When Lin Qiu used the ancestral copper key to open the camphor wood box from 1945, a bronze mirror etched with blood patterns dragged her into the vortex of time and space. Traveling back in time to an antique shop in the Republic of China, she discovered that her grandfather was being hunted when she was young. The ancient mirror that could reflect the past and present actually involved the feud between the Chen family and the Kunlun mirror spirit that had been entangled for thousands of years.
In the neon-swaying old Shanghai beach, Lin Qiu witnessed his own deaths in different eras: a dancer who swallowed gold, a female student who was shot, an archaeological team member who drowned... Each "Lin Qiu" had a bronze dagger stuck in his heart. When the sharp claws of the nine-tailed fox demon tore open the rift in time and space, she realized that she was originally the weapon spirit guarding the Mirror Tomb. She had been reincarnated as a demon king who was awakened by the secret technique of Xu Fudong's journey to the East.
Traveling through the underground palace of the Qin Dynasty and the mirror space of the future, deciphering the golden slips of Wu Zetian's atoning for crimes and the fragments of "Tui Bei Diagram", Lin Qiu touched the bronze ruler of Captain Jin and saw himself repeatedly opening a fatal package in all time and space. When the umbilical cord of the newborn in the delivery room turned into a sealed chain, she finally understood: In this life-and-death game spanning three thousand years, only by cutting off the cause and effect of reincarnation can the fate of human beings and mirrors eating each other end.
