Although the gamma-ray burst only lasted for a minute, the pain it brought to the solar system, to the earth, and to human civilization is unforgettable and indelible!!

To what extent did the gamma-ray burst generated by the extinction of star WR104 cause casualties to Earth's civilization?

Until interstellar migrants arrive on Earth, or receive signals from Earth's defense camps, everything is uncertain and unknown. Pen fun and pavilion www.biquge.info

In the immediate aftermath of the crisis, in the entire Alpha Centauri system, a large number of space cities, countless spaceships, frigates, and vast shuttles shuttled like flowing water.

A total of 7 Falcon convoys and 30 deep space resource development fleets, with a total of 1,500 frigates and 3,000 deep space resource development spacecraft, flew to the solar system at a maximum speed of nearly 0.9 times the speed of light. If nothing else, they will arrive on Earth in 5 years and will be responsible for bloodstaining the remaining geocentric cities and maintaining a stable supply of resources.

And the A plan of emptying the First Space City Group and then rushing to the aid of the earth is also in full swing and is being carried out in an orderly manner. Massive shuttles carry boatloads of people day and night to the Sand Star. According to the arrangement of Plan A, Sand Star has already demarcated a vast special area a few years ago, as the foothold of the earth's civilized city, and now the urban construction has begun to take shape, with the remaining space cities, as well as the new cities that continue to be built, it is enough to meet the living needs of nearly 100 million people in the original First Space City Group.

The Light-Loaded First Space City Group will fly back to Earth at a slightly faster pace than it came.

In the plan of the Interstellar Exploration Alliance, if the earth's environment is seriously damaged, these space cities will become an important space base for [post-Earth civilization], and play an important role in the use of the resources of the planets in the solar system and the huge project of repairing the earth's environment.

At the same time, in accordance with the idea of keeping pace with the times, in the plans of the Interstellar Exploration Alliance and the Interstellar Immigration Federal Government, after the crisis, the Fifth Space City Group, which is closer to Earth, will return directly to the solar system. Provided, of course, that the Fifth Space City group, which is in the danger zone, is not overly impacted by gamma-ray bursts.

......

The core area of the Central Space City, the administrative command center of the headquarters of the Interstellar Exploration Alliance.

"Report to the Commander-in-Chief, according to the results of the damage model, the Fifth Space City Group will be severely damaged 1.2 light-years away from the core outbreak area of the gamma-ray burst!!"

A middle-aged scientist reported to Yuan Haochen with a serious expression.

"Hard, to what extent!?" Yuan Chen's pupils shrank and asked rhetorically.

"Because the Fifth Space City Group is directly exposed to space, if there is no celestial cover around them when the gamma-ray burst passes through, then the probability that the Fifth Space City Group will lose its communication ability will be as high as 85.2%. It is estimated that 41.4% of electronic equipment will be destroyed by powerful radiation, including the space city's life support system, ecological circulation system, energy system ......"

The middle-aged scientist frowned tightly as he read the data, and it seemed that he was also under a lot of psychological pressure at the moment.

"What about injuries?" Yuan Haochen asked.

"Although, the outer layers of the living and working quarters of the Space City are equipped with good anti-radiation armor. However, the outermost inhabitants of the attacked layer are still exposed to extremely high doses of radiation. Perhaps, they will not die immediately, but they will have symptoms of proliferative death and interphase death within the next 72 hours......"

The middle-aged scientist's voice became deeper and deeper, and in the end, he no longer had the courage to look directly into Yuan Haochen's eyes.

The so-called proliferation death means that after one or several division cycles after irradiation, the cell loses the ability to continue to proliferate and dies, also known as delayed death. Interphase death refers to the fact that cells begin to die within a few hours without dividing after being irradiated, also known as immediate death.

Hara was well aware of the meaning of these terms, and in such a situation, almost all of the residents of Space City who received a high dose of radiation in the outermost layer would eventually die in agony, just like the old people who remained on the surface of the earth and were on the far side of the earth at the time of the attack......

"What is the level of radiation exposure in the rest of the Fifth Space City?" Yuan Haochen continued to ask with a frosty face.

"Although the levels vary, 50% of the area of the Fifth Space City Group will be contaminated by radiation from high-energy rays." The middle-aged scientist Shen continued to read the report in his hand, "If it is not handled properly, more than 60% of the residents of the Fifth Space City will receive a very high dose of radiation like the [clean-up] in the Chernobyl nuclear accident in the former Soviet Union, and the DNA structure in the cells will be damaged, and in the next 10 years, the symptoms of macroscopic radiation will be shown one after another......"

(In the case of the Chernobyl nuclear disaster, the people responsible for restoring and organizing the area of nuclear radiation are known as "clean-up people.") The cleaners were exposed to very high doses of radiation during the clean-up process. According to Russian estimates, about 300,000 to 600,000 clean-up personnel went within 30 kilometers of the reactor to remove radioactive contaminants within two years of the catastrophe. It was they who made the great sacrifices, and it was they who cleaned up most of the nuclear contamination. ）

Although the report describes only some cold data, there are countless lives behind it. 60%！ This means that 60 million people will henceforth live in the shadow of radiation and watch their lives continue to decay and wither!

For the tragedy that has happened, Yuan Haochen can only choose to be silent, this is a disaster for all mankind, excessive sadness is no longer helpful, and what he is thinking about now is how to carry out rescue more efficiently.

"I'm going to go back to Earth to see it myself!!"

After thinking about it several times, Yuan Haochen finally made a decision.

......

Six hours later, a silver-gray command ship, under the guidance of many frigates, left the central space city, Sunshine City, left the Sand Star System, and flew at high speed towards the location of the solar system.

It was the core-level spaceship with the highest sailing ability that Yuan Haochen, the commander-in-chief of the Post-Interstellar Exploration Alliance and the scientific leader of human civilization, was aboarding.

According to the plan, it will take five years for the command ship Combined Fleet to reach Earth (even if it flies close to the speed of light, the flow of time will be slow, but the time in the outside world remains the same, it is still five years), and with today's interstellar travel hibernation technology, he only needs to sleep and wake up to reach Earth.

However, Yuan Haochen did not choose to sleep in these five years. Because he is the leader of the entire interstellar migration team, after the outbreak of the crisis, there are countless important tasks that need him to make decisions, and the most important thing is that the command ship United Fleet that returns to the solar system can get the post-disaster feedback signal from the Fifth Space City Group and the Earth Defense Camp at the first time.

When Yuan Haochen set off:

The Third Space City Group is located 0.6 light-years from the Alpha Centauri Galaxy, the Fourth Space City Group is 1.9 light-years from the Alpha Centauri Galaxy, and the Fifth Space City Group is 3.1 light-years from the Alpha Centauri Galaxy.

On the way back to Earth for the Combined Fleet of Command Ships, Hara will also take some time to inspect the 3rd, 4th, and 5th Space City Groups (the fleet also happens to be replenishing the necessary resources).
