The star WR104 is located in the constellation Sagittarius (the constellation Sagittarius and the constellation Centauri are very far apart, with Sagittarius in the north and Centauri in the southern sky), and there is a slight difference in its distance from the solar system and the Alpha Centauri galaxy. Pen & Fun & Pavilion www.biquge.info

Therefore, whether it is the solar system, the Alpha Centauri system, or the third, fourth, and fifth space city groups on the way, the time and degree of their impact are not exactly the same, and they cannot warn each other, because gamma-ray bursts will arrive faster than the warning signals issued.

On this day, the level of cosmic radiation in the entire Alpha Centauri galaxy suddenly increased by nearly 1,000 times.

Gamma-ray bursts have finally spread to the entire Alpha Centauri system.

As a result, the extreme scenario feared by the crisis research team did not materialize, and the gamma-ray burst traveled through the solar system with a high concentration for some unknown reason.

So, the energy that ripples through the Alpha Centauri galaxy is not too striking. On the other hand, this gamma ray burst is within 0.33 light-years of the solar system, but it deals extremely powerful critical damage!!

......

At this time in all corners of the Alpha Centauri binary star system. Countless scientists are busy like ants on a hot pan in every laboratory, in every astronomical observatory, in every office.

"Erupted!! It's an explosion! It's an explosion! ”

"Quick! Fast! Block! I want the latest observations!! ”

"The solar system has been attacked!! The Earth has been attacked!! ”

"Oh God!! Oh God!! Pray for the earth!! ”

"Oh my God, the intensity of this gamma-ray burst is at least 5 times stronger than the budget!!"

"It's over, it's over, a 5-kilometer-deep underground city is simply not enough!!"

"I wonder what happens to the underground city on the far side of the earth?"

......

In fact, not only the scientists in the Interstellar Exploration Alliance, but also the humans in all the interstellar immigration camps made a mess at this moment.

In the space city, you only need to look through the porthole at the constantly flickering aurora on the poles of several planets such as the Sand Star, and it will be clear that the sword of Damocles that has been hanging from the neck of human civilization has finally fallen.

In the core area of the Interstellar Migration Central Space City, Sunshine City, in the administrative building of the headquarters of the Interstellar Exploration Alliance.

Yuan Haochen's expression was grim, and his face was like frost standing in the center of the command center. Countless scientists are around him, and every minute a team leader comes to update him on the latest developments.

It is calculated that the Third Space City Group is affected at a distance of about 3.8 light-years from the core region of the gamma-ray burst, and the Fourth Space City Group is affected at a distance of about 2.7 light-years from the core region of the gamma-ray burst.

If the intensity of gamma-ray bursts observed in the Alpha Centauri galaxy is calculated, there should be no other serious problems in the third and fourth space city groups, except for a small amount of sensitive electronic equipment exposed to space that will be damaged.

However, the location of the Fifth Space City Group is only about 1.2 light-years away from the core region of the gamma-ray burst, and although it is not in the high-risk area within 0.33 light-years, it is still very dangerous.

According to the model calculation, the crisis research team gave the following classification range of danger areas:

0-0.33 light-years away from the core area is the dead zone;

0.33-1 light-years away from the core area is a high-risk area;

1-2 light-years away from the core area is the danger zone;

2-4 light-years away from the core area is the transition area;

A relatively safe area of more than 4 light-years away from the core area;

"Turn on all strong points to prepare the communication module, and continue to call the Earth to stay in the defense camp, as well as all the Space City groups on the route!!"

"Yes!!"

"Order the 1st, 3rd, and 10th Falcon Convoys to meet the Fifth Space City Group at their maximum speed (0.9 times the speed of light)!!"

"Yes!!"

"Order the second, sixth, eighth, and ninth Falcon convoys, and the 30th-50th Deep Space Resource Development Fleet to fly directly to the solar system at maximum speed!!"

"Yes!!"

"Notify the federal government and implement Plan A immediately!!"

Plan A is an emergency plan approved by the federal government, and the main content is: quickly organize the residents of the first space city to land on the sand star, empty all space cities, and then send these space cities to the direction of the solar system for rescue purposes.

......

After Yuan Haochen issued a series of orders, he continued to fall silent.

"It's so powerful! It's so precise!! Yuan Haochen pondered in his heart, "Why is there such a gamma-ray burst attack!" ”

Heaven is going to kill me!! The universe is going to destroy the civilization of the earth!!

This was the first thought that came to Yuan Chen's mind, and it was the extremely bad situation he expected.

"How can the [City in the Center of the Earth], which is only five kilometers deep, withstand such a terrifying energy raid! We still underestimate the power of the universe! ”

"Now, we can only hope that the geocentric city located on the far side of the earth can survive the crisis!"

Yuan Haochen's brain was racing, and countless possibilities passed through his mind.

The crisis has erupted, and the 4 billion elderly people (and some young people) who have been left behind on the surface of the earth must have died and died for a long time, and the remaining inhabitants of the geocentric cities are still unknown whether they will live or die. The most important task at the moment is to rescue, and to rescue as quickly as possible!

According to the damage model built by the crisis research team, at least 52.1% of the Earth will be hit head-on after the gamma-ray burst attack, and it will take at least 50 years for the residual radiation after the gamma-ray burst passes through the earth to be basically reduced.

In addition, 62.4% of the atmosphere is expected to be destroyed, meaning that the Earth's standard atmospheric pressure will only be one-third of its original level, and worse, the rarefied atmosphere will be filled with toxic gases that will not be able to support breathing. Finally, when the ozone layer is completely destroyed and the earth loses its protective umbrella, a large amount of cosmic radiation will further deteriorate the ecological environment on the earth's surface.

In summary, if the residents of the geocentric city only rely on their own strength, it will be an extremely arduous and protracted project to restore the earth's ecological environment. Most scientists are even skeptical that the remaining camp on Earth still has this ability.

So far, it is impossible to predict how many [City in the Center] will survive the onslaught of gamma-ray bursts. Because, the 52.1% of the area that has been hit head-on is critical.

This is also a paradoxical question, and from a theoretical point of view, one should hope that the 52.1% of the area will have more oceans and less land.

More often than not, however, people pray that their relatives, friends, or the region of their country of origin will be protected from a frontal attack.

But no matter what, the remaining camp on Earth will definitely suffer a lot of vitality, or even worse, and a large number of casualties will definitely be unavoidable......
