In the new Shanghai of 2157, memory is no longer private, but data that can be bought, sold, and tampered with. When memory restorer Lin Yuan repaired the brain-computer interface of an unknown female corpse, he discovered an encrypted "ghost code" - this turned out to be the core logic of the long-lost deep space AI "Crimson". As the investigation deepened, Lin Yuan discovered that the entire city's memory network was being eroded by this code, and his wife, who had been missing for three years, turned out to be the key to it all.
