In Lin'an in the Southern Song Dynasty, there was an undercurrent surging under the prosperity. Lu Xiuyuan, a pawn shop apprentice, is gifted with the ability to perceive the true historical meaning of ancient objects. A bizarre incident made him realize: invisible "corrosion marks" were eroding history, famous paintings were distorted, famous officials disappeared, skills were cut off, and memories were confused... The foundation of China was on the verge of crumbling! Holding the "True Meaning Guide" in his hand, he is a humble tinkerer. Repair the anchor points of antiquities and pursue the erased truth; fight wits and conspiracies of power and deal with mysterious forces; from the changes in "Along the River During the Qingming Festival" to the secrets left in Bianliang, from the lost "General Martial Arts" to the forgotten loyal souls... Lu Xiuyuan uses treasure appraisal as a blade and reasoning as a shield to mend the cracks in history at the edge of the fault. This is a rescue that spans time and space, an epic story in which a little person protects the spark of civilization in silence.
