If history can be edited, truth will become the most expensive luxury. A librarian who carries modern memories falls into a parallel Tang Dynasty that is closely monitored by the "Historical Administration". Here, every future idea he sells accelerates the destruction of this world; every person he falls in love with may be erased after the next "system update". He must use the most dangerous knowledge as a weapon to fight a way out for civilization between tampering and truth.
Core innovation: This is not a traditional time-travel novel, but a philosophical fable about a "programmer" who mistakenly enters a "historical operating system". What it explores is: when a person holds knowledge like "God's authority", should he choose to become a new god, or should he protect the final chaos and reality of human nature?
