The Firefly Galaxy is a star system formed by three gathered stars as the center and all the celestial bodies of size that are bound by their gravity. The main star was named Firefly Zodiac by the pioneers who arrived here 680 years ago, and the other two companions were named Ares and Tyre. The only planet in the galaxy suitable for human habitation is called New Earth Star to commemorate the human mother planet far away thirty-eight light years away.

In the following hundred years, three groups of immigrants had reached the New Earth Star one after another. The New Earth Star began to flourish, but... People have good fortune and misfortune, and the sky has unexpected winds and clouds. In the 117th year of Firefly, a sudden explosion of supernova in the system cut off the connection between the New Earth Star and the parent star. The fourth batch of immigrant fleets who should have arrived at the New Earth Star in the 120th year of Firefly, have disappeared from now on...

People were able to calm down at first. After all, during the great development of the universe, the interstellar journey was full of various unknown risks. It is common for the immigration fleet to delay the itinerary. However, as time goes by, more than 60 years have passed, there is still no news from the parent star. The immigration fleet has no news. The endless fear of the unknown future, the helplessness, resentment, and even hatred of being abandoned by the parent star have grown and expanded among people.

In the 189th year of Firefly, the 72nd year after the outbreak of Supernova, a riot occurred at Saxon base. The riots quickly spread to the other three bases like a prairie fire. The first civil war between Firefly Mankind began since then. Although this war did not last long, it only took two and a half years, the losses caused to Firefly Mankind were extremely heavy.

Almost all four bases were broken into messes, and the direct personnel losses were as high as 73%. In the five years after the truce, about 76,000 people passed away one after another due to many reasons such as harsh external environment, old war injuries, shortage of drugs and medical equipment, and insufficient food supply caused by climate change in the Firefly Star. The total number of people who survived was less than 20,000! The population size of this population is 6.3 times that of the human mother star, and the species is extremely abundant. Among them, there are many Firefly Star, which has a powerful threat to humans, which is like a drop in the ocean. It can be said that a little more natural disaster and man-made disaster is enough to make Firefly Star genocide!

Compared with the tragic losses of personnel, the heavy material losses made the survivors at that time unwilling to record them in detail in history books. However, a large number of production equipment and technical materials were damaged in the war, and countless technical personnel died in the war, causing serious technical dynasties. As the saying goes, it is difficult for a good cook to cook without rice. Even if people know many scientific principles and learn from ancient and modern times, they cannot produce them without corresponding supporting production equipment and skilled technicians. Moreover, during the Civil War, researchers who can only be called "powerless to tie a chicken" compared to combatants can be said to be the first batch of people who died.

The cruel reality forced survivors to abandon their original differences and contradictions and live in groups. However, as those high-tech products that were lucky enough to remain in the war were constantly consumed, they were not replenished at all. In order to ensure that the human race can survive on the Firefly Planet in the future without becoming extinct, they had to expand the population of the ethnic group as much as possible. As a result, survivors had to settle for the second best time and time again. In the following few decades, the industrial and agricultural level of the Firefly Planet in the human world rapidly declined from the interstellar era to the level before the 18th century industrial revolution of the parent star.

In the next nearly four hundred years of low-key development, humans in the Firefly Planet have been lying on firewood and tasting their gall to re-develop and grow the endangered population to more than tens of millions of people, and their territory has expanded from a few thousand square kilometers to more than 500,000 square kilometers, which is considered to be barely getting rid of the crisis of population extinction.
