(Apocalyptic style, supernatural power, not invincible, no system, single female protagonist)
A sudden disaster left a human soul trapped in a corpse.
When he wanted to annihilate his own humanity, he saw new hope
When he worked hard to move towards hope, he destroyed that hope with his own hands.
Is this disaster man-made or an invasion?
The early plot is cliche, please don't enter if you mind.
