There is an underlying rule hidden in this world that no one knows about - it becomes invalid every ten years.
Every ten years, the world will automatically screen out and erase a group of "collectively forgotten people". Invalidation is not death, but a complete stripping of existence: their names are cleared from everyone's memory, the images in the photo album disappear automatically, and chat records, ID files, and social traces are all annihilated.
The invalid is still alive, breathing, feeling pain, and having complete life memories, but has completely become a transparent person in the world. Relatives are unknown, friends are strangers, and society has no trace. It is as if he has never been in this world.
What spawned this cruel mechanism was never gods, systems, or higher-dimensional forces, but humankind's collective indifference and selective forgetfulness. People have a habit of forgetting suffering, avoiding debts, and downplaying the sacrifices of ordinary people. Those little people who are not remembered and regretted will be judged by the world as "useless and redundant" and will be cleared and scrapped regularly.
The protagonist is the only invalid restorer in the world, the only one who can see all the erased people and the past, and the only one who has the ability to "repair traces of existence." His mission has never been to change his destiny against the will of heaven and climb to the top to become stronger, but to pick up the tiny pieces of the human world that have been discarded by the times and complete the proof of existence for the unknown.
