Misty Firmament

Even a cunning rabbit has three burrows, yet humanity has only one home—Earth.In 2048, Earth's climate officially entered an irreversible phase of warming, forcing humanity to accelerate its search for the path to civilizational survival.

Relocating Earth to another star system is not only nearly impossible but also fails to solve the issue of a “single point of failure.” The only viable strategy within a limited timeframe is to expand humanity’s sphere of activity through advancements in space technology, while also prolonging the lifespan of civilization via developments in biotechnology and artificial intelligence.

In the vast and uncertain universe, the continuation of civilization has become humanity’s ultimate goal. Under this overarching aim, every individual must make their own choice.
