Youdu Heishui

The Mountain of Youdu is located within the North Sea, where the Black Water originates. The mountain is full of black exotic beasts such as black birds, black snakes, black leopards, black tigers, black foxes and tails. In the world view of the novel, this mountain is not a mountain in the ordinary geographical sense, but a place where the two worlds of life and death overlap - half of the mountain exists in the world of the sun, and the other half sinks into the netherworld.
