Chen Xuan, a graduate student in the Department of Archeology, accidentally triggered a Qin Dynasty mechanism during an archaeological excavation in Lishan, and was stabbed in the right eye by a fragment of an ancient bronze mirror that broke out of the ground. From then on, he awakened the S-level secret pupil - he could see through the authenticity of all ancient artifacts, see the memories of the owner of the artifacts during his lifetime, and even trigger thousand-year obsessions hidden in the artifacts. Relying on these eyes, he picked up jade from the Warring States period at a low price, and shocked the antique world by selling it at a sky-high price; he saw the secret behind Bai Qi's trap to kill 400,000 Zhao soldiers from a bronze sword; he read the last memory of the sacrificed girl in the blood-stained jade bracelet, and used rules to design the resentment. But the secret pupil brings not only wealth and fame, but also a destiny of being a guardian that lasts for two thousand years. The mysterious organization "Antiquities Research Association" came to the door, and the receptionist Qin Lan told him: There are three fragments of the bone mirror, and whoever collects them can open the real mausoleum of Qin Shihuang. And her family is the descendant of the "Mirror Keepers" who guarded the tomb of the First Emperor. From the ghost market in Beijing to Shosoin in Japan, from the Kunlun Death Valley to the underground archives of the Vatican, Chen Xuan pursues the fragments and uncovers the truth buried by history. In the end, he stood in front of the bronze door of the Lishan Underground Palace. He faced not only the obsession of the First Emperor two thousand years ago, but also a door that was being knocked open from the inside by an unknown entity. From treasure appraiser to guardian, everything starts with that bone mirror.
