Apocalypse Challenge [Infinite]

In 2030, the countdown to the apocalypse begins.

Earthquakes, tsunamis, volcanic eruptions...

A series of natural disasters push human civilization to the brink of destruction.

To select the seeds of civilization, an unknown higher-dimensional galaxy forcibly launches the "Apocalypse Challenge" on Earth.

The number of "seeds" who can survive:

Just 0.01%.

[We fight to survive, and struggle to carry on.

On this final stage, let everyone who bears witness remember:

Humanity may be doomed to perish, but civilization will never die.]

1. There is no Main God space. All "instances" exist in reality and gradually affect the world.

2. The female lead is aloof and destined to stand alone. Her teammates are all temporary; there is no concept of a protagonist team.

3. There is a CP, but very little romance. The plot comes first.

(Sorry for changing the blurb. I left the original too long, and now I can't write it anymore.)

Theme: Seek a way to survive in the midst of despair.
