In this world, human memories will be condensed into crystal-like "memory bones" and deposited in the brain. Society is ruled by the "Memory Administration", which mines "pure" memories to make crystals to control people's thinking. I am a "memory digger" at the bottom, rummaging through the memory dump every day for valuable fragments in exchange for meager survival supplies. One day I dug up a unique blue memory skeleton. It opened an eye in my palm and suddenly said: "Run, they have tampered with everyone's memory." I was horrified to find that this memory skeleton was the "Pollutant No. 0" Wanted by the administration for hundreds of years. What's even more frightening is that deep in my own memory, the truth of my childhood that was forcibly erased is emerging.
