When Rong Ji, an ancient book restorer at the National Library, was restoring an ancient scroll from the Tang Dynasty of unknown origin, he was sucked into the manuscript and traveled to Chang'an, where Tianbao was fourteen years old. The ancient scroll is called "The Book of Mountains and Rivers", which records the secrets of the mountains, rivers, geography, and city passes in the prosperous Tang Dynasty. It also records an unknown "dark side of Chang'an" - the living lived in the land of squares and guos, and the dead wandered in the netherworld. The secrets sealed in the Book of Mountains and Rivers affect the fate of the entire Tang Dynasty.
The Anshi Rebellion is about to break out, and the mountains and rivers are on the verge of collapse. Under the guidance of a thousand-year-old zombie, Rong Ji discovered that this unprecedented catastrophe was not a natural disaster, but an ancient curse sealed in ancient books. The prosperous age is about to fall, can he use his repair skills to mend the cracks in the sky and protect the mountains and rivers? In the cracks of history, the living and the dead coexist, and cities and mountains and rivers sleep together. What he wants to use his hands to repair is not only the ancient books, but also the devastated human world.
