Sui Ye City was very near to the Black Desert, which was the territory of the Devil Kingdom in the Shura World. During her journey, Gu Xijiu learned that the Devil Kingdom in the Shura World was homegrown. The Devil Kingdom was mighty and once occupied two-thirds of the Shura World.
Later, there was a mysterious immortal who appeared in the Shura World. This immortal led the human race to fight against the Devil Kingdom for ten years. Finally, the Devil Kingdom retreated, and in the end, only the Black Desert belonged to the Devil Kingdom.
