In the not-too-distant modern era, nine coastal cities hand over medical care, transportation, security, energy and identity to the "Mountain and Sea City Cloud". Li Jin, a temporary night shift worker at the funeral home, could hear the strongest words in the relics, but he didn't know whether it was the truth, a lie, or the last wish of the deceased.
An unnamed body requested not to be deleted before cremation. On the same night, sister Li Sang, who was investigating Aoki's sleep plan, lost contact. From this, Li Jin walked into the corpses buried in Yangang, the old fire in Qingqiu, the sealing of the White Tower, the power outage in Chiluo, and the bottom of the Xuanchao Sea. He discovered that the five urban personalities that maintained the order of the nine cities were actually shaped by the memories of the dead in the disaster years and the fears of ordinary people.
They did save countless people, and they did sacrifice people who were not included in the list. When more efficient answers require everyone to surrender their right to make mistakes, journalists, workers, patients, digital personalities, law enforcers, the undocumented and a stray dog will each decide what they are willing to pay and who they refuse to be represented by.
