Try to survive...
When the critical threshold of reality suddenly collapses, no door or entrance is needed, the world under your feet will twist and collapse in place, and fall into the threshold realm.
Shen Yan was just an ordinary senior high school student. A sudden threshold change dragged her into a twisted space formed by countless obsessions from the past.
There are no system prompts here, and there are no shortcuts to defeat monsters and pass levels. There are only "liminal fragments" - fragments of memories and emotions peeled off in space. Absorbing it can resist space erosion and redeem the lost past, but the price is that the self-personality is slowly swallowed up by foreign consciousness, and eventually turns into a shadow floating in the threshold, completely disappearing in reality.
Thresholds in the world are divided into two groups: some plunder the scraps and exchange part of themselves to survive; some stick to their hearts and struggle to survive the erosion of space.
Shen Yan sticks to the bottom line and refuses to use himself as a bargaining chip for survival. In the repeated threshold areas, he dismantles obsessions and gets a glimpse of human nature.
With space distortions one after another, a stolen childhood memory surfaced, and the truth about the memory storage field built by ancient ancestors was slowly revealed.
If you destroy everything, you can return to the ordinary world, but the price is to bury thousands of unfinished regrets; if you maintain the status quo, you will be trapped in the twisted cracks forever.
When the final choice was before her, she was unwilling to accept a black-and-white fate and wanted to find a third way out in the collapsed realm.
Concept: Obsession is not a monster that should be destroyed. Those reverberations in the threshold are the regrets of people who have truly lived. Destruction is also another kind of harm.
