2250: the Beginning of the Human Interstellar Pioneer Era

In 2250 AD, human civilization faced unprecedented constraints on development after hundreds of years of rapid technological iteration. The earth's traditional fossil energy and new renewable energy have reached the limit of development. Global energy reserves continue to be depleted and can no longer support the high-speed economic system and scientific and technological research and development process of human society. Industrial development has stagnated, resource disputes have occurred frequently, and scientific and technological breakthroughs have hit a bottleneck. Earth's civilization, which once flourished, has completely entered an era of slow and restrained civilizational integration.
