If you had the chance to start over again and again, but had to watch the world end and your beloved die every time, what would you choose?
Ye Yanran is trapped in that very nightmare. Tsunamis, bitter cold, scorching heat, endless days, endless nights... Deadly disasters keep repeating. Each time she comes back to life, she carries more memories and trauma, trying to change an ending that seems inevitable.
She frantically stockpiles supplies, searches for a way to survive, and races against time. But she soon realizes that the greatest threat may not be the disasters themselves. Something is coming with the flood from the depths of the sea, while darkness takes root in the depths of human nature as despair grows.
On this thorn-covered path of rebirth, she is the only one who knows what is coming, and an eternal prisoner.
