Although the gamma ray burst lasted only one minute, the pain it brought to the solar system, the earth, and human civilization was unforgettable and indelible!!

How much casualties did the gamma ray bursts caused by the demise of the star w cause to Earth civilization?

Before interstellar immigrants arrive on Earth or before receiving signals from Earth's defense camps, everything is uncertain about life and death, and it is an unknown number.

At the first moment after the crisis broke out, in the entire Centauri Alpha Galaxy, a large number of space cities, countless spacecraft, escort warships and numerous shuttles shuttles were shuttled like flowing water.

There are a total of 7 Falcon Frigates and 30 Deep Space Resource Development Fleets, a total of 1,500 escort warships and 3,000 Deep Space Resource Development Spacecraft flew to the solar system at the first time at a maximum speed of nearly 0.9 times the speed of light. If nothing unexpected happens, they will arrive on Earth in five years and assume the responsibility of producing hematopoietic blood for the remaining geocentric cities and maintaining stable resource supply.

The plan of clearing the First Space City Group and then rushing to the Earth is also in full swing and carrying ships of people to the Sand Star day and night. According to the arrangement of the Plan A, the Sand Star had already designated a vast special area a few years ago. As the foothold of the Earth's civilized city, urban construction has now begun to appear in scale. Coupled with the remaining space cities and the continuous construction of new cities, it is enough to meet the living needs of nearly 100 million people in the First Space City Group.

The lightweight Space City Group will fly back to Earth at a speed slightly faster than it has been.

In the plan of the Interstellar Exploration Alliance, if the earth's environment is severely damaged, these space cities will become important space bases for the [post-Earth Civilization] and play an important guarantee for the use of various planetary resources of the solar system and the huge project to repair the earth's environment.

At the same time, according to the idea of ​​keeping pace with the times, in the plans of the Interstellar Exploration Alliance and the Federal Government of Interstellar Immigration, the Fifth Space City Group, which is closer to the Earth, will return directly to the solar system after the crisis. Of course, the premise is that the Fifth Space City Group, which is in a dangerous area, will not be hit by excessive gamma ray bursts.

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

"Report to the commander-in-chief, according to the damage model calculation results, the Fifth Space City Group, which is 1.2 light years away from the core explosion area of ​​the gamma ray burst, will suffer a heavy blow!!"

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

"Hard damage, what degree of heavy damage?" Yuan Shichen's pupils shrank and he asked back.

"Because the Fifth Space City Group is directly exposed to space, if there is no celestial cover around them during the gamma ray burst, the chances of the Fifth Space City Group losing communication capabilities will be as high as 85.2%. It is expected that 41.4% of electronic devices will be destroyed by powerful radiation, including the Space City Life System, Ecological Circulation System, and Energy System."

The middle-aged scientist frowned while reciting the data. It seemed that he was under a lot of psychological pressure at this moment.

"How is the injury situation?" Yuan Shichen asked.

"Although the outer layers of the living and working areas of Space City are equipped with good radiation-proof armor. However, the attacked outermost residents will still be injured at extremely high doses of radiation. Perhaps, they will not die immediately, but will develop symptoms of proliferation and intermittent death within the next 72 hours."

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

The so-called proliferation death means that after a cell is irradiated after one or several division cycles, it loses the ability to continue proliferation and dies, which is also called delayed death. Interstitial death refers to the cell's death without dividing after being irradiated, and it starts to die within a few hours, also known as immediate death.

Yuan Shichen knew the meaning of these nouns. In this case, almost all the residents of the Space City who received high doses of radiation in the outermost layer would die in pain in the end, just like the old people who stayed on the surface and were on the back of the earth when they were attacked.

"What is the radiation level in other areas of the Fifth Space City?" Yuan Shichen continued to ask with a frosty face.

"Although there are differences in levels, 50% of the areas of the Fifth Space City Group will be contaminated by radiation from high-energy rays." 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 [cleaners] in the Chernobyl nuclear accident in the former Soviet Union, and the DNA structure in the cell will be damaged, and within the next 10 years, the symptoms of macroscopic irradiation will appear."

(In the Chernobyl nuclear disaster, the staff responsible for restoring and sorting the nuclear radiation area are called "cleaners". The cleaners receive very high doses of radiation during the cleaning process. According to Russian estimates, about 300,000 to 600,000 cleaners enter 30 kilometers from the reactor to remove radiation pollutants within two years after the disaster. They made great sacrifices, and they cleaned up most of the nuclear pollution.)

Although the report describes only some cold data, there are countless living lives behind it. 60%! This means that 60 million people will live in the shadow of radiation from then on, and watch their lives continue to decline and wither and be at a loss!

For the tragedy that had already happened, Yuan Shichen could only choose to remain silent. This was a disaster for all mankind. Excessive sadness was useless. What he was thinking about now was how to carry out rescue more efficiently.

"I want to go back to the earth and take a look!!"

After several thoughts, Yuan Shichen finally made a decision

Six hours later, a silver-gray command ship shone with dazzling flames under the guidance of many frigates and left the Central Space City - Sunshine City, left the Sand Star System, and flew at high speed toward the location where the solar system is.

That was the core-level spacecraft with the highest navigation capabilities that Yuan Shichen, the commander-in-chief of the Post-Interstellar Exploration Alliance and the scientific leader of human civilization.

According to the plan, the command ship joint fleet will take five years to reach the earth (even if it is flying close to the speed of light, the time flow will slow down, but the time outside remains the same, and it is still five years). With today's interstellar travel dormant technology, he only needs to sleep and wake up to reach the earth.

However, Nai Chen did not choose to hibernate during these five years. Because he is the leader of the entire interstellar immigration team. After the crisis broke out, there were countless important tasks that he needed to make decisions. The most important thing was that the command ships returning to the solar system could obtain post-disaster feedback signals from the Fifth Space City Group and the Earth's defense camp as soon as possible.

When Yuan Shichen set off:

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

During the journey of the command ship joint fleet returning to Earth, Yuan Shichen would take some time to inspect the third, fourth and fifth Space City Group (the fleet also happened to provide necessary resources).
Chapter completed!
