In the winter of the 16th year of Zhenyuan, Shen Zhen, a graduate student in ancient book restoration, dressed up as a palace maid in Huanyi of Yeting Palace. She was stepped on and humiliated for eavesdropping on Aunt Zheng's complaint about the cleaning of the Jixian courtyard's annex library. She was slapped in the face by reciting ancient texts on the spot, snatched the key and rushed into the annex library. She used batter to mix batter, and hemp rope to remove silk threads to mend the seven wormholes in the remaining volumes of "Jade Pian" with her bare hands. She was caught by Li Xuan, the king of Shu, who was secretly investigating. After the prince's examination, he was promoted to the rank of book repair envoy, responsible for the repair of the treasury. Later, she discovered the secret grid of Beiku during the book revision process, and gradually came into contact with a batch of forgotten old files and border defense letters, and was thus involved in a mysterious clue about the past events on the Longyou-Hexi border. In the process of unraveling the clues, she and Li Xuan went from probing, colluding, to working side by side. While repairing the fragments, they were also repairing a forgotten past event of the Tang Dynasty.
Intention: A book-repairing skill changed my life and a page of the history of the Tang Dynasty.
