In 2035, in the cyber era with advanced brain-computer interface technology, a mentally ill patient, Jiang Linan, disguised himself as a seriously ill patient and sneaked into "Renhe Hospital" to investigate the mysterious disappearance of his sister. This seemingly ordinary hospital is actually a secret prison controlled by the Xuanmen Bureau. There are Ming Dynasty sacrificial pits buried underground. Seventy-three superpowers are being used as "living people to raise gu" to feed the Yin soldiers that are about to emerge.
In a ward full of electronic shackles and soul-soothing charms, Jiang Linan met Gu Qinglan, a female partner of the Ke family who held a bronze bell in her hand. The scratches on her neck, the suspended blood beads, and the seventeen repeated reflections of death on the hospital bed revealed the bloody curse of the century-old theater troupe - every half of July, the opera singers who sang "Peony of the Netherworld" will be punished by heaven. When the implanted chip awakens the memory of the previous generation of Celestial Masters, Jiang Linan discovers that his blood can actually melt electronic shackles. The strange photos of his sister Jiang Xue during her lifetime even coincide with the corpse of Zhuangyuan Hong in the incinerator...
