In 2197, humans discovered that "memory is not exclusive to the individual" - when an individual's brain dies, its memory will escape to the "memory cloud" in geosynchronous orbit in the form of "neural quantum waves". Scientists have invented "memory transplantation technology" that can "graft" memory fragments of the deceased to living people. However, every time a memory is grafted, the recipient will lose a memory of the same length as himself.
There are only three "Memory Colonization Centers" in the world, and the grafting objects are strictly limited to "civilization compensaters": for example, after the last user of an endangered language dies, his memory is grafted to linguists; when a researcher of a vanished ancient civilization dies suddenly, his archaeological memory is grafted to his successor. However, with the abuse of technology, the "black market of memory colonization" has emerged - rich people graft the memories of artists in pursuit of inspiration, criminals graft the memories of the dead to cover up crimes, and "memory colonizers" gradually experience "memory overflow" in those who receive memories: multiple personality fragments exist in the body at the same time, and can even "retrace" key scenes of the deceased's lifetime through memory, uncovering the hidden secrets of civilization and individual tragedies.
