Yanyun City, located in the southern part of Bozhou, was a medium-sized city with a population of three million. Its location was unremarkable and its terrain was ordinary. There were many similar, inconspicuous cities within the Heavenly Sword Dynasty.
However, very few people knew that King Yama's Palace had a stronghold in Yanyun City.
As the number one dark power in the Central Plains, King Yama's Palace not only had countless experts but also strongholds spread across the various Daozhou. With the exception of a few special ones, nearly every Daozhou had a stronghold. But the Palace had a mysterious origin and acted in unpredictable ways. Therefore, its strongholds were all different and difficult to detect. The organization was also so vast that many forces, even if aware of a stronghold's existence, would turn a blind eye as long as they themselves were not harmed.
