This world has been dark for too long.
It was so bad that Jin Yiwei's knife could cut anyone at will, so bad that the prince of the current dynasty used human sacrifices as iron cannons in the cellar, and so bad that an embroiderer was skinned and could sew twenty-seven human skins into clothes and wear them. It's so dark that the sweet-scented osmanthus lover who has been waiting for three years only replied "I know". It's so dark that every letter the mute woman has sent to the bridge for twenty years says "come back". It's so dark that someone has been guarding an empty tomb for three hundred years, so dark that he has forgotten who he is waiting for.
But no matter how dark the night is, there is always the moon.
In the wild bamboo forest outside Yongzhou City, the moon is blue. Under the moonlight stood a woman, barefoot, with two silver bells tied to her ankles. She is a bamboo spirit named Ah Qing. She guarded a dead scholar for three hundred years, and in the end she couldn't tell whether she was a monster or a monument. Later, a head catcher came, named Xu, with a dragon-killing knife hanging on his waist. He didn't say a nice word, he raised the knife and chopped the grave. It broke her out of her obsession and turned her into a bamboo fairy who could walk, laugh, block the knife for him and warm his bed.
From then on she followed him. He investigates crimes and she suppresses demons. He drew his sword against this rotten world, and she stood behind him - bamboos emerged from the cracks in the ground to clear the way for him, and silver bells guided him in the night wind. He couldn't sleep with his eyes open at night, so she took off the bell from his ankle and placed it next to his pillow, saying, "You can tell by the sound that I'm still outside."
