In the near future era of "data burial", human consciousness can be uploaded to the "spiritual cloud" to obtain digital immortality. The protagonist is a "memory scavenger" responsible for deleting illegal or painful data of the deceased. One day, he received the task of compulsorily digitizing a Chinese culture master who insisted on traditional burial. In the process of cracking the maze of the master's consciousness, he discovered that what the master had encrypted with his lifelong memory was not a private memory, but an annihilated public memory that carried some kind of intangible cultural heritage that was about to be lost. The protagonist is caught in a dilemma: if he completes the mission, he will receive a huge bonus to save his seriously ill relatives; protecting this cultural heritage means fighting against a powerful system and making his relatives lose hope of treatment.
