Ji Chengshu, a transcription disciple of the Xuanzhang Sect, discovers scattered ancient formulas among piles of discarded, fragmented scrolls. Together with Xin Ruotang, a disciple specializing in the restoration of old scrolls, and using paper and ink physical evidence alongside practical combat verification, they step by step collate and piece together the lost sect-guarding mental technique, The Guiyi Xuanzhang. Murong Xuanzhang, the Master of the Scripture Pavilion, strictly adheres to the existing kung fu system and scrutinizes the incomplete old methods from multiple perspectives. Neither superstitious about ancient texts nor demeaning new classics, through repeated trial and verification, they drive the sect to re-examine the traditional value of incomplete canons.
