In the ink-filled Songlan Academy, the talented girl Jiang Yanqing is obsessed with ancient books but is distressed by the chaos of textual research. She devoted herself to research and created the original "document spectrometer" method - neither fairy nor fantasy, but using precise word frequency statistics and word meaning correlation network to sort out the context of ancient scrolls. When strange "treasure" clues emerge from the dusty annotations in the Forbidden Library, Yanqing uses the "word vector" model to gain insight into its water conservancy nature, and even uses the "text traceability" algorithm to tear apart the veneer of forged annotations. Facing authoritative suppression and academic shady affairs, she used code as a pen and data as a blade. With the support of her mentor Cui Bingyuan and her close friend Su Wanru, she launched a silent revolution in the academy and promoted the establishment of the "Ancient Books Digital Textual Research Center." From distinguishing the authenticity of a word to establishing the guidelines of an academy, Yanqing used his sincerity and wisdom to clean up the dust in the pile of old papers, and finally made the ink marks of the "Ethical Code of Documentary Criticism" light up the academic sky like stars.
