"Liu Li Teeth Book" is set in the late Song Dynasty in the Southern Dynasty. It tells the story of the Langya Chu family, a declining noble family, who was involved in the struggle between various forces in order to protect the secret recipe of ancestral dentistry.
In Wuyi Alley, Jiankang City, the Chu family, once the "Sage of the Apricot Grove", is gradually declining. Chu Qingluo, the younger generation, is proficient in medical skills and takes care of precious medicinal gardens every day, paying special attention to a "glazed tooth tree" that is difficult to cultivate - which is closely related to the family's secret "Liu Li Tooth Tree". This secret recipe records the unique skills of treating dental caries. It is not only a symbol of the Chu family's glory, but also the source of disaster.
Chu Qingluo gradually became aware of the anomalies at home: his father Chu Hong looked solemn and secretly ordered someone to move the mysterious box and cage; his grandfather's handwritten copy of "Tooth Book" disappeared from the family study; his grandmother's words revealed her deep concern for the future of the family. Although her father told her to reduce going out because of the "increasing number of refugees outside the city," Chu Qingluo was keenly aware that the real crisis was approaching.
Sure enough, a mysterious person spied outside Chu's house that night. A figure wearing standard attire and a strange emblem on the shoulder was spotted by Chu Qingluo and fled quickly. This confirmed her worries - royal dignitaries, humble military generals, private medical groups and even overseas forces have all set their sights on the "Liu Li Teeth Book". Chu Qingluo stepped forward in the crisis, determined to protect the family inheritance, but she did not know that this battle would reveal the deeper secrets of the previous dynasty behind the secret recipe, and would involve her in the torrent of changes in the times.
