In 2048, the Earth's climate will officially enter an irreversible warming phase, and mankind will have to accelerate the exploration of the continuation of civilization.

It is too difficult to move the Earth to other galaxies, and it is impossible to solve the problem of “single point of failure”, so we can only broaden the radius of human activities through the development of aerospace science and technology within a limited period of time, and at the same time, we can prolong the survival cycle by means of the development of biotechnology and intelligent science and technology.

Seeking the continuation of civilization in the vast universe has become the highest goal of the whole, under which every individual has to make his own choice.
