When the Western Han Dynasty Translucent Mirror awakened in the museum and went berserk, Su Yan, a newcomer to the Special Investigation Bureau, unexpectedly awakened the "Ancient Appraisal Hand" and also tore apart a corner of the truth about the world. The modern state agency "Special Investigation Bureau", the "Weeping Iron Dynasty" that has been hidden for thousands of years, and the mysterious organization "The Spirit Society" - the three parties are engaged in a desperate game around the awakened souls of cultural relics and the heritage of lost civilizations.
Su Yan has the blood of the Weeping Iron Royal Family, and his right hand can resonate with the soul of cultural relics; the soul of the ancient harp has a cold sound, and he has the past of killing gods and the bond of destroying the world; the tactical team leader Chu Xiao controls the AI metaphysical mecha and struggles on the edge of mechanical ascension. They are trapped in the vortex of the three major cultivation systems of "material soul", "blood weapon" and "mechanical spirit", fighting against cultural relic riots, dynasty conspiracy, and AI rebellion.
From the Ten Thousand Souls of the Forbidden City to the advent of alien surveillance, from the resurrection of the Qin Mausoleum Terracotta Warriors to the Interstellar Dimension Court... Human civilization has been revealed as an alien experimental site. Su Yan repairs history with his left hand and tears apart dimensions with his right hand. At the end of human life and death, he must make a choice: should he transform into a cultural relic to protect the remaining fire, or should he ignite a new era with imperfect humanity? "The Ninth Cultural Relics Investigation Bureau" is an epic about the survival of civilization that combines metaphysics, science fiction and national will.
