After 16 years of invasion, it was the darkest year in the world and the moment of dawn.

The city dome system of Puhai City is as calculated in the data, and after a large amount of energy is extracted, the fluctuation line of the decline of the city dome system continues to decline.

After the state prepared as many materials as possible for the land sinking, it was delivered to Puhai one after another, and the engineering team measured the data of each building in Puhai to ensure that the shelter could withstand the impact of the subsidence.

Slogans of support from all sides in distress were hung in cities across the country.

The Eastern Military District ordered the military stationed in Puhai City to make the greatest possible use of planetary artillery. And to the insiders of Puhai City, the 'decisive turning point' will come in eight months.

……

Time passed, and the global city dome system withstood wave after wave of attacks by the outer space fleet.

In September, Puhai City, as inferred from the statistics, completed a "brilliant" annihilation battle after firing two energy cannons, boosting morale, and the protective shield was greatly weakened.

After 40 days, the original rigid shield became an elastic shield.

The shield could not maintain rigidity, which happened during the battle of Delhi and the battle of New Amsterdam, when the politicians in Delhi decided that the biggest problem caused by 'extracting the energy of the city dome for shelling to make the shield elastic' was that the sound insulation was not good, and at most it generated a certain shock wave, so they decided to continue to hang it.

But in fact, when the shield starts to elastically defend, the values of each item have exceeded the threshold, and the shield energy in this shock is not improvised, but decays faster. [This is the same as a dam, when there is a small opening, it is not one more small problem that can be ignored. 】

δ civilization also sensed the 'dam breakdown' of the city dome system, so it began to mobilize warships from all over the world to focus on bombarding the fragile Puhai city dome system.

The battleship opened its massive compound eyes and fired a devastating beam of light, causing the shield to be untenable in its final stages, and the shockwave killed the birds of the entire city.

In the process of bombardment, many cracks appeared in the city dome system for a short time. In the process, some Carcoal Zerg infiltrated the cracks in the city's dome system, engaging in fierce battles with the main battle tanks patrolling the city and the rapid-reacting mechanical infantry.

In the final battle, the humans obtained a lot of key information in Puhai, among them, the combat aircraft completely filmed the process of dismantling the carbon gold zerg from the huge δ civilization warship.

……

Of course, the Lu Shen plan was finally launched.

The scientists of Panxing have not guessed until now: what is the α civilization doing in the core of Panxing. In the process of slowly subsidence, the entire surface plate is changing at an accelerated pace like a vicissitudes of life.

The ground snapped and cracked like a cracker. Then sink into the ground.

This scene makes the human beings of the current civilization fully feel their own insignificance and powerlessness. It's like the insignificance of human beings when they first saw a nuclear explosion.

Monkeys are in the morning and evening, and humans are not.

Such a shocking and frustrating scene can kill all the false pride that mankind brags about before the war. But in this extremely dark scene, a small light appears, and people can still continue to hold on.

[Politicians are psychological masters, so when the people's tolerance has not reached the limit, hide the hole card, and when it is about to collapse, play this card again as a starlight in the dark. In war, what the people need is not false pride, but the feeling that they can work for the victorious trend. If the situation collapses again, as long as the majority of the people feel that they are still doing real things for victory, then there will be no time to 'mourn'! 】

In the great failure of the Puhai land sinking.

Controlled particle beam weapons, which completed the first battle in the sky above it. This is support across 1,200 kilometers.

Compared with the existence of planetary heavy artillery, which relies on α civilization to draw energy from the center of the earth, this controllable particle beam is a technology that mankind has thoroughly understood, and it is a weapon powered by nuclear fusion power stations.

In the first battle, it accurately destroyed sixty-seven δ civilization bombing warships in a state of deployment.

These battleships, which are not cut in the state of shields, are so brittle. The defense and attack of the city dome system are one, and what about the δ warships?

In the next four years, human science and technology entered a blowout period, and air-space fighters, energy radars, and all kinds of advanced weapons appeared dazzlingly.

The era is no longer the situation of a few years ago when human beings were shrinking with a turtle mentality and bombarding with the energy of the city dome system that they did not understand, but the period when they bravely stepped out of the city dome defense and actively looked for the weakness and weakest vulnerability of the enemy's armament.

One regiment after another gradually mastered the tactics of completing dispatch, striking effectively, and retreating quickly in the shortest possible time.

This is the same reason why humans defeated all the big beasts 10,000 years ago and finally occupied this planet.

Humans will excel: hunt during the disadvantaged period when large predators have to hibernate due to lack of food, domesticated animals will use their sense of smell to judge the laws of their activities, and will create traps to produce geographical advantages to offset the advantages of opponents.

Avoid shortcomings: Injured people return to caves to recuperate, and women and children also hide in well-defended settlements to build strength.

……

Of course, the final victory of the panstar is still the arrival of α civilization.

3.4 light-years away, the majestic unknown battleship unfurls and unleashes a deadly bombardment (this massive facility controlling the flow of sub-light particles would have happened by the time the observer of the disk star was seen by the observer of the disk star, due to the theory of invariance of the speed of light).

Disc star human beings have never seen such a perfect blow.

The magnificent beam of light entered the solar system at an angle of 35.2 degrees, like a geometric line, divided into three waves, two of which directly hit the planet Farm and the Thunder Star.

These two gaseous asteroids had the conditions to become stars in an instant, and the internal nuclear fusion was triggered, and six hours later, they emitted a reddish light, and the surface temperature reached 1,000 degrees, which completely sterilized the two planets.

And the beam of light that rushed towards the star of the plate, like a bamboo skewer on a string, pierced the largest warship from beginning to end, and the light even penetrated the thick structural layer. At this moment, δ's huge mothership was like a firefly 'shining' on a summer night.

Four hours after the strike on the delta mothership in the inner orbit of the moon.

Humans reopened their viewing telescopes and saw the complete disintegration of the mothership. The interior has been completely vaporized, and only a shell remains.

As for the clusters of warships in the outer atmosphere, the beams of light that were split out were all wiped out in the space of four femtoseconds. Even stealth warships, which were not detected by humans, did not escape.

The beam energy is so large that each beam of fire that annihilates a battleship in the atmosphere has a yield of 20,000 tons facing upwards.

Fortunately, before the battle, humanity was notified to unlock the upper limit of the city dome system, and overloaded, so that the city dome system enveloped the world at the last moment, just enough to withstand the aftermath of this shelling, so that the ozone in the outer atmosphere would not be destroyed by gamma ray flows, leading to ecological disaster.

Of course, such a clever situation is more likely that α civilization deliberately controlled the scale of the energy beam.

Because all the δ battleships between the orbits of the two gaseous asteroids were wiped out without leaks, except for Panxing, where some remnants of the Zerg were missed that could annihilate humans. After the war, the artillery bombardment of α civilization should consider the upper limit of the Panxing defense system, rather than using saturation firepower to eliminate the swarm.

As a result, the city dome system died completely.

As for what exactly α civilization has done in the center of the earth? So that the energy fluctuations of the global city dome system continue to decline in the later period?

Scientists seem to have the right guesses.

In this shelling, the α civilization showed that terrifying positioning, obviously needing sufficient intelligence support, and the source of information should be the core of the planet, so even if all the cities in the world sink, it will not change the outcome of the δ civilization invasion army in this war

The only thing that has changed for humanity is the fate of its cities to survive, and to gain a cultural memory of 'resisting alien invasions'.

The subject matter provided by this history will be made into countless films in later generations, especially Puhai. When tens of millions of people fall into despair, and then burst out of hope, the complex intersection of various emotions is more worthy of taste than the slightly monotonous persistence of Beiwei City in the war!

……

The total annihilation of the δ invasion force in an instant made all mankind tremble, and all the national organizations in the world passed a new bill on communication with extraterrestrial civilizations with unprecedented efficiency.

The new coalition government is willing to accept all the conditions of α civilization while maintaining the continuity of the race.

However, after the "friendly" radio waves of human beings were sent into space, they sank like a stone into the sea. α civilization, a super-civilization that has never even been willing to reveal its name, is reluctant to explain much when it comes, and has no feelings when it leaves. Like a chivalrous swordsman in the universe, he drifted away after cleansing the evil with a sword.

Where they came from, what they did for the purpose of doing so, and where they are going will be a mystery.

In the years after the war, various experts put forward many hypotheses based on the wartime analysis of the science and technology of the δ civilization. For example, the most famous: "The two higher civilizations are aggregate civilizations, like two brains, fighting against each other's brain cells." ”

After this war, mankind entered a period of rapid development, and formulated a plan to colonize aliens within thirty years.

……

Forty years later, the memory of the war has faded, and all kinds of new buildings are like weeds flooding the monuments, covering the subway where experts and workers went to work. On the Internet, young people pay more attention to the salary stickers of celebrities and space jobs. For the war a few decades ago, there are only a few words "love and hope that support us to victory" to help young people born after them orient their historical memory.

Beiwei City, with the opening of the subway gate, the guide robot dog flashed its electronic eyes, and took the lead in coming out and planning the route. Use the laser to guide the two people behind you.

The gray-haired Saigo pushed Nakahego, who was in a wheelchair, to the observatory.

In his left hand, he has a mechanical prosthetic, pushing the wheelchair through the grassy bricks and tiles in the gaps.

[Zhonghewu was paralyzed in a rocket launch escape, and Zhou Xi lost his left arm in the Great War that year, and after recent technological advances, Xingchong Chong transplanted it. After the successful operation, Zeng Xingchong showed Zhonghewu the progress of contemporary technology, but Zhonghewu shook his head, thinking that it was good to be in a wheelchair. 】

The two stopped on the platform they had worked on and looked up at the sky in sync. One is yearning, and the other is aiming at the direction of a certain star.

After a long time, Zhonghewu said slowly: "Zhou Xi, you say-will the super-civilization still come?" ”

Zhou Xi paused and smiled, "Perhaps, they have been paying attention to us all along!" ”

Zhonghewu laughed, but the laughter caused another cough, and he relented as he tried to pat his back, and said, "Do you still stick to your theory of 'civilizational resonance'!" ”

Zhou Xi nodded slowly: "Yes, all vigorous development has the commonality of heroism and perseverance. Wisdom resonates with each other, and the technological progress of civilization is the echo of this resonance. ”

Zhonghewu looked up at the starry sky, seemed to understand something, and muttered, "Really? If that's the case, then there's no need to worry about anything, just take a bold step forward. ”

A minute of silence. Zhonghewu seemed to be a little tired, closed his eyes silently, and said slowly: "Go back." ”

Zhou Xi nodded in response, his fingertips flashed slightly, and a beam of information particles entered the body of the old man who was about to fail.

Two days later, he passed away, smiling as if he had left in his sleep, without any concern. All kinds of leaders hurriedly participated in the mourning, and left in a hurry.

This great scientist has been working hard for the scientific research and construction of Panxing all his life.

After his death, in the tide of traffic occupied by many celebrities, there was only three hours to be on the list.

……

And thirty years later, at the dawn of the day.

Humans have built fifteen huge magnetic emission towers in the equatorial region, which can allow spacecraft to reach six kilometers per second in the atmosphere, and then start the rocket to successfully reach the first cosmic velocity.

Now, the people who experienced it back then have all died, and the same teachers, warriors, and researchers have left the planet.

Zhou Xi was the last one left behind, and today he once again came to the slope of the mountain where he looked up at the starry sky, and walked tremblingly to the position of the cliff.

Zhou Xi picked up his crutches and tapped the long-winded artificial intelligence next to him to keep it busy, while watching the skyline where the red glow was becoming more and more obvious in the distance.

Zhou Xi sighed a little helplessly: "When I came, the world knew nothing, I was about to leave, and the people who spent their lives couldn't spare their emotions to pay attention. But—"

At this time, the old Zhou Xi stood on the rock peak, looked at the red sun rising in the distance, and smiled: "It's such a world, I dare next time!" ”

……

In the midst of the war, the Panxing people, anxious, worried about their own survival, believe that super-alien civilizations will come to plunder resources and slaves.

After the war, the entertainment industry of Pan Star flourished again, and celebrities quickly occupied people's attention, and politicians quarreled all the time over the ownership of multiple resource point cities on the moon.

As for the causes and final outcome of this war? Maybe they don't have the motivation to figure it out at this stage of civilization.

δ civilization invasion is not about resources and slaves, but for the control of a socialized higher species that has evolved over millions of years, and α civilizations are not alone, and their most precious things have been obtained by their supercivilizations.

He felt that he was very lucky to be able to spend this burning era on this planet with a group of intelligent individuals. The Celestial Migration will forever remember these precious people with an intelligent particle system.

Heroes are priceless, and only those who can remember this greatness for a long time and engrave it in their consciousness can embark on the path of supercivilization.
