At the beginning of the 22nd century, the earth was short of energy. The United Nations decided to launch a migration plan to send a quarter of the population to an Earth-like planet near Proxima Centauri to establish a new civilization. The remaining humans could only survive for several years with the few remaining resources. Therefore, after the last batch of evacuees left, several major forces immediately appeared on the earth and began to plunder each other. The era of plunder begins. People in the era of plunder can only rely on power, otherwise they can only be plundered. The era of plunder lasted for half a century and ushered in the new era. Someone has completely solved the energy problem, and the earth has become a livable planet again. The forces of various factions have unified, and mankind has ushered in a new technological explosion. On the other side, the migration plan failed and they were forced to return to Earth, and they wanted to rule the Earth through force. War is about to break out.
Intention: Survival is also a kind of luck
