This is a suspenseful fantasy story that took place during the Yongle period of the Ming Dynasty.
The commander of the Jinyi Guards, Su Zhao, received a secret report that strange murders have occurred frequently in Jinling, the capital. The deceased were all people from the Jianghu. Their deaths were bizarre and there were strange runes left on their bodies. Just when the Yamen had nothing to do, the appearance of Yun Xi, a Taoist stranger, brought a turning point to the case.
Yunxi is the daughter of the late Shushan sect master Yun Xianzi, and is proficient in talismans and Taoism. Twenty years ago, her mother Yun Xianzi fought a shocking battle with the cult organization Blood Demon Sect, and finally sealed the Blood Demon Sect at the cost of her own life. Now the Blood Demon Cult is making a comeback, and it seems to be related to a mysterious ritual that was not completed back then.
In order to find out the truth, Yunxi cooperated with Su Zhao. During the investigation, they gradually discovered that there was a shocking conspiracy hidden behind these murders. It not only involves the struggle between Jianghu and Jianghu, but also is closely related to the competition for power in the imperial court. Yunxi himself also gradually uncovered many doubts about his mother's death during the investigation.
As the case progresses, more forces are involved: the mysterious Tianshi Tao, the reclusive elders of Shushan, the secretly plotting by important court officials, and the evil spirits who covet immortality. The various forces are fighting openly and covertly, causing undercurrents in Jinling City. A shocking conspiracy is unfolding in this ancient capital of the empire.
