Shen Du has a secret: when repairing ancient books, he can hear the sounds in the paper.
A drop of blood seeped into "Yongle Dadian", and he became a framer from five hundred years ago. He witnessed the thunder and fire in the Forbidden City and saved a volume of craftsmen's records.
From then on, Juyan Han bamboo slips, Dunhuang scrolls, Southern Song Dynasty medical books... He traveled into ancient books time and time again and became a garrison soldier, carver, and scripture writer - those little people forgotten by official history.
But every time he travels through time, his life is burning. And an organization called "Chi Kiss" is burning all ancient books in an attempt to reset history.
He must find the lost "Xuanhuang of Heaven and Earth" before them - because it records the "soul" of all ancient books and determines the life and death of history.
The paper will rot, but every breath written on the paper will last longer than the stone tablet.
