Once upon a time, humans and demons lived together. Once upon a time, there really was a majestic and magnificent fairy palace in the clouds in the sky. Immortals stepped on the clouds and entered the world, dressed in colorful clothes and having interactions with human beings. Once upon a time, the vast and deep seas were really inhabited by blue dragons, raining and blowing clouds, and beautiful sharks walking out of the waves, bringing to mankind shark gauze as light as feathers and pearls as white as snow.
Once upon a time, the filthy and evil air between heaven and earth would condense and take shape, turning into demons and harming the human world.
Then, in the blink of an eye, everything changed. Everything has turned into stories in myths and dead paintings in fairy tales. People rely on their own memories to inherit these pasts, but gradually forget the fact that they once existed.
When existence was obliterated and reality was regarded as illusion, the god in the unknown sky showed a vague smile, opened his huge palm, and revealed a wonderful plate of Zhenlong, black and white, all of them were his "person".
