Lu Zhiheng, a modern cultural relic restorer, travels through time to the Great Xia dynasty. At first, all he wants is to repair artifacts peacefully at the Demon Suppression Bureau's Department of Damaged Relics and get paid by the day. But he soon discovers that a bronze eye he casually restores, a section of bell pattern he repairs, or a crack in a stone beast he fills can make a Martial Saint manifest hundreds of miles away, set bells ringing in twelve cities, or even divert the Cang River. Behind every national treasure supposedly damaged by natural causes lies a systematic alteration of Great Xia's artifact veins by another civilization.
