Xuan Ye Wei: Nine Nether Tribulations

"Xuan Ye Wei" - a secret organization established by the founding emperor of Dayin to check and balance the court and monitor the world. It is codenamed "Ye Owl" and is not included in any official documents. Members are secretly selected from orphans, death row prisoners, and marginalized people, trained with special means, and loyal to them for life. They wander in the shadows and deal with all "invisible" matters related to the country - from assassinating rebels to suppressing cults, from tracking down secret treasures to monitoring feudal towns. The Xuanye Guard headquarters is located in the "Yongye Palace" deep underground in the "Fengtian Mansion" in the capital. There are four levels of secret agents: "Heaven, Earth, Xuan, and Huang". The Wei Zhong houses the "Pavilion of Strange Objects" (which collects rare objects from all over the world), the "Secret Archives" (which records royal secrets and taboos in the world), and the "Forbidden Technique Cave" (which seals dangerous classics). The members are all called by code names, and their real names and past have been erased. In the winter of the 19th year of the Apocalypse, the cult "Nine Youmen" that was thought to have been destroyed for more than 80 years reappeared in "Fengtian", the capital of the Yin Dynasty. While investigating a series of disappearances of beggars and refugees, the commander of the Xuan Ye Guards, "Ye Owl-Qi" (Lu Jiuyou), broke through the Jiuyou Gate and used living people to refine the evil sacrifice of "Yin Sha", and rescued a mysterious young man "Tong" who was engraved with the "Jiuyou Blood Eye Seal". As the investigation deepened, Lu Jiuyou discovered that Jiuyou Sect was back with a vengeance, and its plot was far more than just refining corpses to cause chaos. They seem to be looking for the legendary "Key to the Underworld" - an ancient secret treasure said to be able to open the boundary between Yin and Yang and draw in the power of the Nine Springs of the Netherworld. And all of this is inextricably linked to the national destiny of the Yin Dynasty, disputes between feudal lords and towns, and even the mysterious disappearance of the first commander of the Xuan Ye Guards, "Night Owl-Zero" 80 years ago.
