The area where Zhao Kingdom and Cyan Wolf Ridge have the largest border is mainly divided into two parts.
One is a large river stretching over hundreds of miles. The river water is muddy, bottomless, and flows violently without stop.
The river is filled with whirlpools of various sizes, possessing a strong suction force that even prevents wood and feathers from floating.
This river is called the Sha River, also known as the Ghost River. As its name suggests, entering this river is like seeing a ghost, making survival difficult.
The other is a mountain range extending for hundreds of miles.
The mountains are less than a thousand feet high, but are shrouded all year round in a mysterious black fog that not only confuses the five senses but is also highly poisonous.
This mountain range is called the Black Wind Mountains, and few who enter, whether human or demon, come out alive.
