In December 2124, 155 years had passed since the first year of the crisis, 1969. Pen % fun % Pavilion www.biquge.info

Thirty years after the First Space City Group left the solar system, they have entered the Alpha Centauri system and are about to arrive at the Sand Star.

The Second Space City Group (where the former Hao Chen is located) has been out of the solar system for 20 years, at this time 3.1 light-years from Earth, and has entered a deceleration phase.

The Third Space City Group has been out of the solar system for 12 years, 1.5 light-years from Earth, and is in the stage of stable navigation.

The Fourth Space City Group has been out of the solar system for 6 years, 0.3 light-years from Earth, and is still in the accelerated navigation stage.

......

This day is the day that the Fifth Space City Group left Earth.

At the former Star Exploration Alliance headquarters lookout, a middle-aged commander looked at the sky with a heavy face.

"I'm sorry, Commander-in-Chief, and Commander Durunik, I didn't get what I had promised. The Fifth Space City Group, which was originally planned to be completed in five years, ended up taking an extra year. ”

The middle-aged commander's expression was a little gloomy, the cold wind in December was quite cold, not to mention that this was the Tibetan Shisha Bangma Peak on the roof of the world.

Looking at the past, there is snow everywhere. Suddenly, another cold wind blew in the middle of nowhere, and the middle-aged commander instinctively shivered. He quickly tightened his uniform jacket a little more, then straightened his chest and continued to look at the sky.

Nowadays, the situation of the earth has long been much worse than before, although all manpower and material resources have been focused on the construction project of the space city, but it is still overstretched, and it is impossible to successfully complete the construction goal of the space city according to the plan. Being able to complete the construction task of the Fifth Space City Group within 6 years is already the result of the left-behind human camp trying their best to get it back.

At present, in the left-behind world on the surface of the earth, all the people have been forcibly relocated to the central city by the government, and countless small and medium-sized towns have been abandoned, deserted, and dilapidated. And even in the central cities, there is a strong atmosphere of depression.

The reality is cruel, this is the current situation of the camp of dead humans who remain on the surface.

A hundred years ago, no one could have imagined that the human world, which was changing with each passing day and had a bright future, would encounter such a tragic scene.

Nearly 3 billion people are hiding underground, 550 million have fled in space, and nearly 4 billion elderly people are left on the ground waiting to die.

Of the 4 billion people left behind on the ground, the number of people over the age of 50 has reached more than 90% due to the passage of time and the problem of exchanging with the population of the geocentric cities (the old people go out and the young people go in), and the total population continues to decline sharply.

This is also the reason why the construction of the space city is becoming more and more difficult. There are fewer and fewer young people who can work in space, and if it weren't for the high wages offered by governments to recruit labor in [Geocentric Cities], and the promise that those who participate in the construction of space cities will have priority access to Geocentric Cities and Space Cities. The progress of the construction of the Fifth Space City Group will be delayed for at least another three years before it is completed.

......

At the 2nd Space City Group, the Central Space City - Sunshine City, the highest joint meeting of the federal government.

Officials from the three central federal authorities (legislative, executive, and judicial), the Interstellar Exploration Alliance, and the member states of the Federation are gathering here to discuss a number of policy priorities.

The oval-shaped venue is magnificent, with countless spotlights dotted on the top of the venue like stars, and a two-story platform around the main stage like a crescent moon, with nearly 10,000 seats looking layered and scattered.

"Hello everyone, I will next speak on behalf of the Interstellar Exploration Alliance."

Standing on the podium in the center, Yuan Haochen looked vigorous and radiant.

"In three months, the First Space City Group will arrive in the Alpha B star system of Centauri, in the B star system, there are a total of two terrestrial planets, Alpha Centauri BB1 and BB2, perhaps everyone will be more familiar with their unofficial names, Sand Star and Dung Star."

"What we need to discuss today is the next course of action that the First Space City Group should take after arriving at Sand Star."

Yuan Haochen's sonorous voice spread to every corner of the venue through the voice circulation system.

"First, I'd like to talk about the latest gamma-ray burst hazard assessment results."

"Although the operation of star WR104, including the entire solar system and the Alpha Centauri galaxy, is dynamic, through the computational observation of large-scale space in the universe, we have strangely found that the star WR104 has shown a certain degree of linkage with the solar system. So, when we look at star WR104 for nearly a century, the solar system happens to be in the path of a deadly gamma-ray burst. Although we can't explain the reason behind this, we can be sure that this will be devastating news for the solar system through a lot of calculations. ”

(When we look at star WR104 through the light of the previous minute, we can calculate that its axis of rotation is facing the Earth, and then the next minute a gamma-ray burst may reach the Earth and destroy humanity, the process is dynamic.) ）

"It's like a lethal rifle-style precision strike, and its coverage is within 0.32~0.35 light years. If the solar system were hit at this moment, a gamma-ray burst would destroy most of the Earth's atmosphere in a matter of seconds, our Earth's surface would be covered with carbon monoxide, the ozone layer would disappear, most of the oceans would likely evaporate, and life on the Earth's surface would be completely wiped out. Moreover, this crisis will inexorably sweep across the entire solar system. ”

"Of course, with the specific situation of the linkage between the star WR104 and the solar system, the power of the gamma-ray bursts that actually arrive in the solar system will vary, which is one of the reasons why the results of the current crisis assessment are different from those of a century ago." Yuan Haochen continued to introduce.

"Although the crisis research team made a judgment based on the mass, volume, rotation angle, rotation speed of the current star WR104, as well as its distance from the Alpha Centauri galaxy and other factors, the interior of the Alpha Centauri galaxy about 4 light-years away from the path of the gamma-ray burst is basically safe, but we still cannot take it lightly and must be fully prepared!"

"Therefore, in order to prevent extreme situations, the Interstellar Exploration Alliance suggests that the original plan to land on Sand Star be changed, and all space cities must continue to hide behind the planet in order to seek maximum protection!" (To be continued.) )
