When alien civilization attacks, where should we flee?
When the night returns to darkness, when people return to disorder, when survival becomes a struggle, where is the way forward?
Retreat again and again, there is no retreat behind you, let us hold hands together, I will treasure your heart, treasure it in my heart.
I am no longer afraid of fate, because you are my destiny. From now on wandering, wherever I go, you can only go, and similarly, where you go, I can only go.
Purpose: Survive in the apocalypse
