West, But it further aroused the anger of the west: "When we are desperate, you give up on us, and when we have to struggle to survive on our own, you want to stop it?!" ”

More Westerners joined the West Coast Republics, and the era of the Great Schism finally reached its peak. In 2133, the Second American Civil War broke out.

Fighting began in Texas and New Mexico, but as the weather on the North American continent gradually stabilized, the northern front also began, and the eastern army began to march from the north through Canada, and the front quickly divided into two fronts, north and south. But the eastern army, which thought it was sure of victory, was hit head-on: the "West Coast National Army" they faced still maintained a fairly strong fighting force, and the quality of its soldiers did not look like it had suffered several years of famine.

It is clear that some other forces are involved in this war.

The eastern policymakers, who had been busy restoring order at home, looked up and finally found that the world had changed.

Because of the eruption of the Yellowstone volcano, almost all the troops of the US military bases abroad tried to rush back to the US mainland at the first time, and the vacuum left by it was quickly filled, for example, in Europe, Russia expanded its sphere of influence to the Balkans in one go, and even the German border could see the arrogant double-headed eagle flag, which is also the reason why the European Community was eager to strengthen ties with the United States -- after several years of fighting a world war worthy of the name, the giant bear in the east was already waiting for this moment to go crazy.

In order to counter Russia, the European Community had to turn more attention to the eastern front, and for the United States, it was on its own to deal with the rebels in the west.

But the West Coast Republic is not alone.

Hawaii suffered a lot of losses from the tsunami caused by the Yellowstone eruption, but it finally recovered and inherited a nearly complete Pacific Fleet, a powerful naval fleet that was one of the biggest battles of the West Coast Republics, and with Hawaii as a relay station and rear base, Asian aid continued to arrive.

Initially, Asian aid to the West Coast Republic was mainly food, but after the West Coast decided to hand over a batch of military technology, they received a variety of military equipment in the list of aid they received. The current situation in Asia is very delicate, Central Asia is almost all controlled by Russia, West Asia is divided by several major powers, as for East Asia...... Now the dust has settled.

Judging from what Zhao Yu knew, the whole process was as follows: after the Seventh Fleet hurried to Hawaii, Japan could not wait to jump out and declare that it had been a "abnormal country without an army" for too long, and that they wanted to gain more rights in East Asia - the hegemon who had suppressed itself for a hundred years was gone, what a joyous thing! No one can stop us from rising again, and if anyone doesn't believe it, let's try our will!

But their tragedy lies in the fact that there is also a behemoth on the continent that is a neighbor, and who has also put up with the Americans for a long time and does not intend to give up this opportunity.

To be sure, Japan's maritime military strength is ahead of East Asia in terms of scientific and technological level because of various support from the United States in the past, but it is a pity that when the numerical superiority reaches a certain level, the technological level is not very good. In just three months, the Japanese lost almost all their warships in several naval battles with great disparity in power, and retreated to the four mainland islands in disarray, and when the formation of warships flying the August 1 flag bypassed most of Japan and appeared in Tokyo Bay in the east, the Japanese had only one choice left, that is, to continue to be their abnormal country.

And while that neighbor was holding back Japan's indiscriminate fighting, he still had the spare strength to send the South China Sea Fleet to Southeast Asia to express a cordial and clear greeting to the coastal countries: Who else is not convinced?

The situation is clear, after the Americans leave East Asia, there is only one country that is qualified to be the boss.

There is no suspense about what happened after that, the process of deciding the hegemony of the western Pacific coast took nearly half a year, but after this was done, it only took a month to unify the region. Now, the Commonwealth of Nations, known as the Western Pacific Alliance, or WPA (WPA), is the most important ally of the West Coast Republics, and its sphere of influence includes all of East and Southeast Asia, a part of Siberia (Russia has "trusted" about a million square kilometers of land to raise capital for westward expansion), and India has joined in with its nose (after being beaten equally hard and losing several eastern states). In addition, Australia and New Zealand, two peripheral countries that have expressed their willingness to "assist" the WPA, are considered partners. Even before the establishment of the West Coast Republic, the WPA began to provide aid to western North America, and every month a large amount of supplies from Japan and Australia were loaded onto cargo ships to Hawaii, and from Hawaii to the western part of the North American continent.

Of course, WPA has never been in a loss-making business, and the main price paid by the West is technology, all technology. WPA people (mostly Chinese) came to the West, took everything they were interested in, from drawings and data to physical equipment to UC Berkeley and Stanford University, all packaged, and some lucky former American West citizens (mainly technicians) were also allowed to settle in the WPA's sphere of influence, and WPA provided them with factories, manpower, laboratories, and funds - as long as you were researching technology that could allow humans to escape the solar system, or defend against that gamma bomb; You can also try to research something else, and try your luck at throwing it to the Bartmins after you make it, and maybe unlock some technology?

Of course, all this is too far away for those who are still fighting on the North American continent.

The second civil war in the United States has lasted for more than 40 years, whether it is the WPA, the Russian-led "Slavic United Front", or the "Atlantic Alliance" formed by the eastern United States and the European community, they all tacitly use this battlefield as a testing ground for various new technologies, especially the research of "mutants", and almost 90% of the research laboratories are located on the North American continent. Neither side has any intention of letting the war stop - there are experiments, technology, and order in this land, so should we put an end to all this and move the research laboratory to Africa and South America, which are in a state of misery? Those two continents are now the complete dark zone.

And for the warring parties, the United States of America, which was once united and the strongest in the world, has long been a thing of the past, the soldiers on the battlefield are all young people born in the war, and dislike the other side is an established matter without doubt, the people in the east think that the west is all fools of the republic, and the westerners think that the east is all the alliance bastards who take advantage of the fire, and only those who are sixty or seventy years old or even older miss the pre-war time and dream of the reunification of the country.

Zhao Yu was fortunate that his freezer was stored at the University of Oregon - one of the few places directly controlled by the Buttermins people, even the crazy earthlings would not dare to enter it, and the destruction of the Yellowstone volcano did not hurt it, so Zhao Yu was able to wake up smoothly in the order of the recovery list, by this time the suppression particles had been working for decades, the atmosphere had returned to a relatively viable environment, and he escaped the hellish period of the first few years.

The problem with Zhao Yu is that he doesn't have the slightest sympathy for this war, which has lasted for more than forty years.

For him, there is not much difference between the western and eastern Americans, he doesn't have much ill feeling towards aliens, and he enlisted in the army just to find more reality and presence, after all, after being paralyzed in bed for several years, as a young man still has to find something exciting to do. Anyway, it's not fighting with compatriots in your own homeland, what are you afraid of?

So here he is now, in the cockpit of a spider chariot, having just evacuated a battlefield and is heading for a new one.

But now, for the first time, he found that his troubles became: Why am I fighting this battle? What is the point of this war for me?

Is it aliens' fault? But aliens have no obligation to help earthlings, and even because of aliens' faster-than-light communication, the earth has more than two hundred years of preparation time, otherwise humans will wait until there is one more bright star in the sky to suddenly realize, and then it will be too late.

Shouldn't earthlings use war as a means? But this is the only effective means that the earthlings can find, and after trying the exhausting and inefficient alliances, only the imminent death and the constant emergence of strange technologies can stimulate the development of humanity, and humanity has no time to try more methods.

So who else can be blamed? What else? Could it be that cursing God with the middle finger to the sky every day can solve the problem?

Although he knew from the beginning that war was necessary, he felt a little tired after seeing his comrades-in-arms whom he had never known a day ago choosing to die without hesitation in order to cover their evacuation, and fighting with people who were originally comrades-in-arms...... Of course, the more elegant way to say it is that he is more hypocritical now.

"We might be in trouble." A voice interrupted Zhao Yu's train of thought.

Borg covered his headphones with a serious expression and listened to the content of the communication channel: "Sergeant Hartmann, they were attacked ten minutes ago, and now the communication has been completely cut off...... Guys, get ready for another big fight. ”

Gabriel, who didn't know when he returned to the cockpit, changed the magazine for his rifle, silently opened the cockpit canopy, and entered the firing position.

Zhao Yu stared blankly at the prospect.

Suddenly, a pair of hands grabbed his shoulders and shook him desperately: "Are you okay?" You've been in a daze with a serious expression since just now, huh? ”

Zhao Yu looked at Christine's eyes, took a few deep breaths, and let himself smile into a smile: "Some old people's boring troubles...... Don't worry. ”

The historical process of this chapter, please don't go into the details, well. Plot needs.

It seems that it is more appropriate to post this chapter on September 11th?

In other words, why has the capital of the United States become a forbidden word?
